[0027] Example 1 In one example, Example 1 of the present application provides a display panel.
[0028] FIG. 1 is a schematic configuration diagram of a display panel according to Example 1 of the present application, FIG. 2 is a schematic configuration diagram of a touch control layer according to Example 1 of the present application, FIG. 3 is a top schematic diagram of a capacitive touch control unit according to Example 1 of the present application, FIG. 4 is a top schematic diagram of a first touch control electrode according to Example 1 of the present application, FIG. 5 is a top schematic diagram of a second touch control electrode according to Example 1 of the present application, FIG. 6 is a top schematic diagram of a bridge electrode according to Example 1 of the present application, FIG. 7 is a top schematic diagram of an electromagnetic touch control unit according to Example 1 of the present application, FIG. 8 is a top schematic diagram of a first electromagnetic coil according to Example 1 of the present application, and FIG. 9 is a top schematic diagram of a second electromagnetic coil according to Example 1 of the present application. As shown in FIGS. 1 to 9 combined, Example 1 of the present application provides a display panel 01, the display panel 01 includes a capacitive touch control unit C0, the capacitive touch control unit C0 includes a first capacitive touch control unit C1 and a second capacitive touch control unit C2 arranged in separate layers. Here, the display panel 01 includes a plurality of electromagnetic coils M0, the plurality of electromagnetic coils M0 includes an electromagnetic touch control unit E0, the electromagnetic touch control unit E0 includes a first electromagnetic touch control unit E1 and a second electromagnetic touch control unit E2 arranged in separate layers. Here, at least one of the first electromagnetic touch control unit E1 and the second electromagnetic touch control unit E2 is arranged in the same layer as the capacitive touch control unit C1.
[0029] In the display panel 01 provided by the example of the present application, since the second electromagnetic touch control unit E2 is arranged in the same layer as the first capacitive touch control unit C1, problems such as an increase in the number of film layers and an increase in thickness of the display panel 01 caused by arranging the second electromagnetic touch control unit E2 are avoided. As a result, the display panel 01 can have a thinner thickness, the manufacturing process of the display panel 01 is simplified, and the production and manufacturing cost is reduced.
[0030] In some examples of the present application, the plurality of electromagnetic coils M0 includes the electromagnetic touch control unit E0 and the capacitive touch control unit C0.
[0031] In the related art, the electromagnetic coil M0 only includes the electromagnetic touch control unit E0, that is, the electromagnetic touch control unit E0 exists separately from the capacitive touch control unit C0.
[0032] In the display panel 01 provided by the present application, since the plurality of electromagnetic coils M0 include the electromagnetic touch control unit E0 and the capacitive touch control unit C0, a part of the electromagnetic coil M0 can be formed by using the capacitive touch control unit C0, thereby reducing the arrangement area of the electromagnetic touch control unit E0, reducing the difficulty of the process, and improving the space utilization rate of the display panel 01.
[0033] In some embodiments of the present application, the first capacitive touch control unit C1 includes a plurality of touch control electrodes C11, the second capacitive touch control unit C2 includes a plurality of bridge electrodes C21, the first electromagnetic touch control unit E1 includes a plurality of electromagnetic coil wirings E11, and the second electromagnetic touch control unit E2 includes a plurality of electromagnetic bridge wirings E21. Here, the area of the plurality of touch control electrodes C11 is larger than the area of the plurality of bridge electrodes C21, the area of the plurality of electromagnetic coil wirings E11 is larger than the area of the plurality of electromagnetic bridge wirings E21, and the electromagnetic coil wiring E11 is arranged in the same layer as the bridge electrode C21.
[0034] In the display panel 01 provided by the present application, the touch control electrode C11 belongs to the first capacitance type touch control unit C1, and the bridge electrode C21 belongs to the second capacitance type touch control unit C2. Therefore, the touch control electrode C11 and the bridge electrode C21 are arranged in different layers. Since the area of the plurality of touch control electrodes C11 is larger than the area of the plurality of bridge electrodes C21, the free area of the film layer where the plurality of bridge electrodes C21 are located is larger. The present application installs the plurality of electromagnetic coil wirings E11 with a larger area in the film layer where the plurality of bridge electrodes C21 with a larger free area are located, thereby simplifying the film layer structure of the display panel 01, reducing the thickness, and more reasonably utilizing the space in the film layer where the first capacitance type touch control unit C1 and the second capacitance type touch control unit C2 are located. Thereby, the wiring difficulty of the electromagnetic touch control unit E0 is reduced, the product yield is improved, and the production and manufacturing cost is reduced.
