Examples of cover members may include a glass plate, a fiberglass reinforced plastic (FRP) plate, a polyvinyl fluoride (PVF) film, a polyester film, a polyester film, or an acrylic film. However, this is merely an example, and the present disclosure is not limited thereto. For example, the cover member may be made of various materials that do not hinder wireless charging power transmission. According to another embodiment of the present disclosure, an insulating layer may be additionally included between the touch pad 214 and the wireless charging unit 320, and the touch pad 214 and the wireless charging unit 320 may be electrically connected through the insulating layer.

[0079] In addition, as described above, the touch panel device may have a structure in which the touch panel 214 and the wireless charging unit 320 are separated from each other. However, this is only an example, and the present disclosure is not limited thereto. For example, the touch panel device may have a structure in which the wireless charging unit 320 and the touch panel 214 are integrated into one body.

[0080] Figure 4A A configuration of a touch panel according to an embodiment of the present disclosure is shown. Figure 4B The diagram shows a stacked state of a first sensor layer, a second sensor layer, and a ground layer of a touch panel according to an embodiment of the present disclosure.

[0081] Reference Figure 4A , the touch panel 214 may include: a first sensor layer 410 having a first electrode pattern, a second sensor layer 420 having a second electrode pattern, and a ground layer 430 .

[0082] According to various embodiments of the present disclosure, the first sensor layer 410 may include a plurality of first electrode patterns 412 formed in a first direction (e.g., an X-axis direction). The first electrode patterns 412 may be electrically connected to each other to enable detection of a touch point. According to one embodiment of the present disclosure, the first electrode patterns 412 may be regularly formed into a rhombus. However, this is only an example, and the present disclosure is not limited thereto. As will be described later with reference to FIG. 5A to FIG. 5C As described above, the first electrode pattern may be formed in a stripe shape, or may be formed in various shapes.

[0083] According to various embodiments of the present disclosure, the second sensor layer 420 may include a plurality of second electrode patterns 422 formed in a second direction (e.g., a Y-axis direction) different from the first direction. The second electrode patterns 422 may also be electrically connected to each other to enable detection of a touch point. According to one 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 the present disclosure is not limited thereto. For example, the shape of the second electrode pattern 422 may not correspond to the shape of the first electrode pattern 412.

[0084] According to one embodiment of the present disclosure, each first electrode pattern 412 may have one or more openings 414, and each second electrode pattern 422 may also have one or more openings 424. According to one 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 for transmitting the charging power generated by the wireless charging unit 320. For example, Figure 4A As shown, the openings 414 and 424 formed in each first electrode pattern 412 and each second electrode pattern 422 may have a 4×4 arrangement and may have a rhombus shape. However, this is only an example, and the present disclosure is not limited thereto. For example, the openings 414 and 424 formed in the first electrode pattern 412 and the second electrode pattern 422 may have a variety of arrangements, and the shape, size, and number of the openings are also not limited.

[0085] According to various embodiments of the present disclosure, one or more ground patterns 432 may be formed at the ground layer 430. The ground pattern 432 may include a plurality of first ground patterns 432-1 formed in a first direction (e.g., an X-axis direction), and a plurality of second ground patterns 432-3 formed in a second direction (e.g., a Y-axis direction) different from the first direction. However, this is merely an example, and the present disclosure is not limited thereto. According to one embodiment of the present disclosure, the charging power generated by the wireless charging unit 320 may be transmitted using a space 432-5 formed between the ground patterns (e.g., reference numerals 432-1 and 432-3).

[0086] 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.

[0087] 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 each other to form one ground pattern.

[0088] According to various embodiments 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. 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 present disclosure is not limited thereto. For example, the shape and position of at least some of the ground patterns 432 may not correspond to the shape and position of the electrode pattern (e.g., the first electrode pattern 412 and the second electrode pattern 422).

