ARRAY SUBSTRATE AND DRIVING METHOD THEREOF, AND DISPLAY DEVICE

Title:

ARRAY SUBSTRATE AND DRIVING METHOD THEREOF, AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/233549

Kind Code:

A1

Abstract:

An array substrate and a driving method thereof, and a display device. When the array substrate is driven, each data line D1 is enabled to provide data signals with continuously changing polarities for a column of pixel units (10), and two adjacent data lines D1 provide data signals with the same polarity at the same time. Because the two adjacent pixel units (10) located in the same row are connected to different gate lines G1, the two adjacent pixel units (10) located in the same row can be opened at different time; furthermore, the two adjacent data lines D1 provide the data signals for the two adjacent pixel units (10) in the same row at different time, the polarities of the data signals provided for the two adjacent pixel units (10) in the same row are ensured to be opposite, and a requirement of enabling the polarities of the data signals loaded to the two adjacent pixel units (10) to be opposite is satisfied. Because polarity change directions of the data signals provided by the adjacent data lines D1 in the same period of time are the same, a common electrode potential can be pulled up or pulled down at the same time, a potential difference between a common electrode and a pixel electrode is reduced, and the charging efficiency is improved.
