[0078] According to various embodiments of the present disclosure, the first sensor layer 410 may include a plurality of first electrode patterns 412 arranged along a first direction (e.g., an X-axis direction). In addition, the first electrode patterns 412 may be electrically connected to each other so that a touch may be detected at a touched point. According to an embodiment of the present disclosure, the first electrode patterns 412 provided in a rhombus shape may be regularly arranged. However, this is merely an example, and embodiments of the present disclosure are not limited thereto. For example, the first electrode patterns may be arranged in a strip shape, such as Figure 5A , Figure 5B and Figure 5C as shown, and may also be configured into one of a variety of other shapes.

[0079] According to various embodiments of the present disclosure, the second sensor layer 420 may include a plurality of second electrode patterns 422 arranged in a second direction (e.g., a Y-axis direction) different from the first direction. In addition, the second electrode patterns 422 may be electrically connected to each other so that a touch may be detected at a touched point. According to an embodiment of the present disclosure, the second electrode pattern 422 may have the same shape as the first electrode pattern 412. However, this is merely an example, and embodiments of the present disclosure are not limited thereto. For example, the shape of the first electrode pattern 412 may be different from the shape of the second electrode pattern 422.

[0080] According to various embodiments of the present disclosure, the first electrode pattern 412 may have at least one opening 414 formed therein, and the second electrode pattern 422 may have at least one opening 424 formed therein. According to an embodiment of the present disclosure, the openings 414 and 424 formed in the first electrode pattern 412 and the second electrode pattern 422 may form a path along which the charging power generated by the wireless charging device 320 is transmitted. For example, the openings 414 formed in the first electrode pattern 412 and the openings 424 formed in the second electrode pattern 422 may be arranged in a rhombus shape, and the openings may be arranged in a 4×4 array, such as Figure 4A However, this is only an example, and the embodiments of the present disclosure are not limited thereto. The openings 414 and 424 formed in the first electrode pattern 412 and the second electrode pattern 422 may be arranged in one of various arrangements, and the shape of the openings, the size of the openings, and the number of the openings are not limited.

[0081] According to various embodiments of the present disclosure, at least one ground pattern 432 may be provided in the ground layer 430. The ground pattern 432 may include a plurality of first ground patterns 432-1 provided along a first direction (e.g., an X-axis direction) and a plurality of second ground patterns 432-3 provided along a second direction (e.g., a Y-axis direction) different from the first direction. However, this is merely an example, and embodiments of the present disclosure are not limited thereto.

[0082] According to an embodiment of the present disclosure, charging power generated by the wireless charging apparatus 320 may be transmitted using the space 432 - 5 configured between the ground patterns (eg, the ground patterns 432 - 1 and 432 - 3 ).

[0083] According to an embodiment of the present disclosure, the ground pattern 432 may be aligned with at least one of the first electrode pattern 412 or the second electrode pattern 422. For example, the first ground pattern 432-1 may be aligned with the first electrode pattern 412, and the second ground pattern 432-3 may be aligned with the second electrode pattern 422.

[0084] According to various embodiments of the present disclosure, the first ground pattern 432 - 1 and the second ground pattern 432 - 3 may be electrically connected to form a single ground pattern.

[0085] According to an embodiment of the present disclosure, the ground pattern 432 may have the same shape as the first electrode pattern 412 and the second electrode pattern 422. In addition, the position of the ground pattern 432 may correspond to the position of the first electrode pattern 412 and the position of the second electrode pattern 422. However, this is only an example, and the embodiments of the present disclosure are not limited thereto. For example, at least a portion of the ground pattern 432 may not correspond to the shape of the electrode pattern (e.g., the first electrode pattern 412 and the second electrode pattern 422) and the position of the electrode pattern (e.g., the first electrode pattern 412 and the second electrode pattern 422).

[0086] According to various embodiments of the present disclosure, at least one opening 434 may be formed in the ground layer 430 (e.g., the ground pattern 432). According to an embodiment of the present disclosure, the position of the opening 434 formed in the ground layer 430 may correspond to the position of the opening 414 formed in the first electrode pattern 412 and the position of the opening 424 formed in the second electrode pattern 422.

[0087] According to various embodiments of the present disclosure, the touch panel 214 may be implemented as a stack of a first sensor layer 410, a second sensor layer 420, and a ground layer 430. Figure 4B As shown, through the first sensor layer 410 and the second sensor layer 420, the first electrode pattern 412 and the second electrode pattern 422 can be uniformly arranged on the front side of the touch panel 214. In addition, the openings 414, 424 and 434 formed in the first sensor layer 410, the second sensor layer 420 and the ground layer 420 can also be uniformly arranged on the front side of the touch panel 214. Via the openings 414, 424 and 434, the charging power can pass through the touch panel 214 without being blocked by the first sensor layer 410, the second sensor layer 420 or the ground layer 430. Therefore, the wireless charging efficiency of the wireless charging device 320 (or the electronic device 101) can be improved. In addition, as described above, the ground layer 430 can be aligned with at least one of the first electrode pattern or the second electrode pattern, so that the capacitance of the touch panel 214 can be prevented from being changed by the wireless charging device 320, as described below with reference to Fig. 6A and Figure 6B described.

