[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] In addition, in order to better illustrate the present application, numerous specific details are provided in the following detailed description. Those skilled in the art will understand that the present application can be practiced without certain specific details. In some examples, methods and means well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0043] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0044] Current display panels, such as flexible active-matrix organic light-emitting diode (AMOLED) display panels, use a technology called Fanout In AA (FIAA) to narrow the bottom bezel. This technology involves placing some fan-out traces in the display area and then routing the fan-out trace signals to the corresponding display area. For display panels using low-temperature polycrystalline oxide (LTPO) technology, in the prior art, when designing FIAA, reference is made to the design of the LTPO line. Figure 1 and Figure 2 The structural diagram of the display panel shown in FIG. 1 generally divides the fan-out area S1 of the display panel into a first fan-out area S11 and a second fan-out area S12. The first fan-out area S11 and the second fan-out area S12 are symmetrical about the center line of the fan-out area S1. When the center line of the fan-out area S1 coincides with the center line of the display panel, that is, the distance H1 from the fan-out area S1 to the first edge L1 is equal to the distance H2 from the fan-out area S1 to the second edge L2 (see FIG. 1 for details). Figure 1), for example, the first fan-out area S11 and the second fan-out area S12 are each independently provided with 400 fan-out lines, and the fan-out lines of the first fan-out area S11 and the second fan-out area S12 are symmetrically arranged; when the center line of the fan-out area S1 does not coincide with the center line of the display panel, for example, the distance H1 from the fan-out area S1 to the first edge L1 is less than the distance H2 from the fan-out area S1 to the second edge L2 (for details, refer to Figure 2 ), for example, the first fan-out area S11 and the second fan-out area S12 are each independently provided with 400 fan-out lines, and the fan-out lines of the first fan-out area S11 and the second fan-out area S12 cannot be symmetrically arranged, which not only increases the border of the display panel (such as the lower border), but also increases the difference in resistance values ​​of adjacent fan-out lines and the difference between the maximum and minimum resistance values, thereby affecting the display effect of the display panel.

[0045] In view of this, the first aspect of the present application provides a display panel, referring to Figure 3 The structural diagram of the display panel shown in FIG. Figure 4 The display panel shown is a partially enlarged structural schematic diagram, the display panel includes a display area AA and a non-display area NA, the non-display area NA surrounds at least part of the display area AA, the non-display area NA includes a fan-out area S1, and the fan-out area S1 includes a first fan-out area S11 and a second fan-out area S12.

[0046] Optionally, the display panel includes: a plurality of signal lines 100 , a plurality of first fan-out routing lines 210 , and a plurality of second fan-out routing lines 220 .

[0047] Optionally, a plurality of signal lines 100 are located in the display area AA.

[0048] Exemplarily, the signal line includes a data line and / or a power line. For example, the power line includes but is not limited to a high-voltage power line VDD and a low-voltage power line VSS.

[0049] Optionally, a plurality of first fan-out lines 210 are located in the first fan-out area S11, and the first fan-out lines 210 are connected to the signal lines 100. This helps to reduce the width of the display panel frame.

[0050] For example, a first fan-out trace 210 is connected to a corresponding signal line 100 .

[0051] Optionally, the display panel further includes a plurality of third fan-out traces 230 located in the display area AA, and the signal line 100 and the first fan-out trace 210 are connected via the third fan-out traces 230. Some fan-out traces are arranged in the display area AA, which helps to reduce the frame of the display panel.

[0052] For example, the third fan-out trace 230 includes a first portion and a second portion connected to each other, the first portion extends along the second direction y, the second portion extends along the first direction x, the second portion and the first fan-out trace 210 are connected through the first portion, and the signal line 100 and the first portion are connected through the second portion.

[0053] Optionally, a plurality of second fan-out lines 220 are located in the second fan-out area S12, and the second fan-out lines 220 are connected to the signal line 100. This helps to reduce the width of the display panel frame.

[0054] For example, a second fan-out trace 220 is connected to a corresponding signal line 100 .

[0055] Optionally, the display panel further includes a plurality of fourth fan-out traces 240 located in the display area AA, and the signal line 100 and the second fan-out trace 220 are connected via the fourth fan-out traces 240. Some fan-out traces are arranged in the display area AA, which helps to reduce the frame of the display panel.

[0056] For example, the fourth fan-out trace 240 includes a third portion and a fourth portion connected to each other, the third portion extends along the second direction y, the fourth portion extends along the first direction x, the fourth portion is connected to the second fan-out trace 220 through the third portion, and the signal line 100 is connected to the third portion through the fourth portion.

