Seventeen-inch laser backlight in-plane switching liquid crystal display with 8K, 120-Hz driving, and BT.2020 color gamut

摘要

We have developed a 17-inch laser backlight in-plane switching liquid crystal display satisfying the main BT.2020 specifications, which are 8K, 120-Hz driving, and a BT.2020 wide color gamut. The color gamut of the developed in-plane switching liquid crystal display covers 98% of the BT.2020 wide color gamut, thanks to a laser backlight and appropriate color filters. The liquid crystal response time of 5 ms, which is sufficient for 120-Hz driving, is achieved by adapting a faster in-plane switching liquid crystal display, namely, the short-range lurch control in-plane switching liquid crystal display.
