[0003] The stylus usually includes a touch component, such as the tip of the stylus, and the writing operation is performed by the contact between the touch component and the touch surface. However, after the touch component is used for a period of time, the part of the touch component in contact with the touch surface is worn out, and the internal metal structure will scratch the touch surface of the electronic device.

[0008] The touch component, the touch pen and the touch pen system provided by the embodiments of the present application can expose the conductive layer first and make the conductive layer be worn out after the touch body is worn out by arranging the conductive layer between the conductor and the contact surface and insulating and spacing the conductive layer from the conductor and the contact surface.

[0031] Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some of these specific details. The description of the embodiments is merely to provide a better understanding of the present application by showing examples of the present application. In the drawings and the following description, at least part of the well-known structures and techniques are not shown in order to avoid unnecessary obscuring of the present application; and, for clarity, the size of some structures can be exaggerated. In addition, the features, structures or characteristics described below can be combined in any suitable manner in one or more embodiments.
[0032] Furthermore, for the sake of understanding and ease of description, the dimensions and thicknesses of each configuration shown in the figures are arbitrarily illustrated, but the concept of this application is not limited thereto. In the figures, the thicknesses of layers, films, panels, and regions, etc., are enlarged for clarity. In the figures, the thicknesses of some layers and regions are enlarged for better understanding and ease of description.
[0033] It is understandable that when an element such as a layer, film, region, or substrate is described as being "on" another element, the element may be directly on that other element, or there may be intermediate elements present. In contrast, when an element is described as being "directly on" another element, there are no intermediate elements present. Furthermore, throughout the specification, the phrase "on" the target element indicates that it is positioned above or below the target element and does not necessarily indicate that it is positioned "on the upper side" based on the direction of gravity.
[0034] Furthermore, unless explicitly stated otherwise, the word "including" will be understood to include the stated elements but not exclude any other elements.
[0035] When a stylus is used for writing or other operations on the touch surface of an electronic device, the stylus's touch components, such as the tip, rub against the touch surface. As the stylus is used over time, these components gradually wear down, exposing the internal metal. If the user continues to use the worn stylus without noticing this wear and the exposed metal, the pen will continue to rub against the touch surface during writing, thus increasing the risk of scratching the touch surface.
[0036] In view of this, this application provides a touch component, a stylus using the touch component, and a stylus system including the stylus.
[0037] like Figure 1 As shown, the touch component 100 provided according to an embodiment of this application includes a touch body 110, a conductor 120, and a conductive layer 130. The touch body 110 has a receiving cavity 110a and a contact surface 110b, with the contact surface 110b exposed on at least a portion of the surface of the touch body 110. The conductor 120 is received within the receiving cavity 110a, and the conductive layer 130 is disposed on the touch body 110. The conductive layer 130 is located between the conductor 120 and the contact surface 110b, and is insulated from and spaced apart from the conductor 120 and the contact surface 110b. The conductive layer 130 has a through hole, and at least a portion of the projection of the conductor 120 onto the contact surface 110b covers the through hole.
[0038] The touch component 100 may be the tip of a stylus or other component that needs to come into contact with the touch surface of an electronic device.
[0039] The touch body 110 can be made of an insulating material. The contact surface 110b of the touch body 110 can be the entire area of the touch body 110 exposed to the outside, or the contact surface 110b can be part of the area of the touch body 110 exposed to the outside. The contact surface 110b can be used to contact the touch surface of the electronic device to achieve the writing function of the electronic device.
[0040] The conductive body 120 is accommodated in the accommodating cavity 110a of the touch body 110, and the touch body 110 can provide certain protection for the conductive body 120, and can reduce the risk of the conductive body 120 accidentally injuring the human body or the touch surface.
[0041] The conductive body 120 can include metal or gas conductive materials. When the contact surface of the touch body 110 contacts the touch surface of the electronic device, the conductive body 120 can generate an electrical signal with the corresponding area on the touch surface. According to the position of the conductive body 120 relative to the touch surface of the electronic device, the corresponding position of the touch surface displays text, patterns or graphics to complete the writing work.