[0057] Optionally, the first fan-out area S11 and the second fan-out area S12 are arranged along the first direction x.

[0058] In which, in the first direction x, the display panel has a first edge L1 and a second edge L2 arranged opposite to each other, the first fan-out area S11 is close to the first edge L1, and the distance H1 from the edge of the first fan-out area S11 away from the second fan-out area S12 to the first edge L1 is smaller than the distance H2 from the edge of the second fan-out area S12 away from the first fan-out area S11 to the second edge L2; the number of the second fan-out lines 220 is greater than the number of the first fan-out lines 210. According to the display panel provided in the embodiment of the present application, the distance from the edge of the first fan-out area S11 away from the second fan-out area S12 to the first edge L1 is shorter than the distance from the edge of the second fan-out area S12 away from the first fan-out area S11 to the second edge L2. The number of second fan-out lines 220 is greater than the number of first fan-out lines 210, so that the resistance difference between adjacent second fan-out lines 220 in the second fan-out area S12 can be relatively small. For example, the resistance difference between adjacent second fan-out lines 220 can be equivalent to the resistance difference between adjacent first fan-out lines 210. At the same time, the difference between the maximum resistance value and the minimum resistance value in the second fan-out lines 220 can also be reduced, which is conducive to achieving a narrow frame design effect.

[0059] In the prior art, referring to Figure 5In the partially enlarged structural diagram of the display panel shown, a distance H1 from the edge of the first fan-out area S11 away from the second fan-out area S12 to the first edge L1 is smaller than a distance H2 from the edge of the second fan-out area S12 away from the first fan-out area S11 to the second edge L2. However, the number of second fan-out traces 220 is equal to the number of first fan-out traces 210. The first fan-out area S11 and the second fan-out area S12 are symmetrical about the midline of the fan-out area S1. That is, in the first direction x, the width W1 of the first fan-out area S1 is equal to the width W2 of the second fan-out area S2. This makes the trace length of the second fan-out trace 220 longer, which will increase the border of the display panel (for example, the bottom border), increase the resistance difference between adjacent second fan-out traces 220, and increase the difference between the maximum resistance value and the minimum resistance value among the multiple second fan-out traces 220. The display panel of the present application has a large number of second fan-out traces 220, and the routing distance of each second fan-out trace 220 is relatively short, which helps to reduce the bezel of the display panel. The difference in resistance values ​​between adjacent second fan-out traces 220 is small, and the difference between the maximum resistance value and the minimum resistance value of multiple second fan-out traces 220 is small. In a specific embodiment of the present application, the bezel length of the display panel of the present application can be reduced by approximately 100μm compared to the bezel length of display panels in the prior art.

[0060] Exemplarily, the signal line 100 extends along the second direction y, and the first direction x intersects the second direction y. For example, the first direction x and the second direction y are perpendicular to each other.

[0061] In one embodiment, the number of second fan-out lines 220 is 4% to 10% greater than the number of first fan-out lines 210, for example, 4%, 5%, 6%, 7%, 8%, 9%, or 10%. This helps shorten the length of the second fan-out lines 220 and reduce the bezel of the display panel. The difference in resistance values ​​between adjacent second fan-out lines 220 is small, and the difference between the maximum resistance value and the minimum resistance value among the plurality of second fan-out lines 220 is small.

[0062] It should be noted that the number of second fan-out traces 220 being 4% to 10% greater than the number of first fan-out traces 210 refers to the ratio of the difference between the number of second fan-out traces 220 and the number of first fan-out traces 210 to the number of first fan-out traces 210 .

[0063] It can be understood that the ratio of the difference between the number of second fan-out lines 220 and the number of first fan-out lines 210 to the number of first fan-out lines 210 may also be less than 4%. In this case, the effect of reducing the display panel border is relatively insignificant; the ratio of the difference between the number of second fan-out lines 220 and the number of first fan-out lines 210 to the number of first fan-out lines 210 may also be greater than 10%. In this case, the number of second fan-out lines 220 is large, the routing is more complicated, and it is relatively not conducive to reducing the display panel border.

[0064] For example, the sum of the number of second fan-out traces 220 and the number of first fan-out traces 210 may be equal to the number of signal traces 100. In this case, all signal traces 100 are connected to the driver chip through the first fan-out traces 210 and the second fan-out traces 220, respectively.

