柔性觸控面板結構Flexible touch panel structure

本創作有關於一種觸控面板結構及其製造方法，且特別是一種柔性觸控面板結構與其製造方法。The present invention relates to a touch panel structure and a method of fabricating the same, and more particularly to a flexible touch panel structure and a method of fabricating the same.

近年來隨著觸控面板的技術發展，觸控面板已廣泛地運用於各類電子產品中，例如手機、手提電腦以及掌上型電腦等。觸控面板一般會與顯示螢幕相整合，以作為電子產品的輸入輸出介面，達到觸控顯示功能。據此，使用者可透過觸控顯示螢幕控制電子設備，對應操控電子設備之功能。In recent years, with the development of touch panel technology, touch panels have been widely used in various electronic products, such as mobile phones, laptop computers, and palmtop computers. The touch panel is generally integrated with the display screen to serve as an input and output interface of the electronic product to achieve a touch display function. Accordingly, the user can control the electronic device through the touch display screen, and correspondingly control the function of the electronic device.

現行觸控面板的結構是利用異向性導電膠(Anisotropic conductive film，ACF)將具觸控感測電路引線的導電薄膜與具後端引線電路的可撓式軟性印刷電路板(Flexible Print Circuit Board，FPC)等兩個不同元件藉由壓合製程工序相結合。藉此，以將觸控感測電路的引線與軟性印刷電路板上相對應的引線電路相連。從而於軟性印刷電路板的引線電路與後端連接器相接時，可將感測信號傳至後端偵測判斷電路。The current touch panel structure is an electrically conductive film with a touch sensing circuit lead and a flexible printed circuit board with a back end lead circuit using an anisotropic conductive film (ACF). , FPC) and other two different components are combined by a press process. Thereby, the leads of the touch sensing circuit are connected to the corresponding lead circuits on the flexible printed circuit board. Therefore, when the lead circuit of the flexible printed circuit board is connected to the back end connector, the sensing signal can be transmitted to the back end detection judging circuit.

目前壓合製程工序至少包含異向性導電膠的貼覆工序、熱壓工序等。然而，習知每經過一道製程工序，對於觸控面板成品都將有可能造成損耗。舉例來說，異向性導電膠因壓合溢膠或是熱壓時異向性導電膠導電粒子未被壓破造成斷路或聚集某處而造成短路或斷路等問題。而隨著觸控顯示螢幕的控制功能的增加，所需 引線電路也越來越多，相對的線路密度越來越高，從而更會增加上述問題的發生頻率，進而增加材料消耗成本並降低良率。At present, the press-bonding process includes at least an attaching process of an anisotropic conductive paste, a hot pressing process, and the like. However, it is known that every time a process is performed, there will be a possibility of loss to the finished touch panel. For example, if the anisotropic conductive adhesive is pressed or melted, the conductive particles of the anisotropic conductive adhesive are not crushed to cause an open circuit or a certain place to cause a short circuit or an open circuit. And as the control function of the touch display screen increases, it is required There are more and more lead circuits, and the relative line density is getting higher and higher, which increases the frequency of the above problems, thereby increasing the material consumption cost and reducing the yield.

The direction (for example, the X axis) protrudes to the left or right side of the touch sensing unit 10. Similarly, as shown in FIG. 1 , although the extending portion 20 protrudes from a substantially central position on the upper side of the touch sensing portion 10 , the extending portion 20 may protrude from the upper side of the touch sensing portion 10 according to actual product design requirements. The position on the right or left side is not limited in this embodiment.

另外，於此實施例中延伸部20的形狀實質上呈矩形狀，但於實務上，延伸部20的形狀可依據實際產品應用需求而設計。舉例來說，延伸部20的形狀可設計為方形、矩形、螺旋形狀、L形狀、S形狀或其他任何幾何形狀，故本實施例並未以此為限。In addition, in this embodiment, the shape of the extending portion 20 is substantially rectangular, but in practice, the shape of the extending portion 20 can be designed according to actual product application requirements. For example, the shape of the extension portion 20 can be designed as a square, a rectangle, a spiral shape, an L shape, an S shape, or any other geometric shape, and the embodiment is not limited thereto.

更詳細地說，於此實施中，柔性觸控面板1為單面觸控面板。換言之，線路佈局僅配置於觸控感測部10以及延伸部20的其中 一面。觸控感測部10上可區分為觸控感測區域110與周邊區域120。所述周邊區域120具有出線口位置30且位於觸控感測區域110的外圍。具體來說，於此實施中，延伸部20突出於觸控感測部10的一側且對應該周邊區域120的出線口位置30。在觸控感測部10上相對於觸控感測區域110內可佈設有一感測電極層111。感測電極層111可以為多條相互交錯排列之感測電極軸(未繪示)，且每條感測電極軸彼此相互絕緣。每一條感測電極軸另包括多個電性連接之感測電極(未繪示)。感測電極可依據實際電路設計需求為多邊形狀區塊，例如方形、長方形、菱形、三角形、六邊形或八邊形等，本實施例並不限制。另，感測電極層111根據實際產品需求也可佈設多條相互平行之條狀感測電極軸，且每條感測電極軸彼此相互絕緣，故本實施例並不限制。In more detail, in this implementation, the flexible touch panel 1 is a single-sided touch panel. In other words, the line layout is only disposed in the touch sensing portion 10 and the extension portion 20 one side. The touch sensing unit 10 can be divided into the touch sensing area 110 and the peripheral area 120. The peripheral area 120 has a wire exit position 30 and is located at the periphery of the touch sensing area 110. Specifically, in this implementation, the extension portion 20 protrudes from one side of the touch sensing portion 10 and corresponds to the outlet port position 30 of the peripheral region 120. A sensing electrode layer 111 is disposed on the touch sensing portion 10 relative to the touch sensing region 110. The sensing electrode layer 111 may be a plurality of sensing electrode axes (not shown) that are staggered with each other, and each sensing electrode axis is insulated from each other. Each of the sensing electrode shafts further includes a plurality of electrically connected sensing electrodes (not shown).

