Samsung Electronics today showcased its latest innovations for the connected home. During its IFA 2023 press conference, the company highlighted its vision for SmartThings is to enable consumers across Europe to prioritise the topics they care about from saving energy, increasing security and access to great entertainment to making their everyday lives more efficient. The ever-growing SmartThings ecosystem allows its 285 million users to adapt and personalise their homes to suit their needs, seamlessly connecting and controlling multiple appliances and devices via one app.

 

Samsung’s presence at IFA 2023 comes as the company shares new consumer research, conducted across Europe to understand evolving needs for technology in the home.1

 

“Samsung is passionate about connecting our users to the people, places and pastimes that matter most to them,” said Benjamin Braun, Chief Marketing Officer, Samsung Europe. “We will continue to take advantage of the possibilities offered by the latest innovations in technology to make sure the SmartThings ecosystem grows and develops in a way that allows people to make even more of the connections that matter.”

 

 

Enhancing the At-Home Experience

The SmartThings app allows users to control their homes from anywhere, helping them to enjoy seamless entertainment as well as keeping them safe. Across Europe, our homes continue to be more important than ever as they play multiple roles each day  from offices to places for relaxation and entertainment. Seven in ten consumers (71%) agree that technology has a positive impact on their everyday living, including how they interact with their friends and family, how they conduct their chores and how they enjoy their hobbies.¹

 

Now, those with a passion for food can fully connect themselves to the joy of cooking and eating with Samsung Food, the new all-in-one app for recipe searching, saving and sharing, meal planning, cooking and grocery shopping. Announced at the press conference, Samsung Food is available in 104 countries and eight languages and puts the world’s food knowledge at users’ fingertips, empowering them to make the food, health and cooking decisions that are right for them. It also connects to users’ kitchens, instantly sending the right time and temperature to their compatible Samsung oven. With more than 160,000 recipes, there will always be something new to cook.

 

By the end of the year, using Food AI, Samsung Food will provide personalised recipes reflecting users’ dietary requirements, such as converting recipes into a vegan version in just a few taps. In a further enhancement due later this year, it will link with Samsung Health so tailored meal plans can be adapted to suit preferences and dietary requirements, as well as support users in reaching their health goals. In 2024, using Vision AI technology, Samsung Food will use photos taken of meals to check nutritional information, recognise ingredients and recommend the best recipes to use them in.

 

As the number one TV brand for 17 years in a row,2 Samsung has an unrivalled commitment to entertainment. It has completed its super screen line up with the launch of the 98” Neo QLED 8K and 4K Q80C and plans to bring its full range of Micro LED screens to Europe by the end of the year, offering incredible contrast and jaw-dropping detail that places viewers in the middle of the action whether gaming or watching films.

 

To celebrate Disney’s 100th anniversary, Samsung has announced the launch of The Frame  Disney100 Edition. Featuring an exclusive bezel in the Disney 100 signature platinum silver metal and a unique Mickey Mouse inspired Disney remote. It also comes with 100 pieces of iconic art from Walt Disney Animation Studios, Pixar Animation Studios, Marvel, Lucasfilm and National Geographic, as well as classic images of Mickey, Minnie, Woody, Cinderella and many others. Users can also display their family photos for a magical home environment.

 

Also announced at the press conference was the global launch of The Freestyle 2nd Gen. This versatile, portable projector delivers a big screen experience wherever the user chooses even on the ceiling. The Smart Edge Blending feature offers landscape and portrait screen experiences, meaning two Freestyle 2nd Gen projectors can be paired to give a 160” panoramic and 120” vertical viewing experience. What is more, with complete access to the Samsung Gaming Hub, users of the Freestyle 2nd Gen can enjoy the biggest games from Samsung’s streaming partners.

 

In partnership with Xbox and Bethesda Softworks, this now includes Starfield, the stunning, next-generation role-playing game set amongst the stars. Playable through the Samsung Gaming Hub with an Xbox Game Pass Ultimate membership, without the need for a console.

