The electromagnetic handwriting board can be matched with an electromagnetic pen. The electromagnetic handwriting board can comprise a transmitting coil and a receiving coil, the transmitting coil can send electromagnetic waves to the electromagnetic pen, a resonant circuit in the electromagnetic pen can vibrate and continuously attenuate after receiving the electromagnetic waves, and the receiving coil receives vibration signals sent by the electromagnetic pen, so that coordinate positioning and data transmission of the electromagnetic pen are realized.

Fig. 1 is a schematic structural diagram of a touch panel according to the related art. Fig. 2 is a schematic diagram of a positioning principle of a touch panel according to the related art.

In the related art, as shown in fig. 1, the touch panel is provided with a plurality of electrodes arranged in a first direction, and the electrodes may include a first type electrode 21 and a third type electrode 23, and the first type electrode 21 and the third type electrode 23 are sequentially arranged in a second direction. Wherein the first direction and the second direction may be opposite directions. Illustratively, the first direction may be the X direction illustrated in fig. 1, and the second direction may be the Y direction illustrated in fig. 1.

The first type of electrode 21 may be coupled to a first type of wire 30, the first type of wire 30 extending circumferentially in a first direction to be coupled to the processing assembly 50, and the third type of electrode 23 may be coupled to a second type of wire 40 extending circumferentially in a second direction to be coupled to the processing assembly 50. The processing assembly 50 may conduct the first electrode from the left in fig. 1 and the fourth electrode from the left in fig. 1 by conducting two of the plurality of electrodes such that the electrodes and the wires connected thereto form a coil, and the processing assembly 50 may illustratively conduct the first electrode from the left in fig. 1 and the fourth electrode from the left in fig. 1, both electrodes extending in the first direction through the first type of wire 30, the coil formed by the two electrodes covering the area between the two electrodes such that the coil is capable of well receiving electromagnetic induction signals located in this area.

Wherein, in the process of composing different coils, the part of the first type electrode 21 adjacent to the third type electrode 23 needs to form coils with the third type electrode 23. When the processing component 50 controls the nth electrode of the first type of electrodes 21 and the mth electrode of the third type of electrodes 23 to be conducted and form a coil, as shown in fig. 2, for example, the nth electrode may be the 4 th electrode from the left in fig. 2, and the mth electrode may be the 7 th electrode from the left in fig. 2, because the first type of wires 30 and the second type of wires 40 extend oppositely, the first type of wires 30 need to extend around one side of the touch area and are connected with the processing component 50, the second type of wires 40 need to extend around the other side of the touch area and are connected with the processing component 50, the first type of wires 30 and the second type of wires 40 are connected with the processing component 50, which makes the coil formed by the first type of wires 30, the second type of wires 40 and the corresponding connected electrodes have different coil structures from other coil structures formed by conducting only the first type of wires 30 or conducting only the second type of wires 40, which makes the coil unable to well receive signals sent by the electromagnetic induction signal sources adjacent to the area between the two electrodes, which causes the coil and other coil to extend around one side of the touch area and connect with the other coil, the other coil to extend around the other side of the touch area, and the electromagnetic induction signal is not connected with the other coil, and the touch area is formed by the touch area, and the electromagnetic induction signal is reduced. Moreover, in the case of a narrow bezel of the touch panel, the wiring space of the bezel is narrow, and the wiring of the coil is limited.

Based on the same principle, when the coils are also used for transmitting signals, the coil structures with differences can also cause different signal transmitting capacities of different coils, so that the consistency of signals transmitted by the touch panel is reduced.

In order to solve the above technical problems, embodiments according to the present disclosure provide a touch panel, a touch device, a control method, an electronic apparatus, and a storage medium.

In some embodiments, as shown in FIG. 3, the touch panel may include a touch area 11, a processing component 50, and a plurality of electrodes, which may be located within the touch area 11.

The touch area 11 is an area of the touch panel for recognizing a touch signal, and the processing component 50 is used for forming a coil by conducting different electrodes to receive an electromagnetic induction signal and obtain touch positioning information. The present disclosure is not limited thereto and the coil may also be used to transmit electromagnetic induction signals to the outside.

The touch panel further includes a first type of conductive line 30 and a second type of conductive line 40. The first type of conductive lines 30 may be led out from the touch area 11, surround the touch area 11 along the first direction, and connect with the processing component 50. The second type of conductive lines 40 may be led out from the touch area 11, surround the touch area 11 along the second direction, and connect with the processing unit 50.

