Technical Field
[0001] The present application relates to the field of display technology, and in particular to a display panel, a display screen and a display device. Background Art
[0002] With the continuous development of display technology, the refresh rate of display panels is also increasing. At a high refresh rate, the row scanning time of the pixel circuit in the display panel is shortened, and the threshold compensation time of the pixel circuit is also shortened accordingly.
[0003] In the existing design, in order to increase the threshold compensation time of the pixel circuit, a dual data line driving method can be adopted, that is, the pixel circuits of adjacent rows in the same pixel column are connected to different data lines respectively. However, under this setting method, there is a problem of crosstalk between the data line and other signal lines in the display panel. Summary of the invention
[0004] The embodiments of the present application provide a display panel, a display screen and a display device, which can reduce the mutual crosstalk between data lines and other signal lines in the display panel, thereby improving the display performance.
[0005] In a first aspect, an embodiment of the present application provides a display panel, comprising a plurality of pixel circuit columns, a plurality of first data lines and a plurality of second data lines, wherein the pixel circuit columns are provided with one first data line and one second data line; wherein:
[0006] The pixel circuit column includes a plurality of first pixel circuits and a plurality of second pixel circuits. In the same pixel circuit column, each of the first pixel circuits is connected to the first data line, each of the second pixel circuits is connected to the second data line, and the layout structures of the first pixel circuits and the second pixel circuits are mirror images of each other along the direction of the pixel circuit column.
[0007] A first connection point between the first pixel circuit and the first data line is located at an edge of the first pixel circuit close to the first data line, and a second connection point between the second pixel circuit and the second data line is located at an edge of the second pixel circuit close to the second data line.
[0008] In a second aspect, an embodiment of the present application provides a display screen, comprising a cover plate and a display panel as described above, wherein the cover plate is located on a surface of the display panel in a light emitting direction.
[0009] In a third aspect, an embodiment of the present application provides a display device, which includes the display panel as described above.
[0010] In the display panel, display screen and display device provided by the embodiments of the present application, each pixel circuit column is respectively provided with a first data line and a second data line. In each pixel circuit column, each first pixel circuit is respectively connected to the first data line, and each second pixel circuit is connected to the second data line, and the layout structure of the first pixel circuit and the layout structure of the second pixel circuit are mirror images of each other along the direction of the pixel circuit column. In this case, the first connection point between the first pixel circuit and the first data line can be located at the edge of the first pixel circuit close to the first data line, and the second connection point between the second pixel circuit and the second data line can be located at the edge of the second pixel circuit close to the second data line. Therefore, when the first data line and the second data line are used to drive the same pixel circuit column, that is, when the dual data line (including the first data line and the second data line) driving mode is used, the data line does not need to cross the pixel circuit area to connect to the pixel circuit, that is, there is no need for a cross-line connection between the data line and the pixel circuit, which shortens the connection length between the data line and the pixel circuit, saves space, is conducive to realizing a display panel with a narrow frame and a high pixel density, and reduces the coupling capacitance between the data line and other signal lines in the display panel, thereby improving the problem of mutual crosstalk between the data line and other signal lines, and improving the display effect of the display panel. In addition, in the same pixel circuit column, the layout structure of the first pixel circuit and the second pixel circuit is designed as a mirror structure, which avoids the data line crossing in the pixel circuit area, reduces the total capacitance of the data line, and improves the pixel charging rate, so that the impedance of the display panel fan-out routing can be further increased and the line width can be further compressed, which is beneficial to the narrow bezel design of the display panel.

DETAILED DESCRIPTION
[0034] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0036] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or there may be intervening elements. Further, when a layer is referred to as being "under" another layer, it can be directly under or there may be one or more intervening elements. It is also understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there may be one or more intervening elements.
[0037] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.
[0038] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present application, a first data line may be referred to as a second data line, and similarly, a second data line may be referred to as a first data line.
[0039] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.
[0040] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.
[0041] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.
