第1A圖為根據本創作之第一實施方式之觸控面板100的剖面示意圖。觸控面板100包含第一導電網格層110、第二導電網格層130以及絕緣層120。絕緣層120將第一導電網格層110與第二導電網格層130分隔開來。於本實施方式中，第一導電網格層110是例如作為觸控面板100的Y軸向(垂直軸向)電極，而第二導電網格層130是例如作為觸控面板100的X軸向(水平軸向)電極。 FIG. 1A is a schematic cross-sectional view of the touch panel 100 according to the first embodiment of the present invention.

In this embodiment, the first conductive mesh layer 110 is, for example, a Y-axis (vertical axis) electrode of the touch panel 100, and the second conductive mesh layer 130 is, for example, an X-axis direction of the touch panel 100 (Horizontal axis) electrode.
第1B圖為第1A圖之觸控面板100的上視示意圖。具體而言，第1A圖為沿第1B圖之線1A-1A之剖面圖。第1C圖為第1B圖之觸控面板100的第一導電網格層110的上視示意圖。同時參考第1A圖至第1C圖。第一導電網格層110包含至少一第一觸控電極112以及至少一第一虛設電極114，分別具有由導電材料構成的複數個網格。第一觸控電極112與第一虛設電極114互相電性分離。具體而言，第一觸控電極112與第一虛設電極114之間具有間隙G1，而將兩者分離。補充說明的是，第一導電網格層110是由一整層完整的導電網格材料層經圖案化後所形成，其中第一觸控電極112的佈設範圍是定義為一功能區域，而第一虛設電極114的佈設範圍則是定義為一非功能區域。 FIG. 1B is a schematic top view of the touch panel 100 of FIG. 1A. Specifically, FIG. 1A is a cross-sectional view taken along the line 1A-1A of FIG. 1B. FIG. 1C is a schematic top view of the first conductive mesh layer 110 of the touch panel 100 of FIG. 1B. Also refer to Figures 1A to 1C. The first conductive grid layer 110 includes at least one first touch electrode 112 and at least one first dummy electrode 114, each having a plurality of grids made of conductive material. The first touch electrode 112 and the first dummy electrode 114 are electrically separated from each other. Specifically, there is a gap G1 between the first touch electrode 112 and the first dummy electrode 114 to separate the two. It is added that the first conductive mesh layer 110 is formed by patterning a complete conductive mesh material layer, wherein the layout range of the first touch electrode 112 is defined as a functional area, and the first The layout range of a dummy electrode 114 is defined as a non-functional area.
於部分實施方式中，第一導電網格層110由複數個單位區域UA1以矩陣排列而形成，其中每一單位區域UA1 涵蓋一個第一觸控電極112以及二個第一虛設電極114，第一觸控電極112設置位於二個第一虛設電極114之間。以下僅就一個單位區域UA1來介紹第一觸控電極112以及第一虛設電極114的設計。 In some embodiments, the first conductive mesh layer 110 is formed by a plurality of unit regions UA1 arranged in a matrix, wherein each unit region UA1 It covers one first touch electrode 112 and two first dummy electrodes 114. The first touch electrode 112 is disposed between the two first dummy electrodes 114. The design of the first touch electrode 112 and the first dummy electrode 114 will be described below for only one unit area UA1.
第一觸控電極112具有多個網格節點112a(即網格交會點)以及連接網格節點112a的網格線條112b(即網格交會線)。於部分實施方式中，一個完整網格定義是由四個網格節點112a及四條網格線條112b所組成的一封閉網格，並且相鄰接的兩個完整網格是共用兩個網格節點112a及一條網格線條112b，或者共用一個網格節點112a，換句話說，相鄰接的兩個完整網格是透過兩個網格節點112a及一條網格線條112b來形成鄰邊相接的態樣，或者透過一個網格節點112a來形成端點相接的態樣。 The first touch electrode 112 has a plurality of grid nodes 112a (ie grid intersection points) and grid lines 112b (ie grid intersection lines) connecting the grid nodes 112a. In some embodiments, a complete grid definition is a closed grid composed of four grid nodes 112a and four grid lines 112b, and two adjacent complete grids share two grid nodes 112a and a grid line 112b, or share a grid node 112a, in other words, two adjacent grids are connected by two grid nodes 112a and a grid line 112b Aspect, or through a grid node 112a to form an aspect where the endpoints are connected.
