Document Type and Number:
WIPO Patent Application WO/2022/134149
Kind Code:
A1
Abstract:
Provided are a pixel driving circuit and a display panel. The pixel driving circuit comprises a first transistor, a second transistor, a first capacitor, a second capacitor and an organic light-emitting diode, wherein the second transistor is a low-temperature polysilicon transistor. The present invention can improve the phenomenon of picture flickering caused by a relatively large leakage current of the display panel, and is favorable for improving the brightness uniformity.
