[0037] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] It will be understood that the terms "first," "second," etc., used herein may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a pixel circuit may be referred to as a second pixel circuit, and similarly, a second pixel circuit may be referred to as a pixel circuit. Both a pixel circuit and a second pixel circuit are pixel circuits, but they are not the same pixel circuit.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the description of this application, the meaning of "several" is at least one, such as one, two, etc., unless otherwise clearly and specifically defined.

[0040] The display modules involved in the embodiments of the present application can be applied to display devices with narrow bezels. The display devices can be smartphones, tablets, gaming devices, augmented reality (AR) devices, laptops, desktop computing devices, wearable devices, etc. For ease of understanding, the following example uses a mobile phone as the display device.

[0041] Figure 1 is a schematic diagram of the structure of a display module according to one embodiment. Referring to Figure 1 , the display module comprises a display area 10, a fan-out area 20, and a binding area 30 arranged sequentially along a first direction. The display area comprises a first display area 101 and a second display area 102 arranged sequentially along a second direction. The fan-out area and the second display area 102 are adjacent to each other, and the first and second directions intersect with each other. The first and second directions are perpendicular to the thickness of the display module. The display area is the AA area (Active Area) capable of displaying images. The first display area 101 can be understood as the display area located at the edge of the AA area, and the second display area 102 can be understood as the display area located in the middle of the AA area. The fan-out area is used to set the fan-out wiring. The binding area 30 is used to set the display driver chip.

[0042] As shown in Figure 2, the display module includes: multiple data lines 110 and multiple first connection lines 120 arranged in the display area, and multiple fan-out lines (not shown in the figure) arranged in the fan-out area. The fan-out lines are used to transmit the data signals output by the binding area 30 to the data lines 110.

[0043] A plurality of data lines 110 are provided in the display area 10, and the plurality of data lines 110 extend along the first direction and are arranged along the second direction; a plurality of first connecting lines 120 (differentiated by lines of different thicknesses in the figure, wherein the data lines 110 are thinner lines and the first connecting lines 120 are thicker lines) are provided in the display area 10, and the first ends of the plurality of first connecting lines 120 are respectively connected to the data lines 110 located in the first display area 101, and the second ends of the plurality of first connecting lines 120 are located in the second display area 102; between two adjacent data lines 110 located in the first display area 101, the first ends of the plurality of first connecting lines 120 are respectively connected to the data lines 110 located in the first display area 101, and the second ends of the plurality of first connecting lines 120 are located in the second display area 102; The distance between the first connection line 120 corresponding to the data line 110 away from the second display area 102 and the virtual intersection is greater than the distance between the first connection line 120 corresponding to the data line 110 close to the second display area 102 and the virtual intersection; the virtual intersection is the intersection (point A in the figure) of the first extension line (such as line Y1 in the figure) and the second extension line (line Y2 in the figure), the first extension line is the extension line of the side edge of the first display area 101 away from the second display area 102, and the second extension line is the extension line of the side edge of the second display area 102 close to the fan-out area 20.

[0044] Multiple fan-out traces are provided in the fan-out area 20, one end of some of the fan-out traces are respectively connected to the data lines 110 located in the second display area 102, and another end of the fan-out traces are respectively connected to the second ends of the multiple first connection traces 120, and the other ends of the multiple fan-out traces are respectively connected to the multiple pins arranged along the second direction in the binding area 30, each pin is used to transmit a data signal to the corresponding connected data line 110, and each pin is used to transmit a data signal to the corresponding connected data line 110, and the arrangement order of each pin in the multiple pins is the same as the arrangement order of each data line 110 connected thereto in the multiple data lines 110.

[0045] Among them, the multiple data lines 110 include several data lines 110 arranged in the first display area 101 and several data lines 110 arranged in the second display area 102. The several data lines 110 arranged in the first display area 101 can be connected to the several fan-out lines of the fan-out area 20 through the multiple first connecting lines 120, and the several data lines 110 arranged in the second display area 102 can be directly connected to the several fan-out lines of the fan-out area 20.

[0046] First, the second ends of the plurality of first connecting traces 120 connected to the plurality of fan-out traces are located in the second display area 102. Thus, the plurality of first connecting traces 120 can be used to transfer the plurality of fan-out traces corresponding to the plurality of data lines 110 of the first display area 101 to the second display area 102, away from the edge area of ​​the display module. This allows the fan-out area 20 to be concentrated in the central area below the second display area 102, reducing the fan-out area 20's winding space and, in turn, reducing the width of the display module's bottom bezel. It is understood that the proportion of the plurality of data lines 110 located in the first display area 101 to the total number of data lines 110 in the display module can be set based on the outer contour shape of the display module or the width requirements of the bottom bezel, and this is not limited in this embodiment. Furthermore, it is understood that the size of the second display area 102 along the second direction is generally greater than the size of the first display area 101 along the second direction. Therefore, the second display area 102 has more space to accommodate the plurality of first connecting traces 120.