第一觸控電極112的網格節點112a是週期性設置，也就是網格節點112a的落點位置是依據特定的規則來排列設置，例如：在水平軸向上，相鄰的兩個網格節點112a是間隔一第一距離；而在垂直軸向上，相鄰的兩個網格節點112a是間隔一第二距離，其中第一距離可等於或不等於第二距離，藉此讓網格節點112a至少在相同軸向上的設置都是具有週期性的，整體來看，所有網格節點112a即是呈現週期性的設置並呈矩陣型態分布。 The grid nodes 112a of the first touch electrode 112 are periodically set, that is, the landing points of the grid nodes 112a are arranged according to specific rules, for example: on the horizontal axis, two adjacent grid nodes 112a is separated by a first distance; and on the vertical axis, two adjacent grid nodes 112a are separated by a second distance, where the first distance may or may not be equal to the second distance, thereby allowing the grid node 112a At least the settings in the same axis are periodic. Overall, all grid nodes 112a are periodically arranged and distributed in a matrix pattern.
第一觸控電極112的網格線條112b是規則性設置，也就是讓網格線條112b採用同一種線形來設計，例如可採用直線、折線、弧線、曲線及雲形線等線形的任一種來設計。 於本實施方式中，第一觸控電極112的各個完整網格的網格線條112b的線形及長度一致，而使第一觸控電極112的各個完整網格的形狀相同。於本實施方式中，以直線的網格線條112b為例，網格的形狀為菱形。藉由此設計，可使不同單位區域UA1內的第一觸控電極112的整體電容值與電阻值一致。補充說明的是，第一觸控電極112中未能構成完整網格的網格線條112b，由於其並未與其他完整網格形成完整的電性連接，因此其對第一觸控電極112的整體電容值與電阻值的影響可忽略不計。 The grid lines 112b of the first touch electrode 112 are arranged regularly, that is, the grid lines 112b are designed with the same line shape, for example, any one of straight lines, polylines, arcs, curves, and cloud-shaped lines can be used to design . In this embodiment, the lines and lengths of the grid lines 112b of the complete grids of the first touch electrode 112 are the same, and the shapes of the complete grids of the first touch electrode 112 are the same. In this embodiment, taking a straight grid line 112b as an example, the shape of the grid is a rhombus. With this design, the overall capacitance value and resistance value of the first touch electrodes 112 in different unit areas UA1 can be made consistent. It is added that the first touch electrode 112 fails to form a complete grid line 112b. Since it does not form a complete electrical connection with other complete grids, its The effect of overall capacitance and resistance is negligible.
承上所述，通過網格節點112a的週期性設置以及網格線條112b的規則性設置，使得第一觸控電極112中的所有完整網格的形狀完全相同而呈規則排列。 As described above, through the periodic setting of the grid nodes 112a and the regular setting of the grid lines 112b, all the complete grids in the first touch electrodes 112 have the same shape and are regularly arranged.
第一虛設電極114具有多個網格節點114a(即網格交會點)以及連接網格節點114a的網格線條114b(即網格交會線)。第一虛設電極114中對於完整網格的定義與第一觸控電極112的定義相同，在此就不再加以贅述。第一虛設電極114的網格節點114a是週期性設置並呈矩陣型態分布，使不同單位區域UA1內的第一虛設電極114的節點電容值一致。此外，第一虛設電極114的網格線條114b是不規則性設置，具體也就是設計第一虛設電極114包含至少兩條不同線形的網格線條114b，其中線形可包含直線、折線、弧線、曲線及雲形線等線形。如此一來，雖然第一虛設電極114的所有完整網格的網格結點114a是週期性設置，但因至少包含兩條不同線形的網格線條114b，因此可破壞整體的一致性，讓第一虛設電極114 的至少兩個完整網格的形狀不同。藉此，可避免規則性排列的網格造成視覺上的干擾，例如摩爾紋(Moiré pattern)。於部分實施方式中，第一虛設電極114的所有網格線條114b較佳是隨機由直線、折線、弧線、曲線及雲形線等線形來佈設，讓第一虛設電極114的所有完整網格的形狀更具不規則性，更能有效地降低視覺上的干擾。 The first dummy electrode 114 has a plurality of grid nodes 114a (ie grid intersection points) and grid lines 114b (ie grid intersection lines) connecting the grid nodes 114a. The definition of the complete grid in the first dummy electrode 114 is the same as that of the first touch electrode 112, which will not be repeated here. The grid nodes 114a of the first dummy electrodes 114 are periodically arranged and distributed in a matrix pattern, so that the node capacitance values of the first dummy electrodes 114 in different unit areas UA1 are consistent. In addition, the grid lines 114b of the first dummy electrode 114 are irregularly arranged, that is, the design of the first dummy electrode 114 includes at least two grid lines 114b with different linear shapes, wherein the linear shape may include straight lines, polylines, arcs, and curves And cloud-shaped lines. In this way, although the grid nodes 114a of all complete grids of the first dummy electrode 114 are periodically set, since at least two grid lines 114b with different linear shapes are included, the overall consistency can be destroyed, so that the first A dummy electrode 114 The shape of at least two complete grids are different. In this way, it is possible to avoid the visual interference caused by regularly arranged grids, such as moiré patterns. In some embodiments, all grid lines 114b of the first dummy electrode 114 are preferably randomly arranged by lines such as straight lines, polylines, arcs, curves, and splines, so that all the complete grid shapes of the first dummy electrode 114 It is more irregular and can effectively reduce visual interference.