The embodiment is not limited. In addition, the sensing electrode layer 111 can also be disposed with a plurality of mutually parallel strip-shaped sensing electrode shafts according to actual product requirements, and each sensing electrode axis is insulated from each other, so the embodiment is not limited.

在觸控感測部10上相對於周邊區域120內佈設有多條第一導線121，並該些第一導線121分別電性連接感測電極層111。也就是說，該些第一導線121的第一端分別由周邊區域120延伸至觸控感測區域110以電性連接感測電極層111。該些第一導線121於周邊區域120內形成周邊引線線路。另外，所述第一導線121的數量可根據感測電極層111的實際需求來佈設。A plurality of first wires 121 are disposed on the touch sensing portion 10 relative to the peripheral region 120 , and the first wires 121 are electrically connected to the sensing electrode layer 111 . In other words, the first ends of the first wires 121 extend from the peripheral region 120 to the touch sensing region 110 to electrically connect the sensing electrode layer 111 . The first wires 121 form peripheral lead lines in the peripheral region 120. In addition, the number of the first wires 121 may be arranged according to actual needs of the sensing electrode layer 111.

而延伸部20上另區分為引線區域210與引腳區域220。在延伸部20上相對於引線區域210內佈設有多條第二導線211，其中該些第二導線211彼此平行且相互絕緣。在延伸部20上相對於引腳區域220內則佈設多個彼此電性絕緣之引腳221。該些第二導線211的第一端分別電性連接該些引腳221，而該些第二導線211的第二端電性連接該些對應的第一導線121的第二端。The extension portion 20 is further divided into a lead region 210 and a lead region 220. A plurality of second wires 211 are disposed on the extension portion 20 relative to the lead region 210, wherein the second wires 211 are parallel to each other and insulated from each other. A plurality of pins 221 electrically insulated from each other are disposed on the extension portion 20 with respect to the pin region 220. The second ends of the second wires 211 are electrically connected to the pins 221, and the second ends of the second wires 211 are electrically connected to the second ends of the corresponding first wires 121.

更具體地說，每一條第二導線211的第一端由引線區域210延伸至引腳區域220並電性連接對應的引腳221。每一條第二導線211的第二端則往觸控感測部10方向延伸並經由周邊區域120的出線口位置30電性連接對應的第一導線121。此外，本實施例中 第二導線211較佳的實施方式可以是藉由第一導線121直接由周邊區域120往引線區域210延伸而形成的，進而可在不增加製程工序的前提下，以同一材料形成觸控感測電路中的第一導線121以及第二導線211。據此，增加線路佈設的精準度，提升成品良率，並降低柔性觸控面板1的製作成本。More specifically, the first end of each of the second wires 211 extends from the lead region 210 to the pin region 220 and is electrically connected to the corresponding pin 221 . The second end of each of the second wires 211 extends toward the touch sensing portion 10 and is electrically connected to the corresponding first wire 121 via the wire exit position 30 of the peripheral region 120. In addition, in this embodiment The preferred embodiment of the second wire 211 can be formed by extending the first wire 121 directly from the peripheral region 120 to the lead region 210, thereby forming touch sensing with the same material without increasing the manufacturing process. a first wire 121 and a second wire 211 in the circuit. Accordingly, the accuracy of the wiring layout is increased, the yield of the finished product is improved, and the manufacturing cost of the flexible touch panel 1 is reduced.

觸控感測部10上周邊區域120的出線口位置30係根據延伸部20突出於觸控感測部10的位置來佈設，且引線區域210的位置相鄰於周邊區域120的出線口位置30。所述第二導線211的數量對應於第一導線121的數量。The outlet position 30 of the upper peripheral region 120 of the touch sensing portion 10 is arranged according to the position of the extending portion 20 protruding from the touch sensing portion 10, and the position of the lead region 210 is adjacent to the outlet of the peripheral region 120. Position 30. The number of the second wires 211 corresponds to the number of the first wires 121.

接著，觸控感測部10的觸控感測區域110與周邊區域120的線路之上另可覆蓋一層保護鏡片，藉以保護觸控感測區域110與周邊區域120的線路。所述保護鏡片層的材料可例如為玻璃材料、塑膠或其他絕緣材料等。Then, the touch sensing area 110 and the peripheral area 120 of the touch sensing unit 10 may be covered with a protective lens to protect the lines of the touch sensing area 110 and the peripheral area 120. The material of the protective lens layer may be, for example, a glass material, a plastic or other insulating material, or the like.

