Abstract
A charge release circuit includes a plurality of pixel circuits and at least one photosensitive control circuit, and each photosensitive control circuit is connected to at least one pixel circuit. Each pixel circuit of the at least one pixel circuit includes: a discharge circuit connected to the photosensitive control circuit, and a first capacitor connected to the discharge circuit and configured to store a display driving signal. The photosensitive control circuit is configured to control the discharge circuit to be turned on in a state where a backlight of a display device is turned off to release residual charges in the first capacitor.
