Scope

Scope: This document specifies the technical requirements and measurement methods for the brightness curve corresponding to the pixel gray scale value and brightness value of LCD display devices. This document applies to LCD displays, LCD modules, and LCD terminals that display standard dynamic range images, but does not apply to LCD devices that display high dynamic range (HDR) images. Main technical content: Since LCD display technology relies on the opening and closing of light valves for display, if the brightness and gray scale relationship formula of traditional display devices such as CRT, PDP, and LED is followed, the best image display effect cannot be achieved. To prevent LCD display devices from being forced to discard certain gray scales and reduce the picture performance, this standard is proposed to improve the picture quality of LCD display devices.
