DETAILED DESCRIPTION
[0037] The principles and spirits of the present disclosure will be described below with reference to a number of exemplary embodiments. It should be understood that the embodiments are given only so that those skilled in the art can better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way.

[0040] For example, the touch device can be an electromagnetic handwriting panel, which is a simple and fast handwriting device. The electromagnetic handwriting panel can be used with an electromagnetic pen. The electromagnetic handwriting panel can include a transmitting coil and a receiving coil.

The receiving coil will receive the oscillation signals emitted by the electromagnetic pen, thereby realizing coordinate positioning and data transmission of the electromagnetic pen.
[0041] Figure 1 is a structural schematic diagram of a touch panel provided by the related art. Figure 2 is a positioning principle schematic diagram of a touch panel provided by the related art.
[0042] In the related art, as shown in Figure 1 , the touch panel is provided with a plurality of electrodes arranged along a first direction. The electrodes can include first electrodes 21 and third electrodes 23, which are arranged along a second direction in turn. The first direction and the second direction can be two opposite directions. For example, the first direction can be the X direction shown in Figure 1 , and the second direction can be the Y direction shown in Figure 1 .
[0043] The first type of electrodes 21 can be connected to the first type of wires 30, which extend in the first direction to the processing component 50. The third type of electrodes 23 can be connected to the second type of wires 40, which extend in the second direction to the processing component 50. The processing component 50 controls the conduction of two electrodes in the plurality of electrodes, so that the electrodes and the wires connected thereto form a coil. For example, the processing component 50 can control the conduction of the first electrode and the fourth electrode from the left in the first type of electrodes 21 and the first electrode and the fourth electrode from the left in the third type of electrodes 23. Figure 1 The first electrode and the fourth electrode from the left in the first type of electrodes 21 and the first electrode and the fourth electrode from the left in the third type of electrodes 23 are both connected to the first type of wires 30, which extend in the first direction. The coil formed by the two electrodes covers the area between the two electrodes, so that the coil can well receive the electromagnetic induction signal in the area. Figure 1 The first electrode and the fourth electrode from the left in the first type of electrodes 21 and the first electrode and the fourth electrode from the left in the third type of electrodes 23 are both connected to the first type of wires 30, which extend in the first direction. The coil formed by the two electrodes covers the area between the two electrodes, so that the coil can well receive the electromagnetic induction signal in the area.
[0044] In the process of forming different coils, the electrodes adjacent to the third type of electrodes 23 in the first type of electrodes 21 need to form a coil with the third type of electrodes 23. When the processing component 50 controls the conduction of the Nth electrode in the first type of electrodes 21 and the Mth electrode in the third type of electrodes 23 to form a coil, for example, as shown in FIG. 2, the Nth electrode can be the fourth electrode from the left in the first type of electrodes 21. Figure 2 The first electrode and the fourth electrode from the left in the first type of electrodes 21 and the first electrode and the fourth electrode from the left in the third type of electrodes 23 are both connected to the first type of wires 30, which extend in the first direction. The coil formed by the two electrodes covers the area between the two electrodes, so that the coil can well receive the electromagnetic induction signal in the area. Figure 2 The first electrode and the fourth electrode from the left in the first type of electrodes 21 and the first electrode and the fourth electrode from the left in the third type of electrodes 23 are both connected to the first type of wires 30, which extend in the first direction. The coil formed by the two electrodes covers the area between the two electrodes, so that the coil can well receive the electromagnetic induction signal in the area. Figure 2 The first electrode and the fourth electrode from the left in the first type of electrodes 21 and the first electrode and the fourth electrode from the left in the third type of electrodes 23 are both connected to the first type of wires 30, which extend in the first direction. The coil formed by the two electrodes covers the area between the two electrodes, so that the coil can well receive the electromagnetic induction signal in the area.
[0045] Based on the same principle, when the coil is also used to emit signals, the different coil structures will also cause different signal emission capabilities of the coils, reducing the consistency of the signals emitted by the touch panel.
[0046] To solve the above technical problems, embodiments of the present disclosure provide a touch panel, a touch device, a control method, an electronic device, and a storage medium.
[0047] Figure 3 is a structural schematic diagram of a touch panel provided by an embodiment of the present disclosure.
[0048] In some embodiments, as shown in Figure 3 , the touch panel can include a touch area 11, a processing component 50, and a plurality of electrodes, which can be located in the touch area 11.
[0049] The touch area 11 is an area of the touch panel for being able to recognize a touch signal, and the processing component 50 is used to form a coil by conducting different electrodes to receive an electromagnetic induction signal and obtain touch positioning information. However, the present disclosure is not limited thereto, and the coil can also be used to emit an electromagnetic induction signal to the outside world.
