Pixel circuit, driving method thereof and display device
A pixel circuit, a driving method and a display device. The pixel circuit includes a light emitting unit; a drive transistor configured to drive the light emitting unit to emit light to display an image frame; and a control circuit configured to control the drive transistor according to signals on control lines. The method of controlling includes: resetting, in a reset stage of an image frame, a voltage of the first electrode of the drive transistor by applying a reset voltage, and sensing, in a sense stage, a threshold voltage of the drive transistor by applying a reference voltage. The control circuit is further configured to control, in an offset elimination stage at the beginning of the image frame and prior to the reset stage, the drive transistor to be switched off, which was in an ON state at the end of a previous image frame.