[0042] The conductive layer 130 is located between the conductive body 120 and the contact surface 110b, and is insulated and spaced apart from the conductive body 120 and the contact surface 110b. The conductive layer 130 is spaced apart from the conductive body 120 and the contact surface 110b. The conductive layer 130 can be a flat layer; or the conductive layer 130 can be an arc-shaped layer. For example, the conductive layer 130 can be parallel to the contact surface 110b.
[0043] The conductive layer 130 has a through hole. The conductive layer 130 can be in the form of a sheet and have a through hole, or the conductive layer 130 can be in the form of a wire or a strip and surround the through hole.
[0044] The through hole can be circular, square or irregular in shape, which is not limited here and can be selected as needed.
[0045] The touch component 100 can include one conductive layer 130; or the touch component 100 includes multiple conductive layers 130. In the embodiment in which the touch component 100 includes one conductive layer 130, the conductive layer 130 can be arranged close to the conductive body 120 to increase the depth of wear of the touch body 110, thereby increasing the service life of the touch component. In the embodiment in which the touch component 100 includes multiple conductive layers 130, the conductive layer 130 closest to the conductive body 120 can also be arranged close to the conductive body 120 to increase the depth of wear of the touch body 110.
[0046] The projection of the conductive layer 130 on the contact surface 110b is the projection of each region of the conductive layer 130 along the normal of each position of the contact surface 110b, and at least part of the projection of the conductive body 120 on the contact surface 110b covers the through hole. Therefore, at least part of the conductive body 120 can transmit electrical signals through the through hole and the touch surface of the electronic device, so as to reduce the risk that the conductive layer 130 shields the conductive body 120 and causes the touch component 100 to malfunction.
[0047] Since the conductive layer 130 is located between the conductive body 120 and the contact surface 110b, as the touch component 100 is used for a long time, the touch body 110 is gradually worn out, and the conductive layer 130 is exposed and worn out before the conductive body 120. As the conductive layer 130 is worn out, the circuit in which the conductive layer 130 is located is disconnected or the resistance value of the conductive layer 130 changes. Therefore, in the case that the touch component 100 is applied to a stylus, the wear position or wear amount of the conductive layer 130 can be recognized by a related module inside the stylus according to the change of the resistance value of the conductive layer 130, so as to determine the distance between the conductive body 120 and the contact surface 110b. When the resistance value of the conductive layer 130 reaches a predetermined threshold value or the circuit in which the conductive layer 130 is located is disconnected, it is determined that if the touch component 100 continues to be used, the conductive body 120 will be exposed and directly contact the touch surface of the electronic device. Therefore, the operator can adjust the holding posture of the stylus or replace the stylus in time when the resistance value of the conductive layer 130 reaches the predetermined threshold value or the circuit in which the conductive layer 130 is located is disconnected, so as to reduce the risk that the conductive body 120 is exposed to the outside of the touch component 100 and scratches the touch surface of the electronic device. For example, the stylus can remind the operator by voice or prompt sound, or display a pattern on a display device connected to the stylus to remind the operator of the wear information of the touch component 100.
[0048] It can be understood that the predetermined threshold value of the resistance value of the conductive layer 130 can be determined by experiments after the touch component 100 is prepared.
[0049] The touch component 100 can include one conductive layer 130 or multiple conductive layers 130 which are insulated from each other and connected in parallel. From the direction in which the conductive body 120 points to the contact surface 110b, the multiple conductive layers 130 can be arranged at intervals, so that the multiple conductive layers 130 correspond to different wear degrees of the touch body 110 respectively, and the operator can determine the wear degree of the touch body 110. Of course, the multiple conductive layers 130 can also be connected in parallel, and the multiple conductive layers 130 can correspond to different positions of the contact surface 110b respectively, so as to determine the wear of different positions of the touch body 110 by the conductive layer 130.
