Grayscale compensation method and apparatus of display device
A grayscale compensation method and apparatus are provided. The grayscale compensation method includes: performing a grayscale compensation data detection on a display panel to obtain a first grayscale compensation data; preforming a grayscale compensation data detection on a backlight module to obtain a second grayscale compensation data; performing a data fusion on the first grayscale compensation data and the second grayscale compensation data to obtain a third grayscale compensation data; and performing a grayscale compensation on the display panel according to the third grayscale compensation data. By calculating the grayscale compensation data of the display panel and the backlight module at the same time, display brightness of the display panel is more uniform. Moreover, before the data fusion, the first and second grayscale compensation data may be reduced in resolution, the data amount of fusion calculation is less and the calculation time and storage space are saved.
