When the user touches the touch panel with a finger, the first sensing pad 122 and the second sensing pad respectively form a capacitance with the finger at the position touched by the user, thereby causing the first sensing series 12〇 and the change in the signal on the second sensing train 130. Therefore, by detecting the change of the signal on the first sensing series 120 and the second sensing series 130, 'the position touched by the user can be positioned. The size of the touch panel 100 is gradually increased, and the length of the sensing series on the touch panel is gradually increased. In this way, the line impedance of the first sensing series 120 in the first direction D1 or the line impedance of the second sensing series 130 in the second direction D2 is also increased. The operational sensitivity of the touch panel 100 is thus reduced. In particular, the first sensing pad 122 and the second sensing pad 132 are made of a transparent conductive material such as indium tin oxide. Fig. 1C is a graph showing the relationship between the thickness of indium tin oxide and the surface resistance and the transmittance. Referring to Figure 1C, the thickness of the indium tin oxide is approximately inversely proportional to the transmission impedance. Therefore, in the prior art, the line impedance problem of the touch panel 100 can be improved by increasing the thickness of the first sensing pad 122 and the second sensing pad 132. However, as the thicknesses of the first sensing pad 122 and the second sensing pad 132 increase, the transparency of the touch panel 1 却 decreases, as shown by the thickness of the indium tin oxide in FIG. 1C versus the transmittance. In this regard, Chinese Patent Application No. 200710138674 and U.S. Patent No. 201109774 2009-I-P-D-008TW 31917twf.doc/n Open No. US2__ Brain Phase proposes a method of reducing the transmission impedance of the touch panel. However, the Chinese Patent Application No. 2〇〇71〇138674 has a limitation on the transmittance of the touch panel, and the process thereof is relatively complicated. U.S. Patent Publication No. US 2 〇〇 9 〇〇 85 891 can reduce the resistance limit ′ and its bilateral drive increases the electrode lead, thereby increasing the area of the domain. ^ It can be seen that how to make the touch panel have good sensitivity and high transparency at the same time, which is a key issue for the bribery: [Invention] The present invention provides a touch panel capable of simultaneously having low conductive impedance and good transparency. The present invention provides a touch panel that is adapted to be disposed on a display panel. The touch panel includes a plurality of second sensing series and a plurality of auxiliary line segments. A plurality of -_ series are arranged on the substrate and are parallel to each other. A plurality of second-strings are arranged on the substrate and parallel to each other. The first-J series and the plurality of second sensing series include a multi-pad, a first connection line, and a plurality of second connection lines. The plurality of first connecting lines are parallel to the sensing of the first direction (four) connecting portion to form a == the plurality of second connecting lines are parallel to the second direction and are connected in series with the other sensing electrodes to form the second Sensing the series. Wherein, the first sensing 塾 is coplanar with the f two frequency, and the first connecting line is electrically insulated from the second connecting line segment within the sensing 塾 wheel gallery' and the auxiliary line segment is directly in contact with the sensing 塾. In an embodiment of the invention, in the touch panel, the line width of the auxiliary line segment is 〇π〇πι. The first connecting line and the auxiliary part are the same film layer, and the second connecting line and the sensing pad are the same film layer. A portion of the auxiliary line segment connects the two adjacent first connecting lines. In one embodiment of the invention, the touch panel described above, wherein the auxiliary line segment exists only in the first sensing series or only in the second sensing series. In an embodiment of the invention, in the above touch panel, the auxiliary line segments are simultaneously present in the first sensing series and the second sensing pad series. In one embodiment of the invention, the touch panel further includes a dielectric layer between the first connection line and the second connection line to electrically insulate the first connection line from the second connection line. The touch panel further includes a protective layer disposed on the substrate and covering the first sensing series and the second sensing series. In an embodiment of the invention, in the touch panel, the material of the sensing germanium is a transparent conductive material, and the transparent conductive material comprises a tin oxide or an indium zinc oxide. The material of the auxiliary line segment may be a metal such as: aluminum, tantalum, chrome, aluminum-molybdenum laminate, laminate of aluminum tantalum and molybdenum or a combination thereof. In an embodiment of the invention, the display panel has a black matrix pattern including a plurality of horizontal lines parallel to the first direction and a plurality of parallel lines in the second direction to define a plurality of pixel regions, domains Helpline: Matrix patterns overlap. According to the above, since the touch panel of the present invention is provided with a plurality of auxiliary line slaves, the conductive impedance is smaller than the sensing pad, so the present invention can reduce the conductive impedance of the touch panel king. In some embodiments, the auxiliary line segment can be set to 201109774 2009-IPD-008TW 31917twf.doc/n and placed on the black moment of the display panel. Therefore, when the display panel is placed on the display panel, the touch panel of the county is affected. The above features and advantages of the present invention can be further described with reference to the accompanying drawings, as well as the detailed description of the present invention. First Embodiment FIG. 2 is a touch panel and a display intention according to a first embodiment of the present invention. 