Embodiment Construction

[0031] The specific implementation manners of a touch screen provided by the embodiments of the present invention, a manufacturing method thereof, and a display device will be described in detail below with reference to the accompanying drawings.

[0032] The shape and thickness of each film layer in the drawings do not reflect their true proportions, and the purpose is only to illustrate the content of the present invention.

[0033] A method for manufacturing a touch screen provided by an embodiment of the present invention, such as figure 1 shown, including the following steps:

[0034] S101, forming a pattern including touch electrodes on the light emitting side of the display panel after the cell alignment process;

[0035] Specifically, a transparent conductive oxide material such as Indium Tin Oxide (ITO) is generally used to form the pattern of the touch electrode by a patterning process. First, a layer of ITO film is deposited on the light-emitting side of the displa...

Abstract

The invention discloses a touch screen, a manufacturing method thereof and a display device. in a manufacturing process of the touch screen, after patterns of touch electrodes are formed on a light exiting side of a display panel by using a box technology, an organic transparent insulating layer of which the refractive index is similar to that of the touch electrodes is formed on a display panel with the patterns of the touch electrodes in a coating mode; because the refractive index of the organic transparent insulating layer is similar to that of the touch electrodes, the optical path difference of light in a region corresponding to the patterns of the touch electrode and a region without the patterns of the touch electrodes is small, the difference of the light transmissivity is small, and disapparate and white stripes of the touch screen can be avoided without the aid of disapparate glass; the organic transparent insulating layer is formed in the coating mode, and the problem that the touch screen is damaged by a high-temperature environment is solved; and moreover, the organic transparent insulating layer is formed after the touch electrodes are formed, and electrodeposition equipment for the touch electrodes is prevented from being polluted by the organic transparent insulating layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch screen, a manufacturing method thereof and a display device. Background technique [0002] According to the composition and structure, the touch screen can be divided into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel. Among them, the overlay touch screen is to arrange the touch electrodes of the touch screen between the opposite substrate of the display screen and the polarizer, which has a high yield and does not reduce the area of ​​the display area. [0003] In existing surface-covered touch screens, transparent conductive oxide materials such as Indium Tin Oxide (ITO) are generally used to form touch electrodes on the glass substrate on the light emitting side of the touch screen. Due to the large difference between the refractive index of ITO and the refractive index of the glass substrate, when the touch screen is not lit, the external na...
