$QTMM Industry Changing 91% Rec2020 Color Gamut Achieved with Quantum Dot LED by Quantum Materials
Quantum dot developer Quantum Materials has announced its achievement of testing a 100% cadmium-free remote phosphor quantum dot LED technology that achieved a 91% Rec2020 color gamut coverage. Quantum Materials has been working with several LED producers, display manufacturers and chemical companies with the technology, aiming to bring the new solution to the current industry.
A way for the solution to achieve wide color gamut display is to deposit red and green quantum dots directly on the surface of a blue phosphor driven backlight LED, Quantum Materials has developed cadmium-free green quantum dots with a narrow FWHM (full width at half maximum) of 16 nanometers to meet the needs.
According to Quantum Materials, producing narrow color emission materials that have high stability and are cadmium-free is very challenging. However, the company is able to manufacture small semiconductors with precise emission wavelengths that possess high stability characteristics when placed in close proximity to LEDs. Through the combination of these materials with Quantum Materials’ red quantum dots and the proprietary encapsulation process, a color gamut of 91% Rec2020 was achieved.
In addition to materially widening the color gamut rendering capability of displays, the company’s quantum dot solution can improve the viewing angles and display brightness by eliminating additional film layers, allowing more light to reach the display viewing surface. This variant of quantum dot display technology also holds the potential to provide additional manufacturing flexibility by being a true "drop in" solution. Aside from the achievement of wide color gamut, Quantum Materials’ QD LED has also passed the 10,000 hour on-time testing level.
