[0006] The display area includes a plurality of first power signal lines, the first power signal lines extending along a first direction, and the plurality of first power signal lines arranged along a second direction, wherein the first direction and the second direction intersect;

[0007] The non-display area includes a power bus and a power lead, and the power lead is arranged in series between the power bus and the power signal terminal;

[0008] The power bus includes a first bus section and a second bus section, and along the first direction, the first bus section is connected to the power lead line;

[0009] The display area includes a first display area and a second display area.

Along the first direction, the projection of the first display area on the power bus overlaps with the first bus segment, and the projection of the second display area on the power bus overlaps with the second bus segment. Furthermore, the first bus segment is connected to the power lead lines, i.e., the projection of the first display area on the power bus is closer to the power lead lines than the projection of the second display area on the power bus. Consequently, the projection of the first display area on the power bus overlaps with the first bus segment, and the projection of the second display area on the power bus overlaps with the second bus segment. By adjusting the number of connections between the power signal lines and the bus in different display areas, the display uniformity of the display panel is ensured and the display effect of the display panel is improved.

It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0028] Figure 1 is a structural diagram of a display panel provided by an embodiment of the present invention, Figure 2 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 1 and Figure 2As shown, an embodiment of the present invention provides a display panel 10, which includes a display area 100 and a non-display area 200, wherein the non-display area 200 is located on at least one side of the display area 100; the display area 100 includes a plurality of first power signal lines 110, the first power signal lines 110 extending along a first direction X, and the plurality of first power signal lines 110 arranged along a second direction Y, wherein the first direction X and the second direction Y intersect; the non-display area 200 includes a power bus 210 and a power lead 220, wherein the power lead 220 is arranged in series between the power bus 210 and the power signal terminal 230; the power bus 210 includes a first bus segment 211 and a second bus segment 212. Line division 212, along the first direction X, the first bus division 211 is connected to the power lead 220; the display area 100 includes a first display area 120 and a second display area 130, along the first direction X, the projection of the first display area 120 on the power bus 210 has an overlapping area with the first bus division 211, and the projection of the second display area 130 on the power bus 210 has an overlapping area with the second bus division 212, and the first power signal line 110 located in the first display area 120 is at most partially electrically connected to the first bus division 211, and the first power signal line 110 located in the second display area 130 is at least partially electrically connected to the second bus division 212.

[0029] The display panel 10 includes a display area 100 and a non-display area 200. The non-display area 200 may be a border region located to one side of the display area 100. The embodiment of the present invention does not specifically limit the positional relationship between the display area 100 and the non-display area 200. The display area 100 is used to implement the display function of the display panel 10, while the non-display area 200 is used to set a drive unit, etc., for driving the display area 100 to implement the display function.

[0030] For further reference, Figure 1 and Figure 2 As shown, the display area 100 includes a first power signal line 110. The first power signal line 110 is used to transmit a power signal and provide the power signal to the sub-pixels in the display area 100 for achieving light-emitting display, thereby ensuring the display effect of the display panel 10. Specifically, there are multiple first power signal lines 110 in the display area 100, and the first power signal lines 110 extend along a first direction X. The multiple first power signal lines 110 are arranged along a second direction Y, where the first direction X is the direction from the display area 100 to the non-display area 200. In the display area 100, by arranging the first power signal lines 110 in a regular and balanced array, a balanced display effect is achieved in the display area 100.

[0031] Furthermore, the non-display area 200 includes a power bus 210, power lead lines 220, and a power signal terminal 230. The power signal terminal 230 is electrically connected to the power lead lines 220, which are in turn electrically connected to the power bus 210. The power bus 210 is electrically connected to the first power signal line 110. This allows the power signal (PVDD) transmitted by the power signal terminal 230 to be expanded and transmitted to the power bus 210, facilitating the multiple first power signal lines 110 in the display area 100 to obtain the power signal, thereby achieving the display function of the display panel 10. The power signal terminal 230 can be a connection terminal such as a metal pad, which is used to bind and electrically connect to the power signal output terminal in the flexible circuit to receive the power signal transmitted by the flexible circuit board.

[0032] Furthermore, the power bus 210 includes a first bus segment 211 and a second bus segment 212. Figure 1 and Figure 2 As shown, along the first direction X, i.e., the direction from the display area 100 toward the non-display area 200, the first bus segment 211 is connected to the power lead 220, while the second bus segment 212 is not connected to the power lead 220. The power signal output by the power signal terminal 230 is first directly transmitted to the first bus segment 211, and then transmitted to the second bus segment 212 through the first bus segment 211. That is, the first bus segment 211 is closer to the power lead 220 than the second bus segment 212, and the first bus segment 211 receives the power signal earlier than the second bus segment 212. The first bus segment 211 is the output segment of the power signal in the second bus segment 212.

