Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/085490
Kind Code:
A1
Abstract:
Disclosed are a pixel circuit and a driving method therefor, and a display apparatus. The pixel circuit comprises a first thin-film transistor, a second thin-film transistor, a third thin-film transistor, a fourth thin-film transistor, a fifth thin-film transistor, a sixth thin-film transistor, a seventh thin-film transistor, a light-emitting diode and a storage capacitor. According to the pixel circuit provided in the embodiments of the present application, at a light-emitting stage of the light-emitting diode, a power supply voltage can be compensated for, so that the current flowing through the light-emitting diode is related to a data voltage input to the pixel circuit and a reference voltage, but is unrelated to the power supply voltage, thus effectively avoiding the problem of the display of the display apparatus being non-uniform due to the difference, caused by a power supply voltage drop, of the currents flowing through each light-emitting diode.
