[0034] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0035] Figure 1 A schematic diagram of a partial structure of a display panel provided by an embodiment of the present invention is shown. Figure 2 A partial structural diagram of a display panel provided by an embodiment of the present invention. Figure 1 and Figure 2 As shown, the display panel includes:

[0036] Multiple electrode structures 10 are arranged in an array; each electrode structure 10 includes an anode 101 and an anode line-changing hole 102, and the multiple electrode structures 10 include a first electrode structure 110 and a second electrode structure 120; the anode 111 in the first electrode structure 110 is connected to the anode line-changing hole 112 in the same electrode structure 10;

[0037] The electrode connection line 130, the anode 121 in the second electrode structure 120 is connected to the anode line change hole 122 in the other electrode structure 10 through the electrode connection line 130; the anode line change hole 112 in the first electrode structure 110 has a first edge L1, and the anode line change hole 122 in the second electrode structure 120 has a second edge L2, and the angle A between the extension direction X1 of the first edge L1 and the extension direction X2 of the adjacent edge of the adjacent anode 101 is greater than the angle A between the extension direction X3 of the second edge L2 and the extension direction X4 of the adjacent edge of the adjacent anode 101 ( Figure 1 and Figure 2 ); wherein, among all edges of the anode wire change hole 112 of the first electrode structure 110, the first edge L1 has the minimum distance from the geometric center of the anode wire change hole 112, and among all edges of the anode wire change hole 122 of the second electrode structure 120, the second edge L2 has the minimum distance from the geometric center of the anode wire change hole 122.

[0038] Specifically, when multiple electrode structures 10 are arranged in an array, the anodes 101 in the multiple electrode structures 10 are arranged in an array, and the anode line-changing holes 102 in the multiple electrode structures 10 are arranged in an array. In different electrode structures 10, the anode line-changing holes 102 are all located on the same side of the anode 101. For example, Figure 1 and Figure 2 As shown, each anode 101 has a center line M extending along the column direction Y of the electrode structures 10. At this time, along the row direction X of the electrode structures 10, the anode line change hole 102 in each electrode structure 10 is located to the left of the center line M of the anode 101.

[0039] The difference between the first electrode structure 110 and the second electrode structure 120 is that the anode 111 in the first electrode structure 110 is connected to the anode line hole 112 in the electrode structure 10. The anode 121 in the second electrode structure 120 is connected to the anode line hole 122 in another electrode structure 10 through the electrode connection line 130. For example, Figure 1 and Figure 2 As shown, the display panel may include pixel circuits and light emitting devices of different colors. The pixel circuits are connected to anodes of the light emitting devices of different colors to drive the light emitting devices of different colors to emit light. Figure 1 and Figure 2 exemplarily shows that the light emitting device includes a red light emitting device (indicated by a red wireframe), a green light emitting device (indicated by a green wireframe) and a blue light emitting device (indicated by a blue wireframe). Figure 2 In the partial structural diagram of the first row of green light emitting devices (i.e. Figure 2 The anode 101 in the green line frame of the first row in the figure and the anode line-changing hole 102 on the left side of the center line M form a set of electrode structures 10. Figure 2 The anode 101 in the green line frame of the first row in the figure is connected to the anode wire hole 102 in the electrode structure 10 of the same group, then the green light emitting device in the first row (ie Figure 2 The electrode structure 10 composed of the anode 101 in the first row (the green frame) and the anode wire hole 102 on the upper left side of the center line M is the first electrode structure 110. The blue light emitting device in the second row (i.e. Figure 2 The anode 101 in the blue frame of the second row and the anode wire-changing hole 102 on the lower left side of the center line M form a set of electrode structures 10. The red light-emitting device in the second row (i.e. Figure 2 The anode 101 in the red frame of the second row and the anode wire-changing hole 102 on the lower left side of the center line M form a set of electrode structures 10. Figure 2 The anode 101 in the second row of the blue frame (the second row of the blue frame) is connected to the anode wire hole 102 in another set of electrode structures 10 through the electrode connection line 130. That is, the blue light emitting device in the second row (ie Figure 2 The anode 101 in the second row of the blue wire frame) corresponds to the anode wire hole 102 connected to the red light emitting device in the second row (ie Figure 2 The anode 101 in the red line frame of the second row is a set of electrode structures 10, which are connected to the blue light emitting devices in the second row (i.e. Figure 2 The anode 101 in the second row of blue light emitting devices (ie, the anode 101 in the second row of blue light emitting devices) is a different group of electrode structures 10. Figure 2The electrode structure 10 composed of the anode 101 in the blue wire frame of the second row in the middle and the anode wire hole 102 on the lower left side of the center line M is the second electrode structure 120. The red light emitting device in the second row (ie Figure 2 The electrode structure 10 composed of the anode 101 in the red wire frame in the second row (in the middle) and the anode wire-changing hole 102 on the lower left side of the center line M is the second electrode structure 120.

