Fig. 2A to 2D are schematic diagrams illustrating a manufacturing process of a touch display device according to an embodiment of the invention.
Referring to fig. 2A, first, a display module 200 having a display surface 200T, an arc-shaped side surface 200S and a rear surface 200B is provided. In some embodiments, the display surface 200T may be a surface of the display surface 210T of the display panel 210. In some embodiments, the arcuate side surface 200S may be the arcuate surface 220S of the arcuate structure 220 described above. In some embodiments, the rear surface 200B may be a surface of the backlight module 230, the frame 240 or other components.
In some embodiments, at least a portion 300A of the touch sensing film 300 is fixed on the display surface 200T of the display module 200. Specifically, the optical adhesive a1 is attached to the portion 300A of the touch sensing film 300 and the cover 400, and the optical adhesive a2 is attached to the display module 200 and the portion 300A of the touch sensing film 300.
Herein, the fixing glue G1 is disposed on the rear surface 200B of the display module 200 to facilitate the subsequent adhesion of the touch sensing film 300. Of course, the scope of the invention should not be limited thereto, and in other embodiments, the fixing glue G1 may be disposed on the portion 300C of the touch sensing film 300.
Referring to fig. 2B, the roller 900 presses the portion 300B of the touch sensing film 300, so that the portion 300B of the touch sensing film 300 is bent along the arc-shaped side surface 200S of the display module 200. For example, the roller 900 applies a force to the arc-shaped side surface 200S in the direction N1 and rolls in the direction N2. The direction N1 is perpendicular to the arc-shaped side surface 200S, and the direction N2 may be parallel to the rear surface 200B, for example, parallel to the aforementioned direction D1 (refer to fig. 1). In this way, during the bending process, the arc-shaped side surface 200S can keep the touch sensing film 300 pressed in the forward direction (e.g., the direction N1), so as to avoid scratching the touch electrode or affecting the electrical performance.
Referring to fig. 2C, the roller 900 rolls from the arc-shaped side surface 200S of the display module 200 to the rear surface 200B of the display module 200, so that the portion 300C of the touch sensing film 300 at least partially contacts the fixing glue G1, and is further fixed on the rear surface 200B of the display module 200.
Referring to fig. 2D, the portion 300C of the touch sensing film 300 can be flatly attached to the rear surface 200B of the display module 200, so as to obtain the touch display device 100.
Fig. 3 is a schematic cross-sectional view of a touch display device according to an embodiment of the invention. The difference between this embodiment and the embodiment of fig. 1 is that: in the present embodiment, the arc-shaped structure 220 and the frame 240 are integrally formed, and may be formed by the same Molding process. For example, the arc-shaped structure 220 and the frame 240 are made of the same material and are connected seamlessly. Other details of the present embodiment are substantially as described above and will not be described again.
Fig. 4 is a schematic cross-sectional view of a touch display device according to an embodiment of the invention. The difference between this embodiment and the embodiment of fig. 1 is that: in the present embodiment, the touch display device 100 further includes protection layers 710 and 720. The protection layers 710 and 720 are disposed on the portions of the touch sensing film 300 not contacting the optical colloids a1 and a 2. For example, the protection layers 710 and 720 are disposed on two opposite surfaces of the portion 300B of the touch sensing film 300. The protection layers 710 and 720 may also extend to two opposite surfaces of the portion 300C of the touch sensing film 300. The material of the protection layers 710, 720 may be protective ink or other suitable material, which may be formed by deposition, plating, etc. The protection layer 720 may contact the arc surface 220S of the arc structure 220 to protect the touch electrode on the portion 300B of the touch sensing film 300 during a bending process (e.g., a process of pressing with a roller). Other details of the present embodiment are substantially as described above and will not be described again.
Fig. 5 is a schematic cross-sectional view of a touch display device according to an embodiment of the invention. The difference between this embodiment and the embodiment of fig. 1 is that: in this embodiment, the touch display device 100 further includes a pressure sensing layer 800, and the pressure sensing layer 800 is disposed between the portion 300C of the touch sensing film 300 and the rear surface 210B of the display panel 210. In some embodiments, the portion 300C of the touch sensing film 300 and the pressure sensing layer 800 can be used together to sense pressure. Specifically, the magnitude of the pressing force can be estimated by detecting the changes of the characteristics (such as capacitance and resistance) of the touch sensing film 300 and the pressure sensing layer 800. For example, the pressure sensing layer 800 may include a pressure dielectric layer and an electrode layer, the pressure dielectric layer being sandwiched between the portion 300C and the electrode layer, the thickness of the pressure dielectric layer varying with the applied pressure. Accordingly, by measuring the capacitance change between the electrode layer and the portion 300C of the touch sensing film 300, the magnitude of the pressing force can be estimated. In some embodiments, the fixing glue G1 may connect the pressure sensing layer 800 and the display module 200. The adhesive G1 can be used as an anti-interference layer to prevent noise from interfering with touch and pressure signals. Other details of the present embodiment are substantially as described above and will not be described again.
