[0050] Here, there is no limitation on the specific type of the driver chip IC. Illustratively, the driver chip can be a display driver chip, or the driver chip can be a TDDI chip.

[0051] Here, there is no limitation on the specific type of the fan-out wiring 2. Exemplarily, the fan-out wiring 2 may include display fan-out wiring (also called display driving line or source driving line), or the fan-out wiring 2 may include touch fan-out wiring, or the fan-out wiring 2 may include display fan-out wiring and touch fan-out wiring at the same time.

[0052] When the display panel is a touch and display integrated display panel (TDDI display panel), the fan-out wiring includes display fan-out wiring and touch fan-out wiring at the same time.

For example, two touch electrode wirings TX and one data signal line Data may be laid out alternately in order, or may be laid out alternately in another manner. In this case, the touch fan-out wiring located in the fan-out area F and electrically connected to the touch electrode wiring TX and the display fan-out wiring electrically connected to the data signal line Data may be laid out alternately. Therefore, a part of the display fan-out wiring may be arranged to extend from the fan-out area F to the area where the first side edge 101 is located and electrically connected to the output terminal 4, and another part of the display fan-out wiring may be arranged to be electrically connected to the output terminal 4 via the wing-shaped wiring 3, and a part of the touch fan-out wiring may be arranged to extend from the fan-out area F to the area where the first side edge 101 is located and electrically connected to the output terminal 4, and another part of the touch fan-out wiring may be arranged to be electrically connected to the output terminal 4 via the wing-shaped wiring 3.

[0059] Of course, as shown in FIG. 15, all of the touch fan-out wirings 22 may be arranged to extend from the fan-out region F to the region where the first side edge 101 is located and be electrically connected to the output terminal 4, and a portion of the display fan-out wiring 21 may be arranged to be electrically connected to the output terminal 4 via the wing-shaped wiring 3 (the first wing-shaped wiring 31 and the second wing-shaped wiring 32).

[0060] The display panel may be any one of an LCD (Liquid Crystal Display) display panel, an OLED (Organic Light Emitting Diode) display panel, a Mini LED display panel, or a Micro LED display panel.

[0061] The dimensions of the display panel are not limited, and may be applied to a large or extra-large (e.g., 86-inch) UHD (Ultra High Definition) display device or HD (High Definition) display device, or may be applied to a small (e.g., 23.6-inch) UHD display device or HD display device.

[0062] The display panel may be a non-TDDI (Touch and Display Driver Integration) technology display panel, or may be a TDDI technology display panel.

[0063] For example, the display panel of TDDI technology can be divided into an ADS (Advanced Super Dimension Switch) type liquid crystal touch display or a HADS type liquid crystal touch display, and the specific type of the display panel is not limited thereto.

[0064] In practical applications, for a non-TDDI technology display panel, the driver chip IC is a display driver chip, the driver signal line 1 is a display driver line (Source line), and the display driver line transmits the display driver signal output from the display driver chip to the data signal line (Data line) in the display panel to control the display of each pixel unit in the display area.

[0065] On the other hand, for a display panel using TDDI technology, the driving chip IC is a TDDI chip, the driving signal line 1 includes a display driving line and a touch driving line, the display driving line transmits a display driving signal output from the TDDI chip to a data signal line (Data line) in the display panel to control the display of each pixel unit in the display area, and the touch driving line transmits a touch driving signal output from the TDDI chip to a touch electrode wiring (TX line) in the display panel to control a touch sensor to realize a touch function.

[0066] Since the fan-out area of ​​the display panel of the TDDI technology is provided with not only the display driving lines but also the touch driving lines, the design space of the fan-out area of ​​the display panel of the TDDI technology is more limited, and it is more difficult to realize high frequency charging.

[0067] However, in the display panel of the embodiment of the present application, multiple wing-shaped wires 3 are installed in the bind area B, and the wing-shaped wires 3 are wound (including winding at the upper, left and right sides and lower positions of the driving chip) so that some of the fan-out wires 2 are electrically connected to the output terminals 4 of the driving chip via the wing-shaped wires 3, thereby utilizing the area in the bind area B where no driving chip is installed, shortening the length of the fan-out wires 2 electrically connected to the wing-shaped wires 3, and significantly reducing the space occupied by the fan-out wires 2 in the fan-out area B. In practical applications, the line width of the fan-out wires 2 and the distance between two adjacent fan-out wires 2 can be further increased to significantly reduce the resistance of the fan-out wires 2 themselves, thereby realizing high-frequency charging of each pixel unit in the display area AA, increasing the charging rate of the display panel, shortening the charging time, and reducing the power consumption of the display panel.

[0068] In addition, in actual applications, as shown in Figures 1 and 3, a part of the fan-out wiring 2 is electrically connected to the output terminal 4 of the driving chip by winding the wing-shaped wiring 3, so that the area in the bind area B where the driving chip is not installed is utilized, and the length of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 is shortened, and further the dimension d2 of the fan-out area F in the direction along the display area AA toward the fan-out area F is reduced, so that compared with the dimension d1 of the fan-out area F in the related art in the direction along the display area AA toward the fan-out area F, d2 can be 0.1 mm-0.2 mm smaller than d1, which is advantageous for manufacturing a narrow-frame display panel.

[0069] In an exemplary embodiment, as shown in FIG. 18, the wing wiring 3 passes through the area where the first side edge 101 is located.

[0070] In practical application, when winding through the wing-shaped wiring 3, a certain design space is released between the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 and the fan-out wiring 2 not electrically connected to the wing-shaped wiring 3, and the wing-shaped wiring 3 extends from the bind area B to the fan-out area F and is wound in the area where the first side edge 101 is located, thus the fan-out wiring 2 of that part is electrically connected to the output terminal 4 through the wing-shaped wiring 3. Because the space in the area where the first side edge 101 is located is limited, in some cases a small number of wing-shaped wirings 3 can be installed to pass through the area where the first side edge 101 is located and electrically connected to the output terminal 4, thereby reducing the design space occupied by the fan-out wiring 2 in the fan-out area B to a certain extent.

[0071] However, Figure 18 is drawn as an example in which a portion of the wing-shaped wiring 3 passes through the area where the first side edge 101 is located, and a portion of the wing-shaped wiring 3 passes through the area where the third side edge 103 is located.

[0072] In an exemplary embodiment, as shown in FIG. 4, the wing trace 3 passes through the area where the second side edge 102 of the driver chip IC is located.

[0073] In practical applications, a circuit board is further provided between the second edge 102 of the driving chip IC and the edge of the display panel, and the wing-shaped wiring 3 can pass through the area between the second edge 102 and the circuit board, and further pass through the area where the second edge 102 is located to be electrically connected to the output terminal 4 of the driving chip.

[0074] In an exemplary embodiment, a portion of the wing-shaped wiring 3 passes through the area where the second side edge 102 of the driver chip IC is located, and another portion of the wing-shaped wiring 3 passes through the area where at least one of the two third side edges 103 of the driver chip IC is located.

[0075] In an exemplary embodiment, as shown in FIG. 3, the wing wiring 3 passes through the area where at least one of the two third side edges 103 of the driver chip IC is located.

[0076] In practical applications, the design space on both sides (103) of the driving chip IC and below the driving chip IC in the binding area B is relatively sufficient, so that the wing-shaped wiring 3 can be installed to be wound in the areas on both sides (103) and below (102) of the driving chip IC.

[0077] For example, when the wing-shaped wiring 3 passes through the area where at least one of the two third side edges 103 of the driver chip IC is located, the number of the wing-shaped wiring 3 (i.e., the number of the fan-out wiring 2 to be wound) is related to the minimum distance between the area where the output terminal 4 of the driver chip is located and the area where the input terminal 5 of the driver chip is located, the line width of the wing-shaped wiring 3, and the gap between two adjacent wing-shaped wirings 3. For example, the sum (Pitch) of the line width of the wing-shaped wiring 3 and the gap between two adjacent wing-shaped wirings 3 is 4.0 μm, and the minimum distance between the area where the output terminal 4 of the driver chip is located and the area where the input terminal 5 of the driver chip is located is 400 μm, so that 100 wing-shaped wirings 3 can be installed, that is, 100 fan-out wirings 2 can be wound. In practical applications, the number of windings of each fan-out wiring 2 can be determined according to the situation, and is not limited here.

[0078] In an exemplary embodiment, as shown in FIG. 18, a portion of the wing wiring 3 passes through the area where the first side edge 101 is located, and another portion of the wing wiring 3 passes through the area where at least one of the two third side edges 103 is located.

[0079] In practical application, a part of the fan-out wiring 2 is electrically connected to the output terminal 4 of the driver chip after being wound in the bind area B through the wing-shaped wiring 3, and in the fan-out area F, there is an available space F1 between the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 and the fan-out wiring 2 not electrically connected to the wing-shaped wiring 3, so that the wing-shaped wiring 3 is extended from the bind area B to the area marked with F1 in FIG. 18, and further passes through the area where the first side edge 101 of the driver chip is located, and is electrically connected to the output terminal 4. In addition, another part of the wing-shaped wiring 3 is set to pass through the area where at least one of the two third side edges 103 is located, so that the number of the fan-out wiring 2 electrically connected to the output terminal 4 through the wing-shaped wiring 3 can be greatly increased, and the design space of the fan-out area F can be released. In practical applications, by further increasing the line width of the fan-out wiring 2 and the distance between two adjacent fan-out wirings 2, the resistance of the fan-out wiring 2 itself can be significantly reduced, thereby enabling high-frequency charging of each pixel unit in the display area AA, increasing the charging rate of the display panel, shortening the charging time, and reducing the power consumption of the display panel.