[0088] Although the first electrode pattern 412, the second electrode pattern 422, and the ground pattern 432 of the touch panel 214 are shown to be formed in different layers, this is only an example, and the present disclosure is not limited thereto. For example, at least two of the first electrode pattern 412, the second electrode pattern 422, or the ground pattern 432 may be provided in the same layer. In addition, although at least one opening 414, 424, and 434 is shown to be formed in each of the first electrode pattern 412, the second electrode pattern 422, and the ground pattern 432 of the touch panel 214, at least one opening may be formed in at least one of the first electrode pattern 412, the second electrode pattern 422, or the ground pattern 432.

Figure 5B is a diagram 540 showing openings formed in a touch panel having a stripe-shaped electrode pattern according to an embodiment of the present disclosure. Figure 5C is a diagram 570 showing openings formed in a touch panel having a stripe-shaped electrode pattern according to an embodiment of the present disclosure.

[0090] refer to Figure 5A , with reference Figure 4A and Figure 4B Unlike the touch panel 214 described above, the touch panel 570 may be implemented as a stack of a first sensor layer 510, a second sensor layer 520, and a ground layer 530, wherein in the first sensor layer 510, a first electrode pattern having a strip shape is arranged along a first direction (e.g., an X-axis direction), and in the second sensor layer 520, a second electrode pattern having a strip shape is arranged along a second direction (e.g., a Y-axis direction). According to various embodiments of the present disclosure, the first sensor layer 510 (or the first electrode pattern) may include at least one opening 512, and the second sensor layer 520 (or the second electrode pattern) may include at least one opening 522. In addition, at least one opening 532 may be formed in the ground layer 530. According to an embodiment of the present disclosure, the position of the opening 532 formed in the ground layer 530 may correspond to the position of the opening 512 formed in the first sensor layer 510 and the position of the opening 522 formed in the second sensor layer 520. For example, at least one opening 512, 522, and 532 formed in the first sensor layer 510, the second sensor layer 520, or the ground layer 530 may be provided in a quadrilateral shape as shown. However, this is merely an example, and embodiments of the present disclosure are not limited thereto.

[0091] refer to Figure 5B, the touch panel may include circular openings 514, 524, and 534 formed in the first sensor layer 510, the second sensor layer 520, and the ground layer 530. In addition, the opening may be formed in one of various shapes, for example, a hexagonal shape, a triangular shape, etc. As another example, the opening formed in at least one of the first sensor layer 510, the second sensor layer 520, and the ground layer 530 may have a shape different from that of the opening formed in the other layer. For example, the respective openings in the first sensor layer 510 and the second sensor layer 520 may be different from each other. As another example, a plurality of openings having different shapes may be formed in at least one of the first sensor layer 510, the second sensor layer 520, and the ground layer 530.

[0092] refer to Figure 5C In the ground layer 530 of the touch panel, first type openings 516 and 526 (e.g., circular openings) corresponding to the shapes of the openings in the first sensor layer 510 and the second sensor layer 520 may be included, and second type openings 536 (e.g., quadrilateral openings) whose shapes are different from those of the first type openings may be included.

[0093] Fig. 6A is a graph showing measurement values ​​610 and 620 associated with capacitance of a general touch panel according to an embodiment of the present disclosure. Figure 6B is a graph showing measurement values ​​630 and 640 related to capacitance of a touch panel according to an embodiment of the present disclosure.

[0094] refer to Fig. 6A Table 610 lists the values ​​obtained by performing digital conversion on the initial capacitance of a general touch panel, wherein the capacitance values ​​measured at each set of coordinates may be similar to each other. More specifically, the standard deviation of the initial capacitance values ​​at each coordinate may be approximately 33.28141358.

[0095] In addition, Table 620 lists the values ​​obtained by digitally converting the initial capacitance of the touch panel in a state where the wireless charging device 320 is disposed under the touch panel and no ground layer is formed. Compared with Table 610, Table 620 shows that the change in capacitance occurs at some coordinates 622 of the touch panel. More specifically, the standard deviation associated with the initial capacitance at each coordinate may increase to about 642.4766106. The charging power generated by the conductive charging coil disposed under the touch panel is blocked by the touch panel, so the capacitance at some coordinates of the touch panel may be changed.

[0096] refer to Figure 6B, Table 630 lists values ​​obtained by digitally converting initial capacitance of a touch panel provided with at least one opening and a ground layer, and the capacitance values ​​measured at each set of coordinates may be similar to the capacitance values ​​listed in Table 610. More specifically, the standard deviation of the initial capacitance values ​​at each coordinate may be approximately 30.25583053, which may be slightly lower than the values ​​obtained by digitally converting the capacitance of a general touch panel in Table 610. In general, a touch panel with low capacitance may show high detection performance. Due to the inclusion of the opening and the ground layer of the touch panel, the detection performance of the touch panel may be improved.

[0097] In addition, table 640 lists values ​​obtained by performing digital conversion on the initial capacitance of the touch panel when the wireless charging device is set under the touch panel, and the change in capacitance may not be obvious compared to table 630. More specifically, at coordinate 642 (ie, Fig. 6A The standard deviation of the initial capacitance value at the coordinates of the capacitance change shown in the graph 622 of FIG. 624 may be about 33.36133702. The charging power generated by the conductive charging coil disposed under the touch panel is not blocked by the touch panel, so the capacitance at some coordinates of the touch panel may not change.
