In existing technical solutions, in order to make a capacitive touch screen compatible with electromagnetic touch operations, electromagnetic touch functional elements are integrated inside the capacitive touch screen. However, due to the too-close distance between the electromagnetic touch functional elements and the elements of the capacitive touch screen, the induction interferes with each other and the load is too large, so the performance needs to be improved.

[0059] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without some of these specific details. The description of the embodiments is merely provided to better understand the present application by showing examples of the present application. In the drawings and the following description, at least some of the well - known structures and technologies are not shown in order to avoid unnecessarily obscuring the present application; and, for clarity, the dimensions of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0060] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover a non - exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "comprising......" do not preclude the presence of additional identical elements in the process, method, article or device comprising the said elements.

[0061] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the touch module and display device of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0062] At present, the touch screen is an input and display device that integrates display function and control function. That is, the light-emitting elements of the display panel are used to display and output the picture, while other control elements are used to facilitate users to directly click on the screen to input information. There are many ways to input touch screens. Among them, users can directly use their fingers to touch, drag and gesture the displayed content. This input method is the simplest and most convenient human-computer interaction method among the current input methods.

[0063] Currently, the mainstream solution for achieving finger touch is to use a capacitive touch screen. Its basic principle is to use capacitance changes to detect the touch position. The capacitive touch screen includes a touch panel and a control circuit. The touch panel forms a capacitive structure by overlapping two layers of conductive materials or electrodes, and completes touch perception, position detection and subsequent data processing through the control circuit.

[0064] The capacitive touch panel is generally a separate module externally mounted on the display panel, and together with the display panel forms a complete display module.

[0065] However, with the continuous development of display technology, people have more and more demands for touch screens. In addition to being able to be touched by fingers, the touch screens also require the use of electromagnetic active pens for touch interaction.

[0066] Electromagnetic touch mainly uses the change in magnetic flux between the electromagnetic active pen and the electromagnetic induction coil to detect the touch position, so the display device needs to be equipped with external components such as electromagnetic induction coils.

[0067] At present, the electromagnetic pen technology or capacitive touch technology of conventional OLED display panels both attach functional components to the backlight side of the display panel. The electromagnetic module components or the capacitive touch panel and the display panel together form a complete display module. This results in a thick display module, which is not conducive to folding and has a low degree of integration.

[0068] In the prior art, the external functional components of the electromagnetic module elements are embedded in the capacitive touch panel. As a result, the electromagnetic module elements are too close to the functional elements in the capacitive touch panel, and the induction between the two interferes with each other, resulting in an excessive load for realizing the electromagnetic touch function and the capacitive touch function.

[0069] In consideration of solving the above problems and technical requirements, the present application proposes a touch module.

[0070] To better understand the present application, the following Figures 1 to 10 will describe the touch module 100 of the embodiment of the present application in detail.

[0071] Figure 1 FIG. shows a stacked structure of a touch module 100 provided by an embodiment of the present application. Figure 2 FIG. shows a top view structure of a touch module 100 provided by an embodiment of the present application.

[0072] Please refer to Figure 1 and Figure 2 , in a first aspect, an embodiment of the present application provides a touch module 100, including a substrate 10, a touch electrode unit 20, and an electromagnetic coil unit 30.

[0073] The touch electrode unit 20 includes a touch electrode 21. The electromagnetic coil unit 30 includes a first electromagnetic electrode 31 and a second electromagnetic electrode 32. The touch electrode unit 20 and the electromagnetic coil unit 30 are disposed on one side of the substrate 10. The first electromagnetic electrode 31 and the second electromagnetic electrode 32 are disposed in a different layer from the touch electrode 21, or the touch electrode 21 is disposed in the same layer as at least one of the first electromagnetic electrode 31 and the second electromagnetic electrode 32. The orthographic projection of the touch electrode unit 20 on the substrate 10 is staggeredly disposed from the orthographic projection of the electromagnetic coil unit 30 on the substrate 10.

[0074] In the touch module 100 provided by the embodiment of the present application, by disposing the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in a different layer from the touch electrode or at least one of them in the same layer as the touch electrode 21, while integrating the touch electrode unit 20 and the electromagnetic coil unit 30 into a touch module 100, by staggeredly disposing the orthographic projections of the touch electrode unit 20 and the electromagnetic coil unit 30 on the substrate 10, the distance between the touch electrode unit 20 and the electromagnetic coil unit 30 is increased, and the coupling capacitance between the touch electrode unit 20 and the electromagnetic coil unit 30 is reduced, thereby effectively reducing the load of the touch module 100 and ultimately improving the performance of the touch module 100.

