[0054] 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 these embodiments are given only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way.

[0055] It should be noted that although the terms "first", "second", and the like are used herein to describe different modules, steps, and data of embodiments of the present disclosure, the terms "first", "second", and the like are only used to distinguish between different modules, steps, and data, and do not indicate a specific order or importance. In fact, the terms "first", "second", and the like can be used interchangeably.

[0056] The touch panel provided by the embodiments of the present disclosure can be applied to a touch device, wherein the touch device can be any one of a capacitive touch panel, an electromagnetic touch panel, a touch display screen, a capacitive stylus, and an electromagnetic stylus.

[0057] For example, the touch device can be an electromagnetic stylus, which is a simple and fast handwriting device. The electromagnetic stylus can be used with an electromagnetic pen. The electromagnetic stylus can include an electromagnetic induction antenna panel and a control panel; the electromagnetic induction antenna panel includes a transmitting coil and a receiving coil, the transmitting coil sends electromagnetic waves to the electromagnetic pen, and the receiving coil receives a resonance signal generated by resonance of the electromagnetic waves sent by the electromagnetic pen and the transmitting coil. The control panel amplifies the received signal and performs data processing.

[0058] The transmitting coil on the electromagnetic induction antenna panel can emit an excitation signal, the resonance circuit in the electromagnetic pen can be excited by the excitation signal to provide working energy for the electromagnetic pen, after the transmitting coil stops transmitting, the resonance circuit in the electromagnetic pen will oscillate and continue to attenuate, and the receiving coil on the electromagnetic induction antenna panel will receive the oscillation signal emitted by the electromagnetic pen, thereby realizing coordinate positioning and data transmission.

[0059] The touch pen can be any one of an active capacitive pen, a passive capacitive pen, an active electromagnetic pen, and a passive electromagnetic pen.

[0060] For example, the touch pen can be a passive capacitive pen, which can be used with a capacitive touch device. The passive capacitive pen can directly interact with the capacitive layer of the screen through a conductive material (such as a metal nib), and realize touch control by using human body current or screen electric field changes.

[0061] The passive capacitive pen can also be provided with a resonance circuit, and can be used with a capacitive touch device provided with an excitation coil and a receiving coil. The excitation coil of the touch device can emit an excitation signal, and the resonance circuit in the passive capacitive pen can be excited by the excitation signal to provide working energy for the capacitive pen, so that the passive capacitive pen can emit a wireless signal, and the touch device receives the signal feedback by the passive capacitive pen through the coil and the capacitive sensor and confirms the coordinate, pressure, key, and other information of the passive capacitive pen.

[0062] In the related art, in order to make the stylus excitation coil, the transmitting coil and the capacitive touch sensor of the touch device be implemented through the same circuit structure, both ends of the conductive component are connected to the control circuit through wires, which increases the wiring area required by the touch panel and increases the complexity of the circuit. When switching between transmitting excitation energy to the stylus, receiving the electrical signal fed back by the stylus, identifying the electromagnetic stylus touch information and identifying the finger or capacitive stylus touch information, an additional set of switches is needed to control the on-off of the ends of the conductive component. When transmitting excitation energy to the stylus, receiving the electrical signal fed back by the stylus and identifying the electromagnetic stylus touch information, the switches control different conductive components to be connected and form a coil. When identifying the finger or capacitive stylus touch information, the switches control different conductive components to be disconnected to form a capacitive touch sensor structure. The additional switches are easy to introduce noise into the circuit, thereby reducing the recognition accuracy of the touch information.

[0063] Figure 1 is a structural schematic diagram of a touch panel according to an embodiment of the present disclosure.

[0064] In some embodiments, as shown in Figure 1 The touch panel can include a substrate 60, a first conductive component 10, a plurality of second conductive components 20 and a plurality of third conductive components 30. The substrate 60 can be used to provide mounting positions for other components of the touch panel, and can provide wiring space for the touch panel. The first conductive component 10, the second conductive component 20 and the third conductive component 30 can be components with conductivity.

[0065] The first conductive component 10 can be disposed on the substrate 60 and extend along a first direction, and the plurality of second conductive components 20 can be disposed on the substrate 60 and extend along a second direction, wherein the first direction and the second direction are two different directions. For example, the first direction and the second direction can be two perpendicular directions.

