Description
本創作是有關於一種觸控技術，且特別是有關於一種觸控面板。This creation is related to a touch technology, and in particular to a touch panel.
近年來，手機、車用導航系統、可攜式電腦、電腦等具有觸控輸入功能的電子設備已被廣泛使用，而這些產品通常配有觸控面板。現技術中的觸控面板可以為電阻式、電容式、紅外線感應式、電磁感應式、音波感應式等等。In recent years, electronic devices with touch input functions, such as mobile phones, car navigation systems, portable computers, and computers, have been widely used, and these products are usually equipped with a touch panel. The touch panel in the prior art can be resistive, capacitive, infrared inductive, electromagnetic inductive, sonic inductive, and the like.
舉例而言，電容式觸控面板可被定義有一觸控區和位於該觸控區至少一側的周邊區，觸控區內包括至少一軸向導電件，每一導電件可透過周邊區的連接墊分別與一軟性印刷電路板的接合墊耦合，進而將導電件電性連接至軟性電路板，以外接系統的控制電路。當導電件僅一端連接到控制電路時，信號則可能因導電件電阻損耗，從連接控制電路的這一端逐步衰減至另一端；為減小信號衰減，通常會將導電件兩端分別電性連接到兩個連接墊，而這兩個連接墊又分別連接到軟性電路板的兩個接合墊上，但這種情況下軟性電路板的接合墊數量以及軟性電路板的面積就大大增加，而周邊區的連接墊和軟性電路板的設置位置，就可能干涉到同樣位於周邊區的觸控面板商標區域或按鍵、通孔區域，而影響觸控面板的組裝。For example, the capacitive touch panel can be defined with a touch area and a peripheral area on at least one side of the touch area. The touch area includes at least one axial conductive member, and each conductive member can pass through the peripheral area.

To two connection pads, which are respectively connected to the two bonding pads of the flexible circuit board, but in this case, the number of bonding pads of the flexible circuit board and the area of the flexible circuit board are greatly increased, and the peripheral area is increased. The position of the connection pad and the flexible circuit board may interfere with the touch panel trademark area or the button and the through hole area also located in the peripheral area, thereby affecting the assembly of the touch panel.

採用本實施例提供的觸控面板，同樣，在減小第一軸向導電件信號衰減的同時，也不會增加軟性電路板接合墊的總數和軟性電路板的面積，並且在與軟性電路板耦合前，也可以方便檢測第一軸向導電件的電學特性。此外，第一軸向導電件和第二軸向導電件的兩端均與電路板耦合，相較於導電件只有一端與電路板耦合，可降低信號衰減，尤其適用於較大尺寸的觸控面板，可避免大尺寸觸控面板因導電件長度較大而信號衰減較大造成靈敏度較低；與第二實施例相同，本實施例中軟性電路板3的形狀可依連接墊的設置情況做相應改變，以順利避讓觸控面板商標區域(未繪出)或按鍵、通孔區域(未繪出)。With the touch panel provided by the embodiment, the signal attenuation of the first axial conductive member is reduced, and the total number of flexible circuit board bonding pads and the area of the flexible circuit board are not increased, and the flexible circuit board is used. It is also convenient to detect the electrical characteristics of the first axial conductive member before coupling. In addition, both ends of the first axial conductive member and the second axial conductive member are coupled to the circuit board, and only one end of the conductive member is coupled with the circuit board, which can reduce signal attenuation, and is particularly suitable for a larger size touch. The panel can prevent the large-size touch panel from being less sensitive due to the large length of the conductive member and the lower the signal attenuation.

However, the above embodiments may each have another embodiment, in which the first axial direction X may also be perpendicular to the first direction D1.