The second direction may be the opposite direction of the first direction. Illustratively, the first direction may be the x-direction shown in fig. 3 and the second direction may be the y-direction shown in fig. 3.

The electrodes may include a first type of electrode 21, a second type of electrode 22, and a third type of electrode 23, where the first type of electrode 21, the second type of electrode 22, and the third type of electrode 23 are sequentially arranged in the touch area 11 along a second direction, that is, the second type of electrode 22 is located between the first type of electrode 21 and the third type of electrode 23. The area occupied by the first type electrode 21 and the second type electrode 22 in the touch area 11 is equal to the area occupied by the third type electrode 23 in the touch area 11, or the area occupied by the second type electrode 22 and the third type electrode 23 in the touch area 11 is equal to the area occupied by the first type electrode 21 in the touch area 11, but the present disclosure is not limited thereto, and may be that the area occupied by the first type electrode 21 in the touch area 11 is equal to the area occupied by the third type electrode 23 in the touch area 11.

The first type electrode 21 is connected with a first type wire 30, the second type electrode 22 is connected with a first type wire 30 and a second type wire 40, and the third type electrode 23 is connected with a second type wire 40, wherein the first type wire 30 and the second type wire 40 can be connected to the same end of the second type electrode 22. The processing assembly 50 turns on the electrodes connected to the wires by turning on two different wires and forms a coil. The processing component 50 can conduct different wire combinations, so as to form different coils at different positions of the touch area 11, and further obtain touch positioning information according to the positions of the coils and electromagnetic induction signals.

When the processing assembly 50 forms a coil by conducting the wires and the electrodes, the processing assembly 50 can conduct two of the first type wires 30 to conduct two electrodes connected with the first type wires 30 and form a coil, and since the two first type wires 30 extend in the same direction and are connected with the processing assembly 50, the closed coil formed by the electrodes and the wires can cover the area between the two electrodes and can well receive signals sent by electromagnetic induction signal sources adjacent to the area.

The processing assembly 50 may also conduct two of the second type of wires 40 to conduct two electrodes connected to the second type of wires 40 and form a coil, and since the two second type of wires 40 extend in the same direction and are connected to the processing assembly 50, the formed closed coil can cover the area between the two electrodes and can well receive signals sent by electromagnetic induction signal sources adjacent to the area.

When the touch panel needs to form a plurality of coils at the same time, the processing component 50 may conduct two of the first type of wires 30 and conduct two of the second type of wires 40, that is, the processing component 50 may conduct two wires with the same extending direction and form a closed coil in combination with the electrodes connected to the wires, and the closed coil may cover the area between the two electrodes.

The second type electrode 22 is arranged between the first type electrode 21 connected with the first type wire 30 and the third type electrode 23 connected with the second type wire 40, and the second type electrode 22 is connected with both the first type wire 30 and the second type wire 40, so that the second type electrode 22 can be combined with the first type electrode 21 to form a closed coil through conducting the first type wire 30, and can also be combined with the third type electrode 23 to form a closed coil through conducting the second type wire 40, the condition that the first type electrode 21 and the third type electrode 23 adjacent to the third type electrode 23 need to encircle the touch area 11 and the formed closed coil structure is different from the coil structure formed by other areas is avoided, and therefore, two first type wires 30 can be conducted through the first type electrode 21 and the second type electrode 22 or two second type wires 40 can be conducted through the second type electrode 22 and the third type electrode 23 to form a closed coil, and the coil structures formed by a plurality of electrodes and wires of all touch areas of the touch area 11 are consistent.

According to the touch panel, the second type electrodes 22 capable of being connected with the wires in opposite directions are added between the first type electrodes 21 and the third type electrodes 23, so that the problem that coil structures formed in specific areas, such as middle areas, of a touch area are inconsistent with coil structures formed in other areas due to the fact that all the electrodes are connected with the wires in only one direction is effectively solved, electromagnetic induction signal receiving capacity of coils formed in the touch area 11 is enhanced, consistency of electromagnetic induction signal receiving capacities of different coils is improved, linearity of receiving electromagnetic induction signals of the touch panel is improved, and accuracy of touch positioning is improved. And when the coils can also be used for transmitting electromagnetic induction signals to the outside, the electromagnetic induction signal transmitting capacity of different coils can be improved, and the consistency of signals transmitted by the touch panel is improved.

