[0047] 请参照图5A,其绘示出根据图3中单一第一感测电极图案平面示意图。 [0047] Referring to Figure 5A, which shows a schematic plan view illustrating the single first sensing electrode pattern 3 according to FIG. 第一感测电极图案102可具有四个碎形边缘102e,且每一碎形边缘102e (如,由柯克曲线所构成的边缘)由交替排列的矩形突出部及矩形凹口所构成。 First sensing electrode 102 may have four fractal pattern edges 102e, 102e and each fractal edge (e.g., by the edge constituted Kirk curve) is composed of alternately arranged rectangular projecting portion and a rectangular recess. 然而,在其他实施例中,第一感测电极图案102可具有少于或多于四个碎形边缘,且每一碎形边缘的突出部及凹口可具有其他轮廓,例如三角形、半圆形或其他几何形状。 However, in other embodiments, the first sensing electrode pattern 102 may have fewer or more than four fractal edges, and each edge of the projecting portion and the fractal recess may have other profiles, such as triangular, semicircular shaped or other geometric shapes. 可以理解的是当改变第一感测电极图案102的外形轮廓时,需相应改变基底100的感测区101的中心部IOla外形轮廓。 It will be appreciated that when changing the contour of the first sensing electrode pattern 102, the corresponding need to change the contour of the central portion IOla sensing region 101 of the substrate 100.

[0048] 请再参照图3,感测电极层更包括多个电性隔离的第二感测电极图案104以及多个电性隔离的第三感测电极图案106,其中第二感测电极图案104位于感测区101的周围边缘部IOlb (标示于图4),而第三感测电极图案106位于感测区101的周围顶角部IOlc (标示于图4)。 [0048] Referring again to FIG. 3, the sensing electrode layer further comprises a plurality of electrically isolated from the first sensing electrode pattern 104 and a plurality of third sensing electrode patterns 106 electrically isolated, wherein the second sensing electrode pattern peripheral edge portions iOlb 104 located in the sensing region 101 (shown in FIG. 4), while the third sensing electrode pattern 106 is located around the apex portion IOlc sensing region 101 (shown in FIG. 4). 在本实施例中,每一第二感测电极图案104具有至少一碎形边缘,使相邻的第二感测电极图案彼此嵌合,且每一第二感测电极图案104与相邻的第一感测电极图案102也彼此嵌合。 In the present embodiment, each of the second sensing electrode 104 having at least a fractal pattern edge, so that adjacent second sensing electrode pattern fitted to each other, and each of the second sensing electrode pattern 104 and the adjacent first sensing electrode pattern 102 is also fitted to each other. 再者,每一第三感测电极图案106具有至少一碎形边缘,使每一第三感测电极图案106与相邻的第二感测电极图案104彼此嵌合。 Further, each of the third sensing electrode 106 having at least a fractal pattern edge, so that each third sensing electrode pattern 106 and the adjacent second sensing electrode pattern 104 fitted to each other.

[0049] 请参照图5B及图5C,其中图5B是绘示出图3中单一第二感测电极图案平面示意图,而图5C是绘示出图3中单一第三感测电极图案平面示意图。 [0049] Referring to FIG 5B and FIG. 5C, where FIG. 5B is a schematic plan view illustrating the single 3 second sensing electrode pattern showing, and FIG. 5C is a schematic diagram showing the third sensing electrode 3 single pattern plan view . 在本实施例中,第二感测电极图案104可具有三个碎形边缘104e、104f及104g,且第三感测电极图案106可具有二个碎形边缘106e及106f。 In the present embodiment, the second sensing electrode 104 may have a three fractal pattern edge 104e, 104f and 104g, and the third sensing electrode 106 may have two fractal pattern edges 106e and 106f. 碎形边缘104e、104f、104g、106e及106f相似于碎形边缘102e (标示于图5A),由交替排列矩形突出部及矩形凹口所构成。 Fractal edge 104e, 104f, 104g, 106e and 106f similar to the fractal edge 102e (labeled in FIG. 5A), a rectangular protrusion portions alternately arranged and formed a rectangular recess. 因此,在一些实施例中,每一第二感测电极图案104的外形轮廓可相同于每一第一感测电极图案102的局部外形轮廓。 Thus, in some embodiments, each of the second sensing electrode pattern 104 may be identical to the contour of the contour of each of the first local sensing electrode pattern 102. 举例来说,第二感测电极图案104的外形轮廓可相同于第一感测电极图案102的一半外形轮廓。 For example, the contour pattern of the second sensing electrode 104 may be identical to the first sensing electrode pattern 102 of the half contour. 再者,每一第三感测电极图案106的外形轮可相同于每一第二感测电极图案104的局部外形轮廓。 Further, each of the third sensing electrode pattern 106 may be the same round shape in the contour of each of the second local sense electrode pattern 104. 举例来说,第三感测电极图案106的外形轮廓可相同于第二感测电极图案104的一半外形轮廓。 For example, the third sensing electrode pattern 106 may be the same contour in the second half of the sensing electrode contour pattern 104.