[0080] In some embodiments of the present application, as shown in FIG. 21 , the display panel further includes a plurality of receiving terminals 41, the receiving terminals 41 are arranged to be bound to the output terminals 4 of the driving chip, the orthogonal projection of the receiving terminals 41 on the substrate of the display panel overlaps with the orthogonal projection of the output terminals 4 on the substrate, some of the receiving terminals 41 are electrically connected to the fan-out wiring 2 passing through the area where the first side edge 101 is located, and another part of the receiving terminals 41 are electrically connected to the wing-shaped wiring 3; For a receiving terminal 41 electrically connected to the wing-shaped wiring 3, an orthogonal projection of the wing-shaped wiring 3 on the substrate and an orthogonal projection of at least one receiving terminal 4 on the substrate overlap with each other.

[0081] In an exemplary embodiment, the orthogonal projection of the receiving terminal 41 on the substrate of the display panel overlaps with the orthogonal projection of the output terminal 4 on the substrate, meaning that there is an overlapping area between the orthogonal projection of the outer contour of the receiving terminal 41 on the substrate of the display panel and the orthogonal projection of the outer contour of the output terminal 4 on the substrate, or that the orthogonal projection of the outer contour of the receiving terminal 41 on the substrate of the display panel completely overlaps with the orthogonal projection of the outer contour of the output terminal 4 on the substrate.

[0082] In the drawings relating to the embodiments of the present application, the orthogonal projection of the outer periphery of the receiving terminal 41 on the substrate of the display panel and the orthogonal projection of the outer periphery of the output terminal 4 on the substrate are shown to completely overlap with each other, so in the related drawings showing the output terminal 4 equipped with a driving chip, only the structure of the output terminal 4 is shown, and the structure of the receiving terminal 41 on the display panel is not embodied, and will be described here.

[0083] In an exemplary embodiment, the receiving terminals 41 and the output terminals 4 of the driving chip are connected in a one-to-one correspondence, and either the wing-shaped wiring 3 or the fan-out wiring 2 is first electrically connected to the receiving terminals 41, and then the receiving terminals 41 are electrically connected to the output terminals 4 of the driving chip by binding.

[0084] In an exemplary embodiment, for a receiving terminal 41 electrically connected to the wing-shaped wiring 3, the orthogonal projection of the wing-shaped wiring 3 on the substrate and the orthogonal projection of at least one receiving terminal 4 on the substrate overlap, as shown in FIG. 21 , taking a first set of receiving terminals S1 as an example, the first set of receiving terminals S1 includes five receiving terminals 41, and here, for the first receiving terminal 41, there is an overlap in the direction perpendicular to the substrate for each of the wing-shaped wirings 3 electrically connected to the five receiving terminals 41 in the first set of receiving terminals S1, and for the second receiving terminal 41, there is an overlap in the direction perpendicular to the substrate for each of the other four wing-shaped wirings 3 electrically connected to the first receiving terminal 41 among the first set of receiving terminals S1. This means that all of the lines 3 have overlaps in the direction perpendicular to the substrate, and for the third receiving terminal 41, the other three wing-shaped wires 3 of the first set of receiving terminals S1, excluding the wing-shaped wires 3 electrically connected to the first and second receiving terminals 41, all have overlaps in the direction perpendicular to the substrate, for the fourth receiving terminal 41, the other two wing-shaped wires 3 of the first set of receiving terminals S1, excluding the wing-shaped wires 3 electrically connected to the first, second and third receiving terminals 41, all have overlaps in the direction perpendicular to the substrate, and for the fifth receiving terminal 41, only the wing-shaped wire 3 electrically connected to the fifth receiving terminal 41 has overlaps in the direction perpendicular to the substrate.

[0085] However, FIG. 21 relating to the embodiment of the present application is drawn only as an example in which the first set of receiving terminals S1 includes five receiving terminals, the second set of receiving terminals S2 includes five receiving terminals, and the left area of ​​the binding area B includes ten wing-shaped wirings, and in actual applications, the specific number is not limited and can be determined based on design needs.

[0086] Furthermore, however, Figure 21 relating to the embodiment of the present application is drawn only as an example when the multiple receiving terminals 41 are laid out in two rows, and in actual applications, the multiple receiving terminals 41 may be further laid out in three rows, or the multiple receiving terminals 41 may be laid out in four rows, or may be laid out in another manner, and specifically, may be determined based on the layout manner of the output terminals 4, and is not limited here.

[0087] In the related art shown in Figure 20, the design is such that the orthogonal projection of the fan-out wiring 2 on the substrate and the orthogonal projection of the receiving terminal 41 on the substrate do not overlap with each other. In contrast, in the embodiment of the present application, as shown in Figure 21, the wing-shaped wiring 3 is wound and the receiving terminal 41 electrically connected to the wing-shaped wiring 3 is arranged so that the orthogonal projection of the wing-shaped wiring 3 on the substrate and the orthogonal projection of at least one receiving terminal 4 on the substrate overlap with each other. This, on the one hand, saves design space in the fan-out region F of the display panel, and on the other hand, saves space between multiple receiving terminals 41, and allows for more flexible design of the layout position of the receiving terminal 41, which allows for more flexible setting of the layout position of the output terminal 4 in the driving chip, or allows for more flexible selection of the type of matching driving chip.

[0088] 21 according to an embodiment of the present application, the design dimensions of one of the fan-out area F and the bind area B are shown in FIG 27. As is clear, the width of the fan-out area F (the distance from the edge of the display area AA to the first side edge of the driving chip IC) is 1.01mm, the distance from the first side edge to the second side edge of the driving chip is 0.77mm, the width of the flexible circuit board (FPC) is 0.35mm, the distance from the driving chip to the flexible circuit board is 0.3mm, and the distance from the flexible circuit board (FPC) to the edge of the display panel (the edge of the array substrate) is 0.07mm, that is, the width of the bind area is 1.49mm, and the width of the lower frame of the display panel is 1.01mm+1.49mm=2.5mm. On the other hand, the design dimensions of the display panel in the related art shown in Fig. 20 are shown in Fig. 26, and in comparison, it can be seen that the width of the fan-out area F (the distance from the edge of the display area AA to the first side edge of the driving chip IC) of the display panel shown in Fig. 21 according to the embodiment of the present application is 0.1 mm smaller than the width of the fan-out area F of the display panel in the related art. Here, the unit of the marked numbers in Fig. 26 and Fig. 27 is millimeters (mm).

[0089] In some embodiments of the present application, as shown in FIG. 21, the receiving terminals 41 electrically connected to the wing-shaped wirings 3 are divided into a first set S1 laid out along the first side edge 101 and a second set S2 laid out along the second side edge 102, and each wing-shaped wiring 3 electrically connected to the receiving terminals S1 of the first set is provided in the same layer, and the wing-shaped wirings 3 electrically connected to the receiving terminals S2 of the second set include a first wing-shaped wiring 31 and a second wing-shaped wiring 32, and the first wing-shaped wiring 31 and the second wing-shaped wiring 32 are located in different layers; Here, the wing-shaped wiring 3 electrically connected to the first set of receiving terminals S1 and each second wing-shaped wiring 32 in the wing-shaped wiring 3 electrically connected to the second set of receiving terminals S2 are provided in the same layer.

[0090] In an exemplary embodiment, the wing-shaped wiring 3 electrically connected to the first set of receiving terminals S1 and each second wing-shaped wiring 32 in the wing-shaped wiring 3 electrically connected to the second set of receiving terminals S2 are made of the same material, for example, the material is the same as the material of the source / drain metal layer (SD) in the display area AA, or the material is the same as the material of the gate (Gate) in the display area AA.

[0091] In an exemplary embodiment, if the material of the wing-shaped wiring 3 is the same as the material of the source / drain metal layer (SD) in the display area AA, the wing-shaped wiring 3 can be fabricated in the same layer as the source / drain metal layer (SD) in the display area AA, and if the material of the wing-shaped wiring 3 is the same as the material of the gate (Gate) in the display area AA, the wing-shaped wiring 3 can be fabricated in the same layer as the gate (Gate) in the display area AA.

[0092] In some embodiments of the present application, as shown in FIG. 25, the receiving terminal 41 electrically connected to the wing-shaped wiring 3 is a gate layer located on a substrate 401, the gate layer including two conductive pads 404 disposed opposite each other independently; a dielectric layer 405 covering the gate layer and exposing a portion of each of the conductive pads 404; a source / drain metal layer 406 covering the dielectric layer 405 and in direct contact with some areas of the exposed conductive pads 404; and an electrode layer 407 arranged to cover the source / drain metal layer 406 and to be in direct contact with the output terminal 4 of the driver chip.

[0093] The gate layer and the gate layer in the display area AA are made of the same material, are provided in the same layer, and are fabricated in a primary patterning process.

[0094] The electrode layer 407 and the pixel electrodes in the display area AA are made of the same material, are provided in the same layer, and are fabricated in a primary patterning process.

[0095] The electrode layer 407 covering the source / drain metal layer 406 means that the orthogonal projection of the electrode layer 407 on the substrate covers the orthogonal projection of the source / drain metal layer 406 on the substrate, and the orthogonal projection area of ​​the electrode layer 407 on the substrate is larger than the orthogonal projection area of ​​the source / drain metal layer 406 on the substrate. This can play a role in protecting the source / drain metal layer 406.

[0096] As shown in FIG. 25, the receiving terminal 41 further includes a buffer layer 402 located on the substrate 401 and a gate insulating layer 403 located on the buffer layer 402, but of course, the gate insulating layer 403 may be located on the side of the gate layer away from the substrate 401, and the specific details can be determined based on the design of the actual product and are not limited here.

