[0103] Referring to FIG. 1 and FIG. 2, the display panel includes signal lines, which include a data signal line DATA and other signal lines required to ensure normal operation of the display panel, such as a power signal line, a scanning signal line, and a touch signal line, and the like. Optionally, referring to FIG. 1, the display panel can further include a pixel circuit 20 and a light emitting element 30, the signal lines are electrically connected to the pixel circuit 20 and are configured to provide a voltage signal and / or a current signal to the pixel circuit 20; the pixel circuit 20 is electrically connected to the light emitting element 30 and is configured to drive the light emitting element 30 to emit light under the action of the voltage signal and / or the current signal. Optionally, the pixel circuit 20 can be configured in various ways, and the pixel circuit can be "2T1C", "7T1C", or "8T1C", wherein "T" represents a transistor, and "C" represents a storage capacitor. The specific configuration of the pixel circuit is not limited in the embodiments of the present application, for example, "3T1C" and "6T1C" pixel circuits are also within the scope of the technical solutions protected by the embodiments of the present application. The light emitting element 30 can be at least one of a light emitting diode, an organic light emitting diode, and a micro light emitting diode, and the specific form of the light emitting element 30 is also not limited in the embodiments of the present application.
[0104] Continuing to refer to FIG. 1 and FIG. 2, the display panel provided by the embodiments of the present application includes a display area AA and a non-display area NAA, the data signal line DATA, the pixel circuit 20, and the light emitting element 30 described above can be disposed in the display area AA, and the non-display area NAA includes a plurality of demultiplexing unit setting areas NAA1. The plurality of demultiplexing unit setting areas NAA1 are provided with a plurality of demultiplexing units DEMUX and at least two switch control lines SW; the demultiplexing unit DEMUX includes at least two demultiplexing switches K; the input ends S of the at least two demultiplexing switches K in the same demultiplexing unit DEMUX are connected, the output ends D of the at least two demultiplexing switches K are respectively electrically connected to different data signal lines DATA, and the control ends G of the at least two demultiplexing switches are respectively electrically connected to different switch control lines SW. The demultiplexing unit K is used to transmit the signal input from the input end S to the data signal line DATA through the output end D under the action of the control signal in the switch control line SW, and the enable phases of the control signals in the different switch control signal lines SW are staggered to ensure that the at least two demultiplexing switches K of the same demultiplexing unit DEMUX are turned on at different times. That is, the same demultiplexing unit DEMUX can time-divisionally distribute the input signal transmitted by the same signal output terminal to any one of the plurality of data signal lines DATA, so as to reduce the number of signal output terminals under the premise of realizing normal output of the data signal, and reduce the difficulty of layout of the signal output terminals in the display panel.
[0105] Optionally, the display area AA further comprises a first display area AA1 and a second display area AA2. The second display area AA2 is located on both sides of the first display area AA1 along the second direction Y, as exemplarily shown in FIG. 2, but is not limited thereto. In this arrangement, along the orientation shown in FIG. 2, the second display area AA2 is located between the first display area AA1 and the non-display areas NAA on the left and right sides, along the second direction Y, the first display area AA1 is closer to the center of the display panel, and the second display area AA2 is closer to the edge of the display panel. The data signal line DATA located in the second display area is electrically connected to the output end D of the demultiplexing switch K through the data connection trace FIAA. At least part of the data connection trace FIAA is located in the display area AA, and at least part of the data connection trace FIAA is located in the first display area AA1. In this way, the demultiplexing unit DEMUX connected to the data signal line DATA and the data connection trace FIAA can be more concentrated below the first display area AA1. In this way, the connection line when the data signal line DATA and the data connection trace FIAA are connected to the demultiplexing switch K occupies less space in the first direction, which is beneficial to reducing the occupied space of the non-display area, improving the display area ratio of the display panel, and improving the screen-to-body ratio of the display panel.
