Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a multi-touch avoidance The touch panel of the ghost point problem. [Prior Art] The touch panel has become a man-machine interface that has attracted attention. In particular, with the advent of multi-touch technology, touch panels can give users a more intuitive operating experience. Multi-touch technology can be subdivided into two types. One is the All Point addressable (APA) technology, which can distinguish the actual position of all touch points, which is the most ideal touch technology. However, in terms of technical implementation, there are considerable technical difficulties in terms of conductive layer planning, line layout or data calculation. The other is Gesture Interaction, which mainly detects and distinguishes multi-touch behaviors such as zooming, dragging, and rotating, and is implemented by Axis Intersect technology. The so-called axis interleaving technique is to perform the processing of the diamond-shaped sensing unit on the conductive layer and the conductive layer in each axial direction is used for detecting the change in capacitance. For example, U.S. Patent Publication No. 2009/0051671 discloses a function of dividing a touch panel into a plurality of areas for multi-touch. FIG. 1 is a schematic diagram of a conventional touch panel for multi-touch. Referring to FIG. 1, when the position P1 and the position P2 are touched, the touch panel 100 receives the signal Sx and the signal Sy. In theory, the position P1 and the position p2^ can be inferred by the signal Sx and the signal Sy touch panel 1 2011 201120716 ^U〇y-1-P-D-020TW 32501twf.doc/n. However, in addition to the coordinates of the position Pi and the position P2, the combination of the signal Sx and the signal Sy also obtains the coordinates of the position gi and the position G2, wherein the position G1 and the position G2 are not actually touched, so it is called "ghost point". In other words, although the touch panel 1 can sense a plurality of touch points, it cannot correctly position the position P1 and the position P2 where the touch panel 1 is actually touched. In order to solve the above problem, the touch panel shown in Fig. 2 is proposed. Referring to FIG. 2, the touch panel 200 has an adjacent first panel area 202 and a second panel area 204. The elements in the first panel area 2〇2 include a plurality of first sensing series 21 相互 and a plurality of second sensing series 220 interlaced with each other. In addition, one end of each of the first sensing series 21A is connected to the first transmission line 230, and one end of each of the second sensing series 220 is connected to the second transmission line 240. The component design in the first panel region 202 and the second panel region 2〇4 is, for example, in a mirror-symmetric relationship. When the position P1 and the position P2 are touched, the first sensing series 210 and the second sensing series 22 in the first panel area 2〇2 only receive the signal generated by the position Lu P2, and the first The first sensing series 210 and the second sensing series 220 in the second panel area 2〇4 only receive the position? 1 generated signal. Thereby, the coordinates of the position P1 and the position P2 can be correctly positioned without the problem of ghost points. However, both the left and right sides of the touch panel 2A need to pre-retain a specific area for the second transmission line 24 〇 layout to make the area of the touch panel 200 that can be touch-sensed reduced. That is to say, the touch panel 200 needs to increase the side width design, and the configuration area of the first sensing series 21 〇 and the first sensing series 220 is limited. 201120716 /Wy-i-r-u-020TW 32501twf.doc/n In addition, the Chinese patent application CN 10133948〇 and cn 101393496 have disclosed the use of signal filtering and time-sharing to solve the problem of ghost points. However, this approach increases the burden of driving the chip. SUMMARY OF THE INVENTION The present invention provides a touch panel to solve the problem of multi-touch. The touch panel includes a substrate and a plurality of boards: a sensing pad. The second sensing series is arranged in the base two bridge wiring package. The second sensing is in the two stems and one s. Wiring, the second direction is connected in series with the second