面板以及其製造方法與應用其之電子裝置Panel, and manufacturing method thereof and electronic device using same

本發明是有關於一種面板以及其製造方法與應用其之觸控顯示面板，且特別是有關於一種由多條線路構成成單一條傳輸線之面板以及其製造方法與應用其之觸控顯示面板。The present invention relates to a panel, a manufacturing method thereof, and a touch display panel using the same, and more particularly to a panel composed of a plurality of lines as a single transmission line, a manufacturing method thereof, and a touch display panel using the same.

觸控面板包括基板、感應線路及訊號傳輸線。感應線路及訊號傳輸線形成於基板上，感應線路可感應手指或觸控筆的觸控指令，訊號傳輸線則可傳送觸控指令至一電路板。為因應不同觸控面板的尺寸需求，訊號傳輸線的寬度也要配合變更。The touch panel includes a substrate, a sensing line, and a signal transmission line. The sensing line and the signal transmission line are formed on the substrate, the sensing line can sense the touch command of the finger or the stylus, and the signal transmission line can transmit the touch command to a circuit board. In order to meet the size requirements of different touch panels, the width of the signal transmission line should also be changed.

變更訊號傳輸線的寬度的設計過程中，需要重新設計網版上的鏤空圖案，然後配合訊號傳輸線的材料性質，在多次印刷驗證後，才能避免形成於鏤空圖案內的訊號傳輸線材料過度擴散而彼此接觸。也就是說，觸控面板必須避免相鄰二傳輸訊號線彼此接觸，因為相接觸之二訊號傳輸線將導致短路的不良問題。In the design process of changing the width of the signal transmission line, it is necessary to redesign the hollow pattern on the screen, and then with the material properties of the signal transmission line, after multiple printing verifications, the signal transmission line materials formed in the hollow pattern can be prevented from being excessively spread and mutually contact. That is to say, the touch panel must avoid the adjacent two transmission signal lines from contacting each other, because the two signal transmission lines that are in contact with each other will cause a short circuit problem.

然而，在驗證新訊號傳輸線寬度的過程相當耗時，一般來講需要2至3個月。對於產品生命短的觸控式電子裝置而言，如何縮短設計新訊號傳輸線的時程是本產業面臨的課題之一。However, the process of verifying the width of a new signal transmission line is quite time consuming and generally takes 2 to 3 months. For touch-sensitive electronic devices with short product life, how to shorten the time course for designing new signal transmission lines is one of the problems facing the industry.

此外，由於訊號傳輸線材料的流動性，使訊號傳輸線之邊緣形成邊緣凹、凸部。愈寬的訊號傳輸線，其邊緣凹、凸部的凹凸幅度愈大，導致相鄰二傳輸訊號線彼此接觸而短路的機率更大。In addition, due to the fluidity of the signal transmission line material, the edges of the signal transmission line form edge concaves and convex portions. The wider the signal transmission line, the larger the unevenness of the concave and convex portions of the edge, and the probability that the adjacent two transmission signal lines are in contact with each other and short-circuited is larger.

本發明係有關於一種面板以及其製造方法與應用其之觸控顯示面板，多條細的訊號線接觸而成為單條訊號傳輸線，使訊號傳輸線的邊緣凹、凸部甚小，如此相鄰二傳輸訊號線彼此接觸而短路的機率很小。The invention relates to a panel, a manufacturing method thereof and a touch display panel using the same, and a plurality of thin signal lines are in contact to form a single signal transmission line, so that the edge of the signal transmission line is concave and convex, so that the adjacent two transmissions The probability that the signal lines are in contact with each other and shorted is small.

Control panel or electromagnetic induction touch panel.