此外，延伸部20的引線區域210內的第二導線211上亦可佈設一層保護層，例如為繞曲性抗氧化絕緣層或是保護膜(Coverlay)。所述繞曲性抗氧化絕緣層可以是於對應引線區域210的延伸部20上方塗上一層透明絕緣油墨、不透明絕緣油墨或是其他等效的絕緣材料。所述透明絕緣油墨或不透明絕緣油墨可依據觸控面板的實際應用用途來對應選用。而延伸部20的引腳區域220上可佈設一層導電碳膠覆蓋於些引腳221之上，用以達到抗氧化以及強化引腳221的作用。In addition, a protective layer may be disposed on the second wire 211 in the lead region 210 of the extending portion 20, for example, a flexible anti-oxidation insulating layer or a coverlay. The flexible anti-oxidation insulating layer may be coated with a transparent insulating ink, an opaque insulating ink or other equivalent insulating material over the extending portion 20 of the corresponding lead region 210. The transparent insulating ink or the opaque insulating ink can be selected according to the practical application of the touch panel. The lead region 220 of the extension portion 20 can be covered with a layer of conductive carbon glue over the pins 221 for anti-oxidation and strengthening the function of the pin 221 .

於此實施例中，該些第一導線121(即主導線)可將感測電極層111的感測信號經由對應的第二導線211(即延伸導線)以及引腳221傳送至後端偵測電路(未繪示)，以進行感測信號的判斷。簡單來說，觸控感測部10上可用於設置習知之觸控感測電路，而延伸部20上則可用於設置習知佈設於可撓式軟性印刷電路板上的後端引線電路。換言之，延伸部20可用於取代習知可撓式軟性印刷電路板於觸控面板結構中的功能，亦即在柔性觸控面板1成形之後 ，柔性基板的延伸部20可***後端控制板上的連接器(未繪示)，以將感測電極層111輸出的感測信號傳送至後端偵測電路，供後端偵測電路判斷確切的觸控位置。In this embodiment, the first conductive lines 121 (ie, the main conductors) can transmit the sensing signals of the sensing electrode layer 111 to the back end detection via the corresponding second conductive lines 211 (ie, extended wires) and the pins 221. A circuit (not shown) for making a determination of the sensing signal. In brief, the touch sensing portion 10 can be used to set a conventional touch sensing circuit, and the extension portion 20 can be used to set a back end lead circuit that is conventionally disposed on a flexible flexible printed circuit board. In other words, the extension portion 20 can be used to replace the function of the conventional flexible flexible printed circuit board in the touch panel structure, that is, after the flexible touch panel 1 is formed. The extension portion 20 of the flexible substrate can be inserted into a connector (not shown) on the back-end control board to transmit the sensing signal outputted by the sensing electrode layer 111 to the back-end detection circuit for the back-end detection circuit to determine. The exact touch location.

據此，柔性觸控面板1可將可撓式軟性印刷電路板的電路與觸控電路整合一體成形，進而於柔性觸控面板1的製造過程中，可不需要經過壓合製程工序，減少至少一道製程工序提升製程良率，同時亦減少壓合的材料成本，例如異向性導電膠、軟性電路板、壓合治具等，降低製作成本。Accordingly, the flexible touch panel 1 can integrally integrate the circuit of the flexible flexible printed circuit board with the touch circuit, thereby reducing the at least one process in the manufacturing process of the flexible touch panel 1 without undergoing a pressing process. The process process improves the process yield and reduces the cost of the material being pressed, such as anisotropic conductive adhesive, flexible circuit board, press fixture, etc., to reduce the manufacturing cost.

值得一提的是，實際實施時，觸控感測區域110內的感測電極層111可以是透過濺鍍一層透明導電膜，例如銦錫氧化物(Indium tin oxide，ITO)、銦鋅氧化物、鋁鋅氧化物、納米銀等納米金屬或納米碳管等，並依據所需的感測電極圖案藉由曝光(exposure)、顯影(develop)、蝕刻(etching)等光刻製程工序形成於柔性基材的觸控感測部10上。周邊區域120內的第一導線121、引線區域210內的第二導線211以及引腳區域220內的引腳221可透過佈設所需的引線佈局圖案之光罩經由光刻、雷射剝離(Laser Ablation)或是印刷(printing)等製作加工工序形成於柔性基材的觸控感測部10及延伸部20上。It is worth mentioning that, in actual implementation, the sensing electrode layer 111 in the touch sensing region 110 may be transparently coated with a transparent conductive film, such as Indium tin oxide (ITO), indium zinc oxide. , aluminum-zinc oxide, nano-silver and other nano-metals or carbon nanotubes, etc., and formed according to the desired sensing electrode pattern by exposure, development, etching, etc. The touch sensing portion 10 of the substrate is placed on the substrate. The first conductive line 121 in the peripheral region 120, the second conductive line 211 in the lead region 210, and the lead 221 in the lead region 220 can be detached by photolithography and laser lithography through a photomask of a desired lead layout pattern (Laser) The manufacturing process such as Ablation or printing is formed on the touch sensing portion 10 and the extending portion 20 of the flexible substrate.