[0050] The touch panel further includes first type wires 30 and second type wires 40. The first type wires 30 can be led out from the touch area 11, surround the touch area 11 in a first direction, and be connected to the processing component 50. The second type wires 40 can be led out from the touch area 11, surround the touch area 11 in a second direction, and be connected to the processing component 50.
[0051] The second direction can be the opposite direction of the first direction. For example, the first direction can be the x direction as shown in Figure 3 , and the second direction can be the y direction as shown in Figure 3 .
[0052] The electrodes can include first type electrodes 21, second type electrodes 22, and third type electrodes 23, which are arranged in the touch area 11 in the second direction in order, i.e., the second type electrodes 22 are located between the first type electrodes 21 and the third type electrodes 23. The area occupied by the first type electrodes 21 and the second type electrodes 22 in the touch area 11 is equal to the area occupied by the third type electrodes 23 in the touch area 11, or the area occupied by the second type electrodes 22 and the third type electrodes 23 in the touch area 11 is equal to the area occupied by the first type electrodes 21 in the touch area 11, but the present disclosure is not limited thereto, and the area occupied by the first type electrodes 21 in the touch area 11 can also be equal to the area occupied by the third type electrodes 23 in the touch area 11.
[0053] The first type electrodes 21 are connected to the first type wires 30, the second type electrodes 22 are connected to the first type wires 30 and the second type wires 40, and the third type electrodes 23 are connected to the second type wires 40, wherein the first type wires 30 and the second type wires 40 can be connected to the same end of the second type electrodes 22. The processing component 50 conducts two different wires to conduct the electrodes connected to the wires and form a coil. The processing component 50 can conduct different combinations of wires to form different coils at different positions of the touch area 11, and thus the touch positioning information can be obtained according to the positions of the coils and the electromagnetic induction signal.
[0054] When the processing component 50 passes through the conductive wires and electrodes to form a loop, the processing component 50 can pass through two of the first type of conductive wires 30 to pass through two electrodes connected to the first type of conductive wires 30 and form a loop. Since the two first type of conductive wires 30 extend in the same direction and are connected to the processing component 50, the closed loop formed by the electrodes and the conductive wires can cover the area between the two electrodes and can well receive the signals emitted by the electromagnetic induction signal source adjacent to the area.
[0055] The processing component 50 can also pass through two of the second type of conductive wires 40 to pass through two electrodes connected to the second type of conductive wires 40 and form a loop. Since the two second type of conductive wires 40 extend in the same direction and are connected to the processing component 50, the closed loop formed can cover the area between the two electrodes and can well receive the signals emitted by the electromagnetic induction signal source adjacent to the area.
[0056] When the touch panel needs to form multiple loops at the same time, the processing component 50 can pass through two of the first type of conductive wires 30 and pass through two of the second type of conductive wires 40, that is, the processing component 50 can pass through two conductive wires extending in the same direction and form a closed loop by combining the electrodes connected to the conductive wires. The closed loop can cover the area between the two electrodes.
[0057] The present disclosure provides a second type of electrode 22 between the first type of electrode 21 connected only to the first type of conductive wire 30 and the third type of electrode 23 connected only to the second type of conductive wire 40, and the second type of electrode 22 is connected to both the first type of conductive wire 30 and the second type of conductive wire 40. The second type of electrode 22 can be combined with the first type of electrode 21 to form a closed loop by passing through the first type of conductive wire 30, and can be combined with the third type of electrode 23 to form a closed loop by passing through the second type of conductive wire 40. This avoids the need for the first type of electrode 21 adjacent to the third type of electrode 23 to pass through the third type of electrode 23, and the closed loop structure formed is different from the loop structure formed in other areas, so that the first type of electrode 21 and the second type of electrode 22 can pass through two first type of conductive wires 30, or the second type of electrode 22 and the third type of electrode 23 can pass through two second type of conductive wires 40 to form a closed loop, so that the loop structures formed by the multiple electrodes and conductive wires of all touch areas of the touch area 11 are consistent.
[0058] The present disclosure effectively solves the problem that the coil structure formed in the specific area such as the middle area of the touch area is inconsistent with the coil structure formed in other areas, enhances the electromagnetic induction signal receiving capability of the coil formed in the touch area 11, improves the consistency of the electromagnetic induction signal receiving capability of different coils, improves the linearity of the touch panel in receiving the electromagnetic induction signal, and improves the accuracy of touch positioning. Moreover, when the coil is also used to emit electromagnetic induction signals to the outside world, the electromagnetic induction signal emitting capability of different coils can be improved, and the consistency of the signals emitted by the touch panel is improved.
