In the first embodiment shown in Fig. 2, the structure of each electrode unit 40 is identical.The first electrode group 41 of each electrode unit 40 has 11 the first electrodes 43, the second electrode groups 42 and has 11 the second electrodes 44.
Wherein, in the first electrode group 41, the first electrode 43 that partial continuous is arranged is the first kind the first electrode a1, and the first electrode 43 that partial continuous is arranged is Equations of The Second Kind the first electrode a2, and the continuously arranged first kind the first electrode a1 and continuously arranged Equations of The Second Kind the first electrode a2 alternately occur.In the embodiment shown in Fig. 2, three continuously arranged the first electrodes 43 that are positioned at center section are the first kind the first electrode a1, and three first kind the first electrode a1 both sides are respectively four continuously arranged Equations of The Second Kind the first electrode a2; In four Equations of The Second Kinds, the first electrode a2 of both sides, spaced two the first electrodes are electrically connected, and that is to say that the electrode between interconnective two Equations of The Second Kinds the first electrode a2 is: an Equations of The Second Kind first electrode a2.
In the second electrode group 42, the second electrode 44 that partial continuous is arranged is the first kind the second electrode b1, the second electrode 44 that partial continuous is arranged is Equations of The Second Kind the second electrode b2, and the continuously arranged first kind the second electrode b1 and continuously arranged Equations of The Second Kind the second electrode b2 alternately occur.In the embodiment shown in Fig. 2, three continuously arranged the second electrodes 44 that are positioned at two continuously arranged the second electrodes 44 of lateral edges A mono-side, relative opposite side edge B mono-side are the first kind the second electrode b1, and remaining six continuously arranged the second electrodes 44 are Equations of The Second Kind the second electrode b2; In six Equations of The Second Kind the second electrode b2, wherein three spaces are arranged and are linked together, and another three spaces are arranged and linked together, and that is to say that the electrode between interconnective two Equations of The Second Kinds the second electrode b2 is: an Equations of The Second Kind second electrode b2.
In this first embodiment, in all electrode units, the first electrode that partial continuous is arranged is the first kind the first electrode a1, and the first electrode 43 that partial continuous is arranged is Equations of The Second Kind the first electrode a2, and the continuously arranged first kind the first electrode and continuously arranged Equations of The Second Kind the first electrode alternately occur; The second electrode 44 that partial continuous is arranged is the first kind the second electrode b1, and the second electrode 44 that partial continuous is arranged is Equations of The Second Kind the second electrode b2, and the continuously arranged first kind the second electrode and continuously arranged Equations of The Second Kind the second electrode alternately occur.In the utility model, being not limited to this situation, can be this situation at least one electrode unit.
Pay particular attention to, important document that must be satisfied in touch-screen is: each first electrode need have uniqueness with the coupling capacitance node that the second corresponding electrode forms.Therefore the coupling capacitance node that, each second electrode in each first electrode and second electrode group of the first electrode group forms all needs to have uniqueness.
In each electrode unit 40, the first kind the first electrode a1 is owing to being the first electrode independently, and it has uniqueness with the coupling capacitance node that the second corresponding electrode 44 forms.Not corresponding same the second electrode 44 of Equations of The Second Kind the first electrode a2 interconnecting, and, Equations of The Second Kind the first electrode a2 interconnecting only have one relative with in Equations of The Second Kind the second electrode b2 interconnecting one, form coupling capacitance node, therefore Equations of The Second Kind the first electrode a2, interconnecting also has uniqueness with the coupling capacitance node that the second corresponding electrode 44 forms.Not corresponding same the first electrode 43 of Equations of The Second Kind the second electrode b2 interconnecting, and, Equations of The Second Kind the second electrode b2 interconnecting only have one relative with in Equations of The Second Kind the first electrode a2 interconnecting one, form coupling capacitance node, therefore Equations of The Second Kind the second electrode b2, interconnecting also has uniqueness with the coupling capacitance node that the first corresponding electrode 43 forms.

The individual layer multiple spot capacitance touch screen of the first embodiment can reduce the number of the extension line of drawing from each electrode unit with respect to the individual layer multiple spot capacitance touch screen of prior art, and then, can solve the problem of the adjacent extension line short circuit that each electrode unit occurs in routing technique, improve touch-screen and produce yield.
Such as: in the first embodiment shown in Fig. 2, the first electrode number in each electrode unit 40 is 11, and the second electrode number is 11, and the coupling capacitance interstitial content that can provide is accordingly 21.The individual layer multiple spot capacitance touch screen of prior art, if the coupling capacitance interstitial content that need to provide is 21, the first electrode number needing is 21, second electrode, corresponding extension line number is 22.And, in this first embodiment, because interconnective Equations of The Second Kind the first electrode a2 shares an extension line, interconnective Equations of The Second Kind the second electrode b2 shares an extension line, therefore can reduce the extension line number of drawing with respect to the individual layer multiple spot capacitance touch screen of prior art from each electrode unit 40, reduce the short circuit problem too closely causing due to distance between adjacent extension line, improve touch-screen and produce yield.