值得一提的是，本實施例中第一導線121、第二導線211以及引腳221較佳地可於同一個製程步驟中形成，以減少製程工序，增加線路佈設的精準度，進而提升成品良率，並降低柔性觸控面板1的製作成本。此外，周邊區域120內的第一導線121佈設於光罩上的位置可依據觸控感測區域110內的感測電極層111的實際佈設位置以及延伸部20的突出位置來配置。本創作領域具有通常知識者應可推知感測電極層111、第一導線121、第二導線211以及引腳221的實際實施方式，故在此不再贅述。It should be noted that, in this embodiment, the first wire 121, the second wire 211, and the pin 221 are preferably formed in the same process step to reduce the process, increase the accuracy of the circuit layout, and thereby improve the finished product. Yield and reduce the manufacturing cost of the flexible touch panel 1. In addition, the position where the first wire 121 in the peripheral region 120 is disposed on the reticle can be configured according to the actual layout position of the sensing electrode layer 111 in the touch sensing region 110 and the protruding position of the extending portion 20 . The actual implementation of the sensing electrode layer 111, the first wire 121, the second wire 211, and the pin 221 should be inferred by those skilled in the art, and therefore will not be described herein.

所述引腳221可以是利用金屬導電材料來實現，且第一導線121與第二導線211是由同一種材料來形成。第一導線121與第二 導線211可以是由透明可繞曲性導電材料，例如銦錫氧化物(Indium tin oxide，ITO)，或是不透明可繞曲性導電材料，例如金、銀、銅或鋁等來實現。由於在導電材料中銀導電性好、阻抗低的優點，故較佳的，第一導線、第二導線及引腳由銀構成，本實施例並不限制。The pin 221 can be realized by a metal conductive material, and the first wire 121 and the second wire 211 are formed of the same material. First wire 121 and second The wire 211 may be realized by a transparent flexible conductive material such as Indium Tin Oxide (ITO) or an opaque flexible conductive material such as gold, silver, copper or aluminum. Since the silver has good conductivity and low impedance in the conductive material, it is preferable that the first wire, the second wire and the lead are made of silver, which is not limited in this embodiment.

再者，於實務上，第一導線121與第二導線211可如上述是一體成形，亦即可為同一條導線，但第一導線121與第二導線211亦可分開製作。在此請注意，第一導線121、第二導線211以及引腳221於同一個製程步驟中形成時，第一導線121、第二導線211以及引腳221選用相同材料。Moreover, in practice, the first wire 121 and the second wire 211 may be integrally formed as described above, that is, the same wire, but the first wire 121 and the second wire 211 may also be separately formed. It should be noted that when the first wire 121, the second wire 211, and the pin 221 are formed in the same process step, the first wire 121, the second wire 211, and the pin 221 are made of the same material.

另外，由於銀具有較好的抗折性、高導電率及低阻抗值等優點，故於一較佳實施方式中，第一導線121與第二導線211可以是以銀來實現。此外，如前述，柔性基材的材料可依據柔性觸控面板1的實際應用用途，例如應用於顯示設備或是應用於觸控鍵盤等來選用透明或不透明之絕緣材料。In addition, in a preferred embodiment, the first conductive line 121 and the second conductive line 211 may be implemented by using silver as a result of the advantages of good bending resistance, high electrical conductivity, and low impedance. In addition, as described above, the material of the flexible substrate may be selected from transparent or opaque insulating materials depending on the practical application of the flexible touch panel 1 , for example, applied to a display device or applied to a touch keyboard or the like.

接著，於一實務上，可於感測電極層111、第一導線121形成的周邊引線線路及第二導線211形成的引線線路外圍另佈設一圈接地線線路，此接地線線路用以消除柔性觸控面板1上的靜電。請參照圖2，圖2繪示本創作第一實施例提供之具靜電消除電路之柔性觸控面板結構示意圖。如圖2所示，可於柔性觸控面板1上佈設一條接地線123，且接地線123的走線穿越周邊區域120以及引線區域210並環繞於該些第一導線121與該些第二導線211之外圍，且接地線123的兩端分別電性連接引腳區域220內另設之接地引腳223，此接地引腳223以於延伸部20***後端控制板上連接器時建立靜電放電路經。值得注意的是，所述接地線123亦可根據實際線路佈局或製程需求，而僅有一端電性連接接地引腳223，本實施例並不限制。所述接地引腳223可以是佈設於該些引腳221的最外側，且與該些引腳221彼此電性絕緣。Then, in a practical process, a grounding line can be disposed on the periphery of the lead line formed by the sensing electrode layer 111, the first lead line 121, and the second lead line 211. The ground line is used to eliminate flexibility. Static electricity on the touch panel 1.

此外，接地線123以及接地引腳223可於製作第一導線121、第二導線211以引腳221的同時形成，進而可不需要增加製程工序。舉例來說，可將接地線123以及接地引腳223的圖案直接設計於第一導線121、第二導線211以引腳221的光罩上或是將接地線123、第一導線121、第二導線211、引腳221以及接地引腳223以印刷方式形成於柔性基材上。如此，接地線123可選用與第一導線121及第二導線211相同的材料來實現。In addition, the grounding wire 123 and the grounding pin 223 can be formed at the same time as the first wire 121 and the second wire 211 are formed by the pin 221, so that the manufacturing process is not required. For example, the pattern of the grounding line 123 and the grounding pin 223 can be directly designed on the first wire 121, the second wire 211 on the reticle of the pin 221 or the grounding wire 123, the first wire 121, and the second.

As such, the ground line 123 can be implemented by the same material as the first wire 121 and the second wire 211.