[0059] In some embodiments, as shown in FIG. 1, the processing component 50 can be configured to turn on two electrodes of the plurality of electrodes with an interval of P electrodes and form a coil, P being greater than or equal to 0, wherein the number of the second type of electrodes 22 is greater than or equal to P+1. Figure 3
[0060] When the processing component 50 forms different coils, the two electrodes forming the coil are spaced apart by P electrodes.
[0061] When the number of the second type of electrodes 22 is configured to be greater than or equal to P+1, the first type of electrode 21 closest to the second type of electrode 22 can form a coil with the second type of electrode 22 spaced apart by P electrodes, i.e., the P+1th second type of electrode 22, and the third type of electrode 23 closest to the first type of electrode 21 is spaced apart from the first type of electrode 21 by P+1 electrodes, so that the first type of electrode 21 and the third type of electrode 23 cannot be turned on and form a coil that needs to surround the touch area 11, thereby avoiding the situation that the first type of electrode 21 and the third type of electrode 23 are turned on to form a coil that needs to surround the touch area 11, and the coil structure is inconsistent with the coil structure in other areas, so that the coil structures formed by the plurality of electrodes and the wires are consistent, the electromagnetic induction signal receiving capability of the coil formed in the touch area 11 is enhanced, the consistency of the electromagnetic induction signal receiving capability of different coils is improved, the linearity of the touch panel in receiving the electromagnetic induction signal is improved, and the accuracy of touch positioning is improved.
[0062] In some embodiments, P can be any integer from 1 to 3, and exemplary, P can be 2. When the value of P is greater than the above range, the coil area formed by the electrode and the wire will be too large, resulting in a decrease in the energy intensity that the coil can receive, and also making the coil too large in relation to the corresponding area of the touch area 11, which reduces the positioning accuracy of the coil for the electromagnetic induction signal, making it difficult to obtain an accurate touch position through the coil. When the value of P is less than the above range, in the case of a fast-moving electromagnetic induction signal source, the electromagnetic induction signal source can be out of the range of a single coil area, resulting in a loss of touch positioning information. However, the present disclosure is not limited thereto, and the specific value of P can be changed according to the interval distance between the electrodes and the specific use scenario.
[0063] Figure 4 is a schematic diagram of a positioning principle of a touch panel provided by an embodiment of the present disclosure.
[0064] In some embodiments, as shown in Figure 3 and Figure 4 , the two electrodes that make up the coil can be spaced apart by 2 electrodes, P+1 can be 3, and the number of second-type electrodes 22 is 3. When the processing assembly 50 turns on the Nth electrode of the first-type electrodes 21 closest to the third-type electrodes 23, the Nth electrode can be turned on with the Mth electrode spaced apart by P electrodes to form a closed coil, and the Mth electrode is the P+1th second-type electrode 22. Therefore, the electrode of the first-type electrodes 21 closest to the third-type electrodes 23 can be turned on with the second-type electrodes 22 to form a coil, and an effective closed coil can be formed by the first-type wire 30 of the Nth electrode and the first-type wire 30 of the Mth electrode, covering the area between the Nth electrode and the Mth electrode.
[0065] In some embodiments, the processing assembly 50 can turn on the first-type wire 30 connected to the first-type electrodes 21, and the first-type wire 30 connected to another electrode to control the first-type electrodes 21 and the other electrode to be turned on and form a coil, wherein the other electrode is the first-type electrodes 21 and the second-type electrodes 22. Wherein the other electrode is the first-type electrodes 21 and the second-type electrodes 22 means that the first-type electrodes 21 can be turned on with the first-type electrodes 21 through the first-type wire 30 to form a coil, and the first-type electrodes 21 can also be turned on with the second-type electrodes 22 through the first-type wire 30 to form a coil.
[0066] And the processing component 50 can also conduct the second type of wire 40 connected with the third type of electrode 23, and the second type of wire 40 connected with another electrode, to control the third type of electrode 23 and the other electrode to be conducted and form a coil, wherein the other electrode is the second type of electrode 22 and the third type of electrode 23. Wherein the other electrode is the second type of electrode 22 and the third type of electrode 23 means that the third type of electrode 23 can be conducted with the second type of electrode 22 through the second type of wire 40 and form a coil, and the third type of electrode 23 can also be conducted with the third type of electrode 23 through the second type of wire 40 and form a coil.
[0067] By enabling the first type of electrode 21 to be conducted with the first type of electrode 21 having the first type of wire 30, and also to be conducted with the second type of electrode 22 having the first type of wire 30, and enabling the third type of electrode 23 to be conducted with the second type of electrode 22 having the second type of wire 40, and also to be conducted with the third type of electrode 23 having the second type of wire 40, the consistency of the coil structure formed by the electrodes and wires being conducted can be achieved, the electromagnetic induction signal receiving capability of the coil formed in the touch area 11 is enhanced, the consistency of the electromagnetic induction signal receiving capability of different coils is improved, the linearity of the touch panel receiving electromagnetic induction signals is improved, and the accuracy of touch positioning is improved.
