Title:
PIXEL DRIVE CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2023/231099
Kind Code:
A1
Abstract:
A pixel drive circuit (100) and a display panel. The pixel drive circuit comprises: a drive transistor (T1), the drive transistor and a light-emitting element (L) being connected in series between a first power cable and a second power cable; a data transistor (T4) electrically connected to a gate (G) of the drive transistor (T1); and a boost module (10) used for loading a boost input signal (CK), the output end of the boost module (10) being electrically connected to the gate (G) of the drive transistor (T1), so as to increase the voltage of the gate from a first voltage (Vg1) to a second voltage (Vg2). Electrode plates of a first capacitor (C1), a second capacitor (C2) and a third capacitor (C3) are connected to a same node (A).
