Abstract
The present disclosure provides a grayscale compensation method, a gray-scale compensation assembly, and a liquid crystal display device. The gray-scale compensation method includes: detecting a display region for compensation in the liquid crystal display screen that needs grayscale compensation under a reserved liquid crystal response time; acquiring a grayscale conversion timetable of the liquid crystal display screen, and obtaining a limit value of conversion time of the liquid crystal display screen according to the grayscale conversion timetable; acquiring a compensation grayscale lookup table of the display region for compensation; comparing the reserved liquid crystal response time and the limit value of conversion time to obtain a time comparison result; performing grayscale compensation on the display region according to the time comparison result, the grayscale conversion timetable and the compensation grayscale lookup table.