[0033] It should be noted that the first bus division 211 is connected to the power lead 220. The first bus division 211 and the power lead 220 can be arranged on the same layer and directly connected, or the first bus division 211 and the power lead 220 can be arranged on different layers and electrically connected through connecting vias. The embodiment of the present invention does not limit this.

[0034] For further reference, Figure 1 and Figure 2As shown, the display area 100 includes a first display area 120 and a second display area 130. Along the first direction X, that is, the direction in which the display area 100 points to the non-display area 200, at the power bus 210, the projection of the first display area 120 overlaps with the first bus division 211, that is, there is at least one straight line extending along the first direction X and passing through the first display area 120 and the first bus division 211. The projection of the second display area 130 overlaps with the second bus division 212, that is, there is at least one straight line extending along the first direction X and passing through the second display area 130 and the second bus division 212. As mentioned above, since the first bus section 211 in area B is connected to the power lead 220, the loss of the power signal transmitted in the first bus section 211 is smaller than the loss of the power signal transmitted in the second bus section 212. Based on the different positions of the first bus section 211 and the second bus section 212, that is, the different relative distances from the power lead 220, the power signal losses generated are different, which will cause the power signal transmitted to the first power signal line 110 to be different, thereby affecting the display balance of the display panel 10.

[0035] Specifically, the first power signal line 110 located in the first display area 120 is electrically connected to the first bus segment 211 at most. Figure 1 As shown, there is a situation where part of the first power signal line 110 in the first display area 120 is electrically connected to the first bus sub-portion 211, and part of the first power signal line 110 in the first display area 120 is not connected to the first bus sub-portion 211, that is, it is insulated. Figure 2 As shown, there is also a situation where all the first power signal lines 110 in the first display area 120 are not connected to the first bus sub-portion 211, that is, they are insulated. However, the first power signal lines 110 in the second display area 130 are at least partially electrically connected to the second bus sub-portion 212, that is, Figure 1 and Figure 2As shown, some of the first power signal lines 110 in the second display area 130 are electrically connected to the second bus segment 212. At the same time, some of the first power signal lines 110 in the second display area 130 are insulated from the second bus segment 212 (not specifically shown in the figure). In other words, due to the difference in position between the first bus segment 211 and the second bus segment 212 and the power lead 220, the second bus segment 212 is farther away from the power lead 220, resulting in greater power loss. Specifically, the voltage generated at the first bus segment 211 is higher than the voltage generated at the second bus segment 212. By isolating the first bus segment 211 from part of the first power signal line 110 and not being electrically connected to all of the first power signal lines 110, at least a part of the first power signal lines 110 receives power signals transmitted by other transmission channels, thereby increasing the loss of the first power signal line 110 in the first display area 120, thereby reducing the voltage strength of the power signal on the first power signal line 110 in the first display area 120, and thus balancing the power signal strength in the first display area 120 and the second display area 130, ensuring that the power signal obtained by the first power line signal 110 in the display area 100 is balanced, and thus ensuring the overall display balance of the display panel 10.

[0036] It should be noted that the first power signal line 110 located in the first display area 120, at least part of the first power signal line 110 that is not directly electrically connected to the first bus division 211 can access the power signal through other means, and the power signal accessed by at least part of the first power signal line 110 that is not directly electrically connected to the first bus division 211 has a larger loss than the power signal accessed by at most part of the first power signal line 110 that is directly electrically connected to the first bus division 211. This increases the loss of the first power signal line 110 in the first display area 120, thereby balancing the power signals in the first display area 120 and the second display area 130, ensuring that the power signals obtained by the first power line signal 110 in the display area 100 are balanced, thereby ensuring the overall display balance of the display panel 10. It should also be noted that Figure 1 For example, a display panel including two power leads 220 is used for illustration. Correspondingly, the power bus 210 includes two first bus sections 211, and the display area 100 includes two first display areas 120. The embodiment of the present invention does not limit the number of power leads. In other embodiments, the number of power leads can be one, three, or more. Corresponding to the number of power leads, the number of first bus sections and first display areas can be one, three, or more. Furthermore, the embodiment of the present invention does not limit the number of power signal lines in the first display area and the second display area. The number of power signal lines can be related to the display resolution of the display panel, for example, each power signal line corresponds to a column of sub-pixels.

