[0040] Please refer to Figure 3 , Figure 4 and Figure 7 , Figure 3 , Figure 4 and Figure 7 respectively show the top view structural schematic diagram, the cross-sectional structural schematic diagram and another top view structural schematic diagram of the display panel 100 provided by the embodiment according to the present application, from which the components of the embodiment according to the present application and the relative positional relationship of the components can be intuitively seen.

[0041] As shown in Figure 3 , Figure 4 and Figure 7 , the display panel 100 has a display area S1 and a frame area S2 arranged adjacent to each other, and at least includes a plurality of pixel driving units 110, a first wire layer and a second wire layer. Next, in combination with Figure 3 , Figure 4 and Figure 7 , the components in the display panel 100 are described in detail.

[0042] The plurality of pixel driving units 110 are located in the display area S1, and each pixel driving unit 110 at least includes a signal connection line 111.

[0043] It should be noted that, please refer toFigure 5 、 Figure 6a and Figure 6b , Figure 5 、 Figure 6a and Figure 6b respectively show a circuit structure schematic diagram and an exemplary layout of the pixel driving unit 110. As shown in Figure 5 、 Figure 6a and Figure 6b , the display panel 100 further comprises a plurality of second signal wires 140, each of which extends along the second direction X2 and is coupled to the plurality of pixel driving units arranged along the second direction X2 through a plurality of signal connection lines 111.

[0044] Specifically, Figure 5 shows a circuit structure schematic diagram of the pixel driving unit 110 with a possible architecture of 7M1C (MOS transistors M1 to M7 and capacitor C1), it should be understood that the pixel driving unit 110 in the embodiments of the present application can also be of other circuit architectures, which will not be described here in detail.

[0045] In an embodiment according to the present application, the second signal wire 140 can be a reference voltage line (V-reference, Vi), in which case the signal connection line 111 can be a connection wire between the reference voltage line Vi and the seventh MOS transistor M7. Figure 5

[0046] In other embodiments according to the present application, the second signal wire 140 can also be a reset signal line (Reset) or a signal line for other purposes, in which case the signal connection line 111 can be a connection wire between the reset signal line Reset (or a signal line for other purposes) and the MOS transistor coupled thereto. The present application does not limit the specific function of the second signal wire 140.

[0047] The first wire layer (not shown) is located in the display area S1 and comprises at least a plurality of data lines 121 (Data) and a plurality of power signal lines 122 (VDD), each of which extends along the first direction X1 and is coupled to the plurality of pixel driving units arranged along the first direction X1.

[0048] The second wire layer (not shown) is located in the display area S1 and comprises at least a plurality of first fan-out wires 131 and a plurality of first signal wires 132 located on the same straight line and extending along the second direction X2, the first fan-out wire 131 being used to lead out the corresponding data line 121 to the frame area S2, the second direction X2 and the first direction X1 having an included angle, specifically, in the embodiments of the present application, the first direction X and the second direction Y are perpendicular to each other.​

[0049] It should be noted that the display panel has a fan-out area in the frame area, and the driving circuit for driving the pixel unit circuit is arranged in the fan-out area. In some embodiments, the fan-out wire connecting the pixel unit circuit and the driving circuit is also arranged in the fan-out area.

[0050] However, such a setting mode will make the display panel have a wider frame, therefore, the display panel 100 in the embodiments of the present application adopts a FIAA (Fan-out in Active Area) architecture to reduce the size of the frame area S2 of the display panel 100 and realize narrow frame. Specifically, in the display panel 100, some fan-out wires (such as the first fan-out wire 131) located in the display area S1 of the display panel 100 are designed to enable the pixel driving unit 110 to be coupled with the driving circuit located in the frame area S2.

[0051] Further, please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 respectively show a top view structural schematic diagram and a cross-sectional structural schematic diagram of the display panel 100' in an embodiment.