如第1圖所示，觸控面板100包括基板110、感應結構120及至少一訊號傳輸線130。感應結構120形成於基板110之可視區R1內。訊號傳輸線130連接於感應結構120並對應非可視區R2形成於基板110上，其中非可視區R2例如是基板110之邊緣區域。訊號傳輸線130包括第一訊號線131、第二訊號線132及第三訊號線133，第二訊號線132電性接觸於第一訊號線131，而第二訊號線132電性接觸於第三訊號線133。As shown in FIG. 1 , the touch panel 100 includes a substrate 110 , an inductive structure 120 , and at least one signal transmission line 130 . The sensing structure 120 is formed in the visible region R1 of the substrate 110. The signal transmission line 130 is connected to the sensing structure 120 and is formed on the substrate 110 corresponding to the non-visible area R2, wherein the non-visible area R2 is, for example, an edge area of the substrate 110. The signal transmission line 130 includes a first signal line 131, a second signal line 132, and a third signal line 133. The second signal line 132 is electrically connected to the first signal line 131, and the second signal line 132 is electrically connected to the third signal line. Line 133.

雖然本實施例之訊號傳輸線130以包括三條訊號線為例說明，然一實施例中，訊號傳輸線130也可以僅包括二條訊號線；或者，另一實施例中，訊號傳輸線130可包括四條或四條以上的訊號線。訊號傳輸線之訊號線的數量可由訊號傳輸線130的預設寬度而定，本發明實施例並不作限制。The signal transmission line 130 of the present embodiment is exemplified by three signal lines. In another embodiment, the signal transmission line 130 may include only two signal lines. Alternatively, in another embodiment, the signal transmission line 130 may include four or four lines. The above signal line. The number of the signal lines of the signal transmission line may be determined by the preset width of the signal transmission line 130, which is not limited in the embodiment of the present invention.

本實施例中，單條訊號傳輸線130係以多條細的訊號線組成，可使訊號傳輸線之邊緣凹、凸部甚小，如此，即始縮小相鄰二條訊號傳輸線130的間距，相鄰二傳輸訊號線彼此接觸而短路的機率也很小。此外，可使用既有訊號線寬度規格的網版，如此可在不需對網版進行大幅設計變更的情況下，形成訊號傳輸線130。In this embodiment, the single signal transmission line 130 is composed of a plurality of thin signal lines, so that the edge of the signal transmission line is concave and convex, so that the distance between the adjacent two signal transmission lines 130 is reduced, and the adjacent two transmissions are transmitted. The probability that the signal lines are in contact with each other and shorted is also small. In addition, a screen having an existing signal line width specification can be used, so that the signal transmission line 130 can be formed without major design changes to the screen.

如第1圖所示，感應結構120包括數條第一感應電極及數條第二感應電極。各第一感應電極形成於基板110之上表面110a(上表面110a繪示於第2圖)上且沿第一方向D1延伸，以感應觸控點沿第一方向D1的座標。各第一感應電極包括多個第一感應單元121及多條第一導電線123，相鄰二第一感應單元121由對應之第一導電線123連接。As shown in FIG. 1, the sensing structure 120 includes a plurality of first sensing electrodes and a plurality of second sensing electrodes.

Each of the first sensing electrodes includes a plurality of first sensing units 121 and a plurality of first conductive lines 123. The adjacent two first sensing units 121 are connected by corresponding first conductive lines 123.

如第1圖所示，各第二感應電極形成於基板110之上表面110a(上表面110a繪示於第2圖)上且沿第二方向D2延伸。各第二感應電極包括多個第二感應單元122及多條第二導電線124，相鄰二第二感應單元122由對應之第二導電線124連接。第一導電線123與第二導電線124係透過絕緣塊(未繪示)電性隔離。上述第一方向D1及第二方向D2係不同方向，例如，第一方向D1是X軸向，而第二方向D2是Y軸向。此外，第一感應單元121及第二感應單元122的材質例如是銦錫氧化物(Indium tin oxide,ITO)。第一導電線123及第二導電線124的材質例如是金屬。As shown in FIG. 1, each of the second sensing electrodes is formed on the upper surface 110a of the substrate 110 (the upper surface 110a is shown in FIG. 2) and extends in the second direction D2. Each of the second sensing electrodes includes a plurality of second sensing units 122 and a plurality of second conductive lines 124. The adjacent two second sensing units 122 are connected by corresponding second conductive lines 124. The first conductive line 123 and the second conductive line 124 are electrically isolated from each other by an insulating block (not shown). The first direction D1 and the second direction D2 are different directions. For example, the first direction D1 is the X axis direction, and the second direction D2 is the Y axis direction. Further, the material of the first sensing unit 121 and the second sensing unit 122 is, for example, indium tin oxide (ITO). The material of the first conductive line 123 and the second conductive line 124 is, for example, a metal.

