It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The present application firstly proposes a display panel, referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the display panel of the present application, as shown in fig. 1, the display panel includes a substrate (not shown), and a plurality of pixel groups 11 disposed on the substrate, and a driving circuit (not shown) disposed on the substrate, the driving circuit is used for performing light emission control on organic light emitting devices in sub-pixels, and each pixel group 11 includes a plurality of sub-pixels. In particular, the driving circuit may be configured to provide a corresponding voltage signal, such as an anode voltage signal or a cathode voltage signal, to the anode and/or the cathode in the sub-pixel to control the organic light emitting device to emit light at a desired brightness or to control the organic light emitting device to stop emitting light.
The plurality of pixel groups 11 may include a plurality of rows of pixel groups 11, for example, there are 4 rows of pixel groups 11 in the partial structure of the display panel shown in fig. 1.
Each row of pixel groups 11 may be provided with a plurality of pixel groups 11 along the first direction D1, for example, as shown in fig. 1, in a partial structure of the display panel, each row of pixel groups includes more than two pixel groups 11, and the more than two pixel groups 11 in one row are sequentially arranged along the first direction D1.
The plurality of sub-pixels in each pixel group 11 may specifically include a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113, for example, in a partial structure of the display panel shown in fig. 1, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 in the same pixel group 11 are sequentially arranged along the first direction D1, and in a row of pixel groups 11, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are circularly arranged along the first direction D1. Each subpixel includes an anode and an anode via.

the shapes of the display regions formed by the light emitting layers of the organic light emitting devices in the sub-pixels included in the target pixel unit are all regular patterns with a collective center, such as a centrosymmetric pattern or other regular patterns with a geometric center.
The anode via hole X of each sub-pixel in the target pixel unit is located at the geometric center of the display area of the sub-pixel where the anode via hole X is located, and the anode of the sub-pixel (for example, the sub-pixel a or the sub-pixel B) can pass through the anode via hole X to be connected with a driving circuit arranged on the substrate, so that the anode can receive an anode voltage signal provided by the driving circuit, meanwhile, the cathode of the sub-pixel can be directly connected with the driving circuit without passing through the via hole, so that the cathode can receive a cathode voltage signal provided by the driving circuit, and the driving circuit can control the pixel to perform corresponding light emitting display through the connection.
It should be noted that, by disposing the anode via X in the corresponding display region, compared with disposing the anode via X outside the corresponding display region, the anode can be directly connected to the driving circuit through the anode via X, and it is not necessary to configure a corresponding anode trace connected to the anode to extend from the display region to the outside of the display region to connect the anode and the anode via, and then the anode trace is connected to the driving circuit through the anode via X.
In addition, the anode via holes X of all the sub-pixels in the target pixel unit are respectively arranged at the geometric center of the corresponding display area, so that the diffraction interference phenomenon caused by the fact that the anode via holes X are arranged in the display area in the sub-pixels can be weakened, the negative influence caused by the fact that the anode via holes X are arranged in the display area in the sub-pixels can be minimized, the symmetry of the sub-pixels can be improved by the fact that the anode via holes X are arranged at the geometric center of the regular graph, and the negative influence of the color cast phenomenon caused by the asymmetry of the sub-pixels in the sub-pixels can be minimized.
Different from the prior art, in the technical scheme of the present application, each pixel group includes a first pixel unit, a second pixel unit and a third pixel unit, which are sequentially arranged along a first direction, at least one pixel unit in all pixel units included in each pixel group is a target pixel unit, the target pixel unit includes two sub-pixels, a display area of each sub-pixel in the target pixel unit is a regular figure having a geometric center, each anode via hole in the target pixel unit is respectively located at the geometric center of the corresponding display area, so that the corresponding anode can be connected to the corresponding driving circuit through the anode via hole at the geometric center, based on the above manner, the sub-pixels of a specific color in the display panel can be all the sub-pixels in the target pixel unit, thereby increasing the number of the sub-pixels of the specific color in a single pixel group, furthermore, the pixel density of the sub-pixels with specific colors in the display panel is increased, meanwhile, because the anode via holes of the sub-pixels in the target pixel unit are all arranged in the display area, the number of the sub-pixels in a single target pixel unit is larger than that of the single sub-pixels, the traditional anode routing is not needed to be configured to connect the anode in the display area and the anode via holes outside the display area, the situation that the anode routing occupies more non-display areas is avoided, the aperture ratio of the display panel can be ensured to be higher while the sub-pixels with specific colors in a single pixel group are added, in addition, the anode via holes are arranged in the geometric center of the display area with a regular graph shape, the negative influence corresponding to the color cast phenomenon caused by the diffraction phenomenon or factor pixel asymmetry caused by the anode via holes arranged in the display area can be reduced to the minimum, the display effect of the display panel is prevented from being reduced due to the fact that the anode through holes are formed in the display area of the sub-pixels.