sensing pad. The position is - the first - the sensing pad and the adjacent second sensing pad are adjacent to each other::: two; The pad and the second capacitance value are different. The dipole value, and the first capacitance value and the embodiment of the present invention, the above-mentioned sensing 塾 respectively have a -first area, and are located in the second and the first The sensing 塾 has a second area, 201120716 ^UUy-iPD-020TW 32501twf.doc/n. In one embodiment of the present invention, the first sensing pad and the second sensation in the second first area are The measuring pads respectively have a first shape, and the first sensing pad and the second sensing pad located in the two first regions respectively have a second shape, and the first shape is different from the second shape. For example, One shape and the second shape are respectively, for example, a diamond shape, a hexagon shape, an octagon shape, or a circle shape. In one embodiment of the present invention The touch panel further includes a plurality of external patterns. The external pattern is disposed only in the two first regions. The external pattern is connected to a predetermined potential and electrically insulated from the first sensing series and the second sensing string. The column may also be a ground potential. In one embodiment, each outer pattern is located on one side of one of the first sensing series: and along one of the two first regions - sensing Part of the edge of the pad is disposed. Alternatively, each of the outer patterns is located on the side of the second sensing series, and is disposed along a portion of the edges of the second sensing pads in the second region. The outer pattern may also be disposed along a portion of the edge of the first-sensing pad in the second region and a portion of the edge of the second sensing flaw. In addition, each outer pattern completely surrounds one of the first-sensing (four) edges, recorded In the second section - (4) - the bridge wiring is interlaced with the external pattern. Each external pattern may also completely surround the edge of the second sensing pad and the second bridge in the second zone is interlaced with the external pattern However, (4) external _ can be completely surrounded by Sensing the edge of the pad and the second intractable edge, and the outer pattern intersects the first bridge and the second bridge in the second region." In the embodiment of the invention, the above The touch panel further includes a plurality of connection patterns 'each connection pattern connecting two adjacent external patterns. Even 201120716 zvuy-i-f-D-〇20TW 325〇1^ΐάοο/η The connection pattern and the outer pattern can have the same material. Wiring specials include a continuation pattern. The editorial, even: =: = = outer security, and the two ends of the financial connection are respectively connected to two adjacent external lines with multiple branches to connect to an external diagram respectively, which you only use in the case of connecting lines The material is, for example, metal. θ Meat, the present invention divides the touch area into a plurality of areas, and each of the Ba Gu has different capacitances. 2 When the area _ senses between the 塾, the touch can be easily performed Multi-touch on the panel ^ Ti^Easy to be touched The touch panel of the present invention is not easy to produce ghost points. New Zealand 5 brother, lift ~ = The above features and advantages can be more clearly understood, below The present invention is described in detail below with reference to the accompanying drawings. [Embodiment] (9) The touch panel and the touch control portion of the first embodiment are shown in an enlarged manner. The touch panel 300 includes: two 〇 2. 