基板110例如是透光或透明基材，其材質包括高透光率的絕緣性材料，例如是玻璃、聚碳酸酯(Polycarbonate,PC)、聚酯(Polythylene terephthalate,PET)、聚甲基丙烯酸甲酯(Polymethylmethacrylate,PMMA)或環烯烴共聚合物(Cyclic Olefin Copolymer)等材料。The substrate 110 is, for example, a light transmissive or transparent substrate, and the material thereof comprises an insulating material with high light transmittance, such as glass, polycarbonate (PC), polyester (Polythylene terephthalate, PET), polymethyl methacrylate. Polymethylmethacrylate (PMMA) or Cyclic Olefin Copolymer.

如第2圖所示，訊號傳輸線130具有至少一陷入部134，陷入部134位於第一訊號線131與第二訊號線132之間以及第二訊號線132與第三訊號線133之間。As shown in FIG. 2, the signal transmission line 130 has at least one trapping portion 134. The trapping portion 134 is located between the first signal line 131 and the second signal line 132 and between the second signal line 132 and the third signal line 133.

請參照第3圖，其繪示第1圖中局部3’的放大圖。訊號傳輸線130具有至少一孔洞135，孔洞135位於第一訊號線131與第二訊號線132之間。相似地，孔洞135亦可位於第二訊號線132與第三訊號線133之間。Please refer to Fig. 3, which shows an enlarged view of a portion 3' in Fig. 1. The signal transmission line 130 has at least one hole 135 between the first signal line 131 and the second signal line 132. Similarly, the hole 135 can also be located between the second signal line 132 and the third signal line 133.

如第3圖所示，訊號傳輸線130係由第一訊號線131與第二訊號線132彼此接觸以及第二訊號線132與第三訊號線133彼此接觸所形成。在相鄰二訊號傳輸線130中，其中一訊號傳輸線130(例如是位於第3圖左邊)的第三訊號線133是細的，故其邊緣凹、凸部的凹凸幅度較小，而另一訊號傳輸線130(例如是位於第3圖右邊)的第一訊號線131是細的，故其邊緣凹、凸部的凹凸幅度較小，如此一來，相鄰二訊號傳輸線130之間保持一安全距離S1而不會彼此接觸而短路，如此有助於穩定地控制製程。此外，由於相鄰二訊號傳輸線130不容易彼此接觸，使得相鄰二訊號傳輸線130的間距可以更接近，如此可縮小觸控面板100的尺寸。As shown in FIG. 3, the signal transmission line 130 is formed by the first signal line 131 and the second signal line 132 being in contact with each other and the second signal line 132 and the third signal line 133 being in contact with each other. In the adjacent two-signal transmission line 130, the third signal line 133 of one of the signal transmission lines 130 (for example, located on the left side of FIG. 3) is thin, so that the concave and convex portions of the edge are small, and the other signal is small. The first signal line 131 of the transmission line 130 (for example, the right side of FIG. 3) is thin, so that the concave and convex portions of the edge are small, so that a safe distance is maintained between the adjacent two signal transmission lines 130. S1 does not short-circuit with each other, which helps to stably control the process. In addition, since the adjacent two signal transmission lines 130 are not easily in contact with each other, the spacing of the adjacent two signal transmission lines 130 can be closer, so that the size of the touch panel 100 can be reduced.