[0066] The third conductive component 30 can be disposed on the substrate 60, and the third conductive component 30 can include a first end 31 and a second end 32. The first end 31 can be connected to the first conductive component 10, and the second end 32 can be connected to one end of the second conductive component 20, so that the second conductive component 20 can be connected to the first conductive component 10 through the third conductive component 30. The resistance value of the third conductive component 30 is greater than a resistance threshold value.

[0067] The resistance threshold value can satisfy that any two of the plurality of second conductive components 20 support electrical connection with the first conductive component 10 through the third conductive component 30 in the on state, and the two second conductive components 20, the two third conductive components 30 and the first conductive component 10 can form a coil, which can be used to emit an excitation signal or receive a first electrical signal. The excitation signal can be used to provide energy for a stylus used in cooperation with the touch device. The touch device can transmit energy to the stylus, including passive electromagnetic pens and passive capacitive pens, through the coil. The first electrical signal can be an electrical signal fed back by the stylus used in cooperation with the touch device. The touch device can emit or receive signals to the stylus through the coil, which needs to interact with the signal. By electrically connecting one end of the two second conductive components 20 through the third conductive component 30 and the first conductive component 10, the two second conductive components 20, the two third conductive components 30 and the first conductive component 10 form a complete current loop and form a coil structure, thereby emitting an excitation signal to the stylus or receiving a first electrical signal fed back by the touch device, realizing energy transmission and signal interaction of the stylus.

[0068] The resistance threshold value can also satisfy that any two of the plurality of second conductive components 20 support receiving the same second electrical signal in the on state, and form a differential signal group for sensing the touch operation of a finger or a capacitive pen. The second electrical signal can be an alternating current signal. For example, when a finger approaches one of the two conductive components, since the finger is a conductor, it is equivalent to forming a capacitor between the second conductive component 20 approached by the finger and the ground. The current of the second conductive component 20 approached by the finger is shunted to the ground, thereby causing the second conductive component 20 approached by the finger to attenuate the electrical signal, and thereby generating a voltage difference between the electrical signal of the other second conductive component 20 in the on state. By detecting the corresponding relationship between the voltage difference and the second conductive component 20, the touch position and trajectory of the finger can be determined, realizing the touch detection function of the finger.

[0069] The resistance value of the third conductive component 30 is greater than the resistance threshold value, so the third conductive component 30 can inhibit the flow of current between the two second conductive components 20, so that a sufficient voltage difference can be maintained between the two second conductive components 20 for capacitive touch detection.

[0070] The smaller the resistance value of the third conductive component 30, the smaller the total resistance of the coil formed by the conductive component, the lower the current loss rate in the coil, the higher the excitation efficiency and signal transceiving efficiency of the coil, and the stronger the electromagnetic touch detection performance. The larger the resistance value of the third conductive component 30, the more the current flow between the two second conductive components 20 can be inhibited, so that a larger voltage difference between the two second conductive components 20 can be maintained when a finger or a capacitive pen approaches, to improve the detection sensitivity and other detection performances of capacitive touch detection. That is, the excitation efficiency and reception efficiency of the coil formed in the touch panel change inversely with the resistance value of the third conductive component 30. The voltage difference between the two second conductive components 20 of the differential signal group changes in direct proportion to the resistance value of the third conductive component 30.

[0071] According to the above principle, by adjusting the resistance value of the third conductive component 30 within a moderate resistance range, the third conductive component 30 can not only ensure the accuracy of electromagnetic touch detection when the second conductive components 20 on the touch panel are connected to form a coil for electromagnetic touch detection, but also inhibit the current flow between the differential signal groups to maintain a sufficient voltage difference for capacitive touch detection.

