Detailed description of the invention
The thin film switch with window electrostatic-proof function of the present invention as shown in Figure 1, with prior art phaseWith, primer layer 1, lower line layer 2, line key layer 3, electrostatic layer that it is pasted from the bottom up successively9, face key layer 4, panel layer 5. Primer layer 1, line key layer 3, face key layer 4 are tacky on two sides, the endGlue-line 1 bottom surface Pasting is on the pcb board of product, and lower line layer 2 is provided with switch key sheet 6,On line key layer 3, face key layer 4, have the hole corresponding with switch key sheet 6, on panel layer 5Be provided with transparent window 7, face key layer 4 below transparent window 7, electrostatic layer 9, line key layer 3, underOn line layer 2, primer layer 1, have corresponding hole. Unlike the prior art, face key layer 4Hole in be provided with a transparent conductive sheets 8, thin film switch ground connection are drawn in electrostatic layer 9 one end, and thoroughlyBright conducting strip 8 is pasted mutually with the transparent window 7 of top, the edge of transparent conductive sheets 8 and staticLayer 9 edge, hole conducts electricity stickup mutually.
Transparent conductive sheets 8 upper surfaces are provided with OCA optical cement 10, and by OCA optical cement 10 and saturatingBright window 7 is mutually bonding.
The edge, hole of electrostatic layer 9 is provided with conducting resinl 11, and by conducting resinl 11 and transparent conductive sheets 8Mutually bonding.
In the present embodiment, transparent conductive sheets 8 adopts and has high transmission rate, definition and conductive characteristicITO electro-conductive glass sheet, certainly also can adopt the material of other similar performance.
The concrete earthing mode of electrostatic layer 9 can adopt a ground hole 12 is set on exit, passes throughGround hole 12 is connected with earth connection or metal chassis on pcb board.
Electrostatic layer 9 adopts aluminium foil, also can adopt similarly other conductive material, or as aluminium wire nettingCopper mesh.
In sum, the thin film switch with window electrostatic-proof function of the present invention, by lower circuitTop paste the static net of one deck ground connection, a transparent conductive sheets 8 is set in the hole of face key layer 4,And conducting resinl 11 is crossed to by static Netcom fit with transparent conductive sheets 8, thereby play the anti-quiet of window placeElectricity effect, the while has also ensured the transparency of window. Through evidence, adopt the window that has of the present inventionThe thin film switch of mouthful electrostatic-proof function, can significantly improve the antistatic grade of product transparent window 7,Make product can effectively be applied in the occasion that various static is higher, and simple in structure, easy to make, energyEnough, for enterprise can bring significant economic benefit, prospect is very wide.
But those of ordinary skill in the art will be appreciated that, above embodiment is onlyBe used for illustrating the present invention, and be not used as limitation of the invention, as long as in essence essence of the present inventionIn god's scope, variation, modification to the above embodiment all will drop on claims of the present inventionIn scope.
