Bringing better pixels to UHD with Quantum Dots
The next wave of market push for TVs is Ultra-High Definition. The increase in resolution from HD to 4K is perhaps the most well known benefit of UHD but there is much more to this new broadcast specification. High dynamic range (HDR) and wide color gamut bring more perceptible benefits to users in terms of an improved viewing experience than improved resolution alone. The ultra-high color gamut standard Rec. 2020 was originally defined for laser-based projectors where the color primaries are on the color locus of the CIE diagram. Because of the deeply saturated color coordinates, Rec. 2020 is beyond the capabilities of OLEDs. Is the Rec. 2020 color standard reachable for consumer displays or is it only for high-end laser-based projection systems? This presentation explores the capability of using quantum dots in LCDs to reach the ultra-high color gamut of Rec. 2020.
