Description

Technical Field

[0001] This disclosure relates to the field of touch technology, specifically to touch panels, touch devices, control methods, electronic devices, and storage media. Background Technology

[0002] With the rapid development of technology, various new touch technologies are being increasingly widely applied in display devices. In touch operation, users can use a stylus to perform touch operations on the device. To achieve stylus positioning, touch panels often have a receiving array composed of multiple electrodes. By connecting different electrodes, coils can be formed at different locations within the touch area. These coils can receive electromagnetic induction signals from the stylus. The varying strengths of the electromagnetic induction signals received by coils at different locations allow for stylus positioning. However, due to limitations in the wiring layout of touch devices, the wiring of some electrodes differs from that of others, resulting in different coil structures. These differences in coil structure lead to significant variations in the electromagnetic induction signal reception capabilities of different coils, interfering with stylus positioning calculations.

This allows the second type of electrode to form a closed coil by combining with the first type of electrode through the first type of wire, and also to form a closed coil by combining with the third type of electrode through the second type of wire. This avoids the situation where the first type of electrode adjacent to the third type of electrode forms a coil that needs to surround the touch area after being connected to the third type of electrode, resulting in an inconsistency between the coil structure and the coil structure in other areas.

[0045] The principles and spirit of this disclosure will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and implement this disclosure, and are not intended to limit the scope of this disclosure in any way.

[0046] It should be noted that although the terms "first," "second," etc., are used herein to describe different modules, steps, and data in the embodiments of this disclosure, these terms are only for distinguishing between different modules, steps, and data, and do not indicate a specific order or degree of importance. In fact, the terms "first," "second," etc., can be used interchangeably.

[0047] The touch panel, touch device, control method, electronic device, and storage medium provided in the embodiments of this disclosure can be applied to touch devices, wherein the touch device can be any of the following: capacitive touch panel, electromagnetic touch panel, touch display screen, capacitive handwriting tablet, and electromagnetic handwriting tablet.

[0048] For example, a touch device could be an electromagnetic writing tablet, a simple and quick interactive handwriting device. An electromagnetic writing tablet can be used in conjunction with an electromagnetic pen. The tablet may include a transmitting coil and a receiving coil. The transmitting coil sends electromagnetic waves to the pen, and the resonant circuit in the pen receives these waves, oscillates, and the oscillation continuously decays. The receiving coil receives the oscillation signal emitted by the pen, thus enabling coordinate positioning and data transmission.

[0049] Figure 1 This is a structural diagram of a touch panel provided by related technologies. Figure 2 This is a schematic diagram of the positioning principle of a touch panel provided by related technologies.

[0050] In related technologies, such as Figure 1As shown, the touch panel has multiple electrodes arranged along a first direction. These electrodes may include a first type of electrode 21 and a third type of electrode 23, which are arranged sequentially along a second direction. The first and second directions can be opposite directions. For example, the first direction can be... Figure 1 The X direction is shown in the diagram, and the second direction can be... Figure 1 The Y direction is shown in the diagram.

[0051] A first type of electrode 21 can be connected to a first type of wire 30, which extends in a first direction to connect to the processing component 50. A third type of electrode 23 can be connected to a second type of wire 40, which extends in a second direction to connect to the processing component 50. The processing component 50 forms a coil by energizing two of the plurality of electrodes, such that the electrodes and the wires connected thereto form a coil. For example, the processing component 50 can be energized... Figure 1 The first electrode from the middle left and Figure 1 The fourth electrode from the left in the middle, both electrodes extend in the first direction through the first type of wire 30, and the coil formed by the two electrodes covers the area between the two electrodes, so that the coil can receive the electromagnetic induction signal located in this area well.

[0052] In the process of forming different coils, a portion of the first type of electrode 21 adjacent to the third type of electrode 23 needs to form a coil with the third type of electrode 23. When the processing component 50 controls the Nth electrode in the first type of electrode 21 and the Mth electrode in the third type of electrode 23 to be turned on and form a coil, for example, as shown... Figure 2 As shown, the Nth electrode can be Figure 2 The fourth electrode from the left in the middle, the Mth electrode can be Figure 2 The seventh electrode from the left has a different coil structure due to the opposing extensions of the first type of conductor 30 and the second type of conductor 40. The first type of conductor 30 needs to extend around one side of the touch area and connect to the processing component 50, while the second type of conductor 40 needs to extend around the other side of the touch area and connect to the processing component 50. The first type of conductor 30 and the second type of conductor 40 are then connected through the processing component 50. This makes the coil formed by the first type of conductor 30, the second type of conductor 40, and the corresponding connected electrodes different from coil structures formed solely by conducting the first type of conductor 30 or solely by conducting the second type of conductor 40. This makes it difficult for this coil to effectively receive signals from the electromagnetic induction signal source in the area between two adjacent electrodes. Consequently, the coil's reception accuracy differs from other coils, reducing the linearity of the receiving array formed by multiple electrodes in receiving electromagnetic induction signals. This reduces the touch area's ability to receive electromagnetic induction signals and interferes with the stylus's positioning calculations. Furthermore, in the case of a narrow bezel touch panel, the limited wiring space restricts coil wiring.