[0050] The conductive layer 130 can cover the entire area of the conductor 120 facing the contact surface 110b. That is, any direction from the contact surface 110b to the conductor 120 must pass through the conductive layer 130. Thus, as the touch body 110 wears down, the conductive layer 130 is exposed and worn down before the conductor 120. Wear of the touch body 110 at any position will expose the internal conductive layer 130, and the degree of wear of the touch body 110 can be judged by the conductive layer 130.
[0051] Alternatively, the conductive layer 130 can cover a portion of the conductor 120 facing the contact surface 110b, meaning that a portion of the direction from the contact surface 110b to the conductor 120 needs to pass through the conductive layer 130. Thus, as the contact surface 110b corresponding to the conductive layer 130 wears down, the conductive layer 130 is gradually exposed and wears down. Therefore, the degree of wear on the touch body 110 corresponding to the threshold can be determined through the conductive layer 130.
[0052] The touch component 100 provided in this application embodiment has a conductive layer 130 disposed between the conductor 120 and the contact surface 110b. The conductive layer 130 is insulated from the conductor 120 and the contact surface 110b and is spaced apart. After the touch body 110 wears down, the conductive layer 130 will be exposed first and then worn down. When the touch component 100 is used in a stylus, after the conductive layer 130 wears down, the resistance value of the conductive layer 130 changes or the circuit where the conductive layer 130 is located becomes open. The degree of wear of the touch body 110 can be judged based on the change in the resistance value of the conductive layer 130, so that the operator can replace the touch component 100 or the stylus. This reduces the risk of the conductor 120 inside the touch component 100 being exposed and rubbing against the touch surface of the electronic device, thus scratching the touch surface.
[0053] like Figure 2 As shown, in some embodiments, the touch component 100 includes multiple conductive layers 130 in the direction from the conductor 120 to the contact surface 110b, and the multiple conductive layers 130 are insulated and spaced apart.
[0054] Optionally, the touch component 100 may include two or more conductive layers 130. Conductors 120 point towards the contact surface 110b, and the multiple conductive layers 130 are spaced apart, each corresponding to a different wear depth of the touch body 110.
[0055] Thus, as the touch body 110 wears down, the conductive layer 130, which is closer to the contact surface 110b, is exposed and wears down first. The degree of wear of the touch body 110 can be determined based on the wear of the different conductive layers 130.
[0056] When the touch body 110 is applied to a stylus, different conductive layers 130 can be disconnected to make the stylus give different prompt information, so that the operator can determine the wear degree of the touch body 110. For example, when different conductive layers 130 are worn, the stylus can give different voice or prompt sound, or the touch screen of the electronic device electrically connected to the stylus can display different prompt pictures.
[0057] Therefore, the touch component 100 is provided with multiple conductive layers 130, and the multiple conductive layers 130 are insulated and spaced, which is beneficial to the operator to determine the wear degree of the touch body 110.
[0058] As shown in Figure 2 and Figure 3 In some embodiments, the conductive layer 130 includes multiple conductive areas 130a, and the multiple conductive areas 130a are insulated from each other and cover different areas of the conductive body 120.
[0059] The conductive layer 130 can include two, three, four or more conductive areas 130a, and different conductive areas 130a correspond to different areas of the conductive body 120. For example, along the circumference of the conductive body 120, the multiple conductive areas 130a are distributed in a fan shape. The multiple conductive areas 130a are insulated and spaced from each other, so that any disconnection of any one of the conductive areas 130a will not affect the on-off of the circuit of other conductive areas 130a.
[0060] The distance of different conductive areas 130a from the contact surface 110b can be the same, so that different conductive areas 130a correspond to different wear areas of the touch body 110. According to the disconnection or resistance change of different conductive areas 130a, the wear position of the touch body 110 can be determined, so as to timely adjust the pen holding posture, adjust the position of the contact surface 110b contacting and rubbing the touch surface of the electronic device, and reduce the risk of wear of the contact surface of the conductive body 120 and the touch surface of the electronic device.