[0037] In summary, in the display panel provided by the embodiments of the present invention, at most a portion of the first power signal line located in the first display area is electrically connected to the first bus segment, while at least a portion of the first power signal line located in the second display area is electrically connected to the second bus segment. This means that by adjusting the number and type of connections between the power signal lines and the bus in different display areas, the display uniformity of the display panel is ensured, thereby improving the display quality of the display panel.

[0038] Continue to refer Figure 1 As shown, among the plurality of first power signal lines 110 located in the first display area 120 , some of the first power signal lines 110 are electrically connected to the first bus segment 211 .

[0039] Among them, reference Figure 1 In the B region, the first bus segment 211 is electrically connected to a portion of the first power signal line 110 , and the first bus segment 211 is not electrically connected to a portion of the first power signal line 110 . Specifically, the power signal output by the power signal terminal 230 is first directly transmitted to the first bus division 211, then transmitted to the second bus division 212 through the first bus division 211, and then transmitted to the first power signal line 110 through the first bus division 211 and the second bus division 212 respectively. However, the first power signal lines 110 in the first display area 120 are not all electrically connected to the first bus division 211, that is, in the first display area 120, not all first power signal lines 110 receive power signals with lower loss. At least some of the first power signal lines 110 in the first display area 120 receive power signals transmitted from other transmission channels, which increases the transmission loss of the power signal in the first display area, thereby reducing the voltage strength of the power signal in the first display area 120, thereby ensuring that the power signal obtained by the first power line signal 110 in the entire display area 100 is balanced, thereby ensuring the overall display balance of the display panel 10.

[0040] Figure 3 yes Figure 1 An enlarged schematic diagram of area B in the middle, refer to Figure 1 and Figure 3 As shown, the multiple first power signal lines 110 located in the first display area 120 include first sub-power signal lines 110A electrically connected to the first bus division 211 and second sub-power signal lines 110B insulated from the first bus division 211; the number of second sub-power signal lines 110B between any two adjacent first sub-power signal lines 110A is the same.

[0041] Specifically, refer to Figure 1 and Figure 3 As shown, Figure 3 express Figure 1A schematic diagram of the structure of the enlarged area B in the middle shows that the first power signal line 110 includes a first sub-power signal line 110A and a second sub-power signal line 110B. The first sub-power signal line 110A is electrically connected to the first bus segment 211, while the second sub-power signal line 110B is insulated from the first bus segment 211. This means that by isolating the second sub-power signal line 110B from the first bus segment 211, some of the multiple first power signal lines 110 located in the first display area 120 are electrically connected to the first bus segment 211. In other words, the first sub-power signal lines 110 can receive power signals through the first bus segment 211, while the second sub-power signal lines 110 can receive power signals from other transmission channels. This reduces the transmission loss of the power signal in the first display area 120, thereby reducing the voltage strength of the power signal in the first display area 120 and ensuring display balance across the display area 100 of the display panel 10.

[0042] Furthermore, the number of second sub-power signal lines 110B between any two adjacent first sub-power signal lines 110A is the same, which can ensure that the second sub-power signal lines 110B between the first sub-power signal lines 110A are arranged in a simple manner, and the intensity distribution of the power signal in the first display area 120 is balanced, ensuring the overall display balance of the first display area 120. For example, referring to Figure 3 As shown, any two adjacent first sub-power signal lines 110A may include a second sub-power signal line 110B, and the lines are arranged periodically. Figure 3 For illustration only, there are actually many different ways to arrange the second sub-power signal lines 110B between the first sub-power signal lines 110A. The embodiment of the present invention does not specifically limit the number of the first sub-power signal lines 110A and the second sub-power signal lines 110B.

[0043] Figure 4 yes Figure 1 Another enlarged schematic diagram of area B, see Figure 1 and Figure 4 As shown, the multiple first power signal lines 110 located in the first display area 120 include a first sub-power signal line 110A electrically connected to the first bus division 211 and a second sub-power signal line 110B insulated from the first bus division 211; two adjacent first sub-power signal lines 110A and the second sub-power signal line 110B between the two first sub-power signal lines 110A form a first power signal line group 110C; there are two groups of first power signal line groups 110C with different numbers of second sub-power signal lines 110B.

[0044] The first display area 120 includes a plurality of first power signal line groups 110C, and the first power signal line group 110C includes two adjacent first sub-power signal lines 110A and a second sub-power signal line 110B between the two first sub-power signal lines 110A. Figure 4 As shown, the number of second sub-power signal lines 110B in different first power signal line groups 110C is diverse, that is, the first power signal line groups 110C are diverse, thereby breaking the regular arrangement of the first power signal lines 110, avoiding the appearance of regular bright and dark patterns in the display area 100, and ensuring the overall display effect of the display panel 10.

