Title:
DISPLAY PANEL AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/078150
Kind Code:
A1
Abstract:
A display panel and an electronic device. When locally refreshing, the problem of waveform loss between rows can be solved. The display panel comprises a cascaded scanning drive unit (ASG1). The scanning drive unit (ASG1) comprises a shift module (142a), which receives a shift signal from a trigger signal input terminal (IN), a first level signal received by a first level signal receiving terminal (VGL), a second level signal received by a second level signal receiving terminal (VGH), a first clock signal received by a first clock signal terminal (CK1), and a second clock signal received by a second clock signal terminal (CK2), and controls a signal of a first node (N1) in response to the first level signal, the first clock signal, and the second clock signal; a gating logic module (142b), which receives the first level signal and the second level signal, and controls a signal of a second node (N2) in response to the signal at the first node (N1) and an area gating signal received by an area gating control terminal (CK3); and an output module (142c), which receives the first level signal or the second level signal, and in response to the signal of the second node (N2), controls a signal outputted by a drive signal output terminal (OUT).