[0035] Specifically, the display panel 01 includes a substrate 10, a driving circuit layer 20 sequentially laminated on the substrate 10, a display function layer 30, a package layer 40, and a touch control layer 50. The touch control layer 50 includes a first insulating layer 51, a first touch control layer 52, a second insulating layer 53, and a second touch control layer 54 sequentially laminated in a direction away from the package layer 40. Here, the touch control electrode C11 in the first capacitance type touch control unit C1 is arranged in the second touch control layer 54, and the electromagnetic bridge wiring E21 in the second electromagnetic touch control unit E2 is arranged in the second touch control layer 54, that is, the electromagnetic bridge wiring E21 is arranged in the same layer as the touch control electrode C11.
[0036] In the display panel 01 provided by the present application, the electromagnetic coil wiring E11 is arranged on the same layer as the bridge electrode C21, and the electromagnetic bridge wiring E21 is arranged on the same layer as the touch control electrode C11. Thereby, the electromagnetic coil wiring E11 in the first electromagnetic touch control unit E1 shares a film layer with the bridge electrode C21 in the second capacitive touch control unit C2, and the electromagnetic bridge wiring E21 in the second electromagnetic touch control unit E2 can share a film layer with the touch control electrode C11 in the first capacitive touch control unit C1. As a result, the electromagnetic touch control unit E0 can share the space of the capacitive touch control unit C0 and the touch control layer 50, and the arrangement of the electromagnetic touch control unit E0 does not increase the number of film layers of the display panel 01, and the display panel 01 has the advantages of being thinned and the production manufacturing process being simplified.
[0037] Of course, the present application does not limit the vertical positional relationship between the first touch control layer 52 and the second touch control layer 54. For example, in another embodiment of the present application, the first touch control layer 52 may be arranged on the side opposite to the package layer 40 of the second touch control layer 54.
[0038] In some embodiments of the present application, the plurality of touch control electrodes C11 include a plurality of first touch control electrodes C111 and a plurality of second touch control electrodes C112. Each of the first touch control electrodes C111 includes a plurality of first touch control sub - electrodes C1111 sequentially arranged in the first direction X. Two adjacent first touch control sub - electrodes C1111 are electrically connected. The second touch control electrode C112 includes a plurality of second touch control sub - electrodes C1121 sequentially arranged in the second direction Y. Two adjacent second touch control sub - electrodes C1121 are electrically connected by the bridge electrode C21. The plurality of electromagnetic coils M0 include a plurality of first electromagnetic coils M1 and a plurality of second electromagnetic coils M2. Here, each first electromagnetic coil M1 includes a first main body portion M11 extending along two first directions X. Among them, one first main body portion M11 includes an electromagnetic coil wiring E11, and the other first main body portion M11 includes the first touch control electrode C111. Each second electromagnetic coil M2 includes a second main body portion M21 extending along two second directions Y. Among them, one second main body portion M21 includes an electromagnetic coil wiring E11, and the other second main body portion M21 includes the second touch control electrode C112. Here, the first direction X is orthogonal to the second direction Y.
[0039] In the display panel 01 provided by the present application, one first main body portion M11 of the first electromagnetic coil M1 includes the first touch control electrode C111, and one second main body portion M21 of the second electromagnetic coil M2 includes the second touch control electrode C112. That is, the first touch control electrode C111 and the second touch control electrode C112 can be used not only as a capacitive touch control channel but also as an electromagnetic touch control channel. Therefore, the driving of electromagnetic touch control and the driving of capacitive touch control can be realized by using one touch control driving chip, improving the integration degree of the display panel 01 and simplifying the structure of the display panel 01. Also, since each touch control channel corresponds to a pin in one touch control driving chip, the number of pins can be reduced, and the frame of the display panel 01 can be made narrower.