[0045] Exemplary, reference Figure 4 As shown in the figure, multiple first power signal line groups 110C are used as an example for illustration, namely, first power signal line groups 110C located in regions C1, C2, and C3. The first power signal line group 110C in region C1 includes two adjacent first sub-power signal lines 110A and two second sub-power signal lines 110B between the two first sub-power signal lines 110A. The first power signal line group 110C in region C2 includes two adjacent first sub-power signal lines 110A and one second sub-power signal line 110B between the two first sub-power signal lines 110A. The first power signal line group 110C in region C3 includes two adjacent first sub-power signal lines 110A and three second sub-power signal lines 110B between the two first sub-power signal lines 110A. This embodiment of the present invention merely reflects the different numbers of second sub-power signal lines 110B in the two first power signal line groups 110C, but does not limit the specific numbers.

[0046] Figure 5 yes Figure 1 Another enlarged schematic diagram of area B, see Figure 1 and Figure 5 As shown, in any two first power signal line groups 110C, the number of second sub-power signal lines 110B in the first power signal line group 110C close to the center d of the first display area 120 is a first number, and the number of second sub-power signal lines 110B in the first power signal line group 110C away from the center d of the first display area 120 is a second number; the second number is smaller than the first number, and the center d of the first display area 120 extends along the first direction X and coincides with the center of the power lead 220.

[0047] Specifically, refer to Figure 5As shown, the first display area 120 includes a center d, and the extension line of the center d of the first display area 120 coincides with the power lead 220, that is, the center of the first display area 120 is closest to the power lead 220. Further, the first display area 120 includes a plurality of first power signal line groups 110C, that is, there is a first power signal line group 110C ( Figure 5 The first power signal line group 110C (a center area C5) and a first power signal line group 110C (a side away from the center d of the first display area 120) Figure 5 middle area C4).

[0048] Figure 5 There is a difference in the number of second sub-power signal lines 110B in the first power signal line group 110C corresponding to the middle regions C4 and C5. Specifically, the number of second sub-power signal lines 110B in the power signal line group 110C closer to the center d of the first display area 120 is greater than the number of second sub-power signal lines 110B in the power signal line group 110C farther from the center d of the first display area 120. In other words, the number of second sub-power signal lines 110B in the first display area 120 exhibits a gradual transition trend, with more second sub-power signal lines 110B near the center d and fewer second sub-power signal lines 110B farther from the center d. Furthermore, when the number of second sub-power signal lines 110B in the second display area 130 is less than that in the first display area 120, a more refined design of the second sub-power signal lines 110B in the first display area 120 ensures a smoother transition between the first display area 120 and the second display area 130, avoiding significant brightness differences in the display panel 10 and improving the overall balanced display effect of the display panel 10.

[0049] Continue to refer Figure 2 As shown, the plurality of first power signal lines 110 located in the first display area 120 are all insulated from the first bus segment 2111 .

[0050] Among them, reference Figure 2 In area B, the first bus sub-portion 211 is insulated from all the first power signal lines 110, that is, the first power signal lines 110 in area B are all second sub-power signal lines 110B. At this time, the power signals obtained by the first power signal lines 110 in the first display area 120 are not directly transmitted through the first bus sub-portion 211.

[0051] Furthermore, the first power signal lines 110 in the first display area 120 are all set to second sub-power signal lines 110B, thereby reducing the voltage strength of the power signal transmitted through the first power signal line 110 in the first display area 120, and can balance the voltage strength of the power signal in the first display area 120 and the second display area 130, ensuring that the power signal obtained by the first power line signal 110 in the entire display area 100 is balanced, thereby ensuring the overall display balance of the display panel 10, and at the same time, can also simplify the connection process between the first power signal line 110 in the first display area 120 and the first bus division 211, thereby simplifying the preparation process and preparation cost of the display panel 10 as a whole.

[0052] Continue to refer Figure 1 and Figure 2 As shown, the display area 100 further includes a plurality of second power signal lines 140, which extend along the second direction Y and are arranged along the first direction X. The first power signal lines 110 and the second power signal lines 140 are arranged in different layers, and at least one second power signal line 140 is electrically connected to the plurality of first power signal lines 110 arranged along the second direction Y through vias 150. Furthermore, the first power signal line 110 insulated from the first bus segment 211 is electrically connected to the second power signal lines 140 through the vias 150.

[0053] Specifically, the display area 100 includes a plurality of first power signal lines 110 and a plurality of second power signal lines 140. The first power signal lines 110 extend along a first direction X, and the second power signal lines 140 extend along a second direction Y. The first power signal lines 110 are arranged along the second direction Y, and the second power signal lines 140 are arranged along the first direction X. That is, the display area 100 includes a plurality of first power signal lines 110 and a plurality of second power signal lines 140 arranged horizontally and vertically.