[0047] On the second aspect, the lower frame edge area of ​​the first display area 101 close to the virtual intersection is close to the fan-out area 20 in the first direction and away from the second display area 102 in the second direction. The lower frame edge area is usually a rounded area in the edge display area. In this area, the data line 110 away from the second display area 102 is usually shorter than the data line 110 close to the second display area 102. Therefore, by setting the distance between the two adjacent data lines 110 in the first display area 101, the distance between the first connection line 120 corresponding to the data line 110 away from the second display area 102 and the virtual intersection is greater than the distance between the first connection line 120 corresponding to the data line 110 close to the second display area 102 and the virtual intersection. The connection lines can be arranged in other places outside the lower frame edge area, reducing the occupancy of the lower frame edge area and further narrowing the size of the lower frame.

[0048] On the third aspect, in possible related technologies, the first connecting line 120 corresponding to the data line 110 in the first display area 101 far away from the second display area 102 is usually set to be close to the virtual intersection, and the first connecting line 120 corresponding to the data line 110 in the first display area 101 close to the second display area 102 is far away from the virtual intersection, so that the size of the connecting line in the first direction is larger, resulting in a larger overall area occupied by the connecting line, so that the coupling strength between the connecting line and the data line 110 is greater when transmitting signals. In this embodiment, the distance between the first connection line 120 corresponding to the data line 110 far away from the second display area 102 and the virtual intersection is set to be greater than the distance between the first connection line 120 corresponding to the data line 110 close to the second display area 102 and the virtual intersection, so that the size of the outermost first connection line 120 in the first direction is greater than the size of the other inner first connection lines 120 close to the edge area of ​​the lower frame in the first direction. As a result, the size of the inner connection lines is smaller and the overall wiring area is smaller, which can further reduce the coupling between the first connection line 120 and the data line 110 when transmitting signals, thereby reducing the parasitic capacitance generated between the two, and effectively reducing the delay and attenuation of the data signal during transmission.

[0049] The order of arrangement of the data signal pins of the binding area 30 among the plurality of pins is the same as the order of arrangement of the corresponding data lines 110 among the plurality of data lines 110, and each pin is used to transmit a data signal to the corresponding data line. In a possible related art, if the arrangement order of the plurality of fan-out traces in the fan-out area 20 is not converted, since the second end of the first connecting trace 120 is located in the second display area 102, the arrangement order of the second end of the first connecting trace 120 and the data line 110 in the second display area 102 will be disrupted, resulting in a mismatch between the order of the plurality of data lines 110 originally arranged in the second direction. In this embodiment, the first connection line 120 and the data line 110 of the second display area 102, whose arrangement order is disrupted, can be transferred to the multiple pins of the binding area 30 in the order in which the data lines 110 were originally arranged along the second direction through the fan-out routing of the fan-out area 20, so that the multiple pins of the binding area 30 still maintain the same arrangement order as the data line 110, without changing the arrangement order of the pins, saving the production cost of the display panel, and meeting the narrow frame requirement without affecting the function of the binding area 30.

[0050] The display module provided in this embodiment includes multiple data lines 110 and multiple first connection lines 120 arranged in the display area, and multiple fan-out lines arranged in the fan-out area 20. The fan-out lines are used to transmit data signals output from the binding area 30 to the data lines 110. Among them, through multiple first connecting lines 120, several fan-out lines corresponding to several data lines 110 of the first display area 101 can be transferred to the second display area 102, away from the edge area of ​​the display module, so that the winding of the fan-out area 20 is concentrated in the middle area of ​​the lower side of the second display area 102, reducing the winding space of the fan-out area 20, and thus reducing the width of the lower frame of the display module; by setting the first connecting lines 120 corresponding to the data lines 110 far away from the second display area 102 in the first display area 101 to be far away from the lower virtual intersection, and the first connecting lines 120 corresponding to the data lines 110 close to the second display area 102 in the first display area 101 to be close to the virtual intersection, the connecting lines can be arranged in other places outside the edge area of ​​the lower frame, reducing the occupancy of the edge area of ​​the lower frame, further narrowing the size of the lower frame, and making the overall wiring area smaller, so as to further reduce the coupling between the first connecting lines 120 and the data lines 110 when transmitting signals, thereby reducing the parasitic capacitance generated between the two, and effectively reducing the delay and attenuation of the data signal during transmission. In addition, through the fan-out routing of the fan-out area 20, the first connecting routing 120 and the data line 110 of the second display area 102 whose arrangement order is disrupted can be transferred to the multiple pins of the binding area 30 in the order in which the data lines 110 were originally arranged along the second direction, so that the multiple pins of the binding area 30 still maintain the same arrangement order as the data line 110, and there is no need to change the arrangement order of the pins, which saves the production cost of the display panel and meets the narrow bezel requirement without affecting the function of the binding area 30.