[0042] Figure 1 A schematic diagram of a top view of a display panel provided in an embodiment of the present application. Figure 1 In one embodiment, the display panel includes pixel circuits arranged in an array, each pixel circuit column 10 is connected to two data lines 20, and each pixel circuit column 10 writes data signals through the two connected data lines 20, that is, a double data line (DDL) driving method is adopted. In this way, the jump effect caused by the switch of each row of pixel circuits on the same data line 20 can be reduced, and the circuit stability can be improved. At the same time, the delay of the data line 20 signal can be reduced, and the charging efficiency of the pixel circuit can be improved, which is conducive to achieving high-frequency display.
[0043] As described in the background technology section, the display panel in the related art adopts a dual data line driving method, and there is a problem of mutual crosstalk between the data line and other signal lines in the display panel. The inventor found that the reason for the above problem is that since the layout structure of each pixel circuit in the display panel adopts a specific design, the connection points between each pixel circuit of the same pixel circuit column and the two data lines are located on the same side of the pixel circuit. Therefore, for the two data lines located on both sides of the pixel circuit column, at least one of the data lines needs to cross the pixel circuit area to connect with the pixel circuit, that is, the data line and the pixel circuit need to be connected across the line. Therefore, the data line with the cross-line connection is easily coupled by other signal lines in the display panel. Therefore, the data line and other signal lines are prone to mutual crosstalk, thereby affecting the display performance of the display panel. For example, Figure 2 A schematic diagram of a top view structure of a display panel is provided, such as Figure 2 As shown, due to the layout structure of the pixel circuit P, in each pixel circuit P column, the connection points CON between each pixel circuit P and the two data lines DL are all located on the left side of the pixel circuit P. Therefore, the data line DL located on the right side of the pixel circuit P column and the corresponding pixel circuit P need to be connected across the line in the row direction of the pixel circuit P. Therefore, the data line DL located on the right side of the pixel circuit P column is prone to crosstalk with the signal line extending along the row direction of the pixel circuit P in the display panel, thereby affecting the display performance of the display panel.
[0044] Based on the above technical problems, the inventors have found that by designing the pixel circuit layout structure connecting different data lines in the same pixel circuit column as a mirror structure along the direction of the pixel circuit column, the connection point between the data line and the pixel circuit is located at the edge of the pixel circuit close to the data line, which can avoid the cross-line connection between the data line and the pixel circuit, thereby reducing the mutual crosstalk between the data line and other signal lines in the display panel, thereby improving the display performance of the display panel. Based on this, the inventors further studied the technical solution of the embodiment of the present application. Specifically, the display panel provided by the embodiment of the present application includes multiple pixel circuit columns, multiple first data lines and multiple second data lines, and the pixel circuit column is provided with a first data line and a second data line; wherein, the pixel circuit column includes multiple first pixel circuits and multiple second pixel circuits, and in the same pixel circuit column, each first pixel circuit is respectively connected to the first data line, and each second pixel circuit is connected to the second data line, and the layout structure of the first pixel circuit and the second pixel circuit is a mirror structure of each other along the direction of the pixel circuit column; the first connection point between the first pixel circuit and the first data line is located at the edge of the first pixel circuit close to the first data line, and the second connection point between the second pixel circuit and the second data line is located at the edge of the second pixel circuit close to the second data line.
[0045] Since in the same pixel circuit column, the layout structure of the first pixel circuit and the layout structure of the second pixel circuit are mirror images of each other along the direction of the pixel circuit column, the first connection point between the first pixel circuit and the first data line is located at the edge of the first pixel circuit close to the first data line, and the second connection point between the second pixel circuit and the second data line is located at the edge of the second pixel circuit close to the second data line, that is, the connection points between each pixel circuit and the data line are close to the corresponding data line, therefore, there is no need for cross-line connection between the data line and the pixel circuit, therefore, the coupling effect between the data line and other signals can be reduced, thereby avoiding the crosstalk problem caused by cross-line connection, and further improving the display performance of the display panel.
