Description
本創作有關於一種觸控技術，且特別是一種觸控面板。This creation relates to a touch technology, and in particular to a touch panel.
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裝置中，例如手機、手提電腦以及掌上型電腦等。觸控面板(touch panel)一般會與顯示面板(display panel)相整合為觸控顯示螢幕，以作為電子裝置的輸入輸出介面，達到觸控顯示功能。據此，使用者可透過手指或觸控物件(如觸控筆)觸碰觸控顯示螢幕來控制電子裝置，以對應操控電子裝置。In recent years, with the development of touch panel technology, touch panels have been widely used in various electronic devices, such as mobile phones, laptop computers, and palmtop computers. The touch panel is generally integrated with the display panel as a touch display screen to serve as an input/output interface of the electronic device to achieve a touch display function. Accordingly, the user can touch the touch display screen through a finger or a touch object (such as a stylus) to control the electronic device to correspondingly operate the electronic device.
現行觸控面板的觸控感應電路，一般是製作於導電薄膜或是單片導電玻璃(One ITO Glass)上。具體地說，觸控感應電路的多個感測電極的觸控陣列通常佈設於導電薄膜或是單片導電玻璃的可視區域，而周邊引線則是佈設於導電薄膜或是單片導電玻璃的周邊區域。習知導電薄膜係利用異向性導電膠(Anisotropic conductive film，ACF)透過熱壓合方式與可撓式軟性印刷電路板(Flexible Print Circuit Board，FPC)相黏合。藉此，透過設於導電薄膜上連接觸控陣列的周邊引線電路來與軟性印刷電路板上相對應的引線電路相連，以將感測信號傳至後端偵測判斷電路。The touch sensing circuit of the current touch panel is generally fabricated on a conductive film or a single piece of conductive glass (One ITO Glass). Specifically, the touch array of the plurality of sensing electrodes of the touch sensing circuit is usually disposed on the conductive film or the visible area of the single conductive glass, and the peripheral leads are disposed on the periphery of the conductive film or the single conductive glass. region. Conventional conductive films are bonded to a flexible printed circuit board (FPC) by means of an anisotropic conductive film (ACF) through a thermocompression bonding method. Thereby, the peripheral lead circuit connected to the touch array disposed on the conductive film is connected to the corresponding lead circuit on the flexible printed circuit board to transmit the sensing signal to the back end detection judging circuit.
然而，導電薄膜通常是使用聚對苯二甲酸乙二醇酯薄膜(PET Film)的材料，所能承受的溫度較低，故而在導電薄膜與可撓式軟性印刷電路板的貼合過程中，容易因壓合產生應力而使導電薄膜引起變形，導致水波紋問題。具體地說，在導電薄膜之周邊區域上佈設間距過大的銀線線路，導電薄膜會於貼合過程中因引線區 域與非引線區域的貼合膠固化收縮率不同形成應力，而在高溫下牽拉上下層的導電薄膜引起其表面不平整。據此，當外部投射的可見光通過導電薄膜時，會因導電薄膜表面不平整而產生不同的干涉現象，進而會在可視區域與周邊區域之間形成一串凹凸不平的水波紋，造成視覺上的差異。再者，隨著可視區域的擴大，使引線線路與可視區域之間的距離越來越近，水波紋的現象就會越明顯，降低了觸控面板的良率。However, the conductive film is usually a material using a polyethylene terephthalate film (PET film), which can withstand a relatively low temperature, so that in the process of bonding the conductive film to the flexible flexible printed circuit board, It is easy to cause deformation of the conductive film due to stress generated by press-bonding, resulting in water ripple problems. Specifically, a silver wire line having an excessively large pitch is disposed on a peripheral region of the conductive film, and the conductive film is exposed to the lead region during the bonding process. The curing shrinkage of the adhesive of the domain and the non-lead region is different to form a stress, and the conductive film of the upper and lower layers is pulled at a high temperature to cause the surface to be uneven. Accordingly, when the externally projected visible light passes through the conductive film, different interference phenomena are generated due to the uneven surface of the conductive film, and a series of rugged water ripples are formed between the visible area and the peripheral area, thereby causing visual appearance. difference. Moreover, as the visible area is enlarged, the distance between the lead line and the visible area is getting closer and closer, and the phenomenon of water ripple is more obvious, which reduces the yield of the touch panel.