[0052] As shown in Figure 1 and Figure 2 , in the display panel 100' in the FIAA architecture in some embodiments, there is a gap A' between each group of first fan-out wires 131' and the first signal wire 132' in the second wire layer', and the size of the gap A' is large, so that the orthographic projection of the signal connection line 111' in the pixel driving unit 110' on the display panel 100' cannot completely cover the orthographic projection of the gap A' on the display panel 100', as shown in Figure 1 . Specifically, as shown in Figure 2 , in these embodiments, the gap A' includes a first part A1 and a second part A2, wherein the first part A1 coincides with the orthographic projection of the signal connection line 111' on the display panel 100', and the second part A2 does not coincide with the orthographic projection of the signal connection line 111' on the display panel 100'.

[0053] It should be noted that the inventors of the present application have found that, as shown in Figure 2As shown, when viewed from the gap A', due to the signal connection line 111' at the first portion A1 serving as a lower structure blocker, while the second portion A2 is not blocked by the signal connection line 111', the problem of different metal densities of the first portion A1 and the second portion A2 is caused, and due to the regularity of the display panel 100' wiring, the arrangement of the second portion A2 on the display panel 100' also has a certain regularity, thereby causing the display Mura to occur.

[0054] Now back to Figure 3 and Figure 4 In the embodiment of the present application, the gap A is between each group of the first fan-out wire 131 and the first signal wire 132, and the signal connection line 111 has a first orthographic projection on the display panel 100, the data line 121 has a second orthographic projection on the display panel 100, the power signal line 122 has a third orthographic projection on the display panel 100, and the gap A has a fourth orthographic projection on the display panel 100. The present inventor designs that the first orthographic projection or the second orthographic projection or the third orthographic projection covers the fourth orthographic projection, so that when viewed from the gap A of the display panel 100, due to the signal connection line 111 or the data line 121 or the power signal line 122 can completely block the components below, the problem of different metal densities is avoided, thereby effectively preventing the display panel 100 from generating the display Mura during display.

[0055] It needs to be further explained that in the embodiment of the present application, as Figure 1 shown, the two sides of the signal connection line 111 are respectively cut off with the end of the first fan-out wire 131 and the first signal wire 132 close to the gap A.

[0056] Specifically, the size of the gap A in the second direction X2 can be any value between 2 microns and 4 microns, and in the embodiment, the size is 3 microns (um).

[0057] Further, please continue to refer to Figure 1 In the embodiment of the present application, the data line 121 is coupled with the first fan-out wire 131 through the first via B.

[0058] Further, the display panel 100 further comprises a source driving circuit 150 and a third wire layer (not marked), wherein:

[0059] The source driving circuit 150 is located in the frame area S2;

[0060] The third wiring layer is located in the display area S1 and includes at least a plurality of second fan-out wires 161. Each second fan-out wire 161 extends along the first direction X1, and both ends of each second fan-out wire 161 are coupled to the source driving circuit 150 and a corresponding first fan-out wire 131, respectively.

[0061] It should be noted that in the embodiment of the present application, each data line 121 in the first wiring layer is sequentially coupled to a corresponding driving module in the source driving circuit 150 via the first fan-out wire 131 in the second wiring layer and the second fan-out wire 161 in the third wiring layer.

[0062] Further, please continue to refer to Figure 1 In the embodiment of the present application, the first fan-out wires 131 and the first signal wires 132 in each group are arranged to homogenize the metal patterns in the display panel 100, thereby improving the display effect of the display panel 100.

[0063] Further, the inventors have found that if the potential of each first signal wire 132 is set to be floating, the signal transmission in the display panel 100 will be uneven and static electricity will be easily generated, which affects the reliability of the signal transmission in the display panel 100. Therefore, in the embodiment of the present application, the inventors design to couple each first signal wire 132 to a direct current signal in the display panel 100 to solve the above problem.

[0064] Specifically, please continue to refer to Figure 1 The first signal wire 132 can be coupled to a corresponding power signal line 122 via a second via C.

[0066] Further, in order to reduce the voltage drop (IR-Drop) generated during signal transmission in the display panel 100, the wiring coupled to the direct current signal needs to be designed in a grid manner. Specifically, in the embodiment of the present application, as shown in Figure 3 The third wiring layer further includes a plurality of third signal wires 162.