[0040] The adjacent anode 101 of the anode line changing hole 102 may be the anode around the anode line changing hole 102. Figure 2 , and the green light emitting devices in the first row (i.e. Figure 2 The anode 101 connected to the anode line hole 102 adjacent to the anode 101 in the first row of the green frame) may include a red light emitting device in the previous row (ie Figure 2 The anode 101 in the red line frame shown on the upper side of the first row of green line frames and the blue light emitting device in the previous row (ie Figure 2 The anode 101 in the blue line frame shown on the upper part of the green line frame in the first row. Figure 2 The lower right edge of the anode 101 in the red line frame shown on the upper part of the green line frame in the first row is the adjacent edge of the anode 101 adjacent to the first edge L1. Figure 2 The lower left edge of the anode 101 in the blue line frame shown on the upper part of the first row of green line frames is the adjacent edge of the anode 101 adjacent to the first edge L1. Figure 2 The anode 101 connected to the anode line hole 102 adjacent to the anode 101 in the second row of the blue wire frame) may include the red light emitting device in the second row (ie Figure 2 The anode 101 in the second row of red lines and the green light emitting device in the third row (ie Figure 2 The anode 101 in the third row of the green frame) is now Figure 2 The lower left edge of the anode 101 in the red line frame of the second row is the adjacent edge of the anode 101 adjacent to the second edge L2, and the green light emitting device in the third row (ie Figure 2 The upper right edge of the anode 101 in the green line frame in the third row (in FIG. 1 ) is the adjacent edge of the anode 101 adjacent to the second edge L2.

[0041] The anode line change hole 102 may include multiple edges, and the distances from different edges to the geometric center of the anode line change hole 102 may be the same or different. Figure 1 and Figure 2The anode reconnection hole 102 is exemplarily shown as a square with chamfered corners. In this case, the distances from the geometric center of the anode reconnection hole 102 to the edges are the same. The first edge L1 and the second edge L2 can be any edges of the anode reconnection hole 102.

[0042] In other embodiments, the shape of the anode line change hole 102 can also be a rectangle with a certain chamfer angle at the top corner. Figure 3 This is a schematic diagram of the structure of an anode shape provided by an embodiment of the present invention. Figure 3 As shown, different edges have different distances from the geometric center of the anode cable reversal hole 102. In this case, the first edge L1 and the second edge L2 can be the longer sides of the anode cable reversal hole 102. The distance from the first edge L1 to the geometric center of the anode cable reversal hole 112 in the first electrode structure 110 is the smallest relative to the other edges. Similarly, the distance from the second edge L2 to the geometric center of the anode cable reversal hole 122 in the second electrode structure 120 is the smallest relative to the other edges of the anode cable reversal hole 122 in the second electrode structure 120. Different anode cable reversal holes 102 have the same shape. Therefore, the distance from the first edge L1 to the geometric center of the anode cable reversal hole 112 in the first electrode structure 110 is equal to the distance from the second edge L2 to the geometric center of the anode cable reversal hole 122 in the second electrode structure 120.