[0072] The first conductive component 10 and the second conductive component 20 are connected by the third conductive component 30 with a larger resistance value, so that when the second conductive component 20 forms a coil, the third conductive component 30 and the first conductive component 10 can form a coil to transmit energy to the stylus and exchange signals with the stylus, such as touch positioning of the electromagnetic stylus, and when the second conductive component 20 forms a differential signal group, the third conductive component 30 with a larger resistance value can inhibit the current flow between the two second conductive components 20, so that a voltage difference can be formed between the two second conductive components 20 when a finger or a capacitive pen approaches, to detect finger or capacitive pen touch operation. With a relatively simple structure, energy transmission and signal exchange with the stylus are realized, and electromagnetic touch detection and capacitive touch detection of the stylus such as the electromagnetic stylus are integrated, avoiding the introduction of noise to the touch panel by additional switching process, and improving the touch recognition accuracy of the touch panel. Moreover, the plurality of second conductive components 20 extending in the second direction can be connected to each other by the third conductive component 30 and the first conductive component 10 extending in the first direction to form a coil, and different coils can be formed by switching different conductive components, avoiding the dense arrangement of multiple coils which leads to crossing of the wires and the need for additional punching of the wires, thereby reducing the installation cost of the touch panel.

[0073] In some embodiments, the resistance threshold value can be greater than the resistance value of the first conductive component 10, and therefore the resistance value of the third conductive component 30 can be greater than the resistance value of the first conductive component 10.

[0074] In the coil structure of the touch panel, the first conductive component 10 is a main structure connecting the ends of two different second conductive components 20, and the first conductive component 10 is configured to have a small resistance value, which can reduce the total resistance of the coil structure of the touch panel, thereby improving the signal transmission performance of the coil formed by the second conductive component 20, the third conductive component 30, and the first conductive component 10.

[0075] The third conductive component 30 is configured to have a large resistance value, which is conducive to inhibiting the current flow between the second conductive components 20 forming the differential signal group, so as to maintain a sufficient voltage difference for capacitive touch detection.

[0076] In some embodiments, the plurality of second conductive components 20 forming the differential signal group can include two adjacent second conductive components 20. The spacing of the second conductive components 20 forming the differential signal group determines the theoretical minimum resolution of touch position detection. The smaller the electrode spacing, the greater the signal change caused by the movement of the touch point of the finger or the capacitive pen between the two electrodes, and the more accurate the touch position calculation. Therefore, by forming a differential signal group with two adjacent second conductive components 20, the positioning accuracy of the finger or capacitive pen touch signal can be improved.

[0077] Figure 2 is a structural diagram of a touch panel according to an embodiment of the present disclosure.

[0078] In some embodiments, as shown in Figure 2 , the angle between the connection direction of the first end and the second end and the first direction is less than 90 degrees. By making the connection direction of the first end and the second end non-perpendicular to the first direction, compared with the connection mode in which the connection direction of the first end and the second end is perpendicular to the first direction, the third conductive component 30 can be connected to the first conductive component 10 at an angle, increasing the straight-line distance between the first end and the second end, so that the third conductive component 30 can obtain more wiring space, so as to increase the total length and total resistance of the third conductive component 30, thereby enabling the third conductive component 30 to better inhibit the current flow between the second conductive components 20 forming the differential signal group, so as to maintain a sufficient voltage difference for capacitive touch detection.

[0079] In some embodiments, as shown in Figure 1 and Figure 2 , the width of the third conductive component 30 is smaller than the width of the first conductive component 10. Under the same conditions, the longer the length of the conductive component, the greater the resistance value. By reducing the width of the third conductive component 30, the third conductive component 30 can have a larger resistance in a limited wiring space, which can better inhibit the current flow between the second conductive components 20 forming the differential signal group, so as to better maintain a sufficient voltage difference for capacitive touch detection of the finger or the capacitive pen.

[0080] The first conductive component 10 and the second conductive component 20 are main structures of the coil in the touch panel. Configuring the resistance values of the first conductive component 10 and the second conductive component 20 to be small can reduce the total resistance of the coil in the touch panel, thereby improving the signal transmission performance of the coil formed by the second conductive component 20, the third conductive component 30 and the first conductive component 10.

[0081] In some embodiments, as shown in FIG. 1, the width of the third conductive component 30 can be less than the width of the second conductive component 20, so that the resistance value of the third conductive component 30 is greater. However, the present disclosure is not limited thereto. According to the resistance value requirement of the second conductive component 20, the width of the second conductive component 20 can also be greater than the width of the third conductive component 30. Figure 1 Figure 2 As shown in FIG. 1, the third conductive component 30 can include one or more of a straight line portion, an arcuate portion and a zigzag portion. That is, the third conductive component 30 can include one of a straight line portion, an arcuate portion and a zigzag portion, so that the third conductive component 30 can be in a straight line shape, an arcuate shape or a zigzag shape, or a combination of a straight line portion, an arcuate portion and a zigzag portion. For example, the third conductive component 30 can include a straight line portion and a zigzag portion connected end to end.

