Title:
PIXEL CIRCUIT, ARRAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/051289
Kind Code:
A1
Abstract:
A pixel circuit (100), and an array substrate and a display device comprising the pixel circuit (100). The pixel circuit (100) comprises a driving circuit and a plurality of sub-pixels (103). The driving circuit comprises a conversion circuit (101) and one or more driving execution circuits (102). The conversion circuit (101) is used for receiving an image data signal in an analog form, and converting the image data signal in the analog form into an image data signal in a digital form. When the driving circuit comprises one driving execution circuit (102), the driving execution circuit (102) is electrically connected to the conversion circuit (101) and used for receiving the image data signal in the digital form and providing a driving current to the plurality of sub-pixels (103) in a time-sharing mode according to the image data signal in the digital form, to drive the plurality of sub-pixels (103) to perform image display. When the driving circuit comprises a plurality of driving execution circuits (102), the plurality of driving execution circuits (102) have one-to-one correspondence to the plurality of sub-pixels (103), and each driving execution circuit (102) is electrically connected between the conversion circuit (101) and the corresponding sub-pixel (103).
