Title:
PIXEL DRIVING CIRCUIT AND CONTROL METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/000380
Kind Code:
A1
Abstract:
The present application relates to the technical field of display. Provided are a pixel driving circuit and a control method therefor, and a display device. The pixel driving circuit is configured to drive a light-emitting diode to emit light at different refresh frequencies, and comprises: a first control module, a second control module, a compensation module, a refreshing module, a first reset module, a first light emission control module, a driving module and a second light emission control module. According to the pixel driving circuit provided by the present application, the potential of a first node and the potential of a second node are maintained, such that the pixel driving circuit can operate at different refresh frequencies, and the problem of insufficient Vth detection time is effectively solved.