[0075] In the touch module 100, the substrate 10 mainly plays a role of supporting and carrying, and other film layers are stacked on the substrate 10. The so-called stacking setting mentioned here means that: after one, two or more of the same layers in the horizontal plane perpendicular to the thickness direction Z of the other film layers, they are then stacked in the thickness direction Z of the substrate 10. The substrate 10 may include multiple film layer structures, and the substrate 10 may include, but is not limited to, film layer structures such as a protective film layer structure, an insulating film layer structure, and a coil structure. For the specific film layer structure and the composition of the film layer structure of the substrate 10, the embodiments of the present application do not make any limitations. And the thickness direction Z of the other film layers on one side of the substrate 10 is usually the same as the thickness direction Z of the substrate 10 itself. Therefore, for the convenience of description, the thickness direction Z of the substrate 10 or the thickness direction Z of the other film layers mentioned in the subsequent embodiments of the present application are all shown in the same direction.

[0076] It should be noted that Figure 1 The structure shown only briefly shows the stacking relationship of the touch module 100 along the thickness direction Z, and is used to illustrate the relative position relationship of the touch electrode 21, the first electromagnetic electrode 31, and the second electromagnetic electrode 32 along the thickness direction Z. The mutual occlusion and overlapping relationship of each film layer and structure in the touch module 100 in the plane direction Figure 1 is not shown in detail.

[0077] The touch electrode unit 20 is used to implement the capacitive touch function. Capacitive touch is a control method for users to control the display content when touching the touch module 100 of the display panel with their fingers. Capacitive touch includes two methods: self-capacitive touch and mutual-capacitive touch. Therefore, there are also two different structures for the touch electrode unit 20 that realizes capacitive touch.

[0078] Among them, the touch electrode unit 20 that realizes self-capacitive touch includes at least one touch electrode 21. The touch electrode 21 forms a capacitor with the ground. When a finger touches the touch module 100, the capacitance of the finger will be superimposed on the screen capacitance, increasing the screen capacitance so as to detect the capacitance change and detect the touch position.

[0079] At this time, the touch electrode unit 20 may only include one touch electrode 21, and the touch electrode 21 is arranged in a different layer from the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the touch module 100.

[0080] At the same time, the touch electrode unit 20 that realizes mutual-capacitive touch includes at least two touch electrodes 21. A capacitor is formed between the two touch electrodes 21 by themselves. When a finger touches the touch module 100, the capacitance of the finger will be superimposed on the capacitor formed between the two electrodes, increasing the capacitance between a certain two electrodes so as to detect the capacitance change and detect the touch position.

[0081] Therefore, the touch electrode unit 20 includes at least two types of touch electrodes 21. The touch electrodes 21 can be arranged such that both types of touch electrodes 21 are arranged in a different layer from the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the touch module 100, or one type of touch electrode 21 can be arranged in a different layer from the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the touch module 100, and the other type of touch electrode 21 can be arranged in the same layer as at least one of the first electromagnetic electrode 31 and the second electromagnetic electrode 32.

[0082] Exemplarily, in a general setting manner, whether a self-capacitive touch scheme or a mutual-capacitive touch scheme is adopted, the touch electrode unit 20 includes a horizontal electrode array and a vertical electrode array.

[0083] The embodiments of the present application do not limit the types and setting manners of the touch electrode unit 20, and at least include the above three setting manners.

[0084] Exemplarily, the materials of the touch electrodes 21 include copper (Cu), silver (Ag), aluminum (Al), molybdenum (Mo), etc., and can also be alloy materials, such as titanium-aluminum alloy (TiALTi), copper-nickel alloy (CuNi), aluminum-molybdenum alloy (MoAlMo), etc. The embodiments of the present application do not limit this.

[0085] Similarly, the electromagnetic coil unit 30 covers the touch module 100 by arranging two electromagnetic electrodes in different directions, and detects the contact position of the electromagnetic active pen by detecting the change in the magnetic flux of the electromagnetic electrodes.

[0086] Exemplarily, in a general setting manner, the first electromagnetic electrodes 31 are arranged side by side in the second direction Y, and the second electromagnetic electrodes 32 are arranged side by side in the first direction X.

