The encapsulation layer 40 is disposed on a side of the pixel layer 30 facing away from the substrate 10. The optical adjustment layer 50 is disposed on the package layer 40 or on a side of the package layer 40 away from the substrate 10, the optical adjustment layer 50 is located in the first sub-display area 1011, and an orthogonal projection of the optical adjustment layer 50 on the substrate 10 at least partially covers an orthogonal projection of the first display portion 3111 on the substrate 10.

It is understood that, in the embodiment of the present invention, the light shielding layer 80 is located in the special-shaped non-display region 103, the special-shaped edge 102 is located between the special-shaped non-display region 103 and the first sub-display region 1011, and the special-shaped edge 102 has a circular arc line and/or a diagonal line that is not structurally matched with the first pixel 31, and since the special-shaped edge 102 is included in the special-shaped non-display region 103, a portion of the first pixel 31 is shielded by the light shielding layer 80 to form the first shielding portion 3112. It should be noted that the first pixel 31 in the first sub-display area 1011 in fig. 1 is not drawn to a real scale.
In the display panel 100 provided by the embodiment of the invention, the optical adjusting layer 50 is disposed on the package layer 40 or on a side of the package layer 40 away from the substrate 10, and the orthographic projection of the optical adjusting layer 50 on the substrate 10 at least partially covers the orthographic projection of the first display portion 3111 on the substrate 10, so that light emitted by at least one sub-pixel can be adjusted, and color cast and cross color generated by the change of luminous efficiency due to the fact that at least one sub-pixel in the first pixel 31 includes a shielding portion are reduced, thereby improving the color cast and cross color problem of the first sub-display area 1011, improving the user experience, and improving the display effect of the display panel 100.
In some alternative embodiments, the light adjusting layer 50 includes a light-adding layer 51 and/or a light-reducing layer 52, and the light-adding layer 51 is used for enhancing the light emitted by at least one sub-pixel, so as to reduce the color shift and the color cross caused by the reduction of the light emission due to the shielding part included in the sub-pixel; the light reduction layer 52 is used for shielding at least one sub-pixel to reduce the light emitted by the at least one sub-pixel, so that the first display portion 3111 in the plurality of sub-pixels can cooperate with each other to satisfy the light emitting efficiency of the normal display of the pixel, thereby reducing the color shift and cross color problem of the first sub-display area 1011.
Referring to fig. 2, optionally, the optical adjustment layer 50 includes a light enhancement layer 51 and a light reduction layer 52, and an orthogonal projection of the light enhancement layer 51 on the substrate 10 and an orthogonal projection of the light reduction layer 52 on the substrate 10 do not overlap. Specifically, some of the first pixels 31 may be matched with the light intensifying layer 51 according to the user's requirement, and other first pixels 31 may be matched with the light reducing layer 52, and by reasonably setting the light adjusting layer 50, the light emitting efficiency of the plurality of sub-pixels in the first pixels 31 may be reasonably adjusted, thereby effectively solving the color shift and cross color problems of the display panel 100.
Referring to fig. 2 and 3 together, in some alternative embodiments, the plurality of sub-pixels include a first sub-pixel 311, the optical adjustment layer 50 includes a light-enhancing layer 51, the whole of the first sub-pixel 311 is the first display portion 3111, and a forward projection of the light-enhancing layer 51 on the substrate 10 does not overlap with a forward projection of the first sub-pixel 311 on the substrate 10.
Since the whole of the first sub-pixel 311 is the first display portion 3111, that is, the whole of the first sub-pixel 311 is disposed in the first sub-display area 1011, when at least one of the rest of the sub-pixels in the plurality of sub-pixels includes the first shielding portion 3112, the light emitting intensity of the sub-pixel including the first shielding portion 3112 is reduced, thereby causing problems of color shift, color crosstalk, and the like. Therefore, in the embodiment of the present invention, the sub-pixel including the first shielding portion 3112 is matched with the light-adding layer 51, so that the luminous intensity of the sub-pixel including the first shielding portion 3112 is enhanced, thereby improving the color shift and the cross color problem of the first sub-display area 1011. When the whole of the first sub-pixel 311 is the first display portion 3111, in order to improve the color shift and the cross color problem of the first sub-display area 1011 more effectively, the emission intensity of the first sub-pixel 311 is prevented from being further enhanced by making the orthographic projection of the prism layer 51 on the substrate 10 not overlap with the orthographic projection of the first sub-pixel 311 on the substrate 10.
Referring to fig. 4, in some embodiments, the plurality of sub-pixels include a first sub-pixel 311, a second sub-pixel 312, and a third sub-pixel 313, each of the first sub-pixel 311, the second sub-pixel 312, and the third sub-pixel 313 includes a first shielding portion 3112 and a first display portion 3111 adjacent to each other, a forward projection of the light-intensifying layer 51 on the substrate 10 covers a forward projection of the first display portion 3111 of the first sub-pixel 311 on the substrate 10, and/or a forward projection of the light-intensifying layer 51 on the substrate 10 covers a forward projection of the first display portion 3111 of the second sub-pixel 312 on the substrate 10, and/or a forward projection of the light-intensifying layer 51 on the substrate 10 covers a forward projection of the first display portion 3111 of the third sub-pixel 313 on the substrate 10. The light extraction of the first sub-pixel 311, the second sub-pixel 312 and the third sub-pixel 313 can be enhanced by the arrangement of the light enhancement layer 51, so that the first sub-pixel 311, the second sub-pixel 312 and the third sub-pixel 313 are better matched with each other to realize the display luminescence of the first sub-display area 1011.
