1. A display driver integrated circuit (IC), comprising:
a chromatic aberration correction (CAC) circuit configured to:
receive a first input color plane corresponding to a single color,
wherein the single color is a first color, and the first input color plane comprises:
a center region; and
a peripheral region that surrounds the center region of the first input color plane; and
generate an output color plane comprising:
a center region that is the same as the center region of the first input color plane; and
a scaled peripheral region that surrounds the center region of the output color plane, the scaled peripheral region being generated by scaling values of the first color for respective pixels in the peripheral region; and
a drive circuit configured to update a display panel based on the output color plane.
