Title:
PIXEL DRIVING CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/021465
Kind Code:
A1
Abstract:
A pixel driving circuit (100) and a display panel. The pixel driving circuit (100), during a reset stage, charges via a pre-charging loop (L1) the voltage of a first end of a bootstrap capacitor (C2) to a driving voltage (VDD); during a data writing stage, receives a data voltage (Vdata) via the bootstrap capacitor (C2) and charges an energy storage capacitor (C1) via the bootstrap capacitor (C2) so as to regulate the voltage of the control end of a driving transistor (M) to a second voltage; and during a light-emitting stage, enables the driving transistor (M) to drive, on the basis of the second voltage and the driving voltage (VDD), a light-emitting element (OLED) to emit light, thereby eliminating the phenomena of uneven display brightness.
