Quantum dots have emerged as a groundbreaking innovation, transforming the landscape of display technology with applications ranging from cutting-edge televisions to medical devices and solar cells. In 2014, Samsung Electronics spearheaded a significant development by creating a no-cadmium quantum dot material, successfully launching quantum dot technology with their SUHD TVs. Since 2017, the company has maintained its leadership in this field through its QLED series, which continues to build on the legacy of quantum dot mastery.

Quantum Dots: TheNext Generation of Display Innovation

Quantum dots are minuscule semiconductor particles, thousands of times thinner than a human hair. Their unique physical properties, including superior color accuracy and brightness, have positioned them to revolutionize display technology. In practical terms, these properties translate to a wide color gamut that closely matches what the human eye perceives and allows for pixel-level light adjustment, resulting in more precise black levels and reducing blue light exposure. This makes for a more comfortable viewing experience. Emitting light in all directions, quantum dots ensure uniform brightness and consistent color from any viewing angle.

What Sets Quantum Dot TVs Apart: Content, Film Quality, and No-Cadmium Technology

The television industry has invested heavily in the commercialization of quantum dots, recognizing their potential to transform display technology. However, the quality and implementation of quantum dot technology vary significantly among TVs. Critical factors affecting a premium viewing experience include the amount of quantum dot content, the caliber of the quantum dot film, and the use of no-cadmium materials.

Quantum Dot Content

The true measure of a quantum dot TV’s quality lies in its quantum dot content. The quantum dot film requires a minimum of 3,000 parts per million (ppm) of the material to achieve the vivid, rich picture quality and color expression that only quantum dots can deliver.

Quantum Dot Film

Samsung QLEDs eliminate the need for a phosphor layer, enhancing light and energy efficiency while delivering more vivid colors. Additionally, Quantum Dot-OLED (QD-OLED) technology, which includes a thin-film transistor (TFT) layer, a self-emitting light source, and a quantum dot film that utilizes the emitted light, further elevates picture quality. In both cases, a dedicated quantum dot film containing sufficient quantum dots is crucial for delivering top-class picture quality and longevity.

No-Cadmium Technology

In the early stages, cadmium was essential for achieving the key benefits of quantum dots, such as superior color reproduction and contrast ratio. Cadmium’s effectiveness, coupled with its availability, made it a go-to material. However, cadmium’s toxicity posed significant environmental and health risks, hindering its widespread use.

Samsung overcome these challenges. In 2014, the company developed a no-cadmium quantum dot material and successfully commercialized it the following year with the launch of their SUHD TVs, marking a new era of quantum dot technology.

10 Years of Quantum Dot Innovation and Leadership

Samsung has been at the forefront of quantum dot technology for over a decade, continuously investing in research and development to maintain its leadership in the global display market. Starting in 2001, when research on non-cadmium materials was limited, Samsung began exploring and developing quantum dots. Achieving vivid colors through nano-sized particles was a breakthrough, but mass production was challenging due to technological and research limitations.

Samsung has devised and implemented a cutting-edge approach to protection, effectively safeguarding critical infrastructure from a wide array of potential threats. This system’s resilience ensures its reliability and long-term protection, even in the face of evolving threats.

Quantum Dot – The Next Decade

The journey continued, and in 2015, Samsung unveiled its first SUHD TVs equipped with no-cadmium quantum dot technology. Building on this foundation, Samsung introduced its QLED lineup in 2017, setting a new benchmark for premium TVs that surpassed the limitations of OLED technology. By utilizing metal quantum dot technology, Samsung achieved the Digital Cinema Initiatives’ color standard, DCI-P3, and attained 100% color volume for the first time, offering unparalleled color expression. Additionally, the use of inorganic quantum dot technology protected the screens from burn-in, ensuring consistent picture quality over time.

Following the success in 2019 of developing a red light-emitting element for displays, Samsung enhanced the luminous efficiency of blue self-emitting QLEDs—considered the most challenging to implement among the three primary QLED colors—to an industry-leading 20.2% Additionally, Samsung discovering a blue material for self-emitting QLEDs and demonstrating industry-leading performance at the device level were significant achievements of this research. Samsung’s distinctive quantum dot technology has once again overcome technical barriers.