[0082] Figure 3 FIG. 1 is a structural schematic diagram of a touch panel according to an embodiment of the present disclosure.

[0083] In some embodiments, as shown in FIG. 1, the width of the third conductive component 30 can be less than the width of the second conductive component 20, so that the resistance value of the third conductive component 30 is greater. However, the present disclosure is not limited thereto. According to the resistance value requirement of the second conductive component 20, the width of the second conductive component 20 can also be greater than the width of the third conductive component 30. Figures 1 to 3

[0084] The straight line portion can be a straight line structure. The production process of the straight line portion is relatively simple, and the cost is relatively low.

[0085] The arcuate portion can be an arcuate structure. In the case that the positions of the first end 31 and the second end 32 are fixed, the arcuate portion can have a longer wire length than the straight line portion, so that the third conductive component 30 can have a greater resistance in a limited wire space, and can better inhibit the current flow between the second conductive components 20 forming the differential signal group, so as to better maintain a sufficient voltage difference for capacitive touch detection.

[0086] The zigzag portion can be a structure formed by connecting a plurality of straight line structures with different extension directions end to end. The production process of the zigzag portion is relatively simple, and in the case that the positions of the first end 31 and the second end 32 are fixed, the zigzag portion can have a longer wire length than the straight line portion, so that the third conductive component 30 can have a greater resistance in a limited wire space, and can better inhibit the current flow between the second conductive components 20 forming the differential signal group, so as to better maintain a sufficient voltage difference for capacitive touch detection.

[0087] ​​In some embodiments, the resistance values ​​of the plurality of third conductive components 30 are equal or the resistance difference of the plurality of third conductive components 30 is within a preset difference range. This can improve the parameter consistency of each coil and each differential signal group formed by the conductive components, reduce parameter variables in the circuit calculation process, and help reduce the difficulty of circuit design and algorithm design.

[0088] Regarding the preset difference range, when the resistance values ​​of the third conductive components 30 are basically equal, the production process or design requirements allow the resistance values ​​of the third conductive components 30 to have a certain difference, so that the parameters of each coil and each differential signal group are basically consistent. The range of this difference is the preset difference range.

[0089] In some embodiments, such as Figures 1 to 3 As shown, the second conductive component 20 may include a third end 21 and a fourth end 22 opposite to each other. The third end 21 is connected to the second end 32. The touch panel may include a control unit 5, which can be used to control the conduction relationship and conduction state of the conductive components in the touch panel. The control unit 5 may include: multiple input terminals 50, output terminals 53, and a control circuit 40.

[0090] Multiple input terminals 50 can be connected to the fourth terminal 22 for inputting a second electrical signal to the second conductive component 20 or a third electrical signal for generating an excitation signal. An output terminal 53 can be connected to the fourth terminal 22 for connecting the fourth terminal 22 to a fixed voltage level or grounding. A control circuit 40 can be connected to the multiple input terminals 50, the output terminal 53, and the fourth terminal 22 respectively. The control circuit 40 is used to control the conduction state between the multiple input terminals 50 and the output terminal 53 and the fourth terminal 22. For example, the multiple input terminals 50 may include a first input terminal 51 and a second input terminal 52.

[0091] The control circuit 40 can control one of the multiple input terminals 50 to input a third electrical signal to the Nth second conductive component 20. The control circuit 40 controls the output terminal 53 to connect the fourth terminal 22 of the Mth second conductive component 20 to a fixed level or ground it, so that the Nth second conductive component 20, the third conductive component 30 connected to the Nth second conductive component 20, the first conductive component 10, the third conductive component 30 connected to the Mth second conductive component 20, and the Mth second conductive component 20 form a coil, and the coil emits an excitation signal according to the third electrical signal.