3 is a partial top plan view of the touch panel of FIG. 2. Figure 4 is a cross-sectional view of the line taken along line Β-Β in Figure 3. Figure 4 is a cross-sectional view taken along line C-C' of Figure 3. Fig. 4C is a cross-sectional view taken along line D_D of Fig. 3, not intended. Referring to FIG. 2 and FIG. 3 simultaneously, the touch panel 202 is adapted to be disposed on the display panel 204, wherein the display panel 204 is, for example, a liquid crystal display panel. The touch panel 202 includes a substrate 210, a plurality of first sensing series 220, a plurality of second sensing series 230, and a plurality of first auxiliary line segments 252. In the present embodiment, the substrate 210 may be a rigid substrate or a flexible substrate. For example, the hard substrate may be a glass substrate or a stone substrate, and the material of the flexible substrate is, for example, polyethylene terephthalate (PET) or polyethylene naphthalate (PEN). ), polyester (PES), polymethylmethacrylate (PMMA), polycarbonate (PC) or polyimide (PI) 〇201109774 2009-IPD-008TW 31917 twf.doc/n Referring to FIG. 3, a plurality of first sensing series 22 are disposed on the substrate 210 and parallel to each other, and each of the first sensing series 22 includes a plurality of first sensing pads 222 and a plurality of First connection lines 224. Taking one of the first sensing series 220 as an example, the plurality of first connecting lines 224 are parallel to the first direction Di and are connected in series with the plurality of first sensing electrodes 222. In order to make the touch panel 202 have good transparency, the material of the first sensing pad 222 can be selected, for example, from a transparent conductive material such as indium tin oxide or indium zinc oxide. φ The plurality of second sensing series MOs are disposed on the substrate 210 and are parallel to each other, and each of the second sensing series 230 includes a plurality of second sensing electrodes 232 and a plurality of first connecting lines 234. In any of the second sensing series 23A, the plurality of second connecting lines 234 are parallel to the second direction D2 and are connected in series with the plurality of second sensing pads 232. For the same reason, the material of the second sensing pad 232 can also be the same transparent conductive material as the first sensing device 222. A plurality of first auxiliary line segments 252 are located within a contour of the plurality of first sensing pads 222 and are parallel to the first direction D1. In this embodiment, a portion of the first auxiliary line segment 252 connects the two adjacent first connecting lines 224. That is, the first auxiliary line segment M2 of the # portion is connected to the first connecting line 224 as a continuous long wire. 4A and 4B, the first sensing pad 222 and the second sensing pad 232 are coplanar. That is, the first sensing pad 222 and the second sensing pad 232 are, for example, the same film layer on the substrate 21 , and the first sensing pad 222 and the first sensing pad 232 can be simultaneously formed on the substrate 21〇. Above. In the present embodiment, the second connection line 234 spans the first connection line 224 , and the first connection line 224 is electrically insulated from the second connection line 234 . More specifically, 201109774 2009-IPD-008TW 31917twf.doc/n, the touch panel 202 can have, for example, a plurality of dielectric patterns 226 between the first connection line 224 and the second connection line 234 to make the first connection Line 224 is electrically insulated from second connection line 234. Referring to FIG. 4C1, the first auxiliary line-segment 252 is here directly in contact with the first sensing pad 222, and the first connecting line 224 and the first auxiliary line segment 252 may be the same film layer. In one embodiment, the first connection line and the first auxiliary line segment 252 are simultaneously formed on the substrate 210 after being patterned from the same conductive material film layer. In addition, the second connecting line 234 is the same film layer as the first and second sensing electrodes 222, 232. The material of the first auxiliary line segment 252 is, for example, a metal such as aluminum, molybdenum, chromium, aluminum-molybdenum laminate, aluminum laminate and molybdenum laminate or a combination thereof. In particular, the conductive impedance of the first auxiliary line segment 252 is lower than the conductive impedance of the first and second sensing pads 222, 232. As a result, the average conductive impedance on the first sensing series 22〇 will be reduced by the first auxiliary line segment 252 having a lower conductive impedance. In other words, the conductive impedance on the first sensing series 220 can be adjusted by the first auxiliary line segment 252, thereby improving the operational sensitivity of the touch panel 2〇2. On the other hand, since the first auxiliary line segment 252 having a low conductive impedance is mostly made of a material such as metal that is opaque, in order to reduce the influence of the first auxiliary line segment 252 on the overall transparency of the touch panel 202, The line width W1 of the first auxiliary line segment 252 is limited to an appropriate two range. Within this appropriate line width range, the first auxiliary line segment 252 can have a good conductive impedance 'and also; |; will affect the transparency of the touch panel 202. 201109774 2009-I-P-D-008TW 31917twf.d〇c/n In the present embodiment, the line width W1 of the first auxiliary line segment 252 is, for example, less than 30 μm, but is not limited thereto.

Referring to FIG. 6A and FIG. 6B, the touch panel 302 has all the components of the touch panel 202 in the above embodiment, wherein the same components are denoted by the same reference numerals and will not be repeated here. Similarly, in the touch panel 302, the plurality of first auxiliary line segments 252a are located within the contour range of the plurality of first sensing pads 222 and parallel to the first direction D1 ' and the first auxiliary line segment 252a directly contacts the first sensing pad. 222. However, the touch panel 302 is different from the touch panel 202 in that the first auxiliary line segment 252a does not directly connect two adjacent first connection lines 224, and the first auxiliary in the touch panel 3〇2 The layout design of the line segment 252 & is also different from the touch panel 202. Specifically, the number of the first auxiliary line segments 252a on the touch panel 302 may be greater than the number of the first auxiliary line segments 252 on the touch panel 202. Alternatively, the shape of the first auxiliary line segment 252a on the touch panel 3〇2 may be different from the first auxiliary line segment 252 on the touch panel 2〇2. Of course, the first auxiliary line segment 252 can also have other different changes, 12 201109774 2009-I-P-D-008TW 31917twf.doc/n This part can be appropriately changed according to the needs of the user.

In the present embodiment, the second auxiliary line segment 452 and the first auxiliary line segment 252 are the same film layer. The second auxiliary line segment 452 and the first auxiliary line segment 252 can be formed, for example, on the substrate 2i. Similarly, in order to make the touch panel 402 have better light transmittance, the line width W2 of the second auxiliary line segment 452 can be limited to an appropriate range in 201109774 2009-IPD-008TW 3I917twf.doc/n. . In the present embodiment, the line width W2 of the second auxiliary line segment 452 is, for example, less than 30 qing, but this is the secret.
