Abstract
The utility model provides an anti-static touch screen, which comprises an upper substrate and a lower substrate. The upper substrate comprises a touch conducting layer, a first protective sheet and a static conducting layer from bottom to top sequentially. The touch conducting layer is provided with electrodes, and a static pin is arranged on one side of the static conducting layer and electrically connected with an earth wire of an electronic equipment main board by the aid of a lead. The anti-static touch screen can effectively remove static charges on the surface of the screen and prevent static charge accumulation so that touch accuracy of the touch screen is ensured.
Description
Technical field
The utility model relates to photoelectric field, especially a kind of touch-screen with antistatic characteristic.
Background technology
Along with developing rapidly of electronic technology, big part has touch controllable function in the present LCD, as mobile phone, panel computer etc., because touch technology is convenient to operation, and can make the electronic equipment volume significantly reduce (saving physical keyboard), therefore favored by users.
For touch controllable function, mainly be the touch-screen body by covering the liquid crystal display surface and realize with the controller that this touch-screen body is electrically connected.Present touch-screen body mainly comprises resistance screen, capacitance plate, piezoelectricity screen, infrared ray screen, surface acoustic wave screen, plant touch-screen for first three, all realize touch controllable function by electrical effect, therefore comparatively sensitive for the electrical effect reaction of screen surface, in case static charge appears in the screen surface, and can not in time lead and remove, then will influence the touch-screen operate as normal.And in fact, touch-screen generally is installed on the portable set, and modal is mobile phone; its screen body usually can rub with clothes, thereby makes the screen body surface wear static charge, does not remove if it is not in time led; then be easy to cause the touch-control deviation, the touch point can not accurately be caught.
Here, the simple earlier structure of common electrical effect touch-screen down of introducing, it mainly comprises upper substrate and infrabasal plate, described upper and lower base plate is oppositely arranged, described upper substrate comprises top one deck heat insulating lamella and following layer of transparent conductive layer, described infrabasal plate is the electro-conductive glass that conducting surface makes progress, perhaps comprise following one deck insulation spacer and top layer of transparent conductive layer, also be provided with electrode on the described transparency conducting layer, be electrically connected with the controller on the electronic equipment mainboard, be used for the conduct electricity effect.
For present touch-screen, the problem of screen surface accumulation static charge is not handled, therefore be necessary to make improvements.
Summary of the invention
For above-mentioned problem, the purpose of this utility model is to provide a kind of electrostatic prevention touch-screen, and this touch-screen can be led the static charge of removing the screen surface effectively, prevents the accumulation of static charge, thereby has guaranteed the touch-control accuracy of touch-screen.
The technical scheme that its technical matters that solves the utility model adopts is: this electrostatic prevention touch-screen comprises upper substrate, infrabasal plate; described upper substrate comprises touch-control conductive layer, the first protection thin slice, static conductive layer from top to bottom successively; described touch-control conductive layer is provided with electrode; described static conductive layer one side is provided with the static pin, and the ground wire by lead and electronic equipment mainboard is electrically connected.
As preferably, also be provided with one deck second protection thin slice above the described static conductive layer, so that described static conductive layer is difficult for excessive scratch.
As preferably, the thickness of the described second protection thin slice is thinner than the described first protection thin slice.
As preferably, the periphery of described static conductive layer electrically contacts at the periphery place to prevent them in the inboard of described touch-control conductive layer periphery.
As preferably, described static pin is a bar shaped flat copper sheet, is printed on described static conductive layer one side.
The beneficial effects of the utility model are: this electrostatic prevention touch-screen in use; if static charge appears in the screen surface; then will down move; when arriving the static conductive layer; to be transferred on the ground wire of electronic equipment by the static pin; and lead and remove; owing to be provided with the first protection thin slice of insulation between static conductive layer and the touch-control conductive layer; therefore two conductive layers are unaffected mutually; this touch-screen can be led the static charge of removing the screen surface effectively; prevent the accumulation of static charge, thereby guaranteed the touch-control accuracy of touch-screen.
Description of drawings
Fig. 1 is the sectional view of this electrostatic prevention touch-screen.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
This electrostatic prevention touch-screen comprises upper substrate, infrabasal plate; in the embodiment shown in fig. 1; described upper substrate comprises touch-control conductive layer 4, the first protection thin slice 3, static conductive layer 2 from top to bottom successively; described touch-control conductive layer 4 is made of tin indium oxide; which is provided with electrode (known technology, not shown), described static conductive layer 2 also is made of tin indium oxide; the one side is provided with static pin (not shown), and the ground wire by lead and electronic equipment mainboard is electrically connected.
Above-mentioned electrostatic prevention touch-screen; described static conductive layer 2 tops also are provided with one deck second protection thin slice 1; so that described static conductive layer 2 is difficult for excessive scratch; in fact; described static conductive layer 2 surfaces only need conducting everywhere to get final product; surperficial scratch does not to some extent also influence the transfer of static charge, yet scratch exceedingly will make its life-span shorten.
Above-mentioned electrostatic prevention touch-screen, the thickness of the described second protection thin slice 1 are thinner than the described first protection thin slice 3.
Above-mentioned electrostatic prevention touch-screen, the periphery of described static conductive layer 2 electrically contact at the periphery place to prevent them in the inboard of described touch-control conductive layer 4 peripheries.
Above-mentioned electrostatic prevention touch-screen, described static pin are a bar shaped flat copper sheet, are printed on described static conductive layer 2 one sides.
Above-mentioned electrostatic prevention touch-screen in use; if static charge appears in the screen surface; then will down move, when arriving static conductive layer 2, will be transferred on the ground wire of electronic equipment by the static pin; and lead and remove; because be provided with the first protection thin slice 3 of insulation between static conductive layer 2 and the touch-control conductive layer 4, therefore two conductive layers are unaffected mutually, this touch-screen can be led the static charge of removing the screen surface effectively; prevent the accumulation of static charge, thereby guaranteed the touch-control accuracy of touch-screen.
