[0039] In the embodiment of the present application, the touch layer 101 is divided into a plurality of touch areas 1011 along a preset direction in the touch module 100, the detection electromagnetic coil 1012 and the plurality of channel electromagnetic coils 1013 are arranged in each touch area 1011, the plurality of channel electromagnetic coils 1013 are arranged in parallel and at intervals along the preset direction, one channel electromagnetic coil 1013 of at least one touch area 1011 is electrically connected with one channel electromagnetic coil 1013 of another touch area 1011 to form the electromagnetic induction channel 103, in the case of receiving a touch operation, the target touch area where the touch operation is located can be detected and determined through the detection electromagnetic coil 1012, and the target position of the touch operation in the target touch area can be detected and determined through the electromagnetic induction channel 103, so that the accurate positioning of the touch operation is realized; and the channel electromagnetic coils 1013 of different touch areas 1011 are electrically connected to form the electromagnetic induction channel 103, and then the electromagnetic induction channel 103 is connected to the touch driving module 102 through the channel lead 1014, so that the number of channel leads 1014 connected to the touch driving module 102 can be reduced, and the wiring space in the touch screen can be saved.

[0040] Specifically, the touch module 100 can comprise the touch layer 101 and the touch driving module 102, the touch layer 101 can be used to sense the change of magnetic flux generated by the touch operation of an electromagnetic touch end to generate an induction signal, and transmit the induction signal to the touch driving module 102. Wherein, the electromagnetic touch end can comprise an electromagnetic pen, and the touch driving module 102 can comprise an electromagnetic induction chip.

[0041] A plurality of touch areas 1011 are arranged along a preset direction in the touch layer 101, and the whole touch layer 101 is divided into a plurality of different touch operation areas by arranging the plurality of touch areas 1011.

[0042] It should be noted that the number and size of the touch areas 1011 can be determined according to the actual area size of the touch area 1011 of the touch layer 101 and the actual touch frequency of each area in the touch layer 101. The size of different touch areas 1011 can be the same or different, and a person skilled in the art can set it according to actual needs, and the embodiments of the present application do not limit this.

[0043] Further, at least one detection electromagnetic coil 1012 is arranged in each touch area 1011, and each detection electromagnetic coil 1012 is directly connected to the touch driving module 102. At the same time, a plurality of channel electromagnetic coils 1013 are arranged in each touch area 1011, and the plurality of channel electromagnetic coils 1013 are arranged in parallel along a predetermined direction.

[0044] It should be noted that the specific number of detection electromagnetic coils 1012 and channel electromagnetic coils 1013 arranged in different touch areas 1011 can be the same or different, and can be set according to actual needs, and the embodiments of the present application do not limit this.

[0045] Specifically, as shown in Figure 2 , one channel electromagnetic coil 1013 in at least one touch area 1011 is electrically connected to one channel electromagnetic coil 1013 in another touch area 1011 to form an electromagnetic induction channel 103, and the formed electromagnetic induction channel 103 is electrically connected to the touch driving module 102 through a channel lead 1014.

[0046] In the case that the touch layer 101 receives a touch operation, the detection electromagnetic coil 1012 can be used to obtain a target touch area 1011 where the touch operation is located, and the electromagnetic induction channel 103 can be used to determine a target position in the target touch area 1011 where the touch operation is located, and the detection electromagnetic coil 1012 and the electromagnetic induction channel 103 can be used to realize accurate positioning of the touch operation.

[0047] Wherein, the detection electromagnetic coil 1012 and the channel electromagnetic coil 1013 can be annular electromagnetic induction coils, and the specific structure of the detection electromagnetic coil 1012 and the channel electromagnetic coil 1013 can be determined according to the specific structure of the touch area 1011, and the embodiments of the present application do not limit this.