[0051] In some embodiments, as shown in Figure 3, among two adjacent first connection lines, the extension size of the first connection line away from the virtual intersection in the first direction is larger than the extension size of the first connection line close to the virtual intersection in the first direction; the extension size of the first connection line away from the virtual intersection in the second direction is larger than the extension size of the first connection line close to the virtual intersection.

[0052] Therefore, on the one hand, the first connecting line away from the virtual intersection forms the outer routing of the first connecting line close to the virtual intersection, and the first connecting line close to the virtual intersection forms the inner routing of the first connecting line away from the virtual intersection, so that the connecting lines can be arranged in other places other than the edge area of ​​the lower frame close to the virtual intersection, reducing the occupation of the edge area of ​​the lower frame and further narrowing the size of the lower frame; on the other hand, the overall wiring area is smaller, and at the same time, the coupling between the first connecting line 120 and the data line 110 when transmitting signals is further reduced, thereby reducing the parasitic capacitance generated between the two, and effectively reducing the delay and attenuation of the data signal during the transmission process; in addition, through the above-mentioned setting method, there is no intersection between different first connecting lines 120, so there will be no parasitic capacitance or signal interference between different first connecting lines 120, thereby improving the stability and reliability of the signal transmitted by the first connecting line 120.

[0053] In some embodiments, as shown in FIG3 , a portion of the first connecting trace 120 extending along the first direction has its projection in the thickness direction of the display module located in the gap between two adjacent data lines 110. The gap between two adjacent data lines 110 can be understood as an idle position that does not require additional space. On the one hand, this facilitates the arrangement of the first connecting trace 120 in the first direction and improves the uniformity of the arrangement between the first connecting trace 120 and the two adjacent data lines 110 in the second direction. On the other hand, this idle position also facilitates the connection of another portion of the first connecting trace 120 extending in other directions.

[0054] It can be understood that in some optional embodiments, a first connecting line 120 can be set in the gap between two adjacent data lines 110. In some optional embodiments, multiple first connecting lines 120 can be set in the gap between two adjacent data lines 110. The specific adjustment and setting are based on the display type, display area, etc. of the display module, and this embodiment does not make further limitations.

[0055] Furthermore, the display module includes a plurality of pixel circuits 130, which are arranged in a plurality of columns. The first direction is parallel to the column direction of the pixel circuits 130. Each column includes a plurality of pixel circuits 130, and each pixel circuit 130 is configured to connect to a light-emitting device 140 to drive the connected light-emitting device 140 to emit light. Each data line 110 transmits a data signal to the pixel circuits 130 in the column direction. Optionally, as shown in FIG4 (data lines 110 are not shown), the two adjacent data lines 110 may be an R / G data line 110 and a B data line 110, respectively. The R / G data line 110 is configured to transmit a data signal to the pixel circuits 130 corresponding to the R / G column, causing the pixel circuits 130 to drive the connected R / G light-emitting devices 140 to emit light; and the B data line 110 is configured to transmit a data signal to the pixel circuits 130 corresponding to the B column, causing the pixel circuits 130 to drive the connected B light-emitting devices 140 to emit light. The adjacent R light emitting device 140 , G light emitting device 140 and two B light emitting devices 140 may form a pixel unit (eg, four light emitting devices 140 surrounded by a dotted box in the figure).

[0056] It will be understood that in the embodiment of FIG4 , the color of the light-emitting device 140 corresponding to each pixel circuit 130 is only for illustrative purposes and is not intended to limit the scope of protection of this application. The multiple pixel circuits 130 in the display module are arranged in multiple columns, and the first direction is parallel to the column direction of the pixel circuits 130. It will be understood that in this embodiment, the number of pixel circuits 130 in each column may be the same or different, and may be specifically set according to the shape of the actual module, and this embodiment does not further limit this. For example, if the display module is in the shape of a special-shaped screen such as a water drop screen or a notch screen, then in each column of the special-shaped area, the number of pixel circuits 130 may be less than the number of first pixels in other columns. For another example, if an under-screen camera needs to be set below the display module during installation, then in each column of the area corresponding to the under-screen camera, the number of pixel circuits 130 may be less than the number of pixel circuits 130 in other columns.

[0057] It is understood that the pixel circuit 130 can select a corresponding circuit type according to actual needs. For example, the pixel circuit 130 with a 7T1C structure as shown in Figure 5 can be selected, and other types of pixel circuits 130 such as 3T1C, 6T1C, and 6T2C can also be selected. Taking the pixel circuit 130 with a 7T1C structure as an example, the pixel circuit 130 may include a driving transistor T1, an anode reset unit 511, a gate reset unit 512, a data writing unit 513, a threshold compensation unit 514, and a light emitting control unit 515 as shown in Figure 5. Those skilled in the art will already know the relevant functions of each unit by referring to the pixel circuit 130 with a 7T1C structure shown in Figure 5, so this embodiment will not further explain them.

