台灣第M476982號新型專利係揭露一種觸控面板，其係揭露電極配置於基板上，但因為電極與基板通常是不同的材質，因此，若基板的表面沒有經過特殊處理時，電極通常無法穩固地配置在基板上。再者，使用電極墊容易讓線路輪廓容易被肉眼發現，雖然，該專利揭露利用改變電極墊的外圍輪廓線條來降低電極的可視性及光吸收層來降低電極的反射率，但改變電極墊的外圍輪廓不僅增加製造成本，也會提高製程的複雜性，又增加光吸收層也會增加成本，及增加觸控面板的厚度。The new patent No. M476982 discloses a touch panel in which the electrode is disposed on the substrate. However, since the electrode and the substrate are usually made of different materials, if the surface of the substrate is not specially treated, the electrode is generally not stable. Configured on the substrate. Furthermore, the use of electrode pads tends to make the line outlines easily visible to the naked eye, although the patent discloses that by changing the peripheral contour lines of the electrode pads to reduce the visibility of the electrodes and the light absorbing layer to reduce the reflectivity of the electrodes, the electrode pads are changed. The peripheral profile not only increases the manufacturing cost, but also increases the complexity of the process. Increasing the light absorbing layer also increases the cost and increases the thickness of the touch panel.
台灣第M476311號新型專利係揭露一種觸控面板，其係藉由在頂部電極的上方設置抗反射層，並在頂部電極的底部設置虛擬電極，如此來讓頂部電極層的圖案變成不可視，但這種方式會增加製造成本，且會提高製造的複雜性。Taiwan Patent No. M476311 discloses a touch panel which is provided with an anti-reflection layer above the top electrode and a dummy electrode at the bottom of the top electrode, so that the pattern of the top electrode layer becomes invisible, but This approach increases manufacturing costs and increases manufacturing complexity.

較佳地，該些第一導電路徑的第一金屬導體層的表面顏色係深色的，且其導電率係優於該些第一導電漿料層的導電率。如此，第一金屬導體層係可藉由深色的外表顏色降低應用在觸控裝置中的肉眼可視性。Preferably, the surface color of the first metal conductor layer of the first conductive paths is dark, and the conductivity is superior to the conductivity of the first conductive paste layers. As such, the first metal conductor layer can reduce macroscopic visibility applied to the touch device by the dark appearance color.
較佳地，觸控元件更包括一第二感應電極層。第二感應電極層係形成於透明基層上，且與第一感應電極層之間係絕緣的，並具有多個第二導電路徑。每一第二導電路徑具有一第二導電漿料層及一第二金屬導體層。第二導電漿料層係連接透明基層，第二金屬導體層係連接第二導電漿料層，且位在第二導電漿料層的表面。Preferably, the touch element further comprises a second sensing electrode layer.

以下，茲配合各圖式列舉對應之較佳實施例來對本創作的觸控裝置及其觸控元件的組成構件及達成功效來作說明。然各圖式中觸控裝置及 其觸控元件的構件、尺寸及外觀僅用來說明本創作的技術特徵，而非對本創作構成限制。Hereinafter, the preferred embodiment of the present invention will be described with reference to the preferred embodiments to describe the components of the touch device and its touch elements and the achievement of the functions. However, the touch devices in each figure and The components, dimensions and appearance of the touch elements are only used to illustrate the technical features of the creation, and are not intended to limit the creation.
如第1圖所示，本創作的觸控元件10包括一透明基層11及一第一感應電極層13。透明基層11的材質較佳係選用玻璃、壓克力或樹脂等製成的薄膜或板材。第一感應電極層13是形成於透明基層11上，其中，形成的方式請容後在述。As shown in FIG. 1 , the touch element 10 of the present invention comprises a transparent base layer 11 and a first sensing electrode layer 13 . The material of the transparent base layer 11 is preferably a film or sheet made of glass, acrylic or resin. The first sensing electrode layer 13 is formed on the transparent base layer 11, and the manner of formation thereof will be described later.
