As shown in fig. 2, a plurality of pixel structures 30 are arranged in an array on the substrate 20, each pixel structure 30 includes four different sub-pixels, as shown in fig. 3, which are a first edge sub-pixel 31, a second edge sub-pixel 32, a third edge sub-pixel 33 and a central sub-pixel 34, respectively, the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 are arranged around the central sub-pixel 34, so that the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 are all arranged adjacent to the central sub-pixel 34, and the central sub-pixel 34 is a white sub-pixel, therefore, when the central sub-pixel 34 emits white light, the central sub-pixel 34 can provide the same luminance contribution to the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 around the central sub-pixel 34, thereby improving the uniformity of the luminance distribution in each pixel structure 30, the uniformity of the brightness distribution in the whole display substrate can be improved; in addition, in the pixel structure 30, the white sub-pixel is disposed adjacent to each edge sub-pixel, so that the brightness of the edge sub-pixel is improved, and the color shift problem occurring when the white sub-pixel is disposed adjacent to only a part of the edge sub-pixels is avoided.
The pixel structure 30 actually includes an anode layer and a pixel defining layer disposed on the substrate 20, the pixel defining layer partially covering the anode layer and having a plurality of pixel openings exposing the anode layer, the pixel structure 30 further includes a light emitting layer disposed in the pixel openings, and a cathode layer covering the light emitting layer and the pixel defining layer.
Accordingly, the formation process of the pixel structure 30 is as follows: the method comprises the steps of forming an anode film on a substrate 20, patterning the anode film to obtain an anode layer, forming a pixel defining layer film on the anode layer and the substrate 20, patterning the pixel defining layer film to obtain a pixel defining layer, forming a light emitting layer in the pixel opening by an evaporation process or an inkjet printing process, and forming a cathode layer covering the light emitting layer and the pixel defining layer.
It should be noted that, in the pixel structure 30, the material of the light emitting layer in different pixel openings is different, so that edge sub-pixels emitting different color light can be formed, and the manufacturing sequence of various edge sub-pixels in the pixel structure 30 is not limited in this embodiment of the present invention.
For example, the light-emitting layers may be formed in the order of the second edge sub-pixel 32, the third edge sub-pixel 33, the first edge sub-pixel 31, and the center sub-pixel 34, or the light-emitting layers may be formed in the order of the center sub-pixel 34, the first edge sub-pixel 31, the second edge sub-pixel 32, and the third edge sub-pixel 33.
In the embodiment of the present invention, two adjacent pixel structures 30 share one edge sub-pixel, which is any one of the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33, that is, two adjacent pixel structures 30 share one first edge sub-pixel 31, or two adjacent pixel structures 30 share one second edge sub-pixel 32, or two adjacent pixel structures 30 share one third edge sub-pixel 33.
By sharing one edge sub-pixel with the adjacent pixel structures 30, the utilization rate of the edge sub-pixel is improved, the space utilization rate of the display substrate is also improved, more pixel structures 30 can be arranged on each display substrate, and the resolution of the display substrate is further improved as more pixel structures 30 can be arranged on each display substrate.
The first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 in the pixel structure 30 are all disposed around the center sub-pixel 34, the first edge sub-pixel 31 is disposed adjacent to the second edge sub-pixel 32 and the third edge sub-pixel 33, the second edge sub-pixel 32 is disposed adjacent to the first edge sub-pixel 31 and the third edge sub-pixel 33, and the third edge sub-pixel 33 is disposed adjacent to the first edge sub-pixel 31 and the second edge sub-pixel 32.
The shape enclosed by the orthographic projection of the pixel structure 30 on the substrate 20 is a hexagon, which actually means that the shape enclosed by the orthographic projection of the side wall of the pixel structure 30, which is far away from the central sub-pixel 34, on the substrate 20 is a hexagon.
