How a Nobel Prize-winning discovery unlocks the excellence of QD-OLED
Learn how the Nobel Prize-winning discovery of quantum dots has impacted the world of nanotechnology and the unique color experience of the Samsung QD-OLED.
The Nobel Prize in Chemistry 2023 awarded to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov
The 2023 Nobel Prize has been awarded to three scientists credited with “the discovery and synthesis of quantum dots”. Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov were granted the prize on October 4th after succeeding in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots (QDs), are now of great importance in nanotechnology.
QDs are extremely small semiconductor particles – only 2-10 nanometers (nm) in diameter. Due to their small size, they have unique optical and electrical properties. One of the most intriguing properties of the QD is the relationship between its size and color. The size and shape of quantum dots can be precisely controlled during manufacturing, thus making them “easy” to scale and excellent for use in a variety of display electronics.
With the ability of QDs to produce extraordinary picture quality, Samsung Display is powered by this innovative nanotechnology. The Samsung QD-LED is unlike previous WOLED (white OLED) or LCD displays that rely on color filters to tune the image, QD-OLED’s color conversion, allows for a far superior color performance. The QD-OLED’s narrow band, primary color emission provides the ideal tri-luminous source which has the power to create more than 90 percent coverage of BT.2020 and 99 percent coverage of the Digital Cinema Initiatives’ DCI-P3 color space. This unparalleled color representation can reproduce almost all of the colors visible in nature.
The discovery of quantum dots is set to bring great benefits to our everyday lives. Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication. Find out more about the prize-winning work here.
