[0094]由于在第一方向上,同一第一电极单元21相邻的两个第一电极部分相对设置,这样在同一第一电极单元21的相邻的两个第一电极中:二者在第一方向上不相对的部分均可以分别与对应的第二电极形成电容感应节点24,该电容感应节点24包括了单个第一电极与第二电极的耦合电容,当触摸在此区域时,单个电容发生改变;同时,二者在第一方向上相对的部分也可以与对应的第二电极形成电容感应节点28,该电容感应节点28则包括了相邻两个第一电极与同一个第二电极的复合耦合电容,当触摸发生在此区域时,两个电容同时发生改变,从而可以区分出触摸位置是在电容感应节点24区域还是电容感应节点28区域, 因此本技术在电极物理尺寸相同的情况下,增加了电容感应节点的数量及类型,提高了触控精度。 [0094] Since in the first direction, the first two parts of the same electrode of the first electrode unit 21 disposed adjacent to the opposite, so that the same two adjacent first electrodes of the first electrode unit 21: in both partially opposite to the first direction can be formed separately from the second electrode of the capacitor corresponding to the sensing node 24, the capacitive sensing node 24 comprises a single first coupling capacitance electrode and the second electrode, when the touch in this region, a single capacitance change; the same time, opposite the first direction in both portions may be formed with a capacitive sensing node 28 corresponding to the second electrode, the capacitive sensing node 28 comprises two adjacent first electrode and a second same composite coupling capacitance electrode, when a touch occurs in this region, while the two capacitors is changed, so that the touch position can be distinguished in the region of the capacitive sensing node 24 or node 28 capacitance sensing region, the present technology in the same physical size of the electrodes case, increasing the number and type of capacitive sensing nodes, the improved accuracy of the touch.

[0097]对于长度为15Pitch (节距)的单层多点互容式触摸屏,如果采用图1所示实施方式,每个第二电极长度为lPitch,一个感应电极组中具有1个第一电极以及15个第二电极, 形成15个电容感应节点12,需要16条走线(1条第一引线14,15条第二引线15)。 [0097] For single multi length 15Pitch (pitch) of mutual capacitance touch screen, if the embodiment shown in Figure 1, the length of the lPitch each second electrode, a sensing electrode assembly having a first electrode and a second electrode 15, 15 form capacitive sensing nodes 12, 16 need traces (14, 15 a second lead of the first lead 15). 对于所有的四个感应电极组:共形成6〇个电容感应节点12、需要64条走线。 For all four sensing electrodes group: forming 6〇 capacitive sensing nodes 12, 64 of traces. 本申请中定义长度为第二方向上的尺寸。 The present application is defined as a length dimension in the second direction. 其中,节距为一个设定的长度值。 Wherein, the pitch is the length of a set value.

[0098]而采用图2所示实施方式,设定一个第二电极长度为2.5Pitch,第1个第一电极与第7个第一电极的长度均为1.5Pitch,其它第一电极的长度为3Pitch,在第一方向上的两个相邻的第一电极之间相对的部分的长度为0.5Pitch。 [0098] The use of the embodiment shown in FIG. 2, a second set of electrode length 2.5Pitch, a length of the first electrode and the first electrode 7 are 1.5Pitch, other lengths of the first electrode is 3Pitch, the length of the portion between the first two electrodes in a first direction relative to the adjacent 0.5Pitch. 此时,总的长度仍为15Pitch。 In this case, the total length remains 15Pitch. 一个感应电极组27中具有七个第一电极以及6个第二电极,形成18个电容感应节点,需要13条走线(7条第一引线26,6条第二引线25)。 A sensing electrode group 27 having a first electrode and a seven second electrode 6 is formed capacitive sensing nodes 18, 13 need traces (7 26,6 second lead of the first lead 25). 对于所有的四个感应电极组27:共形成72个感应节点24、需要52条走线。 For all four sensing electrodes 27 group: total 72 sensing node 24 is formed, traces need to 52. 可见,相对于图1所示的现有结构,图2所示实施例在增加电容感应节点数量的同时,降低了走线的数量,进而降低了绑定垫23的数量以及走线盲区L的宽度。 Seen with respect to the conventional structure shown in FIG. 1, the embodiment shown in FIG. 2 increase in the number of capacitance sensing nodes while reducing the number of traces, thus reducing the amount of binding of the pad 23 and the alignment of the blind L width. 因此降低了成本,并提尚了触控精度。 Thus reducing costs and still put the touch accuracy. 宽度为第一方向上的尺寸。 Width dimension in the first direction. 对于走线盲区L宽度的降低,可以在设定宽度的单层多点互容式触摸屏内设置更多的感应电极组27,进一步提高触控精度。 For reducing the down line width L blind, may be provided in a single layer multi-point set within the width of the mutual capacitance touch screen more sensing electrode group 27, to further improve the accuracy of the touch. 或者说,代替设置更多的感应电极组27,与图2所示单层多点互容式触摸屏的绑定垫23 相贴合的FPC的宽度则会对应减小,从而节省FPC的制造成本,相应地,包括所述单层多点互容式触摸屏和FPC的电子设备131 (见后述图13)的成本较低。 Or, instead of providing additional sensing electrode group 27, and the single multi-point shown in FIG. 2 binding mutual capacitance touch screen pad width of the FPC 23 bonded will correspond reduced, thereby saving the manufacturing cost of the FPC correspondingly, the single layer comprising a low mutual capacitance multi-touch panel and the FPC 131 of the electronic device (described later in FIG. 13) of the cost.

