[0043] The embodiment of the present application provides a touch panel, which can be packaged as a touch screen. The touch panel can further integrate a display function, and the touch panel with integrated display function can be called a touch display panel. Accordingly, the touch display panel can be packaged as a touch display screen. The touch panel of the embodiment of the present application can be applied to touch devices. Touch devices include but are not limited to various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc.

[0044] Figure 1 is a schematic diagram of the structure of a touch device according to an embodiment, referring to Figure 1 Taking the touch device as a mobile phone as an example, the touch device includes a touch display screen 10, a middle frame 20 and a back cover 30 arranged in sequence along the thickness direction. Among them, the middle frame 20 includes a frame body 21 and a frame 22 surrounding the side of the frame body 21. The frame 22 may be a conductive frame 22. Of course, in other embodiments, the touch device may not have a frame body 21. The touch display screen 10, the frame body 21 and the back cover 30 are stacked in sequence, and a receiving space is formed between the touch display screen 10 and the frame body 21, and between the frame body 21 and the back cover 30 to accommodate components such as a motherboard, a camera module, a receiver module, a battery, and various sensors. One side of the frame 22 is surrounded by the edge of the touch display screen 10, and the other side of the frame 22 is surrounded by the edge of the back cover 30 to form a complete appearance structure of the touch device.

[0045] The frame 22 includes a top edge and a bottom edge that are arranged opposite to each other, and a first side edge and a second side edge connected to the top edge and the bottom edge. The top edge is the side away from the ground when the user holds the touch device and uses the touch screen in portrait mode, and the bottom edge is the side facing the ground when the user holds the touch device and uses the touch screen in portrait mode. The first side edge is the left side edge when the user holds the touch device and uses the touch screen in portrait mode. The second side edge is the right side edge when the user holds the touch device and uses the touch screen in portrait mode.

[0046] The embodiment of the present application provides a touch panel integrated with a capacitive touch function and an electromagnetic touch function. Among them, the capacitive touch function is used to support the touch operation of the user's finger and the touch operation of the capacitive active pen, and the electromagnetic touch function is used to support the touch operation of the electromagnetic pen. Among them, the capacitive active pen includes a pen tip, a pressure sensor, a battery, a circuit board, and a main control chip, a charge and discharge control chip, a communication chip, etc. integrated on the circuit board, and the communication chip is, for example, a Bluetooth communication chip. The internal structure of the capacitive active pen is complex, so the overall volume is large, and there is no way to directly insert or integrate it into a mobile phone or tablet, which is inconvenient to carry. The electromagnetic pen includes a pen tip, a coil, a circuit board, and an energy storage capacitor, a charge and discharge control chip, a communication chip, etc. integrated on the circuit board, and the communication chip is, for example, a Bluetooth communication chip. Compared with the capacitive active pen, the electromagnetic pen does not require a battery, and the internal structure is simple, so it is small in size and easy to insert into the interior of the touch device.

[0047] The touch panel provided in the embodiment of the present application includes capacitive sensing electrodes and electromagnetic induction electrodes. Figure 2 is a schematic diagram of a capacitive sensing electrode 100 according to an embodiment. Figure 2 The capacitance sensing electrode 100 includes a plurality of first capacitance electrodes 110 extending along a first direction and a plurality of second capacitance electrodes 120 extending along a second direction.

[0048] The first direction and the second direction are different, and the first direction can be perpendicular to the second direction. For example, the first direction is horizontal, and the second direction is vertical. For another example, the first direction is vertical, and the second direction is horizontal. The horizontal direction can be understood as the direction from the first side of the touch device to the second side, and the vertical direction can be understood as the direction from the top side of the touch device to the bottom side. For ease of explanation, the following embodiments are described by taking the first direction as horizontal and the second direction as vertical as an example. It should be noted that Figure 2 The first capacitor electrode 110 and the second capacitor electrode 120 are both in a strip-shaped structure. Figure 2 It is only used to illustrate the extension direction of the first capacitor electrode 110 and the second capacitor electrode 120. The first capacitor electrode 110 and the second capacitor electrode 120 may also adopt other regular or irregular shapes, which are not limited here. The specific structure of the first capacitor electrode 110 and the second capacitor electrode 120 will be described in subsequent embodiments.

[0049] One of the first capacitor electrode 110 and the second capacitor electrode 120 is a capacitor transmitting electrode, and the other is a capacitor receiving electrode. For example, the first capacitor electrode 110 is a capacitor transmitting electrode, and the second capacitor electrode 120 is a capacitor receiving electrode. For another example, the first capacitor electrode 110 is a capacitor receiving electrode, and the second capacitor electrode 120 is a capacitor transmitting electrode. When a finger or a capacitive active pen touches or approaches the touch panel, a coupling capacitor is formed with the surface of the touch panel, thereby causing a slight change in the current to characterize the touch operation of the finger or the capacitive active pen. Specifically, the capacitor transmitting electrode sends out a capacitive excitation signal in turn, and multiple capacitor receiving electrodes receive the capacitive touch signal at the same time, so that the capacitance value at the intersection of the capacitor transmitting electrode and each capacitor receiving electrode can be obtained. After completing the scan of each capacitor transmitting electrode, the coordinates of one or more touch points can be calculated based on the two-dimensional capacitance value data of the touch panel.

[0050] Furthermore, the first capacitor electrode 110 and the second capacitor electrode 120 are both connected to the touch chip. In the case where the touch panel further integrates a display function, the touch chip can be integrated with the display driver chip (Display Driver Integrated Circuit, DDIC) to form a touch display chip (Touch and Display Driver Integrated Circuit, TDIC). The capacitor transmitting electrode can send a capacitor excitation signal under the control of the touch chip, and the capacitor receiving electrode transmits the received capacitor touch signal to the touch chip so that the touch chip obtains the coordinates of the touch point. Among them, the touch chip can be set close to the bottom edge of the touch device. The first capacitor electrode 110 extending in the horizontal direction can be partially connected to the touch chip by the end close to the first side, and the other part can be connected to the touch chip by the end close to the second side. The number of the above two parts of the first capacitor electrode 110 can be the same or similar to balance the number of touch lines on the left and right sides and reduce the width of the screen frame 22. The second capacitor electrode 120 extending in the longitudinal direction is connected to the touch chip at an end portion close to the bottom edge, so as to shorten the length of the touch wiring between the second capacitor electrode 120 and the touch chip.

[0051] Figure 3 FIG. 1 is a global schematic diagram of a capacitive sensing electrode 100 and an electromagnetic induction electrode 200 according to an embodiment of the present invention. Figure 3 The electromagnetic induction electrode 200 includes a plurality of first electromagnetic electrodes 210 and a plurality of second electromagnetic electrodes 220. The electromagnetic induction electrode 200 is spaced apart from the capacitive induction electrode 100. The electromagnetic induction electrode 200 may also be referred to as an electromagnetic induction coil.

