Description

觸控面板 Touch panel

本發明係關於一種觸控面板，尤指一種具有不規則三角形之網格的觸控面板。 The present invention relates to a touch panel, and more particularly to a touch panel having a grid of irregular triangles.

近年來，觸控感應技術迅速地發展，許多消費性電子產品例如行動電話(mobile phone)、衛星導航系統(GPS navigator system)、平板電腦(tablet PC)、個人數位助理(PDA)以及筆記型電腦(laptop PC)等均有與觸控功能結合的產品推出。於上述各電子產品中，主要係將原有的顯示功能與觸控感應功能進行整合而形成觸控顯示裝置。目前觸控面板的技術發展非常多樣化，較常見的技術包括電阻式、電容式以及光學式等。在習知的電阻式或電容式觸控面板中，進行觸控偵測的感測電極為了避免影響所搭配的顯示效果一般係以透明導電材料例如氧化銦錫(indium tin oxide,ITO)所形成，由於透明導電材料之電阻率一般仍較金屬導電材料高，故使用透明導電材料形成感應電極會發生整體阻值過高而影響到反應速度等問題。因此，目前相關領域亦有開發出以金屬線路配置而成的金屬網格(metal mesh)來取代透明導電材料形成電極之設計來提升反應速度。然而，一般的金屬網格圖案係由規則的圖形例如正六邊形或正方形等圖形重複拼接而成，因此當此類金屬網格圖案與顯示面板進行搭配時，若各金屬網格的邊長與顯示面板中的畫素大小相近時，容易發生疊紋(Moiré)效應而影響整體的顯示品質。 In recent years, touch sensing technology has rapidly developed, and many consumer electronic products such as mobile phones, GPS navigator systems, tablet PCs, personal digital assistants (PDAs), and notebook computers (laptop PC) and other products with touch function. Among the above electronic products, the original display function and the touch sensing function are mainly integrated to form a touch display device. At present, the technology development of touch panels is very diverse, and the more common technologies include resistive, capacitive, and optical. In a conventional resistive or capacitive touch panel, the sensing electrodes for performing touch detection are generally formed of a transparent conductive material such as indium tin oxide (ITO) in order to avoid affecting the display effect. Since the resistivity of the transparent conductive material is generally higher than that of the metal conductive material, the use of the transparent conductive material to form the sensing electrode may cause an overall high resistance value and affect the reaction speed. Therefore, in the related art, a metal mesh configured by a metal line has been developed to replace the transparent conductive material to form an electrode to improve the reaction speed. However, the general metal mesh pattern is repeatedly spliced by regular patterns such as regular hexagons or squares, so when such metal mesh patterns are matched with the display panel, if the side lengths of the metal meshes are When the pixel sizes in the display panel are similar, the Moiré effect is likely to occur and the overall display quality is affected.

本發明之主要目的之一在於提供一種觸控面板，利用不同形狀之三角形網格單元形成觸控電極，以改善觸控面板與顯示畫素搭配時發生疊紋(Moiré)效應之不良影響。 One of the main purposes of the present invention is to provide a touch panel that utilizes different shapes. The triangular grid unit forms a touch electrode to improve the adverse effect of the moiré effect when the touch panel is matched with the display pixel.

為達上述目的，本發明之一較佳實施例提供一種觸控面板，包括一觸控電極，且觸控電極包括複數個三角形網格單元。三角形網格單元係互相拼接設置，且各三角形網格單元係與至少一相鄰之三角形網格單元具有不同的形狀。各三角形網格單元具有三個側邊彼此相連，且各三角形網格單元之至少兩該等側邊的長度相異。 To achieve the above objective, a preferred embodiment of the present invention provides a touch panel including a touch electrode, and the touch electrode includes a plurality of triangular mesh units. The triangular mesh units are spliced to each other, and each triangular mesh unit has a different shape from at least one adjacent triangular mesh unit. Each of the triangular mesh units has three sides connected to each other, and at least two of the sides of each of the triangular mesh units have different lengths.