有鑑於此，本創作實施例提供一種觸控面板，此觸控面板可透過於觸控面板上非可視區內佈設多條延伸導線，來使每條引線間的間距縮短，以均勻地撐起導電薄膜，避免發生因導電薄膜表面不平整，產生不同干涉現象，而於可視區域與周邊區域之間形成水波紋，影響顯示品質。In view of the above, the present invention provides a touch panel capable of arranging a plurality of extension wires in a non-visible area on the touch panel to shorten the spacing between each lead to evenly support The conductive film avoids the occurrence of different interference phenomena due to the unevenness of the surface of the conductive film, and forms a water ripple between the visible area and the surrounding area, which affects the display quality.

任兩相鄰的延伸導線177之間的間距W是小於位於這兩條延伸導線177下方的兩個第二端子部175之間的間距。於實務上，任兩相鄰的延伸導線177之間的間距W小於1.4毫米(mm)，較佳係介於0.2毫米至1.4毫米之間。每一條引線17的延伸導線177沿基板11的第一軸向DE1方向的長度L於本實施例是大於兩相鄰的延伸導線177之間的間距W。The spacing W between any two adjacent extension wires 177 is smaller than the spacing between the two second terminal portions 175 located below the two extension wires 177. In practice, the spacing W between any two adjacent extension wires 177 is less than 1.4 millimeters (mm), preferably between 0.2 millimeters and 1.4 millimeters. The length L of the extended wire 177 of each of the leads 17 in the first axial direction DE1 of the substrate 11 is greater than the spacing W between the two adjacent extended wires 177 in this embodiment.
於一實施方式中，當兩相鄰之延伸導線177之間的間距介於0.2毫米至1.4毫米之間時，各延伸導線177沿第一軸向DE1方向的長度L係介於1.8倍的間距W至29倍的間距W之間。換言之，當兩相鄰之延伸導線177之間的間距W介於0.2毫米至1.4毫米之間時，各延伸導線177沿第一軸向DE1方向的長度L與兩相鄰之延伸導線177之間的間距W的比值是介於1.8~29之間。In one embodiment, when the distance between two adjacent extended wires 177 is between 0.2 mm and 1.4 mm, the length L of each of the extended wires 177 along the first axial direction DE1 is 1.8 times the pitch. W to 29 times the spacing between W. In other words, when the spacing W between two adjacent extending wires 177 is between 0.2 mm and 1.4 mm, the length L of each of the extending wires 177 along the first axial direction DE1 and between the two adjacent extending wires 177 The ratio of the pitch W is between 1.8 and 29.
而於另一實施方式中，當兩相鄰之延伸導線177之間的間距W介於0.2毫米至0.4毫米之間時，各延伸導線177沿第一軸向DE1方向的長度L係介於9倍的間距W至29倍的間距W之間。換言之，當兩相鄰之延伸導線177之間的間距W介於0.2毫米至0.4毫米之間時，各延伸導線177沿第一軸向DE1方向的長度L與兩相鄰之延伸導線177之間的間距W的比值係介於9~29之間。In another embodiment, when the spacing W between two adjacent extending wires 177 is between 0.2 mm and 0.4 mm, the length L of each of the extending wires 177 along the first axis in the DE1 direction is between 9. The spacing is between W and 29 times the spacing W. In other words, when the spacing W between two adjacent extending wires 177 is between 0.2 mm and 0.4 mm, the length L of each of the extending wires 177 along the first axial direction DE1 and between the two adjacent extending wires 177 The ratio of the spacing W is between 9 and 29.