[0048] For example, as shown in Figure 3 , the touch module 100 includes a touch layer 101 and a touch driving module 102, wherein the touch layer 101 includes four touch areas 1011 arranged in sequence along the Y direction, and the information of the detection electromagnetic coil 1012 and the channel electromagnetic coil 1013 included in each touch area 1011 is as shown in Table 1:

[0049] Table 1

[0050] Touch area Detection electromagnetic coil Passage electromagnetic coil a Ta Y1a, Y2a, Y3a b Tb Y1b, Y2b c Tc Y1c, Y2c d Td Y1d, Y3d

[0051] As can be seen from Table 1, the four touch areas 1011 are: touch area a, touch area b, touch area c, and touch area d. Touch area a includes a detection electromagnetic coil Ta and three channel electromagnetic coils Y1a, Y2a, and Y3a; touch area b includes a detection electromagnetic coil Tb and two channel electromagnetic coils Y1b and Y2b; touch area c includes a detection electromagnetic coil Tc and two channel electromagnetic coils Y1c and Y2c; and touch area d includes a detection electromagnetic coil Td and two channel electromagnetic coils Y1d and Y3d.

[0052] By electrically connecting Ta, Tb, Tc, and Td to the touch driver module 102 respectively, and by electrically connecting Y1a, Y1b, Y1c, and Y1d together to form an electromagnetic induction channel Y1, by electrically connecting Y2a, Y2b, and Y2c together to form an electromagnetic induction channel Y2, and by electrically connecting Y3a and Y3d together to form an electromagnetic induction channel Y3, the three electromagnetic induction channels Y1, Y2, and Y3 are electrically connected to the touch driver module 102 respectively through channel leads 1014.

[0053] refer to Figure 4 and Figure 5 , Figure 4 For electromagnetic pen touch control Figure 3 A schematic diagram of the touch area 'a' in the image. Figure 5 for Figure 4 The signal strength of each electromagnetic induction coil, wherein the electromagnetic induction coil includes: detection electromagnetic coil 1012 and channel electromagnetic coil 1013.

[0054] like Figure 4 and Figure 5 As shown, when the electromagnetic pen approaches the touch area a, the electromagnetic coil Ta detects an induction signal, which can locate the touch position of the electromagnetic pen in the touch area a. The signal strength of the electromagnetic induction channel Y2 is greater than the signal strength of the electromagnetic induction channels Y1 and Y3, which determines that the touch position of the electromagnetic pen is close to Y2a. Finally, the precise position information of the touch position can be obtained.

[0055] In some embodiments, in the plurality of touch control areas 1011, one channel electromagnetic coil 1013 in one touch control area 1011 can be electrically connected with one channel electromagnetic coil 1013 in another touch control area 1011 to form one electromagnetic induction channel 103; or one channel electromagnetic coil 1013 in one touch control area 1011 can be electrically connected with one channel electromagnetic coil 1013 in each of the other plurality of touch control areas 1011 in sequence to form one electromagnetic induction channel 103. Of course, the specific connection structure of the plurality of channel electromagnetic coils 1013 forming the electromagnetic induction channel 103 can be set according to actual conditions, and the embodiments of the present application do not limit this.

[0056] It can be understood that in the related art, each channel electromagnetic coil 1013 is directly connected with the touch control driving module 102 through the channel lead 1014, so as to take one channel electromagnetic coil 1013 as one electromagnetic induction channel 103, thereby directly detecting the position information of the touch operation by using each channel electromagnetic coil 1013. However, since the touch control driving module 102 needs to be connected with the channel lead 1014 of each electromagnetic induction coil, the touch control driving module 102 needs to set a large number of connection points, which not only has a complex wiring structure and occupies a large space, but also increases the cost of the touch control driving module 102.

