[0037] 基板100,基板100划分为感应通道单元布设区110和位于感应通道单元布设区110至少一侧的绑定区120。 [0037] The substrate 100, the substrate 100 is divided into the channel sensing unit 110 and the routing area is located in the channel sensing means 110 at least a binding region layout area 120 side. 所述感应通道单元布设区110布设有多个并列排布的感应通道单元101、多条第一引接线102、和多条第二引接线103。 The layout sensing unit channel region 110 laid in parallel with a plurality of sensing cells 101 arranged in channels, a first plurality of lead wires 102, and a plurality of second lead wires 103. 所述多条第一引接线102与所述多条第二引接线103连接到绑定区120。 The plurality of first lead wires 102 and the plurality of lead wires 103 are connected to the second binding region 120.

[0038] 每一感应通道单元101包括多个第一电极10和多个第二电极11,多个第一电极10用于与多个第二电极11相耦合以形成多个互电容感应节点。 [0038] Each channel unit 101 includes a plurality of sensing electrodes 10 of the first and the second electrodes 11, a plurality of first electrodes 10 coupled to the plurality of the second electrodes 11 to form a plurality of mutual capacitance sensing nodes. 其中,对于每列感应通道单元101,优选地,多个第一电极10呈列排布,多个第二电极11也呈列排布。 Wherein the channel sensing means for each column 101, preferably, the plurality of first electrodes 10 arranged presented, presentation of the plurality of second electrodes 11 are also arranged.

[0041] 需要说明的是,上述第一电极10为驱动电极且第二电极11为接收电极,或第一电极10为接收电极且第二电极11为驱动电极。 [0041] Incidentally, the first electrode 10 of the driving electrode and the second electrode 11 to the receiving electrode, the first electrode 10 or the electrode and the second electrode to receive a drive electrode 11. 且上述第一电极10中的第一类电极1a的面积小于第二类电极1b的面积,每个第二电极11的面积大小相同,均大于第一类电极1a的面积且为第二类电极的面积的正整数倍。 The first electrode 1a and the area of ​​the first electrode 10 is smaller than the area of ​​the electrode 1b of the second type, the area of ​​each second electrode 11 of the same size, greater than the area of ​​a first type and a second electrode 1a based electrode positive integer multiple of the area. 在本实施例中,每一第二电极11的面积与每一第二类电极1b的面积相同。 In the present embodiment, each of the area of ​​the second electrode 11 and the area of ​​each electrode 1b is the same as the second type. 进一步地,对于每一感应通道单元,多个第一电极10的面积之和与多个第二电极11的面积之和相等。 Further, for each sensing channel unit area of ​​area of ​​the plurality of first electrode 10 and a plurality of second electrodes 11 and equal.

[0042] 进一步地,为了使得两个第一电极10和第二电极11之间的耦合能达到更好的效果,第一电极10和第二电极11可以设置成“工”字型;也可以设置成梳状电极,参考图1b所示,第一电极10的梳状分支与第二电极11的部分梳状分支交叉耦合形成一个互电容感应节点,这样感应通道单元101中的每一互电容感应节点为第一电极10与第二电极11交叉耦合形成的。 [0042] Further, in order that the coupling between the two first electrodes 10 and the second electrode 11 to achieve better results, the first electrode 10 and second electrode 11 may be set to "I" shape; may be comb electrodes arranged, with reference to Figure 1b, the cross-coupled part of the comb electrodes of the first electrode 10 and the second branch 11 forming a comb branch mutual capacitance sensing nodes, each such passage sensing unit 101 of the mutual capacitance sense node is coupled to a first electrode 10 and second electrode 11 is formed crossing.

[0044] 而在实际应用过程中,如果第一电极10和第二电极11的排列方式采用镜像排列方式,即多个并列排布的感应通道单元101两两镜像对称,使得触摸屏体I上电极的图案是左右中心对称,对实现边缘的一致性有很好的帮助。 [0044] In practical applications, if the arrangement of the first electrode and the second electrode 10 using a mirror arrangement 11, i.e., a plurality of parallel arranged channel sensing means 101 twenty-two mirror-symmetrical, so that the touch screen body electrode I the pattern is symmetrical about the center, there is a good help to achieve consistent edge.