In a specific implementation, the orthographic projection of the light-enhancing layer 51 on the substrate 10 can simultaneously cover the orthographic projection of the first display portion 3111 of the first sub-pixel 311 on the substrate 10, the orthographic projection of the first display portion 3111 of the second sub-pixel 312 on the substrate 10 and the orthographic projection of the first display portion 3111 of the third sub-pixel 313 on the substrate 10. Of course, one of the sub-pixels with a larger area of the first shielding portion 3112 may be enhanced according to the user's requirement, as long as the color shift and cross color problem of the display panel 100 can be improved.
The light-enhancing layer 51 may be formed of scattering particles, which may be silicone coated with small-particle-size inorganic particles, such as organotrialkoxysilane monomers coated with silica particles. In some embodiments, when the small-particle-size inorganic particles are coated in the organic silicon, the small-particle-size inorganic particles are coated in the organic silicon with a larger particle size, so that light can be reflected on the surface of the inorganic particles when passing through the organic silicon, and the light can be scattered more widely, thereby achieving the effect of enhancing the light emission.
In some optional embodiments, referring to fig. 2 and fig. 5, in some optional embodiments, the plurality of sub-pixels include a first sub-pixel 311, a second sub-pixel 312, and a third sub-pixel 313 with different colors, at least one of the first sub-pixel 311, the second sub-pixel 312, and the third sub-pixel 313 includes a first shielding portion 3112, and the first sub-pixel 311, the second sub-pixel 312, and the third sub-pixel 313 include a first display portion 3111. The orthographic projection of the light-reducing layer 52 on the substrate 10 covers the orthographic projection of the first display portion 3111 of the first sub-pixel 311 on the substrate 10, and the orthographic projection of the light-reducing layer 52 on the substrate 10 covers the orthographic projection of the first display portion 3111 of the second sub-pixel 312 on the substrate 10; and an orthographic projection of the light-reducing layer 52 on the substrate 10 covers a portion of an orthographic projection of the first display portion 3111 of the third sub-pixel 313 on the substrate 10. The first display portions 3111 of the sub-pixels are partially shielded by the light reduction layer 52 to adjust and control the light emitting areas of the sub-pixels in the same first pixel 31, so that the light emitting areas of the sub-pixels are better matched, normal display in the first pixel 31 is realized, and the problem of color cast or cross color is reduced.
The light reducing layer 52 may be an ink jet printing structure. It can be understood that the ink-jet printing technology can be programmed to set the printing area, and the ink-jet printing can be performed along an irregular track, so that the light-reducing layer 52 formed by the ink-jet printing technology can more accurately partially shield the first display portion 3111 of the first pixel 31, so that the light-emitting areas of the plurality of sub-pixels can be better matched, and the normal display in the first pixel 31 can be realized, so as to reduce the color cast or cross color problem.
Optionally, the display region 101 further includes a second sub-display region 1012 adjacent to the first sub-display region 1011, the pixel layer 30 further includes a third pixel 33 disposed in the second sub-display region 1012, and the third pixel 33 includes a first light emitting element 331 having the same color as the first sub-pixel 311, a second light emitting element 332 having the same color as the second sub-pixel 312, and a third light emitting element 333 having the same color as the third sub-pixel 313.
The first sub-pixel 311, the second sub-pixel 312 and the third sub-pixel 313 each include a light-emitting area 3113 and a non-light-emitting area 3114 with complementary shapes, and the light-emitting area 3113 and the non-light-emitting area 3114 are located in the first display portion 3111. Specifically, referring to fig. 2, the first display portion 3111 of the first sub-pixel 311, the first display portion 3111 of the second sub-pixel 312 and the first display portion 3111 of the third sub-pixel 313 each include a light emitting region 3113 and a non-light emitting region 3114 with complementary shapes, and the orthographic projection of the light reducing layer 52 on the substrate 10 covers the orthographic projection of the non-light emitting region 3114 on the substrate 10. The ratio of the area of the light-emitting region 3113 of the first sub-pixel 311, the area of the light-emitting region 3113 of the second sub-pixel 312, and the area of the light-emitting region 3113 of the third sub-pixel 313 is the same as the ratio of the area of the first light-emitting element 331, the area of the second light-emitting element 332, and the area of the third light-emitting element 333. The area of each color light-emitting element is the area of the orthographic projection of the color light-emitting element on the substrate 10, and the area of the light-emitting region 3113 of each color sub-pixel is the area of the orthographic projection of the light-emitting region 3113 of each color sub-pixel on the substrate 10.
The second sub-display region 1012 is the normal light emitting display region 101, that is, the third pixel 33 is not shielded, the third pixel 33 located in the second sub-display region 1012 can emit light normally, and the light emitting elements in the third pixel 33 cooperate with each other to realize the light emitting display of the second sub-display region 1012. When a plurality of sub-pixels are included in a pixel, the area ratio of the plurality of sub-pixels affects the light emission color and the light emission efficiency of the entire pixel.
