First Claim
Patent Images
1. A method for adjusting luminance of a display screen, comprising:
- obtaining a current luminance value of each pixel in a preset grayscale image of a display screen, wherein the preset grayscale is any grayscale lower than a preset grayscale threshold;
determining a target luminance value of each pixel;
adjusting luminance of some or all of the pixels according to the current luminance value and the target luminance value of each pixel, so that a luminance value of each pixel reaches the target luminance value.