[0052] One of the first electromagnetic electrode 210 and the second electromagnetic electrode 220 is an electromagnetic transmitting electrode, and the other is an electromagnetic receiving electrode. For example, the first electromagnetic electrode 210 is an electromagnetic transmitting electrode, and the second electromagnetic electrode 220 is an electromagnetic receiving electrode. For another example, the first electromagnetic electrode 210 is an electromagnetic receiving electrode, and the second electromagnetic electrode 220 is an electromagnetic transmitting electrode. The electromagnetic transmitting electrode is used to send electromagnetic waves to the electromagnetic pen. When the electromagnetic pen with a resonant circuit moves on the touch panel provided with an electromagnetic induction layer, the resonant circuit is stimulated by the electromagnetic excitation signal emitted by the electromagnetic transmitting electrode, and emits a resonant signal as an electromagnetic touch signal. The electromagnetic receiving electrode is used to receive the electromagnetic touch signal generated after the electromagnetic pen resonates with the electromagnetic wave sent by the electromagnetic transmitting electrode, thereby determining the position of the electromagnetic pen on the screen.

[0053] At least part of the electromagnetic induction electrodes 200 are arranged in the same layer as the capacitive sensing electrodes 100. Specifically, multiple electromagnetic transmitting electrodes in the electromagnetic induction electrodes 200 may be arranged in the same layer and spaced apart from the capacitive sensing electrodes 100, or multiple electromagnetic receiving electrodes in the electromagnetic induction electrodes 200 may be arranged in the same layer and spaced apart from the capacitive sensing electrodes 100, or multiple electromagnetic transmitting electrodes and multiple electromagnetic receiving electrodes in the electromagnetic induction electrodes 200 may be arranged in the same layer and spaced apart from the capacitive sensing electrodes 100, which is not limited in this embodiment. By arranging at least part of the electromagnetic induction electrodes 200 in the same layer as the capacitive sensing electrodes 100, the number of film layers required to be arranged in the touch panel can be reduced, thereby facilitating miniaturization and thinness of the touch panel.

[0054] Furthermore, at least part of the electromagnetic induction electrodes 200 disposed in the same layer as the capacitive sensing electrodes 100 is disposed inside the capacitive sensing electrodes 100. The touch panel can be divided into a plurality of touch control units arranged in an array. Figure 4 for Figure 3 A schematic diagram of a touch unit in a touch panel of an embodiment, referring to Figure 4, at least part of the capacitive sensing electrode 100 is a circumferentially closed structure, and a cavity is formed inside. Part of the electromagnetic induction electrode 200 is arranged in the above cavity and is spaced apart from the peripheral capacitive sensing electrode 100. By arranging at least part of the electromagnetic induction electrode 200 arranged in the same layer as the capacitive sensing electrode 100 inside the capacitive sensing electrode 100, the space within the layer can be fully utilized, and the problem of excessive gap between electrodes caused by the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 avoiding each other can be reduced, thereby increasing the electrode area of ​​the capacitive sensing electrode 100 and the electromagnetic induction electrode 200, so as to improve the sensitivity and accuracy of touch control through electrodes with larger areas. Moreover, the arrangement method of this embodiment can make the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 arranged in a more regular manner. The regular arrangement method can not only make the electrode arrangement method in each touch control unit the same, but also facilitate the data processing of the touch control chip. The regular arrangement can also make the absorption and reflection capabilities of the light beam at various locations on the touch panel similar, thereby reducing the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device. Figure 4 The structures of the capacitive touch electrodes and the electromagnetic touch electrodes shown are only for exemplary descriptions. The capacitive sensing electrodes 100 and the electromagnetic sensing electrodes 200 may also be provided in other structures, which are not limited here.

[0055] In the embodiment of the application, by integrating the capacitive sensing electrode 100 and the electromagnetic sensing electrode 200 in the touch panel, the capacitive touch function and the electromagnetic touch function can be combined into one, so that the touch panel can be applied to different types of styluses. Moreover, by setting at least part of the electromagnetic sensing electrode 200 in the same layer as the capacitive sensing electrode 100, the electromagnetic sensing electrode 200 film layer that needs to be separately laminated and set in the related art can be omitted, and the number of film layers required to be set in the touch panel can be reduced, thereby improving the user's hand touch operation while reducing the impact on the cost, thickness and foldability of the touch panel. In addition, by setting at least part of the electromagnetic sensing electrode 200 set in the same layer as the capacitive sensing electrode 100 inside the capacitive sensing electrode 100, the space within the layer can be fully utilized, and the sensitivity and accuracy of touch sensing can be improved through electrodes with a larger area. It can also make the capacitive sensing electrode 100 and the electromagnetic sensing electrode 200 arranged in a more regular manner, which is beneficial to the data processing of the touch chip, and reduces the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device.

[0056] In one embodiment, the extension direction of the second electromagnetic electrode 220 is the same as the extension direction of the second capacitor electrode 120. For example, the second electromagnetic electrode 220 and the second capacitor electrode 120 both extend along the first direction, or the second electromagnetic electrode 220 and the second capacitor electrode 120 both extend along the second direction. This embodiment is described by taking the second electromagnetic electrode 220 and the second capacitor electrode 120 both extend along the second direction as an example.

[0057] The second electromagnetic electrode 220 is arranged in the same layer as the second capacitor electrode 120. By arranging the second electromagnetic electrode 220 and the second capacitor electrode 120 in the same layer, the number of film layers required to be arranged in the touch panel can be reduced, which is conducive to the miniaturization and thinness of the touch panel. Further, at least part of the second electromagnetic electrode 220 is located inside the second capacitor electrode 120. By arranging at least part of the second sensing electrode inside the second capacitor electrode 120, the space in the layer can be fully utilized, and the problem of excessive gap between electrodes caused by the second electromagnetic electrode 220 and the second capacitor electrode 120 avoiding each other can be reduced, so that the electrode area of ​​the second electromagnetic electrode 220 and the second capacitor electrode 120 can be increased, so as to improve the sensitivity and accuracy of touch sensing through electrodes with larger areas. Moreover, the arrangement method of this embodiment can make the second electromagnetic electrode 220 and the second capacitor electrode 120 arranged in a more regular manner. The regular arrangement method can not only make the electrode arrangement method in each touch unit the same, but also facilitate the data processing of the touch chip. The regular arrangement can also make the absorption and reflection capabilities of the light beam at various locations on the touch panel similar, thereby reducing the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device.

[0058] Figure 5 for Figure 4 The schematic diagram of the second capacitor electrode 120 of the embodiment is shown in FIG. Figure 5 , the second capacitor electrode 120 includes a plurality of capacitor electrode segments 121, and adjacent capacitor electrode segments 121 are connected through the first bridging structure 410. Exemplarily, in a touch unit, the second capacitor electrode 120 may be, but is not limited to, divided into two segments, three segments, etc. In the case where the second capacitor electrode 120 of a touch unit includes three capacitor electrode segments 121, a touch unit includes two first bridging structures 410. By dividing the second capacitor electrode 120 into multiple segments, the boundary length of the junction between the first capacitor electrode 110 and the second capacitor electrode 120 can be increased, and the coupling capacitance between the first capacitor electrode 110 and the second capacitor electrode 120 is increased, so that the capacitance change caused by the touch unit being touched can be increased, and then the capacitive touch signal can be enhanced, the phenomenon of disconnection or touch jitter can be reduced, and the touch performance of the touch panel can be improved.