第一感應電極層13具有多個第一導電路徑131。於此實施例中，該些第一導電路徑131係分別以菱形連接的網格圖案為例，但實際上，第一導電路徑131也可以是其他多邊形的形狀，所以不以菱形圖案為限。The first sensing electrode layer 13 has a plurality of first conductive paths 131. In this embodiment, the first conductive paths 131 are respectively exemplified by a diamond-connected mesh pattern. However, the first conductive paths 131 may be other polygonal shapes, and thus are not limited to the diamond pattern.
如第2圖所示，每一第一導電路徑131具有一第一導電漿料層133及一第一金屬導體層135，第一導電漿料層133是連接透明基層11。第一金屬導體層135是連接第一導電漿料層133，且位在第一導電漿料層133的表面。As shown in FIG. 2, each of the first conductive paths 131 has a first conductive paste layer 133 and a first metal conductor layer 135, and the first conductive paste layer 133 is connected to the transparent base layer 11. The first metal conductor layer 135 is connected to the first conductive paste layer 133 and is located on the surface of the first conductive paste layer 133.
第一導電漿料層133較佳係選用銀漿、金漿、鋁漿、碳漿及鎳漿，或者選用銀漿、金漿、鋁漿、碳漿及鎳漿的混合漿料，其中，混合漿料係指混合有至少兩種前述漿料。The first conductive paste layer 133 is preferably selected from the group consisting of silver paste, gold paste, aluminum paste, carbon paste and nickel paste, or a mixed slurry of silver paste, gold paste, aluminum paste, carbon paste and nickel paste, wherein, the mixture is mixed. Slurry refers to a mixture of at least two of the foregoing slurries.
由於，導電漿料係由括金屬粒及黏合劑等材料混合而成的黏稠液體，因此，導電漿料本身係可以藉由金屬粒彼此相連來達到導電的效果，但如果導電漿料的金屬粒混合或分佈不均，致使有部分金屬粒沒有接觸時，導電漿料的導電效果將會變差。為了改善導電率不佳的問題，本創作係藉由第一導電漿料層133上電鍍第一金屬導體層135，第一金屬導體層135的導電率是優於第一導電漿料層133的導電率，以使導電路徑131具有良好的導電率。由於本創作的觸控元件有第一導電漿料層133，因此，在電鍍過程中，第一金 屬導體層135係可順利地依附在第一導電漿料層133上，第一金屬導體層135的材料較佳係選用銅、銀及金等導電材料。其中，於此實施例中，金屬粒可以是各種尺寸，所以，本創作係不限制金屬粒的尺寸。Since the conductive paste is a viscous liquid which is formed by mixing materials such as metal particles and a binder, the conductive paste itself can be electrically connected by being connected to each other by metal particles, but if the conductive paste is metal particles If the mixing or distribution is uneven, the conductive effect of the conductive paste will be deteriorated when some of the metal particles are not in contact. In order to improve the problem of poor conductivity, the present invention performs electroplating of the first metal conductor layer 135 on the first conductive paste layer 133, and the conductivity of the first metal conductor layer 135 is superior to that of the first conductive paste layer 133. Conductivity so that the conductive path 131 has good electrical conductivity. Since the touch element of the present invention has the first conductive paste layer 133, in the electroplating process, the first gold The conductor layer 135 can be smoothly attached to the first conductive paste layer 133. The material of the first metal conductor layer 135 is preferably a conductive material such as copper, silver or gold. Herein, in this embodiment, the metal particles may be of various sizes, and therefore, the present invention does not limit the size of the metal particles.
於此實施例中，觸控元件10係藉由壓印設備對透明基層11表面形成對應該些第一導電路徑131的圖案的凹槽，之後塗佈導電漿料於凹槽內，並移除多餘的導電漿料，而形成第一導電漿料層133，最終，利用電極電鍍或無電極電鍍來進行電鍍，以使電鍍液中的金屬離子被吸附在第一導電漿料層133的表面，而形成第一金屬導體層135。In this embodiment, the touch element 10 forms a groove corresponding to the pattern of the first conductive paths 131 on the surface of the transparent base layer 11 by the imprinting device, and then applies the conductive paste in the groove and removes Excess conductive paste to form the first conductive paste layer 133, and finally, electroplating is performed by electrode plating or electroless plating so that metal ions in the plating solution are adsorbed on the surface of the first conductive paste layer 133. The first metal conductor layer 135 is formed.