值得注意的是，於一實務上，所述柔性觸控面板1還可為雙面觸控面板(未繪示)，即柔性觸控面板1可具有一上表面與一下表面。換言之，柔性基材的觸控感測部10與延伸部20分別具有一上表面(未繪示)與一下表面(未繪示)。It should be noted that, in a practical manner, the flexible touch panel 1 can also be a double-sided touch panel (not shown), that is, the flexible touch panel 1 can have an upper surface and a lower surface. In other words, the touch sensing portion 10 and the extending portion 20 of the flexible substrate respectively have an upper surface (not shown) and a lower surface (not shown).

更詳細地說，觸控感測部10上、下表面可分別區分有觸控感測區域110與周邊區域120，而延伸部20上、下表面可對應設置引線區域210與引腳區域220。觸控感測部10上、下表面的觸控感測區域110內可設置感測電極層111，而周邊區域120內則佈設有多條第一導線121電性連接感測電極層111。同樣地，延伸部20上、下表面上的引線區域210對應於觸控感測部10上、下表面上的周邊區域120出線口位置30，且佈設有多條第二導線211電性連接該些第一導線121。延伸部20上、下表面上的引腳區域220內部設有多個引腳221，且該些引腳221分別電性連接該些第二導線211。In more detail, the upper and lower surfaces of the touch sensing portion 10 can respectively distinguish the touch sensing region 110 from the peripheral region 120, and the upper and lower surfaces of the extending portion 20 can be correspondingly disposed with the lead region 210 and the lead region 220. The sensing electrode layer 111 is disposed in the touch sensing region 110 of the upper and lower surfaces of the touch sensing portion 10, and the plurality of first wires 121 are electrically connected to the sensing electrode layer 111 in the peripheral region 120. Similarly, the lead region 210 on the upper and lower surfaces of the extending portion 20 corresponds to the outlet portion 30 of the peripheral region 120 on the upper and lower surfaces of the touch sensing portion 10, and is electrically connected to the plurality of second wires 211. The first wires 121. A plurality of pins 221 are disposed inside the pin regions 220 on the upper and lower surfaces of the extending portion 20, and the pins 221 are electrically connected to the second wires 211, respectively.

舉例來說，觸控感測部10上表面佈設之觸控感測區域110內的感測電極層111可例如為沿第一軸向(例如Y軸)平行排列之感測電極軸，而觸控感測部10下表面佈設之觸控感測區域110內的感測電極層111可例如為沿第二軸向(例如X軸)平行排列之感測電極軸。第一導線121、第二導線211以及引腳221則可分別對應地佈設於觸控感測部10上、下表面以及延伸部20上。附帶一提的是，觸控感測部10上、下表面佈設的感應電極層111的感測電極軸 可重疊並相交，並彼此電性絕緣。For example, the sensing electrode layer 111 in the touch sensing region 110 disposed on the upper surface of the touch sensing portion 10 can be, for example, a sensing electrode axis arranged in parallel along a first axial direction (for example, the Y axis), and can be touched. The sensing electrode layer 111 in the touch sensing region 110 disposed on the lower surface of the sensing portion 10 may be, for example, a sensing electrode axis arranged in parallel along a second axial direction (for example, an X axis).

Incidentally, the sensing electrode axis of the sensing electrode layer 111 disposed on the upper and lower surfaces of the touch sensing portion 10 Can overlap and intersect and be electrically insulated from each other.

另外，感測電極層111亦可配置於柔性觸控面板1的上、下表面，而第一導線121、第二導線211以及引腳221可分別配置於柔性觸控面板1的其中一面，例如下表面。所述第一導線121可如前述電性連接第二導線211，且第二導線211電性連接引腳221。接著，第一導線121可以是透過金屬連通柱電性連接感測電極層111，但本創作並不以此為限。In addition, the sensing electrode layer 111 can also be disposed on the upper and lower surfaces of the flexible touch panel 1 , and the first conductive line 121 , the second conductive line 211 , and the lead 221 can be respectively disposed on one side of the flexible touch panel 1 , for example, for example, lower surface. The first wire 121 can be electrically connected to the second wire 211 as described above, and the second wire 211 is electrically connected to the pin 221 . Then, the first wire 121 may be electrically connected to the sensing electrode layer 111 through the metal connecting post, but the present invention is not limited thereto.

又於再一實務上，所述柔性觸控面板1可是由兩個單面柔性基板貼合所形成的。具體地說，可於第一個柔性基材上的觸控感測部上觸控感測區域內佈設一第一感測電極層，例如為沿第一軸向(例如Y軸)平行排列之感測電極軸，而於第二柔性基材上的觸控感測部上對應觸控感測區域內佈設一第二感測電極層，例如為沿第二軸向(例如X軸)平行排列之感測電極軸。In yet another practice, the flexible touch panel 1 can be formed by bonding two single-sided flexible substrates. Specifically, a first sensing electrode layer may be disposed in the touch sensing area on the touch sensing portion of the first flexible substrate, for example, arranged in parallel along the first axis (eg, the Y axis). Sensing the electrode shaft, and a second sensing electrode layer is disposed in the touch sensing region on the touch sensing portion of the second flexible substrate, for example, arranged in parallel along the second axis (eg, the X axis) The sensing electrode shaft.