[0059] Further, Figure 6 for Figure 5 The cross-sectional view of the second capacitor electrode 120 along the AA direction of the embodiment is shown in FIG. Figure 6 In one embodiment, the touch panel is stacked with a first metal layer 11, an insulating layer 12 and a second metal layer 13. Among them, the insulating layer 12 can be made of an insulating material, for example, an inorganic material. Exemplarily, the insulating layer 12 can be made of at least one of Al2O3, TiO2, SiNx, SiCNx, SiOx, etc. to ensure the insulating effect of the insulating layer 12 and increase the water blocking function of the insulating layer 12. At least one of the first metal layer 11 and the second metal layer 13 can be made of a metal mesh. The metal mesh is a mesh structure made of metal wire or metal foil. The metal mesh has a high transparency, so it has little effect on the display effect of the touch device and does not affect the user's viewing experience. Moreover, the metal mesh has the characteristics of excellent conductivity, bendability and lightweight, so it is suitable for touch devices such as mobile phones that have bending requirements and portability requirements.

[0060] The second capacitor electrode 120 is located in the second metal layer 13, and a plurality of capacitor electrode segments 121 are arranged in a spaced relationship within the second metal layer 13. The touch panel includes a first via hole 310 and a first bridge structure 410. Figure 4 The circular structure in the capacitor electrode segment 121 is the first via hole 310. The first via hole 310 is located in the insulating layer 12, and the first via hole 310 penetrates from the surface of the insulating layer 12 close to the first metal layer 11 to the surface close to the second metal layer 13. The first bridge structure 410 is located in the first metal layer 11, and the two ends of the first bridge structure 410 are respectively connected to the two first via holes 310, and the adjacent capacitor electrode segments 121 are connected to the first bridge structure 410 through the first via holes 310 to conduct. For example, Figure 6 The first bridging structure 410 on the left side is used to connect the right end of the capacitor electrode segment 121 on the left side with the left end of the capacitor electrode segment 121 in the middle, and the first bridging structure 410 on the right side is used to connect the right end of the capacitor electrode segment 121 in the middle with the left end of the capacitor electrode segment 121 on the left side, so as to make multiple capacitor electrode segments 121 in the same touch unit conductive.

[0061] Further, continue to refer to Figure 4, two first vias 310 may be respectively provided at both ends of a capacitor electrode segment 121, and the outer contour of the capacitor electrode segment 121 is an axisymmetric shape, and the extension direction of the symmetry axis is parallel to the first direction. The two first vias 310 may also be symmetrically arranged about the symmetry axis of the capacitor electrode segment 121, so that the impedance of each part of the capacitor electrode segment 121 is similar. In some embodiments, the number of first vias 310 may be flexibly set, for example, one or three first vias 310 may be respectively provided at both ends of a capacitor electrode segment 121, which is not limited here.

[0062] Further, continue to refer to Figure 4 The first bridge structure 410 is extended in a bent manner to avoid other conductive structures in the first metal layer 11 and prevent a short circuit in the first metal layer 11. In some embodiments, the first bridge structure 410 may be extended in a straight line, a curved line, etc., which are not limited here.

[0063] It should be noted that if Figure 3 As shown, for any two touch control units adjacent in the second direction, the capacitor electrode segment 121 at the bottom of one touch control unit is connected to the capacitor electrode segment 121 at the top of another adjacent touch control unit, so that multiple capacitor electrode segments 121 in different touch control units located in the same column are continuously conductive in the second direction to receive capacitor excitation signals from the touch control chip or transmit capacitor touch signals to the touch control chip.

[0064] Figure 7 for Figure 4 A schematic diagram of the first capacitor electrode 110 of the embodiment, Figure 8 FIG7 is a cross-sectional view of the first capacitor electrode 110 along the BB direction according to the embodiment of FIG7. Figure 7 and Figure 8 , the first capacitor electrodes 110 are all located in the second metal layer 13 , and the first capacitor electrodes 110 are continuously conductive in the first direction without providing a bridge structure in the first metal layer 11 .

[0065] Combined with reference Figure 5 and Figure 7, the intersection of the first bridge structure 410 and the second capacitor electrode 120 can be graphically designed to reduce the overlapping area between the orthographic projection of the second capacitor electrode 120 in the first metal layer 11 and the first bridge structure 410, thereby reducing the coupling capacitance between the two, reducing the interference between the first capacitor electrode 110 and the second capacitor electrode 120, and thus improving the accuracy of capacitive touch. It should be noted that the graphical method of the first bridge structure 410 and the second capacitor electrode 120 shown in the figure is only for exemplary description, and other graphical methods that can reduce the coupling capacitance also belong to the protection scope of this embodiment and are not described here.

[0066] In the embodiment of the application, by setting both the first capacitor electrode 110 and the second capacitor electrode 120 in the second metal layer 13, the utilization rate of the second metal layer 13 can be improved. In addition, by breaking the second capacitor electrode 120 into a plurality of capacitor electrode segments 121, and connecting to the first bridge structure 410 located in the first metal layer 11 by setting a first via 310 in the insulating layer 12, normal conduction between the plurality of capacitor electrode segments 121 arranged along the second direction can be ensured, and short circuit between the first capacitor electrode 110 and the second capacitor electrode 120 set in the same layer can be avoided, thereby improving the reliability of capacitive touch.

[0067] Continue to refer Figure 6 and Figure 8 In one embodiment, the touch panel may further include a substrate 16. The substrate 16 is located on the side of the first metal layer 11 away from the insulating layer 12. That is, the first metal layer 11 is disposed on the side of the insulating layer 12 close to the substrate 16, and the second insulating layer 12 is disposed on the side of the insulating layer 12 away from the substrate 16. In the embodiment of the application, by disposing the second metal layer 13 away from the substrate 16 and disposing the second capacitor electrode 120 on the second metal layer 13, the distance between the finger or the capacitor active pen and the second metal layer 13 can be shortened, and other metal layers between the finger or the capacitor active pen and the second metal layer 13 can be reduced, thereby reducing the interference of other metal layers on the second capacitor electrode 120 when transmitting or receiving capacitive touch-related signals, thereby improving the accuracy and sensitivity of the touch device. It can be understood that in other embodiments, the substrate 16 is located on the side of the first metal layer 11 close to the insulating layer 12. That is, the first metal layer 11 is disposed on the side of the insulating layer 12 away from the substrate 16, and the second insulating layer 12 is disposed on the side of the insulating layer 12 close to the substrate 16, which is not limited in this embodiment.

[0068] Continue to refer Figure 4In one embodiment, the orthographic projection of the capacitive sensing electrode 100 on the substrate 16 is staggered from the orthographic projection of the electromagnetic induction electrode 200 on the substrate 16, and they are arranged at intervals from each other. That is, the orthographic projections of the first capacitive electrode 110, the second capacitive electrode 120, the first electromagnetic electrode 210, and the second electromagnetic electrode 220 on the substrate 16 do not overlap with each other. The above arrangement can make the distance between the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 larger, thereby reducing the coupling capacitance between the capacitive sensing electrode 100 and the electromagnetic induction electrode 200, reducing the interference between the capacitive sensing electrode 100 and the electromagnetic induction electrode 200, and improving the touch accuracy of the capacitive touch and electromagnetic touch of the touch panel.