[0043] The angle A between the extension direction X1 of the first edge L1 and the extension direction X2 of the edge of the adjacent anode 101 is the angle formed by the first edge L1 and the edge of the adjacent anode 101 after they are extended. The angle between the extension direction X3 of the second edge L2 and the extension direction X4 of the edge of the adjacent anode 101 is the angle formed by the second edge L2 and the edge of the adjacent anode 101 after they are extended. For example, Figure 1 and Figure 2In the embodiment, the extension direction X3 of the second edge L2 is the same as the extension direction X4 of the edge of the adjacent anode 101, such that the angle between the extension direction X3 of the second edge L2 and the extension direction X4 of the edge of the adjacent anode 101 is zero. By setting the angle A between the extension direction X1 of the first edge L1 and the extension direction X2 of the edge of the adjacent anode 101 to be greater than the angle between the extension direction X3 of the second edge L2 and the extension direction X4 of the edge of the adjacent anode 101, the length occupied by the anode line change hole 112 in the first electrode structure 110 in the first direction is greater than the length occupied by the anode line change hole 122 in the second electrode structure 120 in the second direction. Compared to the length occupied by the anode line change hole 112 between adjacent anodes 101 in the first electrode structure 110, the length occupied by the anode line change hole 122 in the second electrode structure 120 between adjacent anodes 101 is smaller. The first direction is the direction perpendicular to the direction in which the adjacent edges of the first edge L1 extend from adjacent anodes 101. The second direction is the direction perpendicular to the direction in which the adjacent edges of the second edge L2 extend from adjacent anodes 101. When the spacing between different anodes 101 is equal, the distance between the anode line-changing hole 122 in the second electrode structure 120 and the adjacent anode 101 can be increased to avoid short circuit between the anode 121 in the second electrode structure 120 and the adjacent anode 101, thereby ensuring the reliability of the display panel. Therefore, by setting the angle A between the extension direction X1 of the first edge L1 and the edge extension direction X2 of the adjacent anode 101 to be greater than the angle between the extension direction X3 of the second edge L2 and the edge extension direction X4 of the adjacent anode 101, the spacing difference between different anodes 101 can be reduced, the density consistency of the anode 101 is improved, and the mura phenomenon of the display panel is improved. At the same time, it can avoid additional occupation of the opening area space of the display panel, thereby ensuring the pixel density of the display panel. For example, refer to Figure 2 , and the green light emitting devices in the first row (i.e. Figure 2 The anode 101 connected to the anode line hole 102 in the first row of the green light emitting devices (ie Figure 2 The green wireframe in the first row) and the red light-emitting devices in the previous row (i.e. Figure 2 The vertical distance d1 between the red line frame shown on the upper part of the green line frame in the first row is greater than the vertical distance d1 between the blue light emitting devices in the second row (ie Figure 2 The anode 101 connected to the anode change hole 102 in the second row of the blue frame) occupies the second row of red light emitting devices (ie Figure 2 The red line frame in the second row) and the green light emitting device in the third row (i.e. Figure 2 The vertical distance d2 between the green light emitting devices in the first row (i.e. Figure 2 The anode 101 in the first row (the green line frame) and the red light emitting device in the previous row (ie Figure 2The distance d3 between the anode 101 in the red line frame shown on the upper part of the green line frame in the first row and the blue light emitting device in the second row (ie Figure 2 The anode 101 in the second row of blue wireframes) and the green light emitting device in the third row (ie Figure 2 When the distance d4 between the anodes 101 in the third row of the green frame is equal, the distance d4 between the anodes 101 and the blue light emitting devices in the second row (ie Figure 2 The anode 101 in the blue wire frame of the second row is connected to the anode line hole 102 of the red light emitting device in the second row (ie Figure 2 The distance to the anode 101 in the second row of red lines and the distance to the green light emitting device in the third row (ie Figure 2 The sum of the distances to the anode 101 in the third row of the green line frame is greater than the sum of the distances to the green light emitting devices in the first row (i.e. Figure 2 The anode 101 in the green line frame of the first row) is connected to the anode line hole 102 to the red light emitting device in the previous row (ie Figure 2 The distance between the anode 101 and the anode 101 in the red frame (shown in the upper portion of the first row of green frames in FIG). This ensures that the anode line-changing holes 122 in the second electrode structure 120 are spaced apart from the adjacent anodes 121, thereby preventing short circuits between the anodes 121 in the second electrode structure 120 and the adjacent anodes 101, thereby improving the reliability of the display panel and avoiding additional occupation of the opening area of ​​the display panel, thereby ensuring the pixel density of the display panel.