And, in this embodiment, in the first electrode group, have and in the first kind the first electrode and Equations of The Second Kind the first electrode, the second electrode group, there is the first kind the second electrode and Equations of The Second Kind the second electrode, therefore, the both sides of what the extension line of drawing from each electrode unit can disperse be distributed in electrode unit, substantially be distributed in electrode unit one side with respect to extension line and can increase the distance between adjacent extension line, better avoid the short circuit problem too closely causing due to distance between adjacent extension line, improve touch-screen and produce yield.
In addition, the both sides that are distributed in electrode unit that can disperse due to the extension line of drawing from each electrode unit, therefore, in whole touch-screen, all there will not be between adjacent electrode unit and there is the region that there is no extension line, the problem that need to cause at this region division suspension piece the performance such as the linearity and degree of accuracy of touch-screen to reduce; Meanwhile, can avoid along touch-screen one side carry out cabling, opposite side does not have cabling, and causes figure left-right asymmetry, edge performance to have the problem of larger impact.
In the first embodiment, the extension line number of drawing from the first electrode group 41 is: 7.The extension line number of drawing from the second electrode group 42 is: 7.That is to say, in the first embodiment, in each electrode unit, the quantity of the quantity of the extension line being connected with the first electrode, the extension line that is connected with the second electrode equates.In touch-screen, the figure of the figure of electrode, extension line is all symmetric like this, between adjacent two electrode units, substantially there will not be the region that there is no cabling, thereby can make on touch-screen figure better symmetrical, promotes the edge performance of touch-screen.
In this first embodiment, in adjacent two electrode units 40, the first electrode 43 of one of them electrode unit 40 is positioned at a side of the second electrode 44, and the first electrode 43 of another electrode unit 40 is positioned at the opposite side of the second electrode 44.Such as, in Fig. 2, in leftmost two electrode units 40, the first electrode 43 of left side electrode unit 40 is positioned at the left side of the second electrode 44, and the first electrode 43 of the right electrode unit 40 is positioned at the right side of the second electrode 44.Therefore, the first electrode of whole touch-screen and the second electrode are mirror image symmetric offset spread.
In the first embodiment, the structure of each electrode unit is identical, and first electrode and the second electrode be mirror image symmetric offset spread, therefore, being positioned at extension line draws the end of opposite direction direction, the first adjacent and relative electrode 43, the second adjacent and relative electrode 44 and can share an extension line.In the embodiment shown in Fig. 2, extension line is along drawing touch-screen from a lateral edges A to the direction of relative opposite side edge B, corresponding, is positioned at the first electrode 43 that a lateral edges A is adjacent and relative, the adjacent and relative shared extension line of the second electrode 44.Like this, not only can reduce extension line quantity, and, also facilitate the cabling of extension line.Such as: in Fig. 2, in leftmost two electrode units 40, be positioned at the second electrode 44 that a lateral edges A is adjacent and relative and share an extension line; In two middle electrode units 40, be positioned at the first electrode 43 that a lateral edges A is adjacent and relative and share an extension line.
In the first embodiment, because Equations of The Second Kind the first electrode a2, Equations of The Second Kind the second electrode b2 need to utilize connecting line to couple together, these connecting lines can form " redundancy " electric capacity, therefore, in each electrode unit 40, between the first electrode group and the second electrode group, be provided with the extension line Sref with preset reference voltage drawing along column direction, to eliminate " redundancy " electric capacity being formed by connecting line.In addition, owing to also can producing electric capacity between these connecting lines and each lead-in wire, and distance between each connecting line and each lead-in wire is not etc., therefore the electric capacity that each connecting line and each lead-in wire produce is also unequal, this can cause the electric capacity of each touch point inhomogeneous, can between the first electrode group and the second electrode group, arrange that to have preset reference voltage extension line Sref(not shown), can balance not wait by above-mentioned distance the electric capacity inequality producing.Wherein, described extension line Sref can ground connection, and corresponding preset reference voltage is zero; The preset reference voltage of described extension line Sref can be also a certain level signal.
In the utility model, be not limited to, between the first electrode group 41 of each electrode unit 40 and the second electrode group 42, the extension line Sref with preset reference voltage drawing along column direction is set, can be for the extension line Sref with preset reference voltage drawing along column direction being set between the first electrode group at least one electrode unit and the second electrode group.