 

 

Taking Small Steps for Our Planet

Samsung is committed to developing products and services that help people save money and take steps towards a better planet. These topics are high on the agenda for consumers too, over three quarters (77%) say they seek out tech products that save energy  not only to save money, but for the benefit of the environment too.4 Two-thirds (67%) also consider it important that their next appliance can connect to an app that allows them to monitor and reduce their energy consumption.4

 

With energy prices increasing across Europe,3 72% of those asked are concerned about the cost of running appliances in their home.4 To help combat this, SmartThings Energy can help users optimise the energy used across their appliances to suit their needs and lower usage. For example, AI Energy Mode in SmartThings Energy allows you to monitor and reduce your washing machine’s energy use by up to 70%5 by using Ecobubble to wash with cool water instead of warm.

 

Samsung has also partnered with global ocean conservation organisation Ocean Wise and apparel maker Patagonia to find solutions to the issue of microfiber shedding. The Less Microfiber™ Filter is an external washing machine filter that cuts up to 98% of microplastic emissions from laundry cycles.6 Speaking at IFA, Charlie Cox, Manager of Microplastic Solutions at Ocean Wise said, “Through our collaboration with Samsung and Patagonia, Ocean Wise is proud to have shown a way for industry to play its part in stemming the flow of microfibers into the ocean. Through innovations like the Less Microfiber™ Filter, we can empower individuals to reduce their microfiber footprint at home. It is a simple, everyday solution that our oceans will thank us for.”

 

Heating technologies like heat pumps represent a rapidly growing market, and Samsung is at the forefront of this growth. Its innovative smart air source heat pumps have seen an unprecedented 97% growth in sales since 2022.7 These work with domestic hot water tanks or with Samsung’s ClimateHub, to make your home comfortable all year round, whatever the weather. They can also connect to the SmartThings ecosystem, so their energy use can be monitored and tailored to the user’s preferred environment.8 The latest addition to its range of high temperature monobloc heat pump solutions, the EHS Mono R290, launches in September.

 

Samsung’s journey is constantly evolving as it aims to design technology that helps people make the most of their day while taking small steps to reduce our environmental impact. The Galaxy Z Flip59 and Z Fold510 and the Galaxy Tab S9 series11 feature a variety of recycled materials, including recycled aluminium, glass and plastics sourced from ocean-bound discarded fishing nets, water barrels and PET bottles. Even the Galaxy Watch6 series incorporate post-consumer recycled plastics. All of these Galaxy innovations come in packaging boxes made using recycled paper material.12

 

 

Keeping Your Home Secure

Samsung understands the reassurance that smart technology can provide across the generations. Security was an emerging theme from the research conducted. Watching their home while they aren’t there (54%), feeling safer when home alone (39%) and keeping their family safe when they are out of the house (39%) are seen as the key safety benefits of smart technology.13

 

The SmartThings ecosystem includes a range of partners who are committed to helping people keep their homes and loved ones safe. This now includes Yale, a leading brand in home security. The Yale Linus® Smart Lock and the new Smart Opener for Gate & Garage enable doors and gates to be locked remotely via the app to ensure peace of mind for all family members.

 

 

Unlocking the Future Through Smart Technology

Samsung is invested in a future built around the possibilities that technology can unlock. One area it aims to make a difference is in making the technology for smart homes more easily available. The research shows a quarter of Europeans consider the inclusion of smart technology to be a key factor in the desirability of their next home and over three quarters of respondents said fully functional smart homes are appealing (77%).12

 

Understanding this, Samsung is working to make these possibilities a reality and it believes in the power of collaboration when it comes to driving this vision forward. By partnering with ABB Smart Buildings and SMA, one of the world’s leading providers of photovoltaic and storage system technology, it hopes to connect people more closely to their homes by embedding the possibilities of smart technology into houses before they are bought. By integrating ABB and SMA products into SmartThings Energy, homes can become even safer, smarter and more sustainable. For example, the ability to run appliances at the optimum time, tracking energy use to adjust consumption based on energy prices and usage patterns and optimising energy use based on solar production.