[0040] Note that this application does not limit the directions of the first direction X and the second direction Y. In other embodiments of this application, the directions of the first direction X and the second direction Y can be interchanged.
[0041] In some embodiments of this application, the orthographic projection of the electromagnetic bridge wiring E21 in the third direction Z does not overlap with the orthographic projection of the bridge electrode C21 in the third direction Z. Here, the third direction Z is orthogonal to the first direction X and the second direction Y.
[0042] In the display panel 01 provided by this application, the electromagnetic bridge wiring E21 is located in the second touch control layer 54. The electromagnetic bridge wiring E21 is electrically connected to the electromagnetic coil wiring E11 of the first touch control layer 52 by means of via connection. Since the bridge electrode C21 is also located in the first touch control layer 52, this application can effectively avoid the short - circuit phenomenon between the bridge electrode C21 and the electromagnetic bridge wiring E21 by an arrangement method in which the orthographic projection of the electromagnetic bridge wiring E21 in the third direction Z does not overlap with the orthographic projection of the bridge electrode C21 in the third direction Z, and can improve the touch control performance of the display panel 01.
[0043] Furthermore, the electromagnetic bridge wiring E21 and the touch control electrode C11 are arranged offset in the second touch control layer 54, and the electromagnetic coil wiring E11 and the bridge electrode C21 are arranged offset in the first touch control layer 52.
[0044] In some embodiments of this application, the area surrounded by each first electromagnetic coil M1 partially overlaps with the area surrounded by at least one of the first electromagnetic coils M1. The area surrounded by each second electromagnetic coil M2 partially overlaps with the area surrounded by at least one of the second electromagnetic coils M2.
[0045] In the display panel 01 provided by the present application, the area surrounded by each of the first electromagnetic coils M1 partially overlaps with the area surrounded by at least one of the first electromagnetic coils M1, and the area surrounded by each of the second electromagnetic coils M2 partially overlaps with the area surrounded by at least one of the second electromagnetic coils M2. Therefore, the amount of electromagnetic signal in the area surrounded by the electromagnetic coil M0 can be increased, and the sensitivity and accuracy of electromagnetic induction of the display panel 01 can be improved.
[0046] In some embodiments of the present application, each first electromagnetic coil M1 further includes a first connection portion M12 connecting the two first main body portions M11, and each second electromagnetic coil M2 further includes a second connection portion M22 connecting the two second main body portions M21. Here, the display panel 01 includes a plurality of data lines, the first main body portion M11 or the second main body portion M21 is parallel to the data line. When the first main body portion M11 is parallel to the data line, at least one of the second connection portions M22 is disposed on each side of the data line. When the second main body portion M21 is parallel to the data line, at least one of the first connection portions M12 is disposed on each side of the data line.
[0047] Specifically, the display panel 01 provided by the present application further includes, for example, a driving chip for touch control disposed at an end of the data line. The driving chip for touch control is disposed at the end of the data line, and the ends of each electromagnetic coil M0 are all electrically connected to the driving chip for touch control. Therefore, the electromagnetic coil M0 where the second connection portion M22 or the first connection portion M12 disposed on one side of the data line is located needs to be wound in order to finally be connected to the driving chip for touch control. Therefore, when the second connection portion M22 or the first connection portion M12 are both disposed on the same side of the data line, the wiring becomes dense on that side, and it may be difficult to perform wiring. The present application arranges at least one of the second connection portions M22 on both sides of the data line, or arranges at least one of the first connection portions M12 on both sides of the data line, so as to equalize the number of winding lines on both sides of the data line and reduce the difficulty of wiring.
[0048] In some embodiments of the present application, the type of the display panel 01 may be an OLED display panel, a liquid crystal display panel, an LED display panel, or the like.
[0049] In another example, the present application provides a driving method for the display panel 01. The driving method of the display panel 01 includes scanning the capacitive touch control unit C0 in the display panel 01 using a driving chip. Each scanning cycle includes an electromagnetic scanning section and a capacitance scanning section. Here, in the electromagnetic scanning section, the capacitive touch control unit C0 operates with an electromagnetic touch control function, and in the capacitance scanning section, the capacitive touch control unit C0 operates with a capacitance touch control function.