本發明之觸控面板係利用形狀不同之非等邊三角形網格單元形成觸控電極，藉由此形狀不同之非等邊三角形網格單元互相拼接排列設置，可改善觸控面板與顯示畫素搭配時發生疊紋效應之不良影響，進而達到改善整體視效之目的。 The touch panel of the present invention forms a touch electrode by using non-equilateral triangular mesh units with different shapes, and the non-equilateral triangular mesh units with different shapes are arranged and arranged one another, thereby improving the touch panel and the display pixel. The adverse effect of the moiré effect occurs when collocation, thereby achieving the goal of improving overall visual effects.

請參考第1圖至第3圖。第1圖至第3圖繪示了本發明之一較佳實施例的觸控面板之網格的形成方法的示意圖。其中第1圖為一流程示意圖。為了方便說明，本發明之各圖式僅為示意以更容易了解本發明，其詳細的比例可依照設計的需求進行調整。如第1圖至第3圖所示，本發明之一較佳實施例提供一種觸控面板之網格的形成方法，此方法包括下列步驟。首先，進行步驟S110，提供一第一三角形網格圖案單元P1，第一三角形網格圖案單元P1具有三個第一側邊E1彼此相連，且至少兩第一側邊E1的長度相異。第一三角形網格圖案單元P1係為一非等邊三角形，且第一三角形網格圖案單元P1之三個第一側邊E1較佳係彼此不相等，但本發明並不以此為限，在本發明之其他較佳實施例中亦可使用僅兩個第一側邊E1長度相異之等腰三角形當作第一三角形網格圖案單元P1。換句話說，第一三角形網格圖案單元P1不包括正三角形。此外，第一三角形網格圖案單元P1中至少兩第一側邊E1的長度相差範圍較佳係大於其中較短之第一側邊E1之長度的5%，但並不以此為限。 Please refer to Figures 1 to 3. 1 to 3 are schematic views showing a method of forming a grid of a touch panel according to a preferred embodiment of the present invention. The first picture is a schematic diagram of the process. For the convenience of description, the drawings of the present invention are only for the purpose of understanding the present invention, and the detailed proportions thereof can be adjusted according to the design requirements. As shown in FIG. 1 to FIG. 3, a preferred embodiment of the present invention provides a method for forming a grid of a touch panel, the method comprising the following steps. First, in step S110, a first triangular mesh pattern unit P1 is provided. The first triangular mesh pattern unit P1 has three first side edges E1 connected to each other, and at least two first side edges E1 have different lengths. The first triangular mesh pattern unit P1 is a non-equilateral triangle, and the three first side edges E1 of the first triangular mesh pattern unit P1 are preferably not equal to each other, but the invention is not limited thereto. In other preferred embodiments of the present invention, an isosceles triangle having only two first side edges E1 having different lengths may be used as the first triangular mesh pattern unit P1. In other words, the first triangular mesh pattern unit P1 does not include an equilateral triangle. In addition, the length difference between the at least two first side edges E1 of the first triangular mesh pattern unit P1 is preferably greater than 5% of the length of the shorter first side edge E1, but is not limited thereto.