      The cinema industry is undergoing a profound transformation. As audiences increasingly seek premium and luxury experiences, theaters are evolving to deliver immersive, differentiated environments — and Samsung Electronics is at the forefront of this revolution.
       
      Raising the bar for cinema innovation, Samsung unveiled the latest model of Onyx (ICD) in March. The next generation of cinematic experiences will be defined by immersive visuals, improved comfort and a reliable viewing experience.
       
      In this article, Samsung Newsroom takes a closer look at the company’s vision for the future of cinema in terms of Visuals, Space and Consistency.
       
      ▲ Samsung Onyx was the center of attention at the company’s booth at CinemaCon 2025, the industry’s largest exhibition
       
       
      Visuals — An Out-of-This-World Screen Experience
      Immersion is at the heart of the cinematic experience — a setting designed to transport audiences into the world of the film. Only in an environment free from the everyday distractions such as constant calls, notifications and household chores can viewers fully engage with the story unfolding on the screen.
       
      A true cinematic experience faithfully delivers the filmmaker’s vision, presenting every detail, color and shadow exactly as intended. Onyx brings that vision to reality.
       
      ▲ Pixar’s Inside Out 2 shown on Samsung Onyx, demonstrating the display’s peak brightness and vibrant color accuracy
       
      Onyx, the world’s first cinema LED display certified1 by Digital Cinema Initiatives (DCI), delivers superior picture quality in 4K HDR resolution with vivid colors, deep blacks and infinite contrast. The clarity, precision and rich detail in each frame help give life to the narrative. Gone are the days of poor edge resolution and inconsistent brightness.
       

       
      ▲ Samsung Onyx enhances Pixar’s Lightyear (top) and Soul (bottom) with outstanding contrast, making dark scenes more vivid and immersive
       
      The Onyx screen can lend its brightness and clarity to applications other than movie screenings — live sports, concerts, gaming events and corporate presentations, for example. The ability to host alternative content empowers theaters to diversify their offerings and create new revenue streams without compromising the premium viewing experience.
       
      ▲ A live concert seen on Onyx, demonstrating the display’s color accuracy and sharp details
       

      Space — More Room for Comfort and Flexibility
      Comfort and spatial design are also key factors that set premium cinemas apart. Much like the distinction between economy and business class on an airplane, the seating experience can make or break a theater’s appeal. As theaters evolve into premium auditoriums, spacious, comfortable seating becomes essential.
       
      Onyx helps enable this transformation. Unlike traditional projectors which require separate projection rooms and large setups, Onyx’s cinema LED technology maximizes the available space in a theater. This allows cinemas to optimize their auditorium spaces and provides more flexibility to install specialized seating like larger recliners or dining tables.
       
      Furthermore, new Onyx (ICD) offers flexible scaling options, allowing screens to be customized to fit the dimension of each auditorium, ensuring the best use of space without sacrificing picture quality and comfort.
       
      ▲ Pixar’s Elio screened on Samsung Onyx featuring luxury seating for a premium cinema experience
       
      With Onyx, every seat in the theater offers a reliable high-quality visual experience — no edge distortion or resolution loss — ensuring that the entire audience is fully immersed in the story. The combination of optimized space, enhanced comfort and stunning visuals elevates the overall cinema experience.
       
      ▲ Samsung Onyx empowers theaters to deliver a premium cinema experience and luxury dining for customers.
       
       
      Consistency — Reliable Viewing Quality With Smarter Management Tools
      We go to the theater to be transported — to lose ourselves in the world of a story. But experiences in traditional projection-based theaters can deteriorate with picture quality that varies depending on the age and condition of the equipment.
       
      Samsung’s Cinema LED screen, on the other hand, features an ‘Auto Calibration Solution’ that automatically adjusts color consistency across each module, ensuring optimal picture quality — not just at installation, but every step of the way through ongoing maintenance.
       