'Multiple-sensing series 32 () and a plurality of second sensing contending tops. The substrate has at least a touch area, and the touch area is smashed ^ One brother, one district I, and two first-F ττ 々# r T t neighboring configuration. The younger-m' each of the first-region I and the second second-region II phase... In the local target, the touch The area 312 is divided into four quadrants, and the second brother area I is, for example, located in the first and third quadrants, respectively, and the second second area ^ 201120716 /u〇yiPD-020TW 32501twf.doc/n is respectively located in the second And the fourth quadrant. However, in other embodiments, the positions of the "different area I and the second area II can be exchanged with each other, wherein the two first areas I are not adjacent" and the second second areas π are not mutually In addition, the number of the touch areas 312 may be increased or decreased according to the size of the actual product. For example, when the touch panel 300 is designed for a small and medium size, the touch area 312 may have only one and the touch panel 300 is large. The size of the touch area 312 may be two or more. The first sensing series 320 and the second sensing series 330 are disposed on the substrate 310 and located in the touch area 312. The sensing series 32 〇 includes a sensation sensing 322 and a plurality of first bridge wires 324. The first bridge wire 324 is connected in series with the first sensing 塾 322 along a first direction D1. Each second sensing string Column 330 includes a plurality of second sensing pads 332 and a plurality of second bridge wires 334. The second bridge wires 334 are along a The second direction D2 is connected in series with the second sensing pad 332. It is worth mentioning that there is a first between the first sensing pads 322 located in the two first regions j and the adjacent second sensing pads 324. The capacitance value, and each of the first sensing pads 322 and the phase detecting electrodes 324 located in a second region π has a second capacitance value ^, and the first -///cj second capacitance value C2 is different. In the present application, the first sensing pad 322 and the second sensing pad 332 located in the two first regions I respectively have a first area of gossip, and the first sensing in the second second area The pad 322 and the second sensing pad 332 respectively have a second area A2. The first area A1 is different from the second area A2, so the first value is different from the second capacitance value C2. It is worth mentioning that the implementation is that the sensing pads 322, 332 in different regions ι, π have different areas ai, 201120716 zuuy-ir-^-020TW 325 〇ltwf.d〇c/n A2 to reach the first The capacitance value ei is different from the first _, y- 甘 from the recognition of /, music - valley value C2. However, in other embodiments, the first - Γ9 甩 valley value Cl and the second capacitance value C2 are not implemented in other ways. Specifically, in the first - τ jj, , ' _ . I, the distance between the first sensing 塾 322 and the adjacent first sensing pad 332 is closer to eight #, and the device is sensing The pad 322 and the second sensing pad 332 have a longer side length. In the first - ^ ... Ganle area, the first measurement is performed between the 'π and the adjacent second sensing 塾 332 and the edge of the second sensing 塾 332 and the first sensing 塾 322 w Logic burns more New Zealand. Therefore, the first adjacent second sensing pad 332 realizes different first first two values ci in the τ + ... /, in the second region η: the coupling effect of the generated _ combining effect is different. With the second capacitance value C2. The first capacitance value C1 of the oblique (10) Dielectric touch panel T is different from the second capacitance value α. Therefore, the charging time required for the first capacitance value C1 disc-Lee six letter π Xiaole-窀C2 is not- To. The touch panel _ can be used to determine whether the touched position is located in the first area = II by the length of the touch sensing. In this way, you can correctly get the real touched ^ without the problem of ghosts. By way of example, two points are touched. In the conventional design, the signal Sx and the signal Sy sensed by the panel 100 are as shown in FIG. The combination of = Sx and signal Sy simultaneously obtains the coordinates of the position ρι, the position P2 ^ m and the position G2. Therefore, the conventional design often has a problem of distinguishing the position Η, the position P2, the position G1 and the position G2; the point being touched has a ghost point.

