In addition, the sensing unit 20 includes at least a first sensing unit 21 and a second sensing unit 22, wherein the second bridge electrode 32B of the first sensing unit 21 has a first long direction L1 and a second sensing unit. The second bridge electrode 32B has a second longitudinal direction L2, and the first longitudinal direction L1, the second longitudinal direction L2, the first direction D1 and the second direction D2 are different directions, respectively. In this embodiment, the first sensing unit 21 and the second sensing unit 22 are alternately arranged in the first direction D1, and the first sensing unit 21 and the second sensing unit 22 are in the second direction D2. Alternately arranged, but not limited to this.

The capacitive touch panel 1 is usually integrated with the display panel to form a touch display panel. The signal lines on the display panel, such as the gate lines (or scan lines) and the data lines, respectively follow the first direction D1 and the second direction. The direction D2 is set, so it is easier to generate moiré due to optical interference. The second bridge electrode 32B of the capacitive touch panel 1 of the present embodiment is disposed obliquely (that is, the second bridge electrode 32B is not parallel to the first direction D1 and the second direction D2 and is not perpendicular), which can effectively avoid The second bridging electrode 32B generates a moiré due to optical interference. In addition, the second bridging electrode 32B of the capacitive touch panel 1 of the present embodiment has two or more different oblique arrangement directions, that is, a part of the second bridging electrode 32B has a first long direction L1, and the other part has The second bridging electrode 32B has the second long direction L2, so that even if the alignment error occurs when the capacitive touch panel 1 and the display panel are assembled, the generation of the moiré can be effectively suppressed. Further, if the second direction D2 is a reference line, the slope of the first long direction L1 of the second bridge electrode 32B of the first sensing unit 21 may be a positive value ("+"), and the second The slope of the second long direction L2 of the second bridge electrode 32B of the sensing unit 22 may be a negative value ("-").

In this embodiment, the absolute value of the first azimuth angle A1 is substantially equal to the absolute value of the second azimuth angle A2, that is, if the first azimuth angle A1 is 30°, the second azimuth angle A2 is -30°; The first azimuth angle A1 is 45°, then the second azimuth angle A2 is -45°, and so on, but not limited thereto.

Please refer to Figure 3. Figure 3 depicts the experimental results of the optical performance of bridging electrodes having different shapes and different azimuthal angles. As shown in Fig. 3, when the bridge electrode is rectangular, if its azimuth angle is 0° (sample 6) and 90° (sample 7), it has a visible visible pattern and causes poor optical performance. When the bridge electrode is rectangular, if it has an azimuth angle of 30° (sample 4) and 45° (sample 5), it has almost invisible moiré and has good optical performance. In addition, when the bridge electrode is "ㄑ" shaped (bent or V-shaped) (sample 1), semi-circular (sample 2) and curved (sample 3), it still has an identifiable pattern Optical performance is ordinary. As can be seen from the experimental results in FIG. 3, when the bridge electrodes are rectangular and their longitudinal directions are obliquely disposed, it is possible to effectively improve the embossing and greatly enhance the optical performance. It should be noted that when the capacitive touch panel is integrated with the display panel, whether all the secondary pixels of the display panel are displayed in a bright state (for example, when the red, green, and blue sub-pixels are displayed in a bright state) Or when only a part of the pixels display a bright state and a part of the pixels display a dark state (for example, when the green sub-pixel displays a bright state and the red and blue sub-pixels display a dark state), sample 4 and sample 5 Because the bridge electrodes are arranged obliquely, they all have almost invisible moiré and have good optical performance. In contrast, the bridge electrodes of other samples show bright state only in partial sub-pixels and dark pixels in partial sub-pixels. When the state (for example, the green sub-pixel display is bright and the red and blue sub-pixels are displayed in the dark state), it is difficult to observe the moiré, but when all the sub-pixels are all displayed in bright state (for example, red, green, and blue times) When the pixels are displayed in a bright state, they will have a visible visible pattern and cause poor optical performance.

Please refer to Figure 4. FIG. 4 is a schematic diagram of a capacitive touch panel according to a variation of the first embodiment of the present invention. As shown in FIG. 4, in the capacitive touch panel 1' of the modified embodiment, the adjacent two sensing units 20 may share the first sensing pad 31P or the second sensing pad 32P.

One of the two second sensing pads 32P of any one of the sensing units 20 may also be two second sensings of another sensing unit 20 adjacent in the second direction D2 One of the pads 32P. Unlike the first embodiment, in the present modified embodiment, the long direction of the first bridge electrode 31B is not parallel and is not perpendicular to the first direction D1 and the second direction D2. To be precise, the first bridge electrode 31B of the first sensing unit 21 has a first long direction N1, and the first bridge electrode 31B of the second sensing unit 22 has a second long direction N2, wherein the first long direction N1 It is not parallel to the second long direction N2 and is not perpendicular to the first direction D1 and the second direction D2, that is, the first long direction N1 is not parallel and is not perpendicular to the first direction D1 and the second direction D2, and The two long directions N2 are not parallel and are not perpendicular to the first direction D1 and the second direction D2. For example, the first long direction N1 of the first bridging electrode 31B of the first sensing unit 21 may be substantially perpendicular to the first long direction L1 of the second bridging electrode 32B of the first sensing unit 21, and the second sense The second long direction N2 of the first bridging electrode 31B of the measuring unit 22 and the second long direction L2 of the second bridging electrode 32B of the second sensing unit 22 are substantially perpendicular, thereby increasing the first of the second bridging electrode 32B The adjustment range of the azimuth angle A1 and the second azimuth angle A2, that is, if the angles of the first azimuth angle A1 and the second azimuth angle A2 are larger, the first long direction N1 and the second direction of the first bridge electrode 31B are adjusted. In the long direction N2, the second bridge electrode 31B can be effectively connected to the second sensing pad 32P without extending the second bridge electrode 31B, so that the visibility of the second bridge electrode 31B can be reduced. In addition, due to the first long direction N1 and the second long The directions N2 are not parallel and are not perpendicular to the first direction D1 and the second direction D2, and the pattern of the first sensing pad 31P and/or the pattern of the second sensing pad 32P can be appropriately adjusted. For example, in the embodiment, the shape of the first sensing pad 31P is substantially rhombic or rectangular, and the shape of the second sensing pad 32P is substantially rhombic or rectangular, but is not limited thereto. For example, the shape of the first sensing pad 31P and the second sensing pad 32P may be a circle, a semicircle, or a polygon such as a triangle, a pentagon, a hexagon, or the like. In this embodiment, the adjacent first sensing pads 31P and the second sensing pads 32P have substantially the same pitch, but are not limited thereto. In other variant embodiments, in order to make the first long direction N1 and the second long direction N2 are not parallel and not perpendicular to the first direction D1 and the second direction D2, the pattern of the first sensing pad 31P may be Or the pattern of the second sensing pad 32P is moderately adjusted such that the adjacent first sensing pad 31P and the second sensing pad 32P have substantially different pitches.