[0097] FIG. 24 shows a plan view of the receiving terminal 41 according to the embodiment of the present invention, and FIG. 25 is a cross-sectional view taken along the line B1B2 of FIG.

[0098] In the related art as shown in Fig. 22 and Fig. 23, the conductive pad 404 of the receiving terminal 41 is made into an integrated block structure and occupies the central region of the receiving terminal 41, whereas in the embodiment of the present application, referring to Fig. 24 and Fig. 25, two conductive pads 404 are provided independently and opposite to each other in the regions of both ends of the receiving terminal 41, so that, on the one hand, one of the two conductive pads 404 can be used as a spare conductive pad for repairing and replacing when an abnormality occurs in one conductive pad 404, and, on the other hand, since the two conductive pads 404 are provided opposite to each other in the regions of both ends of the receiving terminal 41, the region between the two conductive pads 404 of the receiving terminal 41 is reserved for designing other structures, and the design space can be increased. Here, Fig. 23 is a cross-sectional view taken along the A1A2 direction in Fig. 22.

[0099] In some embodiments of the present application, as shown in Figures 21 and 24, the wing-shaped wiring 3 electrically connected to the first set of receiving terminals S1 and each second wing-shaped wiring 32 in the wing-shaped wiring 3 electrically connected to the second set of receiving terminals S2 are both located in the gate layer and both pass between two conductive pads 404 of the receiving terminal 41.

[0100] In the embodiment of the present application, two conductive pads 404 are arranged opposite to each other in the region at both ends of the receiving terminal 41, so that the region between the two conductive pads 404 of the receiving terminal 41 is reserved. The wing-shaped wiring 3 is located in the gate layer, and the wing-shaped wiring is arranged to pass through the region between the two conductive pads 404 of each receiving terminal 41. Compared with the wiring in the related art that passes through the region between the receiving terminals 41, the design method in the embodiment of the present application can ensure normal and stable transmission of electrical signals, and can greatly save the design space of the binding region and fan-out region of the display panel, which, on the one hand, can realize high frequency charging by appropriately increasing the line width of the wiring, and on the other hand, is advantageous to the production of narrow-bezel display products.

[0101] In some embodiments of the present application, as shown in FIG. 21 , for one receiving terminal 41 of the first set of receiving terminals S1, one wing-shaped wiring 3 is electrically connected to its conductive pad 404, and the orthogonal projections of other wing-shaped wirings electrically connected to the first set of receiving terminals S1 on the substrate and the orthogonal projections of the conductive pads 404 on the substrate do not overlap with each other. For one receiving terminal 41 of the second set of receiving terminals S2, one second wing-shaped wiring 32 is electrically connected to its conductive pad 404, and the orthogonal projection on the substrate of the other second wing-shaped wiring 32 electrically connected to the second set of receiving terminals S2 and the orthogonal projection on the substrate of the conductive pad 404 do not overlap with each other.

[0102] In the embodiment of the present application, since the wing-shaped wiring that overlaps with the receiving terminal 41 in a direction perpendicular to the substrate is located on the gate layer, the conductive pad 404 of the receiving terminal 41 is also located on the gate layer, and in order to ensure that there is no disruption in signal transmission between the receiving terminal 41 and each wing-shaped wiring 3, for each receiving terminal 41 connected to the wing-shaped wiring 3, there is an overlap in the direction perpendicular to the substrate only between one receiving terminal 41 and the wing-shaped wiring 3 electrically connected to it, and there is no overlap in the direction perpendicular to the substrate between the receiving terminal 41 and the other wing-shaped wirings 3.

[0103] In some embodiments of the present application, as shown in FIG. 40, the display panel further includes a plurality of auxiliary receiving terminals 42, the auxiliary receiving terminals 42 have the same structure as the receiving terminal 41; The spare receiving terminal 42 provided in the same row as the receiving terminal S1 of the first set is a first spare receiving terminal, and the spare receiving terminal 42 provided in the same row as the receiving terminal S2 of the second set is a second spare receiving terminal, Here, at least a portion of the wing-shaped wiring 3 electrically connected to the first set of receiving terminals passes through the area between the two conductive pads 404 in the first auxiliary terminal, and at least a portion of the wing-shaped wiring 3 electrically connected to the second set of receiving terminals passes through the area between the two conductive pads 404 in the second auxiliary terminal.

[0104] In an exemplary embodiment, the spare receiving terminal 42 is not electrically connected to the wing wiring 3, as shown in FIG.

[0105] Here, there is no specific limit to the number of the spare receiving terminals (dummy receiving terminals) 42 in the display panel. Illustratively, the number of the spare receiving terminals 42 is five, where the number of the first spare receiving terminals is two and the number of the second spare receiving terminals is three.

[0106] In an exemplary embodiment, the auxiliary receiving terminals 42 are located at both ends of the multiple receiving terminals 41, or as shown in FIG. 40, the auxiliary receiving terminals 42 are located on one side of the multiple receiving terminals 41 (wherein a first auxiliary receiving terminal is located to the left of a first set of receiving terminals 41 and a second auxiliary receiving terminal is located to the left of a second set of receiving terminals 41), or the auxiliary receiving terminals 42 and the receiving terminals 41 are spaced apart.

[0107] In an exemplary embodiment, as shown in Fig. 40, no wing-shaped wiring 3 is installed in the area between two conductive pads 404 in some of the receiving terminals 41, and of course, at least one wing-shaped wiring 3 may pass through the area between two conductive pads 404 in each receiving terminal 41. The specifics can be determined based on the actual situation.

[0108] In some embodiments of the present application, as shown in FIG. 15 , the fan-out wiring 2 includes display fan-out wiring 21 and touch fan-out wiring 22; Each touch fan-out wiring 22 extends from the fan-out region F to the region where the first side edge 101 is located and is electrically connected to the output terminal 4, and a portion of the display fan-out wiring 21 is electrically connected to the output terminal via the wing-shaped wiring 3.

[0109] However, in actual applications, since the number of touch fan-out wires 22 is less than the number of display fan-out wires 21, the display fan-out wires 21 can be installed so as to be electrically connected to the output terminals 4 by winding the wing-shaped wires 3, thereby facilitating the layout of each fan-out wire 2 in the fan-out region F.

[0110] Of course, for current mainstream display products, the number of touch fan-out wiring 22 is less than the number of display fan-out wiring 21, so the display fan-out wiring 21 is installed to be electrically connected to the output terminal 4 by the winding method of the wing-shaped wiring 3; for individual display products, according to design needs, the touch fan-out wiring 22 may also be installed to be electrically connected to the output terminal 4 by the winding method of the wing-shaped wiring 3, and here we will take the current actual demand as an example to explain.

[0111] FIG. 15 according to the embodiment of the present application illustrates an example in which the wing-shaped wiring 3 passes only through the region where the second side edge 102 is located.

[0112] In an exemplary embodiment, in the structure shown in FIG. 18, when the wing-shaped wiring 3 passes through the area where the first side edge 101 is located, a certain design space is released between the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 and the fan-out wiring 2 not electrically connected to the wing-shaped wiring 3 for the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 in this portion, and the wing-shaped wiring 3 extends from the bind area B to the fan-out area F and is wound in the area where the first side edge 101 is located, thus the fan-out wiring 2 in that portion is electrically connected to the output terminal 4 through the wing-shaped wiring 3. Since the space in the area where the first side edge 101 is located is limited, the wing-shaped wiring 3 electrically connected to the display fan-out wiring 21 can be installed to pass through the area where the first side edge 101 is located and electrically connected to the output terminal 4.

[0113] In an exemplary embodiment, in a structure as shown in FIG. 4 , when the wing-shaped wire 3 passes through the area where the second edge 102 of the driving chip IC is located, the fan-out wires 2 electrically connected to the wing-shaped wire 3 in this portion may be installed such that all the fan-out wires 2 in this portion are display fan-out wires 21, so that the display fan-out wires 21 pass through the area where the second edge 102 of the driving chip IC is located and are further electrically connected to the output terminals 4, and the display fan-out wires 21 and all the touch fan-out wires 22 in the other portions extend from the fan-out area F to the bind area B, and are electrically connected to the output terminals 4 after passing through the area where the first edge is located.

[0114] In an exemplary embodiment, as shown in FIG. 28, the fan-out wiring 2 includes a display fan-out wiring 21 and a touch fan-out wiring 22, each of which extends from the fan-out area F to the area where the first side edge 101 is located, and is electrically connected to a receiving terminal 41, which is electrically connected to an output terminal 4 (the structure of the output terminal 4 of the driving chip is not shown in FIG. 28), and a portion of the display fan-out wiring 21 is electrically connected to the receiving terminal 41 via a wing-shaped wiring 3, and each of the wing-shaped wiring 3 passes through the area where both sides (third side edge 103) of the driving chip are located.

[0124] In an exemplary embodiment, as shown in FIG. 31 , each touch fan-out wiring 22 and a portion of the display fan-out wiring 21 extend from the fan-out region F to the region where the first side edge 101 is located, and are electrically connected to the receiving terminal 41, and a portion of the display fan-out wiring 21 is installed so as to be electrically connected to the receiving terminal 41 via the wing-shaped wiring 3.

[0125] Here, the display fan-out wiring 21 electrically connected to the receiving terminal 41 via the wing-shaped wiring 3 is divided into two parts, and the display fan-out wiring 21 of the first part passes through the area where the lower side (second side edge 102) of the driving chip is located via the wing-shaped wiring 3, passes through the area where the input terminal 5 is located, and is electrically connected to the output terminal 4 (actually, it is electrically connected to the receiving terminal 41 first, and the receiving terminal 41 is electrically connected to the output terminal 4). The wing-shaped wiring 3 connected to the display fan-out wiring 21 of the second part passes through the area where both sides (third side edge 103) of the driving chip are located, passes through the area between the two conductive pads 404 of the receiving terminal 41, and is further electrically connected to one conductive pad 404 of the corresponding receiving terminal 41, and here, the wing-shaped wiring 3 connected to the display fan-out wiring 21 of the second part is located in the gate layer and is provided in the same layer as the conductive pad 404.