[0069] Fig. 9 FIG. 1 is a schematic diagram of a film layer of a capacitive sensing electrode 100 and an electromagnetic induction electrode 200 according to an embodiment of the present invention. Fig. 9 In one embodiment, the first capacitor electrode 110 and the second capacitor electrode 120 in the capacitive sensing electrode 100 are both located in the second metal layer 13, and the first electromagnetic electrode 210 and the second electromagnetic electrode 220 in the electromagnetic induction electrode 200 are both located in the second metal layer 13. The first bridge structure 410 is located in the first metal layer 11. In the embodiment of the application, the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 are all arranged in the second metal layer 13, which can maximize the space utilization in the second metal layer 13. Moreover, the electromagnetic induction electrode 200 and the capacitive sensing electrode 100 can be prepared and formed simultaneously during the preparation process, so that the electromagnetic induction electrode 200 and the capacitive sensing electrode 100 with staggered orthographic projections can be naturally formed, without performing alignment operations in different process steps to stagger the electromagnetic induction electrode 200 and the capacitive sensing electrode 100, thereby reducing the process difficulty of preparing the electromagnetic induction electrode 200 and the capacitive sensing electrode 100 and improving the yield of the touch panel.

[0070] In one embodiment, the second electromagnetic electrode 220 is located in the second metal layer 13, and the second electromagnetic electrode 220 includes a plurality of electromagnetic electrode segments 221. The touch panel also includes a second via hole 320 and a second bridge structure 420. Figure 4 , the circular structure in the electromagnetic electrode segment 221 is the second via hole 320. The second via hole 320 is located in the insulating layer 12, and the second via hole 320 penetrates from the surface of the insulating layer 12 close to the first metal layer 11 to the surface close to the second metal layer 13. The second bridge structure 420 is located in the first metal layer 11, and the two ends of the second bridge structure 420 are respectively connected to the two second via holes 320, and the adjacent electromagnetic electrode segments 221 are connected to the second bridge structure 420 through the second via holes 320 to be conductive.

[0071] Further, continue to refer to Figure 4A second via hole 320 is provided at each end of an electromagnetic electrode segment 221. In some embodiments, the number of the second via holes 320 can be flexibly set. For example, two second via holes 320 are provided at each end of an electromagnetic electrode segment 221. This is not limited here.

[0072] It should be noted that, continue to refer to Figure 4 For any two touch control units adjacent to each other in the second direction, the electromagnetic electrode segment 221 at the bottom of one touch control unit is connected to the electromagnetic electrode segment 221 at the top of another adjacent touch control unit, so that multiple electromagnetic electrode segments 221 in different touch control units in the same column are continuously conducted in the second direction to receive electromagnetic excitation signals from the touch control chip or transmit electromagnetic touch signals to the touch control chip.

[0073] In the embodiment of the application, the electromagnetic electrode segment 221 is located inside the capacitor electrode segment 121 and is spaced apart from the capacitor electrode segment 121. Specifically, an electromagnetic electrode segment 221 can be respectively arranged inside each capacitor electrode segment 121. By locating the electromagnetic electrode segment 221 inside the capacitor electrode segment 121, the space within the second metal layer 13 can be fully utilized, and the problem of excessive gap between electrodes caused by the electromagnetic electrode segment 221 and the capacitor electrode segment 121 avoiding each other can be reduced, so that the electrode area of ​​the electromagnetic electrode segment 221 and the capacitor electrode segment 121 can be increased, so as to improve the sensitivity and accuracy of touch sensing through electrodes with larger areas. Moreover, the arrangement method of this embodiment can make the electromagnetic electrode segment 221 and the capacitor electrode segment 121 arranged in a more regular manner. The regular arrangement method can not only make the electrode arrangement method in each touch control unit the same, but also facilitate the data processing of the touch control chip. The regular arrangement can also make the absorption and reflection capabilities of the light beam at various locations on the touch panel similar, thereby reducing the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device.

[0074] In one embodiment, part of the electromagnetic induction electrodes 200 are located in the first metal layer 11, and the electromagnetic induction electrodes 200 located in the first metal layer 11 are staggered with the first bridge structure 410. Further, one of the first electromagnetic electrode 210 and the second electromagnetic electrode 220 is located in the first metal layer 11, and the other is located in the second metal layer 13. Fig.10 FIG. 2 is a second schematic diagram of the film layers of the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 according to an embodiment of the present invention. Fig.10The first capacitor electrode 110 and the second capacitor electrode 120 in the capacitive sensing electrode 100 are both located in the second metal layer 13, and the second electromagnetic electrode 220 in the electromagnetic induction electrode 200 is located in the second metal layer 13. The first electromagnetic electrode 210 in the electromagnetic induction electrode 200 is located in the first metal layer 11, and the first bridge structure 410 is located in the first metal layer 11. Fig.11 FIG. 3 is a third schematic diagram of the film layers of the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 according to an embodiment of the present invention. Fig.11 The first capacitor electrode 110 and the second capacitor electrode 120 in the capacitive sensing electrode 100 are both located in the second metal layer 13, and the first electromagnetic electrode 210 in the electromagnetic induction electrode 200 is located in the second metal layer 13. The second electromagnetic electrode 220 in the electromagnetic induction electrode 200 is located in the first metal layer 11, and the first bridge structure 410 is located in the first metal layer 11.

[0075] It is understandable that the sensing electrodes provided in each metal layer can be flexibly selected according to the arrangement density of the sensing electrodes and the first bridge structure 410 in the first metal layer 11 and the second metal layer 13, so as to ensure that the interference between the capacitive sensing electrode 100 and the electromagnetic sensing electrode 200 is small and the touch accuracy requirement is met. In some embodiments, part of the first electromagnetic electrodes 210 can be provided in the first metal layer 11, and another part of the first electromagnetic electrodes 210 can be provided in the second metal layer 13, or part of the second electromagnetic electrodes 220 can be provided in the first metal layer 11, and another part of the second electromagnetic electrodes 220 can be provided in the second metal layer 13, which is not limited here.

[0076] In one embodiment, the second capacitor electrode 120 includes a second branch connection portion 122 and a plurality of second branch electrodes 123 spaced apart along the first direction, and the second branch connection portion 122 is respectively connected to the ends of the plurality of second branch electrodes 123 so that the plurality of second branch electrodes 123 transmit the same capacitor excitation signal or the same capacitor touch signal together. Figure 4 The touch unit shown includes a second capacitor electrode 120, and the second capacitor electrode 120 includes three second branch electrodes 123. It is understandable that a second capacitor electrode 120 may include any number of second branch electrodes 123, for example, two, three or four second branch electrodes 123, which is not limited in this embodiment. By dividing the second capacitor electrode 120 into a plurality of second branch electrodes 123, the boundary length of the junction between the first capacitor electrode 110 and the second capacitor electrode 120 can be increased, and the coupling capacitance between the first capacitor electrode 110 and the second capacitor electrode 120 is increased, so that the capacitance change caused by the touch unit being touched can be increased, and then the capacitive touch signal can be enhanced, the phenomenon of disconnection or touch jitter can be reduced, and the touch performance of the touch panel can be improved.