[0061] Therefore, the conductive layer 130 includes multiple conductive areas 130a, and the multiple conductive areas 130a are insulated from each other, so that different conductive areas 130a cover different areas of the conductive body 120. After some of the conductive areas 130a are worn, the touch component 100 can be used by adjusting the pen holding posture, so as to reduce the risk of friction between the conductive body 120 and the touch surface of the electronic device, and improve the service life of the touch component 100.
[0062] As shown in Figure 2 , Figure 3 andFigure 4 As shown in some embodiments, the conductive layer 130 includes metal wires 131, which are arranged in a mesh shape around the through holes and in a direction parallel to the contact surface 110b.
[0063] The metal wires 131 have good conductivity, and the through holes formed by the metal wires 131 are large, which further reduces the shielding effect of the conductive layer 130 on the conductive body 120, and the metal wires 131 are relatively easy to be injection molded with the touch body 110 in the preparation process of the touch component 100.
[0064] The metal wires 131 are arranged in a mesh shape, and the through holes formed by the metal wires 131 are arranged in a mesh shape. The shape of the through holes can be a polygon, a ring, a three-ring, or other irregular shapes, which are not limited here and can be selected according to actual needs.
[0065] The metal wires 131 form the through holes, and the size of the through holes formed by the metal wires 131 should be appropriate to have a suitable spacing of the metal wires 131. After the touch body 110 is worn out, in the case that the touch body 110 in the through hole is worn out before the metal wires 131, the appropriate through hole is beneficial to ensure that the metal wires 131 are worn out before the conductive body 120, so as to realize the timely disconnection of the conductive layer 130.
[0066] The metal wires 131 are arranged in a direction parallel to the contact surface 110b, so the distance from any position of the metal wires 131 to the contact surface 110b is the same. In this way, most parts of the touch body 110 corresponding to the metal wires 131 are worn out to a predetermined distance, which will make the metal wires 131 exposed and worn out with the touch surface of the electronic device. Therefore, the area corresponding to the metal wires 131 of the touch body 110 is large, and the contact surface 110b in the area has a considerable distance from the metal wires 131. In the case that the metal wires 131 are worn out, the wear position and wear state of the contact surface 110b can be determined according to the wear position or wear degree of the metal wires 131.
[0067] In addition, after the metal wires 131 are disconnected, the corresponding conductive layer 130 has a greater influence on the disconnection or resistance value change, which is beneficial to more sensitively perceive the wear condition of the conductive layer 130.
[0068] Therefore, the conductive layer 130 including the metal wires 131 is beneficial to improve the process reliability in the processing of the touch component 100, and is also beneficial to more sensitively determine the wear condition of the touch body 110 through the resistance value change of the conductive layer 130 or the disconnection condition of the conductive layer 130.
[0069] As shown in some embodiments, the conductive layer 130 includes metal wires 131, which are arranged in a mesh shape around the through holes and in a direction parallel to the contact surface 110b. Figure 4 、 Figure 5 and Figure 6As shown, in some embodiments, the metal wires 131 are arranged in a rectangular grid, a ring grid, or a fan-shaped ring grid.
[0070] The metal wires 131 are arranged in an array along the extension direction of the conductive layer 130, but this does not mean that the metal wires 131 must be planar. The metal wires 131 can be arranged in a matrix array or in a circular array.
[0071] It is understandable that whether it is a rectangular grid, a ring grid, or a fan-shaped ring grid, the metal wires 131 can be arranged more regularly, and the metal wires 131 can be guaranteed to have a certain structural strength, reducing the phenomenon of misjudgment caused by damage to the metal wires 131 due to collisions or vibrations.
[0072] In addition, by arranging the metal wires 131 in a matrix pattern, the arrangement of the metal wires 131 becomes more regular. When the wear depth of the touch body 110 in different areas is roughly the same, the wear amount of the metal wires 131 can be roughly the same. This makes it easier to judge the wear state of the touch body 110 based on the resistance change or open circuit of the metal wires 131.
[0073] like Figure 7 As shown, in some embodiments, the touch component 100 has a decorative layer 140, which is disposed on the touch body 110 and located between the conductor 120 and the contact surface 110b.