[0044] In some embodiments, the anode line-changing holes 122 in the second electrode structure 120 can be rotated relative to the anode line-changing holes 112 in the first electrode structure 110, so that the angle A between the extension direction X1 of the first edge L1 and the extension direction X2 of the adjacent edge of the adjacent anode 101 is greater than the angle between the extension direction X3 of the second edge L2 and the extension direction X4 of the adjacent edge of the adjacent anode 101. When the spacing between adjacent anodes 101 is the same, the spacing between the anode line-changing holes 122 in the second electrode structure 120 and the adjacent anode 101 can be increased. While ensuring the consistency of the density of the anodes 101, the anode line-changing holes 122 in the second electrode structure 120 are spaced apart from the adjacent anodes 121, thereby preventing short circuits between the anodes 121 in the second electrode structure 120 and the adjacent anodes 101, ensuring the reliability of the display panel, and avoiding additional space occupied in the opening area of ​​the display panel, thereby ensuring the pixel density of the display panel.

[0045] The technical solution of this embodiment can reduce the spacing between adjacent anodes occupied by the anode line-changing holes in the second electrode structure by setting the angle between the extension direction of the first edge and the extension direction of the adjacent edge of the adjacent anode to be greater than the angle between the extension direction of the second edge and the extension direction of the adjacent edge of the adjacent anode. When the spacing between different anodes is equal, the distance between the anode line-changing holes in the second electrode structure and the adjacent anodes can be increased, thereby avoiding short circuits between the anodes in the second electrode structure and the adjacent anodes on the basis of ensuring the consistency of the anode density, thereby improving the reliability of the display panel and avoiding additional occupation of the opening area space of the display panel, thereby ensuring the pixel density of the display panel.

[0046] Continue to refer Figure 1 and Figure 2 The included angle between the extension direction X3 of the second edge L2 and the extension direction X4 of the adjacent edge of the adjacent anode 101 is 0.

[0047] Specifically, the angle between the extension direction X3 of the second edge L2 and the extension direction X4 of the adjacent edge of the adjacent anode 101 is 0, that is, the second edge L2 is parallel to the adjacent edge of the adjacent anode 101. In this case, the length of the anode line change hole 122 in the second electrode structure 120 between adjacent anodes 101 along the second direction is half the length of the second edge L2. The angle between the extension direction X1 of the first edge L1 and the extension direction X2 of the adjacent edge of the adjacent anode 101 can be 45°. In this case, the length of the anode line change hole 112 in the first electrode structure 110 between adjacent anodes 101 along the first direction is greater than half the length of the first edge L1. The lengths of the first edge L1 and the second edge L2 are equal, so that the length of the anode line change hole 122 in the second electrode structure 120 between adjacent anodes 101 along the second direction is less than the length of the anode line change hole 112 in the first electrode structure 110 between adjacent anodes 101 along the first direction. When the spacing between different anodes 101 is equal, the spacing between the anode line-changing hole 122 in the second electrode structure 120 and the adjacent anode 101 can be increased, ensuring that the anode line-changing hole 122 in the second electrode structure 120 and the adjacent anode 121 are spaced apart, avoiding short circuit between the anode 121 in the second electrode structure 120 and the adjacent anode 101, thereby improving the reliability of the display panel and avoiding additional occupation of the opening area space of the display panel, thereby ensuring the pixel density of the display panel.

[0048] Continue to refer Figure 1The multiple electrode structures 10 include a first column electrode structure 10A and a second column electrode structure 10B alternately arranged along the row direction X. The first column electrode structure 10A includes a first anode R and a second anode B alternately arranged along the column direction Y. In two adjacent columns of the first column electrode structures 10A, the anodes in the same row are the first anode R and the second anode B respectively; the second column electrode structure 10B includes a third anode G; in the first column electrode structure 10A, the electrode structures 10 in odd rows are the first electrode structures 110, and the electrode structures 10 in even rows are the second electrode structures 120.