[0126] In an exemplary embodiment, as shown in FIG. 32 , each touch fan-out wiring 22 and a portion of the display fan-out wiring 21 extend from the fan-out region F to the region where the first side edge 101 is located and are electrically connected to the output terminal 4, and a portion of the display fan-out wiring 21 is arranged to be electrically connected to the output terminal 4 via the wing-shaped wiring 3. Here, the display fan-out wiring 21 electrically connected to the output terminal 4 via the wing-shaped wiring 3 is divided into two parts, the display fan-out wiring 21 of the first part passes through the area where the upper side (first side edge 101) of the driving chip is located and is electrically connected to the output terminal 4 via the wing-shaped wiring 3, and each wing-shaped wiring 3 electrically connected to the display fan-out wiring 21 of the second part includes a first wing-shaped wiring 31 and a second wing-shaped wiring 32, the first wing-shaped wiring 31 and the second wing-shaped wiring 32 are located in different layers, and for each first wing-shaped wiring 31, there is an overlap with the second wing-shaped wiring 32 electrically connected to it in a direction perpendicular to the substrate, and the extension direction of the overlapping area is parallel to the extension direction of the first wing-shaped wiring 31.

[0127] In an exemplary embodiment, as shown in FIG. 37 or FIG. 38, the wing wiring 3 includes display wing wiring and touch wing wiring, and the fan-out wiring 2 includes display fan-out wiring 21 and touch fan-out wiring 22; A portion of the display fan-out wiring 21 is electrically connected to the output terminal 4 via the display wing wiring, and a portion of the touch fan-out wiring 22 is electrically connected to the output terminal 4 via the touch wing wiring.

[0128] However, in Figures 37 and 38 relating to the embodiments of the present application, no distinction is made between the marks indicating the wing wires and the touch wing wires, and here the wing wires 3 electrically connected to the display fanout wires 21 are display wing wires, and the wing wires 3 electrically connected to the touch fanout wires 22 are touch wing wires.

[0129] In an exemplary embodiment, as shown in Fig. 37, a part of the touch fan-out wiring 22 and a part of the display fan-out wiring 21 extend from the fan-out region F to the area where the first side edge 101 is located, and are electrically connected to the receiving terminal 41, and the receiving terminal 41 is electrically connected to the output terminal 4 (the structure of the output terminal 4 of the driving chip is not shown in Fig. 37), another part of the display fan-out wiring 21 is electrically connected to the receiving terminal 41 through the display wing-shaped wiring, and another part of the touch fan-out wiring 22 is electrically connected to the receiving terminal 41 through the touch wing-shaped wiring. And the wing-shaped wiring 3 (including the display wing-shaped wiring and the touch wing-shaped wiring) all pass through the area where both sides (the third side edge 103) of the driving chip are located.

[0130] In an exemplary embodiment, as shown in FIG. 38, for a submerged driving chip, the area occupied after its output terminals 4 and input terminals 5 are laid out is triangular, so the design space between the area where the output terminals 4 are located and the area where the input terminals 5 are located is limited, and a part of the touch fan-out wiring 22 and a part of the display fan-out wiring 21 extend from the fan-out area F to the area where the first side edge 101 is located and electrically connected to the output terminals 4, another part of the display fan-out wiring 21 passes through the area where the underside (second side edge 102) of the driving chip is located through the display wing-shaped wiring, passes through the area where the input terminals 5 are located and electrically connected to the output terminals 4, and another part of the touch fan-out wiring 22 passes through the area where the underside (second side edge 102) of the driving chip is located through the touch wing-shaped wiring, passes through the area where the input terminals 5 are located and electrically connected to the output terminals 4.

[0131] In an exemplary embodiment, as shown in FIG. 39, a portion of the touch fan-out wiring 22 and a portion of the display fan-out wiring 21 extend from the fan-out region F to the region where the first side edge 101 is located and are electrically connected to the output terminal 4, another portion of the display fan-out wiring 21 is electrically connected to the output terminal 4 via the display wing-shaped wiring, and another portion of the touch fan-out wiring 22 is electrically connected to the output terminal 4 via the touch wing-shaped wiring.

[0132] Here, the display fan-out wiring 21 electrically connected to the output terminal 4 via the display wing-shaped wiring (the wing-shaped wiring 3 electrically connected to the display fan-out wiring 21) is divided into two parts, the display fan-out wiring 21 of the first part passes through the area where the upper side (first side edge 101) of the driving chip is located and is electrically connected to the output terminal 4 via the display wing-shaped wiring, and each display wing-shaped wiring electrically connected to the display fan-out wiring 21 of the second part includes a first wing-shaped wiring 31 and a second wing-shaped wiring 32, the first wing-shaped wiring 31 and the second wing-shaped wiring 32 are located in different layers, and for each first wing-shaped wiring 31, there is an overlap with the second wing-shaped wiring 32 electrically connected to it in a direction perpendicular to the substrate, and the extension direction of the overlapping area is parallel to the extension direction of the first wing-shaped wiring 31.

[0133] The touch fan-out wiring 22 electrically connected to the output terminal 4 via the touch wing-shaped wiring (the wing-shaped wiring 3 electrically connected to the touch fan-out wiring 22) is also divided into two parts, the touch fan-out wiring 22 of the first part passes through the area where the upper side (first side edge 101) of the driving chip is located and electrically connected to the output terminal 4 via the touch wing-shaped wiring, and each touch wing-shaped wiring electrically connected to the touch fan-out wiring 22 of the second part also includes a first wing-shaped wiring 31 and a second wing-shaped wiring 32, the first wing-shaped wiring 31 and the second wing-shaped wiring 32 are located in different layers, and each first wing-shaped wiring 31 overlaps with the second wing-shaped wiring 32 electrically connected thereto in a direction perpendicular to the substrate, and the extension direction of the overlapping area is parallel to the extension direction of the first wing-shaped wiring 31.

[0134] In an exemplary embodiment, the wing wiring 3 may be located on the same layer, as shown in Figures 4, 6 and 7 .

[0135] If the material of the wing-shaped wiring 3 is the same as the material of the source / drain metal layer (SD) in the display area AA, the wing-shaped wiring 3 can be fabricated in the same layer as the source / drain metal layer (SD) in the display area AA, and if the material of the wing-shaped wiring 3 is the same as the material of the gate (Gate) in the display area AA, the wing-shaped wiring 3 can be fabricated in the same layer as the gate (Gate) in the display area AA.

[0136] For example, as shown in Figures 4, 6 and 7, the layout order of the ends of each wing-shaped wiring 3 connected to the fan-out wiring 2 is reversed to the layout order of the ends of each wing-shaped wiring 3 connected to the output terminals 4, and in this case, the driver chip can adjust the order of the output signals of the output terminals 4 to avoid the problem of signal disturbance caused by the mismatch in the wiring position order. Here, Figure 7 is an enlarged schematic view of a partial area of ​​Figure 6.

[0137] In some embodiments of the present application, as shown in FIG. 18, a part of the wing wiring 3 is provided in the same layer, and another part of the wing wiring 3 includes a first wing wiring 31 and a second wing wiring 32, and the first wing wiring 31 and the second wing wiring 32 are located in different layers; Here, the wing-shaped wiring 3 provided in the same layer includes a first line segment a, a second line segment b, a third line segment c, a fourth line segment d and a fifth line segment e connected in sequence, where the first line segment a and the second line segment b are located in the bind area B, the third line segment c extends from the bind area B to the fan-out area F, the fourth line segment d and the fifth line segment e are located in the fan-out area F, the first line segment a is electrically connected to the fan-out wiring 2, and the fifth line segment e is electrically connected to the output terminal 4.

[0138] In addition, the layout order of the fan-out wirings 2 electrically connected to the first line segment a, the layout order of the first line segment a, the layout order of the fifth line segment e, and the layout order of the output terminals 4 electrically connected to the fifth line segment e are all the same, thereby ensuring electrical connection between each fan-out wiring 2 and the output terminals 4 corresponding to the signals and avoiding problems with signal distortion.

[0139] In practical application, a part of the fan-out wire 2 is electrically connected to the output terminal 4 of the driver chip after being wound in the bind area B through the wing-shaped wire 3, and in the fan-out area F, there is an available space F1 between the fan-out wire 2 electrically connected to the wing-shaped wire 3 and the fan-out wire 2 not electrically connected to the wing-shaped wire 3, so the wing-shaped wire 3 is extended from the bind area B to the area marked with F1 in FIG. 18, and then passes through the area where the first side edge 101 of the driver chip is located, and is electrically connected to the output terminal 4. In this way, more fan-out wires 2 can be installed to be electrically connected to the output terminal 4 in the manner of winding the wing-shaped wire 3, and the design space of the fan-out area F and the bind area B can be reduced.

[0140] In some embodiments of the present application, as shown in Figures 3 and 8, each wing wiring 3 includes a first wing wiring 31 and a second wing wiring 32, and the first wing wiring 31 and the second wing wiring 32 are located in different layers.

[0141] For example, if the material of the first wing-shaped wiring 31 is the same as the material of the source / drain metal layer (SD) in the display area AA, the first wing-shaped wiring 31 can be fabricated in the same layer as the source / drain metal layer (SD) in the display area AA, and if the material of the second wing-shaped wiring 32 is the same as the material of the gate (Gate) in the display area AA, the second wing-shaped wiring 32 can be fabricated in the same layer as the gate (Gate) in the display area AA.

