Abstract
The utility model provides an electrode routing structure of a capacitive screen, which comprises sensing electrodes which form the rows and the lines of sensors, wherein each sensing electrode is in a rhombus shape; the sensing electrodes are not communicated mutually and lead out electrode leads; each electrode lead is located on a conductive film of a same layer; electrode leads are located between gaps which are arranged between each sensing electrode and are not contacted mutually. According to the utility model, an intersection point cannot be located between an X electrode and a Y electrode which are vertical mutually; simultaneously, a bridging design is processed unnecessarily; therefore, the electrode routing structure prevents generating fracture because of relatively large difference between an insulating layer film and an ITO or a metal film thickness; production technology is simplified; finished product ratio is increased; because routing is arranged on the conductive film of the same layer, the thickness of a touch screen can be reduced, light transmittance is increased, and energy consumption is reduced.
Description
Technical field
The invention belongs to the display screen field, be specifically related to a kind of electrode structure of capacitance plate.
Background technology
Existing touch-screen mainly is divided into two kinds, resistive touch screen and capacitive touch screen, because factors such as transmittance, sensitivity, serviceable lifes, resistive touch screen is eliminated basically, and capacitive touch screen is occupied an leading position.But capacitance plate also has some unfavorable places to overcome, and capacitance touch screen is made up of polylith glass or resin film generally speaking, and thickness is bigger, and the applying yield rate is not high in the production run; Owing between X electrode and the Y electrode point of crossing is arranged, cause short circuit in addition, need do the design (like figure below) of putting up a bridge for avoiding the point of crossing; This makes complex manufacturing; Accuracy requirement is high, reduces the rate that manufactures a finished product, simultaneously; The bridging mode can be bigger because of the difference of insulating layer of thin-film and ITO or thickness of metal film, is easy to generate breakage problem.
The utility model content
The technical matters that the utility model will solve provides a kind of novel electrode Wiring structure, and it can make and no longer include the point of crossing between X electrode and the Y electrode and need not do the design of putting up a bridge.
A kind of electrode Wiring structure of realizing the capacitance plate of such scheme of the present invention comprises the induction electrode of the row and column that forms sensor, and each induction electrode assumes diamond in shape.Be not communicated with mutually between each induction electrode and extraction electrode lead-in wire separately, each contact conductor is in on one deck conductive film, and described contact conductor is between the gap between each induction electrode and do not contact mutually.
Further; Described contact conductor all is positioned on the positive conductive film of induction electrode, and in addition, the back side of induction electrode also comprises a back side conductive film; Described back side conductive film can play shielding action, prevents electrostatic interference and the electromagnetic exposure that stops internal electronic element.
The invention has the beneficial effects as follows: can make and also need not do the design of putting up a bridge when no longer including the point of crossing between orthogonal X electrode and the Y electrode; Prevent to produce greatly the problem of fracture because of the difference of insulating layer of thin-film and ITO or thickness of metal film; Simplify production technology, improve yield rate; And, can reduce the thickness of touch-screen because its cabling all places on one deck conducting film, improve transmittance, cut down the consumption of energy; The back side is provided with conductive material, can play the effect of shielding, prevents electrostatic interference and the electromagnetic exposure that stops internal electronic element.

Embodiment
The electrode Wiring structure of this novel described a kind of capacitance plate comprises the induction electrode of the row and column that forms sensor, and each induction electrode assumes diamond in shape.Be not communicated with mutually between each induction electrode and extraction electrode lead-in wire separately, each contact conductor is in on one deck conductive film, and described contact conductor is between the gap between each induction electrode and do not contact mutually.
Further describe; Described contact conductor all is positioned on the positive conductive film of induction electrode, and in addition, the back side of induction electrode also comprises a back side conductive film; Described back side conductive film can play shielding action, prevents electrostatic interference and the electromagnetic exposure that stops internal electronic element.
The above is not that technical scope of the present invention is done any restriction, all according to this new technique essence to above any modification, equivalent variations and modification that embodiment did, all still belong in the scope of this new technique scheme.
