It should be noted that the configuration relationship between the sensing pattern 110 and the conductive circuit pattern 120 shown in FIG. 8 is not shown in accordance with the actual scale or quantity, and will be described first.

The substrate 102 includes a touch area 108 and a peripheral area 109 . Both the sensing pattern 110 and the conductive circuit pattern 120 are disposed on the substrate 102 , wherein the sensing pattern 110 is located on the touch area 108 , and the conductive circuit pattern 120 is located on the touch area 108 and the peripheral area 109 .

The sensing pattern 110 includes a sensing main unit 111 and a sensing sub-unit 115 . The main sensing unit 111 includes a main electrode 112 and a plurality of finger electrodes 113 , wherein the finger electrodes 113 extend from the main electrode 112 and are regularly arranged at intervals. The material of the main sensing unit 111 is a highly penetrating conductive material.

The sensing subunit 115 includes a pair of rectangular electrodes 116 and a connecting portion 117 . The paired rectangular electrodes 116 are arranged parallel to each other, and are connected through the connecting portion 117 arranged between the rectangular electrodes 116 .

The single-layer touch panel 100 also includes a separation line 130, and the separation line 130 defines a first area 132 and a second area 134 on the substrate 102, wherein the distance between the first area 132 and the control unit 104 is greater than that of the second area. The distance between the area 134 and the control unit 104 . And in this embodiment, the shape and material of the sensing sub-units 115 within the range of the first region 132 are different from those of the sensing sub-units 115 within the range of the second region 134 .

More specifically, in the first region 132 , the material of the rectangular electrode 116 and the connecting portion 117 is a low-penetration conductive material and both are metal grids. In the second region 134 , the material of the rectangular electrode 116 and the connecting portion 117 is a highly penetrating conductive material.

However, it should be understood that the position of the dividing line 130 shown in FIG. Therefore, those with ordinary knowledge in the technical field of the present invention can flexibly select the position of the separation line 130 according to actual needs.

The conductive circuit pattern 120 is used to connect the sensing sub-unit 115 and the control unit 104 . According to the sensing sub-units 115 connected to different regions, the conductive circuit pattern 120 can also be composed of different materials.

Specifically, the material of the conductive circuit pattern 120 connected to the sensing subunit 115 in the first region 132 is a low-penetration conductive material. The material of the conductive circuit pattern 120 connected to the sensing sub-unit 115 in the second region 134 is a high-penetration conductive material.

The difference between this embodiment and the seventh embodiment is that the sensing sub-unit 115 has two different forms and configurations, and the sensing sub-unit 115 includes two forms of transparent electrodes and metal grids. On the substrate 102, the sensing sub-unit 115 on the side close to the control unit 104 (that is, located in the second region 134) and the corresponding connected conductive circuit pattern 120 are made of highly penetrating conductive material, and the opposite side (that is, located in the first region 134) The sensing sub-unit 115 in the region 132) and the corresponding connected conductive circuit pattern 120 are low-penetration conductive materials.

Compared with the seventh embodiment, the configuration method of this embodiment further reduces the chance of the Murray effect due to the reduction of the ratio of metal grids or lines, and because the configuration position of the highly penetrating conductive material is close to the control unit 104, so the transmission distance is relatively short, and the requirements for impedance are not high.

Generally speaking, the single-layer touch panel 100 of the present invention is a mixed material configuration, wherein the materials of the sensing pattern 110 and the conductive circuit pattern 120 include two types of high-penetration conductive materials and low-penetration conductive materials.

In addition, the area of the highly penetrating conductive material accounts for about 50%-90% of the area of the entire substrate 102 , preferably between 60%-70%. The area percentage of the low-penetration conductive material accounts for about 1%-20% of the entire substrate 102 , preferably between 3%-10%.

In one embodiment, the single-layer touch panel 100 of the present invention can be fabricated through yellow light lithography. Specifically, the materials of the sensing patterns 110 and the conductive circuit patterns 120 of the single-layer touch panel 100 of the present invention can be classified into two types: high-penetration conductive materials and low-penetration conductive materials. The high-transmittance conductive material can be fabricated on the substrate 102 through a yellow light lithography process, and the low-penetration conductive material can be fabricated on the same substrate 102 through another yellow light lithography process, and the high-penetration conductive material At the connection between the material and the low-penetration conductive material, the two materials will partially overlap to ensure the reliability of the electrical connection. Generally speaking, since the process temperature of the high-penetration conductive material is relatively high, the high-penetration conductive material is formed on the substrate 102 first, and then the low-penetration conductive material is fabricated.

In yet another embodiment, one of the high-penetration conductive material and the low-penetration conductive material can be fabricated on the substrate 102 through a yellow light lithography process, and the high-penetration conductive material and the low-penetration conductive material The other one is formed on the substrate 102 by transfer printing. Similarly, in order to ensure the reliability of the electrical connection, at the junction of the high-penetration conductive material and the low-penetration conductive material, the two materials will partially overlap.

In another embodiment, the conductive material with high penetrability and the conductive material with low penetrability can be fabricated on the two substrates 102 through lithography, screen printing or other feasible processes, and then the two substrates 102 to obtain a single-layer touch panel 100 of mixed materials. Similarly, in order to ensure the reliability of the electrical connection, at the junction of the high-penetration conductive material and the low-penetration conductive material, the two materials will partially overlap.

The conductive material pattern 146. The same or different processes may be used for forming the high-penetration conductive material pattern 144 and the low-penetration conductive material pattern 146 . Next, attach the first substrate 140 to the second substrate 142, so that the high-penetration conductive material pattern 144 and the low-penetration conductive material pattern 146 are both arranged between the first substrate 140 and the second substrate 142, so that The structure of the single-layer touch panel 100 using composite materials of the present invention is completed, as shown in FIG. 9B .