接著，於第一柔性基材上觸控感測部對應的周邊區域形成多條的第一導線電性連接第一柔性基材上觸控感測區域內的第一感測電極層，而於第二柔性基材上觸控感測部對應的周邊區域形成多條的第一導線電性連接第二柔性基材上觸控感測區域內的第二感測電極層。此外，可分別於對應於第一柔性基材的延伸部以及第二柔性基材的延伸部上的引線區域與引腳區域分別形成對應第一導線之第二導線及引腳。And forming a plurality of first wires electrically connected to the first sensing electrode layer in the touch sensing region on the first flexible substrate on the peripheral region corresponding to the touch sensing portion on the first flexible substrate, and The peripheral region corresponding to the touch sensing portion of the second flexible substrate forms a plurality of first wires electrically connected to the second sensing electrode layer in the touch sensing region on the second flexible substrate. In addition, a second wire and a pin corresponding to the first wire may be respectively formed on the extension portion corresponding to the first flexible substrate and the lead portion and the lead region on the extension portion of the second flexible substrate.

總而言之，柔性觸控面板1的實現方式可依據實際製程或產品設計需求來決定，本創作並不以此為限。要說明的是，柔性觸控面板1的實際結構與實體形狀可依據實際應用方式來調整。同樣地，第一導線121、第二導線211以及引腳221的實際數量亦是依據實際感測電極層111需求來設置。第一導線121的走線方式也會依據實際感測電極層111的結構及柔性觸控面板1的大小來調整。另外，本創作亦不限定感測電極層111、第一導線121、第二導線211、接地線123以及引腳221實際實施方式、種類及實體架 構。換言之，圖1與圖2僅用以作為說明柔性觸控面板1的一種示範實施方式之示意圖，並非用以限定本創作。In summary, the implementation of the flexible touch panel 1 can be determined according to the actual process or product design requirements, and the creation is not limited thereto. It should be noted that the actual structure and the physical shape of the flexible touch panel 1 can be adjusted according to the actual application manner. Similarly, the actual number of the first wire 121, the second wire 211, and the pin 221 is also set according to the actual sensing electrode layer 111 requirement. The routing manner of the first wire 121 is also adjusted according to the structure of the actual sensing electrode layer 111 and the size of the flexible touch panel 1. In addition, the present invention also does not limit the actual implementation, type, and physical frame of the sensing electrode layer 111, the first wire 121, the second wire 211, the ground line 123, and the pin 221 Structure. In other words, FIG. 1 and FIG. 2 are only used as a schematic diagram for explaining an exemplary embodiment of the flexible touch panel 1, and are not intended to limit the present creation.

於另一實施方式中，第一實施例所述之柔性基材可具有多個延伸部20，該些延伸部20分別突出於觸控感測部10的任一側，延伸部20數量對應周邊區域120的數量，更進一步地說明，周邊區域120的佈設位置與數量可依據延伸部20突出於觸控感測部10的位置與數量來對應配置。In another embodiment, the flexible substrate of the first embodiment may have a plurality of extending portions 20 respectively protruding from either side of the touch sensing portion 10, and the number of the extending portions 20 corresponding to the periphery The number of regions 120 is further illustrated. The arrangement position and number of the peripheral regions 120 may be correspondingly configured according to the position and number of the extension portions 20 protruding from the touch sensing portion 10.

請參考圖3，圖3繪示本創作第二實施例提供之柔性觸控面板結構的示意圖。柔性觸控面板2為單面觸控面板。圖3與圖1的不同處在於，於柔性觸控面板2的結構中，柔性基材包括觸控感測部10、第一延伸部20a及第二延伸部20b。第一延伸部20a及第二延伸部20b分別沿第一軸向(如Y軸)相對應突出於觸控感測部10，例如第一延伸部20a突出於觸控感測部10的上側(例如第一側)，而第二延伸部20b突出於觸控感測部10的下側(例如相對於第一側之第二側)。Please refer to FIG. 3 , which illustrates a schematic diagram of a flexible touch panel structure provided by the second embodiment of the present invention. The flexible touch panel 2 is a single-sided touch panel. The difference between FIG. 3 and FIG. 1 is that, in the structure of the flexible touch panel 2, the flexible substrate includes the touch sensing portion 10, the first extending portion 20a, and the second extending portion 20b. The first extending portion 20a and the second extending portion 20b respectively protrude from the touch sensing portion 10 along the first axial direction (such as the Y axis). For example, the first extending portion 20a protrudes from the upper side of the touch sensing portion 10 ( For example, the first side), and the second extending portion 20b protrudes from the lower side of the touch sensing portion 10 (for example, with respect to the second side of the first side).

