Detailed Description
The present invention is a great thought to be an improvement and innovation, and after many years of research on a spice music, a touch panel is developed, which can break through the bottleneck of the existing narrow frame design. In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It is to be understood, however, that these practical details are not to be interpreted as limiting, that is, in the manner in which some conventional structures and elements are shown in the drawings in a simplified schematic form in order to practice the present invention.
Fig. 1 is a cross-sectional view of a touch panel according to the present invention. The narrow-bezel touch panel includes a transparent substrate 10, at least one conductive bonding pad layer 12, a touch sensing layer 14, and at least one flexible circuit board 16. The transparent substrate 10 has a visible area 102, and the conductive bonding pad layer 12 is attached on the transparent substrate 10 and located at the periphery of the visible area 102. The touch sensing layer 14 is attached to the visible area 102 of the transparent substrate 10, and a portion of the touch sensing layer 14 is attached to and in contact with the conductive bonding pad layer 12 to form an electrical connection, and the touch sensing layer 14 has a plurality of first axial sensing electrode units 142 and a plurality of second axial sensing electrode units 144, which are insulated from each other. The flexible circuit board 16 is correspondingly attached to the conductive bonding pad layer 12 to form an electrical connection. The transparent substrate 10 may be a hard substrate, and the material thereof may be glass, tempered glass, sapphire glass, ceramic or other suitable materials, and the material of the flexible substrate may be selected from polyether sulfone (PES), polyethylene naphthalate (PEN), Polyethylene (PE), Polyimide (PI), polyvinyl chloride (PVC), polyethylene terephthalate (PET), etc., which may be appropriately changed according to actual design requirements, so the invention is not limited thereto. To understand the novel manufacturing method and structure design of the present invention, please refer to fig. 2A to fig. 2D, which are a flow chart of the manufacturing steps of the present invention, as shown in fig. 2A, the transparent substrate 10 further includes a light shielding layer 104, the light shielding layer 104 is disposed around the visible area 102, that is, an annular region is formed on the transparent substrate 10, the light shielding layer 104 of the present embodiment has sufficient Optical shielding property (i.e., OD, Optical sensitivity, value is above 3.0), the material of the light shielding layer 104 can be photoresist, ink, diamond-like carbon, ceramic, or a combination thereof, and the material and the shape of the light shielding layer 104 are not limited in the present invention, and can be appropriately changed according to the actual design requirements.
Next, as shown in fig. 2B, the conductive bonding pad layer 12 is attached to the periphery of the visible region 102 of the transparent substrate 10. The conductive bonding pad layer 12 is a conductive bonding pad double-sided tape, and the conductive bonding pad layer 12 includes a plurality of first conductive bonding pads 122. The conductive bonding pad layer 12 can be formed by a screen printing tool to fabricate a plurality of first conductive bonding pads 122 with single-sided conductive patterns in advance, and the first conductive bonding pads 122 are arranged at intervals. In detail, the invention firstly manufactures a single-sided conductive pattern with the existing specification (also called a public plate specification) on a conductive film, then coats the upper surface and the lower surface of the conductive film by using an adhesive, the adhesive on the upper surface covers the single-sided conductive pattern, and finally, a layer of separating film is respectively attached on the upper surface and the lower surface of the conductive film so as to finish the cuttable double-sided adhesive tape of the conductive bonding pad. Therefore, the conductive bonding pad layer 12 can be directly attached to the periphery of the visible region 102 by cutting off the separation film on the lower surface thereof, as long as the conductive bonding pad layer is cut according to the size of the transparent substrate 10 to be attached.
After the separation film on the upper surface of the conductive film is torn off, as shown in fig. 2C, the touch sensing layer 14 is attached to the visible region 102 of the transparent substrate 10, and a portion of the touch sensing layer 14 is attached to and in contact with the conductive bonding pad layer 12 to form an electrical connection, and the touch sensing layer 14 is a rectangular region surrounded and exposed by the light shielding layer 104. The touch sensing layer 14 is made of a transparent conductive material, and the material of the touch sensing layer can be gold, silver, copper, aluminum, indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, or other suitable oxides or stacked layers of at least two of the above-mentioned materials, but the invention is not limited thereto. The touch sensing layer 14 has a plurality of first axial sensing electrode units 142 and a plurality of second axial sensing electrode units 144, which are insulated from each other, and are attached to each other through a transparent insulating medium. In the present invention, the first axial sensing electrode units 142 and the second axial sensing electrode units 144 of the touch sensing layer 14 are manufactured by using the same mask tool, so that the cost of the tool can be greatly reduced. The first axial sensing electrode units 142 may be a series of sensing electrodes extending along the X-axis direction, and the second axial sensing electrode units 144 may be a series of sensing electrodes extending along the Y-axis direction. The first axial sensing electrode units 142 and the second axial sensing electrode units 144 are made of micro-conductive metal by forming electrode lines of the micro-conductive metal through photolithography, laser etching or screen printing. In detail, the touch sensing layer 14 may be designed to be a continuous repeating unit configuration, and may select a long-strip or diamond-shaped electrode line or electrode lines with various geometric shapes according to the requirement, which may be appropriately changed according to the actual design requirement, so the invention is not limited thereto. Each of the first axial sensing electrode units 142 has a plurality of first sensing electrodes as touch driving electrodes (Tx), each of the second axial sensing electrode units 144 has a plurality of second sensing electrodes as touch sensing electrodes (Rx), and the first sensing electrodes and the second sensing electrodes are insulated from each other and spaced apart from each other. It should be noted that the periphery of the visible region 102 of the transparent substrate 10 is generally used as a peripheral circuit region, and a conventional method is to design a plurality of traces to electrically connect the first sensing electrodes and the second sensing electrodes, but this manufacturing method needs a sufficient overlapping area and cannot be designed with any narrow sides, so that the space utilization rate of the touch region cannot be increased. Therefore, the present invention directly replaces the conventional trace design with the conductive bonding pad layer 12, and the design means of narrowing the edge by electrically connecting the plurality of first conductive bonding pads 122 to the plurality of first sensing electrodes and the plurality of second sensing electrodes (also known as PIN design in the actual industry at present) can make the design flexible and save the space of the trace design, and further make the 3D trace technology easier to be implemented on the Film (Film) process. When the driving circuit inputs a driving signal to the first sensing electrodes, a corresponding sensing signal is generated on each second sensing electrode. When touch occurs, the touch points generate phenomena such as electrode discharge and change of dielectric constant between electrodes, so that capacitance at the touch points also changes, and therefore when corresponding first sensing electrodes are scanned, induction signals on second sensing electrodes corresponding to the touch points also change, so that touch positions can be determined, and touch is achieved.