[0089] According to various embodiments of the present disclosure, one or more openings 434 may be formed in the ground layer 430 (e.g., the ground pattern 432). According to one embodiment of the present disclosure, the positions of the openings 434 formed in the ground layer 430 may correspond to the positions of the openings 414 formed in the first electrode pattern 412 and the positions of the openings 424 formed in the second electrode pattern 422.

[0090] According to various embodiments of the present disclosure, the touch panel 214 may be formed by stacking a first sensor layer 410 , a second sensor layer 420 , and a ground layer 430 on one another.

[0091] Reference Figure 4B , the first electrode pattern 412 and the second electrode pattern 422 may be uniformly formed on the front surface of the touch panel 214 through the first sensor layer 410 and the second sensor layer 420, and the openings 414, 424 and 434 may also be uniformly formed on the front surface of the touch panel 214 through the first sensor layer 410, the second sensor layer 420 and the ground layer 430. Due to the openings 414, 424 and 434, the charging power may pass through the touch panel 214 without being interrupted by the first sensor layer 410, the second sensor layer 420 and the ground layer 430, thereby improving the wireless charging efficiency of the wireless charging unit 320 (or the electronic device 101). In addition, as described above, the ground layer 430 may be aligned with at least one of the first electrode pattern or the second electrode pattern, so that the capacitance value of the touch panel 214 may be prevented from being changed by the wireless charging unit 320.

[0092] It has been described that the first electrode pattern 412, the second electrode pattern 422, and the ground pattern 432 of the first electrode pattern 412 are formed on different layers, respectively. However, this is only an example, and the present disclosure is not limited thereto. For example, at least one of the first electrode pattern 412, the second electrode pattern 422, or the ground pattern 432 may be formed on the same layer. In addition, it has been described that one or more openings 414, 424, and 434 are formed in the first electrode pattern 412, the second electrode pattern 422, and the ground pattern 432 of the touch panel 214, respectively. However, one or more openings may be formed in at least one of the first electrode pattern 412, the second electrode pattern 422, or the ground pattern 432.

Figure 5C is a diagram illustrating an opening formed in a touch panel having a stripe-shaped electrode pattern according to an embodiment of the present disclosure.

[0094] Reference Figure 5A ,and Figure 4A and 4B Unlike the touch panel 214 shown in the figure, the touch panel 500 may be formed by stacking a first sensor layer 510 having a strip-shaped first electrode pattern formed in a first direction (e.g., the X-axis direction), a second sensor layer 520 having a strip-shaped second electrode pattern formed in a second direction (e.g., the Y-axis direction), and a ground layer on top of each other. According to one embodiment of the present disclosure, the first sensor layer 510 (or the first electrode pattern) may include one or more openings 512, and the second sensor layer 520 (or the second electrode pattern) may include one or more openings 522. In addition, one or more openings 532 may be formed in the ground layer 530. According to one embodiment of the present disclosure, the positions of the openings 532 formed in the ground layer 530 may correspond to the positions of the openings 512 formed in the first sensor layer 510 and the positions of the openings 522 formed in the second sensor layer 520. For example, as Figure 5A As shown, one or more openings 512, 522, and 532 formed in the first sensor layer 510, the second sensor layer 520, and the ground layer 530 may have a quadrilateral shape. However, this is merely an example, and the present disclosure is not limited thereto.

[0095] Reference Figure 5B , the touch panel 540 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, respectively, and the openings may have various shapes, such as a hexagon or a triangle. In another example, the opening formed in at least one of the first sensor layer 510, the second sensor layer 520, or the ground layer 530 may have a shape different from the shapes of the openings formed in the remaining layers. The first sensor layer 510 may include an opening having a shape different from the shape of the opening included in the second sensor layer 520. In another example, a plurality of different openings may be formed in at least one of the first sensor layer 510, the second sensor layer 520, or the ground layer 530.

[0096] Reference Figure 5C , the ground layer 530 of the touch panel 570 may include: a first group of openings 516 and 526 (e.g., circular openings) whose shapes correspond to the shapes of the openings of the first sensor layer 510 and the second sensor layer 520; and a second group of openings 536 (e.g., quadrilateral openings) that are different in shape from the first group of openings.