具體來說，假設真正被觸碰的只有位置P3與位置 P4 ’兩者都位在第一區I中。觸控面板300會感測到的訊 號Sxl與訊號Syl應該對應於第一電容值C1所需的充電 時間及對應的電容值大小。如果真正被觸碰的是位置1>5 與位置P6，觸控面板300應感測到的訊號Sx2與訊號Sy2 應該對應於第二電容值C2所需的充電時間及對應的電容 值大小。因此’觸控面板300感測到訊號Sx與訊號Sy時， 只要同時藉著充電時間的長短及對應的電容值大小就可以 進一步判斷真正被觸碰的是位於第一區I中的位置P3與位 置P4,或是位於第二區Π中的位置p5與位置p6。換言之， 觸控面板300可以很有效率地辨識出真正的觸碰點而不會 有鬼點的問題。 值得一提的是，在本實施例中，觸控面板3⑻的設計 僅需改變感測塾322與332的面積A2大小就可以有 放地避免鬼點的問題。因此，本實施例的設計不需改變觸 f面板卿原有的製程步驟及線路佈局設計。換言之，本 實施例不需額外增加邊寬而不會使觸控區312的面積受到 為了解決鬼點問題而使第—電容值C1 =同還，由其他的方式來實現。舉例而言：值4 二=之一第二實施例的觸控面板中觸控區的示意 二ϋ:圖4 ’觸控面板_在觸控區412中設置有第 ，、弟二區Π。另外，觸控面板4〇〇包括多條第一感 11 201120716 2009-1-P-D-020TW 32501twf.doc/n 測串列420與多條第二感測串列430。各第一感測串列42〇 包括多個第一感測墊422以及多條第一橋接線424，且第 一橋接線424沿一第一方向D1串接第一感測墊422。各第 一感測串列430包括多個-第二感測墊432以及多條第二橋 接線434’且第二橋接線434沿一第二方向D2串接第二感 測墊432。 〜 觸控面板300與觸控面板400的設計大致相同。不 過’觸控面板400實現第一電容值^與第二電容值C2$ 同的方式是使位於二第一區I中的第一感測墊422與第二 感測墊432分別具有一第一形狀，而位於二第二區π'中的 第一感測墊422與第二感測墊432分別具有一第二形狀， 且弟t狀與苐一形狀不同。舉例而言，第一形狀與第二 形狀分別例如為一菱形、一六邊形、一八邊形或一圓形其 中之二。 〃 在本貫施例中，第一形狀例如為六邊形而第二形狀例 如為曼形。也就是說，第一區j中的所有感測墊422與 都，六邊形的圖案，而第二區IIt的所有感測墊422與432 都疋菱形圖案。相鄰的六邊形圖案之間的距離與相鄰菱形 圖，之間的距離不同。因此，第一區！中第一感測塾422 與，二感測墊432之間的第一電容值Cl不同於第二區Η 中第一感測墊422與第二感測墊432之間的第二電容值 C2。藉著這樣的設計，觸控面板400可以透過電容的充電 時間來判斷多點觸控時真正觸控點的位置。亦即，觸控= 板400可以有效地避免鬼點的問題。 12 2〇ii2〇Zii_TW 32501twf.doc/n 為了實現第一電容值Cl與第二電容值C2不同的設 計，上述第一區I中的元件設計可以有以下多種變化。 圖5繪示為本發明之一第三實施例的觸控面板中觸控 區的第一區的元件設計。請參照圖5，觸控面板500包括 多條第一感測串列520以及多條第二感測串列530。各第 一感測串列520由第一感測墊522與第一橋接線524所組 成’而各第二感測串列530由第二感測聲532與第二橋接 線534所紅成。在本實施例中，所有的第一感測墊522與 •第二感測墊532都具有相同的面積及形狀。也就是說，無 論在第一區I或第二區II中，第一感測墊522與第二感測 墊532的圖案設計為相同的。 此外，觸控面板500中觸控區512的第一區I更設置 有多個外部圖案540。外部圖案540連接至一預設電位v 並電性絕緣於第一感測串列52〇與第二感測串列53〇。在 一實施例中，預設電位V可以為一接地電位或其他固定的 電位。藉由這樣的設計，各第一感測墊522與相鄰的第二 鲁 感測墊532之間的耦合效應會受到外部圖案540的影響而 達到第—區I與第二區π中第一感測塾522與第二感測塾 53：^間具有不同電容的效果。也就是說，觸控面板獅可 以藉由電容的充電時間長短來躺觸碰位置是在第一區j 或第二區II以避免鬼點的問題。 在本實施例中，各外部圖案540位於 測㈣52〇的一側，並沿第一區！中的其中一個第== 塾522的部伤邊緣配置。且㈣忠％ 咏 直吳脰來况，弟一感測墊522的圖 13 201120716 /uuv-i-r-u-020TW 32501twf.doc/n 案設計例如是菱形，則各外部圖案54〇例如是“〉，，形或是 “< ”形。每一個第一感測墊522例如被兩個分別為 與形的外部圖案540包圍。因此，第一感測墊522除 -了會與第二感測墊532之間產生耦合作用外，還會與外^ 圖案540產生耦合作用以構成特定的電容。 詳言之，為了將所有的外部圖案54〇連接至預設電位 V，觸控面板500更包括多個連接圖案55〇以及一連接線 路560。各連接圖案550連接相鄰兩個上述之外部圖案 540,也就是說各連接圖案550連接相鄰兩個且分別為“>二 形與“〈”形的外部圖案540。連接線路56〇則與上述的外 部圖案540連接，以將預設電位ν輸入至外部圖案54〇。 具體而言，連接線路560可以包括多條連接線562以及— 梳形線路564。各連接線562的兩端分別連接於相鄰兩個 外部圖案540，而梳形線路564具有多個分支568以分別 連接至一個外部圖案540。 另外’連接圖案550與外部圖案540可以具有相同的 材質。亦即’連接圖案550與外部圖案540可以由相同的 製程加以製作。舉例而言，連接圖案550與外部圖案540 的材質例如是透明導電材質。在一實施例中，第一感測塾 522與第二感測墊532也可以由透明導電材質製作而成。 所以，連接圖案550與外部圖案540可以在製作第一感測 整522與第二感測墊532時一併製作。當然，本發明並不 限定於將連接圖案550、外部圖案540、第一感測墊522 與第二感測墊532 —併製作 14 201120716 ,uuy-i-P-D-020TW 325〇]twfd〇c/n 連接線路560的材質則例如為金屬，以達到較佳的電 傳輸致果。本實施例也可以採用金屬製作第二橋接線 532。所以，連接線路56〇也可以與第二橋接線532 一併製 作。換言之，本實施例的外部圖案540、連接圖案55〇以 及連接線路560可以整合於觸控面板500原有的製作方式 中加以製作。這樣的設計不會增加製程步驟，又可以達到 避免鬼點的觸控感測。 φ 。圖6繪示為本發明之一苐四實施例的觸控面板中觸控 區的第一區的元件設計。請參照圖6，觸控面板6〇〇的設 计與觸控面板500大致相同，因此兩實施例中相同的元件 符號代表相同的元件。不過，觸控區612的第一區j中， 外部圖案640位於其中一條第二感測串列53〇的一侧，並 沿第一區I中的其中一個第二感測墊532的部份邊緣配 置。也就是說’本實施例的外部圖案640具有形以及 形的圖案設計。相似地，外部圖案64〇連接至預設電 位v而可以改變第一區ϊ中第一感測墊522與第二感測墊 • 532之間的電容。如此，觸控面板6〇〇便可以達到避免鬼 點感測的設計。 圖7繪示為本發明之一第五實施例的觸控面板中觸控 區的第一區與第二區的元件設計。請參照圖7，本實施例 的第一區I中元件設計例如是整合了前述第三實施例與第 四貫施例的概念，也就是說，這些外部圖案74〇沿著第一 區I中的第一感測墊522的部份邊緣以及第二感測墊532 的部份邊緣配置。因此，第一區i中第一感測墊522與第Specifically, it is assumed that only the position P3 and the position P4' are actually located in the first zone I. The signal Sx1 and the signal Syl that the touch panel 300 senses should correspond to the charging time required by the first capacitance value C1 and the corresponding capacitance value. If the position 1 > 5 and the position P6 are actually touched, the signal Sx2 and the signal Sy2 that the touch panel 300 should sense should correspond to the charging time required by the second capacitance value C2 and the corresponding capacitance value. Therefore, when the touch panel 300 senses the signal Sx and the signal Sy, it can be further judged that the position P3 located in the first area I is actually touched by the length of the charging time and the corresponding capacitance value. Position P4, or position p5 and position p6 in the second zone. In other words, the touch panel 300 can efficiently recognize the true touch point without the problem of ghosts. It should be noted that in the present embodiment, the design of the touch panel 3 (8) only needs to change the size of the area A2 of the sensing electrodes 322 and 332 to avoid the problem of ghost points. Therefore, the design of the embodiment does not need to change the original process steps and circuit layout design of the panel. In other words, the embodiment does not need to additionally increase the side width without causing the area of the touch area 312 to be affected by the ghost point problem so that the first