Schematic diagram of the cross-sectional structure taken along section line I-I'. As shown in FIG. 1 to FIG. 3 , the touch panel 10 defines a visible area 101 and a non-visible area 102 surrounding the visible area 101 , and includes a cover 11 , a shielding layer 12 , a touch sensing structure 13 , and a first Decorative layer 14. The cover plate 11 can be a tempered glass plate or a plasticized film, the upper surface of which can be touched by the user, and the lower surface can be provided with other components constituting the touch panel as described below.

The shielding layer 12 can be located between the cover 11 and the touch sensing structure 13 in the non-visible area 102. In this embodiment, the shielding layer 12 can be located on the lower surface of the cover 11 in the non-visible area 102, wherein the shielding layer The material of 12 is an opaque material, such as a colored ink, which acts to shield other circuit components located in the non-visible area to ensure the appearance of the product. The mask layer 12 is provided with a pattern 121, which is a hollow pattern formed on the shielding layer 12 by etching, which may be a touch function button graphic located in the non-visible area, a brand identity of the product or other decorative patterns. In this embodiment, the pattern 121 is a touch function button graphic located in the non-visible area.

The touch sensing structure 13 can be located on the lower surface of the shielding layer 12 and corresponding to the pattern 121. The touch sensing structure 13 can be disposed under the cover 101 in the visible area 101, for example, can be directly disposed on the cover. The lower surface of the panel 11 , but in other embodiments, other auxiliary component layers may be disposed between the touch sensing structure 13 and the cover 11 in the visible region 101 , which is not limited herein.

The first decorative layer 14 is located in the non-visible area 102 and may be located on the lower surface of the touch sensing structure 13 and corresponding to the pattern 121 in the non-visible area 102, so that the hollow portion of the pattern 121 displays a corresponding color effect.

In this embodiment, as shown in FIG. 1 , the touch sensing structure 13 includes a plurality of first axial electrodes 131 arranged in parallel along a first direction (the X axis in the embodiment), and a plurality of strips The second axial electrodes 132 are arranged in parallel along a second direction (the Y-axis in this embodiment). The second axial electrode 132 and the first axial electrode 131 are insulated from each other, and the second axial electrode 132 includes a plurality of conductive units 1321 and a plurality of connecting lines 1322 electrically connecting the two adjacent conductive units 1321, wherein the first The axial electrode 131 and the conductive unit 1321 are in the same plane, and an insulating layer 133 exists between the first axial electrode 131 and the connecting line 1322.

One end of each conductive line 134 is electrically connected to the first axial electrode 131 and the second axial electrode 132, and the other end is connected to the outside. A processor (not shown) is coupled to receive and analyze the touch signals received from the touch panel. In this embodiment, the touch sensing structure 13 is a single layer touch electrode junction. The first axial electrode 131 and the conductive unit 1322 are in the same level plane. This structure can reduce the thickness of the touch sensing structure 13 , but it is worth noting that the structure of the touch sensing structure 13 is not limited. Thus, it can be a two-layer or multi-layer touch electrode structure, that is, two axial electrodes are separated into different planes by a full-surface insulating layer.

In this embodiment, the first axial electrode 131 and the second axial electrode 132 included in the touch sensing structure 13 are mainly composed of a transparent conductive material, for example, indium tin oxide (ITO), indium oxide.

It is noted that the first decorative layer 14 can be a single layer structure or a multilayer structure to be combined into a variety of different colors. Since the first decorative layer 14 is disposed on the lower surface of the touch sensing structure 13 , the cover 11 has only the shielding layer 12 on the lower surface of the non-visible area 102 before the touch sensing structure 13 is formed. There is a small difference in height generated at the interface between the visible area 101 and the non-visible area 102, and the touch sensing structure 13 It can be formed on a relatively gentle surface, which can reduce the possibility of flaws in the formation of the touch sensing structure 13.

It should be noted that when the button module of the touch panel 10 needs to have a touch function, the touch sensing structure 13 will extend from the visible area 101 to the area of the pattern 121 located in the non-visible area 102 to provide a touch.

The touch sensing structure 13 is disposed in the region of the pattern 121 and is located between the first decorative layer 14 and the shielding layer 12. Since the electrodes of the touch sensing structure 13 are mainly composed of transparent conductive materials, they are not shielded. Light from the lower source. In addition, if the pattern 121 is only used as a brand logo or other decorative pattern of the product, the material that extends the touch sensing structure 13 to the area where the pattern 121 is located may be omitted.

It should be noted that, in this embodiment, the shielding layer 12 is located between the cover 11 and the touch sensing structure 13, and those skilled in the art can understand that the position of the shielding layer 12 is not limited thereto. In other embodiments of the present invention, the shielding layer 12 can be located under the touch sensing structure 13 , in other words, the visible area of the touch panel and the non-visible area touch sensing structure 13 can be directly fabricated on the cover 11 The lower surface, that is, the touch sensing structure 13 is located between the cover 11 and the shielding layer 12 . In this embodiment, it should be specifically noted that the touch sensing structure 13 is not completely located on the cover 11 and the shielding layer 12 . In other words, the plurality of conductive lines 134 of the touch sensing structure 13 are located on the lower surface of the shielding layer 12 and are connected to the first axial electrodes 131 and the second axial electrodes 132 through other electrical connections. For example, the connection is made through a bridging structure or at a corresponding location in the obscuring layer 12. That is, the shielding layer 12 and the touch sensing structure 13 may be integrated components. Therefore, the relative position between the cover 11 and the decorative layer 14 may not be fixed, and the shielding layer 12 may be touched first.