承上所述，就第一觸控電極112及第一虛設電極114的網格結構來看，第一虛設電極114的至少一個完整網格的形狀會不同於第一觸控電極112的任一完整網格的形狀。舉例而言，第一虛設電極114的網格線條114b至少包含曲線及雲形線的線形，而第一觸控電極112的網格線條112b則皆為直線的線形，如此一來，讓功能區域和非功能區域所呈現的整體網格態樣得以不同，進而產生視覺上的差異。 As described above, in terms of the grid structure of the first touch electrodes 112 and the first dummy electrodes 114, the shape of at least one complete grid of the first dummy electrodes 114 will be different from any of the first touch electrodes 112 The shape of the complete grid. For example, the grid lines 114b of the first dummy electrodes 114 include at least curved and cloud-shaped lines, and the grid lines 112b of the first touch electrodes 112 are all linear lines. In this way, the functional area and The overall grid appearance presented by the non-functional area is different, which in turn produces visual differences.
第LD圖為第1B圖之觸控面板100的第二導電網格層130的上視示意圖。本實施方式中的第二導電網格層130的設計態樣大致與第一導電網格層110相同，差異點在於兩者是作為不同軸向的電極層，因此，以下將簡化說明。第二導電網格層130包含至少一第二觸控電極132以及至少一第二虛設電極134，分別具有由導電材料構成的複數個網格。第二觸控電極132與第二虛設電極134互相電性分離。具體而言，第二觸控電極132與第二虛設電極134之間具有間隙G2，而將兩者分離。同樣的，第二導電網格層130是由一整層完整的導電網格材料層經圖案化後所形成，其中第二觸控電極132的佈設範圍是定義為一功能區域，而第二虛設電極134的佈設範圍則是 定義為一非功能區域。 FIG. LD is a schematic top view of the second conductive mesh layer 130 of the touch panel 100 of FIG. 1B. The design of the second conductive mesh layer 130 in this embodiment is substantially the same as that of the first conductive mesh layer 110. The difference is that the two are electrode layers in different axial directions. Therefore, the following description will be simplified. The second conductive grid layer 130 includes at least one second touch electrode 132 and at least one second dummy electrode 134, each having a plurality of grids made of conductive material. The second touch electrode 132 and the second dummy electrode 134 are electrically separated from each other. Specifically, there is a gap G2 between the second touch electrode 132 and the second dummy electrode 134 to separate the two. Similarly, the second conductive mesh layer 130 is formed by patterning a complete conductive mesh material layer, wherein the layout range of the second touch electrode 132 is defined as a functional area, and the second dummy The layout range of electrode 134 is Defined as a non-functional area.
於部分實施方式中，第二導電網格層130由複數個單位區域UA2以矩陣排列而形成，其中每一單位區域UA2涵蓋一個第二觸控電極132以及二個第二虛設電極134，第二觸控電極132設置位於二個第二虛設電極134之間。以下僅就一個單位區域UA2來介紹第二觸控電極132以及第二虛設電極134的設計。 In some embodiments, the second conductive mesh layer 130 is formed by a plurality of unit areas UA2 arranged in a matrix, wherein each unit area UA2 covers one second touch electrode 132 and two second dummy electrodes 134, the second The touch electrode 132 is disposed between the two second dummy electrodes 134. The following describes the design of the second touch electrode 132 and the second dummy electrode 134 for only one unit area UA2.