[0050] 在其他实施例中,第二感测电极图案104也可具有少于或多于三个碎形边缘,且第三感测电极图案106也可具有少于或多于二个碎形边缘。 [0050] In other embodiments, the second sensing electrode pattern 104 may have fewer or more than three fractal edge, and the third sensing electrode pattern 106 may have less than or more than two fractal edge. 再者,每一碎形边缘的突出部及凹口可具有其他轮廓,例如三角形、半圆形或其他几何形状。 Further, each projecting portion and the edge of the fractal recess may have other profiles, such as triangular, semi-circular, or other geometric shapes. 同样地,可以理解的是当改变第二及第三感测电极图案104及106的外形轮廓时,需相应改变基底100的感测区101的周围边缘部IOlb及周围顶角部IOlc外形轮廓。 Likewise, you are understood that when changing the second and third sensing electrode patterns 104 and 106 of the contour, the need to change the respective peripheral edge portions and around the apex portion IOlc IOlb contour sensing region 101 of the substrate 100.

[0051] 由于感测电极层中第一、第二及第三感测电极图案102、104以及106彼此嵌合,因此当使用者进行操作时,至少二个的感测电极图案可感测到来自使用者的输入信号。 [0051] Since the sensing electrode layer of the first, second, and third sensing electrode patterns 102, 104, 106 and fitted to each other, so when the user operates at least two sensing electrode pattern may be sensed input signal from the user. 如此一来,可有助于外部控制电路(未绘示)辨别输入位置,进而提升触控感测装置200的线性度及灵敏度。 As a result, it can contribute to external control circuit (not shown) to identify an input position, thereby improving the linearity and sensitivity of the touch sensing apparatus 200.

[0052] 然而,由于第二及第三感测电极图案104以及106的感测面积小于第一感测电极图案102的面积,因此第二及第三感测电极图案104以及106所感测的信号强度会低于第一感测电极图案102所感测的信号强度。 [0052] However, since the sensing area of ​​the second and the third sensing electrode pattern 104 and sensing area 106 is less than the first sensing electrode pattern 102, the second and the third sensing electrode patterns 104 and 106 the sensed signal strength is below a signal strength of the first sensing electrode pattern 102 is sensed.

[0053] 为了提升第二及第三感测电极图案104以及106所感测的信号强度,感测电极层更包括多个延伸部104a及106a,如请图3所示。 [0053] In order to improve the second and the third sensing electrode pattern 104 and the signal strength 106 sensed, the sensing electrode layer further comprises a plurality of extension portions 104a and 106a, as shown in FIG. 3 please. 延伸部104a位于周围边缘部IOlb且连接至一对应的第二感测电极图案104,而延伸部106a位于周围顶角部101c,且连接至一对应的第三感测电极图案106。 The peripheral edge portion 104a extending portion IOlb positioned and connected to a corresponding second sensing electrode pattern 104, and the extended portion 106a is located around the apex portion 101c, and connected to a corresponding third sensing electrode pattern 106. 在一实施例中,延伸部104a与对应第二感测电极图案104的面积和相同于第一电极图案102的面积。 In one embodiment, the area corresponding to the area of ​​the extension portion 104a and the second sensing electrode pattern 104 and the first electrode 102 in the same pattern. 再者,延伸部106a与对应第三感测电极图案106的面积和也相同于第一电极图案102的面积。 Furthermore, the area corresponding to the extension portion 106a and the third sensing electrode pattern 106 and in the same area of ​​the first electrode pattern 102.

[0054] 请参照图6A,其绘示出图3中区域A的放大示意图。 [0054] Referring to Figure 6A, which shows an enlarged view of the area A 3 of FIG. 在一实施例中,相邻的第一感测电极图案102之间包括位于感测电极层内的一沟道G,其沿着碎形边缘102e (标示于图5A)延伸,以电性隔离相邻的第一感测电极图案102。 In one embodiment, adjacent to the first sensing electrode pattern 102 includes a channel between the G in the sensing electrode layer, an edge along a fractal 102e (labeled in FIG. 5A) extending, electrically isolated adjacent to the first sensing electrode pattern 102. 亦即,沟道G为用以图案化感测电极层(例如,金属网孔层)的切割道。 That is, G is a channel used to pattern sensing electrode layer (e.g., a metal mesh layer) scribe. 在其他实施例中,相邻的第一感测电极图案102之间可包括至少二个平行沟道(即,双重切割道(未绘示)),以防止导电颗粒(未绘示)在触控感测装置200制造期间落在单一沟道上所引发感测电极图案的短路问题,进而增进触控感测装置200的良率。 In other embodiments, adjacent to the first sensing electrode pattern may comprise at least two parallel channels between 102 (i.e., double scribe lines (not shown)), in order to prevent the conductive particles (not illustrated) in contact 200 falls during manufacture on a single control channel sensing means sensing a short circuit electrode pattern problems arising, and further enhance the yield of the touch sensing apparatus 200.

