Abstract
A method for performing dynamic peak brightness control in a display module and an associated timing controller are provided. The method includes: calculating a maximum value and a minimum value of a previous image to determine a contrast ratio (CR) of the previous image; calculating a maximum level quantity (MLQ) of the previous image, wherein the MLQ represents a number of pixels corresponding to the maximum value; performing pixel data mapping on original pixel data of a current image according to a first gain corresponding to the MLQ, to generate intermediate pixel data of the current image; and performing selective pixel data adjustment on the intermediate pixel data according to a second gain corresponding to the CR and the MLQ, to generate updated pixel data of the current image, for being displayed on a display panel of the display module, wherein the updated pixel data replaces the original pixel data.