[0058] In some embodiments, a portion of the routing and the data lines 110 are in the same routing layer of the display module; the other portion of the first connecting routing 120 except for a portion of the routing and the data lines 110 are in a different routing layer of the display module; wherein the other portion of the routing is connected to a portion of the routing and the corresponding data lines 110 through vias.

[0059] Among them, a portion of the first connecting lines 120 located in the gaps between adjacent data lines 110 are in the same routing layer as the data lines 110, which can effectively utilize the space in the routing layer where the data lines 110 are located while avoiding contact between the first connecting lines 120 and the data lines 110, and is also conducive to simplifying the preparation process.

[0060] Among them, except for a part of the routing, another part of the routing of the first connecting line 120 is in a different routing layer of the display module from each data line 110, and the other part of the routing is connected to a part of the routing line and the data line 110 through a via, thereby avoiding the overlap of the other part of the routing with the data line 110 and reducing the coupling between the other part of the routing and the data line 110, thereby reducing the parasitic capacitance generated between the two and reducing the delay and attenuation of the data signal during the transmission process.

[0061] Furthermore, the display module also includes a substrate. As shown in FIG6 , the substrate may include a polyimide (PI) substrate 612 and a first buffer layer 613, a first gate insulating layer 614, an interlayer insulating layer 615, and a plurality of planarization layers 616, which are alternately arranged in sequence. In the embodiment shown in FIG12 , the substrate includes two polyimide (PI) substrates 612 and two first buffer layers 613, which are alternately arranged in sequence. It is understood that the substrate may also include a greater number of polyimide (PI) substrates 612 and first buffer layers 613. The aforementioned portion of the routing and each data line 110 may be a metal layer in the planarization layer 613 (corresponding to the SD3 layer in the figure), and the aforementioned other portion of the routing may be a metal layer in another planarization layer 613 (corresponding to the SD2 layer in the figure). Thus, the aforementioned portion of the routing, each data line 110, and the other portion of the routing are in different routing layers. The data line 110 and a portion of the routing use the SD3 layer, which is far away from the underlying film layer, and can significantly reduce the load on the data line 110. At the same time, the planarization layer 613 between the SD2 layer and the underlying film layer, and between the SD2 layer and the upper SD3 is an organic layer. The parasitic capacitance between the SD2 layer and the SD3 layer can be significantly reduced, thereby reducing the load on the data line 110 and reducing the impact on the display effect.

[0062] Among them, the first gate insulation layer 614, the interlayer insulation layer 615 and the multiple planarization layers 616 on the substrate can be used to form the pixel circuit 130. Specifically, the pixel circuit 13060 includes multiple transistors, and the structure of the transistor includes a first gate 601, a first source 602, a first drain 603, a source contact structure 604 and a corresponding drain contact structure 605, and the anode 607 layer in the light-emitting device 140 is electrically connected to the first source 602 through the source contact structure 604.

[0063] Furthermore, when a portion of the first connecting trace 120 extending along the first direction is in the same trace layer as the data line 110, the width of the gap between the two adjacent data lines 110 is greater than the width threshold. The width threshold can be understood as a width that can ensure that the first connecting trace 120 will not affect the performance of the display module: on the one hand, it includes not affecting the optical performance, that is, the first connecting trace 120 will not cause abnormal light emission problems in the display module. On the other hand, it also includes not affecting the electrical performance, that is, the electrical signal of the first connecting trace 120 will not interfere with the electrical signals in other traces. Therefore, in this embodiment, by setting a gap of appropriate width between adjacent data lines 110, the impact of the first connecting trace 120 on the display performance can be effectively reduced, thereby improving the display quality of the display module.

[0064] In some embodiments, the projection of a portion of the first connecting line 120 extending along the first direction in the thickness direction of the display module may also at least partially overlap with the adjacent data line 110, so as to narrow the gap between the adjacent data lines 110, thereby reducing the overall occupied area of ​​the entire line to achieve extreme space compression.

[0065] In some embodiments, as shown in FIG. 7 , the first connecting trace 120 includes a first trace portion 121 and a second trace portion 122 .

[0066] The first routing portion 121 is at least partially disposed in the first display area 101. One end of the first routing portion 121 is connected to a corresponding data line 110 disposed in the first display area 101. The extension direction of the first routing portion 121 is parallel to the second direction. The second routing portion 122 is disposed in the second display area 102. One end of the second routing portion 122 is connected to the first routing portion 121, and the other end of the second routing portion 122 is connected to the corresponding fan-out routing. The second routing portion 122 extends along the first direction.

[0067] By aligning the extension directions of the first and second routing portions 121, 122 with the second and first directions on the display module, the design and process difficulties can be significantly reduced, and the manufacturing yield rate can be improved. It is understood that when the first and second routing portions 121, 122 are located on different routing layers, the first routing portion 121 can be connected to the second routing portion 122 via a via. It is understood that, in conjunction with the above embodiment, for two adjacent first connecting routing portions 120, the extension dimension of the first routing portion 121 away from the virtual intersection is greater than the extension dimension of the first routing portion 121 near the virtual intersection, and the extension dimension of the second routing portion 122 away from the virtual intersection is greater than the extension dimension of the second routing portion 122 near the virtual intersection. This can reduce the occupancy of the lower frame edge area, further narrowing the size of the lower frame. It can also reduce the overall wiring area, further reducing the coupling between the first connecting routing portion 120 and the data line 110 during signal transmission, thereby reducing the parasitic capacitance generated between the two, and effectively reducing the delay and attenuation of the data signal during transmission.