[0050] By dividing each scanning cycle into an independent electromagnetic scanning section and a capacitance scanning section, the present application can use the capacitive touch control unit C0 as an electromagnetic touch control channel in the electromagnetic scanning section and as a capacitance touch control channel in the capacitance scanning section in a time-division driving manner.
[0051] In a further example, Embodiment 1 of the present application further provides a display device, which includes a housing and any one of the above display panels 01. Here, the housing has an accommodation space, and the display panel 01 is disposed within the accommodation space.
[0052] Embodiment 2 FIG. 10 is a schematic configuration diagram of a touch control layer according to Embodiment 2 of the present application. As shown in combination with FIGS. 1, 3 to 10, Embodiment 2 of the present application provides a display panel 01, a driving method, and a display device. The display panel 01 includes a capacitive touch control unit C0. The capacitive touch control unit C0 includes a first capacitive touch control unit C1 and a second capacitive touch control unit C2 arranged in separate layers. Here, the display panel 01 includes a plurality of electromagnetic coils M0. The plurality of electromagnetic coils M0 includes an electromagnetic touch control unit E0. The electromagnetic touch control unit E0 includes a first electromagnetic touch control unit E1 and a second electromagnetic touch control unit E2 arranged in separate layers. Here, the plurality of electromagnetic coils M0 further includes the capacitive touch control unit C0. The electromagnetic coil wiring E11 is arranged in the same layer as the bridge electrode C21.
[0053] In the display panel 01 provided by the embodiment of the present application, since the electromagnetic coil wiring E11 is arranged in the same layer as the bridge electrode C21, problems such as an increase in the number of film layers and an increase in thickness of the display panel 01 caused by arranging the electromagnetic coil wiring E11 are avoided. As a result, the manufacturing process of the display panel 01 is simplified and the production and manufacturing costs are reduced.
[0054] It should be noted that the configuration and driving method of the display panel 01 and the display device according to Embodiment 2 of the present application are similar to those of the display panel 01, the display device, and the driving method according to Embodiment 1 of the present application. Embodiment 2 of the present application does not describe the configuration and its effects of the same part.
[0055] The difference is that the electromagnetic bridge wiring E21 is arranged in separate layers from the touch control electrode C11 and the bridge electrode C21, respectively. That is, the electromagnetic bridge wiring E21 is arranged in a film layer excluding the film layers where the touch control electrode C11 and the bridge electrode C21 are located.
[0056] Specifically, the display panel 01 includes a substrate 10, a driving circuit layer 20 sequentially stacked on the substrate 10, a display function layer 30, a package layer 40, and a touch control layer 50, and the electromagnetic touch control unit E0E is disposed in the touch control layer 50. The touch control layer 50 includes a third insulating layer 55, a third touch control layer 56, a first insulating layer 51, a first touch control layer 52, a second insulating layer 53, and a second touch control layer 54 sequentially stacked in a direction away from the package layer 40. Here, the plurality of bridge electrodes C21 and the plurality of electromagnetic coil wirings E11 are both disposed in the first touch control layer 52, the plurality of touch control electrodes C11 are disposed in the second touch control layer 54, and the electromagnetic bridge wiring E21 is disposed in the third touch control layer 56.
[0057] Since the arrangement area of the plurality of touch control electrodes C11 is large and relatively dense, when the plurality of touch control electrodes C11 and the electromagnetic bridge wiring E21 are arranged in the same layer, the difficulty of wiring design increases. In the present application, by arranging the electromagnetic bridge wiring E21 in the third touch control layer 56, the wiring difficulty can be effectively reduced, and the production yield of the display panel 01 can be improved.
[0058] Example 3 FIG. 11 is a schematic configuration diagram of a touch control layer according to Embodiment 3 of the present application. As shown in combination with FIGS. 1, 3 to 9, and FIG. 11, Embodiment 3 of the present application provides a display panel 01, a driving method, and a display device. The display panel 01 includes a capacitive touch control unit C0. The capacitive touch control unit C0 includes a first capacitive touch control unit C1 and a second capacitive touch control unit C2 arranged in separate layers. Here, the display panel 01 includes a plurality of electromagnetic coils M0. The plurality of electromagnetic coils M0 includes an electromagnetic touch control unit E0. The electromagnetic touch control unit E0 includes a first electromagnetic touch control unit E1 and a second electromagnetic touch control unit E2 arranged in separate layers. Here, the plurality of electromagnetic coils M0 further includes the capacitive touch control unit C0. The electromagnetic coil wiring E11 is arranged in the same layer as the bridge electrode C21. The electromagnetic bridge wiring E21 is arranged in a separate layer from the touch control electrode C11 and the bridge electrode C21.