[0054] Specifically, the first power signal line 110 and the second power signal line 140 are located in different metal film layers of the display area 100, thereby ensuring that the first power signal line 110 and the second power signal line 140 are laid out neatly and do not interfere with each other. Furthermore, the first power signal line 110 and the second power signal line 140 are both used to transmit power signals. The vias 150 are used to electrically connect the first power signal line 110 and the second power signal line 140 in different film layers, thereby reducing power signal transmission losses.

[0055] For further reference, Figure 1 and Figure 2As shown, the first power signal line 110 insulated from the first bus division 211 is electrically connected to the second power signal line 140 through the via 150, that is, there is a first power signal line 110 electrically connected to the first bus division 211, so as to directly obtain the power signal through the first bus division 211; at the same time, there is also a first power signal line 110 insulated from the first bus division 211, which can transmit the second power signal line 120 through the first power signal line 110 that has obtained the power signal through the via 150, and then transmit it to the first power signal line 110 insulated from the first bus division 211 through the second power signal line 120 and the via 150. On the basis of ensuring the balance of the power signal obtained in the entire display area 100, it is ensured that each first power signal line 120 transmits a power signal, and the pixel circuit (not shown in the figure) electrically connected to each first power signal line 120 can receive the power signal and then generate a driving current to drive the light-emitting element to emit light, thereby ensuring the overall display balance of the display panel 10.

[0056] Exemplary, reference Figure 1 and Figure 2 As shown in the figure, only one via 150 is shown on the second power signal line 140; the vias 150 on the other second power signal lines 140 are not shown one by one. The vias 150 located in the first display area 120 ensure that the first power signal line 110, which is insulated from the first bus segment 211, can receive the power signal. The vias 150 located in the second display area 130 ensure that the power signal is transmitted to the second power signal line 140 via the first power signal line 110. This embodiment of the present invention does not specifically limit the number and location of the vias 150.

[0057] Figure 6 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 6 As shown, among the multiple second power signal lines 140, there are two second power signal lines 140 (141 and 142), the second power signal line 140 close to the non-display area 200 is insulated from the first power signal line 110, and the second power signal line 140 away from the non-display area 200 is electrically connected to the multiple first power signal lines 110 arranged along the second direction Y through the via 150.

[0058] Among them, reference Figure 6 As shown, the display area 100 includes a plurality of second power signal lines 140. Figure 6The following examples illustrate the second power signal line 140 (141 in the figure) near the non-display area 200 and the second power signal line 140 (142 in the figure) away from the non-display area 200. Furthermore, the first power signal line 110 extends along the first direction X, i.e., from the display area 100 toward the non-display area 200. Because the first power signal line 110 has resistance, the power signal transmitted in the first power signal line 110 experiences greater loss in the first power signal line 110 as the distance from the non-display area 200 increases. Therefore, the intensity of the power signal transmitted in the first power signal line 110 is higher near the non-display area 200 than far from the non-display area 200. Therefore, in an embodiment of the present invention, the first power signal line 110 close to the non-display area 200 is not connected in parallel to the second power signal line 140 through the via 150, and the first power signal line 110 away from the non-display area 200 is connected in parallel to the second power signal line 140 through the via 150. By setting the second power signal line 140 in parallel with the first power signal line 110, the resistance on the power signal line away from the non-display area 200 is reduced, the transmission loss of the power signal in the first power signal line 110 is compensated, and the difference in power signals between the side close to the non-display area 200 and the side away from the non-display area 200 is neutralized, thereby ensuring the balance of the power signals in different areas of the display area 100, and thereby improving the display balance of the display panel.

[0059] Figure 7 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 7 As shown, among the multiple second power signal lines 140, there are two second power signal lines 140, the number of connecting vias 150 between the second power signal lines 140 close to the non-display area 200 and the multiple first power signal lines 110 arranged along the second direction Y is the third number, and the number of connecting vias 150 between the second power signal lines 140 away from the non-display area 200 and the multiple first power signal lines 110 arranged along the second direction Y is the fourth number, wherein the third number is less than the fourth number.

