可撓式基材210適於保護位於其下的觸控元件110。在本實施例中，可撓式基材210的厚度H210大於分離層120的厚度H120且小於25μm，例如介於3μm至12.5μm之間。由於觸控元件110被可撓式基材210覆蓋，且可撓式基材210的厚度H210大於 分離層120的厚度H120，因此在後續接合可撓式印刷電路板(Flexible Printed Circuit board,FPC)的步驟中，可撓式印刷電路板可由分離層120背對第一訊號傳輸層TM1的表面分別接合於第一導線116以及第二導線118。在此架構下，絕緣層115對應第二導線118的位置可先形成貫孔。可撓式印刷電路板可再透過異方性導電膜(anisotropic conductive film,ACF)刺穿分離層120對應第一導線116以及第二導線118的位置，以接合第一導線116以及第二導線118。 The flexible substrate 210 is adapted to protect the touch element 110 located thereunder. In the present embodiment, the thickness H210 of the flexible substrate 210 is greater than the thickness H120 of the separation layer 120 and less than 25 μm, for example, between 3 μm and 12.5 μm. Since the touch element 110 is covered by the flexible substrate 210, the thickness H210 of the flexible substrate 210 is greater than The thickness of the separation layer 120 is H120. Therefore, in the subsequent step of bonding the flexible printed circuit board (FPC), the flexible printed circuit board can be separated from the surface of the first signal transmission layer TM1 by the separation layer 120. Bonded to the first wire 116 and the second wire 118. Under this structure, the insulating layer 115 can form a through hole corresponding to the position of the second wire 118. The flexible printed circuit board can further penetrate the position of the separation layer 120 corresponding to the first wire 116 and the second wire 118 by an anisotropic conductive film (ACF) to bond the first wire 116 and the second wire 118. .

請參照圖3，可撓式觸控面板300與圖2的可撓式觸控面板200的主要差異在於觸控元件110A包括第一訊號傳輸層TM1以及第二訊號傳輸層TM2，其中第一訊號傳輸層TM1以及第二訊號傳輸層TM2分別設置在可撓式基材210的相對兩表面上，且第二訊號傳輸層TM2藉由可撓式基材210電性絕緣於第一訊號傳輸層TM1。因此，觸控元件110A可省略圖2中的絕緣層115。 The main difference between the flexible touch panel 300 and the flexible touch panel 200 of FIG. 2 is that the touch component 110A includes a first signal transmission layer TM1 and a second signal transmission layer TM2, wherein the first signal The transmission layer TM1 and the second signal transmission layer TM2 are respectively disposed on opposite surfaces of the flexible substrate 210, and the second signal transmission layer TM2 is electrically insulated from the first signal transmission layer TM1 by the flexible substrate 210. . Therefore, the touch element 110A can omit the insulating layer 115 in FIG.

在本實施例中，第一訊號傳輸層TM1配置在分離層120上且位於可撓式基材210與分離層120之間。第二訊號傳輸層TM2配置在可撓式基材210上，且可撓式基材210位於第二訊號傳輸層TM2與第一訊號傳輸層TM1之間。可撓式印刷電路板可由分離層120背對第一訊號傳輸層TM1的表面接合於第一導線116，且由第二訊號傳輸層TM2背對可撓式基材210的表面接合於第二導線118，但不以此為限。 In the present embodiment, the first signal transmission layer TM1 is disposed on the separation layer 120 and between the flexible substrate 210 and the separation layer 120. The second signal transmission layer TM2 is disposed on the flexible substrate 210, and the flexible substrate 210 is located between the second signal transmission layer TM2 and the first signal transmission layer TM1.

