Problems solved by technology

In the prior art, since the commonly used glass substrate is difficult to meet the requirements of the touch sensor substrate of the curved touch screen, a flexible film is generally used, such as a PET film as the base material to make a bendable touch screen, and then bonded and fixed to the curved cover plate
However, conventional bendable touch screens made of flexible films may suffer from iridescence problems or be limited by reliability.

other Embodiment approach

[0084] In other implementation manners, the providing a glass substrate with touch electrodes on its surface includes: directly using a glass substrate with a thickness smaller than the preset threshold to directly form touch electrodes on its surface.

other Embodiment approach

[0085] In other implementation manners, the providing the glass substrate with touch electrodes on the surface includes: providing the glass substrate with a first thickness, and the first thickness is greater than the preset threshold; The two surfaces are thinned so that the thickness of the substrate is less than the preset threshold; the touch electrodes are formed on the first surface of the glass substrate. In this way, the glass substrate is thinned before the touch electrodes are formed. Two glass substrates can be bonded to each other and thinned separately, or the glass substrate can be placed on a carrier substrate for thinning. For the method, reference may be made to the above-mentioned process, which will not be repeated here, and the glass substrate may also be directly thinned. In this way, the requirements for the thinning process are relatively high.

Abstract

The invention discloses a curved surface touch screen and a manufacturing method thereof. According to the technical scheme, a glass substrate is adopted as a base material of a touch control electrode, when the thickness of the thinned glass substrate is smaller than a preset threshold value, the bending requirement can be met, and then the glass substrate can be fixedly fitted with a curved surface cover plate. Compared with an existing mode of adopting flexible thin film, a glass material has the advantages that the glass substrate is fixedly fitted with the curved surface cover plate, theoptical reliability is good, and the problem of rainbow stripes can be avoided.

Description

technical field [0001] The present invention relates to the technical field of touch devices, and more specifically, to a curved touch screen and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with touch function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become the Indispensable and important tool. [0003] The main component of the electronic device to realize the touch function is the touch screen. At present, the curved touch screen has become one of the representatives of the high-end touch screen. In the prior art, since the commonly used glass substrate is difficult to meet the requirements of the touch sensor substrate of the curved touch screen, a flexible film is generally used, such as a PET film as the base material to make a bendable touch screen, and then bonded and fixed to the...
