Abstract

The present invention provides a gate drive circuit and a drive method thereof, and a display device. The gate drive circuit comprises: a plurality of scanning output ends; a serial data interface; aserial-to-parallel conversion circuit connected with the serial data interface and configured to receive serial data frames through the serial data interface and convert the serial data frames to parallel data frames; a latch circuit connected with the serial-to-parallel conversion circuit and configured to store and output the parallel data frames when any one data frame is completely received; and a decoder circuit connected with the latch circuit and each scanning output end and configured to output scanning signals at the scanning output ends corresponding to the data frames when the dataframes output by the latch circuit are received. The gate drive circuit and the drive method thereof, and the display device allow the gate drive circuit made on an array substrate to have a functionof flexibly selecting a pixel row to perform data refreshing.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to a gate driving circuit, a driving method thereof, and a display device. Background technique [0002] Compared with the traditional technology, the Gate driver On Array (GOA) technology can not only save the circuit board carrying the gate driver chip, realize the symmetrical design on both sides of the display panel, but also save the display panel edge. Die-bonding areas and routing areas such as fan-out areas facilitate the implementation of narrow bezel designs. However, the GOA circuit in the related design can only realize row-by-row data refresh of all pixel rows or a specific part of pixel rows, and cannot flexibly select pixel rows for data refresh. Contents of the invention [0003] The present disclosure provides a gate driving circuit, a driving method thereof, and a display device, which enable the gate driving circuit fabricated on an array substrate to have the ...