[0077] For example, referring to Figure 3 , a second capacitor electrode 120 includes a second branch connection portion 122, the second branch connection portion 122 is connected to the end of each second branch electrode 123 close to the touch chip, and the second branch electrode 123 is also connected to the touch chip, so that each second branch electrode 123 is electrically connected to the touch chip. In another exemplary embodiment, a second capacitor electrode 120 includes two second branch connection portions 122, one of which is connected to the end of each second branch electrode 123 close to the touch chip, and the other second branch connection portion 122 is connected to the end of each second branch electrode 123 away from the touch chip. By providing two second branch connection portions 122, the current distribution on each second branch connection portion 122 in the same second capacitor electrode 120 can be made more balanced, thereby improving the sensing accuracy of the capacitive sensing electrode 100.

[0078] In one embodiment, each second branch electrode 123 has a second electromagnetic electrode 220 disposed therein. Figure 4 The touch unit shown includes three second electromagnetic electrodes 220. By providing the second electromagnetic electrode 220 inside each second electrode branch, a larger number of second electromagnetic electrodes 220 can be provided in the touch panel, so that the arrangement density of the second electromagnetic electrodes 220 is higher, thereby improving the touch panel's ability to distinguish the writing position of the electromagnetic pen and improving the accuracy of the recognized electromagnetic writing coordinates. It can be understood that in some embodiments, the second electromagnetic electrodes 220 can also be provided only inside some of the second branch electrodes 123. For example, the total number of second electromagnetic electrodes 220 in the touch panel can be half of the total number of second branch electrodes 123, and as shown in FIG. Fig.12 As shown, the second electromagnetic electrodes 220 are alternately arranged in each second branch electrode 123 .

[0079] In one embodiment, the extension direction of the first electromagnetic electrode 210 is the same as the extension direction of the first capacitor electrode 110. For example, the first electromagnetic electrode 210 and the first capacitor electrode 110 both extend in the horizontal direction, or the first electromagnetic electrode 210 and the first capacitor electrode 110 both extend in the longitudinal direction. This embodiment is described by taking the first electromagnetic electrode 210 and the first capacitor electrode 110 both extend in the horizontal direction as an example.

[0080] The first electromagnetic electrode 210 is arranged in the same layer as the first capacitor electrode 110. By arranging the first electromagnetic electrode 210 and the first capacitor electrode 110 in the same layer, the number of film layers required to be arranged in the touch panel can be reduced, which is conducive to the miniaturization and thinness of the touch panel. Further, at least part of the first electromagnetic electrode 210 is located inside the first capacitor electrode 110. By arranging at least part of the first sensing electrode inside the first capacitor electrode 110, the space in the layer can be fully utilized, and the problem of excessive gap between electrodes caused by the first electromagnetic electrode 210 and the first capacitor electrode 110 avoiding each other can be reduced, so that the electrode area of ​​the first electromagnetic electrode 210 and the first capacitor electrode 110 can be increased, so as to improve the sensitivity and accuracy of touch sensing through electrodes with larger areas. Moreover, the arrangement method of this embodiment can make the first electromagnetic electrode 210 and the first capacitor electrode 110 arranged in a more regular manner. The regular arrangement method can not only make the electrode arrangement method in each touch unit the same, but also facilitate the data processing of the touch chip. The regular arrangement can also make the absorption and reflection capabilities of the light beam at various locations on the touch panel similar, thereby reducing the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device.

[0081] In one embodiment, the first capacitor electrode 110 includes a first branch connection portion 111 and a plurality of first branch electrodes 112 spaced apart along a second direction, wherein the first branch connection portion 111 is respectively connected to ends of the plurality of first branch electrodes 112 so that the plurality of first branch electrodes 112 transmit the same capacitor excitation signal or the same capacitor touch signal together. Figure 4 The touch unit shown includes a first capacitor electrode 110, and the first capacitor electrode 110 includes three first branch electrodes 112. It is understandable that a first capacitor electrode 110 may include any number of first branch electrodes 112, for example, two, three or four first branch electrodes 112, which is not limited in this embodiment. By dividing the first capacitor electrode 110 into a plurality of first branch electrodes 112, the boundary length of the junction between the first capacitor electrode 110 and the second capacitor electrode 120 can be increased, and the coupling capacitance between the first capacitor electrode 110 and the second capacitor electrode 120 can be increased, so that the capacitance change caused by the touch unit being touched can be increased, and then the capacitive touch signal can be enhanced, the phenomenon of disconnection or touch jitter can be reduced, and the touch performance of the touch panel can be improved.

[0082] For example, referring to Figure 3, a first capacitor electrode 110 includes a first branch connection portion 111, the first branch connection portion 111 is connected to the left end portion or the right end portion of each first branch electrode 112, and the first branch electrode 112 is also connected to the touch chip, so that each first branch electrode 112 is electrically connected to the touch chip. In another exemplary embodiment, a first capacitor electrode 110 includes two first branch connection portions 111, one of which is connected to the left end portion of each first branch electrode 112, and the other first branch connection portion 111 is connected to the right end portion of each first branch electrode 112 away from the touch chip. By providing two first branch connection portions 111, the current distribution on each first branch connection portion 111 in the same first capacitor electrode 110 can be made more balanced, thereby improving the sensing accuracy of the capacitive sensing electrode 100.

[0083] In one embodiment, at least part of the first electromagnetic electrode 210 is located in the first gap between two adjacent first branch electrodes 112. Specifically, when a first capacitor electrode 110 is divided into n first branch electrodes 112, a touch control unit may include n-1 first electromagnetic electrodes 210. For example, Figure 4 In the case where the first capacitor electrode 110 is divided into three first branch electrodes 112, a touch unit may include two first electromagnetic electrodes 210. By locating at least part of the first electromagnetic electrode 210 in the first gap between two adjacent first branch electrodes 112, the space within the second metal layer 13 can be fully utilized, and the problem of excessive gap between electrodes caused by the mutual avoidance of the first electromagnetic electrode 210 and the first branch electrode 112 can be reduced, so that the electrode area of ​​the first electromagnetic electrode 210 and the first branch electrode 112 can be increased, so as to improve the sensitivity and accuracy of touch sensing through electrodes with larger areas. Moreover, the setting method of this embodiment can arrange the first electromagnetic electrode 210 and the first branch electrode 112 in a more regular manner. The regular arrangement method can not only make the electrode arrangement method in each touch unit the same, which is beneficial to the data processing of the touch chip. The regular arrangement method can also make the absorption and reflection capabilities of the light beam at various locations of the touch panel similar, thereby reducing the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device.

[0084] In one embodiment, the first capacitor electrode 110 includes a first strip-shaped electrode extending in a first direction, and the second capacitor electrode 120 includes a second strip-shaped electrode extending in a second direction. In the embodiment of the application, the first capacitor electrode 110 is configured as a strip-shaped electrode, which can effectively reduce the impedance value of the electrode and shorten the current flow path. At the same time, it can also simplify the structure and layout of the electrode pattern in the touch panel, facilitate the production of the touch panel, and thus improve the production yield.

[0085] In one embodiment, continue to refer to Figure 4 , the touch panel also includes a floating electrode 500. The floating electrode 500 is located in the second capacitor electrode 120 layer, and the floating electrode 500 is spaced apart from the first capacitor electrode 110 and the second capacitor electrode 120 respectively. The floating electrode 500 refers to an electrode that is spaced apart from other capacitive sensing electrodes 100 and electromagnetic induction electrodes 200 on all sides, thereby being in a "floating" state. The floating electrode 500 can both isolate the first capacitor electrodes 110 in two adjacent touch units in the second direction to avoid interference between the first capacitor electrodes 110 in adjacent rows. The floating electrode 500 can also be used to adjust the mutual capacitance between the first capacitor electrode 110 and the second capacitor electrode 120, so that the capacitance between the first capacitor electrode 110 and the second capacitor electrode 120 is in a suitable range. The suitable mutual capacitance range is, for example, 0.5pF to 1pF.