圖7是顯示本創作第一實施例之觸控面板連接墊所在位置之局部示意圖。在此實施例中，第一連接墊101和第二連接墊102的形狀相同。但在第四實施例中，如圖8所示，第一連接墊101和第二連接墊102的形狀不相同，例如為第一連接墊101為單邊開口式，而第二連接墊102嵌入到第一連接墊的該開口中，二者表現為相嵌設置。第一連接墊101和第二連接墊102採用相嵌式的形狀設計，因第二連接墊102嵌入到第一連接墊101中，可以降低第二連接墊在後期制程中斷裂的風險，提高觸控面板的可靠 度。FIG. 7 is a partial schematic view showing the position of the touch panel connection pad of the first embodiment of the present invention. In this embodiment, the first connection pad 101 and the second connection pad 102 have the same shape. However, in the fourth embodiment, as shown in FIG. 8, the shapes of the first connection pad 101 and the second connection pad 102 are different, for example, the first connection pad 101 is a single-sided open type, and the second connection pad 102 is embedded. In the opening to the first connection pad, the two appear to be in a nested arrangement. The first connection pad 101 and the second connection pad 102 are designed in a phase-embedded shape. Since the second connection pad 102 is embedded in the first connection pad 101, the risk of the second connection pad breaking in the later process can be reduced, and the touch is improved. Control panel reliability degree.
圖9是顯示本創作第五個實施例之觸控面板連接墊所在位置之局部示意圖。在上述的幾個實施例中，第二方向D2是垂直於第一方向D1，即電性連接於同一第一軸向導電件10的第一連接墊101和第二連接墊102的重心連線所指向的方向(如圖示D2方向)垂直於第一方向D1。但在此實施例中，第二方向D2是相交於第一方向D1，相交的角度為一銳角，因D1方向D2方向皆為雙指向，相交的角度以相交兩角的最小角為准。且第一連接墊101和第二連接墊102的形狀相應做改變，可為7字型如圖9A、梯形如圖9B，還可為三角形等。採用本實施例的技術方案，因第一連接墊101與第二連接墊102的周邊較長，可分散第一連接墊101和第二連接墊102周邊的應力，降低它們在後期制程中斷裂的風險，提高觸控面板的可靠度。FIG. 9 is a partial schematic view showing the position of the touch panel connection pad of the fifth embodiment of the present invention. In the above several embodiments, the second direction D2 is perpendicular to the first direction D1, that is, the center of gravity connection of the first connection pad 101 and the second connection pad 102 electrically connected to the same first axial conductive member 10. The direction pointed (as indicated by the D2 direction) is perpendicular to the first direction D1. However, in this embodiment, the second direction D2 intersects in the first direction D1, and the intersecting angle is an acute angle, since the D1 direction and the D2 direction are both bidirectional, and the intersecting angle is based on the minimum angle of the intersecting angles. The shapes of the first connection pad 101 and the second connection pad 102 are changed correspondingly, and may be a 7-shaped shape as shown in FIG. 9A, a trapezoid as shown in FIG. 9B, and may be a triangle or the like. According to the technical solution of the embodiment, since the perimeters of the first connection pad 101 and the second connection pad 102 are long, the stresses around the first connection pad 101 and the second connection pad 102 can be dispersed to reduce their breakage in the later process. Risk, improve the reliability of the touch panel.
圖10是顯示本創作第六個實施例之觸控面板連接墊所在位置之局部示意圖。在此實施例中，第二方向D2是平行於第一方向D1，且第一連接墊101和第二連接墊102的周邊為波浪狀。採用本實施例的技術方案，同樣可分散第一連接墊101和第二連接墊102周邊的應力，降低它們在後期制程中斷裂的風險，提高觸控面板的可靠度。FIG. 10 is a partial schematic view showing the position of the touch panel connection pad of the sixth embodiment of the present invention. In this embodiment, the second direction D2 is parallel to the first direction D1, and the periphery of the first connection pad 101 and the second connection pad 102 is wavy. With the technical solution of the embodiment, the stress around the first connection pad 101 and the second connection pad 102 can be dispersed, the risk of breakage in the post process can be reduced, and the reliability of the touch panel can be improved.
綜上所述，本創作透過將電性連接於同一導電件兩端的兩個連接墊設計到一起，而耦合到軟性電路板的同一接合墊上，在達到減小信號衰減的同時，又不會增加軟性電路板的接合墊數量或軟性電路板的面積，降低因此而產生的干涉觸控面板組裝的風險。此外，因電性連接於同一導電件的兩個連接墊在與軟性電路板耦合前彼此電性絕緣，可通過檢測儀器例如萬用表接觸這兩個連接墊來測量導電件的電學特性。而電性連接於同一導電件的兩個連接墊在相鄰方向和形狀上變形，更可降低它們在後期制程中斷裂的風險，提高觸控面板的可靠度。In summary, the present invention is designed by connecting two connection pads electrically connected to both ends of the same conductive member, and coupled to the same bonding pad of the flexible circuit board, while reducing signal attenuation, without increasing The number of bond pads of the flexible circuit board or the area of the flexible circuit board reduces the risk of interference with the assembly of the touch panel. In addition, since the two connection pads electrically connected to the same conductive member are electrically insulated from each other before being coupled with the flexible circuit board, the electrical characteristics of the conductive member can be measured by a detecting instrument such as a multimeter contacting the two connection pads. The two connection pads electrically connected to the same conductive member are deformed in adjacent directions and shapes, which further reduces the risk of breakage in the later process and improves the reliability of the touch panel.