[0057] In the embodiments of the present application, by dividing the touch control layer 101 into a plurality of touch control areas 1011, one channel electromagnetic coil 1013 in each touch control area 1011 in different touch control areas 1011 is electrically connected with one channel electromagnetic coil 1013 in another touch control area 1011 to form an electromagnetic induction channel 103, and then the electromagnetic induction channel 103 is electrically connected with the touch control driving module 102 through the channel lead 1014, so that it is no longer necessary to connect each channel electromagnetic coil 1013 with the touch control driving module 102, the number of channel leads 1014 connected with the touch control driving module 102 can be reduced, the wiring space in the touch screen can be saved, and the cost of the touch control driving module 102 can be reduced.

[0058] In some embodiments, each touch control area 1011 can include a plurality of channel electromagnetic coils 1013 arranged in parallel and spaced apart along a preset direction, at least one channel electromagnetic coil 1013 in the plurality of channel electromagnetic coils 1013 is directly electrically connected with the touch control driving module 102 to form a detection electromagnetic coil 1012, and the channel electromagnetic coils 1013 other than the detection electromagnetic coil 1012 in the plurality of channel electromagnetic coils 1013 are electrically connected with each other to form an electromagnetic induction channel 103, and then the electromagnetic induction channel 103 is electrically connected with the touch control driving module 102.

[0059] In the case that the touch control layer 101 receives a touch control operation, when it is detected that the touch control operation is located in the area where the detection electromagnetic coil 1012 is located, the position information of the touch control operation can be directly determined; when it is detected that the touch control operation is located in an area outside the area where the detection electromagnetic coil 1012 is located, the target touch control area 1011 where the touch control operation is located is first determined by the detection electromagnetic coil 1012, and then the target position of the touch control operation in the target touch control area 1011 is determined by the electromagnetic induction channel 103, so as to determine the position information of the touch control operation.

[0060] Optionally, with reference to Figure 6 , the touch control module comprises: a first touch control layer and a second touch control layer, the first touch control layer and the second touch control layer are arranged in a stack and are insulated from each other; a preset direction of the first touch control layer is a first direction X, and a plurality of first touch control areas are arranged in the first touch control layer along the first direction X; a preset direction of the second touch control layer is a second direction Y, and a plurality of second touch control areas are arranged in the second touch control layer along the second direction Y, and the first direction X is perpendicular to the second direction Y.

[0061] In the embodiments of the present application, the touch control module 100 is provided with two touch control layers 101, the two touch control layers 101 are arranged in a stack and are insulated from each other, and the preset directions of the two touch control layers 101 are perpendicular to each other, so that in the case that a touch control operation is received, the two-dimensional coordinate information of the position where the touch control operation is located can be determined by the two touch control layers 101 at the same time, thereby realizing accurate positioning of the touch control operation.

[0062] Specifically, the touch control module 100 is provided with two touch control layers 101, which are a first touch control layer and a second touch control layer, the two touch control layers 101 are arranged in a stack, and the two touch control layers 101 are insulated from each other.

[0063] The preset direction of the first touch control layer is a first direction X, a plurality of first touch control areas are arranged in the first touch control layer along the first direction X, the plurality of first touch control areas are arranged in parallel along the first direction X, each first touch control area comprises a detection electromagnetic coil 1012 and a plurality of channel electromagnetic coils 1013, and the plurality of electromagnetic induction coils 1013 in each first touch control area are arranged in parallel and spaced apart along the first direction X.

[0064] In the first touch control layer, one channel electromagnetic coil 1013 of at least one first touch control area is electrically connected with one channel electromagnetic coil 1013 of another first touch control area to form an electromagnetic induction channel 103 of the first touch control layer, a plurality of electromagnetic induction channels 103 can be formed in the first touch control layer, and the electromagnetic induction channel 103 of the first touch control layer and the detection electromagnetic coil 1012 are electrically connected with the touch control driving module 102 respectively.

[0065] In the case that the first touch layer receives the touch operation, the detection electromagnetic coil 1012 of the first touch layer is used to obtain a target touch area in which the touch operation is located in the first touch layer, and the electromagnetic induction channel 103 of the first touch layer is used to determine a target position of the touch operation in the target touch area in the first touch layer.