[0055] 同样地,可以理解的是相邻的第二感测电极图案104之间、每一第一感测电极图案102与对应的第二感测电极图案104之间以及每一第三感测电极图案106与对应的第二感测电极图案104之间可包括位于至少二平行沟道,以电性隔离第一、第二及第三感测电极图案102、104及106。 [0055] Likewise, it is understood that between adjacent second sensing electrode pattern 104, between each of the first sensing electrode pattern 102 corresponding to the second sensing electrode pattern 104 and each of the third sensor measured between the electrode patterns 106 corresponding to the second sensing electrode pattern 104 may comprise at least two parallel channels positioned to electrically isolate the first, second, and third sensing electrode patterns 102, 104 and 106.

[0056] 请参照图6B,其绘示出图3中区域B的放大示意图。 [0,056] Referring to Figure 6B, which shows an enlarged schematic view of region B in FIG. 3. 感测电极层更包括多条走线,用以电性连接对应的第一电极图案102至外部电路(未绘示)。 Sensing electrode layer further comprises a plurality of traces, for electrically connecting the corresponding first electrode pattern 102 to external circuitry (not shown). 此处,为简化附图,仅绘示出单一走线107。 Here, to simplify the drawing, only a single trace plot 107 is shown. 在一实施例中,走线107沿着第二电极图案104的其中一个的碎形边缘延伸至第一电极图案102的其中一个,使第一电极图案102电性连接至外部电路(未绘示)。 In one embodiment, the trace 107 which extends along a second edge of the electrode pattern 104 to the fractal wherein a first electrode pattern 102, the first electrode pattern 102 is electrically connected to an external circuit (not shown ). 然而在其他实施例中,走线107也可沿着第三电极图案106的其中一个的碎形边缘延伸至第一电极图案102的其中一个。 However, in other embodiments, trace 107 may be along one of the third electrode pattern 106 extends to the edge of the fractal wherein a first electrode pattern 102.

[0057] 请再参照图6B所示,走线107的材质可相同于感测电极层。 [0057] Please refer to FIG. 6B, the trace 107 may be identical to the material of the sensing electrode layer. 亦即,可通过图案化一金属网孔层而同时定义出第一、第二及第三感测电极图案102、104及106与走线107。 That is, at the same time may define a first, second, and third sensing electrode patterns 102, 104, and 106 and the trace 107 by patterning a metal mesh layer. 如此一来,可简化工艺及降低制造成本,同时可降低感测电极图案及走线的可视性(visibility)。 Thus, to simplify the process and reduce manufacturing costs, while reducing the sensing electrode pattern and wiring visibility (visibility).

[0058] 根据上述实施例,由于感测电极图案交错排列且具有可彼此嵌合的碎形边缘,因此触控感测装置除了可使用于多点触控操作之外,至少二个感测电极可同时感测来自使用者的输入信号。 [0058] According to the above embodiment, since the sensing electrode pattern and alternately arranged with an edge can be fitted to each other fractal, so in addition to the touch sensing device can be used in addition to multi-touch operation, at least two sensing electrodes You can sense an input signal from a user at the same time. 如此一来,无须通过缩小感测电极图案便可增加触控感测装置的线性度,同时防止布线困难度因感测电极图案的数量增加而上升。 Thus, by reducing the need sensing electrode pattern can increase the linearity of the touch sensing device, while preventing the wiring due to the increasing difficulty of sensing electrode pattern rises.

[0059] 再者,在相同的片电阻(sheet resistance)下,由金属网孔层所形成的感测电极图案的透光度(transmittance)高于由ITO所形成的感测电极图案的透光度。 [0059] Further, in the same sheet resistance (sheet resistance), transparency sensing electrode pattern of a metal mesh layer formed (Transmittance) above the translucent sensing electrode pattern is formed of ITO degree. 因此,触控感测装置200的光学特性优于现有具有ITO感测电极的共平面单层式触控感测装置。 Thus, the optical characteristics of the touch sensing apparatus 200 over the prior co-planar single-layer touch sensor device having a sensing electrode of ITO.
