Abstract: A circuit and method facilitate driving a display panel to display an image with improved brightness uniformity are disclosed. In the circuit, an image information extraction sub-circuit extracts, and sends to a compensation processing sub-circuit, display information of each of the plurality of pixels based on the image. The compensation processing sub-circuit then divides a display region of the display panel into a plurality of sub-regions, obtains an average brightness value of each sub-region, and further determines whether a compensation is needed for displaying the image based on a uniformity of the average brightness values of all sub-regions. If so, the compensation processing sub-circuit further performs compensation to an input voltage and/or an effective light output area of each of the pixels to be lightened in each sub-region to thereby obtain an improved brightness uniformity when displaying the image.