如同第一觸控電極112的設置，第二觸控電極132具有多個網格節點132a(即網格交會點)以及連接網格節點132a的網格線條132b(即網格交會線)。第二觸控電極132的所有網格節點132a是週期性設置並呈矩陣型態分布。此外，第二觸控電極132的網格線條132b是規則性設置，也就是讓網格線條132b採用同一種線形來設計，例如可採用直線、折線、弧線、曲線及雲形線等線形的任一種來設計。於本實施方式中，第二觸控電極132的各個完整網格的網格線條132b的線形及長度一致，而使第二觸控電極132的各個完整網格的形狀相同。於本實施方式中，以直線的網格線條132b為例，網格的形狀為菱形。藉由此設計，可使不同單位區域UA2內的第二觸控電極132的整體電容值與電阻值一致。承上所述，通過網格節點132a的週期性設置以及網格線條132b的規則性設置，使得第二觸控電極132中的所有完整網格的形狀完全相同而呈規則排列。 As with the arrangement of the first touch electrode 112, the second touch electrode 132 has a plurality of grid nodes 132a (ie grid intersection points) and grid lines 132b (ie grid intersection lines) connecting the grid nodes 132a. All grid nodes 132a of the second touch electrode 132 are arranged periodically and distributed in a matrix pattern. In addition, the grid lines 132b of the second touch electrode 132 are set regularly, that is, the grid lines 132b are designed with the same line shape, for example, any of linear, polyline, arc, curve, and cloud-shaped lines can be used To design. In this embodiment, the lines and lengths of the grid lines 132b of the complete grids of the second touch electrode 132 are the same, and the shapes of the complete grids of the second touch electrode 132 are the same. In the present embodiment, taking a straight grid line 132b as an example, the shape of the grid is a rhombus. With this design, the overall capacitance value and resistance value of the second touch electrodes 132 in different unit areas UA2 can be made consistent. As described above, through the periodic setting of the grid nodes 132a and the regular setting of the grid lines 132b, all the complete grids in the second touch electrodes 132 have the same shape and are regularly arranged.
如同第一虛設電極114的設置，第二虛設電極134具有多個網格節點134a(即網格交會點)以及連接網格節點 134a的網格線條134b(即網格交會線)。第二虛設電極134的網格節點134a是週期性設置並呈矩陣型態分布，使不同單位區域UA2內的第二虛設電極134的節點電容一致。此外，第二虛設電極134的網格線條134b是不規則性設置，具體也就是設計第二虛設電極134包含至少兩條不同線形的網格線條134b，其中線形可包含直線、折線、弧線、曲線及雲形線等線形。如此一來，雖然第二虛設電極134的所有完整網格的網格結點134a是週期性設置，但因至少包含兩條不同線形的網格線條134b，因此可破壞整體的一致性，讓第二虛設電極134的至少兩個完整網格的形狀不同。藉此，可避免規則性排列的網格造成視覺上的干擾，例如摩爾紋(Moiré pattern)。 Like the arrangement of the first dummy electrode 114, the second dummy electrode 134 has a plurality of grid nodes 134a (ie grid intersection points) and connected grid nodes The grid line 134b of 134a (that is, the grid intersection line). The grid nodes 134a of the second dummy electrode 134 are periodically arranged and distributed in a matrix pattern, so that the node capacitances of the second dummy electrodes 134 in different unit areas UA2 are consistent. In addition, the grid lines 134b of the second dummy electrode 134 are irregularly arranged, specifically, the design of the second dummy electrode 134 includes at least two grid lines 134b of different linear shapes, wherein the linear shape may include straight lines, polylines, arcs, curves And cloud-shaped lines. In this way, although all the grid nodes 134a of the complete grid of the second dummy electrode 134 are periodically set, since at least two grid lines 134b with different linear shapes are included, the overall consistency can be destroyed, so that the first At least two complete grids of the two dummy electrodes 134 have different shapes. In this way, it is possible to avoid the visual interference caused by regularly arranged grids, such as moiré patterns.
承上所述，就第二觸控電極132及第二虛設電極134的網格結構來看，第二虛設電極134的至少一個完整網格的形狀不同於第二觸控電極132的任一完整網格的形狀。舉例而言，第二虛設電極134的網格線條134b至少包含曲線及雲形線的線形，而第二觸控電極132的網格線條132b則皆為直線的線形，如此一來，讓功能區域和非功能區域所呈現的整體網格態樣得以不同，進而產生視覺上的差異。 As described above, in terms of the grid structure of the second touch electrode 132 and the second dummy electrode 134, the shape of at least one complete grid of the second dummy electrode 134 is different from any complete shape of the second touch electrode 132 The shape of the grid. For example, the grid lines 134b of the second dummy electrode 134 include at least curved and cloud-shaped lines, and the grid lines 132b of the second touch electrode 132 are all straight lines, so that the functional area and The overall grid appearance presented by the non-functional area is different, which in turn produces visual differences.
