Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display module. Background Technology

[0002] With the continuous development of display technology, touch technology has been widely applied to various electronic products in daily work and life. Since users can directly touch the display module with their hands or other objects to input information, it reduces or even eliminates users' reliance on other input devices (such as keyboards, mice, remote controls, etc.), making operation more convenient. Touch technology includes electromagnetic touch, capacitive touch, and resistive film touch, among others. Electromagnetic touch technology utilizes a coil in a specific electromagnetic pen to cause a change in the magnetic field of the electromagnetic induction coil on the display module, thereby generating a weak current. The touch detection part then calculates the position of the touch point.

[0003] Currently, electromagnetic touch display modules typically use an external electromagnetic touch panel, which is then combined with the display panel to form the electromagnetic touch display module. However, this type of electromagnetic touch display module has a complex structure and a relatively large overall thickness, resulting in high production costs.

The electromagnetic touch coils 23 have a double-layer conductive structure, and some of the electromagnetic touch coils 23 are disposed in the same layer as the capacitive touch electrodes 21.

[0072] In the embodiments of this application, by integrating the electromagnetic touch coil 23 into the touch layer 2 containing the capacitive touch electrode 21, the electromagnetic touch coil 23 is partially disposed between adjacent capacitive touch electrodes 21, and the electromagnetic touch coil 23 is configured as a double-layer conductive structure, so that part of the electromagnetic touch coil 23 and the capacitive touch electrode 21 are disposed in the same layer, the film layer structure of the display module can be simplified and the thickness of the display module can be reduced, thereby reducing the production cost of the display module.

[0073] In some embodiments, please refer to Figure 5 The electromagnetic touch coil 23 includes a drive coil 231 and an induction coil 232. The drive coil 231 and the induction coil 232 are arranged intersectingly.

[0074] In some embodiments, please refer to Figures 6 to 9 ,in, Figure 6 A schematic diagram of the structure of the capacitive touch electrode and the electromagnetic touch coil in the display module provided for embodiments of this application. Figure 7 for Figure 6 An enlarged view of point a in the middle. Figure 8 for Figure 7 A schematic diagram of the first conductive layer at point a. Figure 9 for Figure 7 The schematic diagram of the second conductive layer at point a shows that the driving coil 231 includes a first sub-driving coil 2311 and a second sub-driving coil 2312. The first sub-driving coil 2311 and the second sub-driving coil 2312 are arranged in different layers and are connected in parallel. By setting the driving coil 231 as a double-layer conductive structure and connecting the first sub-driving coil 2311 and the second sub-driving coil 2312 in parallel, the impedance of the driving coil 231 can be reduced.

[0075] In some embodiments, please refer to Figures 6 to 7 The induction coil 232 includes a first sub-induction coil 2321 and a second sub-induction coil 2322, which are connected in parallel. By setting the induction coil 232 to a double-layer conductive structure and connecting the first sub-induction coil 2321 and the second sub-induction coil 2322 in parallel, the impedance of the induction coil 232 can be reduced.

[0076] In some embodiments, the first sub-induction coil 2321 is disposed on the same layer as the first sub-drive coil 2311 and is insulated therefrom, and the second sub-induction coil 2322 is disposed on the same layer as the second sub-drive coil 2312 and is insulated therefrom.

[0078] In some embodiments, please refer to Figure 2 and Figure 7 The first insulating layer 203 has multiple first vias V1 and multiple second vias V2. The second sub-driving coil 2312 in the second conductive layer 202 is connected to the first sub-driving coil 2311 through the first vias V1, thereby achieving parallel connection between the first sub-driving coil 2311 and the second sub-driving coil 2312, which can reduce the impedance of the driving coil 231. The second sub-induction coil 2322 in the second conductive layer 202 is connected to the first sub-induction coil 2321 through the second vias V2, thereby achieving parallel connection between the first sub-induction coil 2321 and the second sub-induction coil 2322, which can reduce the impedance of the induction coil 232.

[0080] Please see Figures 6 to 9The area where the first sub-sensing part 23221 overlaps with the first sub-sensing coil 2321 is the area where the driving coil 231 and the sensing coil 232 intersect. In the area where the driving coil 231 and the sensing coil 232 intersect, both the driving coil 231 and the sensing coil 232 are single-layer structures. The first sub-driving coil 2311 of the driving coil 231 and the second sub-sensing coil 2322 of the sensing coil 232 overlap in this area. This can prevent the driving coil 231 and the sensing coil 232 from short-circuiting and causing touch failure.