上述訊號傳輸線130的設計亦可應用於其它種類之面板中，以下係以應用於顯示面板為例說明。The design of the above signal transmission line 130 can also be applied to other types of panels. The following is applied to the display panel as an example.

請參照第4圖，其繪示依照本發明另一實施例之顯示面板的局部上視圖。顯示面板300包括基板110、主動元件陣列結構層320及至少一訊號傳輸線130。Please refer to FIG. 4, which is a partial top view of a display panel in accordance with another embodiment of the present invention. The display panel 300 includes a substrate 110, an active device array structure layer 320, and at least one signal transmission line 130.

Each of the signal transmission lines 130 of the display panel 300 is connected to a corresponding data line 321 or a corresponding scan line 322. Further, the active element 323 is, for example, a thin film transistor.

訊號傳輸線130連接於主動元件陣列結構層320且對應非可視區R2形成於基板110上。訊號傳輸線130連接一電路板(未繪示)，其可傳輸資料線321及掃描線322的訊號至該電路板。The signal transmission line 130 is connected to the active device array structure layer 320 and the corresponding non-visible area R2 is formed on the substrate 110. The signal transmission line 130 is connected to a circuit board (not shown), which can transmit the signals of the data line 321 and the scan line 322 to the circuit board.

請參照第5A至5C圖，其繪示依照本發明一實施例之網版的示意圖。第5A圖繪示用以形成第1圖之訊號傳輸線之網版的上視圖，第5B圖繪示第5A圖中局部5B’的放大圖，第5C圖繪示第5B圖中沿方向5C-5C’的剖視圖。Please refer to FIGS. 5A-5C for a schematic diagram of a screen according to an embodiment of the invention. 5A is a top view of a screen for forming a signal transmission line of FIG. 1, FIG. 5B is an enlarged view of a portion 5B' of FIG. 5A, and FIG. 5C is a view of a direction 5C of FIG. 5B. Cutaway view of 5C'.

如第5A圖所示，網版200包括圖案化層220，其中網版200的圖案化層220之鏤空圖案(例如是訊號線開孔224)對應觸控面板100之基板110的非可視區R2(非可視區R2繪示於第1圖)設置。一實施例中，該些訊號線開孔224之區域對應於基板110的至少一邊；另一實施例中，該些訊號線開孔224之區域對應於基板110的整個邊緣配置。訊號傳輸線130的走向可對應不同設計之感應結構120而定，故該些訊號線開孔224之配置區域可對應感應結構120的設計而定，本實施例不作任何限制。後續步驟中，導電材料可透過圖案化層220之該些訊號線開孔224而形成於觸控面板100之基板110上。As shown in FIG. 5A, the screen 200 includes a patterned layer 220, wherein the hollow pattern of the patterned layer 220 of the screen 200 (eg, the signal line opening 224) corresponds to the non-visible area R2 of the substrate 110 of the touch panel 100. (The non-visible area R2 is shown in Figure 1). In one embodiment, the areas of the signal line openings 224 correspond to at least one side of the substrate 110. In another embodiment, the areas of the signal line openings 224 correspond to the entire edge of the substrate 110. The direction of the signal transmission line 130 can be determined according to the sensing structure 120 of different designs. Therefore, the configuration area of the signal line opening 224 can be determined according to the design of the sensing structure 120. This embodiment does not impose any limitation. In the subsequent step, the conductive material is formed on the substrate 110 of the touch panel 100 through the signal line openings 224 of the patterned layer 220.

如第5B圖所示，圖案化層220具有至少一第一訊號線開孔221、至少一第二訊號線開孔222及至少一第三訊號線開孔223。由於相鄰二訊號線開孔的間距甚小，故相鄰之第一訊號線開孔221、第二訊號線開孔222及第三訊號線開孔223巨觀來看(如第5A圖所示)如同單條訊號線開孔224。As shown in FIG. 5B, the patterned layer 220 has at least one first signal line opening 221, at least one second signal line opening 222, and at least one third signal line opening 223. Since the spacing between the adjacent two signal lines is very small, the adjacent first signal line opening 221, the second signal line opening 222, and the third signal line opening 223 are generally viewed (as shown in FIG. 5A). Show) as a single signal line opening 224.

