Title:
PIXEL DRIVE CIRCUIT AND METHOD, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/242319
Kind Code:
A1
Abstract:
The present invention relates to the technical field of display, and in particular, to a pixel drive circuit and a pixel drive method, and a display device. The pixel drive circuit comprises a first input device, a second input device, a drive transistor, a compensation sub-circuit, an isolation device, a reset device, and an energy storage device. According to the present invention, the influence of a threshold voltage of a drive transistor and a wire impedance voltage drop on a drive current can be eliminated and the consistency of drive currents output by pixel drive circuits can be ensured, so that the uniformity of the display brightness of pixels is ensured. In addition, by resetting a first pole of an electroluminescent component, the influence of a previous frame of signal can be eliminated.