[0068] In some embodiments, the processing component 50 can conduct the first type of wire 30 connected with the first type of electrode 21, and the first type of wire 30 connected with another electrode, to control the first type of electrode 21 and the other electrode to be conducted and form a coil, wherein the other electrode is the first type of electrode 21 and the second type of electrode 22. The processing component 50 can also conduct the second type of wire 40 connected with the third type of electrode 23, and the second type of wire 40 connected with another electrode, to control the third type of electrode 23 and the other electrode to be conducted and form a coil, wherein the other electrode is the second type of electrode 22 and the third type of electrode 23.
[0069] And the processing component 50 can also conduct the second type of wire 40 connected with the third type of electrode 23, and the second type of wire 40 connected with another electrode, to control the third type of electrode 23 and the other electrode to be conducted and form a coil, wherein the other electrode is the second type of electrode 22 and the third type of electrode 23. Wherein the other electrode is the second type of electrode 22 and the third type of electrode 23 means that the third type of electrode 23 can be conducted with the second type of electrode 22 through the second type of wire 40 and form a coil, and the third type of electrode 23 can also be conducted with the third type of electrode 23 through the second type of wire 40 and form a coil.
[0070] The embodiment makes the electrode and the wire conductive to form a consistent coil structure, so as to improve the consistency of the electromagnetic induction signal receiving capability of different coils, and make the second electrode 22 conductive with another second electrode 22 spaced by P electrodes to form a coil, thereby improving the coverage density of the coil on the touch panel and improving the accuracy of touch positioning.
[0071] In some embodiments, when the processing component 50 controls the second electrode 22 spaced by P electrodes to conduct and form a coil, the number of the second electrode 22 is at least 2 more than the number of P, for example, the number of the second electrode 22 is 3, and P is 1, so that the two second electrodes 22 spaced by one electrode are conductive to form a coil.
[0072] In some embodiments, the number of the second electrode 22 can be equal to P+1, and in the case that the number of the second electrode 22 is P+1, the electrode spaced by P electrodes from the second electrode 22 is the first electrode 21 or the third electrode 23, at this time, the second electrode 22 is only conductive with the first electrode 21 or the third electrode 23 to form a coil, at this time, the second electrode 22 can meet the requirement of the first electrode 21 and the third electrode 23 conductive with the second electrode 22 to form a structure same coil with the lowest number of electrodes, thereby reducing the total number of the second electrode 22, and reducing the setting cost of the touch panel. For example, when P is 2 and the number of the second electrode 22 is 3, the second electrode 22 will not be conductive, at this time, the first electrode 21 will be conductive between the first electrodes 21 spaced by two electrodes, the third electrode 23 will be conductive between the third electrodes 23 spaced by two electrodes, the second electrode 22 will be conductive with the first electrode 21 spaced by two electrodes, and / or the second electrode 22 will be conductive with the third electrode 23 spaced by two electrodes, and the coil structure formed after all the electrodes are conductive is consistent.
[0073] Figure 5 is a structural schematic diagram of a touch panel provided by an embodiment of the present disclosure.
[0074] In some embodiments, as shown in Figure 5 The second electrode 22 can include a first sub-electrode 221 and a second sub-electrode 222, wherein the first sub-electrode 221 can be adjacent to the first electrode 21, and the second sub-electrode 222 can be adjacent to the third electrode 23. When the number of the second electrode 22 is greater than P+1, the first sub-electrode 221 and the second sub-electrode 222 can be spaced by P electrodes.
[0075] The processing component 50 can make the first type of wire 30 connected with the first sub-electrode 221 and the first type of wire 30 connected with the second sub-electrode 222 conductive to make the first sub-electrode 221 and the second sub-electrode 222 conductive to form a coil.
[0076] The processing component 50 can also turn on the second type of conductive wire 40 connected to the first sub-electrode 221 and the second type of conductive wire 40 connected to the second sub-electrode 222 to turn on the first sub-electrode 221 and the second sub-electrode 222 and form a coil.
[0077] Through the above-mentioned turn-on configuration, the processing component 50 can turn on the first sub-electrode 221 and the second sub-electrode 222 and form a closed coil, avoid the first sub-electrode 221 and the second sub-electrode 222 to turn on the conductive wire in the opposite direction of extension, make the structure of each coil formed by the plurality of electrodes and conductive wires consistent, enhance the electromagnetic induction signal receiving ability of the coil formed in the touch area 11, improve the consistency of the electromagnetic induction signal receiving ability of different coils, improve the linearity of the touch panel receiving electromagnetic induction signal, and improve the accuracy of touch positioning.