[0142] Alternatively, if the material of the first wing-shaped wiring 31 is the same as the material of the gate in the display area AA, the first wing-shaped wiring 31 can be fabricated in the same layer as the gate in the display area AA, and if the material of the second wing-shaped wiring 32 is the same as the material of the source / drain metal layer (SD) in the display area AA, the second wing-shaped wiring 32 can be fabricated in the same layer as the source / drain metal layer (SD) in the display area AA.

[0143] Here, the first wing-shaped wiring 31 extends along a first direction AF, and the second wing-shaped wiring 32 includes a first line segment 321 extending in a second direction FA, and the first wing-shaped wiring 31 is electrically connected to the fan-out wiring 2 and the first line segment 321 respectively, the first direction AF is a direction in which the display area AA is oriented toward the bind area B, and the second direction FA and the first direction AF are parallel to each other; Here, the orthogonal projection of the first line segment 321 onto the substrate of the display panel and the orthogonal projection of the first wing-shaped wiring 31 electrically connected thereto onto the substrate overlap.

[0144] In an exemplary embodiment, when the line width of the first line segment 321 is less than or equal to the line width of the first wing-shaped wiring 31, the orthogonal projection of the first line segment 321 on the substrate of the display panel is located within the orthogonal projection of the first wing-shaped wiring 31 electrically connected to it on the substrate.

[0145] In an embodiment of the present application, as shown in FIG. 3 , a portion of the fan-out wiring 2 in the fan-out region F is electrically connected to the output terminal 4 of the driving chip through the manner in which the wing-shaped wiring 3 is wound. Therefore, compared with the length d3 of the portion of the fan-out wiring 2 located in the fan-out region F that is not electrically connected to the wing-shaped wiring 3, the length d4 of the portion of the fan-out wiring 2 located in the fan-out region F that is electrically connected to the wing-shaped wiring 3 is significantly shorter, and the resistance of the fan-out wiring 2 not electrically connected to the wing-shaped wiring 3 is much larger than the resistance of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3, which reduces the resistance consistency of the wiring in the display panel and makes signal transmission unstable.

[0146] In the embodiment of the present application, by providing the first line segment 321, the orthogonal projection of the first line segment 321 on the substrate of the display panel overlaps with the orthogonal projection of the first wing-shaped wiring 31 electrically connected thereto on the substrate, and the distance of the wiring from the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 to the output terminal 4 is extended, thereby offsetting to some extent the shortened length of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 and improving the resistance matching between different wirings, thereby improving the stability of signal transmission.

[0147] In some embodiments of the present application, as shown in FIG. 8 , the second wing-shaped wiring 32 further includes a second line segment 322 and a third line segment 323, the second line segment 322 extends along a third direction MN, the first line segment 321, the second line segment 322 and the third line segment 323 are sequentially connected, the third line segment 323 is electrically connected to the output terminal 4, and the third direction MN and the first direction AF intersect; Here, in the third direction MN, the layout order of each of the first wing wirings 31, each of the first line segments 321, and each of the third line segments 323 is the same.

[0148] Specifically, as shown in FIG. 8, the first first wing-shaped wiring 31, the second first wing-shaped wiring 31, the third first wing-shaped wiring 31, the fourth first wing-shaped wiring 31 and the fifth first wing-shaped wiring 31 are laid out sequentially along the third direction MN, the first first line segment 321, the second first line segment 321, the third first line segment 321, the fourth first line segment 321 and the fifth first line segment 321 are laid out sequentially along the third direction MN, and the first third line segment 323, the second third line segment 323, the third third line segment 323, the fourth third line segment 323 and the fifth third line segment 323 are laid out sequentially along the third direction MN.

[0149] In an exemplary embodiment, the angle between the third direction and the first direction may be a right angle, or the angle between the third direction and the first direction may be an obtuse angle. However, the third direction MN shown in the drawings according to the embodiment of the present application is drawn as an example in which the angle between the third direction MN and the first direction AF is a right angle.

[0150] In the embodiment of the present application, by adopting a jumper design, the sequence adjustment between the wing-shaped wiring 3 and the output terminal 4 can be realized, and the fan-out wiring 2 can be electrically connected with its corresponding output terminal 4, and the driver chip does not need to adjust the sequence of the output signals at each output terminal 4.

[0151] However, when the wing-shaped wiring 3 is wound on the second side edge 102 of the driver chip, the jumper design shown in FIG. 8 may be adopted, and FIG. 8 only illustrates the example in which the wing-shaped wiring 3 is wound on the left side (third side edge) of the driver chip.

[0152] In some embodiments of the present application, as shown in FIG. 8 , an angle between the extension line of the first line segment 321 and the extension line of the second line segment 322 is a right angle, an angle between the extension line of the second line segment 322 and the extension line of the third line segment 323 is a right angle, Or, as shown in FIG. 33 , an angle between the extension line of the first line segment 321 and the extension line of the second line segment 322 is an obtuse angle, an angle between the extension line of the second line segment 322 and the extension line of the third line segment 323 is an obtuse angle, and the angles of the two obtuse angles are equal; Alternatively, one of the angle between the extension line of the first line segment and the extension line of the second line segment and the angle between the extension line of the second line segment and the extension line of the third line segment is a right angle, and the other is an obtuse angle.

[0153] In an exemplary embodiment, the orthogonal projection of the first line segment 321 of the second wing-shaped wiring 32 on the substrate partially overlaps with the orthogonal projection of the first wing-shaped wiring connected thereto on the substrate, so that the first line segment 321 can extend the distance of the wiring from the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 to the output terminal 4, thereby offsetting the shortened length of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 to a certain extent, and improving the resistance matching between different wirings, thereby improving the stability of signal transmission. In actual applications, the lengths of the wirings that need to be offset are different, and according to the demands of actual products, the actual length of the second line segment 322 can be controlled by setting the first line segment 321 and the second line segment 322 perpendicularly or setting the angle between the first line segment 321 and the second line segment 322 to an obtuse angle, thereby improving the resistance matching between the wirings. In addition, in order to optimize the layout of wiring in the binding area B of different display products and increase the space utilization rate, it can also be achieved by adjusting the angle of the corner between the first line segment 321 and the second line segment 322.

[0154] In an exemplary embodiment, as shown in FIG. 34, each wing wiring 3 is provided in the same layer, Here, each of the wing-shaped wirings 3 provided in the same layer includes a first line segment a, a second line segment b, a third line segment c, a fourth line segment d, and a fifth line segment e, which are connected in sequence, where the first line segment a and the second line segment b are located in the bind region B, the third line segment c extends from the bind region B to the fan-out region F, the fourth line segment d and the fifth line segment e are located in the fan-out region F, and the first line segment a is electrically connected to the fan-out wiring 2. the fifth line segment e is electrically connected to the output terminal 4, and the angle between the extension line of the second line segment b and the extension line of the third line segment c is a right angle, and the angle between the extension line of the third line segment c and the extension line of the fourth line segment d is a right angle, or the angle between the extension line of the second line segment b and the extension line of the third line segment c is an obtuse angle, and the angle between the extension line of the third line segment c and the extension line of the fourth line segment d is an obtuse angle, and the angles of the two obtuse angles are equal.

[0155] Here, there is no limitation on the specific angle of the obtuse angle, and the specific angle can be determined based on the actual situation.

[0156] In an exemplary embodiment, each of the touch fan-out wires 22 extends from the fan-out region F to the region where the first side edge 101 is located, and is electrically connected to the receiving terminal 41, and the receiving terminal 41 is electrically connected to the output terminal 4, and a part of the display fan-out wires 21 is electrically connected to the receiving terminal 41 through the wing-shaped wire 3, and the wing-shaped wires 3 pass through the region where both sides (the third side edge 103) of the driver chip are located. The display fan-out wires 21 electrically connected to the receiving terminals 41 through the wing-shaped wire 3 can be divided into three parts. Here, the display fan-out wires 21 of the first part are electrically connected to the receiving terminals 41 through the wing-shaped wire 3, and the wing-shaped wire 3 passes through the region where the first side edge 101 is located, and the wing-shaped wire 3 that has passed through the region where the first side edge 101 is located can be divided into three segments, where the angle between the first segment and the second segment is equal to the angle between the second segment and the third segment, as shown in FIG. 35.

[0157] In some embodiments of the present application, as shown in FIG. 8 and FIG. 36, the second wing wiring 32 includes a first line segment 321, a second line segment 322, and a third line segment 323, which are connected in sequence; Here, a first corner G is provided between the first line segment 321 and the second line segment 322, and a second corner (not shown in FIG. 36 ) is provided between the second line segment 322 and the third line segment 323. At least a portion of each corner (including the first corner and the second corner) is a fillet.

[0158] However, FIG. 36 is a partial enlarged view of the area where the first line segment 321 and the second line segment 322 in FIG. 8 are located, and FIG. 36 provides a schematic diagram of the structure of the first corner, and the structure of the second corner is similar to the first corner, and will not be further described.

[0159] In an example embodiment, at least a portion of each corner is a fillet means that a portion of each first corner is a fillet, or each first corner is a fillet, or a portion of each second corner is a fillet, or each second corner is a fillet, or each first corner and each second corner is a fillet.

[0160] Of course, some of the corners may be right angles, and the specifics can be determined based on the actual situation.

[0161] In some embodiments of the present application, as shown in FIG. 36 , at least one island pattern D is provided between two adjacent first corners G, and each island pattern D between two adjacent first corners G is not connected to each other; And / or, at least one island pattern is provided between two adjacent second corners, and each island pattern between two adjacent second corners is not connected to each other.