capacitance value C1 = the same, which is realized by other means. For example, the value of the touch panel of the touch panel of the second embodiment is as follows: FIG. 4 'The touch panel _ is disposed in the touch area 412 with the first and second sections. In addition, the touch panel 4 includes a plurality of first senses 11 201120716 2009-1-P-D-020TW 32501twf.doc/n the series 420 and the plurality of second sensing series 430. Each of the first sensing series 42A includes a plurality of first sensing pads 422 and a plurality of first bridge wires 424, and the first bridge wires 424 are connected in series with the first sensing pads 422 along a first direction D1. Each of the first sensing series 430 includes a plurality of - second sensing pads 432 and a plurality of second bridge wires 434' and the second bridge wires 434 are connected in series with the second sensing pads 432 in a second direction D2. ~ The touch panel 300 is substantially the same as the design of the touch panel 400. However, the manner in which the touch panel 400 realizes the first capacitance value and the second capacitance value C2$ is such that the first sensing pad 422 and the second sensing pad 432 located in the two first regions I have a first The shape of the first sensing pad 422 and the second sensing pad 432 in the second and second regions π′ respectively have a second shape, and the shape of the t-shape is different from the shape of the first one. For example, the first shape and the second shape are respectively, for example, a diamond, a hexagon, an octagon, or a circle.本 In the present embodiment, the first shape is, for example, a hexagon and the second shape is, for example, a man. That is to say, all of the sensing pads 422 in the first region j have a hexagonal pattern, and all of the sensing pads 422 and 432 of the second region IIt have a diamond pattern. The distance between adjacent hexagonal patterns is different from the distance between adjacent diamond patterns. So the first district! The first capacitance value C1 between the first sensing 塾422 and the second sensing pad 432 is different from the second capacitance value C2 between the first sensing pad 422 and the second sensing pad 432 in the second region Η . With such a design, the touch panel 400 can determine the position of the real touch point during multi-touch by the charging time of the capacitor. That is, the touch=board 400 can effectively avoid the problem of ghost points. 12 2〇ii2〇Zii_TW 32501twf.doc/n In order to realize a design in which the first capacitance value C1 is different from the second capacitance value C2, the element design in the first region I described above can be variously changed as follows. FIG. 5 is a diagram showing the component design of the first region of the touch region in the touch panel according to the third embodiment of the present invention. Referring to FIG. 5, the touch panel 500 includes a plurality of first sensing series 520 and a plurality of second sensing series 530. Each of the first sensing series 520 is formed by the first sensing pad 522 and the first bridge 524, and each of the second sensing series 530 is reded by the second sensing sound 532 and the second bridge 534. In this embodiment, all of the first sensing pads 522 and the second sensing pads 532 have the same area and shape. That is, the pattern of the first sensing pad 522 and the second sensing pad 532 is designed to be the same whether in the first zone I or the second zone II. In addition, the first area I of the touch area 512 in the touch panel 500 is further provided with a plurality of outer patterns 540. The external pattern 540 is connected to a predetermined potential v and electrically insulated from the first sensing series 52A and the second sensing series 53A. In one embodiment, the predetermined potential V can be a ground potential or other fixed potential. With such a design, the coupling effect between each of the first sensing pads 522 and the adjacent second Lu sensing pads 532 is affected by the external pattern 540 to reach the first of the first region I and the second region π. Sensing 塾 522 and second sensing 塾 53: ^ have different capacitance effects. That is to say, the touch panel lion can lie in the first zone j or the second zone II by the charging time of the capacitor to avoid the problem of ghost points. In this embodiment, each of the outer patterns 540 is located on the side of the (four) 52 , and along the first zone! One of the == 塾522 is in the edge of the injury.