[0053] Based on the same principle, when coils are also used to transmit signals, different coil structures will also lead to different signal transmission capabilities of different coils, reducing the consistency of signals emitted by the touch panel.

[0054] To address the aforementioned technical problems, embodiments of this disclosure provide a touch panel, a touch device, a control method, an electronic device, and a storage medium.

[0055] Figure 3 This is a schematic diagram of the structure of a touch panel provided in an embodiment of this disclosure.

[0056] In some embodiments, such as Figure 3 As shown, the touch panel may include: a touch area 11, a processing component 50, and multiple electrodes, which may be located within the touch area 11.

[0057] Touch area 11 is the area of ​​the touch panel used to recognize touch signals. Processing component 50 is used to form a coil by conducting different electrodes to receive electromagnetic induction signals and obtain touch positioning information. However, this disclosure is not limited to this; the coil can also be used to emit electromagnetic induction signals to the outside world.

[0058] The touch panel also includes a first type of conductor 30 and a second type of conductor 40. The first type of conductor 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 of conductor 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.

[0059] The second direction can be the opposite of the first direction. For example, the first direction can be... Figure 3 The x-direction shown can be followed by a second direction. Figure 3 The y direction shown in .

[0060] The electrodes may include a first type of electrode 21, a second type of electrode 22, and a third type of electrode 23. These electrodes are arranged sequentially along a second direction within the touch area 11, with the second type of electrode 22 located between the first type of electrode 21 and the third type of electrode 23. The area occupied by the first type of electrode 21 and the second type of electrode 22 in the touch area 11 is equal to the area occupied by the third type of electrode 23 in the touch area 11, or the area occupied by the second type of electrode 22 and the third type of electrode 23 in the touch area 11 is equal to the area occupied by the first type of electrode 21 in the touch area 11. However, this disclosure is not limited to this; the area occupied by the first type of electrode 21 in the touch area 11 may also be equal to the area occupied by the third type of electrode 23 in the touch area 11.

[0061] A first type of electrode 21 is connected to a first type of wire 30, a second type of electrode 22 is connected to a first type of wire 30 and a second type of wire 40, and a third type of electrode 23 is connected to a second type of wire 40. The first type of wire 30 and the second type of wire 40 can be connected to the same end of the second type of electrode 22. The processing component 50 conducts two different wires to connect the electrodes connected to the wires, forming coils. The processing component 50 can conduct different combinations of wires to form different coils at different positions in the touch area 11, thereby obtaining touch positioning information based on the coil position and electromagnetic induction signal.

[0062] When the processing component 50 forms a coil by passing through the conductive wires and electrodes, the processing component 50 can conduct two of the first type of wires 30 to conduct the two electrodes connected to the first type of wires 30 and form a coil. Since the two first type of wires 30 extend in the same direction and are connected to the processing component 50, the closed coil formed by the electrodes and wires can cover the area between the two electrodes and can well receive the signal emitted by the electromagnetic induction signal source in the vicinity of this area.

[0063] The processing component 50 can also conduct two of the second type of wires 40 to conduct the two electrodes connected to the second type of wires 40 and form a coil. Since the two second type of wires 40 extend in the same direction and are connected to the processing component 50, the formed closed coil can cover the area between the two electrodes and can receive signals emitted by electromagnetic induction signal sources in the vicinity of this area.

[0064] When the touch panel needs to form multiple coils at the same time, the processing component 50 can conduct two of the first type of wires 30 and two of the second type of wires 40. That is, the processing component 50 can conduct two wires with the same extension direction and combine them with the electrodes connected to the wires to form a closed coil. The closed coil can cover the area between the two electrodes.

[0065] This disclosure provides a second type electrode 22 between a first type electrode 21 connected only to a first type wire 30 and a third type electrode 23 connected only to a second type wire 40, and connects the second type electrode 22 to both the first type wire 30 and the second type wire 40. This allows the second type electrode 22 to form a closed coil by combining with the first type electrode 21 through the first type wire 30, and also to form a closed coil by combining with the third type electrode 23 through the second type wire 40. This avoids the situation where the first type electrode 21 and the third type electrode 23 adjacent to the third type electrode 23 need to surround the touch area 11 to form a closed coil structure that is different from the coil structure formed in other areas. Thus, a closed coil can be formed by connecting two first type wires 30 through the first type electrode 21 and the second type electrode 22, or by connecting two second type wires 40 through the second type electrode 22 and the third type electrode 23, making the coil structures formed by multiple electrodes and wires in all touch areas of the touch area 11 consistent.

