Problems solved by technology

[0004] However, in the method of fabricating the touch electrodes on the flexible substrate of PI material, the deformation rate of the metal part in the touch electrode is different from that of the organic material, and the deformation rate of the metal part is easy to occur during the use of the display device, especially the flexible display device. The problem of disconnection, which will adversely affect the touch performance

Embodiment Construction

[0026] The present application will be further elaborated below in conjunction with specific embodiments. It should be understood that these examples are only used to illustrate the present application and are not intended to limit the scope of the present application.

[0027] In order to illustrate the technical effects of the embodiments of the present invention more clearly, before describing the embodiments of the present invention, the discovery of the technical problems will be described first. In the prior art, the touch electrodes are made on the flexible substrate of PI material, and the metal part of the touch electrode is adjacent to the flexible substrate. In folded or curled display devices, the touch performance is adversely affected. On this basis, the inventors further found that the metal part is prone to disconnection related to the manufacturing process, such as figure 1 as shown, figure 1 It is a schematic diagram of the cross-sectional structure of the ...

Abstract

The invention relates to the field of touch control, and particularly to a touch panel, a touch display device and a manufacture method thereof, which can reduce occurrence probability of line disconnection of a metal portion, and thus improve touch performance. A touch film layer includes a flexible substrate and a metal layer. Material of the flexible substrate is polyimide. An organic film layer is disposed between the metal layer and the flexible substrate. A water droplet contact angle of the organic film layer is less than 80 degrees. The touch film layer also includes a touch electrodelayer. The touch electrode layer includes multiple groups of first touch electrodes and multiple groups of second touch electrodes. Each group of the first touch electrodes includes multiple first touch electrodes arranged in a second direction. Each group of the second touch electrodes includes multiple second touch electrodes arranged in a first direction. The metal layer includes metal connection lines. In each group of the first touch electrodes, the adjacent first touch electrodes are electrically connected through metal connection lines.

Description

technical field [0001] The present invention relates to the field of touch control, in particular to a touch film layer, a touch panel and a touch display device thereof. Background technique [0002] In recent years, touch sensing technology has been continuously developed, and touch panels (Touch Panels) are installed on mobile phones, tablet computers and many other display devices. Currently common touch panels include resistive, capacitive and optical. In the prior art, the touch sensing electrodes and touch driving electrodes in the mutual capacitive touch structure using indium tin oxide (ITO) materials are arranged on the same layer, and the touch electrodes in the same row or column need to use metal bridges. The structure is electrically connected. At the same time, because the metal grid has the advantages of high conductivity and low price, it can be used as an alternative to the touch electrode made of indium tin oxide. [0003] In order to overcome this defe...