[0066] Correspondingly, the preset direction of the second touch layer is the second direction Y, a plurality of second touch areas are arranged along the second direction Y in the second touch layer, the plurality of second touch areas are arranged along the second direction Y, each second touch area includes the detection electromagnetic coil 1012 and a plurality of channel electromagnetic coils 1013, and the plurality of electromagnetic induction coils 1013 in each second touch area are arranged in parallel and spaced apart along the second direction Y.

[0067] In the second touch layer, one channel electromagnetic coil 1013 of at least one second touch area is electrically connected with one channel electromagnetic coil 1013 of another second touch area to form one electromagnetic induction channel 103 in the second touch layer, a plurality of electromagnetic induction channels 103 can be formed in the second touch layer, and the electromagnetic induction channel 103 and the detection electromagnetic coil 1012 of the second touch layer are electrically connected with the touch driving module respectively.

[0068] In the case that the second touch layer receives the touch operation, the detection electromagnetic coil 1012 of the second touch layer is used to obtain a target touch area in which the touch operation is located in the second touch layer, and the electromagnetic induction channel 103 of the second touch layer is used to determine a target position of the touch operation in the target touch area in the second touch layer. Further, the first direction X and the second direction Y are perpendicular to each other, so that in the case that the touch module 100 receives the touch operation, the first touch layer and the second touch layer in the touch module 100 receive the touch operation at the same time, wherein the position information of the touch operation in the first direction X can be determined by using the detection electromagnetic coil 1012 and the electromagnetic induction channel 103 in the first touch layer, and the position information of the touch operation in the second direction Y can be determined by using the detection electromagnetic coil 1012 and the electromagnetic induction channel 103 in the second touch layer, and then the two-dimensional coordinate information of the touch operation in the touch module 100 can be obtained, and the accurate positioning of the touch operation is realized.

[0069] In some embodiments, the first direction X and the second direction Y can correspond to the X axis and the Y axis in the Cartesian coordinate system respectively, so that the X and Y coordinates corresponding to the position of the touch operation can be obtained by the two touch layers 101, and then the touch driving module 102 is transmitted by the two touch layers 101 to be used for subsequent interactive control.

[0070] Optionally, each touch area 1011 includes a plurality of detection electromagnetic coils 1012, and the plurality of detection electromagnetic coils 1012 are arranged at intervals.

[0071] In the embodiment of the present application, each of the plurality of touch control areas 1011 can be provided with a plurality of detection electromagnetic coils 1012, and the plurality of detection electromagnetic coils 1012 are arranged at intervals, so that the positioning accuracy of the target touch control area 1011 where the touch operation is located in the touch control layer 101 can be improved.

[0072] In the touch control layer 101, a plurality of touch control areas 1011 are arranged, and the plurality of touch control areas 1011 divide the touch control layer 101 into a plurality of touch control areas. It can be understood that if the area of one of the touch control areas 1011 is large, and only one detection electromagnetic coil 1012 is arranged in the touch control area 1011, when the position where the touch operation is located in the touch control area 1011 is far away from the detection electromagnetic coil 1012, the detection sensitivity of the detection electromagnetic coil 1012 will decrease, which affects the positioning accuracy in the touch control area 1011. Therefore, by arranging a plurality of detection electromagnetic coils 1012 at intervals in each touch control area 1011, the positioning accuracy of the target touch control area 1011 where the touch operation is located in the touch control layer 101 can be improved.

[0073] It should be noted that in the plurality of touch control areas 1011, the specific number of detection electromagnetic coils 1012 arranged in different touch control areas 1011 can be the same or different, and can be determined according to the actual area size of the corresponding touch control area 1011. In addition, the specific layout structure of the plurality of detection electromagnetic coils 1012 in each touch control area 1011 can be set according to actual needs, and the embodiment of the present application does not limit this.

