Title:
DISPLAY SUBSTRATE, DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/228411
Kind Code:
A1
Abstract:
A display substrate, a driving method therefor, and a display device. The display substrate comprises a display region and a non-display region surrounding the display region. The display region comprises multiple gate lines (Gate1, Gate2, and so on) and multiple data lines. The multiple gate lines (Gate1, Gate2, and so on) and the multiple data lines define multiple pixel units, and each pixel circuit is connected to a gate line and a data line. The non-display region comprises a source driving circuit (1), a compensation turn-on circuit (2), and a voltage compensation circuit (3). The source driving circuit (1) is configured to provide data signals to the multiple data lines. The compensation turn-on circuit (2) is configured to write turn-on signals into the multiple gate lines (Gate1, Gate2, and so on) when the display substrate displays a grayscale image or a flickering image. The voltage compensation circuit (3) is configured to perform at least one of the following functions: writing compensation signals into the multiple data lines when the display substrate displays a grayscale image; and writing compensation signals into data lines in odd columns or data lines in even columns when the display substrate displays a flickering image.