[00"]需要说明的是,上述图2中的各感应电极组27之间呈镜像对称排布,然,所述各感应电极组27之间并不限于呈镜像对称排布,也可以为各感应电极组27的结构相同,彼此之间王阵列式排布。优选地,位于相邻感应电极组27之间区域的引线为同一类型的引线,即, 相邻的感应电极组27之间区域的引线不能既有第一引线况,又有第二引线25,从而减少耦合干扰。 [00 "] Incidentally, mirror-symmetrical arrangement between the sensing electrodes 27 in FIG 2 groups, however, the group is not limited to the sensing electrodes 27 between the mirror-symmetrical arrangement, it may be a the same between the sensing electrodes 27 of the group structure, Wang array arranged between each other. preferably, the lead is located in the region between the sensing electrode 27 adjacent groups of the same type of wire, i.e., 27 groups of adjacent sensing electrodes a first lead wire area can not both cases, there are a second lead 25, so as to reduce interference coupling.

[0100]参,图3,图3为本申请实施例提供的另一种单层多点互容式触摸屏的拓扑结构示意图,图3所示单层多点互容式触摸屏中,具有四个感应电极组27, g卩m=4,第一电极单元21 具有6个第一电极,即n = 6。 [0100] Cf., FIGS. 3, FIG. 3 is a schematic view of the application topology of another embodiment provided by the single multi-point mutual capacitance touch screen embodiment, shown in FIG. 3 single multi-point mutual-capacitance touch panel having four sensing electrode group 27, g Jie m = 4, the first electrode unit 21 having a first electrode 6, i.e., n = 6. 此时,k = n,整个第k个第二电极与部分第n个第一电极相对设置。 In this case, k = n, the k-th entire second electrode and the n-th portion disposed opposite the first electrode. 同一第二电极单元22中,至少部分相邻的第二电极在第一方向上部分相对设置。 The same second electrode unit 22, the second electrode adjacent to at least partially in the first direction disposed opposite portion. 第二电极单元在第二方向上的最后一个第二电极长度较短时,其可以与前一个第二电极在第一方向上不相对设置,如图3所示。 Second electrode unit in the second direction when the second electrode of the last shorter length, which may be a second front electrode is not disposed opposite the first direction, as shown in FIG.

[0101]由图3可以看出,除了形成图2所有的单独第一电极与第二电极耦合电容24、相邻的第一电极与同一第二电极的复合耦合电容28之外,还形成了相邻的第二电极与同一第一电极的复合耦合电容29,因此在电极物理尺寸保持不变的条件下,电容感应节点的数量及类型进一步增加。 [0101] As can be seen from Figure 3, except that a first electrode of all of the individual electrode 2 and the second coupling capacitor 24, the coupling capacitance than the composite adjacent the first electrode and the second electrode of the same 28, are also formed a second electrode adjacent to the first electrode of the same composite coupling capacitor 29, thus maintaining the physical size of the electrodes in the same conditions, the number and type of the sense node capacitance is further increased.

[0102]采用图3方式,在一个感应电极组27中:设定第一个第一电极以及最后一个第一电极的长度均为1 • 5Pitch,其它第一电极长度为3 • f5Pitch,第一方向上两个相邻第一电极相对的长度为〇_5Pitch,并设定最后一个第二电极长度为〇.5Pitch,其它第二电极长度为3Pitch,在第一方向上,相邻两个第二电极相对的部分的长度为〇.5Pitch,单层多点互容式触摸屏总的长度仍为15Pitch。 [0102] The Figure 3 embodiment, a sensing electrode group 27: a first length of the first set and the last electrode of the first electrode are 1 • 5Pitch, other lengths of the first electrode 3 • f5Pitch, first two adjacent first electrodes in a direction opposite to 〇_5Pitch length, and finally a second electrode set 〇.5Pitch length, the length of the second electrode other 3Pitch, in the first direction, of two adjacent two electrodes opposing portion of 〇.5Pitch length, the total length of the single multi-point mutual capacitance touch screen remains 15Pitch. 一个感应电极组27中具有6个第一电极以及6个第二电极,形成2〇个感应节点,需要12条走线(6条第一引线况,6条第二引线25)。 A sensor electrode assembly 27 having a first electrode 6 and the second electrode 6 is formed 2〇 induction nodes need traces 12 (condition 6 first lead, the second lead 25 6). 对于所有的四个感应电极组27:共形成80个电容感应节点、需要仙条走线。 For all four sensing electrodes 27 group: total 80 forming capacitive sensing nodes, the need of traces cents. 同样,相对于图1所示的现有结构,图3所示实施例在增加电容感应节点数量的同时,降低了第一引线26、第二引线25的数量,进而降低了绑定垫23的数量以及走线盲区L的宽度。 Similarly, with respect to the conventional structure shown in Figure 1, the embodiment shown in FIG. 3 increase in the number of capacitance sensing nodes while reducing the first lead 26, the number of the second lead 25, thereby reducing the binding of the pad 23 the number of traces and L is the width of the dead zone. 因此降低了成本,并提高了触控精度。 Thus reducing costs, and improving the accuracy of the touch.
