Embodiment Construction

[0032] The specific implementation manners of the touch screen and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] The thickness and shape of each film layer in the drawings do not reflect the real scale, and the purpose is only to illustrate the content of the present invention.

[0034] A touch screen provided by an embodiment of the present invention includes: a first strip-shaped electrode, a second strip-shaped electrode that intersects with the first strip-shaped electrode and is located on the lower layer of the first strip-shaped electrode. The extension direction of the electrode is the vertical direction, and the extension direction of the second strip electrode is the horizontal direction as an example for illustration; wherein,

[0035] The first strip electrode has a pattern that prevents interference from causing moiré;

[0036] During the touch contro...

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 first strip electrodes located on upper layers of the second strip electrodes are provided with patterns which are used for preventing the generation of interference caused Moire patterns; in a touch control time period, at least part of 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 in the touch control time period, the second strip electrodes are used for loading the touch control scanning signals, and at least part of the first strip electrodes are used for coupling the voltage signals of the touch control scanning signals and outputting the voltage signals. The first strip electrodes are provided with the patterns which are used for preventing the generation of the interference caused Moire patterns, 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...
