Title:
PIXEL CIRCUIT AND CONTROL METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/253515
Kind Code:
A1
Abstract:
Disclosed are a pixel circuit and a control method therefor, and a display apparatus. The pixel circuit comprises a pixel drive circuit (110), a mode selection circuit (120, 120', 120") and a light-emitting device (130). The pixel drive circuit (110) is configured to output a drive current. The mode selection circuit (120, 120', 120") is used for choosing different light-emitting modes according to different mode selection signals (Smod). The light-emitting device (130) is used for emitting light with different brightness according to different light-emitting modes. The light-emitting device (130) comprises a first electrode structure (210), a second electrode structure (220) and a functional layer (230) between the first electrode structure (210) and the second electrode structure (220). The mode selection circuit (120, 120', 120") comprises a first switch sub-circuit (121, 121' 121") and a second switch sub-circuit (122, 122', 122"). The first switch sub-circuit (121, 121' 121") is configured to execute different first conduction modes in response to different mode selection signals (Smod). The second switch sub-circuit (122, 122', 122") is configured to execute different second conduction modes in response to different mode selection signals (Smod). The mode selection circuit (120, 120', 120") is configured to determine the light-emitting modes according to the first conduction modes and the second conduction modes.