[0106] Exemplarily, FIG. 3 takes the example of the demultiplexing unit DEMUX including two demultiplexing switches K1 and K2. Correspondingly, the display panel includes two switch control lines SW1 and SW2, the control end of the demultiplexing switch K1 is electrically connected with the switch control line SW1, the control end of the demultiplexing switch K2 is electrically connected with the switch control line SW2, and the switch control lines SW1 and SW2 time-divisionally transmit the enable signals of the demultiplexing switches. When the enable signal is transmitted in the switch control line SW1, the demultiplexing switch K1 is turned on, and the demultiplexing switch K1 is used to transmit the data signal inputted by the input end to the data signal line DATA directly or to the data signal line connected with it through the data connection wire FIAA; at this time, the non-enable signal is transmitted in the switch control line SW2, and the data signal line DATA or the data connection wire FIAA connected with the demultiplexing switch K2 is in the state of potential floating. Similarly, when the enable signal is transmitted in the switch control line SW2, the demultiplexing switch K2 is turned on, and the demultiplexing switch K2 is used to transmit the data signal inputted by the input end to the data signal line DATA directly or to the data signal line connected with it through the data connection wire FIAA; at this time, the non-enable signal is transmitted in the switch control line SW1, and the data signal line DATA or the data connection wire FIAA connected with the demultiplexing switch K1 is in the state of potential floating. As shown in FIGS. 2 and 3, since the data signal line DATA and the first wire part FIAA1 have a small distance in the second direction, when the data signal line DATA or the first wire part FIAA1 is in the state of potential floating, it is easy to be coupled with the first wire part FIAA1 or the data signal line DATA adjacent to it and then to pull down or pull up the signal on it, resulting in display abnormality. Based on this, the data signal line DATA in the embodiment of the application includes the first data signal line DATA1, which can be understood as the data signal line corresponding to the first wire part FIAA1 arranged in correspondence therewith. The corresponding arrangement here can be understood as that the distance between the first data signal line DATA1 and the first wire part FIAA1 arranged in correspondence therewith in the second direction is smaller than the distance between the first data signal line DATA1 and any other first wire part FIAA1 in the second direction, and the distance between the first data signal line DATA1 and the first wire part FIAA1 arranged in correspondence therewith in the second direction is smaller than the distance between the first data signal line DATA1 and any other data signal line DATA in the second direction, that is, the first data signal line DATA1 and the first wire part FIAA1 arranged in correspondence therewith are the closest transmission data signal wires.Or it can also be understood that the data signal is transmitted, and the distance between the first data signal line DATA1 and the nearest first trace part FIAA1 is the reference distance, the data signal line DATA and the first trace part FIAA1 meeting the reference distance are the corresponding first data signal line DATA1 and the first trace part FIAA1, and the data signal line DATA and the first trace part FIAA1 greater than the reference distance do not meet the corresponding setting defined in the embodiment of the application. The control ends of the two multiplexing switches K connected with the corresponding first data signal line DATA and the first trace part FIAA1 are connected with the same switch control signal, that is, the two multiplexing switches K connected with the corresponding first data signal line DATA and the first trace part FIAA1 are turned on or turned off at the same time, so that the corresponding first data signal line DATA1 and the first trace part FIAA1 can write data signals at the same time, and there will be no case that one of them is floating and the other is coupled with other signals, which ensures the high accuracy of the data signal in the corresponding first data signal line DATA1 and the first trace part FIAA1 and ensures good display effect.
[0107] For example, as shown in FIG. 3, the multiplexing switch connected with the switch control signal line SW1 is recorded as K1, and the multiplexing switch connected with the switch control signal line SW2 is recorded as K2. The control ends of the multiplexing switch K2 in the first group of multiplexing units and the multiplexing switch K2 in the second group of multiplexing units are both electrically connected with the switch control signal line SW2. The first data signal line and the first trace part connected with the two multiplexing switches K2 can be a group of corresponding first data signal lines DATA1 and first trace parts FIAA1. The two multiplexing switches K2 are turned on at the same time, the first data signal line DATA1 and the first trace part FIAA1 connected therewith write data signals at the same time, and the coupling interference of the data signals transmitted in the first data signal line DATA1 and the first trace part FIAA1 is small. For another example, the control ends of the multiplexing switch K1 in the second group of multiplexing units and the multiplexing switch K1 in the third group of multiplexing units are both electrically connected with the switch control signal line SW1. The first data signal line and the first trace part connected with the two multiplexing switches K1 can be a group of corresponding first data signal lines DATA1 and first trace parts FIAA1. The two multiplexing switches K1 are turned on at the same time, the first data signal line DATA1 and the first trace part FIAA1 connected therewith write data signals at the same time, and the coupling interference of the data signals transmitted in the first data signal line DATA1 and the first trace part FIAA1 is small.
