Problems solved by technology

At present, in the manufacturing process of the touch structure for flexible display products, the more mainstream roll-to-roll (roll-to-roll) process is adopted, and the functional layers for signal transmission are respectively arranged on both sides of the film substrate, which makes The stresses on the functional layers are different during bending, which makes the products manufactured by the Roll To Roll process easy to break when dealing with small curvature radii, which may not meet the design requirements of small curvature or folding products

preparation example Construction

[0059] At least one embodiment of the present disclosure provides a method for manufacturing a touch structure, including: providing a film substrate; providing a base substrate, and attaching the film substrate to the base substrate; A stacked structure for realizing the touch function; and removing the film substrate on which the stacked structure is formed from the base substrate. At least one embodiment of the present disclosure further provides a touch control structure and a display device corresponding to the above-mentioned manufacturing method of the touch control structure.

[0060] The preparation method of the touch structure can make the functional layer of the touch structure distributed on the same side of the film substrate, and the stress is the same when it is bent, so that the risk of fracture can be reduced, and the preparation method can also improve the alignment accuracy.

[0061] In an embodiment of the present disclosure, the patterning process may be ...

Embodiment 1

[0064] An example of this embodiment provides a touch structure, such as Figure 3A As shown, the touch structure 10 can be divided into a touch area 101 and a non-touch area 102 (for example, a peripheral area). For example, the touch area 101 is an area where touch electrodes are disposed, and the non-touch area 102 is an area where wires (such as metal wires) connected to the touch electrodes are disposed.

[0065] For example, also as figure 1 and figure 2 As shown, the touch structure 10 includes: a film substrate 100 ; a first conductive layer 200 disposed on the film substrate 100 ; and an alignment mark 500 disposed on the first conductive layer 200 for realizing the alignment function.

[0066] For example, the film substrate 100 adopts a film material with high transmittance, especially a film material with flexibility. For example, the film substrate 100 may be a cycloolefin polymer (COP) film or a polyimide (PI) film or the like. For another example, when the ...

Embodiment 2

[0099] This embodiment provides a display device, including the touch structure described in any one of the first embodiment.

[0100] The display device provided in this embodiment may also include a display screen. It should be noted that this embodiment does not limit the combination of the touch structure and the display screen.

[0101] For example, the display screen includes an array substrate and an opposite substrate (such as a color filter substrate) that is boxed with the array substrate.

[0102] For example, the touch control structure may be disposed on a protective cover, and the protective cover is used to cover the display screen to protect the display screen, and the side of the protective cover formed with the touch control structure faces the display screen. That is, the combination method of the touch structure and the display screen is an OGS (One Glass Solution) method.

[0103] For another example, the touch control structure may be disposed on a side...

Abstract

The invention relates to a touch control structure and a preparation method thereof, and a display device. The preparation method of the touch control structure comprises the following steps of: providing a thin film substrate; a substrate is provided and that thin film substrate is adhered on the substrate; forming a laminated structure for realizing a touch function on the thin film substrate; removing the thin film substrate on which the laminated structure is formed from the substrate substrate. The preparation method of the touch control structure can make the functional layer of the touch control structure distribute on the same side of the film substrate, and the stress is the same when the film substrate is bent, so that the fracture risk can be reduced, and meanwhile, the preparation method can improve the alignment accuracy.

Description

technical field [0001] Embodiments of the present disclosure relate to a touch control structure, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, the rapid development of flexible display technology has provided manufacturers with a lot of room for innovation. When applying flexible display products to high-end mobile phones or new-generation wearable display devices, the products are required to have touch functions at the same time. At present, in the manufacturing process of the touch structure for flexible display products, the more mainstream roll-to-roll (roll-to-roll) process is adopted, and the functional layers for signal transmission are respectively arranged on both sides of the film substrate, which makes The stress on the functional layer is different when it is bent, so that the products manufactured by the Roll To Roll process are prone to fracture when dealing with small curvature radii, which may not meet...