Fig. 6 is a schematic top view of a touch sensing film according to an embodiment of the invention. The touch sensing film 300 of the present embodiment includes a single layer of touch electrodes. Specifically, the touch sensing film 300 includes a substrate 310, a plurality of touch electrodes 322, and traces 330. The touch electrodes 322 are disposed on the substrate 310, and the traces 330 respectively connect the touch electrodes 322 to the flexible circuit board 500. The flexible printed circuit 500 may be provided with a processing chip (not shown) for processing the touch signal. In some embodiments, the touch electrode 322 is located on the portion 300A and the portion 300B, so as to realize touch sensing of the portion 300A and the portion 300B. The trace 330 is substantially located on the portion 300C and disposed on the rear surface 210B of the display panel 210. Therefore, most of the traces 330 are not located in the portion 300A, and do not occupy the front surface (e.g., the display surface 210T) of the display panel 210, thereby implementing a narrow bezel design. In some embodiments, the touch electrode 322 extends to the portion 300C and is also located at the portion 300C, so as to improve the edge sensing effect of the portion 300B and make the side touch effect thereof better.
Fig. 7 is a schematic top view of a touch sensing film according to an embodiment of the invention. The present embodiment differs from the embodiment of fig. 6 in that: the present embodiment includes two axial touch electrodes 322 and 324. Specifically, the touch sensing film 300 includes a substrate 310 and a plurality of touch electrodes 322 and 324 disposed on the substrate 310. As shown, the touch electrodes 322 are arranged in a first axial direction, the touch electrodes 324 are arranged in a second axial direction, and the touch electrodes 322 and the touch electrodes 324 are disposed on the same surface of the substrate 310 in an intersecting and insulating manner. Specifically, the touch sensing film 300 includes a connection line 326, a bridge line 352, and an insulation block 362. The connection line 326 and the touch electrodes 322 and 324 can be formed by patterning the same transparent electrode layer. The connection lines 326 connect the adjacent touch electrodes 324. The bridging wires 352 connect the adjacent touch electrodes 322. The bridging wire 352 may be formed of a transparent or opaque conductive material. The bridging wire 352 may be comprised of a metal, such as copper. The insulating block 362 is disposed between the connection line 326 and the bridge wire 352 and separates the connection line 326 from the bridge wire 352, so as to electrically isolate the touch electrodes 322, 324.
Similarly, in some embodiments, the touch electrodes 322 and 324 can be located on the portion 300A and the portion 300B, and the trace 330 is located on the portion 300C and disposed on the rear surface 210B of the display panel 210. Therefore, most of the traces 330 are not located in the portion 300A, and do not occupy the front surface (e.g., the display surface 210T) of the display panel 210, thereby implementing a narrow bezel design. In some embodiments, the touch electrodes 322 and 324 are also located in the portion 300C.
Fig. 8A and 8B are top views of a touch sensing film according to an embodiment of the invention. The present embodiment differs from the embodiment of fig. 6 in that: in this embodiment, the touch sensing film 300 includes two layers of touch electrodes. Specifically, the touch sensing film 300 includes a touch electrode 322 and a touch electrode 342 respectively disposed on the surface 310A and the surface 310B of the substrate 310. The touch electrodes 322 and the touch electrodes 322 are respectively connected to the conductive traces (not shown) in the peripheral area, and the touch signals are transmitted to the controller through the conductive traces in the peripheral area for calculation, so as to determine the coordinates of the touch position. Although the touch electrodes 322 and 342 are disposed on two opposite surfaces of the same substrate 310, the scope of the invention should not be limited thereto, and the touch electrodes 322 and 342 may be disposed on surfaces of different substrates in other embodiments.
Similarly, in some embodiments, the touch electrodes 322 and 342 are also located on the portions 300A and 300B, and the trace 330 is located on the portion 300C and disposed on the rear surface 210B of the display panel 210. Therefore, most of the traces 330 are not located in the portion 300A, and do not occupy the front surface (e.g., the display surface 210T) of the display panel 210, thereby implementing a narrow bezel design. In some embodiments, the touch electrodes 322 and 342 are also located in the portion 300C.
In some of the embodiments described above, the substrate 310 is a flexible substrate. In some embodiments, the bendable radius of the substrate 310 may be less than 1 mm, for example, less than 0.5 mm. Specifically, the flexibility of the substrate 310 may be higher than that of the cap plate 400. In some embodiments, the substrate 310 may be a transparent inorganic substrate or a transparent organic substrate, such as glass or plastic, such as a plastic substrate, for example, polyethylene terephthalate, polycarbonate, polyethylene or polymethyl methacrylate. In some embodiments, the material of the substrate 310 may be different from the material of the cover plate 400.
The touch electrodes 322, 324, 342 can be made of a transparent conductive material, and the transparent conductive material can be selected from one or a combination of the following groups: indium Tin Oxide (ITO), antimony tin oxide (Α Τ O), zinc oxide (ZnO), zinc dioxide (ZnO2), tin dioxide (SnO2), indium oxide (In2O 3). Alternatively, the touch electrodes 322, 324, 342 may be a metal mesh, and the material thereof may be metal, such as silver or copper. In other embodiments, the touch electrodes 322, 324, 342 may include graphene, nano silver, carbon nanotubes, etc.
In various embodiments of the present invention, the flexible touch sensing film is designed to wind from the display surface to the back surface of the display panel, so that the traces of the touch panel are disposed on the back surface of the display panel, not the display surface. Therefore, the design of the narrow frame is realized. In addition, the display module is provided with an arc-shaped side surface, so that the touch sensing film can be bent along the arc-shaped side surface, the risk of scratching of the touch electrode is reduced, and the electrical property of the touch sensing film is maintained to provide side touch.