[0066] This disclosure effectively solves the problem of inconsistent coil structures in specific areas of the touch area, such as the middle area, compared to other areas, caused by all electrodes having wires connected in only one direction. This is achieved by adding a second type of electrode 22 between the first type of electrode 21 and the third type of electrode 23, which can connect wires in opposite directions. This enhances the electromagnetic induction signal reception capability of the coils formed in the touch area 11, improves the consistency of electromagnetic induction signal reception capabilities of different coils, improves the linearity of electromagnetic induction signal reception by the touch panel, and improves the accuracy of touch positioning. Furthermore, when the coils can also be used to emit electromagnetic induction signals to the outside world, the emission capability of electromagnetic induction signals from different coils can be improved, enhancing the consistency of signals emitted by the touch panel.

[0067] In some embodiments, such as Figure 3 As shown, the processing component 50 can be configured to conduct two electrodes spaced P electrodes apart among multiple electrodes and form a coil, where P is greater than or equal to 0, and the number of second-type electrodes 22 is greater than or equal to P+1.

[0068] When the processing component 50 forms different coils, it will make the two electrodes forming the coil spaced P electrodes apart.

[0069] When the number of second-type electrodes 22 is configured to be greater than or equal to P+1, the first-type electrode 21 closest to the second-type electrode 22 can form a coil with the second-type electrode 22 spaced P times apart, i.e., the P+1th second-type electrode 22. The third-type electrode 23 closest to this first-type electrode 21 is spaced P+1 times apart from this first-type electrode 21. Therefore, the first-type electrode 21 and the third-type electrode 23 will not conduct and form a coil, thus avoiding the situation where the first-type electrode 21 and the third-type electrode 23 conduct and form a coil that needs to surround the touch area 11, and causing the coil structure to be inconsistent with the coil structure of other areas. This makes the coil structures formed by multiple electrodes and wires consistent, 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 receiving electromagnetic induction signals, and improves the accuracy of touch positioning.

[0070] In some embodiments, P can be any integer from 1 to 3. For example, P can be 2. When the value of P is greater than the above range, the area of ​​the coil formed by the electrodes and wires will be too large, resulting in a decrease in the energy intensity that the coil can receive. It will also make the corresponding area of ​​the coil and the touch area 11 too large, reducing the positioning accuracy of the coil for the electromagnetic induction signal, making it difficult to obtain a precise touch position through the coil. When the value of P is less than the above range, if the electromagnetic induction signal source moves rapidly, the electromagnetic induction signal source may move out of the area range of a single coil, resulting in the loss of touch positioning information. However, this disclosure is not limited to this. The specific value of P can be changed according to the spacing between the electrodes and the specific application scenario.

[0071] Figure 4 This is a schematic diagram illustrating the positioning principle of a touch panel provided in an embodiment of this disclosure.

[0072] In some embodiments, such as Figure 3 and Figure 4 As shown, there can be a gap of 2 electrodes between the two electrodes forming the coil, P+1 can be 3, and the number of second-type electrodes 22 is 3. When the processing component 50 conducts the Nth electrode of the first-type electrodes 21 that is closest to the third-type electrode 23, the Nth electrode can conduct with the Mth electrode that is spaced P electrodes apart and form a closed coil. The Mth electrode is the P+1th second-type electrode 22. Therefore, the electrode of the first-type electrodes 21 that is closest to the third-type electrode 23 can conduct with the second-type electrode 22 to form a coil. And by conducting the first-type wire 30 of the Nth electrode and the first-type wire 30 of the Mth electrode, an effective closed coil can be formed, covering the area between the Nth electrode and the Mth electrode.

[0073] In some embodiments, the processing component 50 can connect a first type of wire 30 connected to a first type of electrode 21 and a first type of wire 30 connected to another electrode to control the first type of electrode 21 and the other electrode to conduct and form a coil, wherein the other electrode is the first type of electrode 21 and the second type of electrode 22. The fact that the other electrode is the first type of electrode 21 and the second type of electrode 22 means that the first type of electrode 21 can conduct and form a coil with the first type of electrode 21 through the first type of wire 30, and the first type of electrode 21 can also conduct and form a coil with the second type of electrode 22 through the first type of wire 30.

[0074] Furthermore, the processing component 50 can also connect the second type wire 40 connected to the third type electrode 23 and the second type wire 40 connected to another electrode, to control the third type electrode 23 and the other electrode to conduct and form a coil, wherein the other electrode is the second type electrode 22 and the third type electrode 23. The fact that the other electrode is the second type electrode 22 and the third type electrode 23 means that the third type electrode 23 can conduct and form a coil with the second type electrode 22 through the second type wire 40, and the third type electrode 23 can also conduct and form a coil with the third type electrode 23 through the second type wire 40.

[0075] By enabling the first type of electrode 21 to conduct with both the first type of electrode 21 with the first type of wire 30 and the second type of electrode 22 with the first type of wire 30, and enabling the third type of electrode 23 to conduct with both the second type of electrode 22 with the second type of wire 40 and the third type of electrode 23 with the second type of wire 40, the coil structure formed by the electrodes and wires can be made consistent. This 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 receiving electromagnetic induction signals, and improves the accuracy of touch positioning.