[0087] The first electromagnetic electrode 31 and the second electromagnetic electrode 32 can be arranged in a staggered layer. Here, "staggered layer arrangement" should be understood as that the two electromagnetic electrodes extending along two intersecting directions are insulated from each other to prevent the two coils from overlapping and forming a short circuit.

[0088] The first electromagnetic electrode 31 and the second electromagnetic electrode 32 can also be arranged in the same layer. Here, "same layer arrangement" should be understood as that the two electromagnetic electrodes extending along two intersecting directions are arranged in the same layer. The overlapping position of the orthographic projections of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 on the substrate 10 needs to be disconnected to avoid a short circuit. It can be arranged such that the first electromagnetic electrode 31 is disconnected and a connection structure is arranged in other structural layers to conduct the disconnected part of the first electromagnetic electrode 31, or it can be arranged such that the second electromagnetic electrode 32 is disconnected and a connection structure is arranged in other structural layers to conduct the disconnected part of the second electromagnetic electrode 32.

[0089] The embodiments of the present application do not limit the types and arrangement manners of the electromagnetic coil unit 30, and at least include the above three arrangement manners.

[0090] The electromagnetic coil unit 30 may further include a first overlapping portion 311, and a plurality of first electromagnetic electrodes 31 arranged side by side in the second direction Y are connected by the first overlapping portion 311 to form a toothed arrangement. Here, the "toothed arrangement" means that two first electromagnetic electrodes 31 are connected into a path through the first overlapping portion 311, the end of one first electromagnetic electrode 31 is connected to the first electromagnetic electrode 31 in the next row, and the first electromagnetic electrodes 31 in the next row in multiple groups of two first electromagnetic electrodes 31 connected by the first overlapping portion 311 are connected to the same driving circuit 33.

[0091] Exemplarily, in the embodiments of the present application, the driving circuit 33 is arranged at a position on the same side as the first overlapping portion 311. It can be understood that the driving circuit 33 may also be arranged at a position on the other side opposite to the first overlapping portion 311. For the convenience of description and clear illustration in the embodiments of the present application, the manner of arranging the first overlapping portion 311 and the driving circuit 33 on the same side is selected, and the arrangement manners of the driving circuit 33 and the first overlapping portion 311 are not limited.

[0092] Similarly, a plurality of second electromagnetic electrodes 32 arranged side by side in the first direction X are connected by a second overlapping portion 321 to form a toothed distribution.

[0093] It can be understood that in the embodiments of the present application, only for the convenience of description, the first direction X and the second direction Y are defined, but actually no limitation is made thereto.

[0094] Exemplarily, the materials of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 include copper (Cu), silver (Ag), aluminum (Al), molybdenum (Mo), etc., and may also be alloy materials, such as titanium aluminum alloy (TiALTi), copper nickel alloy (CuNi), aluminum molybdenum alloy (MoAlMo), etc. The embodiments of the present application do not limit this.

[0095] The orthographic projections of the touch electrode unit 20 and the electromagnetic coil unit 30 on the substrate 10 are staggeredly arranged. The "staggered arrangement" should be understood as that the preset distance between the centers of the orthographic projections of the touch electrode unit 20 and the electromagnetic coil unit 30 on the substrate 10 is greater than 0. The arrangement manner may include the arrangement manner in which the orthographic projections of the touch electrode unit 20 and the electromagnetic coil unit 30 on the substrate 10 do not overlap completely, and may also include the arrangement manner in which the centers of the orthographic projections of the touch electrode unit 20 and the electromagnetic coil unit 30 on the substrate 10 are at least staggeredly arranged, rather than the manner of staggering the entire structures of the touch electrode unit 20 and the electromagnetic electrode unit, and the effect of reducing the load can also be achieved. The embodiments of the present application do not limit this.

[0096] The touch electrode unit 20 and the electromagnetic coil unit 30 are arranged with their orthographic projections on the substrate 10 staggered. Compared with the way of laminating the touch electrode unit 20 and the electromagnetic coil unit 30, the distance between the touch electrode unit 20 and the electromagnetic coil unit 30 is increased. Further, the coupling capacitance between the touch electrode unit 20 and the electromagnetic coil unit 30 is reduced, thereby effectively reducing the load of the touch module 100 and ultimately improving the performance of the touch module 100.

[0097] In some embodiments, the touch electrode 21 includes a first touch electrode 22 and a second touch electrode 23, and at least two of the first touch electrode 22, the second touch electrode 23, the first electromagnetic electrode 31, and the second electromagnetic electrode 32 are arranged on the same layer.

