Description

Single-film touch screen

Technical Field

The utility model relates to a single membrane touch screen.

Background

At present, all large-size touch screen touch realization modes are generally GLASS or double-FILM, the thickness of a product is increased by using GLASS, and the material cost is increased by using double-FILM. So for a more adaptable thinner solution on the market. Both structures are not suitable for thin and light products due to structural limitations.

This patent adopts single membrane touch-control mode, uses this patent can bring more frivolous experience for the product.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a single membrane touch screen, single membrane structure is done the TX of touch-control on the FILM, is done touch-control RX on the CG apron to realize the touch-control of a few tunic.

The utility model adopts the following technical scheme: a single-FILM touch screen comprises a CG glass cover plate, an OCA optical cement and a TX FILM, wherein the CG glass cover plate is bonded on the TX FILM through the OCA optical cement, and an RX is arranged on a bonding surface of the CG glass cover plate.

And the TX FILM is used for making touch TX on the FILM.

The four corners of the TX FILM are circular arcs with the radius of 29 mm.

The panel of the TX FILM is printed with black by silk screen, and the thickness of the printing ink is less than 15 mm.

The length and width of the CG glass cover plate are smaller than those of the TX FILM, and a distance of 29mm is reserved.

The CG glass apron will be done the preliminary treatment, and the preliminary treatment includes that AG prevents dazzling membrane processing and AF prevents fingerprint oil nanometer coating, and AG prevents dazzling membrane processing and can prevent that light from directly penetrating into eyes to effectively reduce glare and reflection, improve LCD's display effect.

And finally, carrying out chemical strengthening on the product.

The utility model discloses the principle: the principle of the touch screen is that a finger of a person passes through the touch screen, the finger and the screen form a capacitor, the human body is connected with the ground, the finger can absorb charges on the screen body and transfer the charges to the ground, the local charges of the touch screen body are reduced, the charges are supplemented from the periphery, and the screen body is scanned by RX and TX to the screen body, so that an IC calculates a coordinate point. The screen body is mainly two TX and RX acting. Glass sensor is made by putting TX and RX on the Glass square. Dual FILM touch is performed with one TX and one RX per FILM layer. Thus, the CG glass cover is not used at all, so the patent uses the binding surface of CG. And (3) making TX on a binding surface of the CG and making RX by using a single film so as to form a touch mode.

The utility model has the advantages that: the thickness of the obtained final product is 1.8 +/-0.2 mm, the final product is thinner than a glass sensor, the process is simpler, and a layer of FILM is obviously reduced compared with a double-FILM sensor, so that the material cost is saved. The utility model discloses can be applied to super large-size touch-sensitive screen, meeting all-in-one, intelligent blackboard, adopt single membrane touch-control mode, bring more frivolous experience for the product.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

The utility model provides a single FILM touch screen, includes CG glass apron 1, OCA optical cement 2 and TX FILM 3, and CG glass apron 1 bonds on TX FILM 3 through OCA optical cement 2, and the binding face of CG glass apron 1 is equipped with RX.

The TX FILM 3 is used for making touch TX on a FILM.

Four corners of the TX FILM 3 are arcs with the radius of 29mm

The panel of the TX FILM 3 is printed with black by silk screen, and the thickness of the printing ink is less than 15 mm.

The length and width of the CG glass cover plate 1 are smaller than those of the TX FILM 3, and a distance of 29mm is reserved.

CG glass apron 1 will do the preliminary treatment, and the preliminary treatment includes that AG prevents dazzling membrane processing and AF prevent fingerprint oil nanometer coating, and AG prevents dazzling membrane processing and can prevent that light from directly penetrating into eyes to effectively reduce glare and reflection, improve LCD's display effect.

And finally, carrying out chemical strengthening on the product.

The utility model discloses the principle: the principle of the touch screen is that a finger of a person passes through the touch screen, the finger and the screen form a capacitor, the human body is connected with the ground, the finger can absorb charges on the screen body and transfer the charges to the ground, the local charges of the touch screen body are reduced, the charges are supplemented from the periphery, and the screen body is scanned by RX and TX to the screen body, so that an IC calculates a coordinate point. The screen body is mainly two TX and RX acting. Glass sensor is made by putting TX and RX on the Glass square. Dual FILM touch is performed with one TX and one RX per FILM layer. Thus, the CG glass cover plate 1 is not used at all, so the patent uses the contact surface of CG. And (3) making TX on a binding surface of the CG and making RX by using a single film so as to form a touch mode.

The CG glass cover plate 1 and the TX FILM 3 are both made of Lens materials and are made of tempered glass. The test shows that the single-film structure has the transmittance of more than 88 percent and the surface hardness of more than or equal to 7H (1 kg force); the steel ball with the falling ball strength of 261g falls from 80cm at 5 points, each point is 3 times, and the single-film structure is not broken; after chemical strengthening, the warping degree of the long side is less than or equal to 0.1 percent, CS is more than 450MPa, and DOL is more than or equal to 8 um.

Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