[0068] In some embodiments, as shown in Figure 8, the display module also includes: multiple second connecting lines 150 and multiple third connecting lines 160 (for ease of illustration in the figure, the second connecting lines 150 and the third connecting lines 160 are both indicated by dotted lines, which is only for illustration, and other parts are indicated by solid lines in the drawings).

[0069] Multiple second connecting lines 150 are arranged in the display area, and the extension directions of the multiple second connecting lines 150 are respectively the same as the extension directions of the first wiring portions 121, and the multiple second connecting lines 150 are separated from each first wiring portion 121 (the partition area is not shown in the figure, but the second connecting lines 150 are actually separated from the first wiring portions 121); multiple third connecting lines 160 are arranged in the display area, and the extension directions of the multiple third connecting lines 160 are respectively the same as the extension directions of the second wiring portions 122, and the multiple third connecting lines 160 are separated from each second wiring portion 122 (the partition area is not shown in the figure, but the third connecting lines 160 are actually separated from the second wiring portions 122).

[0070] The second connecting trace 150 extends in the same direction as the first trace portion 121, and the second connecting trace 150 can be understood as a trace extending in the second direction and arranged in the first direction. The third connecting trace 160 extends in the same direction as the second trace portion 122, and the third connecting trace 160 can be understood as a trace extending in the first direction and arranged in the second direction. It should be noted that the second connecting trace 150 and the third connecting trace 160 do not need to transmit signals, so there is no need to set up any data lines 110 connected to the second connecting trace 150 and the third connecting trace 160. The positions of the second connecting trace 150 and the third connecting trace 160 can be understood as idle positions, without taking up additional space. Moreover, the uniformity of the signal line arrangement can be effectively improved, thereby suppressing the problem of screen mura.

[0071] By comparing the embodiments of Figures 3 and 8, the first connecting trace 120 is set in part of the first display area 101 and the second display area 102 of the embodiment of Figure 3, while the first connecting trace 120 is not set in other parts. The first connecting trace 120 is a metal trace. It can be understood that the metal trace has a certain reflective effect, while the gap does not have any reflective effect. Therefore, the reflective effect at different positions of the display module is not exactly the same, which will accordingly cause the display module's screen-off mura problem. Obviously, the second connecting trace 150 and the third connecting trace 160 are set in the gap of the embodiment of Figure 8, so that the reflective effect at the gap can be similar to the reflective effect of the part where the first connecting trace 120 is set, thereby suppressing the display module's screen-off mura problem. That is, in terms of screen-off mura, the performance of the display module of the embodiment of Figure 8 is better than that of the display module of the embodiment of Figure 3.

[0072] In addition, the consistent structure of the display area in the display module is also beneficial to the stability of the process, ensuring the consistency of the electrical properties of the thin film transistors and the uniformity of the display. Moreover, from the perspective of circuit design, the configuration of this embodiment can reduce the design difficulty of the display module, and can be integrated to form a wiring extending along the second direction, forming a partition at the position between the first wiring portion 121 and the second connecting wiring 150, thereby forming the first wiring portion 121 and the second connecting wiring 150; similarly, a wiring extending along the first direction can be integrated to form a partition at the position between the second wiring portion 122 and the third connecting wiring 160, thereby forming the second wiring portion 122 and the third connecting wiring 160; during the formation process, it can also reduce the influence of various optical effects on the difference in size structure during the exposure preparation process, thereby improving the preparation yield of the display module.

[0073] In some embodiments, as shown in FIG. 9 (the display area is not shown in the figure), the fan-out area includes a first fan-out area 201 and a second fan-out area 202 , and the second fan-out area 202 is located between the first fan-out area 201 and the binding area 30 .

[0074] The plurality of fan-out lines include a plurality of first fan-out lines 210 , a plurality of second fan-out lines 220 , and a plurality of third fan-out lines 230 .

[0075] Multiple first fan-out traces 210 are provided in the first fan-out region 201 and are connected to the data lines 110 in the second display region 102 and the other ends of the multiple first connection traces 120. Thus, the multiple first fan-out traces 210 can direct all data lines 110 in the first display region 101 to the first fan-out region 201 via the multiple first connection traces 120, and can also directly direct all data lines 110 in the second display region 102 to the first fan-out region 201.

