Title:
METHOD FOR IMPROVING PICTURE DISPLAY QUALITY, AND TIMING CONTROLLER AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/218405
Kind Code:
A1
Abstract:
A method for improving picture display quality, the method comprising: dividing the total grayscale range of a gamma voltage curve of a display apparatus, so as to obtain a plurality of grayscale range sections; acquiring a plurality of pieces of grayscale data of at least one frame of picture to be displayed by the display apparatus, and calculating the proportion of the grayscale data located within each grayscale range section; according to the proportions obtained by means of calculation, adjusting division values of gamma voltage range sections corresponding to the grayscale range sections in the gamma voltage curve, such that the division value of the gamma voltage range section corresponding to the grayscale range section with the largest proportion is less than the division values of the gamma voltage range sections corresponding to the remaining grayscale range sections; and according to the adjusted gamma voltage curve, outputting gamma voltages corresponding to the plurality of pieces of grayscale data.