Optionally, in all the sub-pixels, the display area of each sub-pixel is shaped as a regular pattern having a geometric center, and each anode via hole is located at the geometric center of the display area of the corresponding sub-pixel.
Specifically, each sub-pixel in each pixel unit in the single pixel group 11 has a display area in a regular pattern shape, and the anode via hole is located at the geometric center of the corresponding display area, so that each sub-pixel on the display panel does not need to be configured with a corresponding anode wire, the occupation ratio of the display areas of all sub-pixels in the display panel can be increased, the aperture ratio and the PPI of the display panel can be increased, and the display effect of the display panel can be further improved.

In an embodiment, a pixel group 11 of one row of pixels in two adjacent rows of pixel groups 11 at least partially overlaps with a pixel group 11 of the other row of pixels in two adjacent rows of pixel groups 11 in the second direction D2.
Specifically, as shown in fig. 1, in the display panel, the distances between the adjacent pixel groups 11 in each row of the pixel groups 11 are equal, and, in the two adjacent rows of the pixel groups 11, there is a pixel group 11 located in one row of pixels and a pixel group 11 in the other row of pixels, which at least partially overlap in the second direction D2.
Optionally, a pixel group 11 of one row of pixels in two adjacent rows of pixel groups 11 partially overlaps with a pixel group 11 of the other row of pixels in two adjacent rows of pixel groups 11 in the second direction D2.

Based on the above manner, any one of the display panels shown in fig. 1 to 3 can be formed, and the distribution rule of the three sub-pixels is more stray compared with the display panel shown in fig. 4, so that the image displayed by the display panel is finer and smoother, and the display effect of the display panel is improved.
Further, the length of the overlapped portion in the first direction D1 between one pixel group 11 of one row of pixels in the two adjacent rows of pixel groups 11 and one pixel group 11 of the other row of pixels in the two adjacent rows of pixel groups 11 in the second direction D2 is a preset number multiple of the length of one pixel group 11 in the first direction D1, and the preset number is greater than 0 and less than 1.
Specifically, as shown in fig. 1 to 3, the predetermined number is 0.5, that is, a pixel group 11 in the first row of pixels and a pixel group 11 in the second row of pixels have a half portion overlapping in the second direction D2.
The predetermined amount may be 0.5, 0.3, 0.7, or any other value greater than 0 and less than 1, which is not limited herein.
Optionally, a pixel group 11 of one row of pixels in two adjacent rows of pixel groups 11 and a pixel group 11 of the other row of pixels in two adjacent rows of pixel groups 11 are all overlapped in the second direction D2.
Specifically, referring to fig. 3, fig. 3 is a schematic structural diagram of another embodiment of the display panel of the present application, as shown in fig. 3, in the display panel, distances between adjacent pixel groups 11 in each row of pixel groups 11 are equal, and in two adjacent rows of pixel groups 11, there is a pixel group 11 located in one row of pixels and a pixel group 11 in the other row of pixels, which are completely overlapped in the second direction D2.
In one embodiment, the pixel units other than the target pixel unit among the first pixel unit 111, the second pixel unit 112, and the third pixel unit 113 include only one sub-pixel.
Only one of the first pixel unit 111, the second pixel unit 112, and the third pixel unit 113 is a target pixel unit, and the pixel units other than the target pixel unit among the first pixel unit 111, the second pixel unit 112, and the third pixel unit 113 are non-target pixel units.
One pixel group of one row of pixels in the two adjacent rows of pixel groups is partially overlapped with one pixel group of the other row of pixels in the two adjacent rows of pixel groups in the second direction.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a display panel according to still another embodiment of the present disclosure, and as shown in fig. 4, the display panel includes a plurality of driving circuits (not shown) and a plurality of data lines, the data lines are sequentially arranged along a first direction, and the plurality of data lines are divided into a plurality of first data lines and a plurality of second data lines.
The first data lines are respectively connected with the pixel circuits of each sub-pixel in each corresponding target pixel unit, and the second data lines are respectively connected with the pixel circuits of each sub-pixel in each corresponding non-target pixel unit.
Specifically, as shown in fig. 4, the anode of each sub-pixel is connected to the metal layer P in the pixel circuit of one sub-pixel, and each pixel circuit is further used to connect to a corresponding DATA line to receive a corresponding DATA signal, in the display panel shown in fig. 4, the first DATA line DATA1 is connected to the pixel circuit to which the two sub-pixels of the target pixel unit (e.g., the second pixel unit 112 in fig. 4) are respectively connected, the second DATA line DATA2 is connected to the pixel circuits to which the sub-pixels of the non-target pixel unit (e.g., the first pixel unit 111 and the third pixel unit 113 in fig. 4) are respectively connected, and the DATA signals of the DATA lines are respectively provided by corresponding driving circuits, which is not limited herein.
Based on the above mode, when the sub-pixels in the target pixel unit are all green sub-pixels, the data lines for providing data signals for the green sub-pixels are only connected with the green sub-pixels, so that the number of the data lines is as small as possible, the wiring complexity is reduced, and the aperture opening ratio of the display panel is further improved.
In an embodiment, the sub-pixel further comprises a support layer.
The projection of the cross section of at least one anode via hole X on the display area at least partially overlaps the projection of the support layer of the corresponding sub-pixel on the display area.
In particular, the support layer may particularly refer to a PS layer.
The support layer and the pixel via holes are positioned at different layers in the sub-pixels, and the projection of the support layer on the display area is partially or completely overlapped with the projection of the cross section of the anode via hole X on the display area.
In the conventional technology, the support layer is usually disposed between adjacent rows of pixel groups 11, or between adjacent sub-pixels of the same row of pixel group 11, in which case, there is a certain color shift phenomenon in the display of the sub-pixels due to a certain distance between each support column and the center of the display area of the corresponding sub-pixel.
Based on the above manner of overlapping at least part of the projection of the supporting layer and the projection of the anode via hole X, compared with the conventional technique in which the projections of the supporting layer and the pixel via hole on the display area respectively do not overlap, the color shift phenomenon of the display panel can be reduced, and the display effect of the display panel can be improved.
In addition, when the projection of the cross section of at least one anode via hole X on the display area at least partially overlaps with the projection of the support layer of the corresponding sub-pixel on the display area, if the anode via hole X is also located at the geometric center of the corresponding display area, the negative effect of the support layer on the sub-pixel display can be reduced, and the display effect of the display panel is further improved.
Optionally, a projection of the at least one support layer onto the display area of the respective sub-pixel overlaps with a geometric center of the display area of the respective sub-pixel.
Specifically, based on the above manner, the distance between the projection of the support layer on the display area and the geometric center of the display area can be reduced as much as possible, so that the color shift phenomenon caused by the relative distance between the support layer and the geometric center of the sub-pixel is reduced or eliminated, and the display effect of the display panel is improved.
Further, the projection of the at least one support layer on the display area of the respective sub-pixel completely covers the projection of the cross section of the anode via X on the display area of the respective sub-pixel.
Alternatively, the projection of the cross section of the anode via X onto the display area completely covers the projection of the support layer onto the display area.
Specifically, based on the above manner, the area of the overlapping portion between the projection of the support layer on the display area of the corresponding sub-pixel and the projection of the cross section of the anode via hole X on the display area of the corresponding sub-pixel can be maximized, so that the color cast phenomenon is reduced as much as possible, and the display effect of the display panel is improved.