[0081] In the embodiments of this application, please refer to Figure 2 The thickness direction of the touch layer refers to Figure 2 The third direction Z is shown, and the third direction Z is perpendicular to the plane defined by the first direction X and the second direction Y.

[0082] In some embodiments, please refer to Figure 8 The touch layer 2 also includes a first floating electrode 2011, which is disposed in the same layer as the first sub-driving coil 2311.

In practical applications, the number of first floating electrodes 2011 disposed between the second sub-driving part 23112 and the first sub-induction coil 2321 is not limited to one row as in the above embodiment, but can also be two or more rows.

[0085] In some embodiments, please refer to Figure 9The touch layer 2 also includes a second floating electrode 2012, which is disposed in the same layer as the second sub-driving coil 2312, i.e., the second conductive layer 202 includes the second floating electrode 2012. The second sub-driving coil 2312 and the second sub-sensing part 23222 are insulated from each other, and the second floating electrode 2012 is disposed between the second sub-driving coil 2312 and the second sub-sensing part 23222.

Along the film thickness direction of the touch layer, the second floating electrode 2012 overlaps with the first sub-driving coil 2311.

[0086] In this embodiment, by adding a second floating electrode 2012 between the second sub-driving coil 2312 and the second sub-sensing part 23222, the situation where the touch control fails due to short circuit between the second sub-driving coil 2312 and the second sub-sensing part 23222 can be avoided.

[0087] In some embodiments, please refer to Figure 9 The touch layer 2 includes a plurality of second floating electrodes 2012, which are arranged at intervals along a first direction X between the second sub-driving coil 2312 and the second sub-sensing part 23222. A row of second floating electrodes 2012 is provided between the second sub-driving coil 2312 and the second sub-sensing part 23222. In practical applications, the number of second floating electrodes 2012 provided between the second sub-driving coil 2312 and the second sub-sensing part 23222 is not limited to one row as in the above embodiment, but can also be two or more rows.

[0088] In some embodiments, please refer to Figure 6 The capacitive touch electrode 21 includes a first touch electrode 211 and a second touch electrode 212.

[0089] In some embodiments, please refer to Figure 6 , Figures 10 to 12 ,in Figure 10 for Figure 6 An enlarged view of point b in the middle. Figure 11 for Figure 6 A schematic diagram of the first conductive layer at point b. Figure 12 for Figure 6 The schematic diagram of the second conductive layer at point b shows that the first touch signal line 221 and the second sub-drive coil 2312 are disposed on the same layer, that is, the second conductive layer 202 includes the first touch signal line 221 and the second touch signal line 222.

[0090] Please see Figures 10 to 12 The first sub-driving coil 2311 also includes a third sub-driving part 23113, which is connected to the first sub-driving part 23111. Along the film thickness direction of the touch layer, the third sub-driving part 23113 overlaps with the first touch signal line 221.

[0091] In some embodiments, please refer to Figures 10 to 12 The driving coil 231 and the first touch signal line 221 are arranged to intersect. In the area where the driving coil 231 and the first touch signal line 221 intersect, both the driving coil 231 and the first touch signal line 221 are single-layer structures. In the area where the driving coil 231 and the first touch signal line 221 intersect, the driving coil 231 is only provided with a third sub-driving part 23113. The third sub-driving part 23113 is arranged to overlap with the first touch signal line 221 in this area. This can avoid the situation where the driving coil 231 and the first touch signal line 221 are short-circuited, which would cause touch failure, thereby improving the process yield of the display module.

[0092] In some embodiments, please refer to Figure 12 The touch layer 2 also includes a third floating electrode 2013, which is disposed in the same layer as the second sub-driving coil 2312, i.e., the second conductive layer 202 includes the third floating electrode 2013. The second sub-driving coil 2312 is insulated from the first touch signal line 221, and the third floating electrode 2013 is disposed between the second sub-driving coil 2312 and the first touch signal line 221. The third floating electrode 2013 is insulated from both the second sub-driving coil 2312 and the first touch signal line 221. Along the film thickness direction of the touch layer, the third floating electrode 2013 overlaps with the first sub-driving coil 2311.