接著，如第1圖與第2圖所示，進行步驟S120，以第一側邊E1為基礎自第一三角形網格圖案單元P1向外繪製複數個第二三角形網格圖案單元P2，其中各第一側邊E1係為各第二三角形網格圖案單元P2之一側邊 E2，且第一三角形網格圖案單元P1係與至少一第二三角形網格圖案單元P2具有不同的形狀。換句話說，第一三角形網格圖案單元P1係與其相接之第二三角形網格圖案單元P2共用一側邊，而此側邊係同時為第一三角形網格圖案單元P1之第一側邊E1與第二三角形網格圖案單元P2之側邊E2。此外，本實施例之各第二三角形網格圖案單元P2較佳係彼此形狀不同，且各第二三角形網格圖案單元P2亦與第一三角形網格圖案單元P1的形狀相異。在本實施例中，各第二三角形網格圖案單元P2亦分別為一非等邊三角形，也就是說各第二三角形網格圖案單元P2中至少兩側邊E2的長度相異，且各第二三角形網格圖案單元P2中之三個側邊E2長度較佳係彼此相異，但並不以此為限。此外，第一三角形網格圖案單元P1之開口面積係與至少一第二三角形網格圖案單元P2的開口面積相異，且第一三角形網格圖案單元P1與至少一第二三角形網格圖案單元P2的開口面積相差百分比範圍較佳係大於其中較小之第一三角形網格圖案單元P1或第二三角形網格圖案單元P2之開口面積的5%。換句話說，在此網格圖案中，第一三角形網格圖案單元P1與各第二三角形網格圖案單元P2較佳係彼此形狀相異。 Next, as shown in FIG. 1 and FIG. 2, step S120 is performed to draw a plurality of second triangular grid pattern units P2 from the first triangular grid pattern unit P1 on the basis of the first side E1, wherein each The first side E1 is a side of each of the second triangular grid pattern units P2 E2, and the first triangular mesh pattern unit P1 has a different shape from the at least one second triangular mesh pattern unit P2. In other words, the first triangular mesh pattern unit P1 shares a side with the second triangular mesh pattern unit P2 that is in contact with it, and the side is simultaneously the first side of the first triangular mesh pattern unit P1. E1 and a side E2 of the second triangular mesh pattern unit P2. In addition, each of the second triangular grid pattern units P2 of the present embodiment preferably has different shapes from each other, and each of the second triangular grid pattern units P2 is also different from the shape of the first triangular grid pattern unit P1. In this embodiment, each of the second triangular mesh pattern units P2 is also a non-equilateral triangle, that is, the lengths of at least two sides E2 of each second triangular grid pattern unit P2 are different, and each The lengths of the three side edges E2 in the two triangular mesh pattern units P2 are preferably different from each other, but are not limited thereto. In addition, the opening area of the first triangular mesh pattern unit P1 is different from the opening area of the at least one second triangular mesh pattern unit P2, and the first triangular mesh pattern unit P1 and the at least one second triangular mesh pattern unit The opening area percentage difference range of P2 is preferably larger than 5% of the opening area of the smaller first triangular mesh pattern unit P1 or the second triangular grid pattern unit P2. In other words, in this mesh pattern, the first triangular mesh pattern unit P1 and each of the second triangular mesh pattern units P2 are preferably different in shape from each other.