[0100] In these optional embodiments, for the touch module 100 provided by the embodiments of the present application, by arranging the first touch electrode 22 and the second touch electrode 23 on the same layer, while reducing the thickness of the touch module 100, the touch electrode unit 20 in the touch module 100 can utilize the existing capacitive touch structure, further reducing the cost of the touch module 100.

[0101] Figure 7 Fig. shows another stacked structure of the touch module 100 provided by the embodiments of the present application. Figure 8 Fig. shows another top view structure of the touch module 100 provided by the embodiments of the present application.

[0102] Please refer to Figure 7 and Figure 8 , in some optional embodiments, one of the first touch electrode 22 and the second touch electrode 23 is arranged on the same layer as one of the first electromagnetic electrode 31 and the second electromagnetic electrode 32.

[0103] In these alternative embodiments, the touch module 100 provided by the embodiments of the present application, by arranging one of the first touch electrode 22 and the second touch electrode 23 in the touch electrode unit 20 and one of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the electromagnetic coil unit 30 on the same layer, can reduce the thickness of the touch module 100 while increasing the distance between the first touch electrode 22 and the second touch electrode 23 in the touch electrode unit 20 and the distance between the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the electromagnetic coil unit 30, thereby reducing the capacitance inside the touch electrode unit 20 and the electromagnetic coil unit 30, and respectively effectively improving the sensitivity of the touch electrode unit 20 and the electromagnetic coil unit 30 in the touch module 100, so as to overall improve the performance of the touch module 100.

[0104] It should be noted that Figure 7 The shown structure only briefly shows the stacking relationship of the touch module 100 along the thickness direction Z, and is used to illustrate the relative positional relationship of the touch electrode 21, the first electromagnetic electrode 31 and the second electromagnetic electrode 32 along the thickness direction Z. The mutual occlusion and overlapping relationship of each film layer and structure in the touch module 100 in the planar direction is Figure 1 not shown in detail.

[0105] Please continue to refer to Figure 7 and Figure 8 , in some alternative embodiments, the first touch electrode 22 is arranged on the same layer as the first electromagnetic electrode 31.

[0106] In these alternative embodiments, the touch module 100 provided by the embodiments of the present application, by arranging the first touch electrode 22 on the same layer as the first electromagnetic electrode 31, while reducing the thickness of the touch module 100, arranges the first touch electrode 22 and the first electromagnetic electrode 31 on the corresponding same layer, reducing the preparation of additional connection structures and further reducing the cost of the touch module 100.

[0107] , optionally, the second touch electrode 23 is arranged on the same layer as the second electromagnetic electrode 32.

[0108] Figure 9 shows another stacking structure of the touch module 100 provided by the embodiments of the present application, Figure 10 shows another top view structure of the touch module 100 provided by the embodiments of the present application.

[0109] Please refer to Figure 9 and Figure 10 , in some alternative embodiments, the first touch electrode 22 is arranged on the same layer as one of the first electromagnetic electrode 31 and the second electromagnetic electrode 32, and the second touch electrode 23 is arranged on the same layer as the other of the first electromagnetic electrode 31 and the second electromagnetic electrode 32.

[0110] In these alternative embodiments, for the touch control module 100 provided in the embodiments of the present application, by disposing the first touch electrode 22 and the second touch electrode 23 corresponding to at least one of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the electromagnetic coil unit 30 respectively, and by disposing two layers of electrodes arranged in the same layer, the thickness of the touch control module 100 is further reduced.

[0111] It should be noted that Figure 9 The structure shown only briefly shows the stacking relationship of the touch control module 100 along the thickness direction Z, and is used to illustrate the relative positional relationship of the touch electrode 21, the first electromagnetic electrode 31 and the second electromagnetic electrode 32 along the thickness direction Z. The mutual shielding and overlapping relationships of each film layer and structure in the touch control module 100 in the plane direction are not Figure 1 shown in detail.

[0112] Please continue to refer to Figure 9 and Figure 10 , in some alternative embodiments, the first touch electrode 22 and the first electromagnetic electrode 31 are arranged in the same layer, and the second touch electrode 23 and the second electromagnetic electrode 32 are arranged in the same layer.