所述延伸導線177沿第一軸向DE1方向的長度L亦可以是依據相鄰之第一端子部171之間的間距(例如距離d1)來設置，其中第一端子部171是用以連接後端偵測電路的連接接墊。每條引線17與可視區域13之間的距離為d2。所述距離d2可依據所需可視區域13的面積大小與引線17的佈設面積需求來調整。於本實施 例中，所述距離d2較佳係介於0.2毫米與0.4毫米之間。The length L of the extension wire 177 along the first axial direction DE1 may also be set according to the spacing (for example, the distance d1) between the adjacent first terminal portions 171, wherein the first terminal portion 171 is used for connection. The connection pad of the terminal detection circuit. The distance between each lead 17 and the visible area 13 is d2. The distance d2 can be adjusted according to the size of the area of the desired visible area 13 and the layout area requirement of the lead wires 17. In this implementation In the example, the distance d2 is preferably between 0.2 mm and 0.4 mm.
值得注意的是，習知因相鄰引線17靠近可視區域的一端之間的間距過大，而使得設有觸控陣列及多條引線17的基板11於壓合過程中因引線區域與非引線區域的黏合膠固化收縮率不同，引起基板11表面不平整。當外部投射的可見光通過基板11時，會因導電薄膜表面不平整而產生不同的干涉現象，進而會在可視區域13與周邊區域15之間形成一串凹凸不平的水波紋，造成視覺上的差異。故由可視區域的擴增而縮短引線17與可視區域13之間的距離d2，例如距離d2小於0.4毫米時，可視區域與周邊區域之間的水波紋的現象即會越來越明顯，影響顯示品質。It should be noted that the spacing between the ends of the adjacent lead wires 17 near the visible region is too large, so that the substrate 11 provided with the touch array and the plurality of leads 17 is subjected to the lead region and the non-lead region during the pressing process. The adhesive has different curing shrinkage rates, causing the surface of the substrate 11 to be uneven. When the externally projected visible light passes through the substrate 11, different interference phenomena may occur due to the uneven surface of the conductive film, and a series of rugged water ripples may be formed between the visible region 13 and the peripheral region 15 to cause a visual difference. . Therefore, the distance d2 between the lead 17 and the visible area 13 is shortened by the expansion of the visible area. For example, when the distance d2 is less than 0.4 mm, the phenomenon of water ripple between the visible area and the surrounding area becomes more and more obvious, affecting the display. quality.
據此，本實施例藉由增設延伸導線177以均勻地支撐設有觸控陣列及多條引線的基板11，有效避免基板11於壓合過程中因引線區域與非引線區域的黏合膠固化收縮不同而引起透明導電膜表面不平整。當外部投射的可見光通過基板11時，會因導電薄膜表面不平整而產生不同的干涉現象，進而形成水波紋。從而，即便可視區域13的面積擴增，使引線17鄰近於可視區域13一端與可視區域之間的距離小於0.4毫米，也不會有水波紋現象產生。據此，本創作可解決透明基板11於壓合中因膠合固化收縮不同而造成表面不平整，導致因光線干涉不同產生水波紋的問題，且在可視區域13的面積擴增下，仍得以維持可視區域13的顯示品質。Accordingly, in this embodiment, the extension lead 177 is added to uniformly support the substrate 11 provided with the touch array and the plurality of leads, thereby effectively preventing the substrate 11 from curing and shrinking due to the bonding of the lead region and the non-lead region during the pressing process. The surface of the transparent conductive film is not flat due to the difference. When the externally projected visible light passes through the substrate 11, different interference phenomena may occur due to uneven surface of the conductive film, thereby forming water ripples. Thus, even if the area of the visible area 13 is enlarged, the distance between the end of the lead 17 adjacent to the visible area 13 and the visible area is less than 0.4 mm, and no water ripple phenomenon occurs. Accordingly, the present invention can solve the problem that the transparent substrate 11 is uneven due to different curing and shrinkage in the press-bonding, resulting in water ripple due to different light interference, and is maintained under the area expansion of the visible region 13. The display quality of the visible area 13.