請參照圖4，可撓式觸控面板400與圖3的可撓式觸控面 板300的主要差異在於可撓式觸控面板400更包括保護層410，以供第二訊號傳輸層TM2適當的保護。保護層410配置在第二訊號傳輸層TM2上，且第二訊號傳輸層TM2位於保護層410與可撓式基材210之間。保護層410可以是與可撓式基材210相似之可撓式基材。在雙層可撓式基材的疊構下，可在可撓式基材210製作通孔，以將第二訊號傳輸層TM2以及第一訊號傳輸層TM1拉線至同一平面，進而可以減少之後與可撓式印刷電路板接出訊號時的接合次數。另外，保護層410也可製作通孔至外表面。保護層410的通孔必須與可撓式基材210的通孔錯位，讓第一訊號傳輸層TM1連結至第二訊號傳輸層TM2，再透過保護層410的通孔與可撓式印刷電路板接合。此做法不需要進行分離層120的穿剌。在設置其他訊號層或導線的實施例中，可同此作法再製作出其他訊號層或導線。 Referring to FIG. 4, the flexible touch panel 400 and the flexible touch surface of FIG. 3 The main difference of the board 300 is that the flexible touch panel 400 further includes a protective layer 410 for proper protection of the second signal transmission layer TM2. The protective layer 410 is disposed on the second signal transmission layer TM2, and the second signal transmission layer TM2 is located between the protective layer 410 and the flexible substrate 210. The protective layer 410 can be a flexible substrate similar to the flexible substrate 210. In the stack of the double-layer flexible substrate, a through hole can be formed in the flexible substrate 210 to pull the second signal transmission layer TM2 and the first signal transmission layer TM1 to the same plane, thereby reducing the The number of joints when the signal is received from the flexible printed circuit board. In addition, the protective layer 410 can also form through holes to the outer surface. The through hole of the protective layer 410 must be misaligned with the through hole of the flexible substrate 210 to connect the first signal transmission layer TM1 to the second signal transmission layer TM2, and then pass through the through hole of the protective layer 410 and the flexible printed circuit board. Engage. This practice does not require the piercing of the separation layer 120. In embodiments in which other signal layers or wires are provided, other signal layers or wires can be fabricated in the same manner.

圖5A至圖5E是依照本發明的第一實施例的一種可撓式觸控面板的製造流程的剖面示意圖。圖5F是將圖5E的可撓式觸控面板轉移至顯示面板的剖面示意圖。圖5G是依照本發明的第一實施例的一種觸控顯示面板的剖面示意圖。請參照圖5A至圖5E，可撓式觸控面板(如圖1A及圖1B的可撓式觸控面板100)的製造方法包括以下步驟。請參照圖5A，於承載基板10上形成離型層20。承載基板10是硬質基板，如玻璃基板、或是其他具有一定剛性之基板，以在製作過程中保持其原有型態而不致變形。 5A to 5E are schematic cross-sectional views showing a manufacturing process of a flexible touch panel according to a first embodiment of the present invention. FIG. 5F is a cross-sectional view showing the transfer of the flexible touch panel of FIG. 5E to the display panel. 5G is a cross-sectional view of a touch display panel in accordance with a first embodiment of the present invention. Referring to FIG. 5A to FIG. 5E , the manufacturing method of the flexible touch panel (such as the flexible touch panel 100 of FIGS. 1A and 1B ) includes the following steps. Referring to FIG. 5A, a release layer 20 is formed on the carrier substrate 10. The carrier substrate 10 is a rigid substrate such as a glass substrate or other substrate having a certain rigidity to maintain its original shape during deformation without deformation.

形成離型層20的方法可包括印刷、塗佈或沉積方式(如蒸 鍍)。離型層20的設置可降低設置於其上的膜層與承載基板10之間的附著力，使設置於其上的膜層易於進行後續脫離的步驟。離型層20的材質可包括聚對二甲基苯(parylene)或聚亞醯胺(Polyimide)，但不以此為限。 The method of forming the release layer 20 may include printing, coating or deposition methods (such as steaming) plating). The provision of the release layer 20 reduces the adhesion between the film layer disposed thereon and the carrier substrate 10, so that the film layer disposed thereon is easily subjected to the subsequent detachment step. The material of the release layer 20 may include, but is not limited to, parylene or polyimide.

請參照圖5B，於離型層20上形成分離層120。形成分離層120的方法可包括印刷、塗佈或沉積方式(如蒸鍍)。分離層120的材質及厚度H120可參照上述，於此不再贅述。 Referring to FIG. 5B, a separation layer 120 is formed on the release layer 20. The method of forming the separation layer 120 may include printing, coating, or deposition methods such as evaporation. For the material and thickness H120 of the separation layer 120, reference may be made to the above, and details are not described herein again.

請參照圖5C，於分離層120上形成觸控元件110，其中分離層120接觸觸控元件110的表面S是連續性的平面。觸控元件110的結構可參照上述於此不再贅述。由於觸控元件110與分離層120之間的附著力高於觸控元件110與離型層20之間的附著力，因此相比於直接將觸控元件110設置在離型層20上，本實施例可降低觸控元件110脫附(peel off)的機率，從而提升製程的穩定性及良率。此外，由於觸控元件110與分離層120之間的附著力高於分離層120與離型層20之間的附著力，因此配置有觸控元件110的分離層120易於進行後續脫離步驟。 Referring to FIG. 5C, the touch element 110 is formed on the separation layer 120, wherein the surface S of the separation layer 120 contacting the touch element 110 is a continuous plane. For the structure of the touch element 110, reference may be made to the above description. Since the adhesion between the touch element 110 and the separation layer 120 is higher than the adhesion between the touch element 110 and the release layer 20, the touch element 110 is disposed on the release layer 20 directly. The embodiment can reduce the probability of the touch element 110 peeling off, thereby improving the stability and yield of the process. In addition, since the adhesion between the touch element 110 and the separation layer 120 is higher than the adhesion between the separation layer 120 and the release layer 20, the separation layer 120 configured with the touch element 110 is easy to perform the subsequent detachment step.

