A kind of electric resistance touch screen of seamless applying
Technical field
The utility model belongs to the touch control device technical field, relates in particular to a kind of electric resistance touch screen of seamless applying.
Background technology
At present, electric resistance touch screen is made up of the ITO film of reaching the standard grade, the ito glass that rolls off the production line, the strong point and double faced adhesive tape, after the ITO film of reaching the standard grade makes up with the ito glass that rolls off the production line, for preventing Newton's ring, can keep certain clearance between the two, the depression sense will appear in touch-screen in the touch process like this, and flatness is good inadequately, influences appearance effect.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of electric resistance touch screen of seamless applying is provided, and its can reduce to reach the standard grade the ITO film and the gap between the ito glass of rolling off the production line are improved the flatness of touch-screen and don't Newton's ring occurred.
The utility model is to realize like this, a kind of electric resistance touch screen of seamless applying, comprise the ito glass that rolls off the production line, the described ito glass that rolls off the production line is provided with the silver slurry inside casing that rolls off the production line, also be provided with some strong points that are positioned at the described silver slurry inside casing that rolls off the production line on the described ito glass that rolls off the production line, the silver slurry inside casing applying of reaching the standard grade of the described silver slurry inside casing and that rolls off the production line, the described silver slurry inside casing of reaching the standard grade is provided with the ITO film of reaching the standard grade, the described ITO of the reaching the standard grade film adopts the PET material to make, the described ITO of reaching the standard grade film upper surface is provided with a PET pad, and described PET pad is aimed at the zone of the described silver slurry inside casing of reaching the standard grade.
Particularly, the described silver slurry inside casing that rolls off the production line is fitted by a two-sided adhesive tape and the described silver slurry inside casing of reaching the standard grade.
Because the utility model is discharged the electric resistance touch screen gas inside by increasing the PET pad, thereby both can accomplish seamless applying, can prevent Newton's ring again, greatly improved the flatness of electric resistance touch screen, improved appearance effect, reduced operating pressure simultaneously, the touch reaction speed of raising.
Description of drawings
In order to be illustrated more clearly in the technical solution of the utility model, to do to introduce simply to the accompanying drawing of required use among the embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the schematic diagram of the electric resistance touch screen of a kind of seamless applying of providing of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
As shown in Figure 1, the electric resistance touch screen of a kind of seamless applying that the utility model embodiment provides, comprise the ito glass 1 that rolls off the production line, the ito glass 1 that rolls off the production line is provided with the silver slurry inside casing 2 that rolls off the production line, roll off the production line and also be printed with some strong points 3 that are positioned at the silver slurry inside casing 2 that rolls off the production line on the ito glass 1, roll off the production line silver slurry inside casing 2 by a two-sided adhesive tape 4 and silver slurry inside casing 5 applyings of reaching the standard grade, the silver slurry inside casing 5 of reaching the standard grade is provided with the ITO film 6 of reaching the standard grade, the ITO film 6 of reaching the standard grade adopts the PET material to make, the ITO film 6 upper surfaces of reaching the standard grade are provided with a PET pad 7, and PET pad 7 is aimed at the zone of the silver slurry inside casing 5 of reaching the standard grade.
The assembling process of electric resistance touch screen of the present utility model is: the ito glass 1 that at first will roll off the production line is located on the platform 8 of pressing roasting machine, then at the ito glass 1 printing strong point 3 that rolls off the production line, the silver slurry inside casing 2 that then will roll off the production line is fitted by two-sided tape 4 and the silver slurry inside casing 5 of reaching the standard grade, the ITO film 6 of then will reaching the standard grade again is located on the silver slurry inside casing 5 of reaching the standard grade, afterwards PET pad 7 is located at and is reached the standard grade the ITO film 6 upper surfaces and aim at the zone that the silver of reaching the standard grade is starched inside casing 5, under the pressure effect of the upper cover plate 9 of pressing roasting machine, the electric resistance touch screen gas inside is discharged at last, the ITO film 6 of reaching the standard grade is directly fitted with the ito glass 1 that rolls off the production line, and the ITO film 6 and rolling off the production line of reaching the standard grade is separated by the strong point 3 between the ito glass 1.
Because the utility model is discharged the electric resistance touch screen gas inside by increasing PET pad 7, thereby both can accomplish seamless applying, can prevent Newton's ring again, greatly improved the flatness of electric resistance touch screen, improved appearance effect, reduced operating pressure simultaneously, the touch reaction speed of raising.
The above is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