[0060] Among them, reference Figure 7 As shown, the display area 100 includes a plurality of second power signal lines 140. Figure 7The following examples illustrate the second power signal line 140 (143 in the figure) near the non-display area 200 and the second power signal line 140 (144 in the figure) away from the non-display area 200. Furthermore, the first signal line 110 extends along the first direction X, i.e., from the display area 100 toward the non-display area 200. Because the first power signal line 110 has resistance, the power loss generated in the first power signal line 110 increases as the distance from the non-display area 200 increases. Therefore, the intensity of the power signal transmitted in the first power signal line 110 is higher near the non-display area 200 than far from the non-display area 200. Therefore, in an embodiment of the present invention, the number of connecting vias 150 between the second power signal line 140 close to the non-display area 200 and the multiple first power signal lines 110 arranged along the second direction Y is smaller than the number of connecting vias 150 between the second power signal line 140 away from the non-display area 200 and the multiple first power signal lines 110 arranged along the second direction Y. That is, the second power signal line 140 away from the non-display area 200 is electrically connected to more first power signal lines 110 through the vias 150. This can reduce the resistance on the power signal line away from the non-display area 200, compensate for the difference in transmission loss of the power signal in different areas of the display area, and then neutralize the difference in power signal between the side close to the non-display area 200 and the side away from the non-display area 200, thereby ensuring the balance of the power signal in different areas of the display area 100 and improving the display balance of the display panel.

[0061] Specifically, refer to Figure 7 As shown, the second power signal line 140 ( Figure 7 143) is electrically connected to the plurality of first power signal lines 110 through a third number of vias 150. In the figure, three vias 150 are used as an example. The second power signal line 140 ( Figure 7 144) is electrically connected to the plurality of first power signal lines 110 through a fourth number of vias 150. Seven vias 150 are used as an example in the figure, and the embodiment of the present invention does not specifically limit the number of vias 150. By adjusting the number of vias 150, the loss of power signals transmitted away from the non-display area 200 can be further reduced, the display brightness differences in the display area 100 can be balanced, and the display effect of the display panel 10 can be further balanced.

[0062] Figure 8 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 8As shown, the first power signal line 110 located in the first display area 120 is electrically connected to p second power signal lines 140, where p is a positive integer; the first power signal line 110 located in the second display area 130 is electrically connected to q second power signal lines 140, where q is a positive integer; wherein p≤q.

[0063] Specifically, refer to Figure 8 As shown, there are p vias 150 on the first power signal line 110 in the first display area 120 for electrically connecting to the p second power signal lines 140, and there are q vias 150 on the first power signal line 110 in the second display area 130 for electrically connecting to the q second power signal lines 140. Where p≤q, that is, the number of vias 150 on the first power signal line 110 in the first display area 120 is less than or equal to the number of vias 150 on the first power signal line 110 in the second display area 130. Furthermore, the resistance on the power signal line in the display area 100 is reduced by connecting the second power signal line 140 in parallel with the first power signal line 110. Specifically, the degree of resistance reduction in the first display area 120 is less than the degree of resistance reduction in the second display area 130, that is, the power signal in the first power signal line 110 of the second display area 130 compensates for more transmission loss, neutralizes the power signal difference between the first display area 120 and the second display area 130, ensures the balance of the power signal in different areas of the display area 100, and thereby improves the display balance of the display panel 10.

[0064] Exemplary, reference Figure 8 As shown, in region E2, there is one via 150 at the first power signal line 110 located in the first display area 120 for realizing electrical connection with one second power signal line 140, and in region E1, there are three vias 150 at the first power signal line 110 located in the second display area 130 for realizing electrical connection with three second power signal lines 140. Among them, the area of ​​region E1 and region E2 is the same, that is, the difference in the number of vias in different display areas is reflected under the same area.

[0066] The display panel 10 further includes a plurality of sub-pixels 300, and the sub-pixels 300 are electrically connected to the first power signal line 110, enabling the sub-pixels 300 to display and emit light, thereby achieving the display function of the display panel 10. Specifically, the sub-pixels 300 include red sub-pixels, green sub-pixels, and blue sub-pixels, thereby achieving a color display effect of the display panel 10.

[0067] Among them, the sub-pixel minimum repeating unit 310 refers to a minimum repeating unit that periodically arranges multiple sub-pixels in a row or column form. Exemplarily, the sub-pixel minimum repeating unit 310 may include an "RGBG" arrangement, a "delta" arrangement, a "diamond" arrangement, etc., and the embodiment of the present invention does not specifically limit this. Further, the first display area 120 includes multiple sub-pixel minimum repeating units 310, refer to Figure 9 As shown, the same sub-pixel minimum repeating unit 310 includes n columns of sub-pixels 300. In the figure, n is taken as 4 for illustration. The embodiment of the present invention does not limit the specific value of n.

