Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/060430
Kind Code:
A1
Abstract:
A pixel circuit and a driving method therefor, and a display panel. The pixel circuit comprises: a driving module (10), a storage module (20), a coupling module (30), a first reset module (40), a second reset module (50), a discharge module (60), a data writing module (70), and a light-emitting control module (80). The storage module (20) is electrically connected to a control end (N1) and a first end (N2) of the driving module (10), respectively; a first end (30) of the coupling module is electrically connected to the first end (N2) of the driving module (10); the first reset module (40) is electrically connected to a second end (N3) of the coupling module (30); the second reset module (50) is electrically connected to the control end (N1) of the driving module (10); the discharge module (60) is electrically connected to a second end (N4) of the driving module (10); the data writing module (70) is electrically connected to the second end (N3) of the coupling module (30), and a data voltage (Vdata) is input to the data writing module (70); the light-emitting control module (80) is connected to the driving module (10) and a light-emitting device (L) between a first power supply and a second power supply. The pixel circuit can ensure the brightness uniformity, high resolution, and high refresh rate of the display panel.
