Abstract: A backlight calibration method and device, and a computer equipment are provided. Wherein, the method is used in the display equipment. A detector disposed toward backlight sources of the display equipment to detect backlight parameters of the display equipment is disposed in the display equipment. The method includes obtaining backlight parameters of the display equipment; determining a backlight type corresponding to the backlight parameters; and performing backlight calibration on the display equipment according to the backlight type. A technical problem of easily misusing the parameters during backlight calibration in the prior art is solved.

Abstract: The present disclosure discloses a liquid crystal display panel and a compensation method thereof. The compensation method firstly acquires a plurality of consecutive and alternating odd-numbered frame grayscale data and even-numbered frame grayscale data, then determines a minimum grayscale difference, and determines a gamma voltage difference corresponding to the grayscale difference according to a curve of a relation between grayscales and gamma voltages, followed by obtaining a correction value for a common voltage based on the gamma voltage difference. The flicker phenomena can be improved by adjusting the common voltage only once with the correction value.