[0113] In these alternative embodiments, for the touch control module 100 provided in the embodiments of the present application, by arranging the first touch electrode 22 and the first electromagnetic electrode 31 in the same layer, and the second touch electrode 23 and the second electromagnetic electrode 32 corresponding to each other in the same layer, while further reducing the thickness of the touch control module 100, the preparation of additional connection structures is reduced, thereby further reducing the cost of the touch control module 100.

[0114] Please refer to Figure 2 , in some embodiments, the first touch electrode 22 and the second touch electrode 23 include a plurality of first functional sub-blocks 211, the first electromagnetic electrode 31 and the second electromagnetic electrode 32 include a plurality of second functional sub-blocks 301, and the orthographic projections of the first functional sub-blocks 211 on the substrate 10 and the orthographic projections of the second functional sub-blocks 301 on the substrate 10 are arranged at intervals.

[0115] In these alternative embodiments, for the touch control module 100 provided in the embodiments of the present application, by staggering the orthographic projections of the first functional sub-blocks 211 and the second functional sub-blocks 301 on the substrate 10, the distance between the first functional sub-blocks 211 and the second functional sub-blocks 301 is increased, the coupling capacitance between the first functional sub-blocks 211 and the second functional sub-blocks 301 is reduced, thereby effectively reducing the load of the touch control module 100 and improving the performance of the touch control module 100.

[0116] The electrode shapes of the first touch electrode 22 and the second touch electrode 23 in the touch electrode unit 20 that play the main functions are both block-shaped. Exemplarily, the electrode shapes of the first touch electrode 22 and the second touch electrode 23 can be diamond-shaped or square-shaped, which are not limited in the embodiments of the present application.

[0117] "Spaced apart" should be understood as that the distance between the boundaries of the positive projections of the first functional sub-block 211 and the second functional sub-block 301 on the substrate 10 is greater than or equal to 0, and there is no overlapping part between the positive projections of the first functional sub-block 211 and the second functional sub-block 301 on the substrate 10.

[0118] Therefore, in the touch electrode unit 20, the positive projection of the first functional sub-block 211, which is set as a block for the first touch electrode 22 and the second touch electrode 23, and the structure of the electromagnetic coil unit 30 are spaced apart on the substrate 10, which can reduce the load of the first functional sub-block 211 that plays the main function.

[0119] The electrode shapes of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the electromagnetic coil unit 30 that play the main functions are generally strip-shaped or coil-shaped in the general setting method. However, in the embodiments of the present application, the first electromagnetic electrode 31 and the second electromagnetic electrode 32 are formed by connecting a plurality of second functional sub-blocks 301 with a block shape through other structures.

[0120] Therefore, in the electromagnetic coil unit 30, the positive projection of the second functional sub-block 301, which is set as a block for the first electromagnetic electrode 31 and the second electromagnetic electrode 32, and the positive projection of the first functional sub-block 211 of the touch electrode unit 20 are spaced apart on the substrate 10, which can reduce the load of the second functional sub-block 301 that plays the main function.

[0121] Furthermore, staggering the positive projections of the first functional sub-block 211 and the second functional sub-block 301 on the substrate 10 can also effectively reduce the load and improve the performance of the touch module 100.

[0122] Figure 3 Shows Figure 2 the enlarged structure of area A in

[0123] Please continue to refer to Figure 2 and Figure 3, in some embodiments, the first touch electrode 22, the second touch electrode 23, the first electromagnetic electrode 31, and the second electromagnetic electrode 32 are in a grid trace structure. The first touch electrode 22 and the second touch electrode 23 further include a plurality of first conductive portions 212. The electrically connected ends of the first conductive portions 212 are divided into first functional sub-blocks 211. The grid trace density of the first functional sub-blocks 211 is greater than that of the first conductive portions 212. The orthographic projection of the first conductive portions 212 on the substrate 10 at least partially overlaps with the orthographic projection of the second functional sub-block 301 on the substrate 10.

[0124] In these embodiments, for the touch module 100 provided by the embodiments of the present application, by providing the first conductive portions 212 with a smaller grid trace density at the overlapping portions of the first touch electrode 22 and the second touch electrode 23 with the orthographic projection of the second functional sub-block 301 on the substrate 10 to connect the first functional sub-blocks 211, while ensuring the normal electrical connection of the first touch electrode 22 and the second touch electrode 23 of the touch electrode unit 20, the coupling capacitance between the touch electrode unit 20 and the electromagnetic coil unit 30 is further reduced, the load of the touch module 100 is further effectively reduced, and finally the performance of the touch module 100 is further improved.

