AI Technical Summary

Problems solved by technology

The display accuracy of this product is not high enough, and the blackness of the display area is not deep enough when the screen is black, and there is a phenomenon of whitening
Moreover, due to the reflection of ambient light by the air layer in the internal structure, the display accuracy of these touch screens is not high enough, and the mimicry is not realistic enough, especially when the screen is black, the black border of the silk screen and the black screen have obvious color difference

preparation example Construction

[0026] Such as figure 2 As shown, the present invention also discloses a method for preparing a mimic touch screen, comprising the following steps:

[0027] (1) Paste the adhesive surface of the second polarizer on the lower surface of the liquid crystal glass by laminating instrument or manually;

[0028] (2) paste the nano-touch layer on the non-adhesive surface of the first polarizer; paste the adhesive surface of the first polarizer on the back of the transparent substrate; when pasting the nano-touch layer, manually or by machine To stick the film, the film sticking method is carried out by wet sticking or dry sticking;

[0029] (3) Then fix the transparent substrate and liquid crystal glass, and the transparent substrate and liquid crystal glass are fixed together by foam double-sided adhesive, or fixed by a frame, and the frame material can be selected according to the actual application. Different materials, such as aluminum alloy material;

[0030] (4) In step (3)...

Embodiment 1

[0035] Use this preparation method to prepare a 22-inch touch screen, and its preparation method is as follows:

[0036] (1) Cut out the second polarizer of 22 inches, place it on the bonding machine, and paste the second polarizer on the lower surface of the 22-inch liquid crystal glass by the machine;

[0037] (2) Paste the first polarizer of the same size on the lower surface of the 22-inch transparent substrate by a bonding machine, and then paste the 22-inch nano-touch layer on the outside of the first polarizer in turn;

[0038] (3) Fix the aluminum alloy frame around the liquid crystal glass, and finally fix the tempered glass with the first polarizer and the nano-touch layer on the liquid crystal glass, because the aluminum alloy frame causes the gap between the transparent substrate and the liquid crystal screen There is a 1mm thick distance, which is the air layer, and finally fix other parts.

Embodiment 2

[0040] (1) Spray the cleaning solution diluted 20 times with water on the lower surface of the 43-inch liquid crystal glass, and stick the second polarizer after aligning the position, scrape off the excess cleaning solution by hand with a scraper, and stick the polarizer after natural drying joined to the glass;

[0041] (2) stick a 3mm thick transparent interlayer on the upper surface of 43 cun liquid crystal glass, present embodiment selects transparent PMMA plate (being commonly called as plexiglass);

[0042] (2) Spray the diluted washing liquid on the lower surface of the transparent substrate, paste the first polarizer, scrape off the excess washing liquid with a scraper manually, and spray the diluted washing liquid on the outside of the first polarizer after it dries. After the final washing liquid, paste the nano-touch layer, scrape off the excess washing liquid with a scraper, and dry the transparent substrate with the nano-touch layer and the first polarizer;

Abstract

The invention discloses a mimetic touch screen which is composed of a transparent substrate, a first polarizing film, a nano touch layer, a separation layer, liquid crystal glass and a second polarizing film in sequence. The mimetic touch screen is placed perpendicular to the horizontal plane, the transparent substrate and the first polarizing film are sequentially located on the outer layer of the nano touch layer, and the separation layer, the liquid crystal glass and the second polarizing film are sequentially located on the inner layer of the nano touch layer. A preparation method of the mimetic touch screen comprises the steps that the back adhesive face of the second polarizing film is pasted on the lower surface of the liquid crystal glass; the nano touch layer is pasted on the non-back adhesive face of the first polarizing film; the back adhesive face of the first polarizing film is pasted on the back face of the transparent substrate; then the transparent base material and the liquid crystal glass are fixed; the separation layer is arranged between the transparent base material and the liquid crystal glass; after fixing is carried out, other parts and an outer frame are mounted and fixed, and the touch screen is manufactured. The internal structure of the touch screen is changed, the display blackness is increased, display precision is higher, and the display effect is more mimetic.

Description

technical field [0001] The invention relates to a mimetic touch screen and a preparation method thereof, belonging to the technical field of touch screens. Background technique [0002] As the latest computer input device, the touch screen is currently the simplest and most convenient way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. [0003] The structure of the projective touch screen currently used in the market is as follows from top to bottom: tempered glass-touch layer-air layer or transparent spacer-polarizer-liquid crystal glass-polarizer. The display accuracy of this product is not high enough, and when the screen is black, the blackness of the display area is not deep enough, and there is a phenomenon of whitening. Moreover, due to the reflection of ambient light by the air layer in the internal structure, the display accuracy of these touch screens is not high enough, and the mimic...