[0068] Furthermore, the first display area 120 includes a plurality of second power signal line groups 110D. The first power signal lines 110 in any two second power signal line groups 110D are connected to the first bus subsection 211 in the same manner, that is, the first power signal lines 110 and the first bus subsection 211 in the first display area 120 are regularly arranged. The same second power signal line group 110D includes m first power signal lines 110, and the second power signal line group 110D has a variety of arrangement forms, see reference. Figure 9As shown, m in the second power signal line group 110D1 can be 4, or m in the second power signal line group 110D2 can be 8. The embodiment of the present invention does not limit the specific value of m. It should be noted that in the first display area 120, the second power signal line group 110D is arranged in the form of the second power signal line group 110D1 or the second power signal line group 110D2, that is, in the first display area 120, the second power signal line group 110D is arranged in one form. Figure 9 In the figure, only one possible situation of the second power signal line group 110D is shown. Meanwhile, m=k*n, k is a positive integer, that is, the first power signal line 110 in the second power signal line group 110D is an integer multiple of the first power signal line 110 in the sub-pixel minimum repeating unit 310. Figure 9 When the second power signal line group 110D1 is used as the second power signal line group 110, k=1. Figure 9 When the second power signal line group 110D1 is used as the second power signal line group 110, k = 2. By setting an integer multiple, the luminous effect of each sub-pixel minimum repeating unit 310 in the display panel 10 is balanced, thereby balancing the display brightness of the display area 100 and further ensuring the uniformity of the display effect of the display panel 10.

[0069] Figure 10 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 11 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 10 and Figure 11As shown, the second bus division 212 includes a first sub-bus division 212A and a second sub-bus division 212B, the first sub-bus division 212A is located on the side of the first bus division 212 away from the center f of the display panel 10, and the second sub-bus division 212B is located on the side of the first bus division 212 close to the center f of the display panel 10; the non-display area 200 also includes a power connection line 240, the power connection line 240 includes a first power connection line 241 and a second power connection line 242, the first power connection line 241 is arranged in series between the two power lead lines 220, and the second power connection line 242 is arranged in series between the first power connection line 241 and the second sub-bus division 212B; the second display area 130 includes a first sub-display area 130A and a second Sub-display area 130B, the first sub-display area 130A is located on the side of the first display area 130A away from the center f of the display panel 10, and the second sub-display area 130B is located on the side of the first display area 130A close to the center f of the display panel 10; along the first direction X, the projection of the first sub-display area 130A on the power bus 210 has an overlapping area with the first sub-bus division 212A, and the projection of the second sub-display area 130B on the power bus 210 has an overlapping area with the second sub-bus division 212B; the first power signal lines 110 located in the first sub-display area 130A are all electrically connected to the second sub-bus division 212B, and the first power signal lines 110 located in the second sub-display area 130B are at least partially electrically connected to the first sub-bus division 212A.

[0070] Among them, reference Figure 10 and Figure 11 As shown, second bus segment 212 includes a first sub-bus segment 212A and a second sub-bus segment 212B, with first sub-bus segment 212A being further away from the center f of display panel 10 than second sub-bus segment 212B. Furthermore, non-display area 200 also includes power connection lines 240, wherein a first power connection line 241 is serially connected between two power lead lines 220, and a second power connection line 242 is serially connected between first power connection line 241 and second sub-bus segment 212B. In other words, the power signal transmitted by power bus 210 is specifically transmitted to second sub-bus segment 212B via first power connection line 241. In other words, second sub-bus segment 212B is closer to power lead lines 220 than first sub-bus segment 212A. Therefore, the power loss of the power signal transmitted when first power signal line 110 is electrically connected to second sub-bus segment 212B is less than the power loss of the power signal transmitted when first power signal line 110 is electrically connected to first sub-bus segment 212A.

[0071] Furthermore, the second display area 130 includes a first sub-display area 130A and a second sub-display area 130B. The first sub-display area 130A is farther away from the center f of the panel 10 than the second sub-display area 130B. At the power bus 210, the projection of the first sub-display area 130A overlaps with the first sub-bus segment 212A. Figure 10 and Figure 11 In the H area, the first power signal line 110 in the first sub-display area 130A transmits the power signal through the first sub-bus sub-section 212A in the H area, and the projection of the second sub-display area 130B overlaps with the second sub-bus sub-section 212B. Figure 10 and Figure 11 In the middle G region, the first power signal line 110 in the second sub-display area 130B transmits the power signal through the second sub-bus segment 212B in the G region. Furthermore, the second sub-bus segment 212B in the G region is closer to the power lead 220 than the first sub-bus segment 212A in the H region. Therefore, the second sub-bus segment 212B generates less power loss than the first sub-bus segment 212A. Due to the different relative positions between the multiple power buses 210 and the power lead 220, the power loss in the power signal received by the first power signal lines 110 at different locations varies, thereby affecting the display balance of the display panel 10.