[0125] The grid trace structure should be understood as that when fabricating the electrode structures of the touch electrode unit 20 and the electromagnetic coil unit 30 on the entire substrate 10, a layer of entire-surface metal grid traces is interrupted. The gaps between the entire-surface metal grids can accommodate the light-emitting structures of the pixels and do not affect the normal light-emitting function of the display panel. The grid trace structure formed by interrupting the entire-surface grid traces and insulatingly arranging multiple spaced-apart portions constitutes the first touch electrode 22, the second touch electrode 23, the first electromagnetic electrode 31, the second electromagnetic electrode 32, and the first conductive portions 212, etc.

[0126] And between the first functional sub-blocks 211, a connection structure is required to electrically connect some of the first functional sub-blocks 211 on the same layer. Since the orthographic projections of the first functional sub-blocks 211 and the second functional sub-block 301 on the substrate 10 are staggeredly arranged, the connection structure will at least partially overlap with the orthographic projection of the second functional sub-block 301 on the substrate 10.

[0127] By providing the first conductive portions 212 with a grid trace density smaller than that of the first functional sub-blocks 211, the electrical connection requirements of some of the first functional sub-blocks 211 can be met, and at the same time, the load of the touch module 100 can be further reduced, and the performance of the touch module 100 can be improved.

[0128] Please continue to refer to Figure 3 , in some optional embodiments, adjacent first functional sub-blocks 211 are electrically connected by a plurality of first conductive portions 212.

[0129] In these alternative embodiments, the touch module 100 provided by the embodiments of the present application ensures the electrical connection reliability between adjacent two first functional sub-blocks 211 by providing a plurality of first conductive parts 212.

[0130] Exemplarily, the embodiments of the present application set the first conductive part 212 as a plurality of long strip-shaped patterns with a relatively narrow width. While ensuring the electrical connection reliability, the overlapping area of the first conductive part 212 and the second functional sub-block 301 in the orthographic projection on the substrate 10 is further reduced, which can further reduce the load and improve the performance.

[0131] It can be understood that the first conductive part 212 can also be set as a long strip-shaped pattern with a relatively wide width and a further reduced grid trace density, which can also ensure the electrical connection reliability and further reduce the load and improve the performance.

[0132] Please continue to refer to Figure 3 In some alternative embodiments, the first conductive part 212 includes a first connection end 2121 and a second connection end 2122. The plurality of first connection ends 2121 of the plurality of first conductive parts 212 are arranged on the first edge 2111 of a first functional sub-block 211, and the plurality of second connection ends 2122 of the plurality of first conductive parts 212 are arranged on the second edge 2112 opposite to the adjacent first functional sub-block 211.

[0133] In these alternative embodiments, the touch module 100 provided by the embodiments of the present application further reduces the connection line length of the first conductive part 212 by arranging the first connection end 2121 and the second connection end 2122 of the first conductive part 212 on the first edge 2111 and the second edge 2112 opposite to two adjacent first functional sub-blocks 211. While ensuring the electrical connection reliability, the overlapping area of the first conductive part 212 and the second functional sub-block 301 in the orthographic projection on the substrate 10 is further reduced, which can further reduce the load and improve the performance.

[0134] Figure 4 Shows Figure 2 The enlarged structure of area B in

[0135] Please refer to Figure 2 and Figure 4 In some alternative embodiments, the first electromagnetic electrode 31 and the second electromagnetic electrode 32 further include a plurality of second conductive parts 302. The electrical connection ends of the second conductive parts 302 are connected to the second functional sub-block 301. The grid trace density of the first functional sub-block 211 is greater than that of the second conductive parts 302. The orthographic projection of the second conductive parts 302 on the substrate 10 at least partially overlaps with the orthographic projection of the first functional sub-block 211 on the substrate 10.

[0136] In these alternative embodiments, for the touch control module 100 provided in the embodiments of the present application, by setting the grid trace density to be less than the second conductive portion 302 of the second functional sub-block 301, the electrical connection requirements of some of the second functional sub-blocks 301 can be met. At the same time, the load of the touch control module 100 can be further reduced, and the performance of the touch control module 100 can be improved.

[0137] The specific setting manner of the second conductive portion 302 is the same as that of the first conductive portion 212, and will not be elaborated here.

[0138] Please continue to refer to Figure 4 , in some alternative embodiments, the second functional sub-blocks 301 are electrically connected through a plurality of second conductive portions 302.