[0074] Optionally, with reference to Figure 7 to Figure 9 The electrical connection mode between the plurality of channel electromagnetic coils 1013 forming the electromagnetic induction channel 103 includes at least one of series connection and parallel connection.

[0075] In the embodiment of the present application, the plurality of channel electromagnetic coils 1013 forming the electromagnetic induction channel 103 can be electrically connected in at least one of series connection and parallel connection, so as to realize flexible circuit arrangement of the plurality of channel electromagnetic coils 1013 in the electromagnetic induction channel 103, thereby meeting the circuit connection requirements of the touch control module 100 in different application scenarios, and improving the applicability of the touch control module 100.

[0076] Specifically, in the plurality of touch control areas 1011, each channel electromagnetic coil 1013 of at least one touch control area 1011 is electrically connected with one channel electromagnetic coil 1013 of another touch control area 1011, so as to form the electromagnetic induction channel 103. The electrical connection mode between the plurality of channel electromagnetic coils 1013 forming one electromagnetic induction channel 103 can include at least one of series connection and parallel connection.

[0077] Taking the electromagnetic induction channel 103 corresponding to Table 1 as an example, as shown in Figure 7 , the channel electromagnetic coils Y1a, Y1b, Y1c and Y1d are sequentially connected together in parallel to form an electromagnetic induction channel Y1, and the electromagnetic induction channel Y1 is electrically connected with the touch driving module 102.

[0078] As shown in Figure 8 , the channel electromagnetic coils Y1a, Y1b, Y1c and Y1d can also be sequentially connected together in series to form an electromagnetic induction channel Y1, and the electromagnetic induction channel Y1 is electrically connected with the touch driving module 102.

[0079] As shown in Figure 9 , the channel electromagnetic coils Y1a and Y1b can also be connected in series, and the channel electromagnetic coils Y1c and Y1d can also be connected in series, and then the series-connected Y1a and Y1b and the series-connected Y1c and Y1d are further connected together in parallel to form an electromagnetic induction channel Y1, and then the electromagnetic induction channel Y1 is electrically connected with the touch driving module 102.

[0080] It should be noted that the specific electrical connection mode of the plurality of channel electromagnetic coils 1013 forming the electromagnetic induction channel 103 can be determined according to the driving and sensing performance of the touch driving module 102 and the circuit setting requirements of the touch module 100, and a person skilled in the art can set it according to actual needs, and the embodiments of the present application do not limit it.

[0090] The insulating layer can be made of an organic insulating material, for example, an insulating resin material, an insulating rubber material, or the like, or can be made of an inorganic material, for example, silicon dioxide, silicon oxynitride, silicon nitride, or the like. Of course, the specific material of the insulating layer can be determined according to actual needs, and the embodiment of the present application does not limit this.

[0091] It should be noted that the touch layer 101 and the metal layer 201 are arranged in the same layer, the circuit of the touch layer 101 can be connected to the circuit of the metal layer 201, so as to share the circuit, and the functions of the display module 200 and the touch module 100 can be realized by time division multiplexing, so as to simplify the overall wiring structure and save wiring space.

[0092] The circuit lines of the touch layer 101 and the metal layer 201 can be separately arranged, and the touch layer 101 and the metal layer 201 are insulated, so as to realize the respective circuit control of the touch layer 101 and the metal layer 201. Of course, the specific circuit connection of the touch layer 101 and the metal layer 201 can be determined according to the actual structure of the touch layer 101 and the metal layer 201, and the present application will not be repeated here.

By arranging the touch layer 101 and the metal light shielding layer in the same layer, the electromagnetic touch sensing performance of the touch layer 101 is realized while the light shielding and shielding functions of the metal light shielding layer are realized, so as to reduce the overall thickness of the display screen.

[0095] Specifically, the metal light shielding layer includes a plurality of rows of pixel light shielding metals 2011, and the plurality of rows of pixel light shielding metals 2011 are arranged in parallel and at intervals along a preset direction. The pixel light shielding metal 2011 can be made of titanium Ti, aluminum Al, molybdenum Mo or other metal materials, of course, other metal materials can also be used, which can be determined according to actual needs, and the present application does not limit this.