      Onyx also offers the industry’s first and longest 10-year warranty for cinema LED,2 raising the bar for long-term reliability in cinema technology.
       
      ▲ Samsung Onyx, an out-of-this-world cinema LED display
       
      Since debuting the world’s first Cinema LED screen in 2017, Onyx has built strong partnerships with major global film studios, earning trust and recognition across the industry. As the leader in Cinema LED technology, Samsung is committed to pushing boundaries — so the magic of the movies is always seen exactly as it was meant to be.

      “One of the reasons Samsung focused on quantum dots is their exceptionally narrow peaks of the emission spectrum.”
      — Sanghyun Sohn, Samsung Electronics
       
      In 2023, the Nobel Prize in Chemistry was awarded for the discovery and synthesis of quantum dots. The Nobel Committee recognized the groundbreaking achievements of scientists in the field — noting that quantum dots have already made significant contributions to the display and medical industries, with broader applications expected in electronics, quantum communications and solar cells.
       
      Quantum dots — ultra-fine semiconductor particles — emit different colors of light depending on their size, producing exceptionally pure and vivid hues. Samsung Electronics, the world’s leading TV manufacturer, has embraced this cutting-edge material to enhance display performance.
       
      Samsung Newsroom sat down with Taeghwan Hyeon, a distinguished professor in the Department of Chemical and Biological Engineering at Seoul National University (SNU); Doh Chang Lee, a professor in the Department of Chemical and Biomolecular Engineering at the Korea Advanced Institute of Science and Technology (KAIST); and Sanghyun Sohn, Head of Advanced Display Lab, Visual Display (VD) Business at Samsung Electronics, to explore how quantum dots are ushering in a new era of display technology.
       
      Understanding the Band Gap Quantum Dots – The Smaller the Particle, the Larger the Band Gap Engineering Behind Quantum Dot Films Real QLED TVs Use Quantum Dots To Create Color  

       
       
      Understanding the Band Gap
       
      “To understand quantum dots, one must first grasp the concept of the band gap.”
      — Taeghwan Hyeon, Seoul National University
       
      The movement of electrons causes electricity. Typically, the outermost electrons — known as valence electrons — are involved in this movement. The energy range where these electrons exist is called the valence band, while a higher, unoccupied energy range that can accept electrons is called the conduction band.
       
      An electron can absorb energy to jump from the valence band to the conduction band. When the excited electron releases that energy, it falls back into the valence band. The energy difference between these two bands — the amount of energy an electron must gain or lose to move between them — is known as the band gap.
       
      ▲ A comparison of energy band structures in insulators, semiconductors and conductors
       
      Insulators like rubber and glass have large band gaps, preventing electrons from moving freely between bands. In contrast, conductors like copper and silver have overlapping valence and conduction bands — allowing electrons to move freely for high electrical conductivity.
       
      Semiconductors have a band gap that falls between those of insulators and conductors — limiting conductivity under normal conditions but allowing electrical conduction or light emission when electrons are stimulated by heat, light or electricity.
       
      “To understand quantum dots, one must first grasp the concept of the band gap,” said Hyeon, emphasizing that a material’s energy band structure is crucial in determining its electrical properties.
       
       
      Quantum Dots – The Smaller the Particle, the Larger the Band Gap
       
      “As quantum dot particles become smaller, the wavelength of emitted light shifts from red to blue.”
      — Doh Chang Lee, Korea Advanced Institute of Science and Technology
       
      Quantum dots are nanoscale semiconductor crystals with unique electrical and optical properties. Measured in nanometers (nm) — or one-billionth of a meter — these particles are just a few thousandths the thickness of a human hair. When a semiconductor is reduced to the nanometer scale, its properties change significantly compared to its bulk state.
       
      In bulk states, particles are sufficiently large so the electrons in the semiconductor material can move freely without being constrained by their own wavelength. This allows energy levels — the states that particles occupy when absorbing or releasing energy — to form a continuous spectrum, like a long slide with a gentle slope. In quantum dots, electron movement is restricted because the particle size is smaller than the electron’s wavelength.
       