In some embodiments, as shown in fig. 3, the processing assembly 50 may be configured to turn on two electrodes of the plurality of electrodes spaced apart by P electrodes and form a coil, P being greater than or equal to 0, wherein the number of second type electrodes 22 is greater than or equal to p+1.

The processing assembly 50, when composing different coils, will space the two electrodes that compose the coils by P electrodes.

When the number of the second type electrodes 22 is greater than or equal to p+1, the first type electrode 21 closest to the second type electrode 22 may form a coil with the second type electrode 22 spaced by P electrodes, i.e., the p+1th second type electrode 22, and the third type electrode 23 closest to the first type electrode 21 is spaced by p+1th electrode from the first type electrode 21, so that the first type electrode 21 and the third type electrode 23 are not conducted and form a coil, thereby avoiding the situation that the first type electrode 21 and the third type electrode 23 are conducted to form a coil which needs to surround the touch area 11 and the coil structure is inconsistent with the coil structure of other areas, so that each coil structure formed by a plurality of electrodes and wires is consistent, enhancing the electromagnetic induction signal receiving capability of the coil formed in the touch area 11, enhancing the consistency of the electromagnetic induction signal receiving capability of different coils, enhancing the linearity of the electromagnetic induction signal received by the touch panel, and enhancing the accuracy of touch positioning.

In some embodiments, P may be any integer from 1 to 3, and exemplary P may be 2, where when the value of P is greater than the above range, the area of the coil formed by the electrode and the wire is too large, resulting in a decrease in the intensity of energy that the coil can receive, and the corresponding area of the coil and the touch area 11 is too large, which reduces the positioning accuracy of the coil on the electromagnetic induction signal, and makes it difficult to obtain a precise touch position through the coil. When the value of P is smaller than the above range, in the case where the electromagnetic induction signal source is rapidly moved, the electromagnetic induction signal source may deviate from the area range of the single coil, thereby causing loss of touch location information. The present disclosure is not limited thereto and the specific value of P may vary depending on the separation distance between the electrodes and the specific use scenario.

In some embodiments, as shown in fig. 3 and 4, 2 electrodes may be spaced between the two electrodes that make up the coil, p+1 may be 3, and the number of the 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 may turn on with the mth electrode of the spaced P electrodes and form a closed coil, and the mth electrode is the p+1th second type electrode 22, so that the electrode of the first type electrodes 21 closest to the third type electrodes 23 may turn on with the second type electrodes 22 and an effective closed coil may be formed by the first type wire 30 that turns on the nth electrode and the first type wire 30 of the mth electrode, covering the area between the nth electrode and the mth electrode.

In some embodiments, the processing assembly 50 may conduct a first type of wire 30 connected to the 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. Wherein the other electrode is the first type electrode 21 and the second type electrode 22 means that the first type electrode 21 can be conducted with the first type electrode 21 through the first type wire 30 and form a coil, and the first type electrode 21 can also be conducted with the second type electrode 22 through the first type wire 30 and form a coil.

And the processing assembly 50 may also conduct the second type of wire 40 connected to the third type of electrode 23 and the second type of wire 40 connected to another electrode, the second type of electrode 22 and the third type of electrode 23, 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 electrode 22 and the third type electrode 23 means that the third type electrode 23 can be conducted with the second type electrode 22 through the second type wire 40 and form a coil, and the third type electrode 23 can also be conducted with the third type electrode 23 through the second type wire 40 and form a coil.

By enabling the first type electrode 21 to be conducted with the first type electrode 21 with the first type wire 30 or the second type electrode 22 with the first type wire 30, and enabling the third type electrode 23 to be conducted with the second type electrode 22 with the second type wire 40 or the third type electrode 23 with the second type wire 40, the coil structure formed by conducting the electrodes and the wires is consistent, electromagnetic induction signal receiving capability of coils formed in the touch area 11 is enhanced, consistency of electromagnetic induction signal receiving capability of different coils is improved, linearity of receiving electromagnetic induction signals of the touch panel is improved, and accuracy of touch positioning is improved.

In some embodiments, the processing assembly 50 may conduct a first type of wire 30 connected to the 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.