[0162] In an exemplary embodiment, the island pattern means that the pattern is not connected to other structures around the area where the pattern is located, and the pattern is provided independently. In practical applications, the island pattern may be fabricated in the same layer as the source / drain metal layer using the same material, or in the same layer as the gate layer using the same material, so that the island pattern may be conductive, but is not electrically connected to any other wiring or signal line.

[0163] In an exemplary embodiment, at least one island pattern is provided between two adjacent first corners, and each island pattern between two adjacent first corners is not connected to each other, or at least one island pattern is provided between two adjacent second corners, and each island pattern between two adjacent second corners is not connected to each other, or at least one island pattern is provided between two adjacent first corners, and each island pattern between two adjacent first corners is not connected to each other, and at least one island pattern is provided between two adjacent second corners, and each island pattern between two adjacent second corners is not connected to each other.

[0164] Here, there is no restriction on the number of island patterns D between two adjacent first corners.

[0165] For example, the number of island patterns D between two adjacent first corners is not completely the same, or the number of island patterns D between two adjacent first corners is completely the same. Here, FIG. 36 illustrates an example in which the number of island patterns D between two adjacent first corners is not completely the same. However, the number of island patterns D between two adjacent first corners is not completely the same means that the number of island patterns D between some of the first corners is the same between two adjacent first corners, and the number of island patterns D between other parts of the first corners is different between two adjacent first corners.

[0166] Here, there is no restriction on the number of island patterns D between two adjacent second corners. Illustratively, the number of island patterns D between two adjacent first corners is not completely equal, or the number of island patterns D between two adjacent first corners is completely equal.

[0167] In addition, the number of island patterns D between two adjacent first corners may be the same as the number of island patterns D between two adjacent second corners, or the number of island patterns D between two adjacent first corners may be different from the number of island patterns D between two adjacent second corners.

[0168] Here, there is no limitation on the specific shape and dimensions of the island pattern D between two adjacent first corners. Here, there is no limitation on the specific shape and dimensions of the island pattern D between two adjacent second corners.

[0169] In practical applications, in order to simplify the design, the shape of the island pattern D between two adjacent first corners may be the same as the shape of the island pattern D between two adjacent second corners.

[0170] For example, the projected shape of the island pattern D between two adjacent first corners on the substrate is a shape formed by a circular arc, a polygon, or a combination of a circular arc and a polygon.

[0171] Here, the arc may include a sector, a semicircle, a semi-ellipse, a circle, or an ellipse, and the polygon may include a triangle, a rectangle, a pentagon, or a hexagon.

[0172] For example, the projected shape of the island pattern D between two adjacent second corners on the substrate is the same as the projected shape of the island pattern D between two adjacent first corners on the substrate.

[0173] In an exemplary embodiment, as shown in FIG. 36, the island pattern D between two adjacent first corners and the second wing wiring 32 (including the first line segment 321, the second line segment 322 and the third line segment 323) may be provided in the same layer, and the second wing wiring 32 and the first wing wiring 31 are located in a different layer.

[0174] In an exemplary embodiment, the island pattern may be located in the same layer as the gate layer, or the island pattern may be located in the same layer as the source / drain metal layer. The specific can be determined according to the data situation and is not limited here.

[0175] In practical applications, the island pattern D and the second wing-shaped wiring 32 may be provided separately.

[0176] In an exemplary embodiment, as shown in FIG. 36, each island pattern D between two adjacent first corners has no overlapping area with the first wing wiring 31 along a direction perpendicular to the substrate.

[0177] 36, the orthogonal projection contour of the first line segment 321 on the substrate is located within the orthogonal projection contour of the first wing-shaped wiring 31 on the substrate. In this case, the orthogonal projection of at least a part of the island pattern D between two adjacent first corners on the substrate and the orthogonal projection portion of the first wing-shaped wiring 31 on the substrate may overlap.

[0178] Illustratively, the orthogonal projection contour of the first line segment 321 on the substrate overlaps with the orthogonal projection contour of the first wing-shaped wiring 31 on the substrate. In this case, the orthogonal projection on the substrate of at least a part of the island pattern D between two adjacent first corners and the orthogonal projection on the substrate of the first wing-shaped wiring 31 do not overlap with each other.

[0179] In practical applications, providing an island pattern between adjacent first corners and / or providing an island pattern between adjacent second corners can improve the stability of the manufacturing process and enhance the uniformity of the line width of the wiring near the first corner and the second corner.

[0180] In some embodiments of the present application, as shown in FIG. 9, a portion of the second wing wiring 32 is located in the same layer, another portion of the second wing wiring 32 is located in the same layer, and the two portions of the second wing wiring 32 are located in different layers.

[0181] For example, as shown in FIG. 9, in the third direction MN, every two first line segments 321 are divided into one set, and each set of first line segment wiring pairs (G1, G2, G3, G4 or G5) includes an outer first line segment W and an inner first line segment N laid out along the third direction MN, and here, for each set of first line segment wiring pairs, the orthogonal projection on the substrate of the second line segment 322 electrically connected to the outer first line segment W overlaps with the orthogonal projection on the substrate of the second line segment 322 electrically connected to the inner first line segment N.

[0182] In an exemplary embodiment, the wing wiring 3 is installed on three conductive film layers, specifically, as shown in FIG. 9, the first wing wiring 31 and the second wing wiring 32 are located on different layers, and the second wing wirings 32 corresponding to the outer first line segment W and the inner first line segment N in each set of first line segments are located on different layers.

[0183] In an exemplary embodiment, when vias are used to connect wires located on different layers, it is necessary to balance the contact resistance between the wrap metals and the occupied design space. The more vias there are, the smaller the contact resistance between the wrap metals on two layers will be, but the more space will be occupied. Taking into consideration the demand for resistance and space, the number of wrap vias is usually two, and the contact resistance is about 1.5Ω.

[0184] For example, the first wing-shaped wiring 31 adopts the same material as the gate (Gate) in the display area AA, i.e., the first wing-shaped wiring 31 and the gate layer are provided in the same layer, a part of the second wing-shaped wiring 32 adopts the same material as the source / drain metal layer (SD) in the display area AA, and another part of the second wing-shaped wiring 32 adopts the same material as the light-shielding layer (LS) in the display area AA, i.e., a part of the second wing-shaped wiring 32 and the source / drain metal layer are provided in the same layer, and another part of the second wing-shaped wiring 32 and the light-shielding layer are provided in the same layer.

[0185] In exemplary embodiments, a single layer of molybdenum (Mo), a stack of molybdenum / aluminum / molybdenum (Mo / Al / Mo), a stack of titanium / aluminum / titanium (Ti / Al / Ti), a bilayer of molybdenum niobium / copper (MoNb / Cu), a bilayer of molybdenum niobium titanium / copper (MoNiTi / Cu), or a bilayer of titanium / copper (Ti / Cu) may be provided as the gate layer.

[0186] In an exemplary embodiment, the gate layer may have a thickness range perpendicular to the substrate of 1000 Å-10000 Å, for example, the thicknesses of the sub-layers of the Mo / Aluminum / Molybdenum (Mo / Al / Mo) stack are 200 Å / 3000 Å / 200 Å, the thicknesses of the sub-layers of the Titanium / Aluminum / Titanium (Ti / Al / Ti) stack are 150 / 4000 / 200 Å, and the thicknesses of the two sub-layers of the Molybdenum Niobium Titanium / Copper (MoNiTi / Cu) bilayer are 200 Å / 4000 Å.

[0187] In an exemplary embodiment, the source / drain metal layer (SD) may be one of a single layer of molybdenum (Mo), a stacked structure of molybdenum / aluminum / molybdenum (Mo / Al / Mo), a stacked structure of titanium / aluminum / titanium (Ti / Al / Ti), a bilayer structure of molybdenum niobium / copper (MoNb / Cu), a bilayer structure of molybdenum niobium titanium / copper (MoNiTi / Cu), or a bilayer structure of titanium / copper (Ti / Cu), where the thickness of the source / drain metal layer (SD) in a direction perpendicular to the substrate may range from 1000 Å to 10000 Å.

[0188] In an exemplary embodiment, the light-shielding layer may be fabricated using a bi-layer aluminum / molybdenum metal layer (Al / Mo), a single layer molybdenum metal layer (Mo), a single layer molybdenum niobium metal layer (MoNb), or a single layer titanium metal layer, and may have a thickness range of 500 Å-2000 Å.

[0189] However, when the wing-shaped wiring 3 is wound on the right side (the other third side edge 103) and bottom side (the second side edge 102) of the driving chip, it may be installed so that the orthogonal projection on the substrate of the second line segment 322 electrically connected to the outer first line segment W overlaps with the orthogonal projection on the substrate of the second line segment 322 electrically connected to the inner first line segment N, and the drawings in this application are drawn and explained using an example in which the wing-shaped wiring 3 is wound on the left side of the driving chip.

[0190] In the embodiment of the present application, for each set of first line segments, the orthogonal projection on the substrate of the second line segment 322 electrically connected to the outer first line segment W and the orthogonal projection on the substrate of the second line segment 322 electrically connected to the inner first line segment N are arranged to overlap, so that the height H of the area occupied by each second wing-shaped wire 32 along the first direction AF can be greatly reduced, and thus the design space can be greatly increased. In practical applications, the line width of the second wing-shaped wire 32 and the distance between two adjacent second wing-shaped wires 32 can be further increased, so that the resistance of the second wing-shaped wire 32 itself can be greatly reduced, thereby realizing high-frequency charging of each pixel unit in the display area AA, increasing the charging rate of the display panel, shortening the charging time, and reducing the power consumption of the display panel.