Next, as shown in fig. 2D, the flexible circuit board 16 is correspondingly attached to the conductive bonding pad layer 12 to form an electrical connection. Through the design of the conductive bonding pad double-sided tape, two sides of the conductive bonding pad double-sided tape can be respectively attached to one surface of the transparent substrate 10 and one surface of the flexible circuit board 16. The flexible printed circuit 16 includes a plurality of second conductive pads 162, and since the flexible printed circuit 16 is flexible, it has good bending property, and the position and size of the wire can be determined by design, so that the flexible printed circuit 16 can be integrated into the line width and distance that can be connected to a control board (not shown); each first conductive bonding pad 122 is correspondingly attached to each second conductive bonding pad 162 to directly form an electrical connection. Therefore, it is not necessary to additionally design a connection circuit with the flexible circuit board 16 on the touch sensing layer 14, and the frame width can be greatly reduced, so as to achieve the function requirement of narrow edge width. It should be noted that the lengths of the conductive bonding pad layer 12 and the flexible printed circuit 16 correspond to the size of the transparent substrate 10, in other words, the length of the flexible printed circuit 16 can be cut to correspond to the required size of the transparent substrate 10; the number of the first conductive bonding pads 122 and the second conductive bonding pads 162 on the conductive bonding pad layer 12 corresponds to the number of the first axial sensing electrode units 142 and the second axial sensing electrode units 144 of the touch sensing layer 14. In detail, the shapes and the number of the traces of the first axial sensing electrode units 142 and the second axial sensing electrode units 144 depend on the design of the conductive bonding pad layer 12 and the flexible circuit board 16, and the size of the touch sensing layer 14 can be freely tailored to the required size of the transparent substrate 10, which greatly facilitates and commercializes a small number of products with customized requirements.
Furthermore, the width of the frame designed by the present invention can meet the functional requirement of the narrow frame only by considering the space where the touch sensing layer 14 and the flexible circuit board 16 are respectively attached to the transparent substrate 10. Please refer to fig. 3A and fig. 3B, which are partial enlarged views of the narrow-bezel touch panel of the present invention. As shown in fig. 3A, each second conductive bonding pad 162 is correspondingly attached to each first conductive bonding pad 122 to directly form a conductive connection; as shown in fig. 3B, even though the second conductive bonding pads 162 are offset when attached to each of the first conductive bonding pads 122, the allowable deviation range is very large, and can be up to a millimeter (mm) range according to the design width of the electrode lines of the touch sensing layer 14. Since the second conductive bonding pads 162 and the first conductive bonding pads 122 are manufactured by using the existing specifications, the accuracy requirement when the second conductive bonding pads and the first conductive bonding pads are bonded to each other is low, the manufacturing yield can be greatly improved, and the manufacturing difficulty can be reduced.
In summary, the touch sensing layer is manufactured by using the same mask tool, and the size of the touch sensing layer can be freely cut to correspond to the size of the required transparent substrate (CG); moreover, the first axial sensing electrode units and the second axial sensing electrode units of the touch sensing layer can be assembled by using the same material and cutting the materials in different attaching directions and shapes, so that the touch sensing layer matched with the glass substrate can be manufactured by using the existing mask jig without mask development cost, and the manufacturing cost of the jig can be greatly reduced. Furthermore, the corresponding conductive bonding pad layer and the flexible circuit board are sequentially attached to the transparent substrate with the corresponding size, so that the required sensing size can be spliced and attached in a cutting mode, and the capacitive sensing device with various sizes can be matched. Aiming at the unique design that the conductive bonding pad layer is manufactured into the double-sided tape, the printed conductive bonding pad layer has the functions of bonding and conduction of the flexible circuit board, can freely cut the length and the width, does not need to develop a new jig, can actually increase the processing convenience and effectively reduce the cost.
Further, the present invention can use the design of the conductive bonding pad layer to omit the space configuration of the peripheral wiring design, thereby greatly increasing the space utilization rate and achieving the effect of extremely narrow frame. Aiming at the design that the conductive bonding pad layer is attached to the transparent substrate, the invention has the advantage that the rework can be carried out or the transparent substrate can be recycled. In addition, if the yield rate problem occurs in the manufacture of any conductive bonding pad layer, touch sensing layer or flexible circuit board, the flexible circuit board can be cut according to the bad position to be changed into a product with smaller size, so that the utilization rate and the application flexibility can be effectively increased, the effect of the product with single size capable of being freely shared is achieved, wider application is achieved by a simple processing mode, and the flexible circuit board has market competition advantages.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, all the equivalent changes or modifications according to the features and the spirit described in the scope of the application of the present invention should be included in the scope of the application of the present invention.
