72.4: Development of a Laser Optical System for a 4K Laser Backlit LCD TV

Abstract

We have developed a Laser Backlight LCD TV that uses red laser diodes and cyan LEDs. The laser diode is smaller divergence angle than the LED. Therefore in the backlight we have developed an optical system suitable to the characteristics of the laser light with a simple configuration.

10‐4: A 13.3‐inch 8K x 4K 664‐ppi 120‐Hz 12‐bit Display with Super‐wide Color Gamut for the BT.2020 Standard

“…On the other hand, the standard BT.2020 covering a significantly wider color gamut than sRGB has been proposed as a next-generation video coding standard for 8K displays ratified by the International Telecommunications Union Radiocommunications Sector (ITU-R) in 2012. While the color gamut of BT.2020 can reproduce 99.9% of the object colors, it has been realized only by a quantum-dot display and a laser display [8,9].…”
