Abstract
The present application discloses a backlight module brightness calibration method. The method includes: a brightness detection step, a grayscale sorting step, a grayscale calibration table generation step, and a grayscale calibration table output step. The present application re-sorts first grayscale values of a grayscale range of backlight divisions of a display device according to actual brightness values to obtain a grayscale calibration table to further mitigate or avoid a technical issue of a discontinuous or jump-varying grayscale transition of a backlight module of a conventional display device.