      ▲ Size determines the band gap in quantum dots
       
      Imagine scooping water (energy) from a large pot (bulk state) with a ladle (bandwidth corresponding to an electron’s wavelength). Using the ladle, one can adjust the amount of water in the pot freely from full to empty — this is the equivalent of continuous energy levels. However, when the pot shrinks to the size of a teacup — like a quantum dot — the ladle no longer fits. At that point, the cup can only be either full or empty. This illustrates the concept of quantized energy levels.
       
      “When semiconductor particles are reduced to the nanometer scale, their energy levels become quantized — they can only exist in discontinuous steps,” said Hyeon. “This effect is called ‘quantum confinement.’ And at this scale, the band gap can be controlled by adjusting particle size.”
       
      The number of molecules within the particle decreases as the size of the quantum dot decreases, resulting in weaker interactions of molecular orbitals. This strengthens the quantum confinement effect and increases the band gap.1 Because the band gap corresponds to the energy released through relaxation of an electron from the conduction band to the valence band, the color of the emitted light changes accordingly.
       
      “As particles become smaller, the wavelength of emitted light shifts from red to blue,” said Lee. “In other words, the size of the quantum dot nanocrystal determines its color.”
       
       
      Engineering Behind Quantum Dot Films
       
      “Quantum dot film is at the core of QLED TVs — a testament to Samsung’s deep technical expertise.”

      Quantum dots have attracted attention across a variety of fields, including solar cells, photocatalysis, medicine and quantum computing. However, the display industry was the first to successfully commercialize the technology.
       
      “One of the reasons Samsung focused on quantum dots is the exceptionally narrow peaks of their emission spectrum,” said Sohn. “Their narrow bandwidth and strong fluorescence make them ideal for accurately reproducing a wide spectrum of colors.”
       
      ▲ Quantum dots create ultra-pure red, green and blue (RGB) colors by controlling light at the nanoscale, producing narrow bandwidth and strong fluorescence.
       
      To leverage quantum dots effectively in display technology, materials and structures must maintain high performance over time, under harsh conditions. Samsung QLED achieves this through the use of a quantum dot film.
       
      “Accurate color reproduction in a display depends on how well the film utilizes the optical properties of quantum dots,” said Lee. “A quantum dot film must meet several key requirements for commercial use, such as efficient light conversion and translucence.”

      The quantum dot film used in Samsung QLED displays is produced by adding a quantum dot solution to a polymer base heated to a very high-temperature, spreading it into a thin layer and then curing it. While this may sound simple, the actual manufacturing process is highly complex.
       
      “It’s like trying to evenly mix cinnamon powder into sticky honey without making lumps — not an easy task,” said Sohn. “To evenly disperse quantum dots throughout the film, several factors such as materials, design and processing conditions must be carefully considered.”
       
      Despite these challenges, Samsung pushed the boundaries of the technology. To ensure long-term durability in its displays, the company developed proprietary polymer materials specifically optimized for quantum dots.
       
      “We’ve built extensive expertise in quantum dot technology by developing barrier films that block moisture and polymer materials capable of evenly dispersing quantum dots,” he added. “Through this, we not only achieved mass production but also reduced costs.”
       
      Thanks to this advanced process, Samsung’s quantum dot film delivers precise color expression and outstanding luminous efficiency — all backed by industry-leading durability.
       
      “Brightness is typically measured in nits, with one nit equivalent to the brightness of a single candle,” explained Sohn. “While conventional LEDs offer around 500 nits, our quantum dot displays can reach 2,000 nits or more — the equivalent of 2,000 candles — achieving a new level of image quality.”

      * DCI-P3 (Digital Cinema Initiatives – Protocol 3): A color space widely used for digital HDR content, defined by Digital Cinema Initiatives for digital projectors
       
      By leveraging quantum dots, Samsung has significantly enhanced both brightness and color expression — delivering a visual experience unlike anything seen before. In fact, Samsung QLED TVs achieve a color reproduction rate exceeding 90% of the DCI-P3 (Digital Cinema Initiatives – Protocol 3) color space, the benchmark for color accuracy in digital cinema.
       