[0086] Fig.13 FIG. 1 is a global schematic diagram of a capacitive sensing electrode 100 according to an embodiment. To simplify the drawings, Fig.13 The electromagnetic induction electrodes 200 in the touch panel are not shown. Fig.14 for Fig.13 One of the structural diagrams of a touch unit in the embodiment, combined with reference to Fig.13 and Fig.14 In one embodiment, the first capacitor electrode 110 includes a plurality of first diamond structures 113 arranged in a first direction and connected to each other, and the second capacitor electrode 120 includes a plurality of second diamond structures 124 arranged in a second direction and connected to each other. The centers of the first diamond structures 113 are arranged in an array, the centers of the second diamond structures 124 are arranged in an array, and the connection points of the first diamond structures 113 and the connection points of the second diamond structures 124 are arranged correspondingly. The connection points of the first diamond structures 113 and the connection points of the second diamond structures 124 are arranged correspondingly, which means that the center of the connection point of the first diamond structure 113 and the center of the connection point of the second diamond structure 124 coincide with the orthographic projection of the center of the connection point of the first diamond structure 113 and the center of the connection point of the second diamond structure 124 on the substrate 16. In the embodiment of the application, by adopting a diamond-shaped capacitor electrode, it is easier to be compatible with the solutions in the related art, thereby reducing the cost of modifying the shape of the capacitor sensing electrode 100.

[0087] In one embodiment, the first electromagnetic electrode 210 includes a plurality of first electromagnetic induction portions 211 and a plurality of first electromagnetic connection portions 212 alternately arranged in a first direction, the two ends of a first electromagnetic connection portion 212 are respectively connected to two first electromagnetic induction portions 211, the first electromagnetic induction portion 211 is arranged correspondingly to the first rhombus structure 113, the first electromagnetic induction portion 211 is located inside the corresponding first rhombus structure 113, and is arranged at intervals from the first rhombus structure 113. The first electromagnetic induction portion 211 is arranged correspondingly to the first rhombus structure 113, which means that the center of the first electromagnetic induction portion 211 coincides with the orthographic projection of the center of the first rhombus structure 113 on the substrate 16. In the embodiment of the application, by setting the first electromagnetic connection portion 212, signal transmission between adjacent first electromagnetic induction portions 211 can be facilitated. Moreover, the first electromagnetic induction portion 211 can have a larger sensing area, thereby improving the accuracy of electromagnetic touch.

[0088] In one embodiment, the second electromagnetic electrode 220 includes a plurality of second electromagnetic induction parts 222 and a plurality of second electromagnetic connection parts 223 alternately arranged in the second direction, the two ends of a second electromagnetic connection part 223 are respectively connected to two second electromagnetic induction parts 222, the second electromagnetic induction parts 222 are arranged corresponding to the second rhombus structure 124, the second electromagnetic induction parts 222 are located inside the corresponding second rhombus structure 124, and are arranged at intervals from the second rhombus structure 124. The second electromagnetic induction parts 222 and the second rhombus structure 124 are arranged correspondingly, which means that the center of the second electromagnetic induction part 222 coincides with the orthographic projection of the center of the second rhombus structure 124 on the substrate 16. In the embodiment of the application, by setting the second electromagnetic connection part 223, signal transmission between adjacent second electromagnetic induction parts 222 can be facilitated. Moreover, the second electromagnetic induction part 222 can have a larger sensing area, thereby improving the accuracy of electromagnetic touch.

[0089] It should be noted that in Fig.14 In the illustrated embodiment, the outer contour of the first electromagnetic induction portion 211 is a rhombus, and the outer contour of the first electromagnetic induction portion 211 is arranged parallel to the first rhombus structure 113. In some embodiments, the outer contour of the first electromagnetic induction portion 211 may be a circle, a rectangle or other shapes, which are not limited here. Fig.14In the illustrated embodiment, the outer contour of the second electromagnetic induction portion 222 is a rhombus, and the outer contour of the second electromagnetic induction portion 222 is arranged in parallel with the second rhombus structure 124. In some embodiments, the outer contour of the second electromagnetic induction portion 222 can be a circle, a rectangle, or other shapes, which are not limited here. It can be understood that the specific implementation method of the capacitor electrode using a rhombus structure is similar to that of the capacitor electrode using the aforementioned strip structure. Regarding the via setting method and connection method in the capacitor electrode using a rhombus structure, please refer to the above definition, which will not be repeated here.

[0090] Fig.15 FIG. 1 is a schematic diagram of a touch panel film layer according to an embodiment of the present invention. Fig.15 In one embodiment, the touch panel further includes a light emitting element layer 14 and a filter layer 15. The touch panel of this embodiment may also be referred to as a touch display panel.

[0091] The light emitting element layer 14 is located between the substrate 16 and the first metal layer 11. The light emitting element layer 14 includes a plurality of light emitting elements 610. The light emitting element 610 may be a liquid crystal light emitting element 610, a plasma light emitting element 610, an organic light emitting diode (OLED) light emitting element 610, an electrowetting light emitting element 610, an electrophoretic light emitting element 610, or an electrochromic light emitting element 610. The light emitting element layer 14 may include a light emitting material layer 14a and an electrode layer 14b which are stacked, and the light emitting material located in the light emitting material layer 14a and the electrode material at the corresponding position in the electrode layer 14b together form the light emitting element 610.

[0092] The filter layer 15 is located on the side of the second metal layer 13 away from the insulating layer 12, and the filter layer 15 includes a plurality of filter structures 15 of different colors corresponding to the light-emitting element 610. In addition, adjacent filter structures 15 are separated by black matrices 15. The setting method of the filter layer 15 adopted in this embodiment can be called COE (Color Filter On TFE) technology. The filter layer 15 formed by the COE technology can ensure the efficient transmission of the display light reflected by the OLED material, and effectively absorb other wavelengths of light in the ambient light that are not the corresponding primary colors, thereby achieving efficient absorption of ambient light and purification of display light. Compared with the polarizer and color filter in the related art, the COE technology not only improves the transmittance and reduces power consumption, but also makes the touch display panel brighter and clearer.

[0093] Fig.16 is a schematic diagram of a light emitting element 610 and an electromagnetic induction electrode 200 according to an embodiment, Fig.16, the orthographic projection of the light emitting element 610 on the substrate 16 is staggered with the orthographic projection of the electromagnetic induction electrode 200 on the substrate 16. Based on the corresponding relationship between the light emitting element 610 and the filter structure 15, the orthographic projection of the electromagnetic induction electrode 200 on the substrate 16 can completely fall within the orthographic projection of the black matrix 15 on the substrate 16, thereby reducing the shielding of the electromagnetic induction electrode 200 on the light emitting path of the light emitting element 610, and improving the display quality of the touch display panel. Fig.17 FIG. 1 is a partial schematic diagram of an electromagnetic touch electrode in a display panel according to an embodiment of the present invention. Fig.17 In some cases, the arrangement of the electromagnetic touch electrodes may be adjusted, for example, by reducing the arrangement density of the electromagnetic touch electrodes in the middle region of the figure, so as to reserve space in the first metal layer for arranging the first bridge structure.