[0093] By adding a third floating electrode 2013 between the second sub-driving coil 2312 and the first touch signal line 221, it can prevent the touch from failing due to a short circuit between the second sub-driving coil 2312 and the first touch signal line 221. On the other hand, it can reduce the overlapping area of ​​the driving coil 231 and the first touch signal line 221, thereby reducing the parasitic capacitance between the driving coil 231 and the first touch signal line 221, thus improving the sensitivity and accuracy of capacitive touch and electromagnetic touch.

[0094] In some embodiments, please refer to Figure 12The touch layer 2 includes multiple third floating electrodes 2013, which are spaced apart along a first direction X between the second sub-driving coil 2312 and the first touch signal line 221.

In practical applications, two or more rows of third floating electrodes 2013 may also be provided between the second sub-driving coil 2312 and the first touch signal line 221.

[0095] In some embodiments, please refer to Figure 11 The touch layer 2 also includes a fourth floating electrode 2014, which is disposed in the same layer as the first sub-driving coil 2311. That is, the first conductive layer 201 includes the fourth floating electrode 2014, which is located on one side of the third sub-driving part 23113. Along the thickness direction of the touch layer, the fourth floating electrode 2014 overlaps with the first touch signal line 221. This further reduces the overlapping area of ​​the driving coil 231 and the first touch signal line 221, thereby reducing the parasitic capacitance between them and improving the sensitivity and accuracy of capacitive and electromagnetic touch.

[0096] In some embodiments, please refer to Figure 11 The touch layer 2 includes a plurality of fourth floating electrodes 2014, which are arranged at intervals along the second direction Y on one side of the third sub-driving unit 23113. A row of fourth floating electrodes 2014 is provided on one side of the third sub-driving unit 23113. In practical applications, two or more rows of fourth floating electrodes 2014 can be provided on one side of the third sub-driving unit 23113.

[0097] In some embodiments, please refer to Figures 10 to 12 The touch layer 2 also includes a fifth floating electrode 2015, which is disposed in the same layer as the first touch signal line 221, i.e., the second conductive layer 202 includes the fifth floating electrode 2015. The first touch signal line 221 has a first opening 2211, and a plurality of fifth floating electrodes 2015 are spaced apart in the first opening 2211 along a first direction X. The first touch signal line 221 is disposed around the fifth floating electrode 2015. Along the film thickness direction of the touch layer, the fifth floating electrode 2015 overlaps with the third sub-driving part 23113 of the first sub-driving coil 2311.

[0098] By setting the overlapping portion of the first touch signal line 221 and the first sub-drive coil 2311 as a floating electrode, the overlapping area of ​​the drive coil 231 and the first touch signal line 221 can be further reduced, thereby further reducing the parasitic capacitance between the drive coil 231 and the first touch signal line 221, which can further improve the sensitivity and accuracy of capacitive touch and electromagnetic touch.

[0099] In some embodiments, please refer to Figure 6 , Figures 13 to 15 , Figure 13 for Figure 6 An enlarged view of point c in the middle. Figure 14 for Figure 6 A schematic diagram of the first conductive layer at point c. Figure 15 for Figure 6 A schematic diagram of the second conductive layer at point c. The second touch signal line 222 and the second sub-sensing coil 2322 are disposed on the same layer. The second conductive layer 202 includes the second touch signal line 222. The first sub-sensing coil 2321 includes a third sub-sensing part 23211 and a fourth sub-sensing part 23212. Along the film thickness direction of the touch layer, the third sub-sensing part 23211 overlaps with the first sub-sensing part 23221, and the fourth sub-sensing part 23212 overlaps with the second touch signal line 222.

[0100] In some embodiments, please refer to Figures 13 to 15 The induction coil 232 and the second touch signal line 222 are arranged to cross each other. In the area where the induction coil 232 and the second touch signal line 222 intersect, both the induction coil 232 and the second touch signal line 222 are single-layer conductive structures. That is, in the area where the induction coil 232 and the second touch signal line 222 intersect, the induction coil 232 is only provided with a fourth sub-sensing part 23212. The fourth sub-sensing part 23212 overlaps with the second touch signal line 222 in this area. This can avoid the situation where the induction coil 232 and the second touch signal line 222 are short-circuited, which would cause touch failure, thereby improving the process yield of the display module.