[0191] Also, since the height H of the area occupied by the second wing-shaped wiring 32 along the first direction AF is small, more fan-out wirings 2 can be installed to be electrically connected to the output terminals 4 by the manner in which the wing-shaped wiring 3 is wound, thereby shortening the length of each fan-out wiring 2 electrically connected to the wing-shaped wiring 3, and further reducing the space occupied by the fan-out wirings 2 in the fan-out region B. Furthermore, as the number of fan-out wirings 2 electrically connected to the output terminals 4 by the manner in which the wing-shaped wiring 3 is wound increases, the dimension of the fan-out region F in the direction toward the fan-out region F along the display area AA can be reduced, which is more advantageous for manufacturing a display panel with a narrow frame.

[0192] In some embodiments of the present application, as shown in FIG. 3 or FIG. 6, the display panel includes a test unit CT and a plurality of test connection wires 6; The test units CT are located on the side of the area in which the output terminals 4 are located away from the display area AA, and the test connection wiring 6 is arranged to connect the test units CT and the output terminals 4, Here, the output terminal 4 electrically connected to the wing-shaped wiring 3 is directly electrically connected to the test connection wiring 6 .

[0193] Illustratively, the test unit CT includes at least one of a display test unit Data CT and a touch test unit VCOM CT. Specifically, the test unit CT may include a display test unit Data CT, or the test unit CT may include a touch test unit VCOM CT T, or the test unit CT includes a display test unit Data CT and a touch test unit VCOM CT at the same time.

[0194] In some embodiments of the present application, a portion of the output terminal 4 is connected to one wing-shaped wiring 3 and one test connection wiring 6, and the orthogonal projection on the substrate of the wing-shaped wiring electrically connected to the same output terminal 4 overlaps with the orthogonal projection on the substrate of the test connection wiring 6.

[0195] In this way, the test connection wiring 6 and the wing-shaped wiring 3 can be installed to be located on different layers, which can save design space between the area where the output terminal 4 is located and the area where the test unit CT is located.

[0196] In some embodiments of the present application, as shown in FIG. 10 , the display panel includes a test unit CT, and the test unit CT is divided into a display test unit Data CT and a touch test unit VCOM CT, at least one of the display test unit Data CT and the touch test unit VCOM CT is located on the side of the display area AA away from the fan-out area F, and the remaining one is located in the fan-out area F or the bind area B.

[0197] For example, both the display test unit Data CT and the touch test unit VCOM CT may be provided on the side of the display area AA away from the fan-out area F.

[0198] For example, one of the display test unit Data CT and the touch test unit VCOM CT may be provided on the side of the display area AA away from the fan-out area F, and the other may be provided in the fan-out area F or the bind area B.

[0199] Specifically, as shown in FIG. 10, when the display test unit Data CT or the touch test unit VCOM CT is located in the fan-out area F, the display test unit Data CT or the touch test unit VCOM CT may be located in the area between the driving chip IC and the MUX circuit, where the MUX circuit is for electrically connecting the signal line in the display area AA and the fan-out wiring 2 in the fan-out area F. For specific details regarding the MUX circuit, reference may be made to the related art, and no further description will be given here.

[0200] When the display test unit Data CT or the touch test unit VCOM CT is located in the bind area B, the display test unit Data CT or the touch test unit VCOM CT may be located in the area where the driving chip IC is located, and the orthogonal projection of the test unit on the substrate and the orthogonal projection of the driving chip IC on the substrate may overlap, or the display test unit Data CT or the touch test unit VCOM CT may be located in any area except the area where the driving chip IC is located in the bind area B.

[0201] Here, FIG. 10 illustrates an example in which the display test unit Data CT is located in the fan-out area F, and the touch test unit VCOM CT is located on the side of the display area AA away from the fan-out area F.

[0202] In the embodiment of the present application, at least one of the display test unit Data CT and the touch test unit VCOM CT is arranged to be located on the side of the display area AA away from the fan-out area F, thereby greatly freeing up the design space of the bind area B or the fan-out area F, thereby providing space to increase the line width of the wiring in the bind area B or the fan-out area F and increase the distance between two adjacent fan-out wirings 2, thereby reducing the resistance of the wiring itself, which is beneficial to realizing high-frequency charging of the display panel, and can increase the charging rate, shorten the charging time, and reduce the power consumption.

[0203] In some embodiments of the present application, the area of ​​the display area AA away from the fan-out area F includes a central area and two corner areas R located on both sides of the central area, and the display test unit Data CT and the touch test unit VCOM CT each include a plurality of test subunits T, and the projected shape of the test subunits T on the substrate is rectangular; Here, each test sub-unit T in the corner region R is arranged around the edge of the display area AA, and the long sides of each rectangle in the corner region R are parallel, as shown in FIG. 11, or there is a preset angle between the long sides of every two adjacent rectangles in the corner region R, as shown in FIG. 12.

[0204] Illustratively, the preset angle may be an acute angle.

[0205] Illustratively, the angle between the long sides of every two adjacent rectangles is the same.

[0206] Exemplarily, the test subunit T may be a test pad (PAD), or the test subunit T may be a switching transistor (STFT), or a part of the test subunit T is a test pad and another part of the test subunit T is a switching transistor.

[0207] However, the projected shape of the test subunit T on the substrate is a rectangle, where the rectangle can be understood as a standard rectangle, or may be a rectangle with rounded corners.

[0208] In the embodiment of the present application, by making the long sides of the projections of the test subunits T on the substrate in the corner regions R parallel to each other, it is possible to reduce the difficulty of design, the difficulty of manufacturing, and the cost.

[0209] In some embodiments of the present application, as shown in FIG. 6 and FIG. 13, the display panel includes a plurality of first signal adjustment lines 11, the first signal adjustment lines 11 are located between the fan-out lines 2 and the wing-shaped lines 3; Here, in the third direction MN, the layout order of each fan-out wiring 2 is different from the layout order of each wing-shaped wiring 3, but the layout order of the ends END1 connected to the fan-out wiring 2 of each first signal adjustment line 11 is the same as the layout order of each fan-out wiring 2, the layout order of the ends END2 connected to the wing-shaped wiring 3 of each first signal adjustment line 11 is the same as the layout order of each wing-shaped wiring 3, and the third direction MN intersects with the first direction AF.

[0210] In practical applications, for the fan-out wiring 2 electrically connected to the wing-shaped wiring 3, the layout order of the multiple fan-out wirings 2 located in the fan-out region F and electrically connected to the wing-shaped wiring 3 does not match the layout order of the multiple wing-shaped wirings 3 located in the bind region B. In order to avoid signal transmission disturbance caused by the mismatch in wiring installation positions, a first signal adjustment line 11 is installed between the fan-out wiring 2 and the wing-shaped wiring 3, and the fan-out wiring 2 is electrically connected to the wing-shaped wiring 3 that matches the signal to be transmitted through the jumper design of the first signal adjustment line 11.

[0211] When the display panel is a TDDI technology display panel, part of the fan-out wiring 2 is display fan-out wiring and part of the fan-out wiring 2 is touch fan-out wiring, so that it is more noticeable that the layout order of the fan-out wiring 2 located in the fan-out area F and electrically connected to the wing-shaped wiring 3 is not aligned with the layout order of the wing-shaped wiring 3 located in the bind area B. In order to match the order of signals transmitted by the fan-out wiring 2 and the wing-shaped wiring 3, whose positional orders do not match, multiple first signal adjustment lines 11 are provided, so that the fan-out wiring 2 is electrically connected to the wing-shaped wiring 3 that matches the signal it is to transmit.

[0212] Specifically, as shown in FIG. 13, the layout order of the multiple fan-out wirings 2 electrically connected to the wing-shaped wiring 3 is the second fan-out wiring 2, the third fan-out wiring 2, the first fan-out wiring 2, the fifth fan-out wiring 2, the sixth fan-out wiring 2, the fourth fan-out wiring 2, the ninth fan-out wiring 2, and so on, and the arrangement order of the ends of the wing-shaped wirings 3 electrically connected to the fan-out wirings 2 is the first wing-shaped wiring 3, the second wing-shaped wiring 3, the third wing-shaped wiring 3, and so on, which is clearly As shown in FIG. 13, the positions and arrangement order of the fan-out wiring 2 and the wing-shaped wiring 3 do not match, and by providing the first signal adjustment line 11 between them, the arrangement order of the ends END1 electrically connected to the fan-out wiring 2 of the first signal adjustment line 11 becomes the same as the layout order of the fan-out wiring 2, and the layout order of the ends END2 connected to the wing-shaped wiring 3 of the first signal adjustment line 11 becomes the same as the layout order of the wing-shaped wiring 3, so that although the wiring positions do not match, the order of the signals to be transmitted matches. However, in FIG. 13, the wing-shaped wiring 3 and the fan-out wiring 2 are not drawn, and only both ends of the first signal adjustment line 11 are marked with number marks indicating the layout order of the wing-shaped wiring 3 and the fan-out wiring 2.

[0213] In some embodiments of the present application, as shown in FIG. 6 and FIG. 13, for each fan-out wiring 2 electrically connected to the output terminal 4 through a region where the first side edge 101 is located, a second signal adjustment line 12 is further provided between the fan-out wiring 2 and the output terminal 4; Here, in the third direction MN, the layout order of each fan-out wiring 2 is different from the layout order of each output terminal 4, the layout order of the ends END1 of each second signal adjustment line 12 connected to the fan-out wiring 2 is the same as the layout order of each fan-out wiring 2, the layout order of the ends END2 of each second signal adjustment line 12 connected to the output terminal 4 is the same as the layout order of each output terminal 4, and the third direction MN and the first direction AF intersect.