[0049] Specifically, such as Figure 1 As shown, the display panel includes a plurality of columns of electrode structures 10, along the row direction X of the electrode structures 10, the first anodes R and the second anodes B are arranged alternately, and along the column direction Y of the electrode structures 10, the first anodes R and the second anodes B are arranged alternately. When the light-emitting device corresponding to the first anode R, the light-emitting device corresponding to the second anode B, and the light-emitting device corresponding to the third anode G form a pixel unit, the light-emitting device corresponding to the first anode R and the light-emitting device corresponding to the second anode B are shared by different pixel units. For example, in Figure 1 In the example, the first anode R is a red light emitting device ( Figure 1 The anode of the red wire frame) and the second anode B are blue light emitting devices ( Figure 1 The anode of the blue wire frame) and the third anode G are green light emitting devices ( Figure 1 anode (green wireframe in the middle).

[0050] When the first anodes R and the second anodes B in the first column electrode structure 10A are arranged alternately, the electrode structures 10 in odd rows can be set as the first electrode structure 110, and the electrode structures 10 in even rows can be set as the second electrode structure 120. That is, in the first column electrode structure 10A, the first anodes R in the electrode structures 10 in odd rows are connected to the anode line-changing holes 102 in the same electrode structure 10, and the second anodes B in the electrode structures 10 in odd rows are connected to the anode line-changing holes 102 in the same electrode structure 10, so that the anodes 101 in the mth row and nth column are connected to the anode line-changing holes 102 in the mth row and nth column. Wherein, m is an odd number, and n is the column number where the first column electrode structure 10A is located. For example, as Figure 1As shown, the first column of electrode structures 10A is an odd column, so n is an odd number. Simultaneously, in the first column of electrode structures 10A, the first anodes R in the even-numbered rows of electrode structures 10 are connected to the anode reversal holes 102 in another electrode structure 10, and the second anodes B in the even-numbered rows of electrode structures 10 are connected to the anode reversal holes 102 in another electrode structure 10. Exemplarily, in the first column of electrode structures 10A, the anodes 121 in the second electrode structures 120 are connected to the anode reversal holes 102 in the same row of the next first column of electrode structures 10A via electrode connection lines 130, such that the anodes 101 in the p-th row, q-th column are connected to the anode reversal holes 102 in the p-th row, q+2-th column. Exemplarily, the first column of electrode structures 10A are sequentially arranged in odd columns, and the second column of electrode structures 10B are sequentially arranged in even columns. When q is 1, the anodes 101 in the even-numbered rows of the first column are connected to the anode reversal holes 102 in the same row of the third column.

[0051] When the anode line switching holes 101 in the same column are connected to the same data signal line D, the anodes 102 corresponding to the same data signal line D can be anodes of light-emitting devices of the same color, which can reduce the voltage jump frequency provided by the driver chip of the display panel, thereby reducing the driving power consumption of the driver chip and reducing the power consumption of the entire device. For example, when each column of anode line switching holes 101 corresponds to a data signal line D, along the row direction X of the electrode structure 10, the first data signal line D1 can be used to drive the light-emitting device corresponding to the first anode R, the second data signal line D2 can be used to drive the light-emitting device corresponding to the third anode G, and the third data signal line D3 can be used to drive the light-emitting device corresponding to the second anode B, so that the anodes 102 corresponding to the same data signal line D can be anodes of light-emitting devices of the same color, reducing the voltage jump frequency provided by the driver chip of the display panel, thereby reducing the driving power consumption of the driver chip and further reducing the power consumption of the entire device.

[0052] Continue to refer Figure 1 , different electrode connection lines 130 have the same shape, which can improve the density consistency of the electrode connection lines 130, thereby improving the signal consistency on different anodes 101, improving the mura phenomenon of the display panel, and reducing the risk of off-screen mura when the display panel is in a dark state. For example, Figure 1 and Figure 2 As shown, the electrode connection lines 130 are all in the shape of broken lines.

