Abstract
A brightness correction method for a display panel, comprising showing a plurality of image areas in the display panel, wherein the image areas display different colors, each color has a plurality of luminance values according to a plurality of gray values, and wherein each gray value corresponds to a gamma voltage; detecting the luminance values; and adjusting the gamma voltages according to the detected luminance values.
Claims22
A brightness correction method for a display panel, comprising:
- providing a plurality of gray values in a sequence, wherein each gray value corresponds to a gamma voltage;
- for each gray value provided, showing in turn a plurality of image areas in the display panel, wherein the plurality of image areas are defined according to an input signal group, wherein the display panel receives the input signal group, and wherein the image areas display different colors, and each color has a luminance value according to the provided gray value;
- detecting in turn the luminance values of the colors showing in the image areas for each gray value provided;
- and
- adjusting the gamma voltages according to the detected luminance values.