The sidewalls of the pixel structure 30 facing away from the central sub-pixel 34 include a first sidewall of the first edge sub-pixel 31 facing away from the central sub-pixel 34, a second sidewall of the second edge sub-pixel 32 facing away from the central sub-pixel 34, and a third sidewall of the third edge sub-pixel 33 facing away from the central sub-pixel 34, and after the orthographic projection of the first sidewall on the substrate 20, the orthographic projection of the second sidewall on the substrate 20, and the orthographic projection of the third sidewall on the substrate 20 extend along their respective directions, the orthographic projections of the sidewalls of any two adjacent edge sub-pixels on the substrate 20 intersect, and then the shape enclosed by the orthographic projections of the sidewalls of all two adjacent edge sub-pixels on the substrate 20 intersect is a hexagon.
In addition, since the pixel structure 30 formed by using the hexagon in the same space has a hexagonal shape as the orthogonal projection of the pixel structure 30 on the substrate 20, the material cost is reduced because the material required for the first edge sub-pixel 31, the second edge sub-pixel 32, and the third edge sub-pixel 33 in the pixel structure 30 corresponding to the hexagon is minimized compared with the pixel structure 30 formed by using other shapes.
In the embodiment of the present invention, the orthogonal projection shape of the central sub-pixel 34 on the substrate base plate 20 is a hexagon, and the orthogonal projection shapes of the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 on the substrate base plate 20 are all quadrangles.
In the embodiment of the present invention, an orthogonal projection of the central sub-pixel 34 on the substrate 20 is a hexagon, the hexagon is located in a hexagon formed by an orthogonal projection of the pixel structure 30 on the substrate 20, each side of the hexagon corresponds to an orthogonal projection of any one of an orthogonal projection of the first edge sub-pixel 31, an orthogonal projection of the second edge sub-pixel 32, and an orthogonal projection of the third edge sub-pixel 33, in the hexagon corresponding to the orthogonal projection of the central sub-pixel 34 on the substrate 20, and the edge sub-pixels distributed around the central sub-pixel 34 include the first edge sub-pixel 31, the second edge sub-pixel 32, and the third edge sub-pixel 33.
The orthographic projection shapes of the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 on the substrate base plate 20 are all quadrangles, and the quadrangles can be squares, rectangles, parallelograms or the like.
The quadrangle corresponding to the orthographic projection of the first edge sub-pixel 31 on the substrate 20, the quadrangle corresponding to the orthographic projection of the second edge sub-pixel 32 on the substrate 20, and the quadrangle corresponding to the orthographic projection of the third edge sub-pixel 33 on the substrate 20 may be the quadrangles with the same shape or the quadrangles with different shapes, which is not limited in the embodiment of the invention.
By arranging the center sub-pixel 34 in a hexagonal shape, the center sub-pixel 34 can be better adjacent to the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 which surround the center sub-pixel, so that the uniformity of the display brightness of the display panel is improved, and the color cast problem is avoided.
Further, each pixel structure 30 includes two first edge sub-pixels 31, two second edge sub-pixels 32, two third edge sub-pixels 33, and a center sub-pixel 34; the colors of the light rays emitted by the first edge sub-pixel 31, the second edge sub-pixel 32, the third edge sub-pixel 33 and the center sub-pixel 34 are all different; in the pixel structure 30, the same type of edge sub-pixels are oppositely disposed.

That is, the two first edge sub-pixels 31 are disposed to face each other, the two second edge sub-pixels 32 are also disposed to face each other, and the two third edge sub-pixels 33 are also disposed to face each other.
In addition, the colors of the light emitted by the first edge sub-pixel 31, the second edge sub-pixel 32, the third edge sub-pixel 33 and the central sub-pixel 34 are different, so that different edge sub-pixels can be controlled to be combined to emit light with different colors, and the color of the display panel is richer when the display panel displays the light.
In the embodiment of the present invention, the subpixels arranged in the vertical direction along the target edge subpixel include the target edge subpixel and the center subpixel 34; the target edge subpixel is any one of the first edge subpixel 31, the second edge subpixel 32, and the third edge subpixel 33.