其中，觸控元件10也可以採用轉印製程來將第一導電漿料層133轉印至透明基層11上，故該些第一導電路徑131的第一導電漿料層133的形成方式係不以上述壓印方式為限，且透明基層11可不以有凹槽為限。如此，本創作的觸控元件10只要控制第一導電漿料層133的線寬，就可以控制第一導電路徑131線寬。The touch element 10 can also transfer the first conductive paste layer 133 to the transparent base layer 11 by using a transfer process. Therefore, the first conductive paste layer 133 of the first conductive paths 131 is formed in a manner other than The above-mentioned imprinting method is limited, and the transparent base layer 11 may not be limited to the groove. As such, the touch element 10 of the present invention can control the line width of the first conductive path 131 as long as the line width of the first conductive paste layer 133 is controlled.
此外，該些第一導電路徑131的第一金屬導體層135的顏色是深色，例如黑色，這樣可避免第一金屬導體層135反射可見光，來降低該些第一導電路徑131的可視性。其中第一金屬導體層135的表面顏色處理係可藉由在第一金屬導體層135的表面電鍍鎳或鉬等深色金屬或合金，並讓電鍍後的深色金屬或合金表面氧化，來使第一金屬導體層135的表面顏色變黑。或者，塗佈深色塗料於第一金屬導體層135的表面，使第一金屬導體層135的表面不會發生反射現象。因此，第一金屬導體層135的表面顏色處理係不以上述兩個方式為限。In addition, the color of the first metal conductor layer 135 of the first conductive paths 131 is dark, such as black, so that the first metal conductor layer 135 can be prevented from reflecting visible light to reduce the visibility of the first conductive paths 131. The surface color treatment of the first metal conductor layer 135 can be performed by plating a dark metal or alloy such as nickel or molybdenum on the surface of the first metal conductor layer 135 and oxidizing the surface of the dark metal or alloy after plating. The surface color of the first metal conductor layer 135 becomes black. Alternatively, a dark paint is applied to the surface of the first metal conductor layer 135 so that the surface of the first metal conductor layer 135 does not reflect. Therefore, the surface color treatment of the first metal conductor layer 135 is not limited to the above two modes.
本創作的觸控元件除了上述的單層感應電極層外，本創作的觸控元件也可以是雙層的感應電極層，隨後詳述雙層感應電極層的結構。In addition to the above-mentioned single-layer sensing electrode layer, the touch element of the present invention may also be a double-layered sensing electrode layer, and then the structure of the double-layered sensing electrode layer will be described in detail.
如第3、4及5圖所示，第4及5圖分別係本創作的觸控元件20的第二及第三實施例的示意圖，由於第二及第三實施例的觸控元件20的上視圖是相同的，因此都以第3圖為例。觸控元件20包括一透明基層21、一第一感應電極層23及一第二感應電極層25。第一及第二感應電極層23、25係分別形成於透明基層21上，且相互之間是絕緣的關係。第一感應電極層23具有多個第一導電路徑231，每一第一導電路徑231具有一第一導電漿料層233及一第一金屬導體層235，其中，第一感應電極層23的結構、組成、材質、製程及目的係與前一實施例相同，故於此不再贅述。第二感應電極層25具有多個第二導電路徑251，每一第二導電路徑251具有一第二導電漿料層253及一第二金屬導體層255。第二導電漿料層253係連接透明基層21。第二金屬導體層255係連接第二導電漿料層253，且位在第二導電漿料層253的表面，並其導電率係優於第二導電漿料層253。As shown in Figures 3, 4 and 5, Figures 4 and 5 are schematic views of the second and third embodiments of the touch element 20 of the present invention, respectively, due to the touch elements 20 of the second and third embodiments. The top view is the same, so let's take Figure 3 as an example. The touch component 20 includes a transparent substrate 21, a first sensing electrode layer 23, and a second sensing electrode layer 25. The first and second sensing electrode layers 23, 25 are formed on the transparent base layer 21, respectively, and are insulated from each other. The first sensing electrode layer 23 has a plurality of first conductive paths 231, each of the first conductive paths 231 has a first conductive paste layer 233 and a first metal conductor layer 235, wherein the structure of the first sensing electrode layer 23 The composition, the material, the process, and the purpose are the same as those in the previous embodiment, and thus will not be described again. The second sensing electrode layer 25 has a plurality of second conductive paths 251 , and each of the second conductive paths 251 has a second conductive paste layer 253 and a second metal conductor layer 255 . The second conductive paste layer 253 is connected to the transparent base layer 21. The second metal conductor layer 255 is connected to the second conductive paste layer 253 and is located on the surface of the second conductive paste layer 253 and has a conductivity superior to that of the second conductive paste layer 253.