[0076] Multiple second fan-out traces 220 and multiple third fan-out traces 230 are provided in the second fan-out area 202. One ends of the multiple second fan-out traces 220 are respectively connected to the multiple first fan-out traces 210. The other ends of some of the second fan-out traces 220 are respectively connected to some pins of the binding area 30. The other ends of some of the second fan-out traces 220 are respectively connected to another part of the pins of the binding area 30 through the multiple third fan-out traces 230. Thus, the multiple second fan-out lines 220 can transfer all the data lines 110 in the display area to the second fan-out area 202 through the first fan-out lines 210. At the same time, the arrangement order of the multiple second fan-out lines 220 can be converted through the third fan-out lines 230, so that the order of the multiple third fan-out lines 230 and the multiple second fan-out lines 220 finally connected to the multiple pins in the binding area 30 is consistent with the order of the original multiple data lines 110 arranged in sequence along the second direction, so that the multiple pins in the binding area 30 still maintain the same arrangement order as the data lines 110, and there is no need to change the arrangement order of the pins.

[0077] Thus, this embodiment, through the use of multiple first fan-out traces 210, multiple second fan-out traces 220, and multiple third fan-out traces 230, can achieve the transfer of the disrupted order of the first connection traces 120 and the data lines 110 of the second display area 102 to the multiple pins of the binding area 30 in the original order of the data lines 110 along the second direction. This ensures that the multiple pins of the binding area 30 remain in the same order as the data lines 110, eliminating the need to change the pin order. This reduces the manufacturing cost of the display panel and achieves the narrow bezel requirement without affecting the functionality of the binding area 30. Furthermore, the third fan-out trace 230 is connected to the display area via the second fan-out trace 220. As a result, the dimension of the third fan-out trace 230 in the first direction is smaller than that of the second fan-out trace 220. This significantly reduces the area occupied by the routing conversion region in the second fan-out area 202, reduces wiring complexity, and increases the space in the second fan-out area 202 to accommodate other traces.

[0078] In some embodiments, the third fan-out wiring 230 and the second fan-out wiring 220 are respectively located in different wiring layers of the display module, and the wiring layers are perpendicular to a direction perpendicular to both the first direction and the second direction.

[0079] The third fan-out trace 230 and the second fan-out trace 220 are located on different routing layers. This prevents the third fan-out trace 230 from overlapping and short-circuiting the second fan-out trace 220. It also reduces coupling between the third fan-out trace 230 and the second fan-out trace 230, thereby reducing parasitic capacitance generated between the two and minimizing data signal delay and attenuation during transmission. Furthermore, this allows the second fan-out area 202 to have more space to accommodate other traces and to accommodate vias for switching between traces. Furthermore, multiple third fan-out traces 230 can be electrically connected to the second fan-out traces via vias located on their routing layer and / or vias located on the routing layer where the second fan-out trace 220 resides.

[0080] Furthermore, as shown in FIG10 (the display area is not shown in the figure), any two adjacent second fan-out traces 220 are alternately arranged on different trace layers of the display module, and any two adjacent third fan-out traces 230 are alternately arranged on different trace layers of the display module. By alternately arranging any two adjacent second fan-out traces 220 on different trace layers, and any two adjacent third fan-out traces 230 on different trace layers, the number of fan-out traces arranged on the same trace layer can be further reduced, so that the setting positions of the fan-out traces in the same trace layer can be more flexibly selected and adjusted to better match the target wiring requirements.

[0081] Furthermore, as shown in FIG11 (which can be combined with reference to FIG6 ), the display module also includes: a substrate and a gate insulation layer, an interlayer insulation layer and a plurality of planarization layers stacked in sequence on the substrate; wherein any two adjacent second fan-out traces 220 are alternately arranged in the gate insulation layer and the interlayer insulation layer, and any two adjacent third fan-out traces 230 are alternately arranged in two adjacent planarization layers.

[0082] The gate insulating layer, the interlayer insulating layer and the plurality of planarizing layers may be referred to the above embodiments and will not be described in detail here.

[0083] By alternately disposing the third fan-out traces 230 in the trace layers of adjacent planarization layers (the trace layers in the adjacent planarization layers correspond to the SD2 and SD3 layers in Figures 6 and 11 ), and the second fan-out traces 220 in the trace layers of the interlayer insulation layer (the trace layers in the adjacent planarization layers correspond to the GE1 and GE2 layers in Figures 6 and 11 ), the planarization layers and interlayer insulation layers can be organic insulation layers, typically 1.5 μm to 2 μm, which is beneficial for loading parasitic capacitance and reducing crosstalk between the second fan-out traces 220 and the third fan-out traces 230. The SD2 and SD3 layers can be made of, but are not limited to, Ti / Al / Ti.

[0084] Furthermore, in the case of alternating routing, the orthographic projections of any two adjacent second fan-out routings 220 on the same routing layer of the display module can be arranged in parallel and at equal intervals as required, so that the wiring of the orthographic projections of the second fan-out routings 220 of different routing layers on the same routing layer is more uniform and more regular; and / or, the orthographic projections of any two adjacent third fan-out routings 230 on the same routing layer of the display module can be arranged in parallel and at equal intervals as required, so that the wiring of the orthographic projections of the third fan-out routings 230 of different routing layers on the same routing layer is more uniform and more regular.