[0046] The above is the core idea of this application. The technical solutions in the embodiments of this application will be described clearly and completely below in conjunction with the drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0047] Figure 3 A schematic diagram of a top view of a display panel provided in an embodiment of the present application is shown in FIG. Figure 4 A schematic diagram of a layout structure of a display panel provided in an embodiment of the present application, Figure 5 A schematic diagram of a display panel layout structure provided in an embodiment of the present application. Figures 3 to 5 In one embodiment, a display panel is provided. The display panel includes a plurality of pixel circuit columns, a plurality of first data lines 21 and a plurality of second data lines 22 .
[0048] The pixel circuit column is provided with a first data line 21 and a second data line 22. The first data line 21 and the second data line 22 are respectively used to provide a data signal VData. The first data line 21 and the second data line 22 extend along the pixel circuit column direction Y, respectively, and the first data line 21 and the second data line 22 are respectively arranged along the pixel circuit row direction X. Wherein, Y intersects with X, for example, Y is perpendicular to X. Exemplarily, in the same pixel circuit column, the first data line 21 and the second data line 22 are respectively located on both sides of the pixel circuit column. For example, as Figures 3 to 5 As shown, in the same pixel circuit column, the first data line 21 is located on the left side of the pixel circuit column, and the second data line 22 is located on the right side of the pixel circuit column. It should be noted that the above is only an exemplary description, and the relative position relationship between the first data line 21 and the second data line 22 and the pixel circuit column can also be other layout modes, for example, the first data line 21 is located on the right side of the pixel circuit column, and the second data line 22 is located on the left side of the pixel circuit column. Specifically, a suitable layout mode can be selected according to the actual application scenario, and is not limited here.
[0049] The pixel circuit column includes a plurality of first pixel circuits 110 and a plurality of second pixel circuits 120. In the same pixel circuit column, each first pixel circuit 110 is connected to the first data line 21, and each second pixel circuit 120 is connected to the second data line 22. That is, in the same pixel circuit, the pixel circuit connected to the first data line 21 is the first pixel circuit 110, and the pixel circuit connected to the second data line 22 is the second pixel circuit 120.
[0050] Exemplarily, in the same pixel circuit column, the first pixel circuit 110 and the second pixel circuit 120 are alternately arranged, that is, the first pixel circuit 110 and the second pixel circuit 120 are arranged alternately along the pixel circuit column direction. For example, in the same pixel circuit column, the pixel circuits located in odd rows are the first pixel circuits 110 and are connected to the first data line 21, and the pixel circuits located in even rows are the second pixel circuits 120 and are connected to the second data line 22; or the pixel circuits located in odd rows are the second pixel circuits 120 and are connected to the second data line 22, and the pixel circuits located in even rows are the first pixel circuits 110 and are connected to the first data line 21. It should be noted that, in applications, the first pixel circuit 110 and the second pixel circuit 120 in the same pixel circuit column may not be arranged alternately. For example, multiple first pixel circuits 110 are arranged adjacent to and continuously, and multiple second pixel circuits 120 are arranged adjacent to and continuously, and the multiple first pixel circuits 110 arranged continuously and the multiple second pixel circuits 120 arranged continuously are arranged alternately along the direction of the pixel circuit column. The above are all exemplary descriptions. In applications, the appropriate layout method can be selected for the arrangement of the first pixel circuit 110 and the second pixel circuit 120 according to actual needs, and no limitation is made here.
[0051] The positions of the first pixel circuit 110 and the second pixel circuit 120 in different pixel circuit columns may be the same or different. For example, in each pixel circuit column, the pixel circuits located in odd rows are the first pixel circuits 110 and are connected to the first data line 21, and the pixel circuits located in even rows are the second pixel circuits 120 and are connected to the second data line 22. For another example, in two adjacent pixel circuit columns, the pixel circuits located in odd rows in one pixel circuit column are the first pixel circuits 110 and are connected to the first data line 21, and the pixel circuits located in even rows are the second pixel circuits 120 and are connected to the second data line 22, and the pixel circuits located in odd rows in the other pixel circuit column are the second pixel circuits 120 and are connected to the second data line 22, and the pixel circuits located in even rows are the first pixel circuits 110 and are connected to the first data line 21. It should be noted that the above is only an exemplary description, and the arrangement of pixel circuits in the pixel circuit column may also adopt a combination of the above methods. In applications, the arrangement of pixel circuits in each pixel circuit column in the display panel can be selected according to the actual scenario and is not excessively limited here.