[0053] Continue to refer Figure 1The electrode structure 10 in the second column electrode structure 10B is the first electrode structure 110. Without adding an additional electrode connection line 130, the third anode G in the second column electrode structure 10B can be connected to the same data signal line D, so that the anodes 102 corresponding to the same data signal line D are anodes of light-emitting devices of the same color, thereby reducing the voltage jump frequency provided by the driver chip of the display panel, thereby reducing the driving power consumption of the driver chip, and further reducing the power consumption of the entire device.

[0054] Figure 4 A schematic diagram of the principle structure of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, the display panel also includes:

[0055] A plurality of pixel circuits 20 are arranged in an array; the pixel circuit 20 in the i-th row and j-th column is connected to the anode line switching hole 102 in the i-th row and j-th column.

[0056] Specifically, the pixel circuit 20 is connected to the anode 101 through the anode line exchange hole 102, so that the pixel circuit 20 can provide a driving signal for the light-emitting device corresponding to the anode 101, driving the light-emitting device corresponding to the anode 101 to emit light. In the first column electrode structure 10A, the electrode structure 10 of the odd rows is the first electrode structure 110, the electrode structure 10 of the even rows is the second electrode structure 120, and when the electrode structure 10 in the second column electrode structure 10B is the first electrode structure 110, the anode 102 connected to the same data signal line D can be the anode of the light-emitting device of the same color. For example, Figure 4 As shown, the first data signal line D1 is connected to the first anode R in the first column of the electrode structure 10, the second data signal line D2 is connected to the third anode G in the second column of the electrode structure 10, and the third data signal line D3 is connected to the second anode B in the first column of the electrode structure 10 and the second anode B in the third column of the electrode structure 10. The same applies to the subsequent data signal lines. Figure 5 Schematic diagram of the cross-sectional structure of a display panel provided by an embodiment of the present invention. Figure 5As shown, the display panel includes a substrate 210 and a driving circuit layer 220 disposed on the substrate 210, and the driving circuit layer 220 is used to form a pixel circuit 20. The pixel circuit 20 can be composed of a transistor and a capacitor. The transistor can be a low-temperature polysilicon (LTPS) transistor, in which case the material of the semiconductor layer is PSI. In other embodiments, the transistor can also be a low-temperature polycrystalline oxide (LTPO) transistor, which is not limited here. The display panel also includes a driving signal line layer 230, which is disposed on a side of the driving circuit layer 220 away from the substrate 210, and is used to form a driving signal line to provide a driving signal to the pixel circuit 20. Exemplarily, the driving signal line layer 230 includes a data signal line D, which is connected to the pixel circuit 20 and is used to provide a data signal to the pixel circuit 20. The display panel also includes an electrode layer 240, which is disposed on a side of the driving signal line layer 230 away from the substrate 210 and is used to form an electrode structure 10.

[0057] When the pixel circuit 20 in the i-th row and j-th column is connected to the anode line switching hole 102 in the i-th row and j-th column, the cross-layer connection between the pixel circuit 20 and the anode line switching hole 102 can be achieved according to the principle of proximity, which simplifies the connection wiring between the pixel circuit 20 and the anode line switching hole 102, and further simplifies the layout and production difficulty of the display panel.

[0058] In some embodiments, continue to refer to Figure 1 and Figure 4 The display panel also includes multiple data signal lines D, each data signal line D is connected to a column of pixel circuits 20, which can also simplify the cross-layer connection between the data signal lines D and the pixel circuits 20, simplify the connection wiring between the pixel circuits 20 and the data signal lines D, and thus simplify the layout and manufacturing difficulty of the display panel.

[0059] In some embodiments, the electrode structure 10 and the electrode connection line 130 are disposed in the same layer.

[0060] Specifically, such as Figure 5 As shown, the display panel may include an electrode layer 240, and the electrode structure 10 and the electrode connecting line 130 may both be arranged in the electrode layer 240, which can fully utilize the space of the electrode layer 240 and at the same time avoid the electrode connecting line 130 occupying the space of the driving circuit layer 220 and the driving signal line layer 230, which is conducive to simplifying the layout and manufacturing difficulty of the display panel.