[0108] In summary, the display panel provided by the embodiment of the present application is characterized in that the data signal lines in the first display area are directly electrically connected with the output ends of the multi-way distribution switch, the data signal lines in the second display area are electrically connected with the output ends of the multi-way distribution switch through the data connection traces, and at least part of the data connection traces is located in the display area. In this way, the data signal lines in the second display area can be prevented from being directly electrically connected with the output ends of the multi-way distribution switch, and the area of the non-display area can be prevented from being increased due to the direct electrical connection between the data signal lines in the second display area and the output ends of the multi-way distribution switch, thereby improving the screen-to-body ratio of the display panel. Optionally, the data connection traces include first trace parts, the first trace parts and the data signal lines both extend along the first direction, and there are first data signal lines corresponding to the first trace parts. The distance between the first data signal line and the first trace part corresponding to the first data signal line is smaller than the distance between the first data signal line and any other first trace part, and smaller than the distance between the first data signal line and any other data signal line. The control ends of the multi-way distribution switches connected with the corresponding data signal lines and the first trace parts are connected with the same switch control signal, so that the corresponding data signal lines and the first trace parts are simultaneously written with data signals, and are not coupled with other signals due to the floating potential of a certain signal line, thereby ensuring high data signal accuracy. Optionally, the first data signal lines and the first trace parts corresponding to the first data signal lines are connected with the control ends of two multi-way distribution switches, and the control ends of the two multi-way distribution switches are connected with the same switch control signal. That is, the first data signal lines and the first trace parts corresponding to the first data signal lines simultaneously input data signals, so as to avoid that a signal line with floating potential is coupled and disturbed when the two signal lines do not simultaneously input data signals. In this way, the data signal accuracy of the first data signal lines and the first trace parts corresponding to the first data signal lines can be ensured to be high, and the display effect of the display panel can be ensured to be good.
[0109] Optionally, continuing to refer to FIG. 2, in the display panel provided by the embodiment of the present application, the data connection traces can further include second trace parts FIAA2, which are respectively electrically connected with the first trace parts FIAA1 and the data signal lines DATA in the second display area AA2, and are used to transmit data signals from the first trace parts FIAA1 to the data signal lines DATA in the second display area AA2. Optionally, the second trace parts FIAA2 and the first trace parts FIAA1 can be arranged on the same layer or different layers, and the embodiment of the present application does not limit this.
[0110] Optionally, the signal line can further include a virtual data connection trace L0, which is insulated from the data connection trace FIAA. The virtual data connection trace L0 can balance the wiring density of the film layer where the data connection trace FIAA is located at different positions of the display area, ensure that the wiring density of different areas of the display area is the same or similar, and ensure that the flatness and optical properties of different areas of the display area are good. Specifically, the virtual data connection trace L0 can include a first virtual trace portion L01 and a second virtual trace portion L02. The first virtual trace portion L01 extends along a first direction, and the second virtual trace portion L02 extends along a second direction. The first virtual trace portion L01 is in the same layer and insulated from the first trace portion FIAA1, and the second virtual trace portion L02 is in the same layer and insulated from the second trace portion FIAA2. The wiring density in the first direction is balanced by the first virtual trace portion L01, and the wiring density in the second direction is balanced by the second virtual trace portion L02, so as to ensure that the film layer where the data connection trace FIAA is located has balanced wiring density in different areas of the display area.
[0111] Optionally, the virtual data connection trace L0 can be electrically connected to the fixed potential signal line. On the one hand, it can reduce the resistance of the fixed potential signal line, and solve the problem of precision decline caused by transmission loss in the transmission process of the low fixed potential signal. On the other hand, the electrical connection of the virtual data connection trace L0 and the fixed potential signal line can also avoid the influence of other signals on the actual due to the floating coupling of the virtual data connection trace L0, and ensure the display effect of the display panel.

Optionally, the data signal lines DATA and the first wiring section FIAA1 can be arranged in the same layer, and in order to match the arrangement positions of different transistors in the pixel circuit, the first wiring section FIAA1 can be arranged in the data signal line group 40 in which the first data signal line DATA1 corresponding to the first wiring section FIAA1 is arranged, so as to satisfy the electrical connection relationship between the data signal line DATA and the corresponding data writing transistor. It should be noted that FIGS. 20-41 and 69-79 all take an example in which each data signal line group 40 includes two data signal lines DATA, and the number of data signal lines DATA included in each data signal line group 40 is not limited in the embodiments of the present application.
