Quantum dot content

The true quality of a quantum dot TV is defined by 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 colour expression that only quantum dots can deliver.

Samsung QLEDs eliminate the need for a separate phosphor layer, enhancing light and energy efficiency while delivering more vivid colours. A quantum dot OLED (QD-OLED), which consists of a thin-film transistor (TFT) layer,1 a self-emitting light source and a quantum dot film that uses the light emitted from the light source, takes a step further enhancing picture quality. In either case, a dedicated quantum dot film that contains sufficient quantum dots is key in delivering top-class picture quality and longevity.

In the early stages of developing quantum dot TVs, cadmium was essential to achieving the key benefits of quantum dots such as colour reproduction and contrast ratio. At the time, cadmium was considered the most efficient material for producing quantum dots.

However, cadmium’s toxicity became a significant obstacle to the commercialisation of quantum dot technology. The element posed serious threats to the environment — making its widespread use difficult despite being the most suitable material for implementing quantum dot technology.

In response to this challenge, Samsung developed the world’s first no-cadmium quantum dot material in 2014 and successfully commercialised quantum dot technology with its SUHD TVs in the following year to open a new era of quantum dot TVs.

10 Years of quantum dot innovation and leadership

Samsung has quickly recognised the potential of quantum dot technology and led innovation in the global display market over the past decade through continuous research and investment.

Samsung began researching and developing quantum dot technology in 2001 — at a time when there was limited research on non-cadmium materials. Achieving vivid colours required making the nano-sized particles uniform, but the lack of technology and research made mass production extremely challenging.

Despite these obstacles, Samsung succeeded in creating a no-cadmium nanocrystal material in 2014. Since then, the company has accumulated extensive expertise — registering more than 150 patents — and continuously worked on advancing the technology. Samsung’s long-standing commitment culminated in 2015 when the company unveiled the world’s first SUHD TVs with no-cadmium quantum dot technology.