      “Even if you have made quantum dots, you need to ensure long-term stability for them to be useful,” said Lee. “Samsung’s industry-leading indium phosphide (InP)-based quantum dot synthesis and film production technologies are testament to Samsung’s deep technical expertise.”
       
       
      Real QLED TVs Use Quantum Dots To Create Color
       
      “The legitimacy of a quantum dot TV lies in whether or not it leverages the quantum confinement effect.”
      — Taeghwan Hyeon, Seoul National University
       
      As interest in quantum dots grows across the industry, a variety of products have entered the market. Nonetheless, not all quantum dot-labeled TVs are equal — quantum dots must sufficiently contribute to actual image quality.
       
      ▲ Taeghwan Hyeon
       
      “The legitimacy of a quantum dot TV lies in whether or not it leverages the quantum confinement effect,” said Hyeon. “The first, fundamental requirement is to use quantum dots to create color.”
       
      “To be considered a true quantum dot TV, quantum dots must serve as either the core light-converting or primary light-emitting material,” said Lee. “For light-converting quantum dots, the display must contain an adequate amount of quantum dots to absorb and convert blue light emitted by the backlight unit.”
       
      ▲ Doh Chang Lee
       
      “Quantum dot film must contain a sufficient amount of quantum dots to perform effectively,” repeated Sohn, emphasizing the importance of quantum dot content. “Samsung QLED uses more than 3,000 parts per million (ppm) of quantum dot materials. 100% of the red and green colors are made through quantum dots.”
       
        
      Samsung began developing quantum dot technology in 2001 and, in 2015, introduced the world’s first no-cadmium quantum dot TV — the SUHD TV. In 2017, the company launched its premium QLED lineup, further solidifying its leadership in the quantum dot display industry.

      “Samsung’s QLED technology played a crucial role in bringing quantum dots to the level of recognition needed for the Nobel Prize in Chemistry.”
      — Taeghwan Hyeon, Seoul National University
       
      Quantum dots have been at the forefront of display innovation over the past decade, delivering some of the most accurate color reproduction among existing materials. In 2015, Samsung Electronics paved the way for the commercialization of quantum dots with the launch of SUHD TVs — a breakthrough that moved beyond the use of cadmium (Cd), a heavy metal traditionally utilized in quantum dot synthesis, by introducing the world’s first no-cadmium quantum dot technology.
       
      The academic world took notice. The successful commercialization of cadmium-free quantum dot TVs not only set a new direction for research and development but also played a pivotal role in the awarding of the 2023 Nobel Prize in Chemistry for the discovery and synthesis of quantum dots.
       
      Following Part 1, Samsung Newsroom uncovers how Samsung has contributed to academia through groundbreaking advances in material innovation.

      Why Cadmium Was the Starting Point for Quantum Dot Research
       
      “I was truly impressed that Samsung succeeded in commercializing a no-cadmium quantum dot display product.”
       — Taeghwan Hyeon, Seoul National University
       
      Quantum dots began attracting scientific interest in the 1980s when Aleksey Yekimov, former Chief Scientist at Nanocrystals Technology Inc., and Louis E. Brus, a professor emeritus in the Department of Chemistry at Columbia University, each published their researches on the quantum confinement effect and the size-dependent optical properties of quantum dots.
       
      Momentum accelerated in 1993 when Moungi Bawendi, a professor in the Department of Chemistry at the Massachusetts Institute of Technology (MIT), developed a reliable method for synthesizing quantum dots. In 2001, Taeghwan Hyeon, a distinguished professor in the Department of Chemical and Biological Engineering at Seoul National University (SNU), invented the “heat-up process” — a technique for producing uniform nanoparticles without the need for size-selective separation. In 2004, Hyeon published a scalable production method in the academic journal Nature Materials — a discovery widely regarded as a potential game changer in the industry.