參照第1B圖，在第一導電網格層110和第二導電網格層130上下重疊設置的情況下在垂直觸控面板方向上，只有在第一觸控電極112與第二觸控電極132相交的重疊區域A1是存在呈規則排列且形狀相同的完整網格。然而，其他重疊區域如第一虛設電極114與第二觸控電極132相交的重疊區域A21以及第一觸控電極112與第二虛設電極134相交的重疊 區域A22，此兩區域因為存在一層呈規則排列但形狀不全相同的完整網格，因此整體也就呈現出不規則的視覺效果。此外，第一虛設電極114與第二虛設電極134相交的重疊區域A23更是存在兩層呈規則排列但形狀不全相同的完整網格，因此整體也更是呈現出不規則的視覺效果。在部分實施方式中，重疊區域A1的面積占一個單位區域(UA)的整體面積小於或等於5.7%。通過本實施方式的設計，重疊區域A1僅僅佔用較小的面積，並且一個重疊區域A1是由呈現不規則視覺效果的重疊區域A21~A23所包圍，讓多個重疊區域A1彼此之間得以有效地被隔開，有助於維持觸控面板100整體的視覺效果，可避免規則性圖形設置所導致的摩爾紋問題。 Referring to FIG. 1B, in the case where the first conductive mesh layer 110 and the second conductive mesh layer 130 are arranged one above the other, in the vertical touch panel direction, only the first touch electrode 112 and the second touch electrode 132 The overlapping overlapping area A1 is a complete grid with regular arrangement and the same shape. However, other overlapping areas such as the overlapping area A21 where the first dummy electrode 114 intersects the second touch electrode 132 and the overlap where the first touch electrode 112 intersects the second dummy electrode 134 Area A22, these two areas have a complete grid that is regularly arranged but not all of the same shape, so the whole will show an irregular visual effect. In addition, in the overlapping area A23 where the first dummy electrode 114 and the second dummy electrode 134 intersect, there are two complete grids that are regularly arranged but the shapes are not the same, so the whole also exhibits an irregular visual effect. In some embodiments, the area of the overlapping area A1 accounts for less than or equal to 5.7% of the total area of one unit area (UA). Through the design of this embodiment, the overlapping area A1 occupies only a small area, and one overlapping area A1 is surrounded by overlapping areas A21 to A23 that exhibit irregular visual effects, so that the multiple overlapping areas A1 can be effectively Being separated helps to maintain the overall visual effect of the touch panel 100 and avoids the moiré problem caused by regular graphic settings.
於本創作之部分實施方式中，第一導電網格層110以及第二導電網格層130的網格節點互相交錯，而不互相重疊。舉例而言，在重疊區域A1中，第一觸控電極112的網格節點112a於絕緣層120之上表面的投影不與第二觸控電極132的網格節點132a於絕緣層120之上表面的投影重疊。在重疊區域A21中，第一虛設電極114的網格節點114a於絕緣層120之上表面的投影不與第二觸控電極132的網格節點132a於絕緣層120之上表面的投影重疊。在重疊區域A22中，第一觸控電極112的網格節點112a於絕緣層120之上表面的投影不與第二虛設電極134的網格節點134a於絕緣層120之上表面的投影重疊。在重疊區域A23中，第一虛設電極114的網格節點114a於絕緣層120之上表面的投影不與第二虛設電極134的網格節點134a於絕緣層120之上表面的投影重疊。藉此，讓原本呈現不 規則視覺效果的重疊區域A21~A23在第一導電網格層110以及第二導電網格層130的網格節點不互相重疊的情況下可進一步造成不規則化的效果。當然，不應以此限制本創作的範圍，於其他實施方式中，第一導電網格層110以及第二導電網格層130的網格節點可以是互相重疊。 In some embodiments of the present invention, the grid nodes of the first conductive grid layer 110 and the second conductive grid layer 130 are interlaced with each other, and do not overlap each other. For example, in the overlapping area A1, the projection of the grid node 112a of the first touch electrode 112 on the upper surface of the insulating layer 120 is not the same as the grid node 132a of the second touch electrode 132 on the upper surface of the insulating layer 120 Of projections overlap. In the overlapping area A21, the projection of the grid node 114a of the first dummy electrode 114 on the upper surface of the insulating layer 120 does not overlap with the projection of the grid node 132a of the second touch electrode 132 on the upper surface of the insulating layer 120. In the overlapping area A22, the projection of the grid node 112a of the first touch electrode 112 on the upper surface of the insulating layer 120 does not overlap with the projection of the grid node 134a of the second dummy electrode 134 on the upper surface of the insulating layer 120. In the overlapping area A23, the projection of the mesh node 114a of the first dummy electrode 114 on the upper surface of the insulating layer 120 does not overlap with the projection of the mesh node 134a of the second dummy electrode 134 on the upper surface of the insulating layer 120. With this, the original The overlapping areas A21 to A23 of the regular visual effect can further cause an irregular effect when the grid nodes of the first conductive grid layer 110 and the second conductive grid layer 130 do not overlap each other. Of course, it should not be used to limit the scope of this creation. In other embodiments, the grid nodes of the first conductive grid layer 110 and the second conductive grid layer 130 may overlap each other.