如第5B圖所示，相鄰二訊號線開孔間隔一間距，以彼此隔離。以第一訊號線開孔221與第二訊號線開孔222為例說明，第一訊號線開孔221與第二訊號線開孔222彼此隔離，其間隔一間距S2。一實施例中，間距S2例如是介於約5至10微米(um)之間。As shown in FIG. 5B, the adjacent two signal line openings are spaced apart by a distance to be isolated from each other. Taking the first signal line opening 221 and the second signal line opening 222 as an example, the first signal line opening 221 and the second signal line opening 222 are isolated from each other by a distance S2. In one embodiment, the spacing S2 is, for example, between about 5 and 10 microns (um).

對於形成寬度為60 um的訊號線(例如是第一訊號線131、第二訊號線132及第三訊號線133)來說，網層210之不銹鋼絲交叉出的網目密度較佳但非限定地係約500個網目/平方英寸；對於形成寬度為30 um的訊號線來說，網層210之不銹鋼絲交叉出的網目密度較佳但非限定地係約650個網目/平方英寸。For forming a signal line having a width of 60 um (for example, the first signal line 131, the second signal line 132, and the third signal line 133), the mesh density of the stainless steel wires of the mesh layer 210 is preferably but not limited. Approximately 500 mesh/square inch; for forming a signal line having a width of 30 um, the mesh density of the stainless steel wire of the mesh layer 210 is preferably, but not limited to, about 650 mesh/square inch.

如第5C圖所示，網版200更包括網層210。網層210例如是由數條不銹鋼絲交叉而成。圖案化層220的材質例如是乳劑，其形成於網層210上。As shown in FIG. 5C, the screen 200 further includes a mesh layer 210. The mesh layer 210 is formed, for example, by crossing a plurality of stainless steel wires. The material of the patterned layer 220 is, for example, an emulsion formed on the mesh layer 210.

如第7圖所示，設置網版200於基板110上。其中，圖案化層220之訊號線開孔224的分布區域224R對應基板110之非可視區R2。As shown in FIG. 7, a screen 200 is disposed on the substrate 110. The distribution area 224R of the signal line opening 224 of the patterned layer 220 corresponds to the non-visible area R2 of the substrate 110.

如第8圖(未繪示網版)所示，第8圖繪示第6圖之基板形成有訊號線材料的局部上視圖。以例如是印刷方法，形成第一訊號線材料131’、第二訊號線材料132’及第三訊號線材料133’。其中，第一訊號線材料131’、第二訊號線材料132’及第三訊號線材料133’分別透過網版200之第一訊號線開孔221、第二訊號線開孔222及第三訊號線開孔223(第一訊號線開孔221、第二訊號線開孔222及第三訊號線開孔223繪示於第5B圖)形成於基板110上。第一訊號線材料131’之一端、第二訊號線材料132’之一端及第三訊號線材料133’之一端係連接於感應結構120。As shown in FIG. 8 (not shown in the screen), FIG. 8 is a partial top view showing the material of the signal line formed on the substrate of FIG. 6. The first signal line material 131', the second signal line material 132', and the third signal line material 133' are formed by, for example, a printing method. The first signal line material 131', the second signal line material 132', and the third signal line material 133' respectively pass through the first signal line opening 221, the second signal line opening 222, and the third signal of the screen 200. The line opening 223 (the first signal line opening 221, the second signal line opening 222, and the third signal line opening 223 are shown in FIG. 5B) is formed on the substrate 110. One end of the first signal line material 131', one end of the second signal line material 132', and one end of the third signal line material 133' are connected to the sensing structure 120.

