Abstract
The utility model provides a touch screen protective plate which comprises at least one metal layer and at least one protective plate layer, wherein the protective plate layer is platy, and the metal layer and the protective plate layer are connected into a whole. The touch screen protective plate has the advantages of good protecting effect, long service life, capability of effectively preventing a touch screen from being accidentally touched and the like.
Description
Technical field
The utility model belongs to the touch-screen field, relates to a kind of touch screen protective plate, relates in particular to a kind of capacitive touch screen fender.
Background technology
Touch screen (Touch panel) is called contact panel again, it is the induction type liquid crystal indicator that can receive input signal such as contact, when having contacted the graphic button on the screen, haptic feedback system on the screen can drive various hookup mechanisms according to the formula of programming in advance, can be in order to the push button panel of dessert machine tool formula, and produce lively visual and sound effects by liquid crystal display picture.
Touch-screen system is a kind of integrated device that shows and touch control, uses extensively day by day at present, and industry, service sector, military affairs, circulation industry, municipal administration, family places such as (mobile phones) have all obtained large-scale application.Because touch-screen system is interactive bridge, and is more extensive with people's contact gear ratio.
Touch-screen system is on architecture principle, and touch-screen system is formed by touching detection touch-screen system parts and touch screen controller; Touch detection part and be installed in the indicator screen front, for detection of user touch location, send touch screen controller after the acceptance; And the main effect of touch screen controller is to receive touch information from touch point detection device, and converts it to contact coordinate, gives CPU again, and its can receive simultaneously the order that CPU sends and be carried out.Say from classification, can be divided into five basic kind: vector pressure sensing technology touch-screen system, resistive technologies touch-screen system, capacitance technology touch-screen system, infrared technology touch-screen system, surface acoustic wave technique touch-screen system.
Wherein, capacitive touch screen is four layers of compound glass screen, and the inside surface of glass screen and interlayer respectively are coated with one deck ITO; outermost layer is the silicon soil glassivation that has only 0.0015mm thick; interlayer ITO coating is made workplace, and four electrodes are drawn at four angles, and internal layer ITO is for shielding layer to guarantee working environment.When the user touches capacitance plate, because people's bulk electric field, user's finger and workplace form a coupling capacitance, because be connected to high-frequency signal on the workplace, so finger is walked a very little electric current, this electric current flows out the electrode from four angles of screen respectively, and the electric current of four electrodes of flowing through in theory and finger are proportional to four jiaos distance, and controller calculates the position by the precision to four current ratios.
In the touch-screen product of prior art, touch the screen of touch-screen and cause accident to open or move some program for fear of accident, perhaps in order effectively to protect touch-screen to avoid damaging.The touch-screen product of prior art need add a touch screen protective plate usually.
But, in the capacitive touch screen fender product of prior art, because can not effectively cutting off the accident of touch-screen, touches by this fender, and cause its protection effect limited.
The utility model content
Can not effectively cut off the accident of touch-screen in view of fender of the prior art is existing and touch, the deficiency of aspect such as its protection effect is limited.The purpose of this utility model is to provide a kind of accident that can effectively cut off touch-screen to touch, and protects touch screen protective plate effective, long service life.
For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of touch screen protective plate, and described touch screen protective plate comprises: at least one metal level; At least one backplate layer, described backplate layer is plates; Described metal level and described backplate layer connect as one.
According to above-mentioned design of the present utility model, described metal level is the metal stratum reticulare.
According to above-mentioned design of the present utility model, described backplate layer and described wire netting is stacked close after, be pressed into one, described metal stratum reticulare embeds described backplate layer.
According to above-mentioned design of the present utility model, described backplate layer is nonmetallic materials backplate layer.
According to above-mentioned design of the present utility model, described backplate layer is coated on the described metal stratum reticulare, and corresponding to described metal stratum reticulare, is a reticulate body.
According to above-mentioned design of the present utility model, described backplate layer is one deck at least.
According to above-mentioned design of the present utility model, described backplate layer is multilayer, and described metal stratum reticulare is arranged between the described multilayer backplate layer.
According to above-mentioned design of the present utility model, described backplate layer and described metal stratum reticulare are multilayer, and described metal stratum reticulare and described backplate are folded layer by layer the back pressing is set is one.
Advantage of the present utility model and beneficial effect are: have the accident that can effectively cut off touch-screen and touch, protect advantages such as effective, long service life.
