Title:
PIXEL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/103053
Kind Code:
A1
Abstract:
A pixel circuit (100), comprising a switch circuit (110), a storage circuit (120), a drive circuit (130), and a pull-down circuit (140). The switch circuit (110) is configured to provide a first power supply signal and a second power supply signal for the storage circuit (120) according to a first gate drive signal; the storage circuit (120) is configured to provide a corresponding one of a first data signal and a second data signal for a first node (N1) in response to one of the first power supply signal and the second power supply signal; the drive circuit (130) is configured to write a voltage signal of the first node (N1) to a pixel electrode (150) according to a second gate drive signal. The circuit structure of the pixel circuit (100) is relatively simple, and there are a few used transistors, so that the occupied area is relatively small, and a high-resolution display device can be realized.