[0052] The layout structure of the first pixel circuit 110 and the layout structure of the second pixel circuit 120 are mirror images of each other along the direction of the pixel circuit column. That is, in the same pixel circuit row, the layout structure of the first pixel circuit 110 and the layout structure of the second pixel circuit 120 are symmetrically arranged along the direction of the pixel circuit column. Moreover, in the same pixel circuit column, the layout structure of the first pixel circuit 110 and the layout structure of the second pixel circuit 120 are symmetrical along the direction of the pixel circuit column.
[0053] The connection point between the first pixel circuit 110 and the first data line 21 is a first connection point 31, and the first connection point 31 is located at the edge of the first pixel circuit 110 close to the first data line 21. The connection point between the second pixel circuit 120 and the second data line 22 is a second connection point 32, and the second connection point 32 is located at the edge of the second pixel circuit 120 close to the second data line 22. For example, Figures 3 to 5 As shown, the first connection point 31 is located at the left edge of the first pixel circuit 110 close to the first data line 21, and the second connection point 32 is located at the right edge of the second pixel circuit 120 close to the second data line 22. It should be noted that the above is only an exemplary description, and in applications, the specific positions of the first connection point 31 and the second connection point 32 can be determined according to factors such as the relative position relationship between the first data line 21 and the second data line 22 and the pixel circuit column, the arrangement of the pixel circuit column, etc., and no excessive limitations are made here.
[0054] It can be understood that the first connection point 31 is located at the edge of the first pixel circuit 110 close to the first data line 21, and the second connection point 32 is located at the edge of the second pixel circuit 120 close to the second data line 22. Therefore, there is no need for a cross-line connection between the first data line 21 and the first pixel circuit 110, and there is no need for a cross-line connection between the second data line 22 and the second pixel circuit 120. That is, there is no need for a cross-line connection between the data line 20 and the corresponding pixel circuit. That is, the data line 20, that is, the connection point is located at the edge of the pixel circuit close to the correspondingly connected data line 20.
[0055] Exemplarily, the first connection point 31 and the second connection point 32 are mirror connection points of each other along the direction of the pixel circuit column. That is, the first connection point 31 and the second connection point 32 are symmetrical. Among them, in the same pixel circuit column, the first connection point 31 and the second connection point 32 are symmetrical along the pixel circuit column. And, in the same pixel circuit row, the first connection point 31 and the second connection point 32 are symmetrically arranged along the direction of the pixel circuit column.
[0056] In the above-mentioned display panel, each pixel circuit column is respectively provided with a first data line 21 and a second data line 22. In each pixel circuit column, each first pixel circuit 110 is respectively connected to the first data line 21, and each second pixel circuit 120 is connected to the second data line 22. The layout structure of the first pixel circuit 110 and the layout structure of the second pixel circuit 120 are mirror images of each other along the direction of the pixel circuit column. In this case, the first connection point 31 between the first pixel circuit 110 and the first data line 21 can be located at the edge of the first pixel circuit 110 close to the first data line 21, and the second connection point 32 between the second pixel circuit 120 and the second data line 22 can be located at the edge of the first pixel circuit 110 close to the first data line 21, and the second connection point 32 between the second pixel circuit 120 and the second data line 22 can be located at the edge of the first pixel circuit 110 close to the first data line 21. The second pixel circuit 120 is close to the edge of the second data line 22, so that when the first data line 21 and the second data line 22 are used to drive the same pixel circuit column, that is, when the dual data line 20 (including the first data line 21 and the second data line 22) is used for driving, the data line 20 does not need to cross the pixel circuit area to connect with the pixel circuit, that is, there is no need for a cross-line connection between the data line 20 and the pixel circuit, which saves space, is beneficial to a display panel with a high pixel density, and reduces the coupling between the data line 20 and other signal lines in the display panel, thereby improving the problem of crosstalk between the data line 20 and other signal lines, thereby improving the display effect of the display panel. In addition, in the same pixel circuit column, the layout structure of the first pixel circuit 110 and the second pixel circuit 120 is designed as a mirror structure, which avoids the data line 20 from crossing the line in the pixel circuit area, reduces the total capacitance of the data line 20, and improves the pixel charging rate, so that the impedance of the fan-out wiring of the display panel can be further increased, and the line width can be further compressed, which is beneficial to the narrow frame design of the display panel.