[0078] In some embodiments, as shown in FIG. 1, the extension directions of the plurality of electrodes are parallel to each other. Figure 3
[0079] Each of the first type of conductive wire 30 can include a first extension section 31, the first extension section 31 can be connected to the first type of electrode 21, the first extension section 31 can also be connected to the second type of electrode 22, the first extension section 31 extends out of the touch area 11 from the first type of electrode 21 or the second type of electrode 22. The extension direction of the first extension section 31 is parallel to the extension direction of the plurality of electrodes, and the length of the plurality of first extension sections 31 gradually increases along the second direction, so that each first type of conductive wire 30 has different distances from the edge of the touch area 11 when extending along the first direction, and the distance between the first type of conductive wire 30 and the edge of the touch area 11 gradually increases along the second direction, so that the first type of conductive wire 30 close to the third type of electrode 23 is routed on the periphery, avoiding the first type of conductive wire 30 close to the third type of electrode 23 to cross the first type of conductive wire 30 away from the third type of electrode 23, reducing the cross situation of the wiring path between the plurality of first type of conductive wires 30.
[0080] Each second-type conductive line 40 may include a second extension segment 41. The second extension segment 41 may be connected to the second-type electrode 22, and the first extension segment 31 may be connected to the third-type electrode 23. The second extension segment 41 extends from the second-type electrode 22 or the third-type electrode 23 and extends out of the touch area 11. The extension direction of the second extension segment 41 is parallel to the extension direction of the multiple electrodes. The lengths of the multiple second extension segments 41 gradually increase along the first direction, so that each second-type conductive line 40 has a different distance from the edge of the touch area 11 when extending in the second direction. The distance between the second-type conductive line 40 and the edge of the touch area 11 gradually increases along the first direction, so that the second-type conductive lines 40 closer to the first-type electrodes 21 are routed on the periphery, preventing the second-type conductive lines 40 closer to the first-type electrodes 21 from crossing with the second-type conductive lines 40 farther away from the first-type electrodes 21, thereby reducing the possibility of the routing paths of the multiple second-type conductive lines 40 intersecting.
[0081] The above configuration can reduce the crossing of routing paths between the first type of wires 30 and the crossing of routing paths between the second type of wires 40, thereby reducing the additional cost caused by the crossing of wire routing and reducing crosstalk between wires to ensure the touch performance of the touch panel.
[0082] In some embodiments, as Figure 3 As shown, the touch panel may include a bus 32 , which may be connected to the second type of electrodes 22 , at least a portion of the bus 32 may constitute a first extension segment 31 , and at least a portion of the bus 32 may further constitute a second extension segment 41 .
[0083] That is, the first type of wire 30 and the second type of wire 40 connected to the second type of electrode 22 merge to form a bus 32, and are connected to the second type of electrode 22 through the bus 32, thereby reducing the number of wires directly connected to a single second type of electrode 22, reducing the difficulty of setting up the connection between multiple wires and the second type of electrode 22, reducing the wiring space occupied by the two wires connected to the second type of electrode 22, and simplifying the routing planning of the first type of wire 30 and the second type of wire 40 connected to the second type of electrode 22.
[0084] However, the present disclosure is not limited thereto, and the first extension segment 31 and the second extension segment 41 may also be respectively connected to the same end of the same second-type electrode 22 .
[0085] Figure 6 Schematic diagram of the structure of a touch panel with a substrate provided by an embodiment of the present disclosure.
[0086] In some embodiments, as Figure 6 As shown, the touch panel may include a substrate 10 , and a touch area 11 , a first type of conductive line 30 , and a second type of conductive line 40 may be disposed on the substrate 10 .
[0087] The substrate 10 can be a skeleton structure of the touch panel, and can provide wiring space for the first type of conductive lines 30 and the second type of conductive lines 40, and provide installation and fixation for the electrodes.
[0088] Since the second type of electrodes 22 are connected to the first type of conductive lines 30 and the second type of conductive lines 40, and the number of the second type of electrodes 22 is multiple, the wiring paths of the first type of conductive lines 30 and the wiring paths of the second type of conductive lines 40 have wiring crossing positions.
[0089] The touch panel can include an insulating layer at the wiring crossing positions, and the insulating layer can be arranged between the first type of conductive lines 30 and the second type of conductive lines 40. For example, the first type of conductive lines 30 can include a metal connecting bridge, and the first type of conductive lines 30 can cross the second type of conductive lines 40 through the metal connecting bridge. The metal connecting bridge can be provided with the insulating layer between the crossing positions and the second type of conductive lines 40. In this way, without increasing the area of the substrate 10, the first type of conductive lines 30 and the second type of conductive lines 40 can be prevented from short-circuiting at the wiring crossing positions, and the first type of conductive lines 30 and the second type of conductive lines 40 can cross each other to ensure the performance of signal transmission.
