Title:

PIXEL DRIVE CIRCUIT AND DISPLAY PANEL

Document Type and Number:

WIPO Patent Application WO/2020/215430

Kind Code:

A1

Abstract:

A pixel drive circuit and a display panel. The pixel drive circuit employs a seven-transistor-three-capacitor structure to effectively compensate a threshold voltage of a driving transistor (T1) in each pixel. The pixel drive circuit has a simple compensation structure and the operational difficulty is low. Since a light-emitting device (D) emits light in a programming stage (t4) and a light emission stage (t5), the light-emitting device (D) has an extended light emission duration, thereby increasing the brightness and service life of a display panel.