Each of the first sensing pads 522 is surrounded, for example, by two external patterns 540, respectively. Therefore, the first sensing pad 522 is separated from the second sensing pad 532. In addition to the coupling effect, it also couples with the outer pattern 540 to form a specific capacitor. In detail, in order to connect all the outer patterns 54A to the preset potential V, the touch panel 500 further includes a plurality of connection patterns. 55〇 and a connecting line 560. Each connecting pattern 550 connects two adjacent outer patterns 540, that is, each connecting pattern 550 connects adjacent two and is respectively "> two-shaped and "-" shaped external Pattern 540. The connection line 56 is connected to the above-described external pattern 540 to input a preset potential ν to the external pattern 54A. In particular, the connection line 560 can include a plurality of connection lines 562 and a comb line 564. Two ends of each of the connecting lines 562 are respectively connected to the adjacent two outer patterns 540, and the comb line 564 has a plurality of branches 568 to be respectively connected to one outer pattern 540. Further, the connection pattern 550 and the outer pattern 540 may have the same material. That is, the 'connection pattern 550 and the outer pattern 540 can be made by the same process. For example, the material of the connection pattern 550 and the outer pattern 540 is, for example, a transparent conductive material. In an embodiment, the first sensing electrodes 522 and the second sensing pads 532 may also be made of a transparent conductive material. Therefore, the connection pattern 550 and the outer pattern 540 can be produced together when the first sensing 522 and the second sensing pad 532 are formed. Of course, the present invention is not limited to connecting the connection pattern 550, the outer pattern 540, the first sensing pad 522 and the second sensing pad 532 - and making 14 201120716 , uuy-iPD-020TW 325 〇] twfd 〇 c / n connection The material of the line 560 is, for example, metal to achieve better electrical transmission. In this embodiment, the second bridge wire 532 can also be made of metal. Therefore, the connection line 56A can also be fabricated together with the second bridge line 532. In other words, the external pattern 540, the connection pattern 55A, and the connection line 560 of the present embodiment can be integrated into the original manufacturing method of the touch panel 500. Such a design does not increase the number of process steps, but also achieves touch sensing that avoids ghost points. φ. 6 is a diagram showing the component design of the first region of the touch region in the touch panel according to a fourth embodiment of the present invention. Referring to FIG. 6, the design of the touch panel 6A is substantially the same as that of the touch panel 500. Therefore, the same component symbols in the two embodiments represent the same components. However, in the first region j of the touch region 612, the external pattern 640 is located on one side of one of the second sensing series 53A, and along a portion of the second sensing pad 532 in the first region I. Edge configuration. That is to say, the outer pattern 640 of the present embodiment has a shape and a shape design. Similarly, the external pattern 64A is connected to the preset potential v to change the capacitance between the first sensing pad 522 and the second sensing pad 532 in the first region. In this way, the touch panel 6 can achieve a design that avoids ghost sensing. FIG. 7 is a diagram showing the component design of the first area and the second area of the touch area in the touch panel according to the fifth embodiment of the present invention. Referring to FIG. 7, the component design in the first region I of the embodiment is integrated with the concepts of the foregoing third embodiment and the fourth embodiment, that is, the external patterns 74 are along the first region I. A portion of the edge of the first sensing pad 522 and a portion of the edge of the second sensing pad 532 are disposed. Therefore, the first sensing pad 522 and the first in the first region i
