However, since the area of the display panel corresponding to the functional device under the screen needs to have both display and light transmission performance, the device structure or the film structure of the display area corresponding to the functional device is different from the normal display area, which easily causes the difference between the luminance attenuation of the display area corresponding to the functional device and the luminance attenuation of the normal display area under the side viewing angle to be large, and causes the boundary between the display area corresponding to the functional device and the normal display area under the side viewing angle to be obvious, so that the display uniformity of the display panel under the side viewing angle is poor.

The color of the color filter may be set corresponding to the color of the light emitted by the light emitting element, and the filter unit 410 is set corresponding to the light emitting element, which is not limited in this embodiment. The light adjusting structure 500 is disposed between adjacent light filtering units 410, and the light adjusting structure 500 may be used to modulate light irradiated on the light adjusting structure 500. As shown in fig. 2, the outgoing light of the display panel is emitted from the display side D, in the display angle of the display panel, the front light is emitted from the front view of the display side D, the side view light of the side view angle can be modulated by the light of the dimming structure 500, the modulation can be to change the propagation direction of the side view light, block the side view light or absorb the side view light, etc., the modulation of the side view light of the panel by the dimming structure 500 can be balanced, the front view light output and the side view light output of the first display area 100 and the second display area 200 can be balanced, so as to further improve the display uniformity of the front view angle and the display uniformity of the side view angle in the first display area 100 and the second display area 200. Note that the first pixel circuit 111 and the second pixel circuit 211 shown in fig. 2 may be formed by thin film transistors, and embodiments of the present application are not particularly limited. The first sub-pixel 110, the second sub-pixel 210, the color filter 400 and the light modulation structure 500 are disposed on the same side of the substrate 300.
It should be noted that, generally, the light of the side viewing angle in the display panel of the area corresponding to the sub-screen camera can be directly emitted from the side viewing angle, however, in order to prevent glare or light mixing, the light of the side viewing angle in the normal display area can be blocked, and then, at the side viewing angle, the area corresponding to the sub-screen camera looks brighter, i.e., more emergent light quantity, and the normal display area is darker, i.e., less emergent light quantity, than the area corresponding to the sub-screen camera, therefore, at the side viewing angle, a more obvious boundary is formed between the normal display area and the area corresponding to the sub-screen camera, and the display uniformity is poor.

The side view angle and the front view angle of the display panel are relative to the light-emitting side, and the light-emitting side is also the display side.
In view of the above situation, in the display panel provided in the embodiment of the present application, by arranging the first display area 100 and the second display area 200 in the display panel, the light transmittance of the first display area 100 is higher than that of the second display area 200, and the first display area 100 can be used in a setting area corresponding to the functional device.

The light adjusting structure 500 is disposed between the adjacent light filtering units 410, and in the display viewing angle of the display panel, the light adjusting structure 500 in the first display area 100 can modulate the side-view light, and can modulate the light emitted from the side-view angle to tend to be emitted from the front-view angle, so as to reduce the side-view angle light-emitting amount of the first display area 100. The light-adjusting structure 500 in the second display area 200 can block the light emitted from the side-viewing angle, and can reduce the light-emitting amount from the side-viewing angle of the second display area 200, so as to further balance the light-emitting amount from the front-viewing angle and the light-emitting amount from the side-viewing angle of the first display area 100 and the second display area 200. The light-adjusting structure 500 is configured to make the light attenuation of the first display area 100 and the light attenuation of the second display area 200 tend to be consistent in a side-view angle, so as to improve the uniformity of the side-view luminance between the first display area 100 and the second display area 200, and weaken the boundary between the first display area 100 and the second display area 200, that is, improve the display uniformity of the display panel.

By disposing the first pixel circuit 111 in the first display region 100, the first pixel circuit 111 can be electrically connected to the first light emitting element 112 by a via hole, and an electrical connection line is not required, so that the process flow is simple.
Fig. 3 is a schematic structural diagram of another display panel provided in the embodiment of the present application; fig. 4 is a partial cross-sectional view of another display panel provided in an embodiment of the present application.

The conductive line 113 may be made of a transparent electrode without affecting light transmittance.
In some embodiments, fig. 5 is a schematic partial cross-sectional view of another display panel provided in an embodiment of the present application. As shown in fig. 5. The light modulating structure 500 comprises a first light modulating structure 510 and a second light modulating structure 520, the first light modulating structure 510 is located in the first display area 100, and the first light modulating structure 510 is configured to modulate at least part of light emitted by the first light emitting element 112. The second light adjusting structure 520 is disposed in the second display region 200, and the second light adjusting structure 520 is used for shielding a portion of light emitted by the second light emitting element 212. The second light adjusting structure 520 can block the side-looking light F2, so as to block the light passing through between the adjacent light filtering units 410, thereby preventing the light mixing between the adjacent light filtering units 410 and avoiding the problem of color distortion or color saturation reduction. For example, the second dimming structure 520 may include a black light blocking layer, for example, a black light blocking material, and the embodiment of the present application is not limited in particular. The second light adjusting structure 520 may not be disposed in the first display area 100, so that the second light adjusting structure 520 can be prevented from reducing the transmittance of the first display area 100, and the transmittance of the first display area 100 is ensured to be greater than the transmittance of the second display area 200.
For example, the first dimming structure 510 may include at least one of a lens structure and a prism structure, each of which functions to modulate light.

As shown in fig. 5, the first light adjusting structure 510 can make the light rays irradiated on the first light adjusting structure 510 undergo surface reflection, refraction, scattering, etc., so that the side view light rays F2 change the propagation direction after being irradiated on the first light adjusting structure 510, the side view light rays F2 can go out in the direction of the front view light rays F1 through the light modulation of the first light adjusting structure 510, which can reduce the light output amount of the side view angle in the first display area 100 and increase the light output amount of the front view angle in the first display area 100. In combination with the shielding of the second light adjusting structure 520 to the viewing ray F2 inside the second display area 200, the difference between the light output amounts of the first display area 100 and the second display area 200 at the side viewing angle can be reduced, so that the luminance attenuation of the first display area 100 and the second display area 200 at the side viewing angle tends to be uniform.
