Touch panel

The present invention relates to a touch panel, and more particularly to a single-layer electrode type touch panel.

Conventional capacitive touch panels are typically constructed using a plurality of touch panels in a single or double layer configuration. Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a capacitive touch panel 100 constructed in a single layer structure. The touch panel 100 includes a substrate 110 and a single-layer electrode layer 120. The electrode layer 120 includes a plurality of sensing units G100, and each sensing unit G100 includes an electrode 122 and an electrode 124. In order to perform touch detection on the touch panel 100, the capacitive touch panel 100 provides a plurality of channels E1~E8 and F1~F8, wherein the channels E1~E8 are each formed by a triangular electrode 122, and the channels F1~F8 are respectively It is composed of triangular electrodes 124. That is, each sensing unit G100 corresponds to one of the channels E1 to E8 and one of the channels F1 to F8. In a single sensing unit G100, the electrodes 122 and the electrodes 124 are arranged as right-angled triangles of the same area, but the oblique sides of the two triangles are adjacent and arranged upside down. The width of the electrode 122 is reduced by the side S102 along the second direction D2 toward the side S104, and the width of the electrode 124 is reduced by the side S104 along the second direction D2 toward the side S102. Less. In this way, each channel E1~E8 can obtain a sensing signal in response to the user touching the area of the electrode 122 and each channel F1~F8 can obtain a sensing signal in response to the area touched by the user on the electrode 124. The touch panel 100 can determine the position touched by the user according to the sensing signal obtained by one of the channels E1 to E8 and one of the channels F1 to F8.

For example, FIG. 2 is a schematic diagram of a sensing signal of the touch panel 100. please Referring to FIG. 1 and FIG. 2 simultaneously, when the user touches the touch point T1, the channels E5~E7 and the channels F5~F7 receive the signals SE5~SE7 and SF5~SF6. As such, the touch panel 100 determines that the touch point T1 is located between the channel E6 and the channel F6. When the user touches the touch point T2, the channels E6~E8 and the channels F7~F8 receive the signals SE6~SE8 and SF7~SF8. As such, the touch panel 100 determines that the touch point T2 is located between the channel E7 and the channel F8. When the user touches the touch point T3, the channels E7~E8 and the channel F8 receive the signals SE7~SE8 and SF8. As such, the touch panel 100 determines that the touch point T3 is located in the channel E8 and not in the channels F1 to F8. In this way, if the user wants to perform a touch operation along the track T, the touch panel 100 calculates a track T', wherein the track T' is offset at the end, which may also be referred to as a tail-flick phenomenon. Therefore, the touch panel 100 has a problem that the sensing accuracy is not good, and in particular, the sensing accuracy at the edge is often not correctly judged.

In other words, the entire sensing unit has a plurality of repeating units 10 arranged in series, and the plurality of first electrodes 12 may be arranged in a zigzag shape, or may be a fork-shaped, comb-shaped or finger-shaped electrode. Similarly, the plurality of second electrodes 14 may also be arranged in a zigzag shape, but may also be a fork-shaped, comb-shaped or finger-shaped electrode.

A gap is formed between the first electrode 22 and the second electrode 24 at the boundary of an inverted oblique V-shaped profile or even a space.

Please refer to FIG. 5, which is a schematic diagram of a repeating unit 30 in accordance with another embodiment. The repeating unit 30 includes a first electrode 32 and a second electrode 34, wherein the first electrode 32 and the second electrode 34 are electrically independent of each other and are respectively connected to different channels. That is to say, the repeating unit 30 also corresponds to two channels in pairs. In addition, the first electrode 32 includes two first branch regions 32A and one first branch region 32B, and the second electrode 34 includes two second branch regions 34A. Here, the first branch regions 32A and 32B and the second branch region 34A each have a pointed structure, wherein the two first branch regions 32A are respectively partially pointed structures, and the first branch regions 32B and The two second branch regions 34A are respectively a complete pointed structure. The partial pointed structure and the complete pointed structure may be referred to the description of the foregoing embodiments without further elaboration. From another perspective, the two first branch regions 32A each have a right triangle profile, and the first branch region 32B and the two second branch regions 34A each have a non-orthogonal triangle profile.

