Problems solved by technology

[0003] However, it is difficult to process and cut large pieces of glass after strengthening treatment, so the final step of the above-mentioned manufacturing process (that is, the step of cutting the large piece of glass into small pieces of glass) is difficult to realize, which in turn makes it difficult to use this method to make touch screens.

Embodiment 1

[0065] The first embodiment of the present invention provides a manufacturing method of a touch screen, figure 1 Shows the flow chart of the production method, Figure 2a~2f Shows the structure diagram of each stage of the touch screen made by this method, and refer to figure 1 with Figure 2a~2f , The production method includes:

[0066] Step S101: Provide a glass plate 10, such as Figure 2a Shown

[0067] The glass plate 10 in the embodiment of the present invention generally needs to have higher transparency, lower reflectivity, better thermal stability and corrosion resistance, higher mechanical strength and mechanical processing characteristics.

[0068] The glass plate in the embodiment of the present invention may be glass that can be strengthened, such as borosilicate glass without alkali ions, alkali-free aluminum silicate glass, or aluminum silicate glass.

[0069] Step S102: Cut the glass plate 10 into a substrate 11 whose size meets predetermined requirements, such as Fig...

Embodiment 2

[0097] The second embodiment of the present invention provides a manufacturing method of a touch screen, Figure 4 Shows the flow chart of the production method, Figure 5a~5i The schematic diagrams of the various stages of manufacturing the touch screen using this method are shown. Compared with the first embodiment of the present invention, the detector layer 12 of the touch screen provided in the second embodiment of the present invention has a multilayer structure. Steps S401 to S403 are the same as steps S101 to S103 in the first embodiment. The structure diagrams of the touch screen at each stage of the production steps of step S403 to step S403 are shown in Figure 5a~5c (versus Figure 2a~2c Corresponding), for the sake of simplicity, the second embodiment of the present invention only introduces the differences from the first embodiment, and the similarities with the first embodiment can be learned by referring to the corresponding description in the first embodiment, whi...

Abstract

An embodiment of the invention provides a touch screen and a manufacturing method thereof. The manufacturing method includes providing a glass board; cutting the glass board into a substrate with the size meeting predetermined requirements; strengthening the substrate; manufacturing a detector layer on the strengthened substrate; manufacturing shading layers on regions outside a first predetermined region and a second predetermined region on the detector layer; manufacturing a first conductive layer on the first predetermined region of the detector layer; manufacturing a protective layer on the second predetermined region of the detector layer and enabling the protective layer to cover the parts of the shading layer; and manufacturing an FPC (flexible printed circuit) layer, enabling the FPC layer to cover the first conductive layer and electrically connecting the FPC layer with the detector layer via the first conductive layer. Compared with the prior art, the touch screen and the manufacturing method thereof are easy to implement.

Description

Technical field [0001] The present invention relates to the technical field of semiconductor manufacturing, in particular to a manufacturing method of a touch screen and a touch screen manufactured by the method. Background technique [0002] As handheld electronic devices continue to develop in the direction of miniaturization and thinning, touch screens used in these handheld electronic devices are required to become thinner and thinner. To meet this requirement, in the prior art, the touch screen is usually embedded in the glass cover. The manufacturing process of the touch screen generally adopts the following steps: firstly, a large piece of glass is strengthened, and then a series of operations such as shading layer printing, conductive layer production, and photolithography are performed on the strengthened glass, and finally the large piece of glass is cut into small pieces of glass . [0003] However, it is difficult to process and cut large pieces of glass after being s...
