“…Changing the light source of the backlight from conventional LEDs to lasers, therefore, is necessary. Previous research reported that LCDs with a laser backlight satisfy the BT.2020 color gamut [3][4][5][6][7]. These laser backlights use laser diodes as light sources.…”

“…Therefore, changing the light source of the backlight from conventional light‐emitting diodes (LEDs) to lasers is required. It was reported that LCDs with the laser backlight instead of the conventional LED backlight satisfy the BT.2020 color gamut [2–5]. A laser diode was used as a light source.…”

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.