[0065] For another example, the sum of the number of second fan-out traces 220 and the number of first fan-out traces 210 is less than the number of signal lines 100. When the sum of the number of second fan-out traces 220 and the number of first fan-out traces 210 is less than the number of signal lines 100, after the signal lines 100 near the first edge L1 are connected to the first fan-out traces 210, the first fan-out traces 210 are connected to the driver chip. After the signal lines 100 near the second edge L2 are connected to the second fan-out traces 220, the second fan-out traces 220 are connected to the driver chip. The remaining signal lines 100 are directly connected to the driver chip.

[0066] In one embodiment, in the first direction x, the width W1 of the first fan-out area S11 is smaller than the width W2 of the second fan-out area S12. Thus, the widths of the first fan-out area S11 and the second fan-out area S12 correspond to the number of first fan-out traces 210 and the number of second fan-out traces 220, respectively. This ensures that the spacing between adjacent first fan-out traces 210 and the spacing between adjacent second fan-out traces 220 are similar, which helps improve routing yield.

[0067] In one embodiment, referring to Figure 6 In the first direction x, the display area AA has a third edge L3 and a fourth edge L4 that are opposite to each other. The first fan-out area S11 is close to the third edge L3. A distance H3 from an edge of the first fan-out area S11 away from the second fan-out area S12 to the third edge L3 is smaller than a distance H4 from an edge of the second fan-out area S12 away from the first fan-out area S11 to the fourth edge L4.

[0068] In one embodiment, referring to Figure 7In the structural diagram of the display panel shown, multiple first fan-out lines 210 include a first sub-fan-out line 211, which is adjacent to the first edge L1 and forms a first angle α1 with the first direction x; multiple second fan-out lines 220 include a second sub-fan-out line 221, which is adjacent to the second edge L2 and forms a second angle α2 with the first direction x. The difference between the first angle α1 and the second angle α2 is 0-10%, for example, 0, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10%. As a result, the first angle α1 and the second angle α2 are not much different, so that the lengths of the first sub-fan-out line 211 and the second sub-fan-out line 221 are not much different, which is conducive to reducing the bezel of the display panel.

[0069] Exemplarily, the first angle α1 may be greater than the second angle α2, the first angle α1 may be equal to the second angle α2, or the first angle α1 may be smaller than the second angle α2.

[0070] It should be noted that the difference between the first angle α1 and the second angle α2 of 0 to 10% refers to the ratio of the absolute value of the difference between the first angle α1 and the second angle α2 to the first angle α1, or the ratio of the absolute value of the difference between the first angle α1 and the second angle α2 to the second angle α2.

[0071] Optionally, the length of the first sub-fan-out line 211 differs from the length of the second sub-fan-out line 221 by 0-10%, for example, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10%. Thus, the length of the first sub-fan-out line 211 and the second sub-fan-out line 221 are not much different, which helps to reduce the border of the display panel.

[0072] Exemplarily, the length of the first sub-fan-out line 211 may be equal to the length of the second sub-fan-out line 221 , the length of the first sub-fan-out line 211 may be greater than the length of the second sub-fan-out line 221 , and the length of the first sub-fan-out line 211 may be less than the length of the second sub-fan-out line 221 .

[0073] It should be noted that the difference of 0% to 10% between the length of the first sub-fan-out line 211 and the length of the second sub-fan-out line 221 refers to the ratio of the absolute value of the difference between the length of the first sub-fan-out line 211 and the length of the second sub-fan-out line 221 to the length of the first sub-fan-out line 211, or the ratio of the absolute value of the difference between the length of the first sub-fan-out line 211 and the length of the second sub-fan-out line 221 to the length of the second sub-fan-out line 221.

[0074] Exemplarily, the first angle α1 is equal to the second angle α2. Thus, the lengths of the first sub-fan-out line 211 and the second sub-fan-out line 221 are almost equal, which helps to reduce the frame of the display panel.

[0075] For example, the length of the first sub-fan-out line 211 is equal to the length of the second sub-fan-out line 221, and the first angle α1 is equal to the second angle α2. At this time, in the second direction y, the frame lengths corresponding to the first sub-fan-out line 211 and the second sub-fan-out line 221 are equal, so that the display panel will hardly be affected by the offset of the fan-out area S1.

