Abstract

A circuit device is used in a display device. The display device includes a display panel and a backlight including a plurality of light sources. The circuit device includes a distortion correction circuit, a failure information acquisition circuit, a position information acquisition circuit, and a host interface circuit. The distortion correction circuit executes distortion correction on input image data to output output image data after the distortion correction. The failure information acquisition circuit acquires failure information of the light sources. The position information acquisition circuit converts panel-side light source position information, which is position information of a faulty light source indicated by the failure information on the display panel, into input-side light source position information, which is position information of the faulty light source on the input image data. The host interface circuit outputs the input-side light source position information to a host.
