Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0035] It should also be noted that the orientation terms such as left, right, up and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should not be regarded as re...

The invention provides a touch screen. The touch screen comprises a display module and a touch module, wherein the coverage area of the display module comprises a display area and a peripheral non-display area; the touch module comprises a first touch layer and a second touch layer, and a first insulating layer is clamped between the first touch layer and the second touch layer; the first touch layer comprises a first touch electrode arranged in the visible area, and a first metal lead and a second extending metal lead which are arranged in the non-visible area; the second touch layer comprises a second touch electrode arranged in the visible area and a second metal lead arranged in the non-visible area; in a coverage area where the non-display area and the projection of the touch module are overlapped, a first opening is formed in the first insulating layer, and a second metal lead is arranged on the second touch layer; and on the non-visual area, the second extension metal lead is electrically connected with the second metal lead through the first opening. According to the technical scheme, the second insulating layer between the second touch layer and the display module can be removed, so that the structure and the process of the touch screen are simpler and more reliable.
Description
technical field [0001] The invention belongs to the technical field of touch screens, in particular to a touch screen and a display device. Background technique [0002] At present, with the rapid development of display technology, touch screens have been widely used in various fields. The current common touch screen usually includes a touch module and a display module, wherein the touch module includes a substrate and two layers of touch layers arranged on the substrate, one of which is the first touch layer as the driving electrode layer, and the other One layer, the second touch layer, is the sensing electrode layer, and a first insulating layer needs to be provided between the two touch layers for protection and insulation. [0003] In the existing touch screen, since some other display devices generally need to be installed around the display module, it is necessary to reserve a space for the display device. It is necessary to add a bonding process of bonding the opti...