The first branch region 32A having a partial pointed structure is located at the repeating unit 30 The two branches on the first direction D1 and the first branch region 32B having the complete pointed structure are located between the two first branch regions 32A. Meanwhile, each of the second branch regions 34A (having a complete pointed structure, respectively) is located between adjacent ones of the first branch regions 32A and 32B, that is, the first branch regions 32A and 32B and the second branch region 34A One direction D1 is alternately arranged. In this way, a gap between the first electrode 32 and the second electrode 34 is a boundary of a double V-shaped profile V2 or even a space, and the repeating unit 30 is along a center line M2 parallel to the second direction D2. Symmetrical structure. In Fig. 5, the complete pointed structure is an isosceles triangle, but is not limited thereto. In FIG. 6, the repeating unit 40 includes a first electrode 42 and a second electrode 44, wherein the first electrode 42 includes two first branch regions 42A and one first branch region 42B, and the second electrode 44 includes two Two branch areas 44A.

In the embodiment of Figures 3 and 4, the first has a complete pointed structure The number of branch regions is 0, and the number of second branch regions having a complete pointed structure is 1. In the embodiment of Figures 5 and 6, the number of first branch regions having a full pointed structure is one, and the number of second branch regions having a complete pointed structure is two. It may be noted that the embodiment of Figures 5 and 6 differs from the embodiment of Figures 3 and 4 primarily in the number of first branch regions having a complete pointed configuration and second branch regions having a complete pointed configuration. In other embodiments, the number of first branch regions having a complete pointed structure and the second branch regions having a complete pointed structure may be increased according to different designs, such as 3 or more.

It should be noted that the common point of the embodiments of FIG. 3 to FIG. 6 is that Both edges of the complex unit in the first direction D1 are branch regions of the same electrode (the first electrode in the above embodiment). Rather, the two sides of each repeating unit are differently branched regions of different electrodes. In addition, the first branching region of the repeating unit comprises two partial pointed structures respectively disposed on both sides of the repeating unit, and a certain number of complete pointed structures disposed between the two partial pointed structures And the second branch region includes the same number of complete pointed structures disposed between the plurality of first branch regions, wherein the number is a positive integer.

Furthermore, the second branch regions (such as the aforementioned 32A or 42A) are all complete pointed structures and the number is Zi, where Zi can be any positive integer.

In the foregoing embodiments, the repeating units are all connected only to a single pair of channels, which are defined herein as a first type of repeating unit for convenience of explanation. In addition, a structure that is more defined to be connected to a pair of channels is defined as a basic unit. It can be observed from Fig. 3 to Fig. 6 that since the repeating units 10 to 40 belong to the first type of repeating unit, each repeating unit itself is composed of one basic unit.

It can be noted that in the first type of repeating unit of FIGS. 3 to 6, each basic unit equivalently has a complete sharp structure of Xi group, where Xi=Pi and Pi is a positive integer. More specifically, in the basic unit of the first type of repeating unit, the first electrode has Xi+1 first branch regions, and among them, (Xi-1) first branch regions are completely pointed structures (such as the foregoing a branch region 32B or 42B), and two first branch regions are respectively located at two different sides of the base unit and are partially pointed structures (such as the aforementioned first branch regions 12A, 22A, 32A or 42A), but these two The partial pointed structures on the sides can be equivalently combined to form a complete pointed structure. Therefore, in a basic unit, the first electrode equivalently has ((Xi-1)+1)=Xi complete pointed structures. Furthermore, the second electrode of the basic unit of the first type of repeating unit has Xi second branch regions, each Both are a complete pointed structure (such as the first branch region 14A, 24A, 34A or 44A described above), so the number of second branch regions of the complete pointed structure is Xi. In other words, the second electrode also has Xi full pointed structures. In summary, in the basic unit of the first type of repeating unit, the first electrode equivalently has Xi complete pointed structures, and the second electrode actually has Xi complete pointed structures, so the basic unit of the first type of repeating unit Equivalently has a complete pointed structure of the Xi group.

Therefore, the repeating unit 10 or the basic unit of FIG. 3 has one set of equivalents. The indented structure (the first branching region 12A of the two partial pointed structures and the second branched region 14A of a complete pointed pattern form a group). The repeating unit 20 or the basic unit of Fig. 4 also has a complete set of pointed structures equivalently, and the repeating unit 30 of Fig. 5 and the repeating unit 40 or the basic unit of Fig. 6 respectively have two sets of complete pointed structures. In other embodiments, each of the basic units of the first type of repeating unit may equivalently have three sets of complete pointed structures, four sets of complete pointed structures, or more sets of complete pointed structures.

In other words, in the i-th repeating unit, the number of the first branch regions having the complete pointed structure is (Zi-1), and the number of the partial pointed structures is 2 (both sides of the same repeating unit are respectively located). Furthermore, the second branch regions are all complete pointed structures and the number is Zi, where Zi can be any positive integer.