於本創作之部分實施方式中，第一導電網格層110以及第二導電網格層130可例如是由銅層經光刻微影及蝕刻之圖案化製程而形成。或者，於其他實施方式中，可以直接採用印刷方式，以液態金屬油墨來進行圖案化印刷而形成。當然不應以此限制本創作之範圍，於其他實施方式中，導電網格材料層的材料可以採用其他導電性良好的金屬或金屬合金，例如銀、鎳、鈦鎢合金等。 In some embodiments of the present invention, the first conductive mesh layer 110 and the second conductive mesh layer 130 may be formed by a patterning process of a copper layer through photolithography and etching, for example. Alternatively, in other embodiments, the printing method may be used directly, and the liquid metal ink may be used for pattern printing. Of course, it should not be used to limit the scope of this creation. In other embodiments, the material of the conductive mesh material layer may use other metals or metal alloys with good conductivity, such as silver, nickel, titanium-tungsten alloy, and the like.
於本創作之部分實施方式中，絕緣層120可以是硬性基板，例如玻璃基板或聚對苯二甲酸乙二酯(polyethylene terephthalate；PET)基板。或者，於部分實施方式中，絕緣層120可以是適當軟性基板。舉例而言，絕緣層120可以是軟性聚對苯二甲酸乙二酯(PET)或者聚亞醯胺(polyimide；PI)基板。此外，於部分實施方式中，絕緣層120也可以是一黏著層，例如光學膠。對此，若絕緣層120是採用黏著層的設計，就觸控面板100的結構而言，第一導電網格層110及第二導電網格層130是例如先分別形成在一永久性或暫時性的承載基板(圖未示)，之後再透過黏著層來相互貼合。 In some embodiments of the present invention, the insulating layer 120 may be a rigid substrate, such as a glass substrate or a polyethylene terephthalate (PET) substrate. Alternatively, in some embodiments, the insulating layer 120 may be a suitable flexible substrate. For example, the insulating layer 120 may be a flexible polyethylene terephthalate (PET) or polyimide (PI) substrate. In addition, in some embodiments, the insulating layer 120 may also be an adhesive layer, such as optical glue. In this regard, if the insulating layer 120 is designed with an adhesive layer, as far as the structure of the touch panel 100 is concerned, the first conductive mesh layer 110 and the second conductive mesh layer 130 are first formed in a permanent or temporary The carrier substrate (not shown) is then bonded to each other through the adhesive layer.
於本實施方式中，第一虛設電極114的網格節點114a的週期與第一觸控電極112的網格節點112a的週期相 同。舉例而言，在水平軸向上，相鄰兩個網格節點114a之間的間距大約等於相鄰兩個網格節點112a的間距；在垂直軸向上，相鄰兩個網格節點114a之間的間距大約等於相鄰兩個網格節點112a的間距。類似地，第二虛設電極134的網格節點134a的週期與第二觸控電極132的網格節點132a的週期相同。舉例而言，在水平軸向上，相鄰兩個網格節點134a之間的間距大約等於相鄰兩個網格節點132a的間距；在垂直軸向上，相鄰兩個網格節點134a之間的間距大約等於相鄰兩個網格節點132a的間距。當然不應以此限制本創作之範圍，於其他實施方式中，兩者的週期可不相同。 In this embodiment, the period of the mesh node 114a of the first dummy electrode 114 is the same as the period of the mesh node 112a of the first touch electrode 112 with. For example, in the horizontal axis, the distance between two adjacent grid nodes 114a is approximately equal to the distance between two adjacent grid nodes 112a; in the vertical axis, the distance between two adjacent grid nodes 114a The pitch is approximately equal to the pitch of two adjacent grid nodes 112a. Similarly, the period of the grid node 134a of the second dummy electrode 134 is the same as the period of the grid node 132a of the second touch electrode 132. For example, in the horizontal axis, the distance between two adjacent grid nodes 134a is approximately equal to the distance between two adjacent grid nodes 132a; in the vertical axis, the distance between two adjacent grid nodes 134a The pitch is approximately equal to the pitch of two adjacent grid nodes 132a. Of course, it should not be used to limit the scope of this creation. In other embodiments, the periods of the two may be different.

FIG. 2B is a schematic top view of the unit area UA2 of the second conductive mesh layer 130 of the touch panel 100 according to the second embodiment of the present invention. This embodiment is similar to the first embodiment, except that, as shown in FIG. 2A, in this embodiment, the period of the mesh node 114a of the first dummy electrode 114 is different from the mesh node 112a of the first touch electrode 112 The period of the grid node 114a of the first dummy electrode 114 is greater than the period of the grid node 112a of the first touch electrode 112. Specifically, here, the period of the grid node 114a of the first dummy electrode 114 is twice the period of the grid node 112a of the first touch electrode 112, that is, whether in the horizontal axis or the vertical axis, the phase The distance between two adjacent grid nodes 114a is equal to twice the distance between two adjacent grid nodes 112a. Here, the period of the mesh node 114a of each first dummy electrode 114 of the unit area UA1 is still the same.