[0101] In some embodiments, please refer to Figures 13 to 15 The touch layer 2 also includes a sixth floating electrode 2016, which is disposed in the same layer as the second sub-induction coil 2322, i.e., the second conductive layer 202 includes the sixth floating electrode 2016. The first sub-sensing part 23221 and the second touch signal line 222 are insulated from each other, and the sixth floating electrode 2016 is disposed between the first sub-sensing part 23221 and the second touch signal line 222, and is insulated from the first sub-sensing part 23221 and the second touch signal line 222. Along the film thickness direction of the touch layer, the sixth floating electrode 2016 overlaps with the first sub-induction coil 2321.

[0102] By adding a sixth floating electrode 2016 between the first sub-sensing unit 23221 and the second touch signal line 222, it is possible to prevent the touch control from failing due to a short circuit between the first sub-sensing unit 23221 and the second touch signal line 222. On the other hand, it can reduce the overlapping area of ​​the sensing coil 232 and the second touch signal line 222, thereby reducing the parasitic capacitance between the sensing coil 232 and the second touch signal line 222, which can improve the sensitivity and accuracy of capacitive touch and electromagnetic touch.

[0103] In some embodiments, please refer to Figures 13 to 15 The touch layer 2 includes a plurality of sixth floating electrodes 2016, which are arranged at intervals along the second direction Y between the second sub-sensing unit 23222 and the second touch signal line 222. A row of sixth floating electrodes 2016 is provided between the second sub-sensing unit 23222 and the second touch signal line 222. In practical applications, the second sub-sensing unit 23222 and the second touch signal line 222 may also be provided with two or more rows of sixth floating electrodes 2016.

[0104] In some embodiments, please refer to Figures 13 to 15 The touch layer 2 also includes a seventh floating electrode 2017, which is disposed on the same layer as the first sub-induction coil 2321, that is, the first conductive layer 201 includes the seventh floating electrode 2017. The seventh floating electrode 2017 is disposed on one side of the fourth sub-induction unit 23212, and along the film thickness direction of the touch layer, the seventh floating electrode 2017 partially overlaps with the second touch signal line 222.

[0105] In some embodiments, please refer to Figures 13 to 15 The touch layer 2 includes a plurality of seventh floating electrodes 2017, which are arranged at intervals along a first direction X on one side of the fourth sub-sensing unit 23212. One row of seventh floating electrodes 2017 is provided on one side of the fourth sub-sensing unit 23212. In practical applications, two or more rows of seventh floating electrodes 2017 can be provided on one side of the fourth sub-sensing unit 23212.

[0106] In some embodiments, please refer to Figures 13 to 15 The touch layer 2 also includes a plurality of eighth floating electrodes 2018, which are disposed in the same layer as the second touch signal line 222, that is, the second conductive layer 202 includes the eighth floating electrodes 2018. The second touch signal line 222 has a second opening 2221. The plurality of eighth floating electrodes 2018 are spaced apart by the second openings 2221 along the second direction Y. Along the film thickness direction of the touch layer, the eighth floating electrodes 2018 overlap with the fourth sub-sensing part 23212.

[0107] By setting the overlapping portion of the second touch signal line 222 and the fourth sub-sensing part 23212 of the first sub-sensing coil 2321 as a floating electrode, the overlapping area of ​​the induction coil 232 and the second touch signal line 222 can be further reduced, thereby further reducing the parasitic capacitance between the induction coil 232 and the second touch signal line 222, and thus further improving the sensitivity and accuracy of capacitive touch and electromagnetic touch.

[0108] In some embodiments, please refer to Figure 6 and Figure 16 , Figure 16 for Figure 6 The enlarged schematic diagram at point d shows that the capacitive touch electrode 21 includes a first touch electrode 211 and a second touch electrode 212. The touch layer 2 also includes a ninth floating electrode 2019, which is disposed in the same layer as the first touch electrode 211. That is, the second conductive layer 202 includes the ninth floating electrode 2019, which is located between the first touch electrode 211 and the second touch electrode 212. By adding the ninth floating electrode 2019 between the first touch electrode 211 and the second touch electrode 212, the situation where the first touch electrode 211 and the second touch electrode 212 are short-circuited, causing touch failure, can be prevented.

[0109] In some embodiments, please refer to Figure 16 The touch layer 2 also includes a tenth floating electrode 2020, which is disposed in the same layer as the first touch electrode 211, that is, the second conductive layer 202 includes the tenth floating electrode 2020. The first touch electrode 211 has at least one third opening 2110, and the tenth floating electrode 2020 is disposed in the third opening 2110. The tenth floating electrode 2020 and the first touch electrode 211 are spaced apart and insulated from each other.

