Abstract
A display device and a luminance and color compensation method thereof are provided. The luminance and color compensation method includes: calculating a plurality of compensation values of a plurality of display pixels of a plurality of setting grayscale values based on at least one selected color; recording the compensation values to obtain look-up information; receiving a plurality of image grayscale values of a display image, and obtaining a plurality of selected compensation values respectively corresponding to the display pixels according to the look-up information based on the image grayscale values; and respectively compensating display luminance of the display pixels according to the selected compensation values.
Claims18
A luminance and color compensation method, adapted to a self-luminous display panel, comprising:
- calculating a plurality of compensation values of a plurality of display pixels of a plurality of setting grayscale values based on at least one selected color;
- recording the compensation values to obtain look-up information;
- receiving a plurality of image grayscale values of a display image, and obtaining a plurality of selected compensation values respectively corresponding to the display pixels according to the look-up information based on the image grayscale values;
- and
- respectively compensating display luminance of the display pixels according to the selected compensation values,
- wherein the compensation values are calculated according to a color complementary principle.
(canceled)
A display device, comprising:
- a display panel;
- and
- a controller, coupled to the display panel and configured to:
- calculate a plurality of compensation values of a plurality of display pixels of a plurality of setting grayscale values based on at least one selected color;
- record the compensation values to obtain look-up information;
- receive a plurality of image grayscale values of a display image, and obtain a plurality of selected compensation values respectively corresponding to the display pixels according to the look-up information based on the image grayscale values;
- and
- respectively compensate display luminance of the display pixels according to the selected compensation values,
- wherein the compensation values are calculated according to a color complementary principle.
