For instance, the sensing serial 130 of present embodiment comprises a plurality of first sensing serial 130a and a plurality of second sensing serial 130b, and wherein the first sensing serial 130a and the second sensing serial 130b are electrically insulated each other.The first sensing serial 130a extends along a first direction 131a.The second sensing serial 130b extends along a second direction 131b.In the present embodiment, first direction 131a is vertical haply with second direction 131b.In other embodiments, the user can be according to the different designs to the first sensing serial 130a and the second sensing serial 130b, and makes its corresponding first direction and second direction have other direction, and above-mentioned for illustrating, the present invention is not limited to this.
In addition, sensor pad 132 can be to use the transparent conductive material of single or multiple lift structure.For instance, the material of sensor pad 132 for example is to select indium tin oxide, indium-zinc oxide for use, or other suitable material.Present embodiment is with the enforcement example of indium tin oxide as sensor pad 132, but is not limited thereto.
In the present embodiment, bridging line 134 can be identical with patterned conductive layer 136 employed materials, and the material of the two can be to use the metal of individual layer or multilayer structure.For instance, bridging line 134 for example is to select metal or other suitable materials such as silver, copper, tin, lead, hafnium, tungsten, molybdenum, neodymium, titanium, tantalum, aluminium, zinc for use with the material of patterned conductive layer 136.Present embodiment, but is not limited thereto as the bridging line 134 enforcement example with patterned conductive layer 136 with titanium/aluminium/titanium plied timber.Because bridging line 134 is shorter, also can use the transparent conductive material of single or multiple lift structure to substitute.For instance, the alternative material of bridging line 134 for example is to select indium tin oxide, indium-zinc oxide for use, or other suitable material.In addition, also can use the multilayer structure of metal and transparent conductive material to substitute.
In addition, Fig. 1 C illustrates the schematic equivalent circuit into the regional area 150 of Figure 1B, and the resistance R 1 that wherein comprises sensor pad 132 is the equivalent parallel circuit with the resistance R 2 that comprises patterned conductive layer 136.Please also refer to Figure 1B and Fig. 1 C, in the present embodiment, if make colored optical filtering substrates 100 that preferable penetrability can be provided, can reach by the thickness that reduces sensor pad 132, yet the reduced down in thickness of sensor pad 132 but can promote the overall resistance of sensing serial 130.Therefore, colored optical filtering substrates 100 configuration patterned conductive layers 136 are between substrate 110 and sensor pad 132, and patterned conductive layer 136 is on the separated region 122 that shows between the block 124, and with sensor pad 132 storehouses, illustrate as Figure 1B and 1C, to reduce the overall resistance of sensing serial 130.
In the present embodiment, the sheet resistance value of patterned conductive layer 136 (sheet resistance) is lower than the sheet resistance value of sensor pad 132.For instance, when patterned conductive layer is titanium/aluminium/titanium plied timber, and sensor pad 132 is an indium tin oxide, and wherein the thickness of indium tin oxide for example is between 500
～1300
, or be lower than 500
In the present embodiment, the sheet resistance value of patterned conductive layer 136 and the sheet resistance value of sensor pad 132 be than between 1:10～1:2000, so both equivalent slice resistance values of sensor pad 132 and patterned conductive layer 136 can be lower than the sheet resistance value of single sensor pad 132.Thus, when the user contacts colored optical filtering substrates 100, the electric current 132b that sensor pad 132 is produced when being driven, just being suitable for most of ground transmits by patterned conductive layer 136, illustrate as Fig. 1 C, and then reduce the overall resistance of the sensing serial 130 that increases because of the thickness that reduces sensor pad 132.
In addition, because bridging line 134 can be identical with patterned conductive layer 136 employed materials, and the material of the two all for example is to use the metal of individual layer or multilayer structure, therefore, the sheet resistance value of bridging line 134 can be lower than the sheet resistance value of sensor pad 132 equally, thus, also can partly reduce the overall resistance of the sensing serial 130 that increases because of the thickness that reduces sensor pad 132.
What deserves to be mentioned is that in the enforcement kenel that another does not illustrate, sensor pad 132 can be between substrate 110 and patterned conductive layer 136.That is to say that in the below of sensor pad 132, above-mentioned effect similarly can be reached in its top that is disposed at sensor pad 132 to patterned conductive layer 132 except configurable.
In addition, in the present embodiment, each patterned conductive layer 136 is a strip pattern conductive layer, illustrates as Figure 1A.In the embodiment that other does not illustrate, according to user's design requirement, the shape of patterned conductive layer 136 more can be circular or other geometric figure.
In addition, patterned conductive layer 136 is disposed on the second surface 114, and account for the area ratio of separated region can be between 1%～99%, preferably, the width of patterned conductive layer 136 is half of black matrix layer 140 width.For instance, if black matrix width is 30 μ m, then the width of patterned conductive layer 136 preferably is 15 μ m.In addition, when colored optical filtering substrates 100 does not dispose black matrix layer 140, be disposed at the usefulness that patterned conductive layer 136 on the second surface 114 of separated region 122 can be used as shading.At this moment, the area ratio that patterned conductive layer 136 is disposed on the separated region 122 can be as above-mentioned configuration mode, or decides according to user's design, preferably, its configuration mode mainly can be avoided the light leak problem, and then promotes the display quality of colored optical filtering substrates 100.
What deserves to be mentioned is that above-mentioned patterned conductive layer 136 all is disposed on or below the sensor pad, in one embodiment, patterned conductive layer 136 more can be disposed on the separated region position of first surface, with the usefulness as shading.
Hold above-mentionedly, patterned conductive layer 136 more can serve as black matrix layer and show contrast as shading in order to improve except that the problem that can improve the high value that produces because of the penetrability that promotes colored optical filtering substrates 100.
In addition, the kenel that patterned conductive layer 136 is configured on the second surface 114 of substrate 100 can have numerous embodiments, below for two embodiment explanations.