Specifically, the first sub-pixel 111 may be a red sub-pixel, the second sub-pixel 112 may be a green sub-pixel, and the third sub-pixel 113 may be a blue sub-pixel, and may also be other color combinations, which is not limited herein.

Different from the prior art, in the technical scheme of the present application, each pixel group includes a first pixel unit, a second pixel unit and a third pixel unit, which are sequentially arranged along a first direction, at least one pixel unit in all pixel units included in each pixel group is a target pixel unit, the target pixel unit includes two sub-pixels, a display area of each sub-pixel in the target pixel unit is a regular figure having a geometric center, each anode via hole in the target pixel unit is respectively located at the geometric center of the corresponding display area, so that the corresponding anode can be connected to the corresponding driving circuit through the anode via hole at the geometric center, based on the above manner, the sub-pixels of a specific color in the display panel can be all the sub-pixels in the target pixel unit, thereby increasing the number of the sub-pixels of the specific color in a single pixel group, furthermore, the pixel density of the sub-pixels with specific colors in the display panel is increased, meanwhile, because the anode via holes of the sub-pixels in the target pixel unit are all arranged in the display area, the number of the sub-pixels in a single target pixel unit is larger than that of the single sub-pixels, the traditional anode routing is not needed to be configured to connect the anode in the display area and the anode via holes outside the display area, the situation that the anode routing occupies more non-display areas is avoided, the aperture ratio of the display panel can be ensured to be higher while the sub-pixels with specific colors in a single pixel group are added, in addition, the anode via holes are arranged in the geometric center of the display area with a regular graph shape, the negative influence corresponding to the color cast phenomenon caused by the diffraction phenomenon or factor pixel asymmetry caused by the anode via holes arranged in the display area can be reduced to the minimum, the display effect of the display panel is prevented from being reduced due to the fact that the anode through holes are formed in the display area of the sub-pixels. In summary, the above-mentioned method can ensure a high aperture ratio of the sub-pixels and increase the pixel density of the sub-pixels corresponding to the target pixel unit, so as to improve the display effect of the display panel.
