Abstract
The utility model discloses a novel capacitance type touch screen which comprises a PET (Polyethylene Terephthalate) layer, a substrate and an optic film, wherein the PET layer is provided with patterns and characters; the substrate and the optic film are arranged on the PET layer; pins are arranged at two ends of the substrate; an ITO (Indium Tin Oxide) film is arranged on the back of the optic film; an OCA (Optically Clear Adhesive) film is arranged on the ITO film; toughened glass is arranged outside the OCA film; and double-faced adhesive tape is arranged between the optic film and the ITO film. The OCA film and the toughened glass are arranged on the ITO film in sequence so that the wear resistance of the touch screen is greatly improved; and the double-faced adhesive tape is arranged between the optic film and the ITO film to lead the optic film, the ITO film and the OCA film to form a real whole, so that the service life of the touch screen is prolonged.
Description
Technical field
The utility model relates to the input media of man-machine interaction, particularly a kind of novel capacitance-type touch-screen.
Background technology
Touch-screen (Touch Panel) is called touch screen, contact panel again, it is widely used on the various electronic products as a kind of input media of man-machine interaction, the user can be by the variation of pointing or the special pens touch screen produces electric signal, discern and selection operation being arranged in the shown literal of touch-screen back display device, symbol, menu etc., thereby realization is to the input operation of equipment.
Common on the market touch-screen mainly is divided into resistance-type and condenser type.Wherein the principle of work of capacitive touch screen is to utilize the induction by current of human body to carry out work, it is based on tellite, and the multilayer ITO film that apts outside substrate is because it is not a real integral body, used wearing and tearing easily for a long time, so serviceable life is shorter.
The utility model content
The purpose of this utility model is to provide a kind of capacitive touch screen of not easy to wear, long service life.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of novel capacitance-type touch-screen, comprise the pet layer that is provided with pattern and literal and be located at substrate and optical film on the pet layer, described substrate two ends are provided with pin, the described optical film back side is provided with the ITO film, described ITO film is provided with the OCA film, and the OCA film is provided with tempered glass outward.
In addition, be provided with double faced adhesive tape between described optical film and the ITO film.
The beneficial effects of the utility model are: be provided with OCA film and tempered glass on the ITO film successively, can improve the fastness to rubbing of touch-screen greatly, prolong the serviceable life of touch-screen.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1, shown in Figure 2, the utility model discloses a kind of novel capacitance-type touch-screen, comprise the pet layer 1 that is provided with pattern and literal and be located at substrate 2 and optical film 3 on the pet layer 1, described substrate 2 two ends are provided with pin 5, described optical film 3 back sides are provided with ITO film 4, described ITO film 4 is provided with OCA film 6, is provided with tempered glass 7 outside the OCA film 6, is provided with double faced adhesive tape between described optical film 3 and the ITO film 4; Owing to be provided with double faced adhesive tape between optical film 3 and the ITO film 4, make optical film 3, ITO film 4 and OCA film 6 become a real integral body, and be provided with OCA film 6 and tempered glass 7 on the ITO film 4 successively, and can improve the fastness to rubbing of touch-screen greatly, prolong the serviceable life of touch-screen.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these subordinates are in protection domain of the present utility model.
