Title:
DRIVE-SIGNAL OUTPUT CIRCUIT, SCREEN DRIVE CIRCUIT, DISPLAY SCREEN AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/007666
Kind Code:
A1
Abstract:
Provided in the present application are a drive-signal output circuit, a screen drive circuit, a display screen and an electronic device. The drive-signal output circuit comprises an N-type output circuit, wherein an input end of the N-type output circuit is coupled to a row scanning driver, a control end of the N-type output circuit inputs a row address selection signal, and an output end of the N-type output circuit is coupled to a horizontal scanning line. When the row address selection signal is valid, the N-type output circuit outputs a row scanning signal, so as to drive a corresponding pixel row to update corresponding content data. When a row address selection signal outputted by a DDIC is invalid, the N-type output circuit outputs an invalid signal. Instead of performing display content refreshing on the whole display screen all at the same refresh frequency, display content refreshing is respectively performed at different refresh frequencies on the basis of refresh requirements of different display regions on the display screen, thereby reducing the power consumption of the display screen.