由於第一訊號線材料131’之流動性(例如第一訊號線材料131’呈熔融態)，使第一訊號線材料131’往其二邊緣方向流動而使第一訊號線材料131’之邊緣形成至少一第一凸部131a及至少一第一凹部131b。由於第二訊號線材料132’之流動性，使第二訊號線材料132’往其二邊緣方向流動而使第二訊號線材料132’邊緣形成至少一第二凸部132a及至少一第二凹部132b。由於第三訊號線材料133’之流動性，使第三訊號線材料133’往其二邊緣方向流動而使第三訊號線材料133’邊緣形成至少一第三凸部133a及至少一第三凹部133b。Due to the fluidity of the first signal line material 131' (for example, the first signal line material 131' is in a molten state), the first signal line material 131' is caused to flow toward the edges of the first signal line material 131'. At least one first convex portion 131a and at least one first concave portion 131b are formed. Due to the fluidity of the second signal line material 132 ′, the second signal line material 132 ′ flows toward the two edges thereof to form the edge of the second signal line material 132 ′ to form at least one second protrusion 132 a and at least one second recess 132b. Due to the fluidity of the third signal line material 133 ′, the third signal line material 133 ′ flows in the two edge directions thereof to form the third signal line material 133 ′ edge to form at least one third convex portion 133 a and at least one third concave portion. 133b.

此外，第一訊號線材料131’例如是金屬，如銀(Ag)或銅(Cu)。第二訊號線材料132’之材質及第三訊號線材料133’之材質可相似於第一訊號線材料131’，容此不再贅述。Further, the first signal line material 131' is, for example, a metal such as silver (Ag) or copper (Cu). The material of the second signal line material 132' and the material of the third signal line material 133' may be similar to the first signal line material 131', and will not be described again.

如第8圖(未繪示網版)所示，雖然第一訊號線材料131’、第二訊號線材料132’及第三訊號線材料133’分別透過分離之訊號線開孔形成於基板，然而，由於訊號線材料的流動性，使相鄰二訊號線材料形成於基板110上後流動而連接在一起。以第一訊號線材料131’與第二訊號線材料132’為例說明，當第一訊號線材料131’及第二訊號線材料132’分別透過第一訊號線開孔221及第二訊號線開孔222形成於基板110上後，第一訊號線材料131’及第二訊號線材料132’可流動經過間距S2而彼此電性接觸。進一步地說，第一訊號線開孔221及第二訊號線開孔222形成於基板110上後，第一訊號線材料131’可流向第二訊號線材料132’而接觸於第二訊號線材料132’，而第二訊號線材料132’可流向第一訊號線材料131’而接觸於第一訊號線材料131’As shown in FIG. 8 (not shown), the first signal line material 131', the second signal line material 132', and the third signal line material 133' are respectively formed on the substrate through the separated signal line openings. However, due to the fluidity of the signal line material, the adjacent two signal line materials are formed on the substrate 110 and flow and are connected together. Taking the first signal line material 131' and the second signal line material 132' as an example, when the first signal line material 131' and the second signal line material 132' pass through the first signal line opening 221 and the second signal line, respectively. After the opening 222 is formed on the substrate 110, the first signal line material 131' and the second signal line material 132' can flow through the gap S2 to be in electrical contact with each other. Further, after the first signal line opening 221 and the second signal line opening 222 are formed on the substrate 110, the first signal line material 131' can flow to the second signal line material 132' to contact the second signal line material. 132', and the second signal line material 132' can flow to the first signal line material 131' and contact the first signal line material 131'