[0061] Continue to refer Figure 1 , the display panel also includes:

[0062] The dummy electrode structure 140 is connected to the anode 111 in the first electrode structure 110 .

[0063] Specifically, the anode 111 in the first electrode structure 110 is directly connected to the anode line change hole 112 in the same electrode structure 10, and the connection distance between the anode 111 and the anode line change hole 112 is relatively small. The anode 121 in the second electrode structure 120 can be connected to the anode line change hole 122 in another electrode structure 10 via an electrode connection wire 130. In this case, the electrode connection wire 130 is added between the anode 121 in the second electrode structure 110 and the anode line change hole 122 in the other electrode structure 10, compared to the connection between the anode 111 in the first electrode structure 110 and the anode line change hole 112 in the same electrode structure 10. By setting up a virtual electrode structure 140 to be connected to the anode 111 in the first electrode structure 110, the virtual electrode structure 140 can be equivalent to at least a portion of the electrode connection line 130, thereby reducing the difference between when the anode 111 in the first electrode structure 110 is connected to the anode line change hole 112 in the same electrode structure 10 and when the anode 121 in the second electrode structure 120 is connected to the anode line change hole 122 in another electrode 10, reducing the coupling difference between the anode 111 in the first electrode structure 110 and the anode 121 in the second electrode structure 120 and the adjacent anode 101, further improving the brightness uniformity of the display panel and improving the mura phenomenon of the display panel.

[0064] In some embodiments, the virtual electrode structure 140 and the electrode connection line 130 are disposed in the same layer, which can improve the density consistency of the electrode connection line 130, further reduce the coupling difference between different anodes 101, and improve the mura phenomenon of the display panel.

[0065] In some embodiments, the dummy electrode structure 140 and the electrode connection line 130 can be disposed in the same layer as the electrode structure 10 , and both are disposed in the electrode layer, thereby further improving the consistency of the electrode layer pattern density and further improving the mura phenomenon of the display panel.

[0066] Continue to refer Figure 1 The shape of the dummy electrode structure 140 is similar to the shape of the electrode connection line 130, which can further improve the density consistency of the electrode connection line 130, further reduce the coupling difference between different anodes 101, and improve the mura phenomenon of the display panel. For example, when the spacing between the anodes 101 in the odd-numbered rows of the first column electrode structure 10A of two adjacent columns is greater than the space required for the electrode connection line 130, the shape of the dummy electrode structure 140 can be set to be the same as the shape of the electrode connection line 130, thereby maximizing the density consistency of the electrode connection line 130, further reducing the coupling difference between different anodes 101, and improving the mura phenomenon of the display panel.

[0067] Continue to refer Figure 1 Along the row direction X in which the electrode structures 10 are arranged, the dummy electrode structure 140 is disposed on one side of the anode 111 in the first electrode structure 110 .

[0068] Specifically, when the dummy electrode structure 140 is connected to the anode 111 in the first electrode structure 110, the dummy electrode structure 140 can be disposed on the right side of the anode 111. The dummy electrode structure 140 and the anode line change hole 102 are located on either side of the anode 111 in the same first electrode structure 110, that is, the anode line change hole 102 is located on the left side of the anode 111 in the same first electrode structure 110. In this case, in two adjacent columns of first-column electrode structures 10A, the anodes 111 of the odd-numbered rows of the first electrode structures 110 in one column of the first-column electrode structures 10A can extend through the dummy electrode structure 140 to the anodes 111 of the first electrode structures 110 in the next row in the second-column electrode structure 10B in the next column. The anodes 121 in the second electrode structures 120 in the even rows of the first column electrode structure 10A of another column can be extended to the anodes 111 in the first electrode structure 110 in the next row of the second column electrode structure 10B of the next column through the electrode connection line 130, so that the virtual electrode structure 140 or the electrode connection line 130 can be extended to the anodes 111 in any row of the second column electrode structure 10B, thereby improving the coupling balance of the anodes 111 in the odd rows and even rows of the second column electrode structure 10B, thereby further improving the brightness uniformity of the display panel and improving the mura phenomenon of the display panel. For example, Figure 1 As shown, the electrode structure 10 in the first column and the electrode structure 10 in the third column are the first column electrode structures 10A of two adjacent columns, and the electrode structure 10 in the second column is the second column electrode structure 10B. A virtual electrode structure 140 is set to the right side of the first anode R11 in the first row of the electrode structure 10 in the first column, and the virtual electrode structure 140 extends to the third anode G21 in the first row of the electrode structure 10 in the second column. At the same time, the first anode R52 in the second row of the electrode structure 10 in the third column is extended to the third anode G42 in the second row of the electrode structure 10 in the fourth column through the electrode connection line 130. In this way, the virtual electrode structure 140 or the electrode connection line 130 can be extended to the anode 111 in any row of the second column electrode structure 10B, thereby improving the coupling balance of the anodes 111 in the odd and even rows of the second column electrode structure 10B, thereby further improving the brightness uniformity of the display panel and improving the mura phenomenon of the display panel.