[0139] In these alternative embodiments, for the touch control module 100 provided in the embodiments of the present application, by providing a plurality of second conductive portions 302, the electrical connection reliability between two adjacent second functional sub-blocks 301 is ensured.

[0140] The specific graphic shape and setting manner of the second conductive portion 302 are the same as those of the first conductive portion 212, and will not be elaborated here.

[0141] Please continue to refer to Figure 4 , in some alternative embodiments, the second conductive portion 302 includes a third connection end 3021 and a fourth connection end 3022. The plurality of third connection ends 3021 of the plurality of second conductive portions 302 are provided on the third edge 3011 of one second functional sub-block 301, and the plurality of fourth connection ends 3022 of the plurality of second conductive cloths are provided on the fourth edge 3012 of the adjacent second functional sub-block 301 that is oppositely arranged.

[0142] In these alternative embodiments, for the touch control module 100 provided in the embodiments of the present application, by setting the third connection end 3021 and the fourth connection end 3022 of the second conductive portion 302 on the third edge 3011 and the fourth edge 3012 that are oppositely arranged on two adjacent second functional sub-blocks 301, the connection line length of the second conductive portion 302 is further reduced. While ensuring the electrical connection reliability, the overlapping area of the second conductive portion 302 and the first functional sub-block 211 in the orthographic projection on the substrate 10 is further reduced, and the load can be further reduced and the performance can be improved.

[0143] Figure 5 Fig. shows another top view structure of the touch control module 100 provided in the embodiments of the present application.

[0144] Please refer to Figure 5, in some embodiments, the first touch electrode 22, the second touch electrode 23, the first electromagnetic electrode 31, and the second electromagnetic electrode 32 are in a grid trace structure. The first electromagnetic electrode 31 and the second electromagnetic electrode 32 further include a plurality of extension portions 303. The extension portions 303 are electrically connected to some of the second functional sub-blocks 301. The grid trace density of the extension portions 303 is the same as that of the second functional sub-blocks 301. The orthographic projection of the extension portions 303 on the substrate 10 overlaps at least partially with the orthographic projection of the second functional sub-blocks 301 on the substrate 10.

[0145] In these embodiments, for the touch module 100 provided by the embodiments of the present application, by arranging the extension portions 303 to electrically connect some of the second functional sub-blocks 301, and not overlapping the extension portions 303 with the structures other than the second functional sub-blocks 301 of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 in the orthographic projection on the substrate 10, the extension portions 303 only overlap with the orthographic projection of the second functional sub-blocks 301 arranged in a different layer on the substrate 10. While reducing the resistance of the first electromagnetic electrode 31 and the second electromagnetic electrode 32 to reduce the load, no additional load is added, thereby improving the performance of the touch module 100.

[0146] In some alternative embodiments, the extension portions 303 are arranged in the same layer as the first electromagnetic electrode 31 or the second electromagnetic electrode 32. Adjacent second functional sub-blocks 301 are electrically connected through the extension portions 303.

[0148] In some alternative embodiments, the extension portions 303 are arranged in the same layer as the first electromagnetic electrode 31. The orthographic projection of the extension portions 303 on the substrate 10 overlaps at least partially with the orthographic projection of the second functional sub-blocks 301 of the second electromagnetic electrode 32 on the substrate 10.

While reducing the resistance of the first electromagnetic electrode 31 to reduce the load, no additional load between the extension portions 303 and the second electromagnetic electrode 32 is added, thereby further improving the performance of the touch module 100.

[0150] Please refer to Figure 2 , in some embodiments, the first touch electrode 22 and the second touch electrode 23 further include a plurality of cross-bridge portions 213. The cross-bridge portions 213 are arranged in a different layer from the first touch electrode 22 or the second touch electrode 23. The cross-bridge portions 213 are electrically connected between two first functional sub-blocks 211 arranged on the second touch electrode 23. Two first functional sub-blocks 211 of the second touch electrode 23 are arranged in the same layer as one first functional sub-block 211 of the first touch electrode 22, and are arranged on both sides of the first functional sub-block 211 of the first touch electrode 22.

[0160] In these optional embodiments, the touch module 100 provided in the embodiments of the present application protects the electrode structure and other structures of the touch electrode unit 20 and the electromagnetic coil unit 30 from physical scratches or electrochemical corrosion and other accidents by setting a protective layer 50.