該些第二導電路徑251係與該些第一導電路徑231的結構、組成、材質、顏色、製程及目的都相同，所以相同的部分不再贅述。The second conductive paths 251 are the same as the structures, compositions, materials, colors, processes, and purposes of the first conductive paths 231, so the same portions will not be described again.
在第4圖中，該些第一導電路徑231的第一金屬導體層235及該些第二導電路徑251的第二金屬導體層255係朝向相同方向。這個結構中，觸控元件20係先藉由壓印或轉印設備將第一感應電極層23製作於透明基層21上後，再藉由樹脂堆疊在透明基層21上，並利用壓印設備壓印樹脂來形成對應該些第二導電路徑251的圖案的凹槽，最終，於凹槽中塗佈導電漿料並對固化的導電漿料電鍍來形成第二導電漿料層253及第二金屬導體層255。由於樹脂固化後的光學特性係與透明基層的光學特性相近，因此，固化後的樹脂係不會影響觸控元件20的光學特性，且能使第一及第二導電路徑231、251之間形成絕緣。In FIG. 4, the first metal conductor layer 235 of the first conductive path 231 and the second metal conductor layer 255 of the second conductive paths 251 are oriented in the same direction. In this structure, the touch element 20 is first formed on the transparent substrate 21 by an imprint or transfer device, and then stacked on the transparent substrate 21 by a resin, and pressed by an imprint apparatus. Printing a resin to form a groove corresponding to the pattern of the second conductive paths 251, and finally, coating the conductive paste in the groove and plating the solidified conductive paste to form the second conductive paste layer 253 and the second metal Conductor layer 255. Since the optical characteristics after curing of the resin are similar to those of the transparent substrate, the cured resin does not affect the optical characteristics of the touch element 20, and can form between the first and second conductive paths 231, 251. insulation.
除了藉由上述的方式製造第二感應電極層外，觸控元件也可以是兩個第一實施例的觸控元件相互堆疊的結構。In addition to manufacturing the second sensing electrode layer by the above method, the touch element may also be a structure in which the touch elements of the two first embodiments are stacked on each other.
在第5圖中，該些第一導電路徑231的第一金屬導體層235及該些第二導電路徑251的第二金屬導體層255係朝相反方向。這個結構中，觸控元件20的透明基層21係先以壓印設備製作出兩面都有凹槽的結構，或是藉由壓印設備於透明基層21的兩面貼附對應的第一及第二導電漿料層233、253，之後在塗佈導電漿料及電鍍，來形成第一及第二導電路徑231、251。In FIG. 5, the first metal conductor layer 235 of the first conductive path 231 and the second metal conductor layer 255 of the second conductive paths 251 are in opposite directions. In this structure, the transparent base layer 21 of the touch element 20 is firstly formed with a groove on both sides by an imprinting apparatus, or the corresponding first and second are attached to both sides of the transparent base layer 21 by an imprint apparatus. The conductive paste layers 233 and 253 are then coated with a conductive paste and plated to form first and second conductive paths 231 and 251.
如此，本創作的觸控元件係藉由配置在透明基板上的第一及第二導電漿料層來讓第一及第二金屬導體層得以藉由電鍍附著，及降低製造成本。再者，觸控裝置應用本創作的觸控元件是可以降低觸控元件的感應電極層的導電路徑可視性。Thus, the touch element of the present invention allows the first and second metal conductor layers to be adhered by electroplating by the first and second conductive paste layers disposed on the transparent substrate, and the manufacturing cost is reduced. Furthermore, the touch device uses the touch element of the present invention to reduce the visibility of the conductive path of the sensing electrode layer of the touch element.
