Pixel unit circuit, method for driving the same, and pixel circuit
摘要
說明書
In actual operations, because photo-electric conversion may only be achieved when the photosensitive diode PD is in the reverse bias state, the direction of a PIN junction of the PD in the example shown in
As shown in
The sub-pixel sub-unit circuit includes the data writing sub-circuit 11, the storage capacitor sub-circuit 12, the driving transistor DTFT and the light emitting element 13. The sub-pixel sub-unit circuit is connected to at least two display signal lines and at least two display signal terminals.
The pixel compensation sub-unit circuit includes the reading control sub-circuit 21 and the photosensitive sub-circuit 22 configured to convert light emitted from the light emitting element 13 to an electrical signal. The pixel compensation sub-unit circuit is connected to at least two compensation signal lines and a compensation signal terminal.
The at least two display signal lines may include the first gate line Scan1 and the data line Data. The at least two display signal terminals may include the first voltage input terminal and the second voltage input terminal. The at least two compensation signal lines may include the second gate line Scan2 and the reading line RL. The plurality of compensation signal terminals may include the third voltage input terminal VI3.