請參照圖5D及圖5E，使配置有觸控元件110的分離層120脫離離型層20。在本實施例中，使配置有觸控元件110的分離層120脫離離型層20的方法包括以下步驟。請參照圖5D，於觸控元件110上貼附轉移薄膜30，其中轉移薄膜30與觸控元件110的附著力大於分離層120與離型層20的附著力。請參照圖5E，將轉移薄膜30自離型層20撕起，以使觸控元件110與分離層120 自離型層20脫離。 Referring to FIGS. 5D and 5E , the separation layer 120 on which the touch element 110 is disposed is separated from the release layer 20 . In the embodiment, the method of disengaging the separation layer 120 configured with the touch element 110 from the release layer 20 includes the following steps. Referring to FIG. 5D , the transfer film 30 is attached to the touch component 110 , wherein the adhesion of the transfer film 30 to the touch component 110 is greater than the adhesion of the separation layer 120 and the release layer 20 . Referring to FIG. 5E, the transfer film 30 is torn from the release layer 20 to make the touch element 110 and the separation layer 120. The release layer 20 is detached.

轉移薄膜30可包括薄膜32以及黏著層34。薄膜32可為一般的塑膠薄膜，如聚对苯二甲酸乙二酯(PET)等常用塑膠，而黏著層34為黏著力可變化的黏著層，例如可為紫外光減黏型黏著層或冷熱變化減黏型黏著層。以紫外光減黏型黏著層為例，在轉移薄膜30將配置有觸控元件110的分離層120自離型層20取下後，可透過紫外光照射黏著層34來降低黏著層34的黏性，以利轉移薄膜30與觸控元件110分離，而完成圖1A中可撓式觸控面板100的製作。 Transfer film 30 can include film 32 and an adhesive layer 34. The film 32 can be a general plastic film, such as a common plastic such as polyethylene terephthalate (PET), and the adhesive layer 34 is an adhesive layer whose adhesive force can be changed, for example, an ultraviolet light-reducing adhesive layer or hot and cold. Change the sticky adhesion layer. Taking the ultraviolet light-reducing adhesive layer as an example, after the transfer film 30 is disposed from the release layer 20 of the touch element 110, the adhesive layer 34 can be irradiated with ultraviolet light to reduce the adhesion of the adhesive layer 34. The transfer film 30 is separated from the touch element 110 to complete the fabrication of the flexible touch panel 100 of FIG. 1A.

在一實施例中，在圖5E的步驟後，亦可先將可撓式觸控面板100轉移至顯示面板DP上(請參照5F)，再使轉移薄膜30與觸控元件110分離(及請參照圖5G)。如此，可形成觸控顯示面板TDP1。可撓式觸控面板100與顯示面板DP之間可選擇性地設置黏著層，以提升可撓式觸控面板100與顯示面板DP的附著力。此外，在另一實施例中，觸控元件110可位於分離層120與顯示面板DP之間。由於可撓式觸控面板100具有厚度薄及可撓曲等特性，因此採用可撓式觸控面板100的觸控顯示面板TDP1也可具有厚度薄的優點。此外，當觸控顯示面板TDP1的顯示面板DP具有可撓曲特性時，觸控顯示面板TDP1亦具有可撓曲特性。 In an embodiment, after the step of FIG. 5E, the flexible touch panel 100 may be transferred to the display panel DP (refer to 5F), and then the transfer film 30 is separated from the touch component 110 (and Refer to Figure 5G). In this way, the touch display panel TDP1 can be formed. An adhesive layer may be selectively disposed between the flexible touch panel 100 and the display panel DP to improve the adhesion of the flexible touch panel 100 and the display panel DP. In addition, in another embodiment, the touch element 110 can be located between the separation layer 120 and the display panel DP. Since the flexible touch panel 100 has characteristics such as thin thickness and flexibility, the touch display panel TDP1 using the flexible touch panel 100 can also have the advantage of being thin. In addition, when the display panel DP of the touch display panel TDP1 has a flexible property, the touch display panel TDP1 also has a flexible property.

