Embodiment 1

[0026] see figure 1 The touch display device 10 provided in this embodiment includes a touch structure 20 and a display panel 30 , and further includes a cover plate 50 located on a side of the touch structure 20 away from the display panel 30 . Wherein, in this embodiment, the touch structure 20 is stacked and disposed with the display panel 30 as a structure independent of the display panel 30 . In other embodiments, the touch structure 20 may be embedded in the display panel 30 , which is not correct in the embodiment of the present invention. The touch structure 20 and the structure of the display panel 30 are defined. The touch structure 20 is used for touch operation, the display panel 30 is used for image display, the surface 51 of the cover plate 50 away from the touch structure 20 is used as a touch surface during touch operation, and the surface 51 is also used for displaying the display panel 30 displayed images. The touch display device 10 provided in this embodi...

Embodiment 2

[0042] see Figure 5 The main difference between the touch control structure 40 provided in this embodiment and the first embodiment is that the second extending portion 432 is a double-layer structure of transparent conductive material and metal. Only the above differences will be described in detail below:

[0043] see Image 6 The second extension portion 432 of the electrical connection line 43 includes a stacked metal layer 4321 and a transparent conductive layer 4322 , wherein the transparent conductive layer 4322 is located between the substrate 41 and the metal layer 4321 . In this embodiment, the transparent conductive layer 4322 is made of the same material as the first extension portion 431 and the touch electrode 42 , which is indium tin oxide; the metal layer 4321 is copper.

[0044] The following will Image 6 The manufacturing process of the middle touch structure 40 is described as follows:

[0045] see Figure 7 , a base material 45 is formed on the subst...

Abstract

The present invention provides a touch control structure, comprising: a substrate defining a touch area and a non-touch area adjacent to the touch area; a plurality of touch electrodes disposed on the substrate and is located in the touch control area; a plurality of electrical connection lines are formed on the substrate and electrically connected to the plurality of touch electrodes respectively, and each electrical connection line includes a first extension part located in the touch control area and a second extension portion located in the non-touch area and electrically connected to the first extension portion, the first extension portion of each electrical connection line is made of transparent conductive material; and a driver, the driver is connected to the plurality of The electrical connection lines are electrically connected, and are used for driving the plurality of touch electrodes through the plurality of electrical connection lines to realize touch operation. The present invention also provides a touch display device.

Description

technical field [0001] The present invention relates to the technical field of display touch control, and in particular, to a touch control structure and a touch display device including the touch control structure. Background technique [0002] Traditional smart devices usually have a touch control structure, which is used as a medium for human-computer interaction. The touch control structure is usually used with a display panel, and the display panel has a display area capable of displaying images and a non-display area surrounding the display area and not used for displaying images. The touch control structure is provided with touch electrodes at positions corresponding to the display area, and structures such as wirings, drivers, etc. are provided at positions corresponding to the non-display area. As the requirements for the narrow frame of the touch structure (usually the area where the traces and drivers are set are defined as the frame area of ​​the touch structure...