然後，如第1圖與第2圖所示，進行步驟S130，以第二三角形網格圖案單元P2之至少部分之側邊E2為基礎繪製複數個第三三角形網格圖案單元P3。至少部分之第二三角形網格圖案單元P2之側邊E2係為第三三角形網格圖案單元P3之側邊E3，且至少一第三三角形網格圖案單元P3係與至少一第二三角形網格圖案單元P2具有不同的形狀。換句話說，第二三角形網格圖案單元P2係與其相接之第三三角形網格圖案單元P3共用一側邊，而此側邊係同時為第二三角形網格圖案單元P2之側邊E2與第三三角形網格圖案單元P3之側邊E3。在本實施例中，各第三三角形網格圖案單元P3亦分別為一非等邊三角形，也就是說各第三三角形網格圖案單元P3中至少兩側邊E3的長度相異，且各第三三角形網格圖案單元P3中之三個側邊E3長度較佳係彼此相異，但並不以此為限。藉由重複進行類似上述步驟S120以及步驟S130的方式，可形成一如第2圖中所示之網格圖案PX。換句話說，網格圖案PX係由上述之非等邊三角形網格圖案單元所構成。利用網格圖案PX，例如將網格圖案PX製成光罩(圖未示)，用以對一導電材料層例如金屬層(圖未示)進行圖案化製程，即可如第3圖所示於一第一基板111上形成一觸控面板100之網格120M。因此，於步驟S140中，本發明係將第一三角形網格圖案單元P1、第二三角形網格圖案單元P2將第三三角形網格圖案單元P3轉換成網格120M。本發明之觸控面板的網格120M較佳可為金屬網格或由其他適合之導電材料所形成。上述之金屬層可包括金屬材料例如鋁、銅、銀、鉻、鈦、鉬之其中至少一者、上述材料之複合層或上述材料之合金，但並不以此為限上述之導電材料可包括導電粒子、奈米碳管或奈米銀絲，但並不以此為限。網格120M係由複數個三角形網格單元120P所構成。此外，三角形網格單元120P較佳係為金屬網格單元，但並不以此為限。換句話說，各三角形網格單元120P可包括鋁、銅、銀、鉻、鈦、鉬之其中至少一者、上述材料之複合層(例如由ITO/Ag/ITO或Mo/Al/Mo三層所堆疊成的複合層)、上述材料之合金、導電粒子、奈米碳管、奈米銀絲或其他適合之導電材料。各三角形網格單元120P係與網格圖案PX中的一個三角形網格圖案單元圖形相符。換句話說，網格120M的圖形可視需要與網格圖案PX中至少部分區域的圖形相符。因此，網格120M可為僅利用第一三角形網格圖案單元P1以及第二三角形網格圖案單元P2所形成，換句話說即是可於步驟S120後直接將第一三角形網格圖案單元P1以及第二三角形網格圖案單元P2轉換成網格120M。或者，網格120M亦可為利用第一三角形網格圖案單元P1、第二三角形網格圖案單元P2、第三三角形網格圖案單元P3以及其他延伸形成之多邊形三角形網格圖案單元所形成。 Then, as shown in FIGS. 1 and 2, step S130 is performed to draw a plurality of third triangular grid pattern units P3 based on at least a portion of the side E2 of the second triangular grid pattern unit P2. At least a portion of the side E2 of the second triangular grid pattern unit P2 is a side E3 of the third triangular grid pattern unit P3, and at least a third triangular grid pattern unit P3 is coupled to at least a second triangular grid. The pattern unit P2 has a different shape. In other words, the second triangular mesh pattern unit P2 shares a side with the third triangular mesh pattern unit P3 that is in contact with it, and the side is simultaneously the side E2 of the second triangular mesh pattern unit P2 and The side edge E3 of the third triangular mesh pattern unit P3. In this embodiment, each of the third triangular mesh pattern units P3 is also a non-equilateral triangle, that is, the lengths of at least two sides E3 of each third triangular grid pattern unit P3 are different, and each The three sides E3 of the three triangular mesh pattern unit P3 preferably have a length This is different, but not limited to this. By repeating the manner similar to the above-described steps S120 and S130, a mesh pattern PX as shown in Fig. 2 can be formed. In other words, the mesh pattern PX is composed of the above-described non-equilateral triangular mesh pattern unit. Using the mesh pattern PX, for example, the mesh pattern PX is formed into a photomask (not shown) for patterning a conductive material layer such as a metal layer (not shown), as shown in FIG. A grid 120M of the touch panel 100 is formed on a first substrate 111. Therefore, in step S140, the present invention converts the third triangular mesh pattern unit P1 into the mesh 120M by the first triangular mesh pattern unit P1 and the second triangular mesh pattern unit P2. The mesh 120M of the touch panel of the present invention may preferably be a metal mesh or formed of other suitable conductive materials. The metal layer may include at least one of a metal material such as aluminum, copper, silver, chromium, titanium, molybdenum, a composite layer of the above materials or an alloy of the above materials, but not limited thereto, the conductive material may include Conductive particles, carbon nanotubes or nano-silver, but not limited to this. The mesh 120M is composed of a plurality of triangular mesh units 120P. In addition, the triangular mesh unit 120P is preferably a metal mesh unit, but is not limited thereto. In other words, each triangular grid unit 120P may include at least one of aluminum, copper, silver, chromium, titanium, molybdenum, a composite layer of the above materials (for example, ITO/Ag/ITO or Mo/Al/Mo The stacked composite layer), the alloy of the above materials, conductive particles, carbon nanotubes, nanosilver or other suitable electrically conductive material. Each of the triangular mesh units 120P is in conformity with one of the triangular mesh pattern unit patterns in the mesh pattern PX. In other words, the graphics of the mesh 120M can be visually matched to the graphics of at least a portion of the mesh pattern PX. Therefore, the mesh 120M may be formed by using only the first triangular mesh pattern unit P1 and the second triangular mesh pattern unit P2, in other words, the first triangular mesh pattern unit P1 and the first triangular mesh pattern unit P1 may be directly after step S120. The second triangular mesh pattern unit P2 is converted into a mesh 120M. Alternatively, the mesh 120M may be formed by using the first triangular mesh pattern unit P1, the second triangular mesh pattern unit P2, the third triangular mesh pattern unit P3, and other extended polygonal triangular grid pattern units.