[0090] In other embodiments, the substrate 10 can also be provided with through holes penetrating the substrate 10. The through holes can be used to extend the first type of conductive lines 30 and the second type of conductive lines 40 to different surfaces of the substrate 10 for wiring. In this way, without increasing the area of the substrate 10, the first type of conductive lines 30 and the second type of conductive lines 40 can be prevented from short-circuiting at the wiring crossing positions, and the first type of conductive lines 30 and the second type of conductive lines 40 can cross each other to ensure the performance of signal transmission.
[0091] In some embodiments, both the insulating layer arranged between the first type of conductive lines 30 and the second type of conductive lines 40 and the through holes penetrating the substrate 10 can be provided. In this way, without increasing the area of the substrate 10, the first type of conductive lines 30 and the second type of conductive lines 40 can be prevented from short-circuiting at the wiring crossing positions, and the first type of conductive lines 30 and the second type of conductive lines 40 can cross each other to ensure the performance of signal transmission.
[0092] In some embodiments, as shown in FIG. 2, the first type of conductive lines 30 and the second type of conductive lines 40 can be arranged in a staggered manner. Figure 3As shown, the plurality of electrodes further comprises fourth electrodes 24, the extending direction of the fourth electrodes 24 can be perpendicular to the extending direction of the first electrodes 21, and the plurality of fourth electrodes 24 can be arranged along a direction perpendicular to the first direction. The first electrodes 21, the second electrodes 22 and the third electrodes 23 are used to detect touch information in the first direction, and the fourth electrodes 24 are used to detect touch information in a direction perpendicular to the first direction based on the same or similar principle as the first electrodes 21, the second electrodes 22 and the third electrodes 23. By obtaining touch information containing position coordinates in two perpendicular directions, the position of the touch accessory can be located.
[0093] Based on the same concept, the embodiment of the present disclosure further provides a touch device, which can comprise a touch panel. The touch device can receive electromagnetic induction signals emitted by a touch accessory through different coils formed by electrodes on the panel, and then obtain positioning information of the touch accessory through the electromagnetic induction signals obtained by the different coils.
[0094] Figure 7 FIG. 4 is a flowchart of a control method of a touch panel according to an embodiment of the present disclosure.
[0095] Based on the same concept, the embodiment of the present disclosure further provides a control method of a touch panel, which can comprise the following steps as shown in Figure 7 S10: According to the pre-stored coil and wire correspondence relationship, turn on the first type of wire connected to the Nth electrode and the first type of wire connected to the Mth electrode, and turn on the second type of wire connected to the Nth electrode and the second type of wire connected to the Mth electrode, to control the Nth electrode and the Mth electrode to be turned on and form a coil, and obtain the electromagnetic induction signal received by the coil; S20: Control N to increase from 1, and sequentially form a plurality of coils to respectively obtain electromagnetic induction signals of the plurality of coils; S30: Obtain touch positioning information according to the electromagnetic induction signals received by each coil.
[0096] Wherein, M and N are positive integers, and M-N is greater than or equal to 1; The first type of wire extends along the first direction, the second type of wire extends along the second direction, and the Nth electrode and the Mth electrode are arranged along the second direction in sequence.
[0097] When the touch panel needs to turn on a specific coil, the corresponding two wires can be turned on according to the pre-stored coil and wire correspondence relationship, so as to turn on the specific coil.
[0098] Subsequently, the first type of wire between the Nth electrode and the Mth electrode can be connected to form a closed coil, or the second type of wire between the Nth electrode and the Mth electrode can be connected to form a closed coil. By connecting wires extending in the same direction, the opening between the two wires can be closed, thus forming a closed coil. Furthermore, by increasing N from 1, the electrodes in the touch area sequentially form coils, and the coils cover different positions in the touch area, thereby achieving scanning of the touch area. For example, N can be 1, 2, 3, 4, 5, and 6, and M can be 4, 5, 6, 7, 8, and 9.
[0099] Touch positioning information can be obtained by processing the electromagnetic induction signals received by multiple coils at different positions.
[0100] The present disclosure can close the opening structure between the two wires by conducting the wires extending in the same direction, thereby forming a closed coil, thereby improving the electromagnetic induction signal receiving capability of the coil, and avoiding conducting the first type of wire and the second type of wire extending in opposite directions, thereby avoiding the situation where the electrodes and the wires are conducted to form a coil that needs to surround the touch area, and causing the coil structure to be inconsistent with the coil structure in other areas, so that the coil structures formed by multiple electrodes and wires are consistent, thereby enhancing the electromagnetic induction signal receiving capability of the coil formed in the touch area, improving the consistency of the electromagnetic induction signal receiving capability of different coils, improving the linearity of the touch panel receiving the electromagnetic induction signal, and improving the accuracy of touch positioning.