[0092] The control circuit 40 can control two of the multiple input terminals 50 to input the same second electrical signal to the Pth second conductive component 20 and the Qth second conductive component 20 respectively, so that the Pth second conductive component 20 and the Qth second conductive component 20 form a differential signal group, and recognize the touch information of the finger or capacitive pen according to the changes in the electrical signals in the Pth second conductive component 20 and the Qth second conductive component 20.

[0093] N, M, P, and Q are positive integers. For example, N and M can be positive integers with a difference of 2 or 3, so that the coil formed by the Nth second conductive component 20 and the Mth second conductive component 20 can have a larger coverage area. P and Q can be positive integers with a difference of 1, so that the Pth second conductive component 20 and the Qth second conductive component 20 are two adjacent second conductive components 20, thereby improving the positioning accuracy of finger or capacitive pen touch signals.

[0094] By connecting the first conductive component 10 and the second conductive component 20 through the third conductive component 30 with a larger resistance value, and controlling the conduction relationship of the input terminal 50, the output terminal 53 and the second conductive component 20 through the control circuit 40, the first conductive component 10, the second conductive component 20 and the third conductive component 30 can be controlled to form a coil or a differential signal group by controlling the second conductive component 20 to conduct with different input terminals 50 or output terminals 53. The energy transmission and signal interaction of the stylus are realized with a relatively simple structure, as well as the integration of electromagnetic touch detection and capacitive touch detection. This avoids the introduction of noise into the touch panel by the additional switching process and improves the touch recognition accuracy of the touch panel.

[0095] In some embodiments, such as Figures 1 to 3 As shown, the width L1 of the multiple second conductive components 20 is the same. By making the width L1 of the multiple second conductive components 20 equal, the resistance values ​​of two different second conductive components 20 are the same. This allows the same second electrical signal fed into different second conductive components 20 to generate the same current and voltage, so that the voltage difference of the differential signal group remains zero when the finger or capacitive stylus is not touched. Furthermore, this also ensures that the performance parameters of the multiple coils formed by the second conductive components 20 are consistent, thereby improving the consistency of the multiple coils, reducing parameter variables in the circuit calculation process, and helping to reduce the difficulty of circuit design and algorithm design.

[0096] In some embodiments, the width L1 of the second conductive component 20 located at the edge of the substrate 60 can be smaller than the width L1 of the second conductive component 20 located at the middle of the substrate 60, so as to reduce the space occupied by the second conductive component 20 located at the edge of the substrate 60, and enable the second conductive component 20 located at the edge of the substrate 60 to form both the coil and the differential signal group with other second conductive components 20, so as to detect the touch at the edge of the substrate 60, and form a narrower edge structure, thereby improving the adaptability of the touch panel to the narrow frame device.

[0097] In some embodiments, the width L1 of the second conductive component 20 can be 4mm to 7mm. By configuring the width L1 of the second conductive component 20 within the above range, the second conductive component 20 can have a larger width, the resistance of the second conductive component 20 can be reduced, and the total resistance of the coil formed by the second conductive component 20 can be reduced, thereby improving the signal transmission efficiency of the coil.

[0098] In some embodiments, as shown in FIG. 2, the center of each adjacent second conductive component 20 can have a second interval L2, and the second interval L2 is within a preset interval threshold range. Figures 1 to 3 When the second interval L2 is too large, the area of the excitation coil formed by the second conductive component 20 can be too large, the coil energy can be dispersed, the excitation efficiency can be reduced, and the positioning accuracy of the differential signal group to the touch signal of the finger or the capacitive pen can also be reduced. When the second interval L2 is too small, the area covered by the excitation coil formed by the second conductive component 20 can be too small, and more second conductive components 20 need to be arranged, thereby increasing the setting cost of the touch panel.

[0099] In some embodiments, as shown in FIG. 2, each adjacent second conductive component 20 has a first interval L3, and the plurality of first intervals L3 are the same. This can improve the parameter consistency of each coil and each differential signal group formed by the second conductive component 20, can avoid measuring and calculating the interval between different second conductive components 20 one by one, can reduce the parameter variables in the circuit calculation process, and is beneficial to reducing the difficulty of circuit design and algorithm design. Figures 1 to 3 In some embodiments, as shown in FIG. 2, the first interval L3 is within a first interval threshold range. When the first interval L3 is too large, the area of the excitation coil formed by the second conductive component 20 can be too large, the coil energy can be dispersed, the excitation efficiency can be reduced, and the positioning accuracy of the differential signal group to the touch signal of the finger or the capacitive pen can also be reduced. When the first interval L3 is too small, the area covered by the excitation coil formed by the second conductive component 20 can be too small, and more second conductive components 20 need to be arranged, thereby increasing the setting cost of the touch panel.