[0097] Figure 6 is a diagram 600 showing an electronic device for providing a wireless charging function according to an embodiment of the present disclosure.

[0098] Reference Figure 6 , the electronic device 101 may include: a touch panel 214 , a wireless charging unit 320 (eg, a wireless charging coil 322 ), and a processor 120 .

[0099] According to various embodiments of the present disclosure, as described above with reference to Figure 3 As described, the touch panel 214 can detect a designated signal according to a touch of an input subject (or a body of an input subject) (e.g., a part of a body, an electronic pen, etc.), and can process an input of a position that the user desires to point to based at least in part on the detected signal. For example, the touch panel 214 can send information related to the coordinates of a touch point thereon (e.g., an X-axis coordinate and / or a Y-axis coordinate) to the processor 210.

[0100] According to various embodiments of the present disclosure, the processor 120 may determine the distribution of detection nodes of the touch panel 214 where capacitance changes have been detected, based at least in part on information provided from the touch panel 214. For example, the processor 120 may determine the capacitance standard deviation of the detection nodes (where capacitance changes have been detected). The standard deviation may be calculated by the capacitance calculator 602. For example, as described later with reference to Figure 8 As described, the capacitance calculator 602 may calculate the standard deviation based on the capacitance change calculated by comparing the capacitance before the touch input is detected with the capacitance when the touch input has been detected (or after the touch input is detected).

[0101] According to one embodiment of the present disclosure, the processor 120 may determine the input subject based on the calculated capacitance standard deviation. For example, the processor 120 may determine whether the input subject that has touched the touch panel 214 is a subject that requires a charging function or a subject that requires a touch function. For example, when the calculated standard deviation exceeds a pre-specified reference deviation range, the processor 120 may determine that a touch input has been performed by an input subject that requires a touch function (e.g., a finger, a palm, or an electronic pen). The reference deviation range may be a capacitance range that may be changed by a predetermined input subject that requires a touch function. In addition, when the calculated standard deviation does not exceed a predetermined reference deviation range, the processor 120 may determine that a touch input has been performed by an input subject that requires a charging function (e.g., an electronic device that supports a wireless charging function (e.g., a smartphone or a headset)).

[0102] According to one embodiment of the present disclosure, the processor 120 may control the wireless charging function based on the result of determining the input subject. For example, when it is determined that the input subject requiring the touch input function has performed a touch, the processor 120 may perform a touch detection function. For example, the touch detection function may be a mode for activating the touch panel 214 and deactivating the wireless charging unit 320. For example, the wireless charging unit 320 may be deactivated by the control of the charging controller 604.

[0103] According to one embodiment of the present disclosure, when it is determined that the input subject requiring the wireless charging function has performed a touch, the processor 120 may stop the touch detection function and may perform the charging function. For example, the processor 120 may perform a charging function of sending a specified signal (e.g., a ping signal) for determining the presence of a wireless power receiving unit (e.g., a charging power receiving coil) and identifying the wireless power receiving unit. For example, the wireless charging unit 320 may be activated by the control of the charging controller 604. In another example, the processor 120 may prevent unnecessary power consumption by deactivating the touch panel 214 when performing the charging function. In addition, when the processor 120 determines that there is no wireless power receiving unit or the wireless power receiving unit is not identified, the processor 120 may stop performing the charging function.

[0104] According to one embodiment of the present disclosure, the processor 120 may monitor the state of the input subject (e.g., the wireless power receiving unit) while executing the charging function. In addition, the processor 120 may control the operation of the wireless charging unit 320 based on the monitoring result. For example, the processor 120 may complete the execution of the wireless charging function when the wireless power receiving unit exceeds a specified distance from the touch panel 214 or when a signal notifying the completion of charging is received from the wireless power receiving unit. For example, the processor 120 may activate the touch panel 214 and deactivate the wireless charging unit 320.