類似地，如第2B圖所示，第二虛設電極134的網格節點134a的週期大於第二觸控電極132的網格節點132a的週期。舉例而言，第二虛設電極134的網格節點134a的週期為第二觸控電極132的網格節點132a的週期的兩倍，也就是不管在水平軸向或垂直軸向上，相鄰兩個網格節點134a之間的間距是等於相鄰兩個網格節點132a的間距的兩倍。單位區域UA2的各個第二虛設電極134的網格節點134a的週期仍相同。 Similarly, as shown in FIG. 2B, the period of the mesh node 134a of the second dummy electrode 134 is greater than the period of the mesh node 132a of the second touch electrode 132. For example, the period of the grid node 134a of the second dummy electrode 134 is twice that of the grid node 132a of the second touch electrode 132, that is, whether adjacent to the horizontal axis or the vertical axis, two adjacent The spacing between grid nodes 134a is equal to twice the spacing between two adjacent grid nodes 132a. The period of the mesh node 134a of each second dummy electrode 134 of the unit area UA2 is still the same.
本實施方式之其他細節大致如前所述，在此不再贅言。 Other details of this embodiment are generally as described above, and will not be repeated here.
第3A圖為根據本創作之第三實施方式之觸控面板的第一導電網格層110的單位區域UA1的上視示意圖。第3B圖為根據本創作之第三實施方式之觸控面板的第二導電網格層130的單位區域UA2的上視示意圖。本實施方式與第一實施方式相似，差別在於：如第3A圖所示，本實施方式中，第一虛設電極114的網格節點114a的週期不同於第一觸控電極112的網格節點112a的週期，第一虛設電極114的網格節點114a的週期小於第一觸控電極112的網格節點112a的週期。具體而言，於此，第一觸控電極112的網格節點112a的週期為的第一虛設電極114的網格節點114a週期的兩倍，也就是不管在水平軸向或垂直軸向上，相鄰兩個網格節點112a之間的間距是等於相鄰兩個網格節點114a的間距的兩倍。於此，單位區域UA1的各個第一虛設電極114的網格節點114a的週期仍相同。 FIG. 3A is a schematic top view of the unit area UA1 of the first conductive mesh layer 110 of the touch panel according to the third embodiment of the present invention. FIG. 3B is a schematic top view of the unit area UA2 of the second conductive mesh layer 130 of the touch panel according to the third embodiment of the present invention. This embodiment is similar to the first embodiment, except that, as shown in FIG. 3A, in this embodiment, the period of the mesh node 114a of the first dummy electrode 114 is different from the mesh node 112a of the first touch electrode 112 The period of the grid node 114a of the first dummy electrode 114 is less than the period of the grid node 112a of the first touch electrode 112. Specifically, here, the period of the grid node 112a of the first touch electrode 112 is twice that of the grid node 114a of the first dummy electrode 114, that is, regardless of the horizontal axis or the vertical axis, the phase The distance between two adjacent grid nodes 112a is equal to twice the distance between two adjacent grid nodes 114a. Here, the period of the mesh node 114a of each first dummy electrode 114 of the unit area UA1 is still the same.
類似地，如第3B圖所示，第二虛設電極134的網格節點134a的週期小於第二觸控電極132的網格節點132a的 週期。舉例而言，第二觸控電極132的網格節點132a的週期為第二虛設電極134的網格節點134a的週期的兩倍，也就是不管在水平軸向或垂直軸向上，相鄰兩個網格節點132a之間的間距是等於相鄰兩個網格節點134a的間距的兩倍。單位區域UA2的各個第二虛設電極134的網格節點134a的週期仍相同。 Similarly, as shown in FIG. 3B, the period of the grid node 134a of the second dummy electrode 134 is smaller than that of the grid node 132a of the second touch electrode 132 cycle. For example, the period of the grid node 132a of the second touch electrode 132 is twice that of the grid node 134a of the second dummy electrode 134, that is, whether adjacent to the horizontal axis or the vertical axis, two adjacent The spacing between grid nodes 132a is equal to twice the spacing between two adjacent grid nodes 134a. The period of the mesh node 134a of each second dummy electrode 134 of the unit area UA2 is still the same.
本實施方式之其他細節大致如前所述，在此不再贅言。 Other details of this embodiment are generally as described above, and will not be repeated here.

