Title:
DISPLAY PANEL AND LIGHT EMISSION CONTROL CIRCUIT THEREOF, DRIVING METHOD, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/155975
Kind Code:
A1
Abstract:
A light emission control circuit of a display panel, a display device, and a driving method. The display panel comprises: multiple rows of sub-pixels (01), each row of sub-pixels (01) comprising at least a first color sub-pixel (01a) and a second color sub-pixel (01b), the first color sub-pixel (01a) and the second color sub-pixel (01b) both comprising a pixel circuit (011) and a light emission unit (012); and a light emission control circuit (02) comprising multiple light emission control circuit groups (021) corresponding one-to-one to the multiple rows of sub-pixels (01), and each light emission control circuit group (021) at least comprising a first light emission control sub-circuit (0211) and a second light emission control sub-circuit (0212); the first light emission control sub-circuit (0211) and the second light emission control sub-circuit (0212) are respectively connected to the pixel circuit of the first color sub-pixel (01a) and the pixel circuit of the second color sub-pixel (01b) in one row of sub-pixels (10) and provide a first light emission control signal (EM1) and a second light emission control signal (EM2) respectively; and the first light emission control signal (EM1) and the second light emission control signal (EM2) are respectively configured to drive the pixel circuits to output driving currents to the light emission units.
