Furthermore, the sub-compensation structures 31 and the sub-color resistance structures 41 are arranged at the same layer and sequentially spaced, that is, the sub-compensation structure 31 is located between two adjacent sub-color resistance structures 41, so that the overall thickness of the display panel is reduced.
Optionally, as shown in fig. 4, the color-resist layer 40 includes a red sub-color-resist structure 41R, a green sub-color-resist structure 41G, and a blue sub-color-resist structure 41B, and the light emission colors of the first sub-pixels 101 are the same, or, as shown in fig. 5, the first sub-pixels 101 include a red sub-pixel 101R, a green sub-pixel 101G, and a blue sub-pixel 101B. The vertical projection of the red photon color resistance structure 41R on the plane of the flexible substrate 10 covers the vertical projection of the red photon pixel 101R on the plane of the flexible substrate 10, the vertical projection of the green photon color resistance structure 41G on the plane of the flexible substrate 10 covers the vertical projection of the green photon pixel 101G on the plane of the flexible substrate 10, and the vertical projection of the blue photon color resistance structure 41B on the plane of the flexible substrate 10 covers the vertical projection of the blue photon pixel 11B on the plane of the flexible substrate 10.
In order to implement color display, the display panel according to the embodiment of the present invention may be configured such that the first sub-pixel 101 includes a red sub-pixel 101R, a green sub-pixel 101G, and a blue sub-pixel 101B.

When the first sub-pixel 101 in the display panel includes the red sub-pixel 101R, the green sub-pixel 101G and the blue sub-pixel 101B, the display effect of the display panel can be further improved by disposing the red sub-color blocking structure 41R, the green sub-color blocking structure 41G and the blue sub-color blocking structure 41B above the corresponding red sub-pixel 101R, the green sub-pixel 101G and the blue sub-pixel 101B.

Because the flexible substrate 10 in the display panel is generally yellow PI, that is, the transmittance of the flexible substrate 10 to visible light with a wavelength of 500nm to 780nm is high, and when ambient light directly passes through the flexible substrate 10, the light received by the photosensitive surface of the camera is more visible light with a wavelength of 500nm to 780nm, and less visible light with a wavelength of 380nm to 500nm, when the camera is used to realize an imaging function, a color shift phenomenon exists due to the difference of ambient light with different wavelength bands received by the photosensitive surface, based on this, the transmittance of the color resistance compensation layer 30 to visible light with a wavelength of 380nm to 500nm is greater than the transmittance of visible light with a wavelength of 500nm to 780nm, and after the external ambient light passes through the color resistance compensation layer 30 and the flexible substrate 10, even if the material selected by the flexible substrate 10 is yellow PI, at this time, the transmittance of the color resistance compensation layer 30 to visible light with a wavelength of 380nm to 500nm, the color cast phenomenon of the shooting result caused by different transmittances of the flexible substrate 10 to the environment light of different wave bands can be well compensated.
Optionally, the ambient light changes Δ u 'v' <1JNCD after passing through the color resistance compensation layer 30 and the flexible substrate 10, wherein JNCD represents a standard value of color accuracy.
Experiments show that the color resistance compensation layer 30 arranged in the display panel can well neutralize the color cast problem of the environment light which directly penetrates through the yellow flexible substrate 10, and the color change delta u 'v' <1JNC of the environment light after passing through the color resistance compensation layer 30 and the flexible substrate 10 is 0.004, so that the effect of shooting pictures of the camera is improved.

Furthermore, the difference of the transmittance of the composite transmission structure of the color resistance compensation structure 30 and the flexible substrate 10 is set to be less than 10%, that is, the difference between the visible light and the maximum transmittance and the minimum transmittance of the composite transmission structure formed by the color resistance compensation structure 30 and the flexible substrate 10 is less than 10%, so that the uniformity of the ambient light received by the camera is ensured, and the problem that the imaging quality of the photo is affected due to the uneven brightness of the ambient light received by the camera caused by the large transmittances of the color resistance compensation structure 30 and the flexible substrate 10 in a partial region and the small transmittances of the color resistance compensation structure 30 and the flexible substrate 10 in the partial region is avoided. Further, the uniformity of the display screen of the first display area 100 is ensured.
Optionally, the thickness L of the color resistance compensation layer 30 satisfies that L is greater than or equal to 0.2um and less than or equal to 0.5 um.
Thickness L that sets up color resistance compensation layer 30 satisfies that 0.2um is less than or equal to L and is less than or equal to 0.5um, guaranteed promptly when display panel is in the imaging mode, the ambient light that light passes through the photosurface of camera behind color resistance compensation layer 30 and the flexible substrate 10 is white light, avoid the colour cast problem that the camera exists under the imaging mode, it is thicker to have avoided the color resistance compensation layer 30 thickness that sets up again, thereby the lower transmissivity behind color resistance compensation layer 300 of light of first subpixel 101 outgoing has influenced the display effect of first display area 100.
