Title:
CHARGE RELEASE CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/184989
Kind Code:
A1
Abstract:
Disclosed is a charge release circuit, comprising at least one photosensitive control circuit (10), wherein each photosensitive control circuit (10) is connected to at least one pixel circuit. Each pixel circuit comprises a discharge circuit (20) connected to the photosensitive control circuit (10), as well as a first capacitor (C1) that is connected to the discharge circuit (20) and that is configured to store a display drive signal. The photosensitive control circuit (10) is configured to control the discharge circuits (20) to be turned on in a state in which a backlight source of the display device is turned off so as to release residual charge from the first capacitor (C1), and control the discharge circuits (20) to be turned off in a state in which the backlight source of the display device is turned on so that the pixel circuit controls the display device to display.