[0057] Figure 6A schematic diagram of a top view of a display panel provided in an embodiment of the present application. Figure 6 As shown, in one embodiment, the display panel further includes a gating circuit 40. Exemplarily, the gating circuit 40 includes a multiplexer (Demux).
[0058] The first data line 21 and the second data line 22 connected to at least one pixel circuit column are connected to the data signal terminal Data_in via the gating circuit 40. The input terminal of the gating circuit 40 is connected to the data signal terminal Data_in, and the multiple output terminals of the gating circuit 40 are respectively connected to the first data line 21 and the second data line 22 connected to at least one pixel circuit column.
[0059] Each gating circuit 40 is respectively connected to at least one pixel circuit column, that is, each gating circuit 40 can be connected to one or more pixel circuit columns. The pixel circuit columns corresponding to each gating circuit 40 are different from each other, and the data signal terminals Data_in connected to each gating circuit 40 are different from each other. For example, each gating circuit 40 is respectively connected to a pixel circuit column, that is, the first data line 21 and the second data line 22 of a pixel circuit column are connected to the data signal terminal Data_in through the gating circuit 40, that is, the number ratio of the data signal terminal Data_in connected by the gating circuit 40 to the data line 20 is 1:2, which can be recorded as DDL+Demux1:2. For another example, each gating circuit 40 is respectively connected to two adjacent pixel circuit columns, that is, the first data line 21 and the second data line 22 of the two pixel circuit columns are respectively connected to the data signal terminal Data_in through the gating circuit 40, that is, the number ratio of the data signal terminal Data_in connected by the gating circuit 40 to the data line 20 is 1:4, which can be recorded as DDL+Demux1:4. In applications, the connection mode between the first data line 21 and the second data line 22 connected to the pixel circuit column by the selection circuit 40 can be selected according to the actual scenario. The ratio of the number of data signal terminals Data_in connected to the selection circuit 40 and the data lines 20 is 1:n, where n is an even number greater than or equal to 2, that is, DDL+Demux1:n, which is not limited here.
[0060] The data signal terminal Data_in is used to provide a data signal VData. The gating circuit 40 is used to transmit the data signal VData provided by the data signal terminal Data_in to the first data line 21 and the second data line 22 connected to the gating circuit 40 in a time-sharing manner. That is, the gating circuit 40 is used to conduct the paths between the data signal terminal Data_in and the first data line 21 and the second data line 22 in a time-sharing manner, so as to transmit the data signal VData to the first data line 21 and the second data line 22 in a time-sharing manner.
[0061] It should be noted that the number of the gating circuits 40 and the number of the first data lines 21 and the second data lines 22 connected to the gating circuits 40 can be determined according to the actual application scenario. For example, the display panel includes N pixel circuit columns, and each gating circuit 40 is connected to the first data line 21 and the second data line 22 of a pixel circuit column, that is, n=2, then the number of the gating circuits 40 is N. In the application, other methods can also be used. For example, when n=4, the number of the gating circuits 40 is N / 2, etc., which is not excessively limited here.