[0059] In the display panel 01 provided by the embodiment of the present application, since the electromagnetic coil wiring E11 is arranged in the same layer as the bridge electrode C21, problems such as an increase in the number of film layers and an increase in thickness of the display panel 01 due to the arrangement of the electromagnetic coil wiring E11 are avoided. As a result, the manufacturing process of the display panel 01 is simplified, and the production and manufacturing costs are reduced. Since the electromagnetic bridge wiring E21 is arranged in a separate layer from the touch control electrode C11 and the bridge electrode C21, the wiring difficulty can be effectively reduced, and the production yield of the display panel 01 can be improved.
[0060] It should be noted that the configuration and driving method of the display panel 01 and the display device according to Embodiment 3 of the present application are similar to those of the display panel 01, the display device, and the driving method according to Embodiment 2 of the present application. Embodiment 3 of the present application does not describe the configuration and its effects of the same parts.
[0061] The difference is that the second electromagnetic touch control unit E2 further includes a parallel connection structure E22 of a plurality of electromagnetic coils. The parallel connection structure E22 of the electromagnetic coils is connected in parallel with the electromagnetic coil wiring E11.
[0062] In the display panel 01 provided by the embodiment of the present application, the second electromagnetic touch control unit E2 further includes a parallel connection structure E22 of a plurality of electromagnetic coils. Since the parallel connection structure E22 of the electromagnetic coils is arranged on the same layer as the electromagnetic bridge wiring E21, arranging the parallel connection structure E22 of the electromagnetic coils does not cause an increase in the number of film layers of the display panel 01. Further, the parallel connection structure E22 of the electromagnetic coils is connected in parallel with the electromagnetic coil wiring E11, whereby the resistance of the electromagnetic coil wiring E11 is reduced, the impedance when an electromagnetic signal is transmitted through the electromagnetic touch control unit E0 is reduced, and the accuracy of the electromagnetic signal can be improved.

Here, at least one of the first electromagnetic touch control unit E1 and the second electromagnetic touch control unit E2 is arranged on the same layer as the capacitive touch control unit C0.
[0064] It should be noted that the configurations of the display panel 01 and the display device according to Embodiment 4 of the present application are similar to the configurations of the display panel 01 and the display device according to Embodiment 1 of the present application. Embodiment 4 of the present application does not describe the configurations and their effects of the same parts.
[0065] The difference is that the plurality of electromagnetic coils M0 do not include the capacitive touch control unit C0.
[0066] In the display panel 01 provided by the embodiment of the present application, since the plurality of electromagnetic coils M0 do not include the capacitive touch control unit C0, the capacitive touch control unit C0 is arranged independently of the electromagnetic touch control unit E0. The electromagnetic touch control unit E0 only has a touch control function and does not contribute to the formation of the electromagnetic coil M0, and there is no mutual influence between the capacitive touch control function and the electromagnetic touch control function of the display panel 01.
[0067] Referring to FIG. 12, when the electromagnetic bridge wiring E21 is arranged in the same layer as the bridge electrode C21, the electromagnetic coil wiring E11 is arranged in a different layer from the touch control electrode C11 and the bridge electrode C21. Referring to FIG. 13, when the electromagnetic coil wiring E11 is arranged in the same layer as the bridge electrode C21, the electromagnetic bridge wiring E21 is arranged in a different layer from the touch control electrode C11 and the bridge electrode C21.

By arranging at least one of the first electromagnetic touch control unit and the second electromagnetic touch control unit in the same layer as the capacitive touch control unit, the present application can form a part of the structure in the electromagnetic touch control unit by using the space of the film layer where the capacitive touch control unit is located, and improves the problems of the display panel having an electromagnetic touch control function, being overall thick, and having a complicated production process.
