Color conversion assembly, display panel and manufacturing method of color conversion assembly

1. A color conversion assembly, comprising:

a color conversion layer, comprising isolation structures, a plurality of accommodating spaces defined by the isolation structures, openings communicating with respective accommodating spaces, and light conversion units disposed in at least some of the accommodating spaces; and

a Bragg filter layer, comprising curved optical filters disposed corresponding to the light conversion units and bending in a direction away from the light conversion units.

2. The color conversion assembly of claim 1 , further comprising baffles disposed in the accommodating spaces and corresponding to the light conversion units, each baffle is connected to the isolation structures, the baffle is provided with a light exit hole which penetrates through the baffle, and an exit light passing through the light conversion unit exits through the light exit hole.

3. The color conversion assembly of claim 2 , wherein a projection of the curved optical filter obtained by projecting the curved optical filter along a direction perpendicular to the paper direction is arc-shaped.

4. The color conversion assembly of claim 3 , wherein the curved optical filter is formed as at least part of a hemisphere, and the center of the hemisphere is located in the light exit hole.

5. The color conversion assembly of claim 3 , wherein the curved optical filter is formed as a hemisphere.

6. The color conversion assembly of claim 3 , wherein adjacent two curved optical filters intersect.

7. The color conversion assembly of claim 3 , wherein the curved optical filter is formed as a part of a hemisphere, and the curved optical filter and the baffle are spaced apart in a thickness direction of the color conversion assembly.

8. The color conversion assembly of claim 7 , wherein a light blocking member is provided between adjacent two light exit holes, and the light blocking member is connected between the Bragg filter layer and the baffle or between the Bragg filter layer and the isolation structure.

9. The color conversion assembly of claim 2 , wherein the material of the baffle comprises a reflective metal material and/or a light-absorbing material.

10. The color conversion assembly of claim 3 , wherein the Bragg filter layer further comprises a flat portion for connecting adjacent two curved optical filters.

11. The color conversion assembly of claim 1 , wherein the material of the isolation structure comprises a reflective metal material and/or a light-absorbing material.

12. The color conversion assembly of claim 1 , wherein the isolation structure is provided with a reflective metal layer and/or a light-absorbing layer on its outer surface.

13. A display panel, comprising:

a driving backplate, wherein a plurality of light sources are distributed on the driving backplate; and

the color conversion assembly according to claim 1 , wherein the light sources are disposed corresponding to the accommodating spaces.

14. The display panel of claim 13 , wherein:

the color conversion assembly further comprises baffles disposed in the accommodating spaces and corresponding to the light conversion units, each baffle is connected to the isolation structures, and is provided with a light exit hole which penetrates through the baffle, so that an exit light passing through the light conversion unit exits through the light exit hole; and

the light source and the light exit hole are spaced apart in a thickness direction of the display panel, and along the thickness direction, the projection of the light source on the driving backplate and the projection of the light exit hole on the driving backplate are at least partially overlapped.