在上述間距S2(第5B圖)的設計下，第一訊號線材料131’在流動後，其第一凸部131a會流向鄰近之第二訊號線材料132’而接觸鄰近之第二訊號線材料132’，使第一訊號線材料131’藉由第一凸部131a的流動而與第二訊號線材料132’電性接觸。此外，在間距S2的設計下，第二訊號線材料132’在流動後，其第二凸部132a會流向鄰近之第一訊號線材料131’並接觸鄰近之第一訊號線材料131’，使第二訊號線材料132’藉由第二凸部132a的流動而與第二訊號線材料132’電性接觸。In the design of the spacing S2 (Fig. 5B), after the first signal line material 131' flows, the first convex portion 131a flows to the adjacent second signal line material 132' to contact the adjacent second signal line material. 132', the first signal line material 131' is electrically contacted with the second signal line material 132' by the flow of the first convex portion 131a. In addition, under the design of the spacing S2, after the second signal line material 132' flows, the second convex portion 132a flows to the adjacent first signal line material 131' and contacts the adjacent first signal line material 131', so that The second signal line material 132' is in electrical contact with the second signal line material 132' by the flow of the second protrusion 132a.

當第一凸部131a及第二凸部132a同時形成時，第一凸部131a及第二凸部132a分別流向對方而在更短的流動距離內彼此接觸。如此一來，第一訊號線材料131’及第二訊號線材料132’在冷卻凝固前可迅速接觸。一實施例中，間距S2可介於約5至10 um之間。When the first convex portion 131a and the second convex portion 132a are simultaneously formed, the first convex portion 131a and the second convex portion 132a flow toward each other and contact each other within a shorter flow distance. As a result, the first signal line material 131' and the second signal line material 132' can be quickly contacted prior to cooling and solidification. In one embodiment, the spacing S2 can be between about 5 and 10 um.

如第9圖所示，在第一訊號線材料131’、第二訊號線材料132’及第三訊號線材料133’流動而接觸後，第一訊號線材料131’、第二訊號線材料132’及第三訊號線材料133’形成訊號傳輸線130。As shown in FIG. 9, after the first signal line material 131', the second signal line material 132', and the third signal line material 133' flow and contact, the first signal line material 131' and the second signal line material 132 The 'and third signal line material 133' forms a signal transmission line 130.

如第9圖所示，訊號傳輸線130之該些訊號線材料流動接觸後，相鄰二訊號線之間可形成至少一孔洞。以第一訊號線材料131’與第二訊號線材料132’為例說明，由於第一訊號線材料131’之第一凸部131a(第8圖)與第二訊號線材料132’之第二凹部132b(第8圖)之間的空隙較大，在第一訊號線材料131’及第二訊號線材料132’流動的過程中，若訊號線材料來不及填滿相鄰之第一凸部131a與第二凹部132b，則未被填滿的第一凸部131a與第二凹部132b便形成孔洞135。另一實施例中，孔洞135可形成於相鄰二凹部之間，例如是形成於第一凹部131b與第二凹部132b之間，或形成於第二凹部132b與第三凹部133b之間。As shown in FIG. 9, after the signal line materials of the signal transmission line 130 are in fluid contact, at least one hole may be formed between the adjacent two signal lines. Taking the first signal line material 131' and the second signal line material 132' as an example, the first convex portion 131a (Fig. 8) of the first signal line material 131' and the second signal line material 132' are second. The gap between the recesses 132b (Fig. 8) is large. During the flow of the first signal line material 131' and the second signal line material 132', if the signal line material does not have to fill the adjacent first convex portion 131a And the second concave portion 132b, the first convex portion 131a and the second concave portion 132b which are not filled are formed with the holes 135. In another embodiment, the hole 135 may be formed between the adjacent two recesses, for example, between the first recess 131b and the second recess 132b, or between the second recess 132b and the third recess 133b.

然後，烘烤第9圖之訊號傳輸線130，使訊號傳輸線130固化。烘烤方法例如是加熱或照射紫外光。若採用加熱方法，加熱溫度例如是介於攝氏約130至攝氏約150度之間，而加熱時間介於約45分鐘至約60分鐘之間。Then, the signal transmission line 130 of FIG. 9 is baked to cure the signal transmission line 130. The baking method is, for example, heating or irradiating ultraviolet light. If a heating method is employed, the heating temperature is, for example, between about 130 degrees Celsius and about 150 degrees Celsius, and the heating time is between about 45 minutes and about 60 minutes.