[0127] Optionally, continuing to refer to FIGS. 4-41, the display panel further comprises a plurality of data signal line groups 40, each data signal line group 40 comprising a plurality of data signal lines DATA, the plurality of data signal lines DATA in the same data signal line group 40 being electrically connected to the output ends D of the plurality of demultiplexing switches K in the same demultiplexing unit DEMUX; the display panel further comprises a plurality of first trace segment groups 50, each first trace segment group 50 comprising a plurality of first trace segments FIAA1, the plurality of first trace segments FIAA1 in the same first trace segment group 50 being electrically connected to the output ends D of the plurality of demultiplexing switches K in the same demultiplexing unit DEMUX; each data signal line group 40 comprises at least one first data signal line DATA1.
[0128] For example, the plurality of data signal lines DATA in the same data signal line group 40 are electrically connected to the output ends D of the plurality of demultiplexing switches K in the same demultiplexing unit DEMUX, so that the plurality of data signal lines DATA in each data signal line group 40 input data signals in time under the control of the demultiplexing unit DEMUX. The plurality of first trace segments FIAA1 in the same first trace segment group 50 are electrically connected to the output ends D of the plurality of demultiplexing switches K in the same demultiplexing unit DEMUX, so that the plurality of first trace segments FIAA1 in each first trace segment group 50 input data signals in time under the control of the demultiplexing unit DEMUX. Optionally, each data signal line group 40 comprises at least one first data signal line DATA1, that is, there is at least one data signal line in each data signal line group 40 that has a corresponding first trace segment FIAA1 arranged therewith, so that the data signal line is not interfered by the first trace segment FIAA1 arranged in close proximity thereto when the potential of the first trace segment FIAA1 is floating, and does not interfere with the signal in the first trace segment FIAA1 arranged in close proximity thereto when the potential of the first trace segment FIAA1 is floating, ensuring the accuracy of the data signal during transmission.
[0129] For example, in the embodiments shown in FIGS. 4-19, each data signal line group 40 includes two data signal lines DATA, for example, the two data signal lines DATA can include two first data signal lines DATA1, so that each data signal line DATA in the data signal line group 40 will not be greatly disturbed by the first trace section FIAA1 disposed in close proximity thereto when the potential is floating, and will also not greatly disturb the data signal in the first trace section FIAA1 disposed in close proximity thereto, ensuring the accuracy during data signal transmission. In the embodiments shown in FIGS. 20-41, each data signal line group 40 includes two data signal lines DATA, for example, the two data signal lines DATA include one first data signal line DATA1, so that one data signal line DATA in the data signal line group 40 will not be greatly disturbed by the first trace section FIAA1 disposed in close proximity thereto when the potential is floating, and will also not greatly disturb the data signal in the first trace section FIAA1 disposed in close proximity thereto, ensuring the accuracy during data signal transmission. Moreover, when each data signal line group 40 includes one first data signal line DATA1, the signal access mode of the control end of the multiplexing switch electrically connected to the data signal line DATA in the data signal line group 40 is higher in degree of freedom, and the control logic of the multiplexing switch is simpler and more efficient.
[0130] On the basis of the above embodiments, continuing to refer to FIGS. 4-41, at least two first data signal lines DATA1 corresponding to at least two first trace sections FIAA1 in the same first trace section group 50 are disposed in at least two data signal line groups 40 disposed adjacent along the second direction.
[0131] Referring to FIGS. 4-41, at least two first trace sections FIAA1 in the same first trace section group 50 can be a first sub-trace section FIAA11 and a second sub-trace section FIAA12, respectively. For example, in the position shown in the figure, the first sub-trace section FIAA11 is located on the left side of the second sub-trace section FIAA12 in the same first trace section group 50, and the first data signal line DATA1 corresponding to the first sub-trace section FIAA11 is also located on the left side of the second sub-trace section FIAA12. The second sub-trace section FIAA12 is located on the right side of the first sub-trace section FIAA11, and the first data signal line DATA1 corresponding to the second sub-trace section FIAA12 is also located on the right side of the first sub-trace section FIAA12. Compared with the scheme in which the at least two first data signal lines DATA1 corresponding to the at least two first trace sections FIAA1 in the same first trace section group 50 are located in the same data signal line group 40, the problem of lengthening the line when the first data signal line DATA1 is electrically connected to the multi-way distribution switch can be avoided, the wiring difficulty when the first data signal line DATA1 is electrically connected to the multi-way distribution switch is reduced, and the correspondence difficulty of the first trace section FIAA1 and the first data signal line DATA1 is simplified.
