Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/016760
Kind Code:
A1
Abstract:
A pixel circuit and a driving method therefor, and a display apparatus. An input end of an anode reset transistor (T7) is connected to an output end of a driving transistor (T1), and an output end of the anode reset transistor (T7) is connected to an anode of an organic light-emitting diode (OLED), such that when the organic light-emitting diode (OLED) is in a light-emitting state, a current, which leaks from the anode of the organic light-emitting diode (OLED) by means of the anode reset transistor (T7), is collected at the output end of the driving transistor (T1), and part of the current, which is collected at the output end of the driving transistor (T1), is transmitted to the anode of the organic light-emitting diode (OLED).