[0105] In addition, it has been described above that the processor 120 includes the capacitance calculator 602 and the charging controller 604. This is to facilitate understanding of the present disclosure, and the operation of the capacitance calculator 602 and the operation of the charging controller 604 may be described as being performed by the processor 120.

[0109] According to various embodiments of the present disclosure, the processor may be configured to execute a charging function of activating the wireless charging coil and deactivating the touch panel.

[0110] According to various embodiments of the present disclosure, the processor may be configured to transmit a designated signal for determining the presence of the wireless power receiving unit and identifying the wireless power receiving unit in response to executing the charging function.

[0111] According to various embodiments of the present disclosure, the processor may be configured to stop performing the charging function when it is determined that the wireless power receiving unit does not exist or the wireless power receiving unit is not recognized.

[0112] According to various embodiments of the present disclosure, the processor may be configured to monitor a state of an input subject when executing a charging function, and stop executing the charging function when the state of the input subject satisfies a specified condition.

[0113] According to various embodiments of the present disclosure, the designated condition may include at least one of a case where the input subject exceeds a designated distance from the touch panel or a case where a signal notifying completion of charging is received from the input subject.

[0114] According to various embodiments of the present disclosure, the touch panel may include: a first sensor layer (e.g., the first sensor layer 410), which includes a first electrode pattern and a plurality of first openings formed on the first electrode pattern; and a second sensor layer (e.g., the second sensor layer 420), which is disposed below the first sensor and includes a second electrode pattern and a plurality of second openings formed on the second electrode pattern.

[0115] According to various embodiments of the present disclosure, the touch panel may further include a ground layer (eg, the ground layer 430 ) disposed under the second sensor layer and configured to be aligned with at least one of the first electrode pattern or the second electrode pattern.

[0116] According to various embodiments of the present disclosure, the ground layer may include at least one third opening (eg, opening 434 ), and the wireless charging coil may wirelessly transmit power through the plurality of first openings, the plurality of second openings, and the at least one third opening.

[0117] According to various embodiments of the present disclosure, a position of the at least one third opening may correspond to at least one of positions of the plurality of first openings or positions of the plurality of second openings.

[0118] Figure 7 700 is a flowchart illustrating a method for providing a wireless charging function by an electronic device according to an embodiment of the present disclosure. Hereinafter, in an embodiment of the present disclosure, operations may be performed sequentially, but not necessarily sequentially. For example, the order of operations may be changed, and at least two operations may be performed in parallel.

[0119] Reference Figure 7 According to various embodiments of the present disclosure, in operation 710, the electronic device 101 (eg, Figure 1 According to one embodiment of the present disclosure, the processor 120 may detect a touch input on the touch panel 214 when the wireless charging unit 320 (eg, the wireless charging coil 322) is deactivated.

[0120] According to various embodiments of the present disclosure, in operation 720, the electronic device 101 (eg, Figure 1The processor 120 in the touch panel can determine the touch input subject based on the capacitance change. According to one embodiment of the present disclosure, the processor 120 can calculate the capacitance change (capacitance change rate) by comparing the first capacitance when no touch input is detected with the second capacitance when the touch input is detected, and the calculated capacitance change can be used to determine the input subject that has performed the touch input. For example, as described above, the input subject can be divided into a subject that requires a charging function and a subject that requires a touch function, and the subject will produce different capacitance changes when touching the touch panel. In view of this, the processor 120 can store the capacitance change in the form of a table, and can determine the touch input subject corresponding to the calculated capacitance change.

[0121] According to various embodiments of the present disclosure, in operation 730, the electronic device 101 (eg, Figure 1 The processor 120 in the embodiment may activate the wireless charging function in response to determining that the input subject is a charging subject that needs to be charged. According to one embodiment of the present disclosure, the processor 120 may activate the wireless charging unit 320 to perform the charging function. For example, as described above with reference to Figure 4A and Figure 4B As described, the power generated by the activated wireless charging unit 320 can be transmitted to the touch input body through a path (e.g., at least one opening) formed in the touch panel 214. According to various embodiments of the present disclosure, the processor 120 can prevent unnecessary power consumption by deactivating the touch panel 214 when performing a charging function.

