With continued reference to fig. 1, the area of each first pixel cell 21 is smaller than the area of each second pixel cell 22, and such a structure helps to disrupt the first direction periodic optical diffraction and the second direction periodic optical diffraction. Moreover, each first pixel unit 21 corresponds to the plurality of light extraction structures one by one, so that the emergent light of the first pixel unit 21 is focused, and the light extraction layer 3 can change the direction of the emergent light of the first pixel unit 21, thereby improving the focusing of the emergent light of the first pixel unit 21 from large-angle divergent weak light to small-angle strong light; the position corresponding to the second pixel unit 22 is not provided with a light extraction structure, so that the emergent light of the second pixel unit 22 realizes large-angle display, and on the premise that the light extraction efficiency of the first pixel unit 21 is greater than that of the second pixel unit 22, the area of the first pixel unit 21 is smaller than that of the second pixel unit 22, so that the emergent brightness of the first pixel unit 21 is the same as that of the second pixel unit 22, and when the first pixel unit 21 and the second pixel unit 22 both work, the display panel provided by the embodiment of the invention achieves balanced display.
Since the first pixel unit 21 and the second pixel unit 22 can be controlled by different pixel switches, the first pixel unit 21 and/or the second pixel unit 22 in the display substrate provided in the embodiment of the present invention can be selected to operate according to requirements, and certainly, in order to ensure the display effect of the display panel provided in the embodiment of the present invention when only the first pixel unit 21 or the second pixel unit 22 operates, the first pixel unit 21 and the second pixel unit 22 are alternately arranged along the first direction, and the first pixel unit 21 and the second pixel unit 22 are alternately arranged along the second direction, where the first direction is perpendicular to the second direction.
In another specific embodiment, two first pixel units 21 and two second pixel units 22 are alternately arranged along the first direction, and two first pixel units 21 and two second pixel units 22 are alternately arranged along the second direction, and the specific number of the first pixel units 21 and the second pixel units 22 that are alternately arranged is not particularly limited, as long as the display effect of the display panel provided by the embodiment of the invention when only the first pixel units 21 or the second pixel units 22 are operated is ensured. Of course, the number of the first pixel units 21 and the second pixel units 22 alternately arranged may also be a manner that one first pixel unit 21 and two second pixel units 22 alternately arranged, and the specific number of the first pixel units 21 and the second pixel units 22 alternately arranged is not particularly limited as long as the display effect of the display panel provided by the embodiment of the present invention when only the first pixel unit 21 or the second pixel unit 22 works is ensured.
In order to improve the problem of poor diffraction ghost display, as shown in fig. 2, a transparent region is provided between the first pixel unit 21 and the second pixel unit 22 in the first direction;
the transparent regions include first sub-transparent regions 41 and second sub-transparent regions 42 alternately arranged in the first direction, and the area of the first sub-transparent regions 41 is larger than the area of the second sub-transparent regions 42.
In order to improve the problem of poor diffraction ghost display, as shown in fig. 3, fig. 3 may be a schematic structural diagram of the first pixel unit 21, or may be a schematic structural diagram of the second pixel unit 22, which is not limited herein. At least two first sub-pixels 211 in each first sub-pixel 211 in the first pixel unit 21 have different areas, and at least two second sub-pixels 221 in each second sub-pixel 221 in the second pixel unit 22 have different areas.
Specifically, each of the first pixel units 21 includes a plurality of first sub-pixels 211;
the light extraction structure includes a plurality of sub-structures in one-to-one correspondence with the plurality of first sub-pixels 211, and each sub-structure covers its corresponding first sub-pixel 211 in an orthogonal projection on the substrate base 1. The sub-structure of the light extraction structure is used for changing the direction of the emergent light of the first sub-pixel 211, reducing the included angle between the emergent light of the first sub-pixel 211 and the direction vertical to the substrate 1, and increasing the light extraction efficiency. Such a first sub-pixel 211 corresponds to a sub-structure, which has a better light extraction effect. Of course, the sub-structure may be formed by forming a light extraction structure in a whole layer, that is, one first pixel unit 21 corresponds to one light extraction structure, so that the manufacturing process of the light extraction structure can be simplified.
For example, a plurality of hemispherical microstructures are formed on the side of the sub-structure facing away from the light emitting structure layer 2, and the hemispherical microstructures are protruded along the side facing away from the light emitting structure layer 2. The hemispherical microstructures are adjacently arranged and directly contacted along the first direction and the second direction.

in the region where the second pixel unit 22 is located, as shown in fig. 5, the filling layer 5 is located on the light emitting side of the light emitting structure layer 2.
In particular, with continued reference to fig. 4, the arrows in the figure represent the exit direction of the light rays, and the refractive index of the light extraction structure is greater than the refractive index of the filling layer 5. Because the refracting index of light extraction structure is greater than the refracting index of filling layer 5, consequently the emergent light of first pixel unit 21 is from the light density to the light sparse, incident angle will be less than emergent angle, the light that consequently first pixel unit 21 sent focuses on the positive direction behind the light extraction structure, consequently can not take place the total reflection, the light that basically sends from first pixel unit 21 is all focused and is jetted out via light extraction structure, make optical efficiency strengthen, still satisfy medium-size class product simultaneously, the display demand of notebook small-angle privacy for example.
Specifically, the refractive index of the light extraction structure is 1.8 to 2.2, and the refractive index of the filling layer 5 is 1.5 to 1.6. Of course, the refractive index of the specific light extraction structure may be adjusted as needed, and is not particularly limited herein; also, the refractive index of the filling layer 5 may be adjusted as needed, and is not particularly limited herein.
The display substrate provided by the embodiment of the invention further comprises a protective layer 6;
the protective layer 6 is located on a side of the filling layer 5 facing away from the light emitting structure layer 2.
The display substrate provided by the embodiment of the invention also comprises a thin film packaging layer 7;
in the region of the first pixel unit 21, the thin film encapsulation layer 7 is located between the light emitting structure layer 2 and the light extraction structure;
in the area of the second pixel unit 22, the thin film encapsulation layer 7 is located between the light emitting structure layer 2 and the filling layer 5.
The thin film encapsulation layer 7 protects the organic light emitting structure in the light emitting structure layer 2 from moisture and/or oxygen, thereby improving the service life.