[0110] By setting some electrodes in the first touch electrode 211 as floating electrodes, the overlapping area between the first touch electrode 211 and the cathode layer in the display panel can be reduced, thereby reducing the parasitic capacitance between the first touch electrode 211 and the cathode layer. This can improve the sensitivity and accuracy of capacitive touch while improving the display effect.

[0111] In some embodiments, please refer to Figure 6 The touch layer 2 also includes an eleventh floating electrode 2021, which is disposed in the same layer as the second touch electrode 212, that is, the second conductive layer 202 includes the eleventh floating electrode 2021. The second touch electrode 212 has at least one fourth opening 2120, and the eleventh floating electrode 2021 is disposed in the fourth opening 2120. The eleventh floating electrode 2021 and the second touch electrode 212 are disposed insulated from each other.

[0112] By setting some electrodes in the second touch electrode 212 as floating electrodes, the overlapping area between the second touch electrode 212 and the cathode layer in the display panel can be reduced, thereby reducing the parasitic capacitance between the second touch electrode 212 and the cathode layer. This can improve the sensitivity and accuracy of capacitive touch while improving the display effect.

[0113] In some embodiments, please refer to Figure 16 The first touch electrode 211 includes a first main stem 2111, a plurality of first branch stems 2112 and a plurality of first branches 2113. The first main stem 2111 extends along the second direction Y, the first branch stems 2112 extend along the first direction X, the plurality of first branch stems 2112 are respectively connected to opposite sides of the first main stem 2111, and the first branches 2113 extend along the second direction Y and are connected to one side of the first branch stem 2112.

[0114] In some embodiments, please refer to Figure 16 Each of the first main stem 2111, the first branch stem 2112, and the first branch 2113 is provided with a third opening 2110. Each third opening 2110 is provided with a tenth floating electrode 2020, which can reduce the overlapping area between the first touch electrode 211 and the cathode layer in the display panel, thereby reducing the parasitic capacitance between the first touch electrode 211 and the cathode layer. This can improve the sensitivity and accuracy of capacitive touch while improving the display effect.

[0115] In some embodiments, please refer to Figure 16 The second touch electrode 212 includes two sub-touch electrodes 2121 and at least two bridging portions 2122. The two sub-touch electrodes 2121 are respectively disposed on opposite sides of the first main body 2111. The first touch electrode 211 and the sub-touch electrodes 2121 are disposed in the same layer and are both disposed in the second conductive layer 202. The sub-touch electrodes 2121 and the bridging portions 2122 are disposed in different layers and are disposed in the first conductive layer 201. The two sub-touch electrodes 2121 are connected through at least two bridging portions 2122. By using at least two bridging portions 2122 to connect the two sub-touch electrodes 2121 located on both sides of the first main body 2111, it is possible not only to prevent the first touch electrode 211 and the second touch electrode 212 from short-circuiting and causing touch failure, but also to reduce the impedance of the second touch electrode 212, thereby improving the sensitivity and accuracy of capacitive touch.

[0116] In some embodiments, please refer to Figure 16The sub-touch electrode 2121 includes a second main stem 21211, two second branch stems 21212 and a plurality of second branches 21213. The second main stem 21211 extends along the second direction Y, the second branch stems 21212 extend along the first direction X, and the second branch stems 21212 are connected to the side of the second main stem 21211 close to the first main stem 2111. The second branches 21213 extend along the second direction Y and are connected to the opposite sides of the second branch stems 21212.

[0117] In some embodiments, please refer to Figure 16 The second branch 21212 and the second branch 21213 are each provided with a fourth opening 2120. The fourth opening 2120 is provided along the extension direction of the second branch 21212 or the second branch 21213. Each fourth opening 2120 is provided with an eleventh floating electrode 2021. This can reduce the overlapping area between the second touch electrode 212 and the cathode layer in the display panel, thereby reducing the parasitic capacitance between the second touch electrode 212 and the cathode layer. This can improve the display effect while improving the sensitivity and accuracy of capacitive touch.

[0118] In some embodiments, the display panel 1 includes a plurality of sub-pixels 10, and the capacitive touch electrode 21 has a plurality of first light-transmitting holes 213, which are aligned with a portion of the sub-pixels 10 along the film thickness direction of the touch layer.

