Abstract

A display substrate and a display device are provided. The display substrate has a display area and a peripheral area surrounding the display area. The display substrate includes a first common voltage line, a second common voltage line and an integrated circuit. The first common voltage line is provided in the peripheral area and at least partially surrounds the display area; the second common voltage line is provided in the peripheral area, located on a side of the first common voltage line away from the display area, and at least partially surrounds the display area; the integrated circuit is provided in the peripheral area, and located on a first side of the display area, configured to provide first signals to the first and second common voltage line during a display stage, and provide second signals to the first and second common voltage line during a touch stage.

Claims20

Dependent claims

A display substrate having a display area and a peripheral area surrounding the display area, and having a touch function, the display substrate comprising:

a first common voltage line at least partially provided in the peripheral area and at least partially surrounding the display area;
a second common voltage line at least partially provided in the peripheral area, the second common voltage line being located on a side of the first common voltage line away from the display area and at least partially surrounding the display area;
and
a peripheral circuit at least partially provided in the peripheral area, the peripheral circuit being located at a first side of the display area and configured to provide first signals identical to display signals to the first common voltage line and the second common voltage line during a display stage, and provide second signals identical to touch signals to the first common voltage line and the second common voltage line during a touch stage,
wherein the first signals are different from the second signals.
