Abstract:
A display driver that includes image processing circuitry and a source driver. The image processing circuitry is configured to perform a burn-in compensation to determine a first compensated luminance value for a first pixel in a first area of a display panel based at least in part on a first accumulated luminance value for the first pixel. The first area has a first pixel layout. The image processing circuitry is further configured to scale a second accumulated luminance value for a second pixel in a second area of the display panel to determine a scaled accumulated luminance value. The second area has a second pixel layout different from the first pixel layout. The image processing circuitry is further configured to perform a burn-in compensation to determine a second compensated luminance value for the second pixel based at least in part on the scaled accumulated luminance value.