[0132] On the basis of the above-mentioned embodiments, with continued reference to FIGS. 4-19, each data signal line group 40 includes at least two first data signal lines DATA1; and at least two first trace sections FIAA1 corresponding to the at least two first data signal lines DATA1 in the same data signal line group 40 are electrically connected to the output ends of the multi-way distribution switches in different multi-way distribution units DEMUX.
[0133] For example, at least two first data signal lines DATA1 in the same data signal line group 40 can be a first sub-data signal line DATA11 and a second sub-data signal line DATA12, respectively. For example, in the position shown in FIG. 16, in the same data signal line group 40, the first sub-data signal line DATA11 is located on the right side of the second sub-data signal line DATA12, and the first trace part FIAA1 corresponding to the first sub-data signal line DATA11 is also located on the right side of the second sub-data signal line DATA12; the second sub-data signal line DATA12 is located on the left side of the first sub-data signal line DATA11, and the first trace part FIAA1 corresponding to the second sub-data signal line DATA12 is also located on the left side of the first sub-data signal line DATA11. Compared with the scheme that the at least two first trace parts FIAA1 corresponding to the at least two first data signal lines DATA1 in the same data signal line group 40 are located in the same first trace part group 50, the problem of lengthening the line when the first trace part FIAA1 is electrically connected with the multi-way distribution switch can be avoided, the wiring difficulty when the first trace part FIAA1 is electrically connected with the multi-way distribution switch is reduced, and the correspondence difficulty of the first trace part FIAA1 and the first data signal line DATA1 is simplified.
[0134] In summary, the above embodiments describe the correspondence setting mode between the data signal line and the first trace part. On the basis of the above embodiments, with reference to FIGS. 20-41, 58-68, and 69-79, the display panel provided by the embodiments of the present application can further include an auxiliary connection line 60, the auxiliary connection line 60 extends along the first direction, and the auxiliary connection line is arranged in the same layer as the first trace part FIAA1.
[0135] For example, referring to FIGS. 20-41, 58-68 and 69-79, the display panel provided by the embodiments of the present application further comprises an auxiliary connection line 60, which is arranged in the same layer as the first trace part FIAA1, for example, in the second source-drain electrode layer or in the third source-drain metal layer. In one aspect, the auxiliary connection line 60 can serve as an isolation line between different data signal lines, for example, between data signal lines, between data signal lines and the first trace part, or between first trace parts, to avoid coupling interference between different signal lines. In another aspect, the auxiliary connection line 60 can balance the wiring density in different areas. For example, referring to FIGS. 20-41 and 69-79, at least part of the auxiliary connection line 60 and at least part of the first trace part FIAA1 can be symmetrically arranged about a virtual axis, to avoid differences in flatness in different areas of the panel due to different wiring densities, thereby affecting the preparation of subsequent film layers and the uniformity of the overall light transmission effect.
[0136] Optionally, continuing to refer to FIGS. 20-41, each data signal line group 40 comprises a first data signal line DATA1; each data signal line group 40 further comprises a second data signal line DATA2; the display panel further comprises a second virtual axis X2 extending in the first direction; at least part of the first data signal line DATA1 and at least part of the second data signal line DATA2 are symmetric about the second virtual axis X2; at least part of the first trace part FIAA1 and at least part of the auxiliary connection line 60 are symmetric about the second virtual axis X2.
[0137] For example, referring to FIGS. 20-41, each data signal line group 40 includes a first data signal line DATA1, that is, a data signal line in each data signal line group 40, and part of the data signal lines, that is, the first data signal line DATA1, has a first routing section FIAA1 arranged thereon; part of the data signal lines, that is, the second data signal line DATA2, does not have a first routing section FIAA1 arranged thereon. In terms of routing density, the first data signal line DATA1 has a first routing section FIAA1 arranged thereon, while the second data signal line DATA2 does not have a first routing section FIAA1 arranged thereon, and thus the first data signal line DATA1 and the second data signal line DATA2 have an uneven routing density. In the embodiments of the present application, at least part of the first data signal line DATA1 and at least part of the second data signal line DATA2 are symmetrical about the second virtual axis X2, and at least part of the first routing section FIAA1 and at least part of the auxiliary connection line 60 are symmetrical about the second virtual axis X2, that is, in terms of routing density, the auxiliary connection line 60 and the first routing section FIAA1 have the same or similar routing positions, and thus the first data signal line DATA1 and the second data signal line DATA2 have the same or similar routing densities, and the same data signal line group has the same or similar routing densities around different data signal lines, and thus the display panel has good flatness and optical properties due to the balanced routing density.
