Claim 9:
10. A system, comprising:
a display panel comprising a plurality of display pixels;
processing circuitry configured to generate image data to be displayed on the display panel; and
image compensation circuitry configured to:
receive an indication that a display pixel of the plurality of display pixels is a defective display pixel;
convert a gray level of the image data corresponding to the defective display pixel into a luminance domain to generate a target luminance that would have been emitted by the defective display pixel;
deactivate the defective display pixel such that the defective display pixel is fully dark;
determine a point spread function based on a physical pixel arrangement of the plurality of display pixels on the display panel; and
distribute the target luminance of the defective display pixel to a nearby plurality of non-defective display pixels of the display panel within a distance of the defective display pixel according to the point spread function.
