Display Controller, Display System, and Electronic Device

Abstract

A display system includes a host device, a display controller, and a display panel. The display panel includes a pixel array including a plurality of subpixels each including a light-emitting display element and a reflective display element. The host device sends image data DT0 to the display controller. The display controller has the following functions: color classification of the image data DT0; generation of attribute data based on the classification result; generation of image data DT1 from the image data DT0; generation of two kinds of image data DT2_e and DT2_r through image processing of the image data DT1 in accordance with the attribute data; generation of image data DT3_e from the image data DT2_e; and generation of image data DT3_r from the image data DT2_r. The image data DT3_e is displayed by the light-emitting display element, and the image data DT3_r is displayed by the reflective display element.