[0076] In some embodiments, the processing component 50 can connect a first type of wire 30 connected to a first type of electrode 21 and a first type of wire 30 connected to another electrode to control the first type of electrode 21 and the other electrode to conduct 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 connect a second type of wire 40 connected to a third type of electrode 23 and a second type of wire 40 connected to another electrode to control the third type of electrode 23 and the other electrode to conduct and form a coil, wherein the other electrode is the second type of electrode 22 and the third type of electrode 23.

[0077] Furthermore, the processing component 50 can also connect wires extending in the same direction to the second type of electrodes 22 spaced P apart, to control the conduction between the second type of electrodes 22 spaced P apart and form a coil. For example, the processing component 50 can connect a first type of wire 30 to two second type of electrodes 22 spaced P apart, so that the two second type of electrodes 22 spaced P apart are connected and form a coil. The processing component 50 can also connect a second type of wire 40 or a first type of wire 30 to two second type of electrodes 22 spaced P apart, so that the two second type of electrodes 22 spaced P apart are connected and form a coil.

[0078] In this embodiment, while ensuring that the coil structures formed by the electrodes and wires are consistent to improve the consistency of electromagnetic induction signal reception capabilities of different coils, the second type of electrode 22 can also be connected with another second type of electrode 22 spaced P times apart to form a coil, thereby increasing the coverage density of the coil on the touch panel and improving the accuracy of touch positioning.

[0079] In some embodiments, when the processing component 50 controls the conduction between the second type of electrodes 22 spaced P times apart to form a coil, the number of the second type of electrodes 22 is at least 2 more than the number of P. For example, when the number of the second type of electrodes 22 is 3 and P is 1, the two second type of electrodes 22 spaced 1 time apart conduction to form a coil.

[0080] In some embodiments, the number of second-type electrodes 22 can be equal to P+1. When the number of second-type electrodes 22 is P+1, the electrodes separated from the second-type electrodes 22 by P electrodes are either first-type electrodes 21 or third-type electrodes 23. In this case, the second-type electrodes 22 are only connected to the first-type electrodes 21 or third-type electrodes 23 to form a coil. This allows the second-type electrodes 22 to meet the requirement of the first-type electrodes 21 and third-type electrodes 23 being connected to the second-type electrodes 22 and forming coils with the same structure with the minimum number of electrodes. This reduces the total number of second-type electrodes 22, thereby reducing the setup cost of the touch panel. For example, if P is 2 and the number of second-type electrodes 22 is 3, the second-type electrodes 22 will not be connected to each other. This will result in first-type electrodes 21 being connected by a 2-electrode gap, third-type electrodes 23 being connected by a 2-electrode gap, second-type electrodes 22 being connected to first-type electrodes 21 by a 2-electrode gap, and / or second-type electrodes 22 being connected to third-type electrodes 23 by a 2-electrode gap. All the connected electrodes form coils with the same structure.

[0081] Figure 5 This is a schematic diagram of the structure of a touch panel provided in an embodiment of this disclosure.

[0082] In some embodiments, such as Figure 5As shown, the second type of electrode 22 may include a first sub-electrode 221 and a second sub-electrode 222, wherein the first sub-electrode 221 may be adjacent to the first type of electrode 21, and the second sub-electrode 222 may be adjacent to the third type of electrode 23. When the number of second type electrodes 22 is greater than P+1, there may be a gap of P electrodes between the first sub-electrode 221 and the second sub-electrode 222.

[0083] The processing component 50 can conduct the first type of wire 30 connected to the first sub-electrode 221 and the first type of wire 30 connected to the second sub-electrode 222 to conduct the first sub-electrode 221 and the second sub-electrode 222 and form a coil.

[0084] The processing component 50 can also conduct the second type of wire 40 connected to the first sub-electrode 221 and the second type of wire 40 connected to the second sub-electrode 222 to conduct the first sub-electrode 221 and the second sub-electrode 222 and form a coil.

[0085] Through the above-described conduction configuration, the processing component 50 can make the first sub-electrode 221 and the second sub-electrode 222 conduct and form a closed coil, avoiding the wires with opposite conduction directions of the first sub-electrode 221 and the second sub-electrode 222, making the coil structures formed by multiple electrodes and wires consistent, enhancing the electromagnetic induction signal receiving capability of the coil formed in the touch area 11, improving the consistency of the electromagnetic induction signal receiving capability of different coils, improving the linearity of the touch panel receiving electromagnetic induction signals, and improving the accuracy of touch positioning.

[0086] In some embodiments, such as Figure 3 As shown, the extension directions of the multiple electrodes are parallel to each other.

