A high-performance anti-electromagnetic radiation projection type capacitive touch screen comprises a glass cover plate, a glass function sheet and a glass blocking sheet, wherein ITO conducting layers are respectively arranged on two sides of the glass function sheet, an ITO conducting layer is arranged on one side of the glass blocking sheet, a grounding flat cable is arranged on the ITO conducting layer, and SCA optical adhesive layers are adhered among the glass cover plate, the glass function sheet and the glass blocking sheet. The utility model discloses the ITO conducting layer on the well glass separation blade can be gathered the electric current of sensing to derive through the ground connection winding displacement, can effectively solve the electromagnetic interference of machine display screen and inside production, be a high performance anti-electromagnetic radiation's projection formula electric capacity touch-sensitive screen, make the touch-sensitive screen have good performance, avoid it to produce unstable phenomenon because of electromagnetic radiation.
Description
Technical Field
The utility model relates to a touch-sensitive screen, specifically speaking are high performance anti-electromagnetic radiation's projection formula electric capacity touch-sensitive screen.
Background
The projection type capacitive touch screen widely used at present is composed of a lower glass function sheet and a glass cover plate, wherein ITO conductive layers are respectively coated on two surfaces of the glass function sheet, and the glass function sheet is adhered to the glass cover plate through SCA optical cement. The ITO conductive layer has a strong conductive property, so that the ITO conductive layer is easily interfered by electromagnetic radiation related to current in an external environment, once current exists near the ITO conductive layer, a cursor of the touch screen can be shifted, which is not beneficial to operation, i.e. people generally know that the touch screen has poor stability, and particularly, the touch screen has more obvious reaction when being used in high-end application fields such as industrial control, so that inconvenience is brought to people.
Disclosure of Invention
In order to solve the not enough problem that current projection type capacitive touch screen exists, this reality is novel to provide a high performance electromagnetic radiation resistant's projection type capacitive touch screen, and this touch screen not only makes things convenient for people to operate and use, is difficult for receiving external environment's interference moreover, and the stability of its work is high.
The utility model provides a technical scheme that its technical problem adopted is: the glass function piece comprises a glass cover plate and a glass function piece, wherein ITO conducting layers are respectively arranged on two sides of the glass function piece, an SCA optical adhesive layer is arranged between the glass function piece and the glass cover plate, a glass blocking piece is arranged on the other side of the glass function piece, the ITO conducting layers are arranged on the glass blocking piece and connected with a grounding flat cable, and the SCA optical adhesive layer is arranged between the glass blocking piece and the glass function piece. The utility model discloses the ITO conducting layer on well glass separation blade is used for gathering induced-current to utilize the ground connection winding displacement to derive the electric current that senses on with the ITO conducting layer, just so can effectively solve the electromagnetic interference of machine display screen and inside production, thereby avoid producing unstable phenomenon.
The utility model has the advantages that: the touch screen has good anti-interference performance while the operation of people is not influenced, the working stability of the touch screen is improved, the product structure is simple, the cost is relatively low, and the touch screen is beneficial to popularization.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic sectional structure diagram of the present invention.
Code description in the figure: 1-glass functional sheet; 2-a glass cover plate; 3. a 4, 7-ITO conductive layer; 5. 8-SCA optical cement; 6-glass baffle plate; 9-ground cable.
Detailed Description
As shown in fig. 1, ITO conductive layers are respectively arranged on two sides of a glass functional sheet (1), one side of the glass functional sheet is adhered to a glass cover plate (2) through SCA optical cement, a glass blocking sheet (6) is arranged on the other side of the glass functional sheet, the ITO conductive layers are arranged on the glass blocking sheet, the ITO conductive layers are connected with a grounding flat cable (9), and the glass functional sheet (1) and the glass blocking sheet (6) are adhered through the SCA optical cement. The utility model discloses structurally formed three-layer ITO conducting layer, wherein ITO conducting layer (3), (4) on the glass function piece are used for data acquisition, and ITO conducting layer (7) on the glass separation blade then are used for the collection of induced-current, be equipped with the ground connection winding displacement on this ITO conducting layer simultaneously, can derive the electric current that senses through the ground connection winding displacement, make whole touch-sensitive screen avoid external environment electric current's influence, good interference killing feature has, the stability of touch-sensitive screen work has been improved, the product structure is simple, the cost is relatively low, do benefit to the popularization.
