Description
Technical Field
The invention relates to a screen for an electronic product, in particular to a scratch-resistant projection type capacitive screen with a glass structure.
Background
At present, a projection type capacitive screen widely used for a touch screen in an electronic product mainly comprises a glass cover plate and a glass functional sheet, wherein SCA optical glue is adopted for adhering the glass cover plate and the glass functional sheet, ITO (indium Tin oxides) conducting layers are respectively arranged on two surfaces of the glass functional sheet, and the conducting layers respectively correspond to electrode layers in the X-axis direction and the Y-axis direction. When a finger touches the touch screen, a coupling capacitor is formed on the surface of the touch screen due to the human body electric field, and the controller obtains the position of a touch point through calculation, so that the purpose of touching the touch screen is achieved. Based on the convenience of touch operation, the projected capacitive screen is now widely used in various fields such as mobile phones, computers, electrical appliances and the like in our daily life. However, the existing touch screen only adopts a combination mode of a glass cover plate and a glass functional sheet, and the two sides of the glass functional sheet are both provided with ITO conductive layers, so that after the glass functional sheet is attached to the glass cover plate, the ITO conductive layer on the other side of the glass functional sheet is exposed, and the circuit is easily scratched when the touch screen is in use, so that the touch screen loses the touch function, and inconvenience is brought to the use of people.
Disclosure of Invention
The invention provides a scratch-resistant glass-structure projection type capacitive screen, aiming at solving the problem that the existing projection type capacitive touch screen cannot work due to the fact that lines are easy to scratch in use.
The technical scheme adopted by the invention for solving the technical problems is as follows: the glass functional sheet comprises a glass functional sheet and a glass cover plate, wherein ITO conducting layers are arranged on two sides of the glass functional sheet respectively, one side of the glass functional sheet is pasted with the glass cover plate through SCA optical cement, a glass bottom plate is arranged on the other side of the glass functional sheet, and the glass bottom plate is pasted with the glass functional sheet through the SCA optical cement. Because the invention adopts a 3-layer glass structure, namely the structure of the glass cover plate, the glass functional sheet and the glass bottom plate, the glass functional sheet with ITO conductive layers arranged on two sides is effectively protected, and because the scratch resistance of the glass cover plate and the glass bottom plate is far higher than that of the ITO conductive layers of the functional sheet glass, and the ITO conductive layers can not be damaged by external force, the scratch can be effectively prevented.
The invention has the beneficial effects that: when the operation of people is not influenced, the product is more resistant to scratch, the function is more guaranteed, the working stability of the touch screen is improved, and the service life of the product is effectively prolonged. The product has simple structure and is beneficial to popularization.

Detailed Description
As shown in fig. 1, in the structure of the conventional capacitive touch screen, a double-layer glass combination mode of a glass cover plate and a glass functional sheet is widely adopted, wherein ITO conductive layers (3) and (4) are arranged on two sides of the glass functional sheet (1), and SCA optical cement (5) is used for adhering the glass cover plate and the glass functional sheet, so that the glass cover plate and the glass functional sheet are combined into a whole. However, because the ITO conductive layers are arranged on the two surfaces of the glass functional sheet, the ITO conductive layer (4) on one surface of the glass functional sheet is still exposed after combination, and is easy to scratch when in use, thereby influencing the use of products.
As shown in figure 2, the invention adopts a three-layer glass structure, wherein ITO conductive layers (3) and (4) are arranged on two surfaces of a glass functional sheet (1), one surface of the glass functional sheet is attached to a glass cover plate (2) through SCA optical cement (5), and the other surface of the glass functional sheet is attached to a glass bottom plate (6) through SCA optical cement (7), so that the glass functional sheet with the ITO conductive layers on the two surfaces can be effectively protected, the scratch in use is prevented, the normal use of the product is ensured, the working stability of the touch screen is improved, and the product performance is improved.