[0094] Continue to refer Fig.14 In one embodiment, the metal grid includes a plurality of first routing lines extending along a third direction and a plurality of second routing lines extending along a fourth direction, wherein the first direction, the second direction, the third direction and the fourth direction are different from each other. Fig.14 The metal mesh of the winding mesh routing is shown by taking the first electromagnetic electrode 210 as an example. The winding mesh routing can avoid the light-emitting devices in the light-emitting element layer 14, reduce the shielding of the metal grid on the light-emitting path of the light-emitting devices, improve the light intensity, and ensure the display quality.

[0095] In one embodiment, both the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 include a metal grid, and the arrangement density of the metal grid of the capacitive sensing electrode 100 is lower than the arrangement density of the metal grid of the electromagnetic induction electrode 200. Specifically, the capacitive sensing electrode 100 with a lower arrangement density of the metal grid can reduce the influence of the capacitive sensing electrode 100 on the light emission of the light-emitting element layer 14, thereby ensuring the display quality. However, the electromagnetic induction electrode 200 has a higher impedance requirement than the capacitive sensing electrode 100, that is, it needs to have a lower impedance. Therefore, increasing the arrangement density of the metal grid of the electromagnetic induction electrode 200 can reduce the impedance of the electromagnetic induction electrode 200, further improving the effectiveness and accuracy of electromagnetic touch. Moreover, since the electromagnetic induction electrode 200 is shielded by the black matrix 15, increasing the arrangement density of the metal grid of the electromagnetic induction electrode 200 will not cause visibility problems.

[0096] The present application also provides a touch panel, which includes a capacitive sensing electrode 100 and an electromagnetic sensing electrode 200. Fig.13 The capacitance sensing electrode 100 includes a plurality of first capacitance electrodes 110 extending along a first direction and a plurality of second capacitance electrodes 120 extending along a second direction.

[0097] The first direction and the second direction are different, and the first direction can be perpendicular to the second direction. For example, the first direction is horizontal, and the second direction is vertical. For another example, the first direction is vertical, and the second direction is horizontal. The horizontal direction can be understood as the direction from the first side of the touch device to the second side, and the vertical direction can be understood as the direction from the top side of the touch device to the bottom side. For ease of explanation, the following embodiments are all described by taking the first direction as horizontal and the second direction as vertical as an example.

[0098] One of the first capacitor electrode 110 and the second capacitor electrode 120 is a capacitor transmitting electrode, and the other is a capacitor receiving electrode. For example, the first capacitor electrode 110 is a capacitor transmitting electrode, and the second capacitor electrode 120 is a capacitor receiving electrode. For another example, the first capacitor electrode 110 is a capacitor receiving electrode, and the second capacitor electrode 120 is a capacitor transmitting electrode. When a finger or a capacitive active pen touches or approaches the touch panel, a coupling capacitor is formed with the surface of the touch panel, thereby causing a slight change in the current to characterize the touch operation of the finger or the capacitive active pen. Specifically, the capacitor transmitting electrode sends a capacitive excitation signal in turn, and a plurality of capacitor receiving electrodes simultaneously receive the capacitive touch signal, so that the capacitance value of the intersection point of the capacitor transmitting electrode and each capacitor receiving electrode can be obtained. After completing the scanning of each capacitor transmitting electrode, the coordinates of one or more touch points can be calculated based on the two-dimensional capacitance value data of the touch panel. For ease of explanation, the subsequent embodiments are all described by taking the first capacitor electrode 110 as a capacitor transmitting electrode and the second capacitor electrode 120 as a capacitor receiving electrode as an example.

[0099] Furthermore, the first capacitor electrode 110 and the second capacitor electrode 120 are both connected to the touch chip. In the case where the touch panel further integrates a display function, the touch chip can be integrated with the display driver chip (Display Driver Integrated Circuit, DDIC) to form a touch display chip (Touch and Display Driver Integrated Circuit, TDIC). The capacitor transmitting electrode can send a capacitor excitation signal under the control of the touch chip, and the capacitor receiving electrode transmits the received capacitor touch signal to the touch chip so that the touch chip obtains the coordinates of the touch point. Among them, the touch chip can be set close to the bottom edge of the touch device. The first capacitor electrode 110 extending in the horizontal direction can be partially connected to the touch chip by the end close to the first side, and the other part can be connected to the touch chip by the end close to the second side. The number of the first capacitor electrodes 110 in the above two parts can be the same or similar to balance the number of touch lines on the left and right sides and reduce the width of the screen frame 22. The second capacitor electrode 120 extending in the longitudinal direction is connected to the touch chip at an end portion close to the bottom edge, so as to shorten the length of the touch wiring between the second capacitor electrode 120 and the touch chip.

[0100] The electromagnetic induction electrode 200 includes a plurality of first electromagnetic electrodes 210 and a plurality of second electromagnetic electrodes 220, and the electromagnetic induction electrode 200 is arranged at intervals from the capacitive sensing electrode 100. The electromagnetic electrode may also be referred to as an electromagnetic coil. One of the first electromagnetic electrode 210 and the second electromagnetic electrode 220 is an electromagnetic transmitting electrode, and the other is an electromagnetic receiving electrode. For example, the first electromagnetic electrode 210 is an electromagnetic transmitting electrode, and the second electromagnetic electrode 220 is an electromagnetic receiving electrode. For another example, the first electromagnetic electrode 210 is an electromagnetic receiving electrode, and the second electromagnetic electrode 220 is an electromagnetic transmitting electrode. The electromagnetic transmitting electrode is used to send electromagnetic waves to the electromagnetic pen. When the electromagnetic pen with a resonant circuit moves on the screen provided with an electromagnetic induction layer, the resonant circuit is excited by the electromagnetic excitation signal emitted by the electromagnetic transmitting electrode, and emits a resonant signal as an electromagnetic touch signal. The electromagnetic receiving electrode is used to receive the electromagnetic touch signal generated after the electromagnetic pen resonates with the electromagnetic wave sent by the electromagnetic transmitting electrode, thereby determining the position of the electromagnetic pen on the screen. For the convenience of description, the following embodiments are described by taking the first electromagnetic electrode 210 as the electromagnetic transmitting electrode and the second electromagnetic electrode 220 as the electromagnetic receiving electrode as an example.

[0101] Among them, at least part of the electromagnetic induction electrodes 200 are arranged in the same layer as the capacitive sensing electrodes 100. Specifically, multiple electromagnetic transmitting electrodes in the electromagnetic induction electrodes 200 may be arranged in the same layer and spaced apart from the capacitive sensing electrodes 100, or multiple electromagnetic receiving electrodes in the electromagnetic induction electrodes 200 may be arranged in the same layer and spaced apart from the capacitive sensing electrodes 100, or multiple electromagnetic transmitting electrodes and multiple electromagnetic receiving electrodes in the electromagnetic induction electrodes 200 may be arranged in the same layer and spaced apart from the capacitive sensing electrodes 100, which is not limited in this embodiment. By arranging at least part of the electromagnetic induction electrodes 200 in the same layer as the capacitive sensing electrodes 100, the number of film layers required to be arranged in the touch panel can be reduced, thereby facilitating the miniaturization and thinness of the touch panel.

