Embodiment Construction

[0026] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] An embodiment of the present invention provides a display substrate. The display substrate includes a display area and a frame area. The display area can be divided into multiple touch areas. Such as figure 2 , The display substrate includes 12 rows of touch electrodes for providing touch detection signals in one...

Abstract

The invention provides a display substrate as well as a drive method thereof and a display device. The display substrate comprises a touch area, wherein a plurality of rows of touch electrodes are arranged in the touch area; touch controller electrodes in each row of touch electrodes are connected with each other; on a touch detecting stage, each row of touch electrodes in the touch area is independent with one another; and on a display stage, each row of touch electrodes in the touch area is connected together as a public electrode. In this way, on the display stage, voltage difference between public voltage provided by the touch electrodes at one side far away from a drive circuit and the public voltage output by the drive circuit is greatly reduced, so that the public voltage provided by public electrodes is almost consistent, and an uneven display brightness problem can be avoided.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a driving method thereof, and a display device. Background technique [0002] Due to the ease of use, versatility of operation, declining prices and steadily increasing yield of touch screens, they are becoming more and more popular. The touch screen can be divided into plug-in type and in-line type according to its setting position. The plug-in type can position the panel with touch function in front of the display, and the touch surface covers the visible area of ​​the display area to realize touch. Built-in, the touch function is integrated on the panel, and a protective glass is attached to the outside. The user can operate by touching the screen with his finger. [0003] In order to further reduce the complexity of the manufacturing process and the thickness of the display panel, a display substrate in which common electrodes are reused as touch elect...