[0069] Figure 6 A partial structural diagram of another display panel provided by an embodiment of the present invention. Figure 6As shown, the dummy electrode structure 140 can also be disposed on the left side of the correspondingly connected anode 111. The dummy electrode structure 140 and the anode line change hole 102 are located on the same side of the anode 111 in the same first electrode structure 110, that is, the dummy electrode structure 140 and the anode line change hole 102 are both located on the left side of the correspondingly connected anode 111. In this case, in two adjacent columns of first-column electrode structures 10A, the anodes 111 in the odd-numbered rows of the first-column electrode structures 10A in one column can be extended via the dummy electrode structure 140 to the anodes 111 in the odd-numbered rows of the first-column electrode structures 110 in the previous column of the second-column electrode structures 10B. The anodes 121 in the even-numbered rows of the second-column electrode structures 120 in the other column of the first-column electrode structures 10A can be extended via the electrode connection lines 130 to the anodes 111 in the even-numbered rows of the first-column electrode structures 110 in the next column of the second-column electrode structures 10B. Thus, the virtual electrode structure 140 or the electrode connection line 130 can be extended to the anode 111 of any row in the second column electrode structure 10B, thereby improving the coupling balance between the anodes 111 of odd and even rows in the second column electrode structure 10B, thereby further improving the brightness uniformity of the display panel and improving the mura phenomenon of the display panel. Figure 6 As shown, the electrode structure 10 in the first column and the electrode structure 10 in the third column are the first column electrode structures 10A of two adjacent columns, and the electrode structure 10 in the second column is the second column electrode structure 10B. A virtual electrode structure 140 is provided on the left side of the second anode B31 in the first row of the electrode structure 10 in the third column, and the virtual electrode structure 140 extends to the third anode G21 in the first row of the electrode structure 10 in the second column. At the same time, the second anode B32 in the second row of the electrode structure 10 in the first column is extended to the third anode G22 in the second row of the electrode structure 10 in the second column through the electrode connection line 130, so that the virtual electrode structure 140 or the electrode connection line 130 can be appropriately extended to the anode 111 in any row of the electrode structure 10B in the second column, thereby improving the coupling balance of the anodes 111 in the odd and even rows of the electrode structure 10B in the second column, thereby further improving the brightness uniformity of the display panel and improving the mura phenomenon of the display panel.

[0070] Continue to refer Figure 6 When the virtual electrode structure 140 and the anode line change hole 102 are located on the same side of the anode 111 in the same first electrode structure 110 , the virtual electrode structure 140 is connected to the anode 111 in the same first electrode structure 110 through the anode line change hole 102 .

[0071] Specifically, such as Figure 6As shown, in the same first electrode structure 110, the virtual electrode structure 140 is arranged on the side of the anode line change hole 102 away from the anode 111, which can prevent the virtual electrode structure 140 from affecting the position of the anode line change hole 102, ensure the regularity of the arrangement of different anode line change holes 102, and help to simplify the layout and manufacturing process of the display panel.