[0074] Optionally, the decorative layer 140 may be located between the conductor 120 and the conductive layer 130, or the decorative layer 140 may be located between the conductive layer 130 and the contact surface 110b. There are no restrictions here, and the selection can be made according to actual needs.
[0075] Optionally, the decorative layer 140 can be any structure that can be recognized by the human eye. For example, the decorative layer 140 can be a plastic film with a certain color.
[0076] By setting a decorative layer 140 and positioning it between the contact surface 110b and the conductor, the decorative layer 140 will be exposed before the conductor 120 as the touch body 110 wears down. Since the decorative layer 140 can be seen by the human eye, the operator can clearly see the wear condition of the touch body 110, so as to adjust the pen grip or replace the touch component 100 in time.
[0077] Optionally, the touch component 100 can only include one decorative layer 140, or the touch component 100 includes multiple decorative layers 140 which are spaced apart from each other and have different patterns or colors, so that the operator can determine the wear condition of the touch body 110 according to the color or pattern of the exposed decorative layer 140.
[0078] Therefore, the touch component 100 is provided with the decorative layer 140, and the decorative layer 140 is arranged between the conductive body 120 and the contact surface 110b, so that the operator can more intuitively determine the wear condition of the touch body 110, and timely adjust the pen holding posture or replace the touch component 100, so as to further reduce the risk of scratching the touch surface of the electronic device due to the friction between the conductive body 120 and the touch surface of the electronic device.
[0079] In some embodiments, the end of the conductive body 120 towards the contact surface 110b is ellipsoidal, and the contact surface 110b is arranged in a shape following the end of the conductive body 120 towards the contact surface 110b.
[0080] The end of the conductive body 120 towards the contact surface 110b is ellipsoidal, so that the end of the conductive body 120 for transmitting electrical signals with the touch surface of the electronic device is ellipsoidal, and the contact surface 110b is also ellipsoidal. The ellipsoidal shape has a larger surface area, so that the surface of the contact surface 110b for contacting the touch surface of the electronic device has a larger area. During the process of contacting the touch surface 110b with the touch surface, since the contact surface 110b is arranged in a shape following the end of the conductive body 120 towards the contact surface 110b, any position of the contact surface 110b contacting the touch surface can realize the electrical connection between the conductive body 120 and the touch surface of the electronic device, so as to realize more fluent writing or touch operation on the touch surface.
[0081] Therefore, the end of the conductive body 120 towards the contact surface 110b is ellipsoidal, and the contact surface 110b is arranged in a shape following the end of the conductive body 120 towards the contact surface 110b, so that the contact surface 110b has a larger area for contacting the touch surface of the electronic device during the use of the touch component 100 for realizing the touch or writing operation on the touch surface of the electronic device. Therefore, when the touch component 100 is applied to a touch pen, the operator has more optional pen holding postures, and the convenience of the operator during writing or touch operation is improved. Since the contact surface 110b is arranged in a shape following the end of the conductive body 120 towards the contact surface 110b, the distance between the conductive body 120 and the contact surface 110b changes little when the contact position of the contact surface 110b and the touch surface changes, which is beneficial to maintaining the fluency of writing or touch when the operator changes the pen holding posture.
[0082] As Figure 8As shown, the stylus 10 provided by the embodiments of the present application comprises the touch component 100 provided by any of the above embodiments.
[0083] Optionally, the stylus 10 can be an active stylus or a passive stylus. The stylus 10 is used for writing or touch operation on a touch surface of an electronic device with touch function, such as a mobile phone, a tablet, a notebook, a television or a projector. The touch component 100 can be at least part of the nib of the stylus 10, and in the process of using the stylus 10, the contact surface 110b of the touch component 100 is in contact with the touch surface of the electronic device to realize writing or touch operation on the touch surface.