[0101] Figure 8 This is a flow chart of a touch panel control method provided by an embodiment of the present disclosure.
[0102] In some embodiments, as Figure 8 As shown, the control method may include the following steps: S11: Based on the Nth electrode being the first type electrode, conducting the first type wire connected to the Nth electrode and the first type wire connected to the Mth electrode to control the Nth electrode and the Mth electrode to conduct to form a coil, and obtaining an electromagnetic induction signal received by the coil, wherein the Mth electrode is the first type electrode or the second type electrode; S12: Based on the M-th electrode being the third-type electrode, conducting the second-type wire connected to the N-th electrode and the second-type wire connected to the M-th electrode to control the M-th electrode and the N-th electrode to form a coil, and acquiring an electromagnetic induction signal received by the coil, wherein the N-th electrode is the second-type electrode or the third-type electrode; S20: controlling N to increase from 1, forming a plurality of coils in sequence, and obtaining electromagnetic induction signals of the plurality of coils respectively; S30: Acquire touch positioning information according to the electromagnetic induction signals received by each coil.
[0103] The touch panel comprises a plurality of electrodes, the plurality of electrodes comprising first-type electrodes, second-type electrodes and third-type electrodes arranged in sequence along a second direction, the first-type electrodes being connected with first-type wires, the second-type electrodes being connected with the first-type wires and second-type wires, and the third-type electrodes being connected with the second-type wires.
[0104] According to the pre-stored correspondence between the coils and the wires, the first-type electrodes can be connected with the first-type electrodes or the second-type electrodes, and the third-type electrodes can be connected with the second-type electrodes or the third-type electrodes. According to the above configuration, the first-type wires and the second-type wires extending in opposite directions can be avoided, and thus the coils formed by the electrodes can all form closed coils with consistent structures, so that the consistency of the electromagnetic induction signal receiving capability of different coils can be improved, and the linearity of the touch panel in receiving electromagnetic induction signals can be improved.
[0105] The present disclosure sets the second-type electrodes between the first-type electrodes connected with only the first-type wires and the third-type electrodes connected with only the second-type wires, and connects the second-type electrodes with both the first-type wires and the second-type wires, so that the second-type electrodes can be combined to form closed coils with the first-type electrodes by connecting the first-type wires, and can be combined to form closed coils with the third-type electrodes by connecting the second-type wires. In this way, the first-type electrodes adjacent to the third-type electrodes can be avoided from forming coils that need to surround the touch area and causing inconsistent coil structures with other areas after being connected with the third-type electrodes, so that closed coils can be formed by connecting two first-type wires, and closed coils can be formed by connecting two second-type wires, the structures of the coils formed by the plurality of electrodes and the wires are consistent, the electromagnetic induction signal receiving capability of the coils formed in the touch area is enhanced, the consistency of the electromagnetic induction signal receiving capability of different coils is improved, the linearity of the touch panel in receiving electromagnetic induction signals is improved, and the accuracy of touch positioning is improved.
[0106] Figure 9 is a flowchart of a control method of a touch panel provided by an embodiment of the present disclosure.
[0107] In some embodiments, as shown in Figure 9 the control method can comprise the following steps: S11: according to the Nth electrode being a first-type electrode, connecting a first-type wire connected with the Nth electrode and a first-type wire connected with the Mth electrode to control the Nth electrode and the Mth electrode to be connected and form a coil, and acquiring an electromagnetic induction signal received by the coil, wherein the Mth electrode is a first-type electrode or a second-type electrode. S12: according to the Mth electrode being the third type electrode, turning on the second type wire connected with the Nth electrode and the second type wire connected with the Mth electrode to control the Mth electrode and the Nth electrode to be turned on and form a coil, and obtaining the electromagnetic induction signal received by the coil, wherein the Nth electrode is the second type electrode or the third type electrode; S13: according to the Nth electrode and the Mth electrode being the second type electrode, turning on the wire in the same extension direction connected with the Nth electrode and the Mth electrode; S20: controlling N to increase from 1, and sequentially forming a plurality of coils to obtain electromagnetic induction signals of the plurality of coils respectively; S30: obtaining touch positioning information according to the electromagnetic induction signals received by the coils.
[0108] According to the pre-stored correspondence between the coil and the wire, the first type electrode can be turned on with the first type electrode or the second type electrode, or the third type electrode can be turned on with the second type electrode or the third type electrode. According to the above configuration, the first type wire and the second type wire extending in opposite directions can be avoided, and the situation that the electrodes and the wires are turned on to form a coil that needs to surround the touch area and causes the coil structure to be inconsistent with the coil structure of other areas can be avoided.