[0076] In one embodiment, referring to Figure 8 In the structural schematic diagram of the display panel shown, multiple first fan-out lines 210 include a third sub-fan-out line 212. In the first direction x, the third sub-fan-out line 212 and the first sub-fan-out line 211 are located at opposite ends of the first fan-out area S11, and the angle between the third sub-fan-out line 212 and the first direction x is a third angle α3; multiple second fan-out lines 220 include a fourth sub-fan-out line 222. In the first direction x, the fourth sub-fan-out line 222 and the second sub-fan-out line 221 are located at opposite ends of the second fan-out area S12, and the angle between the fourth sub-fan-out line 222 and the first direction x is a fourth angle α4. The difference between the third angle α3 and the fourth angle α4 is 0-10%, for example, it can be 0, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9% or 10%, etc. Therefore, the third included angle α3 is not much different from the fourth included angle α4, so that the lengths of the third sub-fan-out line 212 and the fourth sub-fan-out line 222 are not much different, which is beneficial to reducing the frame of the display panel.

[0077] Exemplarily, the third angle α3 may be greater than the fourth angle α4, the third angle α3 may be equal to the fourth angle α4, or the third angle α3 may be smaller than the fourth angle α4.

[0078] It should be noted that the difference between the third angle α3 and the fourth angle α4 of 0 to 10% refers to the ratio of the absolute value of the difference between the third angle α3 and the fourth angle α4 to the third angle α3, or the ratio of the absolute value of the difference between the third angle α3 and the fourth angle α4 to the fourth angle α4.

[0079] Optionally, the length of the third sub-fan-out line 212 differs from the length of the fourth sub-fan-out line 222 by 0-10%, for example, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10%. Thus, the length of the third sub-fan-out line 212 and the fourth sub-fan-out line 222 are not much different, which helps to reduce the border of the display panel.

[0080] Exemplarily, the length of the third sub-fan-out line 212 may be equal to the length of the fourth sub-fan-out line 222 , the length of the third sub-fan-out line 212 may be greater than the length of the fourth sub-fan-out line 222 , or the length of the third sub-fan-out line 212 may be less than the length of the fourth sub-fan-out line 222 .

[0081] It should be noted that the difference of 0 to 10% between the length of the third sub-fan-out line 212 and the length of the fourth sub-fan-out line 222 refers to the ratio of the absolute value of the difference between the length of the third sub-fan-out line 212 and the length of the fourth sub-fan-out line 222 to the length of the third sub-fan-out line 212, or the ratio of the absolute value of the difference between the length of the third sub-fan-out line 212 and the length of the fourth sub-fan-out line 222.

[0082] Exemplarily, the third angle α3 is equal to the fourth angle α4. Thus, the lengths of the third sub-fan-out line 212 and the fourth sub-fan-out line 222 are almost equal, which helps to reduce the frame of the display panel.

[0083] For example, the length of the third sub-fan-out line 212 is equal to the length of the fourth sub-fan-out line 222, and the third angle α3 is equal to the fourth angle α4. At this time, in the second direction y, the border lengths corresponding to the third sub-fan-out line 212 and the fourth sub-fan-out line 222 are equal, so that the display panel will hardly be affected by the offset of the fan-out area S1.

[0084] It can be understood that the length of the first fan-out line 210 located between the first sub-fan-out line 211 and the third sub-fan-out line 212 is less than the length of the first sub-fan-out line 211 and the third sub-fan-out line 212; the length of the second fan-out line 220 located between the second sub-fan-out line 221 and the fourth sub-fan-out line 222 is less than the length of the second sub-fan-out line 221 and the fourth sub-fan-out line 222.

[0085] In one embodiment, referring to Figure 9 As shown in the structural diagram of the display panel, the display panel further includes a bending area S2. The fan-out area S1 is used to connect the signal line in the display area AA to the bending area S2. The bending area S2 is located in the non-display area NA.

[0086] It can be understood that the bending area S2 bends toward the backlight side of the display panel to connect the wiring in the fan-out area S1 with the driver chip.

[0087] Optionally, the bending area S2 is located on a side of the fan-out area S1 away from the display area AA.

[0088] Optionally, the fan-out area S1 and the bending area S2 are arranged along the second direction y, and the first direction x intersects the second direction y.

[0089] It is understood that the display panel of the present embodiment reduces the resistance difference between adjacent second fan-out traces 220 by increasing the number of second fan-out traces 220 located in the second fan-out region S12, while also reducing the difference between the maximum and minimum resistance values ​​of the second fan-out traces 220. This facilitates achieving a narrow-frame design. Furthermore, the display panel of the present embodiment is compatible with existing display panel manufacturing processes, without incurring additional costs.