In the embodiment of the present invention, each pixel structure 30 includes pixel units located in the same column and two adjacent rows, and each pixel unit includes a first edge sub-pixel 31, a second edge sub-pixel 32, and a third edge sub-pixel 33; in the pixel structures 30 located in the odd columns, the pixel structures 30 in the nth row include pixel units located in the 2N-1 st row and pixel units located in the 2N nd row, and the pixel units in the 2N-1 st row and the pixel units in the 2N nd row share the central sub-pixel; in the pixel structures 30 located in even columns, the pixel structures 30 in the nth row include pixel units located in the 2 nth row and pixel units located in the 2N +1 th row, and the pixel units in the 2 nth row and the pixel units in the 2N +1 th row share a central sub-pixel, where N is a positive integer.
In the embodiment of the present invention, the display substrate includes a plurality of pixel structures 30 arranged in an array, and each pixel structure 30 includes two first edge sub-pixels 31, two second edge sub-pixels 32, and two third edge sub-pixels 33, and each pixel unit includes one first edge sub-pixel 31, one second edge sub-pixel 32, and one third edge sub-pixel 33 by dividing one pixel structure 30 into two pixel units. Therefore, one pixel structure 30 includes two pixel units, and the two pixel units are located in the same column and two adjacent rows.
The pixel structure 30 in the display panel comprises a pixel structure 30 positioned in an even column and a pixel structure 30 positioned in an odd column, and in the pixel structure 30 positioned in the odd column, for the pixel structure 30 positioned in the nth row in the pixel structure 30 positioned in the odd column, the pixel structure 30 comprises two pixel units positioned in two adjacent rows, which are respectively the pixel unit in the 2N-1 th row and the pixel unit in the 2N-1 th row.
For example, in the pixel structure 30 located at column 1, row 2, as shown in fig. 2, the pixel structure 30 includes a pixel cell a1 located at column 1, row 3 and a pixel cell a2 located at column 1, row 4.
In the pixel structures 30 located in the even columns, for the pixel structures 30 in the nth row of the pixel structures 30 located in the even columns, two pixel units located in two adjacent rows are included in the pixel structures 30, which are the pixel units in the 2 nth row and the pixel units in the 2N +1 th row respectively.
For example, as shown in fig. 2, in the pixel structure 30 located at column 6, row 2, the pixel structure 30 includes a pixel cell A3 located at column 6, row 4 and a pixel cell a4 located at column 6, row 5.
Also, each pixel structure 30 includes a center sub-pixel 34, and the first edge sub-pixel 31, the second edge sub-pixel 32, and the third edge sub-pixel 33 of the two pixel units are disposed around the center sub-pixel 34, such that the pixel units of the 2N-1 th row and the pixel units of the 2N th row in the pixel structure 30 of the same row of the odd-numbered columns share the center sub-pixel 34, and the pixel units of the 2N th row and the pixel units of the 2N-1 th row in the pixel structure 30 of the same row of the even-numbered columns share the center sub-pixel 34.
As shown in fig. 2, the pixel structure 30 located at the 1 st column and the 2 nd row includes a pixel unit a1 at the 1 st column and the 3 rd row and a pixel unit a2 at the 1 st column and the 4 th row which share one central sub-pixel 34, and the pixel structure 30 located at the 6 th column and the 2 nd row includes a pixel unit A3 at the 6 th column and the 4 th row and a pixel unit a4 at the 6 th column and the 5 th row which share one central sub-pixel 34.
Because the pixel units in two adjacent rows in the same pixel structure 30 share the central sub-pixel 34, the edge sub-pixels in the pixel units in two adjacent rows in the same pixel structure 30 can share the light emitted from the common central sub-pixel 34, so that the light emitted by different pixel units in the same pixel structure 30 is more uniform, and the central sub-pixel 34 does not need to be separately arranged for each pixel unit, thereby simplifying the process.
In the embodiment of the invention, any two edge sub-pixels of the same type are arranged in parallel.
In the embodiment of the present invention, for the same pixel structure 30, two first edge sub-pixels 31 are disposed in parallel, two second edge sub-pixels 32 are also disposed in parallel, and two third edge sub-pixels 33 are also disposed in parallel, and meanwhile, for different pixel structures 30, any two first edge sub-pixels 31 are disposed in parallel, any two second edge sub-pixels 32 are also disposed in parallel, and any two third edge sub-pixels 33 are also disposed in parallel.
