Title:
PIXEL CIRCUIT, DISPLAY PANEL, DRIVING METHOD AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/231097
Kind Code:
A1
Abstract:
A pixel circuit, a display panel, a driving method, and a display apparatus. The pixel circuit comprises a light-emitting element (E0), a drive circuit (11), a first energy storage circuit (12), a second energy storage circuit (13), a write-in control circuit (14) and a first control circuit (10). A first end of the first energy storage circuit (12) is electrically connected to a control end of the drive circuit (11), and a second end of the first energy storage circuit (12) is electrically connected to a first end of the drive circuit (11). A first end of the second energy storage circuit (13) is electrically connected to the control end of the drive circuit (11). Under the control of the first write-in control signal, the write-in control circuit (14) controls the connection or disconnection between a write-in end (DW) and a second end of the second energy storage circuit (13). Under the control of the first control signal, the first control circuit (10) controls the connection or disconnection between a voltage end (Vd) of a power supply and the first end of the drive circuit (11). The drive circuit (11) generates, under the control of the potential of the control end thereof, a driving current for driving the light-emitting element (E0). The current type pixel circuit which is applied to an organic light emitting diode display and can achieve threshold voltage self-compensation is provided.
