1. A processing system, comprising:
a first integrated circuit (IC); and
a second IC,
wherein the first IC comprises:
a first interface configured to receive first image element data and second image element data;
first communication circuitry configured to transfer the first image element data to first image processing circuitry and the second image element data to the second IC, wherein the first image processing circuitry is configured to generate a first overlay image by overlaying a first partial input image with a first image element based on the first image element data;
first display panel driver circuitry configured to drive a display panel based on the first overlay image,
wherein the second IC comprises:
second communication circuitry configured to receive the second image element data from the first IC;
second image processing circuitry configured to generate a second overlay image by overlaying a second partial input image with a second image element based on the second image element data; and
second display panel driver circuitry configured to drive the display panel based on the second overlay image.