[0062] In the above-mentioned display panel, the first data line 21 and the second data line 22 connected to at least one pixel circuit column are connected to the data signal terminal Data_in via the selection circuit 40, and the data signal VData provided by the data signal terminal Data_in is transmitted to the first data line 21 and the second data line 22 connected to the selection circuit 40 in a time-sharing manner through the selection circuit 40. In this way, multiple data lines 20 share the same data signal terminal Data_in through the selection circuit 40, which can reduce the number of data signal terminals Data_in, and help to achieve a display panel with a narrow frame and a high pixel density; and can reduce the jump effect caused by the switching of each row of pixel circuits on the same data line 20, thereby improving the circuit stability; in addition, the delay of the data line 20 signal can be reduced, thereby improving the charging efficiency of the pixel circuit, and helping to achieve high-frequency display.

[0106] In the same pixel circuit column, the active layer of the first pixel circuit 110 and the active layer of the second pixel circuit 120 are mirror images of each other along the pixel circuit column direction; that is, the active layer of the first pixel circuit 110 and the active layer of the second pixel circuit 120 are symmetrical along the pixel circuit column direction.
[0107] For example, Fig.13 As shown, in the first pixel circuit column 11 and the second pixel circuit column 12 connected to the gating circuit 40, the active layers of the two adjacent pixel circuits in the same row are mirror-imaged, or symmetrically arranged along the second central axis.

[0110] Exemplarily, for any pixel circuit column, the number of the first data signal output nodes 2112 of the first data line 21 connected thereto and the second data signal output nodes 2212 of the second data line 22 are the same, and are the same as the number of pixel circuits in the pixel circuit column. It should be noted that the first data line body 2111 and the second data line body 2211 can be respectively linear, the first data signal output node 2112 and the second data signal output node 2212 can be respectively cylindrical, and each body and each node can also be any other suitable shape, which is not limited too much here.
[0111] The first data signal output node 2112 is connected to the first data signal VData input node in the first pixel circuit 110 through the first via hole. The first data signal VData input node is located in the active layer of the first pixel circuit 110, and the first data signal VData input node is located at the edge of the active layer of the first pixel circuit 110 close to the first data line 21. The active layer of the first pixel circuit 110 is connected to the first electrode of the data writing transistor T1 in the first pixel circuit 110, so the first data line 21 is connected to the first electrode of the data writing transistor T1 in the first pixel circuit 110 through the first data signal VData node, the first via hole, the first data signal VData input node and the active layer of the first pixel circuit 110, so that the connection between the first pixel circuit 110 and the first data line 21 is realized.

[0112] The second data signal output node 2212 is connected to the second data signal VData input node in the second pixel circuit 120 through the second via hole. The second data signal VData input node is located in the active layer of the second pixel circuit 120, and the second data signal VData input node is located at the edge of the active layer of the second pixel circuit 120 close to the second data line 22. The active layer of the second pixel circuit 120 is connected to the first electrode of the data writing transistor T1 in the second pixel circuit 120, so that the second data line 22 is connected to the first electrode of the data writing transistor T1 in the second pixel circuit 120 through the second data signal VData node, the second via hole, the second data signal VData input node and the active layer of the second pixel circuit 120, thereby realizing the connection between the second pixel circuit 120 and the second data line 22. The second connection point 32 between the second pixel circuit 120 and the second data line 22 can be understood as a connection structure composed of the second data signal output node 2212, the second via hole and the second data signal VData input node.
[0113] It can be understood that the data line 20 and the active layer of the pixel circuit are located in different film layers. Therefore, the embodiment of the present application connects the data signal VData output node and the data signal VData input node through a via, thereby realizing the connection between the data line 20 and the data writing transistor T1 in the pixel circuit. Among them, the number of first vias is the same as the number of correspondingly connected first pixel circuits 110, and the number of second vias is the same as the number of correspondingly connected second pixel circuits 120. The shapes of the first via and the second via can be cylindrical or any other suitable structure, which can be specifically set according to the actual scenario and is not limited too much here.