FIG. 4B is a schematic top view of the unit area UA2 of the second conductive mesh layer 130 of the touch panel according to the fourth embodiment of the present invention. This embodiment is similar to the first embodiment, with the difference that, as shown in FIG. 4A, in this embodiment, the grid lines 112b of the first touch electrodes 112 are curvilinear. The shape and size of each complete grid of the first touch electrode 112 remain the same. With this design, the overall capacitance value and resistance value of the first touch electrodes 112 in different unit areas UA1 can be made consistent. Similarly, as shown in FIG. 4B, in this embodiment, the grid lines 132b of the second touch electrodes 132 are curved lines. The shape and size of each complete grid of the second touch electrode 132 remain the same. With this design, the overall capacitance value and resistance value of the second touch electrodes 132 in different unit areas UA2 can be made consistent.
於本實施方式中，第一虛設電極114的網格節點114a的週期與第一觸控電極112的網格節點112a的週期相同。舉例而言，在水平軸向上，相鄰兩個網格節點114a之間的間距大約等於相鄰兩個網格節點112a的間距；在垂直軸向 上，相鄰兩個網格節點114a之間的間距大約等於相鄰兩個網格節點112a的間距。類似地，第二虛設電極134的網格節點134a的週期與第二觸控電極132的網格節點132a的週期相同。舉例而言，在水平軸向上，相鄰兩個網格節點134a之間的間距大約等於相鄰兩個網格節點132a的間距；在垂直軸向上，相鄰兩個網格節點134a之間的間距大約等於相鄰兩個網格節點132a的間距。當然不應以此限制本創作之範圍，於其他實施方式中，兩者的週期可不相同。 In this embodiment, the period of the mesh node 114a of the first dummy electrode 114 is the same as the period of the mesh node 112a of the first touch electrode 112. For example, in the horizontal axis, the distance between two adjacent grid nodes 114a is approximately equal to the distance between two adjacent grid nodes 112a; in the vertical axis Above, the spacing between two adjacent grid nodes 114a is approximately equal to the spacing between two adjacent grid nodes 112a. Similarly, the period of the grid node 134a of the second dummy electrode 134 is the same as the period of the grid node 132a of the second touch electrode 132. For example, in the horizontal axis, the distance between two adjacent grid nodes 134a is approximately equal to the distance between two adjacent grid nodes 132a; in the vertical axis, the distance between two adjacent grid nodes 134a The pitch is approximately equal to the pitch of two adjacent grid nodes 132a. Of course, it should not be used to limit the scope of this creation. In other embodiments, the periods of the two may be different.
本實施方式之其他細節大致如前所述，在此不再贅言。 Other details of this embodiment are generally as described above, and will not be repeated here.
本創作之多個實施方式中，在至少一導電網格層中，設計非功能區域的導電網格的形狀為不規則性的，可避免整層規則性圖形設置所導致的摩爾紋問題。進一步的，當觸控面板與顯示面板重疊設置時，本創作之多個實施方式的設計更可避免觸控面板的導電網格層的導電網格與顯示面板的像素(Pixel)形成規則性圖形的重疊，進一步降低摩爾紋發生的機會。此外，雖然非功能區域的導電網格的形狀設計為非規則性，但網格節點仍設計為週期性設置並呈矩陣型態分布，藉此能維持觸控面板整體的電容值的均勻性避免非功能區域的虛設電極影響觸控感測結果的判斷。 In various embodiments of the present invention, in at least one conductive mesh layer, the shape of the conductive mesh in the non-functional area is irregular, which can avoid the moiré problem caused by the regular pattern setting of the entire layer. Further, when the touch panel and the display panel are overlapped, the designs of the embodiments of the present invention can further prevent the conductive grid of the conductive grid layer of the touch panel from forming regular patterns with pixels of the display panel The overlap further reduces the chance of moiré occurrence. In addition, although the shape of the conductive grid of the non-functional area is designed to be irregular, the grid nodes are still designed to be periodically arranged and distributed in a matrix pattern, thereby maintaining the uniformity of the capacitance value of the entire touch panel to avoid The dummy electrode in the non-functional area affects the judgment of the touch sensing result.
雖然本創作已以多種實施方式揭露如上，然其並非用以限定本創作，任何熟習此技藝者，在不脫離本創作之精神和範圍內，當可作各種之更動與潤飾，因此本創作之保護範圍當視後附之申請專利範圍所界定者為準。 Although this creation has been disclosed in various ways as above, it is not intended to limit this creation. Anyone who is familiar with this skill can make various changes and retouching without departing from the spirit and scope of this creation. The scope of protection shall be deemed as defined by the scope of the attached patent application.