[0087] Each of the first type of conductors 30 may include a first extension segment 31, which may be connected to a first type of electrode 21 or a second type of electrode 22. The first extension segment 31 extends from either the first type of electrode 21 or the second type of electrode 22 into the touch area 11. The extension direction of the first extension segment 31 is parallel to the extension direction of the multiple electrodes. The length of the multiple first extension segments 31 gradually increases along the second direction, so that each first type of conductor 30 has a different spacing from the edge of the touch area 11 when extending along the first direction. Furthermore, the spacing between the first type of conductor 30 and the edge of the touch area 11 gradually increases along the second direction, so that the first type of conductor 30 closer to the third type of electrode 23 is routed on the periphery, avoiding the intersection of the first type of conductor 30 closer to the third type of electrode 23 and the first type of conductor 30 farther away from the third type of electrode 23, thus reducing the possibility of intersection of the routing paths between multiple first type of conductors 30.

[0088] Each of the second type of conductors 40 may include a second extension segment 41, which may be connected to the second type of electrode 22. The first extension segment 31 may also be connected to the third type of electrode 23. The second extension segment 41 extends from the second type of electrode 22 or the third type of 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 length of the multiple second extension segments 41 gradually increases along the first direction, so that each second type of conductor 40 has a different spacing from the edge of the touch area 11 when extending along the second direction. The spacing between the second type of conductor 40 and the edge of the touch area 11 gradually increases along the first direction, so that the second type of conductor 40 closer to the first type of electrode 21 is routed on the periphery, avoiding the intersection of the second type of conductor 40 close to the first type of electrode 21 and the second type of conductor 40 far away from the first type of electrode 21, and reducing the possibility of intersection of the routing paths between multiple second type of conductors 40.

[0089] The above configuration can reduce the crossover of the routing paths between the first type of conductors 30 and the second type of conductors 40, thereby reducing the additional costs caused by the crossover of the conductors and reducing crosstalk between the conductors to ensure the touch performance of the touch panel.

[0090] In some embodiments, such as Figure 3 As shown, the touch panel may include a bus 32, which may be connected to a second type of electrode 22. At least a portion of the bus 32 may form a first extension 31, and at least a portion of the bus 32 may also form a second extension 41.

[0091] 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. This reduces the number of wires directly connected to a single second type of electrode 22, reduces the difficulty of connecting multiple wires to the second type of electrode 22, reduces the wiring space occupied by the two wires connected to the second type of electrode 22, and simplifies 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.

[0092] However, this disclosure is not limited thereto, and the first extension 31 and the second extension 41 may also be connected to the same end of the same second type electrode 22.

[0093] Figure 6 This is a schematic diagram of the structure of a touch panel with a substrate provided in an embodiment of this disclosure.

[0094] In some embodiments, such as Figure 6 As shown, the touch panel may include a substrate 10, and a touch area 11, a first type of wire 30, and a second type of wire 40 may be disposed on the substrate 10.

[0095] The substrate 10 can be the skeleton structure of the touch panel, providing routing space for the first type of wires 30 and the second type of wires 40, and providing mounting and fixing for the electrodes.

[0096] Since the second type electrode 22 is connected to the first type wire 30 and the second type wire 40, and there are multiple second type electrodes 22, the routing paths of the first type wire 30 and the second type wire 40 have routing intersections.

[0097] The touch panel may include an insulating layer located at the intersection of the traces and may be disposed between the first type of conductor 30 and the second type of conductor 40. For example, the first type of conductor 30 may include a metal connecting bridge, which can cross the second type of conductor 40. An insulating layer may be disposed between the metal connecting bridge and the second type of conductor 40 at the intersection. This can prevent short circuits between the first type of conductor 30 and the second type of conductor 40 at the intersection without increasing the area of ​​the substrate 10, allowing the first type of conductor 30 and the second type of conductor 40 to cross and ensure signal transmission performance.

[0098] In other embodiments, the substrate 10 may also be provided with vias that penetrate the substrate 10. The vias can be used to allow the first type of conductor 30 and the second type of conductor 40 to extend to different surfaces of the substrate 10 for routing. This can prevent short circuits between the first type of conductor 30 and the second type of conductor 40 at the routing intersection without increasing the area of ​​the substrate 10, and enable the first type of conductor 30 and the second type of conductor 40 to cross routing, thus ensuring the performance of signal transmission.

[0099] In some embodiments, an insulating layer can be provided between the first type of conductor 30 and the second type of conductor 40, and a via can be provided through the substrate 10. This can prevent short circuits between the first type of conductor 30 and the second type of conductor 40 at the intersection of the traces without increasing the area of ​​the substrate 10, and enable the first type of conductor 30 and the second type of conductor 40 to cross the traces, thus ensuring the performance of signal transmission.

[0100] In some embodiments, such as Figure 3As shown, the multiple electrodes also include a fourth type of electrode 24. The extension direction of the fourth type of electrode 24 can be perpendicular to the extension direction of the first type of electrode 21, and the multiple fourth type of electrodes 24 can be arranged in a direction perpendicular to the first direction. The first type of electrode 21, the second type of electrode 22, and the third type of electrode 23 are used to detect touch information in the first direction. The fourth type of electrode 24 is based on the same or similar principle as the first type of electrode 21, the second type of electrode 22, and the third type of electrode 23, and is used to detect touch information in a direction perpendicular to the first direction. By obtaining touch information, including position coordinates, in two mutually perpendicular directions, the position positioning of the touch accessory can be achieved.

