PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/227788
Kind Code:
A1
Abstract:
A pixel driving circuit and a driving method therefor, and a display panel. The pixel driving circuit comprises a data write circuit (1), a driving circuit (2), a light-emission control circuit (3), a compensation circuit (4) and a storage circuit (5), wherein the data write circuit (1) is coupled to the driving circuit (2) and is used for writing a data signal into the driving circuit (2); the driving circuit (2) is coupled to a first power source end (VDD) and a light-emitting unit (6) by means of the light-emission control circuit (3), and is used for inputting, under the control of the light-emission control circuit (3), a driving current into the light-emitting unit (6) according to the data signal; the compensation circuit (4) is coupled to the driving circuit (2); the storage circuit (5) is coupled between the first power source end (VDD) and the driving circuit (2); and the data write circuit (1) and the compensation circuit (4) comprise at least two transistors, wherein in the data write circuit (1) and the compensation circuit (4), at least one transistor is a low-temperature polysilicon transistor, and at least one transistor is an oxide transistor.