[0085] Furthermore, when the routing is alternately arranged, the orthographic projections of any two adjacent second fan-out routings 220 on the same routing layer of the display module at least partially overlap, which can make the orthographic projections of the second fan-out routings 220 of different routing layers on the same routing layer concentrated in one area, thereby reducing the space occupied by the second fan-out routings 220 in the overall spatial layout, which is beneficial to narrowing the fan-out area or increasing the space to accommodate other routings; and / or the orthographic projections of any two adjacent third fan-out routings 230 on the same routing layer of the display module at least partially overlap, which can make the orthographic projections of the third fan-out routings 230 of different routing layers on the same routing layer concentrated in one area, thereby reducing the space occupied by the third fan-out routing 230 in the overall spatial layout, which is beneficial to narrowing the fan-out area or increasing the space to accommodate other routings.

[0086] In some embodiments, as shown in FIG. 12 (the display area is not shown in the figure), the display module further includes: a shielding layer 40 .

[0087] The shielding layer 40 is provided between the routing layer where the second fan-out routing line 220 is located and the routing layer where the third fan-out routing line 230 is located, and is connected to a preset voltage signal.

[0088] Among them, the preset voltage signal can be understood as a fixed voltage signal. Since the shielding layer 40 is arranged between the routing layer where the second fan-out routing 220 is located and the routing layer where the third fan-out routing 230 is located, and is connected to a fixed voltage signal, the corresponding capacitance and voltage difference are constant, so the corresponding signal interference is constant, which can remove signal interference and retain valid signal data, thereby preventing signal crosstalk between the second fan-out routing 220 and the third fan-out routing 230, and reducing the delay and attenuation of the data signal during transmission.

[0089] Furthermore, the preset voltage signal can be a power supply (VDD) signal. Thus, the shielding layer 40 can be a power routing layer. On the one hand, the power routing layer has the basic function of power signal transmission. On the other hand, based on the aforementioned setting position and the transmission of the fixed voltage signal, the power routing layer also has a signal shielding function. Thus, the power routing layer can be reused without the need to introduce other shielding layers to achieve the corresponding signal shielding function. It is understood that in other embodiments, the preset voltage signal can also be other types of signals, such as a ground (VSS) signal, and the shielding layer 40 can be a ground routing layer, etc., which will not be introduced one by one here.

[0090] Furthermore, as shown in FIG12 , the orthographic projection of shielding layer 40 on second fan-out region 202 at least partially covers second fan-out trace 220 and third fan-out trace 230. Thus, shielding layer 40 can at least partially isolate crosstalk between second fan-out trace 220 and third fan-out trace 230. Furthermore, the orthographic projection of shielding layer 40 on second fan-out region 202 can completely cover second fan-out trace 220 and third fan-out trace 230, thereby completely isolating crosstalk between second fan-out trace 220 and third fan-out trace 230 and effectively reducing delay and attenuation of data signals during transmission.

[0091] Further, referring to the above embodiment, when the third fan-out routing 230 is alternately arranged in the routing layer in the adjacent planarization layer (the routing layer in the adjacent planarization layer corresponds to the layer where SD2 and SD3 are located in Figures 6, 11, and 13), and the second fan-out routing 220 is alternately arranged in the routing layer in the interlayer insulating layer (the routing layer in the adjacent planarization layer corresponds to the layer where GE1 and GE2 are located in Figure 6), the shielding layer 40 can be arranged in the planarization layer between the routing layer where the third fan-out routing 230 is located and the routing layer where the second fan-out routing 220 is located (such as the layer where SD1 is located in Figures 6 and 13).

[0092] In some embodiments, the display module further includes a bending region 203; multiple first fan-out traces 210 are connected to corresponding second fan-out traces 220 via multiple traces in the bending region 203. Thus, multiple first fan-out traces 210 can be transferred to second fan-out traces 220 via the traces in the bending region 203. Furthermore, the provision of the bending region 203 facilitates bending the second fan-out region 202 toward the back side of the display module, thereby increasing the screen-to-body ratio.

[0093] It can be understood that in possible embodiments, each of the routing lines in the above embodiments can extend in a straight line, or can at least partially extend in a non-linear shape, for example, can extend in a broken line, a serpentine shape, or a wavy shape, etc. This embodiment does not further limit this.

[0094] In some embodiments, the fan-out area includes a first fan-out area 201 and a second fan-out area 202 , wherein the second fan-out area 202 is located between the first fan-out area 201 and the binding area 30 ; the plurality of fan-out traces may include: a plurality of first fan-out traces 210 , a plurality of fourth fan-out traces, and a plurality of fifth fan-out traces.