[0101] Based on the same concept, this disclosure also provides a touch device, which may include a touch panel. The touch device can receive electromagnetic induction signals emitted by a touch accessory by exciting different coils formed by electrodes on the excitation panel, and then obtain the positioning information of the touch accessory by obtaining the electromagnetic induction signals obtained by the different coils.

[0102] Figure 7 This is a flowchart of a control method for a touch panel provided in an embodiment of this disclosure.

[0103] Based on the same concept, this disclosure also provides a method for controlling a touch panel, such as... Figure 7 As shown, the control method may include the following steps:

[0104] S10: According to the pre-stored correspondence between coils and wires, 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, so as to control the Nth electrode and the Mth electrode to conduct and form a coil, and obtain the electromagnetic induction signal received by the coil.

[0105] S20: Control N to increment from 1, forming multiple coils in sequence, so as to obtain the electromagnetic induction signals of multiple coils respectively;

[0106] S30: Obtain touch positioning information based on the electromagnetic induction signals received by each coil.

[0107] Where M and N are both positive integers, and MN is greater than or equal to 1;

[0108] The first type of conductor extends along the first direction, the second type of conductor extends along the second direction, and the Nth electrode and the Mth electrode are arranged sequentially along the second direction.

[0109] When the touch panel needs to activate a specific coil, it can activate the corresponding two wires according to the pre-stored correspondence between coils and wires, thereby activating the specific coil.

[0110] Subsequently, a closed coil can be formed by connecting the first type of wires of the Nth and Mth electrodes, or a closed coil can be formed by connecting the second type of wires of the Nth and Mth electrodes. By connecting wires extending in the same direction, the opening structure between the two wires can be closed, thereby forming a closed coil. Furthermore, by incrementing N from 1, the electrodes of the touch area are sequentially formed into coils, and the coils cover different positions of the touch area, thereby achieving scanning of the touch area. For example, N can be 1, 2, 3, 4, 5, 6 in sequence, and M can be 4, 5, 6, 7, 8, 9 in sequence.

[0111] Touch positioning information can be obtained by processing the electromagnetic induction signals received by multiple coils at different locations.

[0112] This disclosure, by connecting wires extending in the same direction, can close the opening structure between two wires, thereby forming a closed coil. This improves the electromagnetic induction signal receiving capability of the coil and avoids connecting first-type and second-type wires extending in opposite directions. This avoids the situation where the electrodes and wires need to form a coil around the touch area after being connected, resulting in a coil structure inconsistent with the coil structure in other areas. This ensures 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 in receiving electromagnetic induction signals, and improving the accuracy of touch positioning.

[0113] Figure 8 This is a flowchart of a control method for a touch panel provided in an embodiment of this disclosure.

[0114] In some embodiments, such as Figure 8 As shown, the control method may include the following steps:

[0115] S11: Based on the fact that the Nth electrode is a first type electrode, conduct 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 and form a coil, and obtain the electromagnetic induction signal received by the coil, wherein the Mth electrode is a first type electrode or a second type electrode.

[0116] S12: Based on the fact that the Mth electrode is a third type electrode, conduct the second type wire connected to the Nth electrode and the second type wire connected to the Mth electrode to control the Mth electrode and the Nth electrode to form a coil, and obtain the electromagnetic induction signal received by the coil, wherein the Nth electrode is a second type electrode or a third type electrode.

[0117] S20: Control N to increment from 1, forming multiple coils in sequence, so as to obtain the electromagnetic induction signals of multiple coils respectively;

[0118] S30: Obtain touch positioning information based on the electromagnetic induction signals received by each coil.

[0119] The touch panel includes multiple electrodes, which include a first type of electrode, a second type of electrode, and a third type of electrode arranged sequentially along a second direction. The first type of electrode is connected to a first type of wire, the second type of electrode is connected to a first type of wire and a second type of wire, and the third type of electrode is connected to a second type of wire.

[0120] Based on the pre-stored correspondence between coils and wires, the first type of electrode can be connected to either the first or second type of electrode, and the third type of electrode can be connected to either the second or third type of electrode. This configuration avoids connecting the first and second type of wires extending in opposite directions, ensuring that the coils formed by each electrode can form closed coils with a consistent structure. This improves the consistency of electromagnetic induction signal reception capabilities of different coils and enhances the linearity of the touch panel's electromagnetic induction signal reception.