The data signal output node 2212 is connected to the second data signal VData input node in the second pixel circuit 120 through the second via hole, and is connected to the active layer of the second pixel circuit 120 through the second data signal VData input node, thereby realizing the connection between the second data line 22 and the second pixel circuit 120, and since the second data signal VData input node is located at the edge of the active layer of the second pixel circuit 120 close to the second data line 22, there is no need for a cross-line connection between the second data line 22 and the second pixel circuit 120, thereby avoiding mutual crosstalk between the second data line 22 and other signal lines, reducing the total capacitance of the second data line 22, thereby improving the problem of mutual crosstalk between the data line 20 and other signal lines, improving the display effect, reducing the total capacitance of the data line 20, and improving the pixel charging rate, so that the impedance of the fan-out routing of the display panel can be further increased, and the line width can be further compressed, which is beneficial to the narrow frame design of the display panel.
[0115] Please continue reading Fig.19In one embodiment, the first data signal output node 2112 is located on a side of the first data line body 2111 close to the target pixel circuit column, and the second data signal output node 2212 is located on a side of the second data line body 2211 close to the target pixel circuit column, wherein the target pixel circuit column is connected to the first data signal output node 2112 and the second data signal output node 2212 respectively. The target pixel circuit column is any pixel circuit column in the display panel. In this way, the connection length between the data line 20 and the pixel circuit can be shortened as much as possible, the possibility of crosstalk between the data line 20 and other signal lines is greatly reduced, and the total capacitance of the data line 20 is reduced, which is conducive to the design of display panels with narrow borders, high-frequency display and high pixel density.
[0116] Exemplarily, the first data line 21 and the second data line 22 of the same pixel circuit column are respectively located on both sides of the pixel circuit column, wherein each first data signal output node 2112 is respectively located on one side of the first data line body 2111 close to the pixel circuit column, and each second data signal output node 2212 is respectively located on one side of the second data line body 2211 close to the pixel circuit column. Fig.19 As shown, the first data line 21 connected to the same pixel circuit column is located on the left side of the pixel circuit column, and the second data line 22 is located on the right side of the pixel circuit column, wherein the first data signal output node 2112 is located on the right side of the first data line body 2111 close to the pixel circuit column, and the second data signal output node 2212 is located on the left side of the second data line body 2211 close to the pixel circuit column.
[0117] It should be noted that the above is only an exemplary description. In the application, the relative position relationship between the first data signal output node 2112 and the second data signal output node 2212 and the target pixel circuit column can be determined according to the layout of the pixel circuit column, the first data line 21 and the second data line 22 in the display panel, and is not excessively limited here.
[0118] Please continue reading Fig.19 In one embodiment, the first distance d1 between the first data line body 2111 and the first data signal output node 2112 is the same as, or similar to, the second distance d2 between the second data line body 2211 and the second data signal output node 2212. The first distance d1 and the second distance d2 are respectively smaller than the width of the pixel circuit in the row direction of the pixel circuit. It should be noted that due to other factors such as process preparation accuracy, the first distance d1 and the second distance d2 may be different in the actual manufacturing process, but the error between the first distance d1 and the second distance d2 is less than the set distance threshold, and they can also be regarded as the same. Combined with Figure 2As shown, in the display panel of the related art, among the two data lines 20 connected to the same pixel circuit column, the distance between the main body of one data line 20 and the data signal VData output node connected thereto is greater than the width of the pixel circuit in the pixel circuit row direction.
[0119] Combined with the above comparison, it can be seen that the display panel provided by the embodiment of the present application shortens the distance between the data signal VData output node and the main body of the data line 20, avoids the main body of the data line 20 crossing the pixel circuit to connect with the corresponding data signal VData output node, that is, avoids the cross-line connection between the data line 20 and the pixel circuit, saves space, is conducive to narrow frame and high pixel density display panel, and reduces the coupling capacitance between the data line 20 and other signal lines in the display panel, improves the problem of mutual crosstalk between the data line 20 and other signal lines, and improves the display effect of the display panel. In addition, the total capacitance of the data line 20 is also reduced, the pixel charging rate is improved, so that the impedance of the display panel fan-out line can be further increased, and the line width can be further compressed, which is conducive to the narrow frame design of the display panel.