[0072] Specifically, the first power signal line 110 located in the second sub-display area 130B is at least partially electrically connected to the second sub-bus segment 212B, that is, referring to FIG. Figure 10 As shown, there is a situation where part of the first power signal line 110 in the second sub-display area 130B is electrically connected to the second sub-bus sub-portion 212B, and part of the first power signal line 110 in the second sub-display area 130B is not connected to the second sub-bus sub-portion 212B, that is, it is insulated. Figure 11 As shown, all first power signal lines 110 in the second sub-display area 130B are electrically connected to the second sub-bus segment 212B, while all first power signal lines 110 in the first sub-display area 130A are electrically connected to the first sub-bus segment 212A. In other words, due to the difference in position between the first sub-bus segment 212A and the second sub-bus segment 212B and the power lead 220, the first sub-bus segment 212A is farther away from the power lead 220, resulting in greater power loss in the first power signal lines 110. By insulating the second sub-bus segment 212B from some first power signal lines 110, the power signal loss in these first power signal lines 110 can be reduced, thereby ensuring balanced power signal loss for the first power signal lines 110 at different locations in the display area 100, and thereby ensuring a balanced display for the entire display panel 10.

[0073] Continue to refer Figure 10 and Figure 11 As shown, all first power signal lines 110 in the second sub-display area 130B are electrically connected to the second sub-bus sub-portion 212B; or, part of the first power signal lines 110 in the second sub-display area 130B is electrically connected to the second sub-bus sub-portion 212B.

[0074] Among them, reference Figure 11 As shown, the first power signal lines 110 in the second sub-display area 130B are all electrically connected to the second sub-bus sub-portion 212B, that is, the first power signal lines 110 in the first sub-display area 130A and the first power signal lines 110 in the second sub-display area 130B are arranged in the same direction. Figure 10 As shown, part of the first power signal line 110 located in the second sub-display area 130B is electrically connected to the second sub-bus division 212B, that is, there is a first power signal line 110 insulated from the second sub-bus division 212B in the second sub-display area 130B, that is, the setting trend of the first power signal line 110 in the second sub-area display area 130B and the first power signal line 110 in the first display area 120 is the same. In other words, along the first direction X, the projection of the second sub-display area 130B on the power bus 210 is closer to the power lead 220 than the projection of the first sub-display area 130A on the power bus 210, and the projection of the first display area 120 on the power bus 210 is closer to the power lead 220 than the projection of the second sub-display area 130B on the power bus 210, that is, the second sub-display area 130B can be considered as an intermediate transition area, so the setting trend of the first power signal line 110 in the second sub-display area 130B and the first power signal line 110 in the first sub-display area 130A are the same, or the setting trend of the first power signal line 110 in the second sub-display area 130B and the first power signal line 110 in the first display area 120 can be the same, so as to achieve the overall display balance of the display panel 10, and the embodiment of the present invention does not make specific limitations on this.

[0075] Figure 12 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 12 As shown, the non-display area 200 includes a first non-display area 200A, a bending area 200B and a second non-display area 200C. The first non-display area 200A is located between the bending area 200B and the display area 100, and the second non-display area 200C is located on the side of the bending area 200B away from the display area 100; the power bus 210 is arranged in the first non-display area 200A, the first power connection line 241 is arranged in the second non-display area 200C, and the power lead line 220 and the second power connection line 242 extend from the second non-display area 200C along the bending area 200B to the first non-display area 200A.

[0076] The non-display area 200 includes a first non-display area 200A, a bending area 200B, and a second non-display area 200C. By setting the bending area 200B, some wiring can be set on the non-light-emitting side of the display panel 10, reducing the area occupied by the frame of the display panel 10 and achieving a larger display effect of the display panel 10. Figure 12 As shown, the wiring running in the first non-display area 200A and the second non-display area 200C can be electrically connected through the bending area 200B, thereby ensuring the transmission of signals in the display panel 10.

[0077] For further reference, Figure 12 As shown, the first non-display area 200A is close to the display area 100, so the power bus 210 is set in the first non-display area 200A to facilitate the electrical connection between the power bus 210 and the first power signal line 110. The first power connection line 241 is set in the second non-display area 200C, which reduces the space occupied by the power connection line 240 in the bending area 200B and facilitates the bending effect of the bending area 200B. In addition, the power lead line 220 and the second power connection line 242 extend from the second non-display area 200C along the bending area 200B to the first non-display area 200A, ensuring that the power signal is transmitted from the power signal terminal 230 to the first power signal line 110, ensuring signal transmission, and thus achieving the display effect of the display panel 10.