在本實施例中，第一三角形網格圖案單元P1之第一側邊E1以及第二三角形網格圖案單元P2之側邊E2的長度具有一長度平均值以及一長度標準差△L。長度平均值的定義如下： In this embodiment, the length of the first side E1 of the first triangular mesh pattern unit P1 and the side E2 of the second triangular mesh pattern unit P2 have a length average value. And a length standard deviation ΔL. Average length The definition is as follows:

長度標準差△L定義如下： The length standard deviation ΔL is defined as follows:

方程式(1)與(2)中，L _i代表網格中某一個非等邊三角型其中一個邊的邊長(例如在第2圖中，第一三角形網格圖案單元P1三個邊長分別為L ₁ 、L ₂ 、L ₃)，N代表所選取的網格120M中所有非等邊三角型邊的總數。 In equations (1) and (2), L _i represents the side length of one of the sides of a non-equal triangle in the grid (for example, in FIG. 2, the three sides of the first triangular grid pattern unit P1 are respectively For L ₁ , L ₂ , L ₃ ), N represents the total number of all non-equilateral triangular sides in the selected mesh 120M.

In addition, the length of the first side E1 of the first triangular mesh pattern unit P1, the side E2 of the second triangular mesh pattern unit P2, and the side E3 of the third triangular mesh pattern unit P3 may also have the above length. average value And the standard deviation of length ΔL, but not limited to this.

為了更進一步說明本發明之三角形網格單元的優點，請參考第12圖與第13圖。第12圖繪示了本發明之一較佳實施例之以網格形成之走線的結構示意圖。第13圖繪示了以非三角形網格單元的多邊形網格形成之走線的結構示意圖。如第12圖所示，本發明之網格120M可藉由適當的斷線形成與連接墊180相連之走線120W。相對地，如第13圖所示，若以一多邊形網格920M進行適當的斷線以形成與連接墊180相連之走線920W，則走線920會因為所需之彎折幅度較大而造成對電阻抗的負面影響。因此，以本發明之由非等邊三角形網格單元構成之網格120M所形成之走線120W整體來說可較趨近於一直線，故可達到降低走線阻抗的效果。 In order to further illustrate the advantages of the triangular mesh unit of the present invention, please refer to Figures 12 and 13. Figure 12 is a block diagram showing the structure of a trace formed by a grid in accordance with a preferred embodiment of the present invention. Figure 13 is a schematic view showing the structure of a trace formed by a polygonal mesh of non-triangular mesh cells. As shown in Fig. 12, the mesh 120M of the present invention can form a trace 120W connected to the connection pad 180 by a suitable broken line. In contrast, as shown in FIG. 13, if a polygonal mesh 920M is appropriately broken to form a trace 920W connected to the connection pad 180, the trace 920 may be caused by a large bending margin. Negative effects on electrical impedance. Therefore, the trace 120W formed by the mesh 120M composed of the non-equilateral triangular mesh unit of the present invention can be closer to the straight line as a whole, so that the effect of reducing the trace impedance can be achieved.

綜合以上所述，本發明之觸控面板係利用不規則之非等邊三角形網格單元形成觸控電極，藉由此不規則之三角形網格單元互相拼接排列設置，可改善觸控面板與顯示面板中的顯示畫素搭配時發生疊紋效應之不良影響，進而達到改善整體視效之目的。此外，本發明亦提供觸控面板之網格的形成方法，藉由此方法來形成具有不規則之三角形網格單元的觸控面板。此外，本發明之以非等邊三角形網格單元構成之網格亦可用於形成整體電阻抗較低之走線，藉此提升觸控面板之電性表現。 In summary, the touch panel of the present invention forms an touch electrode by using an irregular non-equilateral triangular grid unit, and the irregular triangular grid unit is arranged in a splicing manner to improve the touch panel and display. The adverse effect of the moiré effect occurs when the pixels in the panel are displayed, thereby achieving the overall visual effect. In addition, the present invention also provides a method for forming a grid of a touch panel, by which a touch panel having irregular triangular grid cells is formed.