[0138] On the basis of the above embodiments, the first routing section is arranged on the side of the first data signal line away from the auxiliary connection line, and the auxiliary connection line is arranged on the side of the second data signal line away from the first routing section, that is, the first routing section and the auxiliary connection line are arranged on the two sides of the same data signal line group, that is, outside the data signal line group. Such an arrangement is used to match the arrangement of the transistors in the pixel circuit, to ensure the electrical connection between the data signal line and the data writing transistor, and is also conducive to the routing density of the same data signal line group, for example, in the second display area where no data connection routing is arranged, the good routing density of the data signal line can compress the space, so as to leave space for arranging more data signal line groups and pixel circuits, and thus the display resolution of the display panel is improved.
[0139] Optionally, continuing to refer to FIGS. 20-41, the first trace portion FIAA1 is located on one side of the first data signal line DATA1 close to the auxiliary connection line 60, and the auxiliary connection line 60 is located on one side of the second data signal line DATA2 close to the first trace portion FIAA1, that is, the first trace portion FIAA1 and the auxiliary connection line 60 are located in the same data signal line group, respectively. In this way, on the one hand, it is used to match the arrangement of the transistors in the pixel circuit, to ensure the electrical connection relationship between the data signal line DATA and the data writing transistor, and on the other hand, the auxiliary connection line 60 can serve as a physical isolation line between the first trace portion FIAA1 and the second data signal line DATA2, to reduce the mutual interference between the signals in the first trace portion FIAA1 and the second data signal line DATA2, and to ensure the independence and stability of the signals in the first trace portion FIAA1 and the second data signal line DATA2. At the same time, the auxiliary connection line 60 can also serve as a physical isolation line between the first data signal line DATA1 and the second data signal line DATA2, to reduce the mutual interference between the signals in the first data signal line DATA1 and the second data signal line DATA2, and to ensure the independence and stability of the signals in the first data signal line DATA1 and the second data signal line DATA2.
[0140] On the basis of the above embodiment, continuing to refer to FIGS. 58-68, each data signal line group 40 includes two first data signal lines DATA1; the display panel further includes a third virtual axis X3 extending along the first direction; at least part of the two first data signal lines DATA1 in the same data signal line group 40 are symmetrical about the third virtual axis X3; at least part of the two first trace portions FIAA1 corresponding to the two first data signal lines DATA1 are symmetrical about the third virtual axis X3; and the auxiliary connection line 60 and the third virtual axis X3 at least partially overlap in the orthographic projection on the substrate plane.
[0141] For example, as shown in FIGS. 58-68, at least part of the two first data signal lines DATA1 in the same data signal line group 40 are symmetric about the third virtual axis X3, at least part of the two first trace sections FIAA1 corresponding to the two first data signal lines DATA1 are symmetric about the third virtual axis X3, that is, on both sides of the third virtual axis X3, there are corresponding first data signal lines DATA1 and first trace sections FIAA1, and the control ends of the two multiplexing switches connected to the corresponding first data signal lines DATA1 and first trace sections FIAA1 are connected to the same switch control signal, which ensures that the corresponding first data signal lines DATA1 and first trace sections FIAA1 input data signals at the same time, and one of them does not float and is not disturbed by the coupling of the other, which ensures that the coupling interference between data signals is small, which is beneficial to the accurate transmission of data signals. Optionally, the orthogonal projection of the auxiliary connection line 60 on the substrate plane at least partially overlaps the orthogonal projection of the third virtual axis X3 on the substrate plane, that is, at least part of the two first data signal lines DATA1 in the same data signal line group 40 are symmetric about the auxiliary connection line 60, and at least part of the two first trace sections FIAA1 corresponding to the two first data signal lines DATA1 are symmetric about the auxiliary connection line 60, that is, on both sides of the third virtual axis X3, which can isolate the two first data signal lines DATA1 in the same data signal line group 40 that transmit data signals at different times, and isolate the two first trace sections FIAA1 that transmit data signals at different times, and isolate the first data signal lines DATA1 and the first trace sections FIAA1 that transmit data signals at different times, which reduces the coupling interference between the two signal lines that transmit data signals at different times and improves the accuracy of data signal transmission.