[0102] Fig.18 for Fig.13 The second structural diagram of a touch unit in the embodiment, see Fig.18, the first electromagnetic electrode 210 is located between the adjacent first capacitor electrode 110 and the second capacitor electrode 120, and the second electromagnetic electrode 220 is located between the adjacent first capacitor electrode 110 and the second capacitor electrode 120. Specifically, by locating the electromagnetic induction electrode 200 between the adjacent first capacitor electrode 110 and the second capacitor electrode 120, the space within the layer can be fully utilized, and the problem of excessive gap between electrodes caused by the mutual avoidance of the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 can be reduced, so that the electrode area of ​​the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 can be increased, so as to improve the sensitivity and accuracy of touch sensing through electrodes with larger areas. Moreover, the setting method of this embodiment can make the capacitive sensing electrode 100 and the electromagnetic induction electrode 200 arranged in a more regular manner. The regular arrangement method can not only make the electrode arrangement method in each touch control unit the same, but also facilitate the data processing of the touch control chip. The regular arrangement can also make the absorption and reflection capabilities of the light beam at various locations on the touch panel similar, thereby reducing the uneven reflection caused by the uneven arrangement of the sensing electrodes in the touch panel, thereby improving the display uniformity of the touch device.

[0103] In one embodiment, the first capacitor electrode 110 includes a plurality of first diamond structures 113 arranged in a first direction and connected to each other, and the second capacitor electrode 120 includes a plurality of second diamond structures 124 arranged in a second direction and connected to each other. The centers of the first diamond structures 113 are arranged in an array, the centers of the second diamond structures 124 are arranged in an array, and the connection points of the first diamond structures 113 and the connection points of the second diamond structures 124 are arranged correspondingly. The connection points of the first diamond structures 113 and the connection points of the second diamond structures 124 are arranged correspondingly, which means that the center of the connection point of the first diamond structure 113 and the center of the connection point of the second diamond structure 124 coincide with the orthographic projection on the substrate 16. In the embodiment of the application, by adopting a diamond-shaped capacitor electrode, it is easier to be compatible with the solutions in the related art, thereby reducing the cost of modifying the shape of the capacitor sensing electrode 100.

[0104] Continue to refer Fig.15In one embodiment, the touch panel is stacked with a first metal layer 11, an insulating layer 12 and a second metal layer 13. Among them, the insulating layer 12 can be made of an insulating material, for example, an inorganic material. Exemplarily, the insulating layer 12 can be made of at least one of Al2O3, TiO2, SiNx, SiCNx, SiOx, etc. to ensure the insulating effect of the insulating layer 12 and increase the water blocking function of the insulating layer 12. At least one of the first metal layer 11 and the second metal layer 13 can be made of a metal mesh. The metal mesh is a mesh structure made of metal wire or metal foil. The metal mesh has a high transparency, so it has little effect on the display effect of the touch device and does not affect the user's viewing experience. Moreover, the metal mesh has the characteristics of excellent conductivity, bendability and light weight, so it is suitable for touch devices such as mobile phones that have bending requirements and portability requirements.

[0105] In one embodiment, the touch panel further includes a light emitting element layer 14 and a filter layer 15. The touch panel of this embodiment may also be referred to as a touch display panel.

[0106] The light emitting element layer 14 is located between the substrate 16 and the first metal layer 11. The light emitting element layer 14 includes a plurality of light emitting elements 610. The light emitting element 610 may be a liquid crystal light emitting element 610, a plasma light emitting element 610, an organic light emitting diode (OLED) light emitting element 610, an electrowetting light emitting element 610, an electrophoretic light emitting element 610, or an electrochromic light emitting element 610. The light emitting element layer 14 may include a light emitting material layer 14a and an electrode layer 14b which are stacked, and the light emitting material located in the light emitting material layer 14a and the electrode material at the corresponding position in the electrode layer 14b together form the light emitting element 610.

[0107] The filter layer 15 is located on the side of the second metal layer 13 away from the insulating layer 12, and the filter layer 15 includes a plurality of filter structures 15 of different colors corresponding to the light-emitting element 610. In addition, adjacent filter structures 15 are separated by black matrices 15. The setting method of the filter layer 15 adopted in this embodiment can be called COE (Color Filter On TFE) technology. The filter layer 15 formed by the COE technology can ensure the efficient transmission of the display light reflected by the OLED material, and effectively absorb other wavelengths of light in the ambient light that are not the corresponding primary colors, thereby achieving efficient absorption of ambient light and purification of display light. Compared with the polarizer and color filter in the related art, the COE technology not only improves the transmittance and reduces power consumption, but also makes the touch display panel brighter and clearer.

[0108] In one embodiment, the metal grid includes a plurality of first routing lines extending along a third direction and a plurality of second routing lines extending along a fourth direction.

That is, the metal grid is a winding mesh routing line to avoid the light emitting device in the light emitting element layer 14, reduce the shielding of the light emitting path of the light emitting device by the metal grid, improve the light intensity, and ensure the display quality.

[0109] The embodiment of the present application also provides a touch screen, comprising a cover plate and the touch panel as described above. The cover plate is located on the touch side of the touch panel and covers the touch panel. In this embodiment, by providing the cover plate, the display panel can be protected, and the damage to the display panel caused by external force can be reduced, thereby improving the reliability of the display panel.

In this embodiment, based on the above-mentioned touch screen, a touch device is provided that is applicable to different types of styluses and has good thickness and foldability.

[0111] In one embodiment, the touch device further includes a controller. The controller is connected to the touch screen and is used to control the capacitive sensing electrode 100 to scan the capacitive touch signal in a first time period and to control the electromagnetic sensing electrode 200 to scan the electromagnetic touch signal in a second time period. The first time period and the second time period are two time periods staggered from each other in the same frame.

[0112] Fig.19 FIG. 1 is a timing diagram of capacitive scanning and electromagnetic scanning according to an embodiment of the present invention. Fig.19 , when both the capacitive sensing function and the electromagnetic sensing function of the touch device are turned on, within a frame time, the scanning time of the capacitive touch signal and the scanning time of the electromagnetic touch signal can be staggered to prevent interference between the signals. Furthermore, the scanning time of the capacitive touch signal can be overlapped with the data transmission and processing time of the electromagnetic touch signal, thereby providing more time for scanning the capacitive touch signal, thereby improving the reporting rate of the capacitive touch signal while ensuring the signal-to-noise ratio (SNR) of the electromagnetic touch signal. Specifically, based on different reporting rates, the scanning durations of the capacitive touch signal and the electromagnetic touch signal can be set accordingly. For example, if the reporting rate is 120Hz, the scanning time of a frame is 8.3ms, and the sum of the scanning durations of the capacitive touch signal and the electromagnetic touch signal is less than or equal to 8.3ms. If the reporting rate is 240Hz, the scanning time of a frame is 4.17ms, and the sum of the scanning durations of the capacitive touch signal and the electromagnetic touch signal is less than or equal to 4.17ms.

[0113] Specifically, the touch device can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Fig. 20 The figure is an internal structure diagram of a touch device of an embodiment.