      However, these efforts did not immediately lead to commercialization. At the time, quantum dots relied heavily on cadmium(Cd) as a core material — a substance known to be harmful to humans and designated as a restricted material under the European Union’s Restriction of Hazardous Substances (RoHS) Directive.
       
      “Currently, the only materials capable of reliably producing quantum dots are cadmium selenide (CdSe) and indium phosphide (InP),” explained Hyeon. “Cadmium selenide, the conventional quantum dot material, is a compound of group II and group VI elements, while indium phosphide is formed from group III and group V elements. Synthesizing quantum dots from group II and VI elements is relatively straightforward, but combining group III and V elements is chemically much more complex.”
       
      ▲ A comparison of cadmium-based quantum dots with ionic bonds and indium-based quantum dots with covalent bonds
       
      Cadmium, an element with two valence electrons, forms strong ionic bonds1 with elements like selenium (Se), sulfur (S) and tellurium (Te) — each of which has six valence electrons. These combinations result in stable semiconductors, known as II–VI semiconductors, materials that have long been favored in research for their ability to produce high-quality nanocrystals even at relatively low temperatures. As a result, the use of cadmium in quantum dot synthesis was considered an academic standard for many years.
       
      In contrast, indium (In) — an alternative to cadmium with three valence electrons — forms covalent bonds2 with elements such as phosphorus (P), which has five valence electrons. Covalent bonds are generally less stable than ionic bonds and have a directional nature, increasing the likelihood of defects during nanocrystal synthesis. These characteristics have made indium a challenging material to work with in both research and mass production.
       
      “It is difficult to achieve high crystallinity in quantum dots made from indium phosphide,” Lee noted. “A complex and demanding synthesis process is required to meet the quality standards necessary for commercialization.”
       
       
      No Compromise – From Breakthrough to Mass Production
       
      “There is simply no room for compromise when it comes to consumer safety.”
      — Sanghyun Sohn, Samsung Electronics
       
      Samsung, however, took a different approach.
       
      “We had been researching and developing quantum dot technology since 2001,” said Sanghyun Sohn, Head of Advanced Display Lab, Visual Display (VD) Business at Samsung Electronics. “But early on, we determined that cadmium — which is harmful to the human body — was not suitable for commercialization. While regulations in some countries technically allow up to 100 parts per million (ppm) of cadmium in electronic products, Samsung adopted a zero-cadmium policy from the start. No cadmium, no compromise — that was our strategy. There is simply no room for compromise when it comes to consumer safety.”
       
      ▲ Sanghyun Sohn
       
      Samsung’s long-standing commitment to its principle of “No Compromise on Safety” came to the forefront in 2014 when the company successfully developed the world’s first no-cadmium quantum dot material. To ensure both durability and image quality, Samsung introduced a triple-layer protective coating technology that shields indium phosphide nanoparticles from external factors such as oxygen and light. The following year, Samsung launched the world’s first commercial SUHD TV with no-cadmium quantum dots — a paradigm shift in the display industry and the culmination of research efforts that began in the early 2000s.
       
      “Indium phosphide-based quantum dots are inherently unstable and more difficult to synthesize compared to their cadmium-based counterparts, initially achieving only about 80% of the performance of cadmium-based quantum dots,” said Sohn. “However, through an intensive development process at the Samsung Advanced Institute of Technology (SAIT), we successfully raised performance to 100% and ensured reliability for more than 10 years.”
       
      ▲ The three components of quantum dots
       
      Quantum dots found in Samsung QLEDs are composed of three key components — a core, where light is emitted; a shell, which protects the core and stabilizes its structure; and a ligand, a polymer coating that enhances oxidation stability outside the shell. The essence of quantum dot technology lies in the seamless integration of these three elements, an advanced industrial process that spans from material acquisition and synthesis to mass production and the filing of numerous patents.
       