[0084] The stylus 10 provided by the embodiments of the present application adopts the touch component 100 provided by any of the above embodiments. In the process of writing on the touch surface of the electronic device by the stylus 10, as the nib wears out, the conductive layer 130 in the touch component 100 is exposed before the conductive body 120, and the conductive layer 130 is worn out on the touch surface. After the conductive layer 130 is worn out, the resistance of the conductive layer 130 changes. The stylus 10 can detect the resistance change of the conductive layer 130 to determine the wear state of the nib, so as to issue a prompt information before the conductive body 120 in the touch component 100 is exposed or before the conductive body 120 rubs against the touch surface, so as to replace the stylus 10 or the touch component 100 in time, and reduce the risk of scratching the touch surface by the conductive body 120 in the touch component 100.
[0085] Please continue to refer to Figure 8 In some embodiments, the stylus 10 further comprises a circuit board 11, which is electrically connected with the conductive layer 130 and is used for detecting the wear state of the conductive layer 130.
[0086] The circuit board 11 can be a chip or other component with integrated circuit. The circuit board 11 is electrically connected with the conductive layer 130, so that the related circuit in the circuit board 11 and the conductive layer 130 together form a series circuit. The circuit board 11 can also be integrated with a current sensor or a voltage sensor, and can determine the wear state of the conductive layer 130 by measuring the change amount of the resistance value of the conductive layer 130.
[0087] Exemplarily, when the conductive layer 130 is worn to break the series circuit loop formed by the conductive layer 130 and the circuit board 11, it can be considered that the resistance value of the conductive layer 130 is increased to infinity, and thus it is determined that the conductive layer 130 has been worn out and the same position of the touch component 100 cannot be used for writing or touch operation any more. Alternatively, after at least part of the conductive layer 130 is worn out, the series circuit loop formed by the conductive layer 130 and the circuit board 11 is not broken, but due to the partial damage of the conductive layer 130, the resistance value of the conductive layer 130 is changed, and the related components in the circuit board 11 can determine the wear of the conductive layer 130 according to the change of the resistance value of the conductive layer 130.
[0088] Therefore, the circuit board 11 is arranged to be electrically connected with the conductive layer 130, so that the change of the electrical property information of the conductive layer 130 can be detected in time by the circuit board 11, and the wear state of the touch component 100 can be determined according to the change of the electrical property information of the conductive layer 130, and the operator can be informed to replace the touch component 100 or the operator in time.
[0089] As shown in Figure 9 In some embodiments, the circuit board 11 is also electrically connected with the conductive body 120, so that the touch pen 10 can transmit signals to the touch device.
[0090] The circuit board 11 is also electrically connected with the conductive body 120, and the circuit board 11 and the conductive body 120 form a circuit loop together, so that the electrical property information of the conductive body 120 and the touch surface of the electronic device can be amplified by the circuit board 11, and the touch sensitivity of the touch pen 10 on the touch surface can be improved.
[0091] Exemplarily, a pressure sensor can be arranged on the circuit board 11, and the pressure sensor is electrically connected with the conductive body 120, so that when the pressure sensor senses that the pen tip contacts the touch surface, the conductive body 120 can send electrical property information to the touch surface, so as to more sensitively realize writing or touch operation on the touch surface.
[0092] In the embodiment in which the touch component 100 includes multiple conductive layers 130 arranged in multiple layers and spaced from each other, the multiple conductive layers 130 are electrically connected with the circuit board 11, and the conductive layers 130 are arranged in parallel with each other, so as to maintain the independence of the circuits of the conductive layers 130, and the specific state of the wear of the touch component 100 can be determined according to the resistance change of the different conductive layers 130.
[0093] Therefore, the circuit board 11 is also electrically connected with the conductive body 120, so that the touch pen 10 can be an active pen, and the touch sensitivity of the touch pen 10 on the touch panel can be further improved.
[0094] In some embodiments, the conductive layer 130 includes a plurality of conductive regions 130a, the plurality of conductive regions 130a are arranged to be insulated from each other, and different conductive regions 130a cover different areas of the conductive body 120. The plurality of conductive regions 130a are respectively electrically connected with the circuit board 11, and the plurality of conductive regions 130a are connected in parallel with each other.