附帶一提的是，如圖2所示，本實施例之揭示的延伸導線177為單一條條狀導線。然而，在實務上，每一條延伸導線177可包括多條沿基板11的第一軸向DE1方向呈一直線排列之線段。該些延伸導線177可佈設於相對應的該第二端子部175的上方，且該些延伸導線177的至少其中一部份與第二端子部175重疊。該與第二端子部175重疊之延伸導線177並與第二端子部175電性連接該些延伸導線177之間的間距係介於0.2毫米至1.4毫米之間。Incidentally, as shown in FIG. 2, the extended wire 177 disclosed in the embodiment is a single strip wire. However, in practice, each of the extension wires 177 may include a plurality of line segments arranged in a line along the first axial direction DE1 of the substrate 11. The extension wires 177 can be disposed above the corresponding second terminal portions 175, and at least a portion of the extension wires 177 overlap the second terminal portions 175. The distance between the extension wire 177 overlapping the second terminal portion 175 and the second terminal portion 175 electrically connecting the extension wires 177 is between 0.2 mm and 1.4 mm.
特別說明的是，只要使延伸導線177沿基板11的第一軸向 DE1方向的總長度大於第二端子部175沿第一軸向DE1方向的長度，並縮短相鄰引線17鄰近於可視區域13一端之間的間距即可達到透過延伸導線175均勻地撐起佈設有引線17的基板11的目的。此外，延伸導線177的形狀亦可依據實際設計需求為矩形狀或其他幾何形狀，只要使延伸導線177的寬度(即延伸導線177沿基板11的第一軸向DE1方向的長度)大於或等於觸控陣列中該些感測電極軸131的寬度(即感測電極軸131沿基板11的第一軸向DE1方向的長度)即可。In particular, as long as the extension wire 177 is along the first axis of the substrate 11 The total length of the direction of the DE1 is greater than the length of the second terminal portion 175 in the direction of the first axial direction DE1, and the spacing between the adjacent leads 17 adjacent to the end of the visible region 13 is shortened to be evenly supported by the extension wire 175. The purpose of the substrate 11 of the lead 17 is. In addition, the shape of the extension wire 177 may also be rectangular or other geometric shape according to actual design requirements, as long as the width of the extension wire 177 (ie, the length of the extension wire 177 along the first axial direction DE1 of the substrate 11) is greater than or equal to the touch. The width of the sensing electrode shaft 131 in the array (ie, the length of the sensing electrode shaft 131 along the first axial direction DE1 of the substrate 11) may be used.
如前述，引線17的第一端子部171、導線部173及第二端子部175與延伸導線177在製程上是分開形成於基板11上。舉例來說，每條引線17的第一端子部171、導線部173以及第二端子部175可以是以同一道工序先形成於基板11上周邊區域15內，其中所述工序可以是印刷製程工序。而後，於每條引線17的第二端子部175的上方以另一道印刷製程工序形成延伸導線177。As described above, the first terminal portion 171, the lead portion 173, and the second terminal portion 175 of the lead 17 are formed separately from the extension lead 177 on the substrate 11 in the process. For example, the first terminal portion 171, the lead portion 173, and the second terminal portion 175 of each lead 17 may be formed in the upper peripheral region 15 of the substrate 11 in the same process, wherein the process may be a printing process . Then, an extension wire 177 is formed over the second terminal portion 175 of each lead 17 by another printing process.