[0142] Optionally, the first trace section corresponding to the first data signal line is located on the side of the first data signal line close to the auxiliary connection line axis, that is, among the corresponding first data signal line and the first trace section, the first trace section is located on the side close to the auxiliary connection line, which ensures that the data signals in the two first trace sections that transmit data signals at different times can be well isolated by the auxiliary connection line.
[0143] Optionally, continuing to refer to FIGS. 58-68, the first trace section FIAA1 corresponding to the first data signal line DATA1 is located on the side of the first data signal line DATA1 away from the auxiliary connection line 60, that is, among the corresponding first data signal line DATA1 and the first trace section FIAA1, the first data signal line DATA1 is located on the side close to the auxiliary connection line 60, which ensures that the data signals in the two first data signal lines DATA1 that transmit data signals at different times can be well isolated by the auxiliary connection line.
[0144] On the basis of the above-mentioned embodiments, with continued reference to FIGS. 20-41, the auxiliary connection line 60 is electrically connected with the fixed potential signal line.
[0145] Exemplarily, the auxiliary connection line 60 is electrically connected with the fixed potential signal line, so that the fixed potential signal is transmitted in the auxiliary connection line 60, which can further isolate the mutual interference between the signal lines located on both sides of the auxiliary connection line 60, for example, isolate the coupling interference between the data signal lines, for example, isolate the coupling interference between the data signal line and the first trace part, for example, isolate the coupling interference between the first trace parts, so as to ensure to reduce the coupling interference between different signal lines and improve the signal transmission accuracy. Moreover, the auxiliary connection line 60 and the fixed potential signal line form a parallel structure, which can further reduce the loss of the signal transmitted in the fixed potential signal line in the transmission process, so as to ensure that the fixed potential signal transmission loss is small.

[0186] For example, referring to FIG. 1 and FIG. 2, the display panel includes signal lines, which include a data signal line DATA and other signal lines required for ensuring normal operation of the display panel, such as a power signal line, a scanning signal line, and a touch signal line, and the like. Optionally, referring to FIG. 1, the display panel can further include a pixel circuit 20 and a light emitting element 30, the signal lines are electrically connected to the pixel circuit 20 and are configured to provide a voltage signal and / or a current signal to the pixel circuit 20; the pixel circuit 20 is electrically connected to the light emitting element 30 and is configured to drive the light emitting element 30 to emit light under the action of the voltage signal and / or the current signal. Optionally, the pixel circuit 20 can be configured in various ways, and the pixel circuit can be "2T1C", "7T1C", or "8T1C", wherein "T" represents a transistor, and "C" represents a storage capacitor.

The light emitting element 30 can be at least one of a light emitting diode, an organic light emitting diode, and a micro light emitting diode, and the specific form of the light emitting element 30 is also not limited in the embodiments of the present application.
[0187] Continuing to refer to FIG. 1 and FIG. 2, the display panel provided by the embodiments of the present application includes a display area AA and a non-display area NAA, the data signal line DATA, the pixel circuit 20, and the light emitting element 30 described above can be disposed in the display area AA, and the non-display area NAA includes a plurality of demultiplexing unit setting areas NAA1. The plurality of demultiplexing unit setting areas NAA1 are provided with a plurality of demultiplexing units DEMUX and at least two switch control lines SW; the demultiplexing unit DEMUX includes at least two demultiplexing switches K; the input ends S of the at least two demultiplexing switches K in the same demultiplexing unit DEMUX are connected, the output ends D of the at least two demultiplexing switches K are respectively electrically connected to different data signal lines DATA, and the control ends G of the at least two demultiplexing switches are respectively electrically connected to different switch control lines SW. The demultiplexing unit K is used to transmit the signal input from the input end S to the data signal line DATA through the output end D under the action of the control signal in the switch control line SW, and the enable phases of the control signals in the different switch control signal lines SW are staggered to ensure that the at least two demultiplexing switches K in the same demultiplexing unit DEMUX are turned on at different times. That is, the same demultiplexing unit DEMUX can time-divisionally distribute the input signal transmitted by the same signal output end to any one of the plurality of data signal lines DATA, so as to reduce the number of signal output ends under the premise of realizing normal output of the data signal, and reduce the difficulty of layout of the signal output ends in the display panel.
