Abstract
A touch screen and a display device are provided. The touch screen includes first strip electrodes and second strip electrodes, which are disposed in different layers and intersect with each other. The first strip electrodes disposed in a layer above the second strip electrodes have patterns to prevent Moire fringes caused by interference. In the touch period at least some of the first strip electrodes are configured to load touch scanning signals while the second strip electrodes are configured to couple with the voltage signals of the touch scanning signals and output signals; or in the touch period the second strip electrodes are configured to bad touch scanning signals while at least some of the first strip electrodes are configured to couple with the voltage signals of the touch scanning signals and output signals. The touch screen can reduce Moire fringes at the edges of the first strip electrodes caused by interference of light due to regular patterns.