      “None of the three components — core, shell or ligand can be overlooked,” added Lee. “Samsung’s technology for indium phosphide synthesis is outstanding.”
       
      “Developing a technology in the lab is a challenge in itself, but commercialization requires an entirely different level of effort to ensure product stability and consistent color quality,” said Hyeon. “I was truly impressed that Samsung succeeded in commercializing a no-cadmium quantum dot display product.”
       
       
      Setting the Quantum Dot Standard
       
      “Research trends in the academic community shifted noticeably before and after the release of Samsung’s quantum dot TVs.”
      — Doh Chang Lee, Korea Advanced Institute of Science and Technology
       
       
      The optical properties of quantum dots are being applied to a wide range of fields, including solar cells, medicine and quantum computing. However, the quantum dot display remains the most actively researched and widely commercialized application to date — with Samsung emerging as a pioneer.
       
      Building on years of foundational research and the introduction of its SUHD TVs, Samsung launched its QLED TVs in 2017 and set a new standard for premium displays. In 2022, the company pushed innovation further with the debut of QD-OLED TVs — the world’s first display to combine quantum dots with an OLED structure.
       
      ▲ A comparison of LCD, QLED and QD-OLED structures
       
      QD-OLED is a next-generation display technology that integrates quantum dots into the self-emissive structure of OLED. This approach enables faster response times, deeper blacks and higher contrast ratios. Samsung’s QD-OLED was awarded Display of the Year in 2023 by the Society for Information Display (SID), the world’s largest organization dedicated to display technologies.
       
      “Samsung has not only led the market with its indium phosphide-based quantum dot TVs but also remains the only company to have successfully integrated and commercialized quantum dots in OLEDs,” said Sohn. “By leveraging our leadership in quantum dot technology, we will continue to lead the future of display innovation.”
       
      ▲ Doh Chang Lee
       
      “Research trends in the academic community shifted noticeably before and after the release of Samsung’s quantum dot TVs,” said Doh Chang Lee, a professor in the Department of Chemical and Biomolecular Engineering at the Korea Advanced Institute of Science and Technology (KAIST). “Since its launch, discussions have increasingly focused on practical applications rather than the materials themselves, reflecting the potential for real-world implementation through display technologies.”
       
      “There have been many attempts to apply quantum dots in various fields including photocatalysis,” he added. “But these efforts remain in the early stages compared to their use in displays.”
       
      Hyeon also noted that the successful commercialization of Samsung’s quantum dot TVs helped pave the way for Bawendi, Brus and Yekimov to receive the 2023 Nobel Prize in Chemistry.
       
      “One of the most important criteria for the Nobel Prize is the extent to which a technology has contributed to humanity through commercialization,” he said. “Samsung’s QLED represents one of the most significant achievements in nanotechnology. Without its commercialization, it would have been difficult for quantum dots to earn Nobel recognition.”
       

      Samsung’s Vision for Tomorrow’s Displays
      Since the launch of its QLED TVs, Samsung has accelerated the growth of quantum dot technology in both industry and academia. When asked about the future of quantum dot displays, the experts shared their insights on what lies ahead.
       
      “As a next-generation technology, we are currently exploring self-emissive quantum dots,” said Sohn. “Until now, quantum dots have relied on external light source to express red and green. Going forward, we aim to develop quantum dots that emit light independently through electroluminescence — producing all three primary colors by injecting electrical energy. We are also working on the development of blue quantum dots.”
       
      “As electroluminescent materials make it possible to reduce the size of device components, we’ll be able to achieve the high resolution, efficiency and brightness required for virtual and augmented reality applications,” said Lee, predicting a major transformation in the future of displays.
       
      “A good display is one the viewer doesn’t even recognize as a display,” said Sohn. “The ultimate goal is to deliver an experience that feels indistinguishable from reality. As a leader in quantum dot display innovation, we will proudly continue to move forward.”
       
      With its continued leadership and bold technological vision, Samsung is shaping the future of displays and rewriting what’s possible with quantum dots.
