Title:
PIXEL DRIVING CIRCUIT, ORGANIC LIGHT-EMITTING DISPLAY PANEL AND PIXEL DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/109690
Kind Code:
A1
Abstract:
Disclosed are a pixel driving circuit, an organic light-emitting display panel and a pixel driving method. The driving circuit comprises: a switch sub-circuit (10), a driving sub-circuit (11), a storage capacitor (C) and a charge elimination sub-circuit (13), wherein a control end of the charge elimination sub-circuit (13) is connected to a first scanning signal line (GN-1), and the other ends are respectively connected to a first end of the driving sub-circuit (11), a cathode of an organic light-emitting element (OLED) and a reference voltage end (VSS) so as to invert a potential between an anode and the cathode of the organic light-emitting element under the control of the first scanning signal line (GN-1). The driving circuit can improve the light-emitting efficiency of an organic light-emitting element, and can also improve the service life thereof.
