From induction electrode unit discharge and recharge time t ≈ RC, the electrode unit R caused due to the increase of contact conductor length in order to equilibrium each row induction electrode unit increases the performance difference caused, the balance that induction electrode unit discharge and recharge time t ≈ RC can be tried one's best by the size changing C, thus obtain more satisfactory even performance.
Please refer to Fig. 1, be arranged on public electrode unit 140 on substrate 130 and induction electrode unit 150 is made up of transparent conductive material, thickness is generally 100 ~ 500 Ethylmercurichlorendimides.According to electricity rule, when two just to electrifying electrodes after, can form an electric field between two electrodes, the side of electrode is also an equivalent little electric field.The side of two electrodes also forms a plane-parallel capacitor, and according to computing formula C=(ε the S)/d of parallel plate capacitor, wherein, ε: dielectric permittivity between pole plate, S: pole plate right opposite amasss, d: polar plate spacing; Want the size changing C, can be realized by adjustment S or d, maybe can by adjusting S and d to realize simultaneously.
Thus, the central scope of the monolayer multipoint capacitive touch screen of the present embodiment is: by changing the size of induction electrode unit, reach the object simultaneously adjusting S and d, and then change the size of C, make the balance that each induction electrode unit discharge and recharge time t ≈ RC tries one's best.
Please refer to Fig. 2, show the schematic diagram of the electrod-array of the monolayer multipoint capacitive touch screen of energy balanced each electrode charge and discharge time.
The visible area of this monolayer multipoint capacitive touch screen is provided with two row electrodes, can certainly be multiple row, and this sentences two and is classified as example and is described.Each row electrode comprises the first electrode 210 of a strip and is multiplely placed in the first electrode 210 side and the second electrode unit 220 be arranged in order, and each second electrode unit 220 is drawn from the bottom of visible area downwards by independently contact conductor 230.On the direction that contact conductor 230 is drawn, on namely downward shown in arrow X in Fig. 2 direction, each second electrode unit 220 size increases gradually.Like this, from top to bottom, the spacing d of each second electrode unit and the first electrode 210 progressively reduces, i.e. d1>d2>d3>d4 in Fig. 2; Meanwhile, the right opposite between each second electrode unit 220 and the first electrode 210 amasss S and progressively increases.According to formula C=(ε S)/d, from top to bottom, S progressively increases, d progressively reduces, and the C therefore between each second electrode unit 220 and the first electrode 210 progressively increases, and from top to bottom, contact conductor length and the resistance value R of each second electrode unit obviously reduce gradually, therefore, according to t ≈ RC, the discharge and recharge time of each second electrode unit is comparatively balanced.