[0096] The specific size of the pixel light shielding metal 2011 can be determined according to the pixel display parameters of the display module 200, for example: the height and width of a single row of pixels in the display module 200 are 1nm to 100um, and the height and width of the single row of pixel light shielding metals 2011 can be arranged correspondingly. The specific size of the pixel light shielding metal 2011 can be determined according to actual needs, and the present application does not limit this.

[0097] Optionally, referring to Figure 12 At least two rows of pixel light shielding metals 2011 are electrically connected to each other to form a detection electromagnetic coil 1012 or a channel electromagnetic coil 1013 of the touch layer 101.

[0098] In this embodiment, at least two rows of pixel light-shielding metal 2011 are electrically connected to each other to form the detection electromagnetic coil 1012 or channel electromagnetic coil 1013 of the touch layer 101, thereby realizing the co-layering of the metal light-shielding layer and the touch layer 101. Furthermore, by directly forming the detection electromagnetic coil 1012 or channel electromagnetic coil 1013 of the touch layer 101 using the pixel light-shielding metal 2011, not only can the overall thickness of the display screen be reduced, achieving a thinner and lighter display screen, but also the utilization rate of the metal light-shielding layer can be improved, the circuit layout can be simplified, and the wiring space in the display screen can be further saved.

[0099] Specifically, at least two rows of pixel light-shielding metal 2011 can be electrically connected to each other to form a ring-shaped electromagnetic induction coil. This ring-shaped electromagnetic induction coil can serve as the detection electromagnetic coil 1012 or the channel electromagnetic coil 1013 of the touch layer 101.

[0100] like Figure 12 As shown, multiple rows of pixel light-shielding metal 2011 can be connected in series and / or in parallel to form a ring electromagnetic induction coil. This ring electromagnetic induction coil can be used as a detection electromagnetic coil 1012 and directly connected to the touch driving module 102 in the touch module 100.

[0101] Of course, the above-mentioned ring electromagnetic induction coil can also be used as a channel electromagnetic coil 1013. By electrically connecting multiple ring electromagnetic induction coils in different areas of the display screen, an electromagnetic induction channel 103 is formed, and the electromagnetic induction channel 103 is connected to the touch driving module 102 in the touch module 100.

By setting the preset space in the ring-shaped electromagnetic induction coil, the pixel light shielding metal 2011 in the preset space is not connected with other pixel light shielding metals 2011, so that the influence of the pixel light shielding metal 2011 in the preset space on the electromagnetic induction strength of the ring-shaped electromagnetic induction coil can be reduced, and the magnetic induction accuracy of the ring-shaped electromagnetic induction coil can be improved.

[0107] Specifically, the metal light shielding layer includes multiple rows of pixel light shielding metals 2011 arranged in parallel and at intervals along a preset direction, and the layout structure of the detection electromagnetic coil 1012 or the channel electromagnetic coil 1013 of the touch layer 101 is set such that each detection electromagnetic coil 1012 or each channel electromagnetic coil 1013 is arranged around one or more rows of pixel light shielding metals 2011, so that the detection electromagnetic coil 1012 or the channel electromagnetic coil 1013 is arranged in the same layer as the pixel light shielding metal 2011.

[0108] As shown in Figure 13 , two channel electromagnetic coils 1013 can be arranged, each of which is arranged around one row of pixel light shielding metals 2011, and the two channel electromagnetic coils 1013 are connected in series to form an electromagnetic induction channel 103, and the electromagnetic induction channel 103 is connected with the touch driving module 102.

[0109] One detection electromagnetic coil 1012 can also be arranged around one or more rows of pixel light shielding metals 2011, and the detection electromagnetic coil 1012 is connected with the touch driving module 102.
