1. A display driver comprising:
image processing circuitry configured to:
receive ambient light distribution data defining a distribution of ambient light on a display panel, wherein the display panel is foldable between a folded position and an unfolded position;
receive folding information generated in response to the display panel being in the folded position;
obtain a blending ratio for each subpixel of a pixel of the display panel using the ambient light distribution data and the folding information;
generate a blended parameter set for each subpixel by blending a plurality of parameter sets based on a position of the pixel and the blending ratio;
perform image processing of input pixel data using the blended parameter set to generate output voltage data; and
drive circuitry configured to drive the display panel based on the output voltage data.
