Abstract

The invention discloses a touch screen and a display device. The touch screen comprises first strip electrodes and second strip electrodes, which are arranged in different layers in a cross manner, wherein the side edges, located at the two sides of the extension direction, of each first strip electrode located on the upper layer of the corresponding second strip electrode are provided with wavy structures, and an included angle between each of all fold line segments forming the wavy structures and the extension direction of the first strip electrodes is an acute angle; in a touch control time period, the first strip electrodes are used for loading touch control scanning signals, and the second strip electrodes are used for coupling voltage signals of the touch control scanning signals and outputting the voltage signals; or the second strip electrodes are used for loading the touch control scanning signals, and the first strip electrodes are used for coupling the voltage signals of the touch control scanning signals and outputting the voltage signals. The side edges, at the two sides of the extension direction, of each first strip electrode are provided with the wavy structures, so that Moire patterns resulting from interference of light caused by regular patterns of the edges of the first strip electrodes can be reduced, then, the visibility of the Moire patterns on the surface of the touch screen is eliminated, and the quality of display of the touch screen is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch screen and a display device. Background technique [0002] At present, the existing capacitive touch screen uses the principle of mutual capacitance to detect the touch position of a finger; wherein, generally, a pattern of a touch structure is added to the touch screen. Specifically, the pattern of the touch structure generally includes a plurality of strip-shaped transparent touch driving electrodes and a plurality of strip-shaped transparent touch sensing electrodes arranged in different layers and intersecting each other, wherein the two layers of transparent electrodes in the touch structure The strip electrodes in the upper layer of the structure tend to produce light interference with the regular pattern in the pixel structure of the touch screen, such as the pattern of the black matrix layer, causing moiré, thereby affecting the display quality of the touch scree...