更進一步地說，觸控感測部10上區分有觸控感測區域110以及第一周邊區域120a及第二周邊區域120b。第一延伸部20a以及第二延伸部20b上皆區分有引線區域210以及引腳區域220。更詳細地說，所述引線區域210以及引腳區域220分別佈設於第一延伸部20a及第二延伸部20b相對於觸控感測部10上設有觸控感測區域110以及第一周邊區域120a及第二周邊區域120b的該面上。換句話說，觸控感測區域110、第一周邊區域120a、第二周邊區域120b、第一延伸部20a以及第二延伸部20b上的引線區域210以及引腳區域220皆設於柔性基材的同一面上。觸控感測區域110如前述實施例佈設感測電極層111，其中感測電極層111亦可如前述是由多條相互平行且彼此絕緣之感測電極軸所形成。第一周邊區域120a設置於觸控感測區域110的上側，且第一周邊區域120a 的出線口位置30a對應於第一延伸部20a突出於觸控感測部10的位置。第二周邊區域120b設置於觸控感測區域110的下側，且第二周邊區域120b的出線口位置30b對應於第二延伸部20b突出於觸控感測部10的位置。第一延伸部20a及第二延伸部20b的架構與上述實施例延伸部20相同，故不再贅述。Furthermore, the touch sensing unit 10 has a touch sensing area 110 and a first peripheral area 120a and a second peripheral area 120b. The lead extension region 210 and the lead region 220 are distinguished by the first extension portion 20a and the second extension portion 20b. In more detail, the lead region 210 and the lead region 220 are respectively disposed on the first extending portion 20a and the second extending portion 20b, and the touch sensing region 110 and the first periphery are disposed on the touch sensing portion 10. The face of the region 120a and the second peripheral region 120b. In other words, the touch sensing region 110, the first peripheral region 120a, the second peripheral region 120b, the first extending portion 20a, and the lead region 210 on the second extending portion 20b and the lead region 220 are all disposed on the flexible substrate. On the same side. The touch sensing region 110 is provided with the sensing electrode layer 111 as in the foregoing embodiment, wherein the sensing electrode layer 111 may also be formed by a plurality of sensing electrode axes that are parallel to each other and insulated from each other as described above. The first peripheral area 120a is disposed on an upper side of the touch sensing area 110, and the first peripheral area 120a The outlet position 30a corresponds to a position at which the first extension portion 20a protrudes from the touch sensing portion 10. The second peripheral area 120 b is disposed on the lower side of the touch sensing area 110 , and the outlet position 30 b of the second peripheral area 120 b corresponds to the position where the second extending portion 20 b protrudes from the touch sensing portion 10 . The structures of the first extension portion 20a and the second extension portion 20b are the same as those of the extension portion 20 of the above embodiment, and therefore will not be described again.

第一周邊區域120a內設有多條第一導線121a及第二周邊區域120b內設有多條第一導線121b。第一周邊區域120a內及第二周邊區域120b內的第一導線121a及121b分別電性連接觸控感測區域110的感測電極層111。第一周邊區域120a內的多條第一導線121a另電性連接第一延伸部20a上引線區域210內的第二導線211。第二周邊區域120b內的多條第一導線121b另電性連接第二延伸部20b上引線區域210內的第二導線211。A plurality of first wires 121a and a plurality of first wires 121b are disposed in the first peripheral region 120a. The first wires 121a and 121b in the first peripheral region 120a and the second peripheral region 120b are electrically connected to the sensing electrode layer 111 of the touch sensing region 110, respectively. The plurality of first wires 121a in the first peripheral portion 120a are electrically connected to the second wires 211 in the lead regions 210 on the first extending portion 20a. The plurality of first wires 121b in the second peripheral region 120b are electrically connected to the second wires 211 in the lead regions 210 on the second extending portion 20b.

於一實施方式，第一周邊區域120a的第一導線121a的一端可由上向下延伸連接觸控感測區域110內的感測電極層111，而第二周邊區域120b的第一導線121b的一端則可由下向上延伸連接觸控感測區域110內感測電極層111。從而，第一周邊區域120a與第二周邊區域120b內的該些第一導線121a及121b可分別將感測電極層111的該些感測電極軸的感測信號引出並經由第一延伸部20a、第二延伸部20b上引線區域210內的該些第二導線211與引腳區域220的該些引腳221傳送至後端偵測電路判斷確切的觸控位置。值得一提的是，將觸控感測區域110內感測電極層111的感測電極軸之感測信號由上下兩側同時引出，可讓後端偵測電路相互比對，進而增加感測信號的可信度，加強偵測效能。In one embodiment, one end of the first wire 121a of the first peripheral region 120a may extend from the top to the bottom to connect the sensing electrode layer 111 in the touch sensing region 110, and one end of the first wire 121b of the second peripheral region 120b. The sensing electrode layer 111 in the touch sensing area 110 can be connected from the bottom to the top. Therefore, the first conductive lines 121a and 121b in the first peripheral area 120a and the second peripheral area 120b can respectively extract the sensing signals of the sensing electrode axes of the sensing electrode layer 111 and pass through the first extending portion 20a. The second wires 211 in the lead region 210 of the second extension portion 20b and the pins 221 of the pin region 220 are transmitted to the back end detecting circuit to determine the exact touch position. It is worth mentioning that the sensing signals of the sensing electrode axes of the sensing electrode layer 111 in the touch sensing area 110 are simultaneously extracted from the upper and lower sides, so that the back-end detecting circuits can be compared with each other, thereby increasing the sensing. The reliability of the signal enhances detection performance.