[0100] Figures 1 to 3 In some embodiments, as shown in FIG. 2, the first interval L3 is within a first interval threshold range. When the first interval L3 is too large, the area of the excitation coil formed by the second conductive component 20 can be too large, the coil energy can be dispersed, the excitation efficiency can be reduced, and the positioning accuracy of the differential signal group to the touch signal of the finger or the capacitive pen can also be reduced. When the first interval L3 is too small, the area covered by the excitation coil formed by the second conductive component 20 can be too small, and more second conductive components 20 need to be arranged, thereby increasing the setting cost of the touch panel. ​

[0101] In some embodiments, the first interval threshold range can be 5um to 1mm. Configuring the first interval L3 within the above range can keep the coil formed by the second conductive components 20 with sufficient coverage area while maintaining sufficient excitation efficiency.

[0102] In some embodiments, as shown in FIG. 1, the substrate 60 can include a touch area 61, and the plurality of second conductive components 20 can be disposed within the touch area 61. The touch area 61 can be an area in the touch panel capable of touch detection, and can also be an area for image display. The plurality of second conductive components 20 can be metal mesh conductive components and / or transparent conductive components. Figures 1 to 3 By configuring the second conductive components 20 as metal mesh conductive components and / or transparent conductive components, the second conductive components 20 can have good light transmittance, reducing interference with the display image passing through the touch panel. And because the second conductive components have good light transmittance, the resistance can be reduced by increasing the width of the second conductive components without affecting the overall light transmittance of the second conductive components 20, thereby reducing the resistance of the coil in the touch panel and improving the excitation efficiency of the coil.

[0103] In some embodiments, as shown in FIG. 1, the first conductive component 10 and the plurality of third conductive components 30 can be disposed outside the touch area 61, and the first conductive component 10 and the plurality of third conductive components 30 are solid metal conductive components. At the same width, solid metal conductive components have smaller resistance, so configuring the first conductive component 10 and the third conductive components 30 as solid metal conductive components can make the first conductive component 10 and the third conductive components 30 have smaller width while maintaining lower resistance, so as to reduce the wiring space occupied by the first conductive component 10 and the third conductive components 30 and improve the adaptability of the touch panel to narrow frame devices.

[0104] Figures 1 to 3 In some embodiments, the substrate 60 is a transparent material, so that the substrate 60 has good light transmittance, and the display image can be normally displayed through the substrate 60, reducing the interference of the touch panel with the display image passing through the touch panel. For example, the substrate 60 can be a transparent film, a transparent glass, or other light-transmitting components capable of disposing conductive components.

[0105] In some embodiments, the resistance value of the third conductive component 30 is 10 ohms to 1000 ohms.

[0106] In some embodiments, the resistance value of the third conductive component 30 is 10 ohms to 1000 ohms.

[0107] ​The smaller the resistance value of the third conductive component 30, the smaller the total resistance of the coil formed by the conductive component, the lower the current loss rate in the coil, the higher the excitation efficiency and signal receiving efficiency of the coil, and the stronger the electromagnetic touch detection performance. The larger the resistance value of the third conductive component 30, the more the current flow between the two second conductive components 20 can be inhibited, so that a larger voltage difference between the two second conductive components 20 can be maintained when a finger or a capacitive pen approaches, to improve the detection sensitivity and other detection performance of capacitive touch. That is, the excitation efficiency and receiving efficiency of the coil formed in the touch panel change inversely with the resistance value of the third conductive component 30. The voltage difference between the two second conductive components 20 of the differential signal group changes in direct proportion to the resistance value of the third conductive component 30.

