Abstract
A method for enhancing luminance uniformity of a display panel that includes multiple sub-pixels for a same color element is proposed to include: measuring, for each of the sub-pixels, luminance at multiple predetermined luminance codes, so as to obtain a plurality of data points; performing a two-stage curve fitting to obtain a fitting function that describes a curve fitting the data points; and performing demura operation on an image to be displayed by the display panel based on the fitting function.