於另一實施方式，第一周邊引線區域120a的第一導線121a可由上向下延伸連接觸控感測區域110內沿第一軸向(如Y軸)佈設之感測電極軸，而第二周邊引線區域120b的第一導線121b則由下向上延伸連接沿第二軸向(如X軸)佈設之感測電極軸。第一周邊引線區域120a與第二周邊引線區域120b內的該些第一導線 121a及121b可將該些沿第一軸向與第二軸向佈設之感測電極軸的感測信號分別引出並傳送至後端偵測電路判斷確切的觸控位置。In another embodiment, the first conductive line 121a of the first peripheral lead region 120a may extend from the top to the bottom to connect the sensing electrode axis disposed along the first axial direction (such as the Y axis) in the touch sensing region 110, and the second The first wire 121b of the peripheral lead region 120b extends from the bottom to the top to connect the sensing electrode axis disposed along the second axial direction (such as the X axis). The first peripheral lead region 120a and the first lead wires in the second peripheral lead region 120b The sensing signals of the sensing electrode axes disposed along the first axial direction and the second axial direction are respectively taken out and transmitted to the back end detecting circuit to determine the exact touch position.

藉此可降低觸控感測部10上第一周邊區域120a與第二周邊區域120b內所需佈設該些第一導線121a及121b的數量與佈線密度。同時，第一、第二延伸部20a、20b上引線區域210內的第二導線211與引腳區域220內的引腳221所需的數量與佈線密度也相對地降低。如此，第一延伸部20a與第二延伸部20b的尺寸也可縮小。Thereby, the number and wiring density of the first wires 121a and 121b to be disposed in the first peripheral region 120a and the second peripheral region 120b of the touch sensing portion 10 can be reduced. At the same time, the number of required wires and the wiring density of the second wires 211 in the lead regions 210 on the first and second extension portions 20a, 20b and the lead regions 220 are also relatively lowered. As such, the dimensions of the first extension portion 20a and the second extension portion 20b can also be reduced.

於再一實施方式，第一周邊區域120a的第一導線121a可由上向下延伸連接觸控感測區域110內上半部感測電極層111上所設之感測電極軸(例如虛線以上之感測電極軸)。第二周邊區域120b的第一導線121b則由下向上延伸連接沿觸控感測區域110內下半部感測電極層111上所設之感測電極軸(例如虛線以下之感測電極軸)。藉此，除可降低觸控感測部10上第一周邊區域120a與第二周邊區域120b內所需佈設該些第一導線121a及121b以及第一、第二延伸部20a、20b上引線區域210內的第二導線211與引腳區域內220的引腳221的數量與佈線密度之外，還可縮短第一周邊區域120a與第二周邊區域120b內第一導線121a及121b的走線長度，減少佈設第一導線121a及121b的所需材料，降低觸控面板的製作成本。In still another embodiment, the first conductive line 121a of the first peripheral region 120a may extend from the top to the bottom to connect the sensing electrode axis disposed on the upper sensing electrode layer 111 in the touch sensing region 110 (eg, above the dotted line) Sensing electrode axis). The first wire 121b of the second peripheral region 120b extends from the bottom to the top along the sensing electrode axis disposed on the sensing electrode layer 111 in the lower half of the touch sensing region 110 (for example, the sensing electrode axis below the broken line) . Therefore, in addition, the first lead wires 121a and 121b and the lead regions on the first and second extending portions 20a and 20b are disposed in the first peripheral region 120a and the second peripheral region 120b of the touch sensing portion 10. In addition to the number of the second wires 211 in the 210 and the pins 221 in the pin region 220 and the wiring density, the lengths of the traces of the first wires 121a and 121b in the first peripheral region 120a and the second peripheral region 120b may also be shortened.

The pins are electrically connected to the second wires. Wherein, the pins can be formed on the extension of the flexible substrate by using different photomasks by photolithography, laser stripping or printing.

附帶一提的是，上述步驟S150、S160、S170順序是可彼此調換。換言之，保護鏡片可依據實際製程需求於柔性基板上所有工序完成或者延伸部上引線區域內的第二導線之上佈設繞曲性抗氧化絕緣層工序完成之後，再將保護鏡片以貼合方式覆蓋觸控感測部上方。同樣地，步驟S160所述的在延伸部相對應於引線區域內的上方覆設繞曲性抗氧化絕緣層或保護膜與步驟S170所述的在延伸部上於引腳區域內覆設一層導電碳膠，亦可依據實際製程需求相互調換，本實施例並不限制。Incidentally, the above steps S150, S160, and S170 are sequentially interchangeable.

The grounding wire and the grounding pin and the like are used to eliminate static electricity on the flexible touch panel.

另外，接地線可與第一導線、第二導線、引腳以及接地引腳同時形成於柔性基材上，進而可不需要增加製程工序。當接地線與第一導線以及第二導線同時形成於柔性基材上，可選用與第一導線及第二導線相同的材料來實現。但接地線亦可依據實際製程需求，與第一導線以及第二導線分開製成，例如在第一導線及第二 導線形成之後，再透過印刷方式將接地線以及接地引腳形成於柔性基材上。或是於製作第一導線、第二導線、引腳及接地引腳之後再形成接地線於柔性基材上，本實施例並不限制。In addition, the grounding wire can be formed on the flexible substrate simultaneously with the first wire, the second wire, the pin, and the grounding pin, thereby eliminating the need for an additional process. When the grounding wire is formed on the flexible substrate simultaneously with the first wire and the second wire, the same material as the first wire and the second wire may be selected. However, the grounding wire can also be made separately from the first wire and the second wire according to actual process requirements, for example, in the first wire and the second wire. After the wire is formed, the ground wire and the ground pin are formed on the flexible substrate by printing. The ground wire is formed on the flexible substrate after the first wire, the second wire, the pin and the ground pin are formed, and the embodiment is not limited.