[0108] According to the above principle, the energy excitation efficiency of the coil on the stylus, the signal interaction performance with the stylus, the positioning performance on the electromagnetic pen, and the touch positioning performance on the finger or capacitive pen can be targetedly improved by adjusting the resistance value of the third conductive component 30. For example, the resistance of the third conductive component 30 can be configured to 100 ohms, which can ensure the excitation efficiency and receiving efficiency of the coil formed in the touch panel, and improve the touch positioning performance of the touch panel on the finger or capacitive pen.

[0109] Figure 4 is a structural schematic diagram of a touch panel according to another embodiment of the present disclosure.

[0110] Based on the same concept, the present disclosure also provides a touch device, such as Figure 4 As shown, the touch device can include a first touch panel and a second touch panel. The first touch panel and the second touch panel can share the same substrate 60 as the framework structure, and the conductive components are arranged on the same substrate 60, thereby reducing the number of substrates 60, reducing the installation space of the touch panel, and being conducive to reducing the overall thickness of the touch device. The substrate 60 includes opposite first and second surfaces, and the first conductive component 10, the second conductive component 20, and the third conductive component 30 of the first touch panel can be located on the first surface, and the first conductive component 10, the second conductive component 20, and the third conductive component 30 of the second touch panel can be located on the second surface. However, the present disclosure is not limited thereto, and the conductive components of the first touch panel and the conductive components of the second touch panel can also be arranged on two different substrates 60. Among them, the first direction and the second direction are two directions intersecting with each other, and for example, the first direction and the second direction can be two directions perpendicular to each other.

[0111] The plurality of second conductive components 20 of the first touch panel can be arranged along the first direction, so that the plurality of coils and the plurality of differential signal groups formed by the first touch panel are arranged along the first direction. By sequentially conducting the plurality of coils arranged along the first direction, a relationship curve between electromagnetic induction signal strength in the first direction and touch area coordinates can be obtained. By sequentially conducting the plurality of differential signal groups arranged along the first direction, a relationship curve between capacitive touch signal strength in the first direction and touch area coordinates can be obtained. According to the relationship curve, the first touch panel can obtain touch coordinates in the first direction of electromagnetic touch and capacitive touch.

[0112] The plurality of second conductive components 20 of the second touch panel can be arranged along the second direction, so that the plurality of coils and the plurality of differential signal groups formed by the second touch panel are arranged along the second direction. By sequentially conducting the plurality of coils arranged along the second direction, a relationship curve between electromagnetic induction signal strength in the second direction and touch area coordinates can be obtained. By sequentially conducting the plurality of differential signal groups arranged along the second direction, a relationship curve between capacitive touch signal strength in the second direction and touch area coordinates can be obtained. According to the relationship curve, the second touch panel can obtain touch coordinates in the second direction of electromagnetic touch and capacitive touch.

[0113] The first touch panel for obtaining touch coordinates in the first direction and the second touch panel for obtaining touch coordinates in the second direction both realize integration of electromagnetic touch detection and capacitive touch detection through a simpler structure, avoid introducing noise to the touch panel through an additional switching process, improve touch recognition accuracy of the touch panel, improve use experience of the touch device, and reduce production cost of the touch device. In addition, by providing two first conductive components 10 connected to the end of the second conductive component 20, the related wire layout is reduced, the required layout space of the touch panel is reduced, which is helpful to adapt to the narrow frame setting of the touch device.

[0114] Figure 5 is a structural schematic diagram of a touch panel according to another embodiment of the present disclosure.

[0115] Based on the same concept, the present disclosure also provides a touch device, as shown in Figure 5 The touch device can include a first touch panel and a third touch panel.

[0116] The first touch panel can include a substrate 60, a first conductive component 10, a plurality of second conductive components 20, a plurality of third conductive components 30, and a control circuit 40. The substrate 60 includes opposite first and second surfaces, and the first, second, and third conductive components 10, 20, and 30 of the first touch panel can be located on the first surface.

[0117] The third touch panel can include a plurality of fourth conductive components 70 arranged on the second surface, and both ends of each fourth conductive component 70 of the plurality of fourth conductive components 70 are connected to the control circuit 40 through wires. The control circuit 40 can control whether any one end of the fourth conductive component 70 is conductive, so that the fourth conductive component 70 can form a coil or a differential signal group. For example, by making the ends of two fourth conductive components 70 conductive, the two fourth conductive components 70 can be conductive to each other and form a coil. By making one end of the two fourth conductive components conductive, the other end of the two fourth conductive components can be disconnected, so that the two fourth conductive components 70 form a differential signal group.