[0188] Optionally, the display area AA further comprises a first display area AA1 and a second display area AA2. The second display area AA2 is located on both sides of the first display area AA1 along the second direction Y, as shown in FIG. 2, but is not limited thereto. In this arrangement, along the orientation shown in FIG. 2, the second display area AA2 is located between the first display area AA1 and the non-display areas NAA on the left and right sides, and along the second direction Y, the first display area AA1 is closer to the center of the display panel, and the second display area AA2 is closer to the edge of the display panel.

At least part of the data connection trace FIAA is located in the display area AA, and at least part of the data connection trace FIAA is located in the first display area AA1. In this way, the demultiplexing unit DEMUX connected to the data signal line DATA and the data connection trace FIAA can be more concentrated below the first display area AA1, so that the connection line when the data signal line DATA and the data connection trace FIAA are connected to the demultiplexing switch K occupies less space in the first direction, which is beneficial to reducing the occupied space of the non-display area, and is beneficial to improving the display area ratio of the display panel and improving the screen-to-body ratio of the display panel.
[0189] For example, FIG. 3 illustrates an example in which the demultiplexing unit DEMUX includes two demultiplexing switches K1 and K2. Correspondingly, the display panel includes two switch control lines SW1 and SW2, the control end of the demultiplexing switch K1 is electrically connected to the switch control line SW1, the control end of the demultiplexing switch K2 is electrically connected to the switch control line SW2, and the switch control lines SW1 and SW2 transmit the enable signals of the demultiplexing switches in time division. When the enable signal is transmitted in the switch control line SW1, the demultiplexing switch K1 is turned on, and the demultiplexing switch K1 is used to transmit the data signal input by the input end to the data signal line DATA directly or through the data connection trace FIAA to the data signal line connected thereto. Similarly, when the enable signal is transmitted in the switch control line SW2, the demultiplexing switch K2 is turned on, and the demultiplexing switch K2 is used to transmit the data signal input by the input end to the data signal line DATA directly or through the data connection trace FIAA to the data signal line connected thereto.
[0190] Referring to FIGS. 4-41, the signal lines can further include a power signal line PVDD, the first sub-wiring section FIAA11 and the second sub-wiring section FIAA12 connected to the same demultiplexing unit DEMUX are located on two sides of the power signal line PVDD, and the overlapping part of the first sub-wiring section FIAA11 and the second sub-wiring section FIAA12 in the second direction is symmetric about the first virtual axis X1, that is, the first sub-wiring section FIAA11 and the second sub-wiring section FIAA12 connected to the same demultiplexing unit DEMUX are an axisymmetric structure, and the axis of symmetry can be the first virtual axis X1 passing through the center of the power signal line PVDD, and the first virtual axis X1 is also the boundary line of the adjacent two pixel circuit classes. The first sub-wiring section FIAA11 and the second sub-wiring section FIAA12 connected to the same demultiplexing unit DEMUX are an axisymmetric structure, and the boundary line of the adjacent two pixel circuit classes is used as the axis of symmetry, which not only makes the two first-wire sections connected to the same demultiplexing unit DEMUX regular, but also helps to make the color deviation of the display image have better symmetry, so that the four-direction color deviation can be changed, that is, the consistency and accuracy of the color can be improved when viewing the display image from any direction, and the display image can be viewed from a wider angle range without feeling obvious color change, thereby enhancing the user experience.
[0191] In summary, the display panel provided by the embodiments of the present application has the following advantages.

In this way, the data signal line in the second display area can be avoided from being directly electrically connected to the output end of the demultiplexing switch, and the area of the non-display area can be avoided from being increased due to the direct electrical connection between the data signal line in the second display area and the output end of the demultiplexing switch, thereby improving the screen-to-body ratio of the display panel. Optionally, the first-wire section FIAA1 includes the first sub-wiring section FIAA11 and the second sub-wiring section FIAA12, and the overlapping part of the first sub-wiring section FIAA11 and the second sub-wiring section FIAA12 in the second direction is symmetric about the first virtual axis X1. In this way, the two first-wire sections connected to the same demultiplexing unit DEMUX are regular, and the color deviation of the display image has better symmetry, so that the four-direction color deviation can be changed.
