Title:
PIXEL DRIVING CIRCUIT, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/205530
Kind Code:
A1
Abstract:
A pixel driving circuit, a display panel, and a display device. The pixel driving circuit comprises a first reset transistor (Ts1) connected between a first reset voltage terminal (Vcm) and the gate of a driving transistor (Td), a first capacitor (C1) connected in series between the gate of the driving transistor (Td) and one of the source (S) or drain of the driving transistor (Td), and a second capacitor (C2) connected in series between the first capacitor (C1) and a second voltage terminal (OVSS) to reduce the effect of a threshold voltage of the driving transistor (Td) on a driving current, thereby ensuring the light emitting stability of a light emitting device (D1).