本實施例中，可採用至少二訊號線開孔(如第5B圖中網版200之訊號線開孔221、222或223)形成單條訊號傳輸線130(第9圖)。在下次改變訊號傳輸線130之寬度的設計變更中，可繼續沿用至少二條訊號線開孔(訊號線開孔221、222或223)形成寬度不同於訊號傳輸線130之訊號傳輸線，如此一來，可節省驗證新寬度之訊號線開孔(或新寬度之訊號傳輸線)的驗證時間。In this embodiment, at least two signal line openings (such as the signal line openings 221, 222 or 223 of the screen 200 in FIG. 5B) may be used to form a single signal transmission line 130 (Fig. 9). In the design change of changing the width of the signal transmission line 130 next time, at least two signal line openings (signal line openings 221, 222 or 223) can be continuously used to form a signal transmission line having a width different from that of the signal transmission line 130, thereby saving Verify the verification time of the new width signal line opening (or the new width signal transmission line).

此外，上述顯示面板300的製造方法相似於觸控面板100的製造方法，容此不再贅述。In addition, the manufacturing method of the display panel 300 is similar to the manufacturing method of the touch panel 100, and details are not described herein again.

另外，上述觸控面板100及顯示面板300亦可同時應用於電子產品領域，以下係舉例說明。In addition, the touch panel 100 and the display panel 300 described above can also be applied to the field of electronic products at the same time.

請參照第10圖，其繪示依照本發明一實施例之電子裝置的剖視圖。觸控顯示面板400可包括觸控面板100、顯示面板300、框架410及控制器(未繪示)。觸控面板100對應顯示面板300配置，框架410圍繞且固定觸控面板100及顯示面板300。控制器例如是電路板，其可控制及處理來自於或傳送至觸控面板100及顯示面板300的訊號。Referring to FIG. 10, a cross-sectional view of an electronic device in accordance with an embodiment of the present invention is shown. The touch display panel 400 can include a touch panel 100, a display panel 300, a frame 410, and a controller (not shown). The touch panel 100 is disposed corresponding to the display panel 300 , and the frame 410 surrounds and fixes the touch panel 100 and the display panel 300 . The controller is, for example, a circuit board that can control and process signals from or transmitted to the touch panel 100 and the display panel 300.

另一實施例中，觸控顯示面板400可配置觸控面板100與顯示面板300之一者。例如，觸控顯示面板400可包括觸控面板100及另一顯示面板；或者，觸控顯示面板400可包括顯示面板300及另一觸控面板。In another embodiment, the touch display panel 400 can be configured with one of the touch panel 100 and the display panel 300. For example, the touch display panel 400 can include the touch panel 100 and another display panel. Alternatively, the touch display panel 400 can include the display panel 300 and another touch panel.

本發明上述實施例之觸控面板及其製造方法，多條細的訊號線構成單條訊號傳輸線，使訊號傳輸線的邊緣凹、凸部甚小，如此相鄰二傳輸訊號線彼此接觸而短路的機率很小。此外，由於訊號傳輸線的邊緣凹、凸部甚小，故相鄰二訊號傳輸線的間距可縮小，以縮小面板尺寸。In the touch panel and the manufacturing method thereof, the plurality of thin signal lines constitute a single signal transmission line, so that the edges of the signal transmission line are concave and convex, and the probability of the adjacent two transmission signal lines contacting each other is short-circuited. Very small. In addition, since the edge of the signal transmission line is concave and the convex portion is very small, the spacing of the adjacent two signal transmission lines can be reduced to reduce the size of the panel.

綜上所述，雖然本發明已以實施例揭露如上，然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾。因此，本發明之保護範圍當視後附之申請專利範圍所界定者為準。In conclusion, the present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention.