Hereinafter, in the embodiments of the present disclosure, the operations may be performed sequentially, but not necessarily sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0123] Reference Figure 8 According to various embodiments of the present disclosure, in operation 810, the electronic device 101 (eg, Figure 1The processor 120 in the touch panel 214 may determine (configure) a subject recognition area of ​​the touch panel. The subject recognition area is a standard for distinguishing a subject that requires a charging function from a subject that requires a touch function, and may be a standard range in which the face of an input subject that has touched the touch panel (e.g., a subject that requires a charging function) can be identified. According to one embodiment of the present disclosure, the processor 120 may determine a subject recognition area based on at least some detection nodes of the touch panel 214, whose capacitance changes have been detected. For example, the processor 120 may determine a subject detection area that includes a detection node whose maximum capacitance has been detected (whose capacitance change has been detected) with reference to a plurality of detection nodes, eight detection nodes in the X-axis direction, and eight detection nodes in the Y-axis direction. However, this is merely an example, and the processor 120 may determine a subject recognition area having various numbers of detection nodes.

[0124] According to various embodiments of the present disclosure, in operation 820, the electronic device 101 (eg, Figure 1 The processor 120 in the main body identification area can calculate the standard deviation of the determined main body identification area. According to one embodiment of the present disclosure, the processor 120 can use the standard deviation to determine the distribution of the detection nodes (whose capacitance changes have been detected) in the main body identification area. For example, the processor 120 can obtain the standard deviation of the main body identification area by calculating the average value of the deviation (for example, the difference between the capacitance of the detection node and the average capacitance of the main body identification area), and then obtaining the square root of the average value of the deviation, as shown in Formula 1 below.

[0125]

[0126] For example, in Formula 1, σ represents the standard deviation of the body recognition area, ч represents the average capacitance of the body recognition area, and ΔC(a+i,b+j) represents the deviation of nodes a and b included in the body recognition area.

[0127] According to various embodiments of the present disclosure, in operation 830, the electronic device 101 (eg, Figure 1 The processor 120 in the embodiment may determine the touch input subject based on the standard deviation.

Fig. 9 The operation can be Figure 8 Various embodiments of operation 830 in FIG. 8 are described below. In the embodiments of the present disclosure, operations may be performed sequentially, but not necessarily sequentially. For example, the order of operations may be changed, and at least two operations may be performed in parallel.

[0132] Reference Fig. 9 According to various embodiments of the present disclosure, in operation 910, the electronic device 101 (eg, Figure 1 The processor 120 in the embodiment may determine whether the calculated standard deviation is outside the reference deviation range. According to one embodiment of the present disclosure, as described above, the reference deviation range may be a capacitance range that may be changed by a predetermined input subject that requires a touch function. For example, the reference deviation range may have a standard deviation for distinguishing an input subject that requires a touch function from an input subject that requires a wireless charging function, as described in Table 1, for example, may include a range that exceeds the fourth range but does not exceed the third range.

[0133] According to various embodiments of the present disclosure, when a standard deviation exceeding a reference deviation range is calculated, the electronic device 101 (eg, Figure 1 The processor 120 in the embodiment may determine in operation 920 that a subject associated with a touch function has been detected.

[0134] According to various embodiments of the present disclosure, when a standard deviation that does not exceed a reference deviation range is calculated, the electronic device 101 (eg, Figure 1 The processor 120 in the embodiment may determine in operation 930 that a subject related to the wireless charging function has been detected.

[0140] Reference FIG. 10A to FIG. 10D It is found that when an electronic device or wireless headset requiring a wireless charging function touches the touch pad 214, the standard deviation of the touch pad 214 is significantly lower than the standard deviation when a finger or a palm touches the touch pad 214. This may indicate that different ranges of standard deviations are measured according to the characteristics of the input subject touching the touch pad 214.