[0121] This disclosure provides a second type of electrode by placing it between a first type of electrode connected only to a first type of wire and a third type of electrode connected only to a second type of wire, and connecting the second type of electrode to both the first and second type of wires. This allows the second type of electrode to form a closed coil by combining with the first type of electrode through the first type of wire, and also to form a closed coil by combining with the third type of electrode through the second type of wire. This avoids the situation where the first type of electrode adjacent to the third type of electrode forms a coil that needs to surround the touch area after being connected, resulting in an inconsistent coil structure with the coil structure in other areas. Thus, a closed coil can be formed by connecting two first type of wires and two second type of wires, making the coil structures formed by multiple electrodes and wires consistent. This enhances the electromagnetic induction signal receiving capability of the coils formed in the touch area, improves the consistency of the electromagnetic induction signal receiving capability of different coils, improves the linearity of the touch panel in receiving electromagnetic induction signals, and improves the accuracy of touch positioning.

[0122] Figure 9 This is a flowchart of a control method for a touch panel provided in an embodiment of this disclosure.

[0123] In some embodiments, such as Figure 9 As shown, the control method may include the following steps:

[0124] S11: Based on the fact that the Nth electrode is a first type electrode, conduct 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 and form a coil, and obtain the electromagnetic induction signal received by the coil, wherein the Mth electrode is a first type electrode or a second type electrode.

[0125] S12: Based on the fact that the Mth electrode is a third type electrode, conduct the second type wire connected to the Nth electrode and the second type wire connected to the Mth electrode to control the Mth electrode and the Nth electrode to conduct and form a coil, and obtain the electromagnetic induction signal received by the coil, wherein the Nth electrode is a second type electrode or a third type electrode.

[0126] S13: Since both the Nth electrode and the Mth electrode are second-type electrodes, conduct the wires that extend in the same direction connected to the Nth electrode and the Mth electrode;

[0127] S20: Control N to increment from 1, forming multiple coils in sequence, so as to obtain the electromagnetic induction signals of multiple coils respectively;

[0128] S30: Obtain touch positioning information based on the electromagnetic induction signals received by each coil.

[0129] Based on the pre-stored correspondence between coils and wires, the first type of electrode can be connected to the first type of electrode or the second type of electrode, and the third type of electrode can be connected to the second type of electrode or the third type of electrode. This configuration avoids connecting the first type of wire and the second type of wire extending in opposite directions, thus preventing the formation of a coil that needs to surround the touch area after the electrodes and wires are connected, and avoiding inconsistencies between the coil structure and the coil structure in other areas.

[0130] Furthermore, when both the Nth and Mth electrodes are of the second type, the Nth and Mth electrodes can be connected to wires with the same extension direction, avoiding the first and second sub-electrodes from being connected to wires with opposite extension directions. This avoids the formation of coils around the touch area after the electrodes and wires are connected, which would lead to inconsistencies between the coil structure and the coil structure in other areas. This ensures that the coil structures formed by multiple electrodes and wires are consistent, enhancing the electromagnetic induction signal reception capability of the coils formed in the touch area, improving the consistency of electromagnetic induction signal reception capability of different coils, improving the linearity of the touch panel in receiving electromagnetic induction signals, and improving the accuracy of touch positioning.

[0131] This disclosure provides a second type of electrode by placing it between a first type of electrode connected only to a first type of wire and a third type of electrode connected only to a second type of wire, and connecting the second type of electrode to both the first and second type of wires. This allows the second type of electrode to form a closed coil by combining with the first type of electrode through the first type of wire, and also to form a closed coil by combining with the third type of electrode through the second type of wire. This avoids the situation where the first type of electrode adjacent to the third type of electrode forms a coil that needs to surround the touch area, resulting in an inconsistent coil structure with the coil structure in other areas. Thus, a closed coil can be formed by connecting two first type of wires and two second type of wires, making the coil structures formed by multiple electrodes and wires consistent. This enhances the electromagnetic induction signal receiving capability of the coils formed in the touch area, improves the consistency of the electromagnetic induction signal receiving capability of different coils, improves the linearity of the touch panel in receiving electromagnetic induction signals, and improves the accuracy of touch positioning.

[0132] Figure 10 This is a flowchart of a control method for a touch panel provided in an embodiment of this disclosure.

[0133] In some embodiments, such as Figure 10 As shown, the control method may include the following steps:

[0134] S10: According to the pre-stored correspondence between coils and wires, 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, so as to control the Nth electrode and the Mth electrode to conduct and form a coil, and obtain the electromagnetic induction signal received by the coil.

[0135] S20: Control N to increment from 1, forming multiple coils in sequence, so as to obtain the electromagnetic induction signals of multiple coils respectively;

[0136] S31: Based on the electromagnetic induction signals received by each coil, obtain the curve showing the correspondence between the intensity of the electromagnetic induction signal and the coordinates of the touch area;

[0137] S32: Determine the coordinates of the touch area corresponding to the highest point of the corresponding relationship curve;

[0138] S33: Obtain touch positioning information based on the touch area coordinates corresponding to the highest point of the corresponding relationship curve.

[0139] When the touch panel needs to activate a specific coil, it can activate the corresponding two wires according to the pre-stored correspondence between coils and wires, thereby activating the specific coil.