圖6A至圖6D是依照本發明的第一實施例的另一種可撓式觸控面板的製造流程的剖面示意圖。請參照圖6A，在圖5A的步驟後且在離型層20上形成分離層120之前，可進一步於離型層 20上形成黏著層40，以提升後續形成的分離層120與離型層20之間的附著力，避免分離層120與離型層20附著力太弱而在製程中脫附。黏著層40可以沿著離型層20的邊緣設置，而形成一框形圖案，但不以此為限。此外，在形成分離層120時(請參照圖6B)，分離層120覆蓋黏著層40以及黏著層40所暴露出的離型層20。在另一實施例中，可將離型層20的面積縮小，讓分離層120的部分與承載基板10接著或讓分離層120透過黏著層40與承載基板10接著，也可防止脫附。其次，於分離層120上形成觸控元件110(請參照圖6C)。 6A-6D are cross-sectional views showing a manufacturing process of another flexible touch panel according to a first embodiment of the present invention. Referring to FIG. 6A, the release layer may be further formed after the step of FIG. 5A and before the separation layer 120 is formed on the release layer 20. The adhesive layer 40 is formed on the 20 to enhance the adhesion between the subsequently formed separation layer 120 and the release layer 20, and the adhesion between the separation layer 120 and the release layer 20 is prevented from being too weak to be desorbed in the process. The adhesive layer 40 may be disposed along the edge of the release layer 20 to form a frame-shaped pattern, but is not limited thereto. Further, when the separation layer 120 is formed (please refer to FIG. 6B), the separation layer 120 covers the adhesion layer 40 and the release layer 20 exposed by the adhesion layer 40. In another embodiment, the area of the release layer 20 may be reduced, and the portion of the separation layer 120 may be followed by the carrier substrate 10 or the separation layer 120 may be passed through the adhesive layer 40 and the carrier substrate 10 to prevent desorption. Next, the touch element 110 is formed on the separation layer 120 (please refer to FIG. 6C).

請參照圖6D，使配置有觸控元件110的分離層120脫離離型層20的方法包括切割分離層120，以將分離層120黏貼於黏著層40的部分PT1與未黏貼於黏著層40的其餘部分PT2分離。於切割後，可利用圖5E中的轉移薄膜30將配置有觸控元件110的分離層120取下，而完成可撓式觸控面板100的製作。或者，也可接續圖5F及圖5G的步驟，以完成觸控顯示面板TDP1的製作。 Referring to FIG. 6D , the method for removing the separation layer 120 disposed with the touch element 110 from the release layer 20 includes cutting the separation layer 120 to adhere the separation layer 120 to the portion PT1 of the adhesive layer 40 and the non-adhesive layer 40 . The rest of the PT2 is separated. After the dicing, the separation layer 120 on which the touch element 110 is disposed can be removed by using the transfer film 30 in FIG. 5E to complete the fabrication of the flexible touch panel 100. Alternatively, the steps of FIG. 5F and FIG. 5G may be continued to complete the fabrication of the touch display panel TDP1.

圖7A是依照本發明的第二實施例的一種可撓式觸控面板的其中一道製造流程的剖面示意圖。圖7B是依照本發明的第二實施例的一種觸控顯示面板的剖面示意圖。請參照圖7A及圖7B，在使配置有觸控元件110的分離層120脫離離型層20之前，可進一步於離型層120上形成可撓式基材210，其中可撓式基材210的厚度H210可參照前述，於此不再贅述。 7A is a cross-sectional view showing a manufacturing process of a flexible touch panel in accordance with a second embodiment of the present invention. 7B is a cross-sectional view of a touch display panel in accordance with a second embodiment of the present invention. Referring to FIGS. 7A and 7B , the flexible substrate 210 may be further formed on the release layer 120 before the separation layer 120 configured with the touch element 110 is separated from the release layer 20 , wherein the flexible substrate 210 is The thickness H210 can be referred to the foregoing, and details are not described herein again.

在習知觸控面板的製程中，若先形成基板再形成觸控元件，通常在形成基板之後且在形成觸控元件之前會先清洗基板的表面，以確保基板表面的潔淨度。然而，可撓式基材的硬度低，習知清洗基板(硬質基板)的毛刷容易刮傷可撓式基材，因此可撓式基材的清洗無法適用既有的設備。本實施例藉由先形成可撓式基材210再形成觸控元件110，除了可省略上述為了配置觸控元件110而清洗可撓式基材210的步驟之外，還可避免毛刷刮傷可撓式基材210。 In the process of the conventional touch panel, if the substrate is first formed to form a touch element, the surface of the substrate is usually cleaned after the substrate is formed and before the touch element is formed to ensure the cleanliness of the substrate surface. However, the hardness of the flexible substrate is low, and the brush for cleaning the substrate (hard substrate) is easy to scratch the flexible substrate, so that the cleaning of the flexible substrate cannot be applied to existing equipment.
