Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/052287
Kind Code:
A1
Abstract:
A pixel circuit and a driving method therefor, and a display device. A pixel circuit (100) comprises: a storage circuit (11), a data write circuit (12), a light-emitting driver circuit (13), and a compensation circuit (14). The data write circuit (12) is connected to the storage circuit (11), and is configured to write a data voltage into the storage circuit (11) under the control of a scanning control signal. The storage circuit (11) is configured to store the data voltage and make the stored data voltage used for compensating by the compensation circuit (14). The compensation circuit (14) is connected to the light-emitting driver circuit (13), and is configured to maintain the stored data voltage-based compensation voltage at a control end of the light-emitting driver circuit (13) under the control of a compensation control signal. The light-emitting driver circuit (13) is further connected to a light-emitting element (EL), and is configured to drive the light-emitting element (EL) to emit light under the control of the compensation voltage.
