Abstract:
1. A display device, comprising: a gray scale value counting module, operatively receiving image data of each frame and generating a gray scale value counting signal according to the image data of each frame; a ratio generating module coupled to the gray scale value counting module, operatively generating a ratio value signal according to the gray scale value counting signal; a first sub-frame function module coupled to the ratio generating module, operatively receiving the image data of each frame and the ratio value signal, creating a first gamma curve function according to a first formula and the ratio value signal, and generating first sub-frame image data according to the first gamma curve function and the image data of each frame; a second sub-frame function module coupled to the ratio generating module, operatively receiving the image data of each frame and the ratio value signal, creating a second gamma curve function according to a second formula and the ratio value signal, and generating second sub-frame image data according to the second gamma curve function and the image data of each frame; and a display panel coupled to the first sub-frame function module and the second sub-frame function module, operatively configured for displaying a first sub-frame image according to the first sub-frame image data and displaying a second sub-frame image according to the second sub-frame image data, wherein the first formula is F wherein a gamma value of the display device corresponds to an original gamma curve function, the f
