Abstract

The invention discloses a touch screen, a method for manufacturing the same and a display device. The touch screen comprises a plurality of first transparent electrodes, a plurality of second transparent electrodes, first conducting layers and / or second conducting layers; the first transparent electrodes are arranged on a substrate and extend along a first direction, and the second transparent electrodes extend along a second direction which is intersected with the first direction; the first conducting layers are positioned on at least one sides of the first transparent electrodes and are connected with the first transparent electrodes in parallel; the second conducting layers are positioned on at least one sides of the second transparent electrodes and are connected with the second transparent electrodes in parallel; the first conducting layers and the second conducting layers are metal layers or alloy layers. The touch screen, the method and the display device have the advantage that the touch screen is excellent in touch effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch screen, a manufacturing method thereof, and a display device. Background technique [0002] In the field of display technology, a touch screen, as a new input device, has been more and more widely used in the field of touch display technology. [0003] Classified by touch input methods, touch screens include resistive, capacitive, optical, acoustic, electromagnetic, and so on. Among them, the capacitive touch panel has the advantages of fast response time, high reliability and high durability. According to the way of integration with display devices, touch screens include at least two types: in-cell (In Cell) and add-on (Add on). [0004] Generally, the structure of the touch screen is to fabricate touch driving electrodes and touch sensing electrodes to realize the touch function in the touch area of ​​the substrate. At present, the multi-touch touch screen is based ...