[0119] In some embodiments, please refer to Figure 17 , Figure 17 for Figure 16 The enlarged schematic diagram of part e shows that the display panel 1 includes multiple sub-pixels 10, each of which is an organic light-emitting diode. For example, sub-pixels 10 include red sub-pixels 101, green sub-pixels 102, and blue sub-pixels 103.

[0120] Please see Figure 17 Multiple first light-transmitting holes 213 are formed on the first touch electrode 211 and the second touch electrode 212. Taking the first touch electrode 211 as an example, multiple first light-transmitting holes 213 penetrate the corresponding first touch electrode 211 along the film thickness direction of the touch layer, so that the first touch electrode 211 presents a grid shape, and each light-transmitting hole 213 is aligned with a corresponding sub-pixel 10.

[0121] In some embodiments, the shape of the first light-transmitting aperture 213 can be adapted to the shape of the sub-pixel 10. For example, if the sub-pixel 10 is circular, the shape of the first light-transmitting aperture 213 can also be circular. In addition, the shape of the light-transmitting aperture 213 can also be elliptical or rounded rectangle, etc.

[0122] In some embodiments, the size of the first light-transmitting aperture 213 is greater than or equal to the size of the sub-pixel 10. This prevents the capacitive touch electrode 21 from blocking the sub-pixel 10, thus reducing the light emission efficiency of the display panel. It should be noted that the size of the first light-transmitting aperture 213 referred to here is either the diameter of the first light-transmitting aperture 213 or the diameter of its circumscribed circle, and the size of the sub-pixel 10 is either the diameter of the sub-pixel 10 or the diameter of its circumscribed circle.

[0123] In some embodiments, please refer to Figures 7 to 9 The electromagnetic touch coil 23 has a plurality of second light-transmitting holes 233, and each second light-transmitting hole 233 is aligned with a corresponding sub-pixel 10 along the film thickness direction of the touch layer.

[0124] In some embodiments, please refer to Figure 8 The second light-transmitting hole 233 includes a first sub-light-transmitting hole 2331. Multiple first sub-light-transmitting holes 2331 are formed on the first sub-driving coil 2311 so that the first sub-driving coil 2311 presents a grid shape. Each first sub-light-transmitting hole 2331 is aligned with a corresponding sub-pixel, which can improve the light transmittance of the display module.

[0125] In some embodiments, please refer to Figure 9 The second light-transmitting hole 233 includes a second sub-light-transmitting hole 2332. Multiple second sub-light-transmitting holes 2332 are formed on the second sub-driving coil 2312 so that the second sub-driving coil 2312 presents a grid shape. Each second sub-light-transmitting hole 2332 is aligned with a corresponding sub-pixel, which can improve the light transmittance of the display module.

[0126] Please see Figures 7 to 9 In the area where the first sub-driving coil 2311 and the second sub-driving coil 2312 overlap, the first sub-light-transmitting hole 2331 and the corresponding second sub-light-transmitting hole 2332 are aligned, that is, the orthographic projection of the first sub-light-transmitting hole 2331 on the display panel and the orthographic projection of the corresponding second sub-light-transmitting hole 2332 on the display panel completely overlap. This can prevent the first sub-driving coil 2311 and the second sub-driving coil 2312 from blocking the sub-pixels, thereby improving the light transmittance of the display module.

[0127] In some embodiments, a plurality of second light-transmitting holes 233 are formed on both the first sub-induction coil 2321 and the second sub-induction coil 2322, thereby making the first induction coil 2321 and the second sub-induction coil 2322 form a grid. In the regions where the first sub-induction coil 2321 and the second sub-induction coil 2322 intersect, and in the regions where the drive coil 231 and the induction coil 232 intersect, the light-transmitting holes on the upper and lower layers of coils are overlapped to prevent the coils from blocking the sub-pixels, which would reduce the light transmittance of the display module.

[0128] In some embodiments, the capacitive touch signal line 22 is provided with a plurality of third light-transmitting holes, each third light-transmitting hole being aligned with a corresponding sub-pixel. In the area where the electromagnetic touch coil 23 and the capacitive touch signal line 22 intersect, the second light-transmitting hole on the electromagnetic touch coil 23 is aligned with the third light-transmitting hole on the capacitive touch signal line 22 to prevent obstruction of the sub-pixel, thereby improving the light transmittance of the display module.
