OLED Color at 1/3 the Price: QD Vision’s Quantum Dots Enable TCL’s Launch of 4K UHD TVs with Full-Gamut Color
The new 55-in. quantum dot display, developed in partnership with QD Vision Inc., is a light emitting technology that uses semiconductor nanocrystals similar to those in organic light-emitting diode (OLED) displays. The displays also use a small quantity of cadmium sealed within the glass display to enhance colors.
"QD Vision makes quantum dots with very narrow red and green light output. The result in the LCD system is that you get good color separation between red, green and blue light and hence pure saturated color on screen," Mazzuchi said in an email reply to Computerworld.
Quantum dot technology was first implemented commercially by Sony in 2013 in multiple flat-screen TV models. Now other TV and monitor makers are starting to follow suit.
Research shows that “colorfulness” is the single most important perceptual factor in viewers’ estimation of picture quality. Until now, most mainstream LCD TV designs have had to sacrifice color quality, typically only delivering 60-70% of the NTSC color gamut standard. Color IQ is capable of delivering 100% of the NTSC color gamut, and works with all major LCD applications, including LCD TVs, LCD monitors and other displays, providing both superior color performance and high system efficiency.
The new TVs will initially be available in China, followed by additional worldwide availability.