In the same row or column of pixel units, two first edge sub-pixels 31 are spaced with other edge sub-pixels, two second edge sub-pixels 32 are also spaced with other edge sub-pixels, two third edge sub-pixels 33 are also spaced with other edge sub-pixels, and two central sub-pixels 34 are also spaced with other edge sub-pixels.
In the embodiment of the present invention, the first edge sub-pixel 31 is a red sub-pixel, the second edge sub-pixel 32 is a green sub-pixel, and the third edge sub-pixel 33 is a blue sub-pixel. Accordingly, the color of the light emitted from the first edge sub-pixel 31 is red, the color of the light emitted from the second edge sub-pixel 32 is green, and the color of the light emitted from the third edge sub-pixel 33 is blue.
In the embodiment of the present invention, the first edge sub-pixel 31 is set as a red sub-pixel, the second edge sub-pixel 32 is set as a green sub-pixel, and the third edge sub-pixel 33 is set as a blue sub-pixel, but of course, the first edge sub-pixel 31 may also be a green sub-pixel or a blue sub-pixel, the second edge sub-pixel 32 may also be a red sub-pixel and a blue sub-pixel, and the third edge sub-pixel 33 may also be a red sub-pixel or a green sub-pixel, as long as the first edge sub-pixel 31, the second edge sub-pixel 32, and the third edge sub-pixel 33 are sub-pixels of three different colors, namely, a red sub-pixel, a green sub-pixel, and a blue sub-pixel.
In an alternative embodiment of the present invention, the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 in each pixel structure 30 have equal areas.
The areas of the first edge sub-pixel 31, the second edge sub-pixel 32 and the third edge sub-pixel 33 in each pixel structure 30 are equal, so that the manufacturing of the display substrate is facilitated, the parameter setting of different sub-pixels is not required, and the production efficiency is improved.

In the embodiment of the present invention, the first edge sub-pixel 31 is a red sub-pixel, the second edge sub-pixel 32 is a green sub-pixel, and the third edge sub-pixel 33 is a blue sub-pixel, because the lifetime attenuation speed of the blue sub-pixel is greater than the lifetime attenuation speed of the red sub-pixel and the lifetime attenuation speed of the green sub-pixel, the area of the third edge sub-pixel 33 is set to be greater than the area of the first edge sub-pixel 31 and the area of the second edge sub-pixel 32, so as to prolong the lifetime of the third edge sub-pixel 33, and avoid the phenomenon of color unevenness in the pixel structure 30 caused by too fast lifetime attenuation of the blue sub-pixel.
The area of the first edge sub-pixel 31 is equal to the area of the second edge sub-pixel 32, but the area of the first edge sub-pixel 31 and the area of the second edge sub-pixel 32 may be adjusted according to actual needs, and the area of the first edge sub-pixel 31 and the area of the second edge sub-pixel 32 are not equal, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, the shape of the orthographic projection of the central sub-pixel 34 on the substrate base plate 20 is a regular hexagon; in each pixel structure 30, an angle between any adjacent two of the first edge sub-pixel 31, the second edge sub-pixel 32, and the third edge sub-pixel 33 is 120 °.

The angle between the first edge sub-pixel 31 and its adjacently arranged second edge sub-pixel 32 in each pixel structure 30 is 120 °, and the angle between the first edge sub-pixel 31 and its adjacently arranged third edge sub-pixel 33 is also 120 °; the included angle between the second edge sub-pixel 32 and the first edge sub-pixel 31 arranged adjacent to the second edge sub-pixel is 120 degrees, and the included angle between the second edge sub-pixel 32 and the third edge sub-pixel 33 arranged adjacent to the second edge sub-pixel is also 120 degrees; the included angle between the third edge sub-pixel 33 and the first edge sub-pixel 31 disposed adjacent to the third edge sub-pixel 33 is 120 °, and the included angle between the third edge sub-pixel 33 and the second edge sub-pixel 32 disposed adjacent to the third edge sub-pixel 33 is also 120 °, so that the shape of the orthographic projection of the pixel structure 30 on the substrate 20 is also a regular hexagon.