於一實務上，當兩相鄰之延伸導線177之間的間距W介於0.2毫米至1.4毫米之間時，各延伸導線177沿基板11的第一軸向DE1方向的長度L介於1.8倍間距W~29倍間距W。換言之，當兩相鄰之延伸導線177之間的間距W介於0.2毫米至1.4毫米之間時，各延伸導線177沿基板11的第一軸向DE1方向的長度L與兩相鄰之延伸導線177之間的間距W的比值是介於1.8~29之間。而於另一實務上，當兩相鄰之延伸導線177之間的間距W介於0.2 毫米至0.4毫米之間時，各延伸導線177沿基板11的第一軸向DE1方向的長度L係介於9倍間距W至29倍間距W之間。換言之，當兩相鄰之延伸導線177之間的間距W介於0.2毫米至0.4毫米之間時，各延伸導線177的長度L與兩相鄰之延伸導線177之間的間距W與比值介於9~29之間。In a practical matter, when the spacing W between two adjacent extending wires 177 is between 0.2 mm and 1.4 mm, the length L of each of the extending wires 177 along the first axial direction DE1 of the substrate 11 is 1.8 times. The spacing is W~29 times the spacing W. In other words, when the spacing W between two adjacent extending wires 177 is between 0.2 mm and 1.4 mm, the length L of each of the extending wires 177 along the first axial direction DE1 of the substrate 11 and the two adjacent extending wires The ratio of the spacing W between 177 is between 1.8 and 29. In another practice, when the spacing between two adjacent extension wires 177 is between 0.2 The length L of each of the extension wires 177 in the first axial direction DE1 of the substrate 11 is between 9 and 9 times the pitch W between the millimeters and 0.4 mm. In other words, when the spacing W between two adjacent extending wires 177 is between 0.2 mm and 0.4 mm, the length W of each of the extending wires 177 and the spacing W between the two adjacent extending wires 177 are proportional to each other. Between 9~29.
另外，引線17的第一端子部171、導線部173、第二端子部175以及延伸導線177亦可以是以同一層金屬層來實現。換言之，第一端子部171、導線部173、第二端子部175以及延伸導線177可以是一體成形，例如同時藉由印刷製作方式形成於基板11上。Further, the first terminal portion 171 of the lead wire 17, the lead portion 173, the second terminal portion 175, and the extension wire 177 may be realized by the same metal layer. In other words, the first terminal portion 171, the lead portion 173, the second terminal portion 175, and the extension lead 177 may be integrally formed, for example, simultaneously formed on the substrate 11 by printing.
上述每一條延伸導線177亦可以是由多條條狀線段沿基板11的第一軸向DE1方向以一直線方式排列。該些條延伸導線177的至少其中一與第二端子部175重疊，並電性連接第二端子部175，但本實施例並不限制。要說明得是，圖5僅為用以說明觸控面板的一種製作方法，並非用以限定本創作。Each of the extension wires 177 may be arranged in a line in a line along the first axial direction DE1 of the substrate 11 by a plurality of strip segments. At least one of the plurality of extension wires 177 overlaps with the second terminal portion 175 and is electrically connected to the second terminal portion 175, but the embodiment is not limited. It should be noted that FIG. 5 is only a method for explaining the touch panel, and is not intended to limit the creation.
綜上所述，本創作實施例所提供的觸控面板與其製造方法，此觸控面板與其製造方法可透過增加觸控面板中具觸控陣列的基板上周邊引線鄰近可視區域一端的導線長度，以縮短該些周邊引線於鄰近可視區域一端之間的間距。據此，以均勻地撐起基板，使基板的表面於壓合過程中不會因連接引線區域與非引線區域的收縮不同產生變形，有效避免於可視區邊緣發生水波紋現象，提高顯示品質。In summary, the touch panel and the manufacturing method thereof are provided by adding the length of the wire adjacent to the visible end of the peripheral lead of the substrate with the touch array in the touch panel. To shorten the spacing between the peripheral leads at one end of the adjacent visible area. Accordingly, the substrate is uniformly supported so that the surface of the substrate is not deformed by the shrinkage of the connecting lead region and the non-lead region during the pressing process, thereby effectively preventing water ripple at the edge of the visible region and improving display quality.
