Title:
PIXEL CIRCUIT, DRIVING METHOD THEREFOR AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2020/140489
Kind Code:
A1
Abstract:
A pixel circuit (100), a driving method therefor and a display panel. The pixel circuit (100) comprises: a light-emitting element (110); a drive sub-circuit (120) for generating a current which enables the light-emitting element (110) to emit light; first and second light-emitting control sub-circuits (130, 140), which are respectively constructed to provide, under the control of a first control signal (Con1) and to a first end of the light-emitting element (110), the current which enables the light-emitting element (110) to emit light; a drive control sub-circuit (150), which provides, under the control of a second control signal (Con2), a data signal (Data) to the drive sub-circuit (120); and a reset sub-circuit (160), for resetting, under the control of a first reset signal (Reset1) and a second reset signal (Reset2), the drive sub-circuit (120), the first end of the light-emitting element (110) and a second node (N2) by means of using a first voltage (V1). The pixel circuit (100) is capable of inhibiting residual images.