[0109] And when the Nth electrode and the Mth electrode are the second type electrode, the Nth electrode and the Mth electrode can be turned on to the wire in the same extension direction, the first sub-electrode and the second sub-electrode can be turned on to the wire in the opposite extension direction, and the situation that the electrodes and the wires are turned on to form a coil that needs to surround the touch area and causes the coil structure to be inconsistent with the coil structure of other areas can be avoided, so that the coil structures formed by the plurality of electrodes and wires are consistent, the electromagnetic induction signal receiving capability of the coil formed in the touch area is enhanced, the consistency of the electromagnetic induction signal receiving capability of different coils is improved, the linearity of the touch panel receiving the electromagnetic induction signal is improved, and the accuracy of touch positioning is improved.
[0110] The second type of electrode can be combined with the first type of electrode to form a closed loop by conducting the first type of wire, and can be combined with the third type of electrode to form a closed loop by conducting the second type of wire. This avoids the situation where the first type of electrode adjacent to the third type of electrode is conducted with the third type of electrode to form a loop that needs to surround the touch area, and causes the loop structure to be inconsistent with the loop structure of other areas. Thus, a closed loop can be formed by conducting two first type of wires, and a closed loop can be formed by conducting two second type of wires. This makes the loop structures formed by the multiple electrodes and wires consistent, enhances the electromagnetic induction signal receiving capability of the loop formed in the touch area, improves the consistency of the electromagnetic induction signal receiving capability of different loops, improves the linearity of the touch panel in receiving electromagnetic induction signals, and improves the accuracy of touch positioning.
[0111] Figure 10 is a flowchart of a control method of a touch panel provided by an embodiment of the present disclosure.
[0112] In some embodiments, as shown in Figure 10 the control method can include the following steps: S10: according to a pre-stored loop and wire correspondence relationship, conduct the first type of wire connected to the Nth electrode, and the first type of wire connected to the Mth electrode, and conduct the second type of wire connected to the Nth electrode, and the second type of wire connected to the Mth electrode, to control the Nth electrode and the Mth electrode to be conducted and form a loop, and obtain the electromagnetic induction signal received by the loop; S20: control N to increase from 1, and sequentially form multiple loops to respectively obtain electromagnetic induction signals of the multiple loops; S31: obtain a correspondence curve of electromagnetic induction signal strength and touch area coordinates according to the electromagnetic induction signals received by the loops; S32: determine the touch area coordinates corresponding to the highest point of the correspondence curve; S33: obtain touch positioning information according to the touch area coordinates corresponding to the highest point of the correspondence curve.
[0113] When a specific loop of the touch panel needs to be conducted, the two corresponding wires can be conducted according to the pre-stored loop and wire correspondence relationship, thereby conducting the specific loop.
[0114] Then the first type of wire of the Nth electrode and the Mth electrode can be turned on to form a closed coil, and the second type of wire of the Nth electrode and the Mth electrode can also be turned on to form a closed coil. By turning on the wires extending in the same direction, the open structure between the two wires can be closed to form a closed coil. And by increasing N from 1, the electrodes of the touch area form coils in turn, and the coils cover different positions of the touch area, thereby realizing scanning of the touch area.
[0115] According to the electromagnetic induction signal strength received by the multiple coils at different positions, a curve of the electromagnetic induction signal strength and the touch area coordinates can be obtained, wherein the highest point of the curve represents that the electromagnetic induction signal strength received by the corresponding coil is the highest, and the distance from the touch accessory as the emission source is the closest. Therefore, it can be considered that the touch accessory is located at the position of the coil corresponding to the highest point of the curve, thereby obtaining touch positioning information.
[0116] The present disclosure can close the open structure between the two wires by turning on the wires extending in the same direction, thereby forming a closed coil, thereby improving the electromagnetic induction signal receiving capability of the coil. And avoiding turning on the first type of wire and the second type of wire extending in opposite directions, thereby avoiding the situation that the electrodes and wires form a coil that needs to surround the touch area after being turned on, and causing the coil structure to be inconsistent with the coil structure of other areas. The multiple electrodes and wires form consistent coil structures, thereby enhancing the electromagnetic induction signal receiving capability of the coils formed in the touch area, making the electromagnetic induction signal receiving capability of the multiple coils similar, improving the consistency of the electromagnetic induction signal receiving capability of different coils, improving the linearity of the touch panel receiving electromagnetic induction signals, thereby making the electromagnetic induction signal strength received by the coil and the distance between the coil and the touch accessory closer to the inverse proportional relationship, and improving the accuracy of touch positioning.