[0095] In this way, different conductive regions 130a of the same layer form independent circuit loops with the circuit board 11 respectively, and the on-off of any one does not affect the on-off of other conductive regions 130a. Since different conductive regions 130a cover different areas of the conductive body 120, during the wear of the touch component 100, the wear position of the stylus tip of the stylus 10 can be determined according to the resistance change of different conductive regions 130a, so as to adjust the holding posture in time, change the wear position of the stylus tip and the touch surface, until all the conductive regions 130a are worn.
[0096] As shown in Figure 10 The stylus system 1 provided by the embodiments of the present application includes the stylus 10 provided by any of the above embodiments.
[0097] The stylus system 1 further includes a mobile phone, a tablet, a notebook or a television, etc. which has both display function and touch function. The stylus 10 and the touch surface of the electronic device perform information interaction, so as to realize the touch or writing operation of the stylus 10 on the touch surface.
[0098] The stylus system 1 provided by the embodiments of the present application has the same technical effects as the stylus 10 provided by any of the above embodiments, and thus will not be described here.
[0099] Please continue to refer to Figure 10 In some embodiments, the stylus system 1 further includes a touch device 20, and the touch device 20 includes a first communication module 21. The stylus 10 includes a detection module 12 and a second communication module 13 which are electrically connected. The detection module 12 is electrically connected with the conductive layer 130 and is used for detecting the wear of the conductive layer 130. The second communication module 13 is used for sending a wear signal to the first communication module 21 after detecting the wear of the conductive layer 130, so as to make the touch device 20 send corresponding prompt information.
[0100] The detection module 12 is electrically connected with the conductive layer 130 and is used for detecting the wear of the conductive layer 130. Therefore, the detection module 12 can detect the resistance change of the conductive layer 130, so as to determine the wear of the conductive layer 130. For example, when the resistance change of the conductive layer 130 exceeds a certain threshold, it can be determined that the conductive layer 130 is worn.
[0101] The detection module 12 sends the detected abrasion condition of the conductive layer 130 to a control module in the circuit board 11, and after the control module determines that the conductive layer 130 is abraded, the control module sends a corresponding abrasion signal to the second communication module 13 through the first communication module 21. After the second communication module 13 receives the abrasion signal, the touch device 20 controls to send a prompt information to prompt the abrasion condition of the stylus 10 through the touch device 20. The communication mode of the first communication module 21 and the second communication module 13 can be wireless communication.
[0102] Optionally, in the case that the touch device 20 has a display function, the touch device 20 can display a related icon in the form of a pop-up window to prompt the operator about the abrasion condition of the stylus 10. Alternatively, in the case that the touch device 20 has a voice function, the touch device 20 can also prompt the abrasion condition of the stylus 10 through voice prompt.
[0103] Therefore, the touch wall is provided with the second communication module 13, and information transmission is performed between the second communication module 13 and the first communication module 21 of the touch device 20, so that after the stylus 10 is abraded, the touch device 20 sends a related prompt information, which is not easily ignored by the operator, and the operator can pay attention to the related prompt information in time, thereby further reducing the risk of scratching the touch surface by the conductive body 120.
[0104] As shown in FIG. 1, Figure 11 In some embodiments, the touch device 20 further includes a display module 22, which is electrically connected to the first communication module 21 and displays a prompt information after the first communication module 21 receives the abrasion signal.
[0105] Specifically, after the first communication module 21 receives the abrasion signal, the display module 22 displays a prompt information through a pop-up window, an animation, a picture or other visual ways, so that the touch device 20 can more intuitively send a related prompt information, which is more easily noticed by the operator, and the stylus 10 or the touch device 20 can be replaced in time, thereby further reducing the risk of scratching the touch surface by the abrasion between the stylus 10 and the touch surface.
[0106] Although the present application has been described with reference to the preferred embodiments, various modifications can be made to it without departing from the scope of the application, and equivalent components can be substituted therefor. In particular, the technical features mentioned in each embodiment can be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