[0214] In actual applications, for the fan-out wiring 2 electrically connected to the output terminal 4 (the fan-out wiring 2 of the portion not electrically connected to the wing-shaped wiring 3), the layout order of the fan-out wiring 2 located in the fan-out area F and electrically connected to the output terminal 4 does not match the layout order of the output terminal 4 located in the bind area B. In order to avoid signal transmission disruptions due to a mismatch between the installation positions of the wiring and the output terminal 4, multiple second signal adjustment lines 12 are installed between the fan-out wiring 2 and the output terminal 4, and the fan-out wiring 2 is electrically connected to the output terminal 4 that matches the signal to be transmitted through a jumper design of the multiple second signal adjustment lines 12.

[0215] Specifically, as shown in FIG. 13, the layout order of the multiple fan-out wirings 2 electrically connected to the output terminal 4 is the second fan-out wiring 2, the third fan-out wiring 2, the first fan-out wiring 2, the fifth fan-out wiring 2, the sixth fan-out wiring 2, the fourth fan-out wiring 2, the ninth fan-out wiring 2, and so on, and the arrangement order of the output terminals 4 is the first output terminal 4, the second output terminal 4, the third output terminal 4, and so on. As is clear, the positional arrangement orders of the fan-out wirings 2 and the output terminals 4 do not match, and by providing the second signal adjustment line 12 between them, the arrangement order of the ends END1 electrically connected to the fan-out wirings 2 of the second signal adjustment line 12 becomes the same as the layout order of the fan-out wirings 2, and the layout order of the ends END2 connected to the output terminals 4 of the second signal adjustment line 12 becomes the same as the layout order of the output terminals 4. As a result, although the positional orders of the fan-out wirings 2 and the output terminals 4 do not match, the order of the signals to be transmitted is matched. However, in FIG. 13, the output terminals 4 and the fan-out wiring 2 are not drawn, and only both ends of the second signal adjustment line 12 are marked with number marks indicating the layout order of the output terminals 4 and the fan-out wiring 2.

[0216] In some embodiments of the present application, as shown in FIG. 14, at least a portion of the line segments of each first wing wiring 31 has a serpentine structure.

[0217] At least a portion of the line segment means that, for each of the first wing wirings 31, a portion of the line segment of the first wing wiring 31 may have a serpentine structure, or the entire first wing wiring 31 may have a serpentine structure.

[0218] In an exemplary embodiment, the meandering structure may be formed by connecting a plurality of curved line segments, or the meandering structure may be formed by connecting a plurality of folded line segments.

[0219] In the embodiment of the present application, as shown in FIG. 3 , a part of the fan-out wiring 2 in the fan-out region F is electrically connected to the output terminal 4 of the driving chip through the manner in which the wing-shaped wiring 3 is wound. Therefore, the length d4 of the part of the line segment of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 located in the fan-out region F is significantly shorter than the length d3 of the part of the line segment of the fan-out wiring 2 located in the fan-out region F that is not electrically connected to the wing-shaped wiring 3. The resistance of the fan-out wiring 2 not electrically connected to the wing-shaped wiring 3 is much larger than the resistance of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3. This reduces the resistance consistency of the wiring in the display panel, makes signal transmission unstable, and ultimately leads to uneven brightness of the display panel.

[0220] In the embodiment of the present application, at least a portion of the line segments of each first wing-shaped wiring 31 is arranged to have a serpentine structure, thereby extending the wiring distance from the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 to the output terminal 4, thereby offsetting to a certain extent the shortened length of the fan-out wiring 2 electrically connected to the wing-shaped wiring 3 and improving the resistance matching between different wirings, thereby improving the stability of signal transmission and the brightness uniformity of the display panel.

[0221] However, FIG. 14 illustrates an example in which one of the first wing-shaped wirings 31 has a part of a serpentine structure.

[0222] In some embodiments of the present application, a part of the material of the fan-out wiring 2 is a first conductive material, another part of the material of the fan-out wiring 2 is a second conductive material, and the resistance of the first conductive material is greater than the resistance of the second conductive material; A portion of each fan-out wiring 2 whose material is a first conductive material is electrically connected to a first wing-shaped wiring 3, and a portion of each fan-out wiring 2 whose material is a second conductive material is electrically connected to the first wing-shaped wiring 3, wherein the first wing-shaped wiring 3 electrically connected to the fan-out wiring 2 whose material is the first conductive material has a serpentine structure.

[0223] In an exemplary embodiment, a portion of the fan-out wiring 2 and the source / drain metal layer in the display area AA are fabricated in the same layer and made of the same material, for example, both are aluminum (Al), and another portion of the fan-out wiring 2 and the gate line in the display area AA are fabricated in the same layer and made of the same material, for example, both are molybdenum (Mo).

[0224] In actual applications, when the influence of the resistance of the metal material itself and the line width and thickness of the wiring on the resistance is taken into consideration, the resistance of the partial fan-out wiring 2 manufactured in the same layer as the gate lines in the display area AA is large.

[0225] Here, the partial fan-out wiring 2 manufactured in the same layer as the gate lines in the display area AA has a fan-out wiring 2 electrically connected to the output terminal 4 via the wing-shaped wiring 3, and the partial fan-out wiring 2 manufactured in the same layer as the source / drain metal layer in the display area AA also has a fan-out wiring 2 electrically connected to the output terminal 4 via the wing-shaped wiring 3. Since the partial fan-out wiring 2 manufactured in the same layer as the gate lines in the display area AA has a high resistance, and the difference in wiring length affects the resistance, the resistance difference between this part of the fan-out wiring 2 and other fan-out wiring 2 becomes larger, and therefore at least a part of the line segment of the first wing-shaped wiring 3 electrically connected to the high-resistance fan-out wiring 2 is made into a meandering structure, which on the one hand can improve the resistance matching between different wirings, thereby increasing the stability of signal transmission and improving the luminance uniformity of the display panel, and on the other hand, the problem of increasing the difficulty of the manufacturing process due to making at least a part of the line segments of all the first wing-shaped wirings 3 into a meandering structure is avoided.

[0226] In some embodiments of the present application, as shown in FIG. 16 and FIG. 19, the driving chip IC further includes a plurality of input terminals 5, each of which is laid out along the extending direction of the second side edge 102; The orthogonal projection of the wing-shaped wiring 3 on the substrate of the display panel and the orthogonal projection of the input terminal 5 on the substrate do not overlap with each other.

[0227] In the exemplary embodiment, the distance from each output terminal 4 to the second side edge 102 along the extension direction parallel to the third side edge 103 is not exactly the same.

[0228] For example, as shown in Figures 4 and 16, the distance from each output terminal 4 near both sides of the driver chip to the output terminal 5 along the extension direction parallel to the third side edge 103 is greater than the distance from each output terminal 4 at an intermediate position to the output terminal 5 along the extension direction parallel to the third side edge 103.

[0229] However, for the driver chip shown in FIG. 16, since the space between the area where the output terminal 4 is located and the area where the input terminal 5 is located is limited, the wing-shaped wiring 3 is typically installed so as to pass through the area where the second side edge 102 of the driver chip is located and then electrically connected to the output terminal 4.

[0230] In some embodiments of the present application, as shown in FIG. 3 and FIG. 17 , the fan-out wiring 2 includes a first fan-out segment 201 and a second fan-out segment 202 connected together, the first fan-out segment 201 is electrically connected to a signal line of the display area AA, and the second fan-out segment 202 is electrically connected to an output terminal 4; Here, there is a preset angle between the second fan-out segment 202 and an edge of the display area AA that is closer to the fan-out area F, The sine value of the preset angle is equal to the ratio of the width d5 ​​of the area occupied by all second fan-out segments 202 along a direction perpendicular to their extension direction to half the width d6 of the display area AA along a direction parallel to the first side edge 101.

[0231] In practical applications, the width d5 ​​of the area occupied by the second fan-out segment 202 along a direction perpendicular to its extension direction = the number of second fan-out segments 202 * (the line width of the second fan-out segment 202 + the gap width between two adjacent second fan-out segments 202), i.e., sina = d5 / d6, a = arcsin(d5 / d6).

[0232] In some embodiments of the present application, as shown in Fig. 3, each fan-out wiring 2 has one first inflection point and one second inflection point, the first inflection points of all the fan-out wirings 2 are connected to a first line segment L1, the second inflection points of each fan-out wiring 2 electrically connected to the wing-shaped wiring 3 are connected to a second line segment L2, and the second inflection points of each fan-out wiring 2 not electrically connected to the wing-shaped wiring 3 are connected to a third line segment L3, where the first line segment L1 is parallel to the second line segment L2, and the second line segment L2 is parallel to the third line segment L3. This can increase the regularity of each fan-out wiring 2 in the fan-out region F, reduce the difficulty of design, and reduce the difficulty of the manufacturing technology of the display panel.

[0233] An embodiment of the present application provides a display device including the above-mentioned display panel.

[0234] The display device may be any product or part having a display function, such as a touch display panel, a television including such a touch display panel, a digital camera, a mobile phone, a tablet, etc.

[0235] In the display device of the embodiment of the present application, multiple wing-shaped wires 3 are provided in the bind area B, and the wing-shaped wires 3 are wound in the bind area B (including both the left and right sides and the lower position of the driving chip), so that a part of the fan-out wires 2 is electrically connected to the output terminals 4 of the driving chip through the wing-shaped wires 3, thereby utilizing the area in the bind area B where the driving chip is not installed, shortening the length of the fan-out wires 2 electrically connected to the wing-shaped wires 3, and significantly reducing the space occupied by the fan-out wires 2 in the fan-out area B.