如第6圖所示，前述的觸控元件係應用於觸控裝置上，隨後以內嵌式(In-cell)觸控裝置為例來說明。觸控裝置40包括一顯示面板(LCD cell)41、一觸控元件43及兩偏光片(Polarizer)45、47。其中，顯示面板包括TFT陣列(array)基板等，而觸控元件43可以是被製作在彩色濾光片(color filter)的表面，這樣，彩色濾光片就是前述的透明基板，觸控元件請參照前述第二或第三實施例所述的觸控元件，故不再贅述觸控元件的組成及結構。觸控元件係連接顯示面板。顯示面板41及觸控元件43係位在兩偏光片45、47之間。如此，外部光線通過偏光片，且射向觸控元件43的第一及第二導電路徑的第一及第二金屬導體層431、433是不會產生反射，因此，人眼就不易從觸控裝置40的外觀觀察到第一及第二感應電極層431、433的圖案。As shown in FIG. 6, the touch element described above is applied to a touch device, and then an in-cell touch device is taken as an example for illustration. The touch device 40 includes a display panel (LCD cell) 41, a touch element 43 and two polarizers 45, 47. The display panel includes a TFT array substrate, and the touch element 43 may be formed on a surface of a color filter. Thus, the color filter is the transparent substrate, and the touch component is required. Referring to the touch element described in the second or third embodiment, the composition and structure of the touch element will not be described again. The touch element is connected to the display panel. The display panel 41 and the touch element 43 are positioned between the two polarizers 45 and 47. In this way, the external light passes through the polarizer, and the first and second metal conductor layers 431 and 433 that are incident on the first and second conductive paths of the touch element 43 are not reflected, so that the human eye is not easily touched. The appearance of the device 40 observes the patterns of the first and second sensing electrode layers 431, 433.
此外，本創作的觸控裝置也可以在彩色濾光片上製作第一實施例的觸控元件，即單層感應電極層，並在彩色濾光片上堆疊另一單層感應電極層的觸控元件，如此，也可以形成雙層感應電極層的結構。或者，藉由樹脂於彩色濾光片上形成本創作的觸控元件的透明基層，並在固化後的樹脂上製作第一及第二感應電極層。In addition, the touch device of the present invention can also fabricate the touch element of the first embodiment on the color filter, that is, the single-layer sensing electrode layer, and stack the touch of another single-layer sensing electrode layer on the color filter. Thus, the structure of the double-layered sensing electrode layer can also be formed. Alternatively, a transparent base layer of the touch element of the present invention is formed on the color filter by a resin, and the first and second sensing electrode layers are formed on the cured resin.
雖然，觸控裝置係以內嵌式為例來說明，但實際上，本創作的觸控元件也可以應用於外掛式(On-cell)或外加式(Out-cell)的觸控裝置結構中，故不以內嵌式為限。Although the touch device is illustrated by an in-line type, in reality, the touch element of the present invention can also be applied to an on-cell or out-cell touch device structure. Therefore, it is not limited to the embedded type.
再者，本創作的觸控元件的感應電極層係直接將金屬導體層作黑化處理，而不需要電極墊、改變電極墊的外輪廓圖案及增加光吸收層，故可減化製程及其結構，並降低製造成本。Furthermore, the sensing electrode layer of the touch element of the present invention directly blackens the metal conductor layer without the need for an electrode pad, changing the outer contour pattern of the electrode pad, and adding a light absorbing layer, thereby reducing the process and Structure and reduce manufacturing costs.
最後，再次強調，本創作於前揭實施例中所揭露的構成元件，僅為舉例說明，並非用來限制本案之範圍，其他等效元件的替代或變化，亦應為本案之申請專利範圍所涵蓋。Finally, it is emphasized that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. The substitution or variation of other equivalent elements should also be the scope of the patent application of the present application. Covered.