[0095] Multiple first fan-out traces 210 are provided in the first fan-out region 201 and are respectively connected to the data lines 110 in the second display region 102 and the second ends of the multiple first connection traces 120. The description of the multiple first fan-out traces 210 can be found in the above embodiment and will not be repeated here.

[0096] Multiple fourth fan-out traces are provided in the second fan-out area 202, one ends of the multiple fourth fan-out traces are respectively connected to a portion of the first fan-out traces 210, and the other ends of the multiple fourth fan-out traces are respectively connected to a portion of the pins in the binding area 30; a portion of the first fan-out traces 210 are respectively connected to the first connecting traces 120; multiple fifth fan-out traces are provided in the second fan-out area 202, one ends of the multiple fifth fan-out traces are respectively connected to a portion of the first fan-out traces 210, and the other ends of the multiple fifth fan-out traces are respectively connected to another portion of the pins in the binding area 30; another portion of the first fan-out traces 210 are respectively connected to the data lines 110 of the second display area 102.

[0097] Therefore, in combination with multiple fourth fan-out lines and multiple fifth fan-out lines, all data lines 110 in the display area can be transferred to the second fan-out area 202 through the first fan-out line 210, and replaced sequentially in the second fan-out area 202, so that the order of the multiple fourth fan-out lines and multiple fifth fan-out lines finally connected to the multiple pins in the binding area 30 is consistent with the order of the original multiple data lines 110 arranged in sequence along the second direction, so that the multiple pins in the binding area 30 still maintain the same arrangement order as the data lines 110, and there is no need to change the arrangement order of the pins.

[0098] Therefore, this embodiment uses multiple first fan-out lines 210, multiple fourth fan-out lines, and multiple fifth fan-out lines to achieve the first connecting lines 120 and the data lines 110 of the second display area 102 whose arrangement order is disrupted, and transfers them to the multiple pins of the binding area 30 in the order in which the data lines 110 are originally arranged along the second direction, so that the multiple pins of the binding area 30 still maintain the same arrangement order as the data lines 110, without changing the arrangement order of the pins, saving the production cost of the display panel, and meeting the narrow frame requirement without affecting the function of the binding area 30.

[0099] It is understood that the plurality of fourth fan-out routes and the plurality of fifth fan-out routes may also be located in different routing layers, and adjacent fourth fan-out routes may also be alternately located in different routing layers, and adjacent fifth fan-out routes may also be alternately located in different routing layers. The routing of the plurality of fourth fan-out routes and the plurality of fifth fan-out routes can refer to the routing of the plurality of second fan-out routes 220 and the plurality of third fan-out routes 230 in the above embodiment, and will not be further described in this embodiment.

[0100] In some embodiments, the edge of the fan-out region away from the display region is smaller than the edge of the fan-out region closer to the display region. Thus, first fan-out traces 210 in first fan-out region 201 are at least partially tilted toward the center region. A greater tilt results in a smaller dimension of first fan-out traces 210 in the first direction, facilitating narrowing of first fan-out region 201. Second fan-out traces 220 in second fan-out region 202 are at least partially tilted toward the center region. A greater tilt results in a smaller dimension of second fan-out traces 220 in the first direction, facilitating narrowing of second fan-out region 202.

[0101] In some embodiments, as shown in Figure 14, the display module is provided with two first display areas 101, and the two first display areas 101 are respectively provided on opposite sides of the second display area 102 in the second direction; wherein, the overall outer contour of the second display area 102 and the two first display areas 101 is a rounded rectangular shape, the first display area 101 is the rounded corner area in the rounded rectangle, and the second display area 102 is the rectangular area in the rounded rectangle.

[0102] Through the plurality of first connection lines 120, the plurality of first fan-out lines 210 correspondingly connected to the plurality of data lines 110 in the first display area 101, which is a rounded corner area, can be transferred to the second display area 102, away from the rounded corner area of ​​the display area, so that the winding of the first fan-out area 201 is concentrated in the middle area below the second display area 102, which is a rectangular area, thereby reducing the winding space of the first fan-out area 201 and further reducing the width of the bottom frame of the display module.

[0103] It is understandable that if the configuration of the first connecting trace 120 in this embodiment is not adopted, the fan-out traces in the rounded corner area must be connected to the bend area 203 using a nearly arc-shaped trace. However, the manufacturing difficulty of the arc-shaped trace is relatively high, which will affect the production yield and even the display quality of the display module. Therefore, the configuration of the first connecting trace in this embodiment allows the use of a straight-line trace for the rounded corner area, thereby reducing the manufacturing difficulty of the fan-out trace.

[0104] Based on the same inventive concept as the above-mentioned embodiment, the embodiment of the present application also provides a display module of another embodiment, wherein the display module is provided with a display area, a fan-out area and a binding area arranged in sequence along a first direction, the display area includes a first display area and a second display area arranged in sequence along a second direction, the fan-out area is adjacent to the second display area, the first direction and the second direction intersect with each other, and the display module includes: multiple data lines, multiple first connection lines, and multiple fan-out lines.