[0118] The plurality of second conductive components can be arranged along the first direction, so that the plurality of coils and the plurality of differential signal groups formed by the first touch panel are arranged along the first direction. By sequentially making the plurality of coils arranged along the first direction conductive, a relationship curve between electromagnetic induction signal strength in the first direction and touch area coordinates can be obtained. By sequentially making the plurality of differential signal groups arranged along the first direction conductive, a relationship curve between capacitive touch signal strength in the first direction and touch area coordinates can be obtained. According to the relationship curves, the first touch panel can obtain touch coordinates in the first direction of electromagnetic touch and capacitive touch.

[0119] The plurality of fourth conductive components can be arranged along the second direction, so that the plurality of coils and the plurality of differential signal groups formed by the third touch panel are arranged along the second direction. By sequentially making the plurality of coils arranged along the second direction conductive, a relationship curve between electromagnetic induction signal strength in the second direction and touch area coordinates can be obtained. By sequentially making the plurality of differential signal groups arranged along the second direction conductive, a relationship curve between capacitive touch signal strength in the second direction and touch area coordinates can be obtained. According to the relationship curves, the third touch panel can obtain touch coordinates in the second direction of electromagnetic touch and capacitive touch.

[0120] Based on the same principle, the plurality of second conductive components can also be arranged along the second direction to support the first touch panel to obtain touch coordinates in the second direction of electromagnetic touch and capacitive touch. The plurality of fourth conductive components can be arranged along the first direction to support the third touch panel to obtain touch coordinates in the first direction of electromagnetic touch and capacitive touch. In the design process of the touch device, the detection direction of the first touch detection panel and the detection direction of the second touch detection panel can be allocated according to the touch requirements of the touch device in different directions.

[0121] The first touch panel realizes energy transmission and signal interaction of the stylus, integration of electromagnetic touch detection and capacitive touch detection through a relatively simple structure, avoids noise introduced to the touch panel by an additional switching process, improves touch recognition accuracy of the touch panel, and further reduces relevant wire routing by arranging the first conductive component 10 to connect the end of the second conductive component 20, thereby reducing the required routing space of the touch panel and helping to adapt to the narrow frame setting of the touch device. The third touch panel has better recognition performance in the electromagnetic detection mode and the capacitive detection mode while realizing energy transmission and signal interaction of the stylus, integration of electromagnetic touch detection and capacitive touch detection. After the touch detection mode is switched by the control circuit 40, the coil and the differential signal group formed by the third touch panel have good touch detection performance.

[0122] Based on the same concept, the embodiments of the present disclosure also provide a touch device. The touch device can include a touch panel. The touch panel can form a coil to transmit energy of the touch device to a stylus through an excitation signal or receive a first electric signal fed back by the stylus, so that the touch device provides energy to the stylus and interacts with the stylus, and can obtain positioning information of the stylus such as an electromagnetic stylus. The touch panel can also form a differential signal group, so that the touch panel can position a finger or a capacitive stylus and enable a user to control the touch device through the finger or the capacitive stylus.

[0123] The present disclosure realizes energy transmission and signal interaction of the stylus, integration of electromagnetic touch detection and capacitive touch detection through a relatively simple structure, avoids noise introduced to the touch panel by an additional switching process, improves touch recognition accuracy of the touch panel, improves user experience of the touch device, and reduces production cost of the touch device. In addition, the plurality of second conductive components 20 extending along the second direction can be connected to each other through the third conductive component 30 and the first conductive component 10 extending along the first direction to form a coil, and different coils can be formed by switching different conductive components to be turned on, thereby reducing the setting cost of the touch panel and the production cost of the touch device.

[0124] In some embodiments, the touch device can make the touch panel cyclically switch between the electromagnetic touch detection mode and the capacitive touch detection mode in a default state. When the touch device can detect the stylus, the touch device can maintain the touch panel in the electromagnetic touch detection mode or the capacitive touch detection mode to keep recognizing the stylus.