[0140] Subsequently, a closed coil can be formed by connecting the first type of wires of the Nth and Mth electrodes, or a closed coil can be formed by connecting the second type of wires of the Nth and Mth electrodes. By connecting wires extending in the same direction, the opening structure between the two wires can be closed, thereby forming a closed coil. Furthermore, by incrementing N from 1, the electrodes of the touch area are sequentially formed into coils, and the coils cover different positions of the touch area, thereby achieving scanning of the touch area.

[0141] Based on the electromagnetic induction signal intensity received by multiple coils at different locations, a curve showing the correspondence between the electromagnetic induction signal intensity and the coordinates of the touch area can be obtained. The highest point of the curve represents the highest electromagnetic induction signal intensity received by the corresponding coil, which is closest to the touch accessory that serves as the emission source. Therefore, the touch accessory can be considered to be located at the position of the coil corresponding to the highest point of the curve, thereby obtaining touch positioning information.

[0142] This disclosure, by connecting wires extending in the same direction, can close the opening structure between two wires, thereby forming a closed coil. This enhances the electromagnetic induction signal receiving capability of the coil and avoids connecting first-type and second-type wires extending in opposite directions. This prevents the formation of a coil that needs to surround the touch area after the electrodes and wires are connected, thus avoiding inconsistencies in coil structure with coil structures in other areas. It ensures 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. This makes the electromagnetic induction signal receiving capabilities of multiple coils similar, improving the consistency of electromagnetic induction signal receiving capabilities of different coils and enhancing the linearity of electromagnetic induction signal reception by the touch panel. Consequently, the intensity of the electromagnetic induction signal received by the coil is more inversely proportional to the distance between the coil and the touch accessory, improving the accuracy of touch positioning.

[0143] Figure 11 This is a block diagram of a control device for a touch panel provided in an embodiment of this disclosure.

[0144] Based on the same concept, this disclosure also provides a control device for a touch panel, such as... Figure 11As shown, the control device may include: an execution unit 60, which is configured to, according to a pre-stored correspondence between coils and wires, conduct a first type of wire connected to the Nth electrode and a first type of wire connected to the Mth electrode, and conduct a second type of wire connected to the Nth electrode and a second type of wire connected to the Mth electrode, so as to control the Nth electrode and the Mth electrode to conduct and form a coil, and acquire the electromagnetic induction signal received by the coil; control N to increment from 1 to sequentially form multiple coils, so as to acquire the electromagnetic induction signals of multiple coils respectively; and a processing unit 70, which is configured to obtain touch positioning information according to the electromagnetic induction signals received by each coil, wherein M and N are both positive integers, and MN is greater than or equal to 1; the first type of wire extends along a first direction, the second type of wire extends along a second direction, and the Nth electrode and the Mth electrode are arranged sequentially along the second direction.

[0145] In some embodiments, the touch panel includes a plurality of electrodes, the plurality of electrodes including a first type electrode, a second type electrode, and a third type electrode arranged sequentially along a second direction, the first type electrode being connected to a first type wire, the second type electrode being connected to a first type wire and a second type wire, and the third type electrode being connected to a second type wire. The execution unit 60 is further configured to: based on the Nth electrode being a first type electrode, conduct 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 and form a coil, wherein the Mth electrode is a first type electrode or a second type electrode; based on the Mth electrode being a third type electrode, conduct the second type wire connected to the Nth electrode and the second type wire connected to the Mth electrode to control the Mth electrode and the Nth electrode to conduct and form a coil, wherein the Nth electrode is a second type electrode or a third type electrode.

[0146] In some embodiments, the execution unit 60 is further configured to: conduct wires with the same extension direction connected to the Nth electrode and the Mth electrode, and form a coil, based on the fact that both the Nth electrode and the Mth electrode are second type electrodes.

[0147] In some embodiments, the execution unit 60 obtains touch positioning information based on the electromagnetic induction signals received by each coil in the following manner: obtaining a correspondence curve between the intensity of the electromagnetic induction signal and the coordinates of the touch area based on the electromagnetic induction signals received by each coil; determining the coordinates of the touch area corresponding to the highest point of the correspondence curve; and obtaining touch positioning information based on the coordinates of the touch area corresponding to the highest point of the correspondence curve.

[0148] Regarding the apparatus in the above embodiments, the specific manner in which each unit or module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0149] Figure 12This is a schematic diagram of an electronic device provided in an embodiment of this disclosure.

[0150] Based on the same concept, such as Figure 12 As shown, one embodiment of this disclosure provides an electronic device 300. The electronic device 300 includes a memory 301, a processor 302, and an input / output (I / O) interface 303. The memory 301 is used to store instructions. The processor 302 is used to execute the touch panel control method of this disclosure embodiment by calling the instructions stored in the memory 301. The processor 302 is connected to both the memory 301 and the I / O interface 303, for example, via a bus system and / or other forms of connection mechanism (not shown). The memory 301 can be used to store programs and data, including the program for the touch panel control method involved in the embodiments of this disclosure. The processor 302 executes various functional applications and data processing of the electronic device 300 by running the program stored in the memory 301.
