Title:
COLOR CONVERSION ASSEMBLY, DISPLAY PANEL AND MANUFACTURING METHOD FOR COLOR CONVERSION ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2021/004097
Kind Code:
A1
Abstract:
Provided are a color conversion assembly, a display panel and a manufacturing method for the color conversion assembly, wherein the color conversion assembly comprises: a color conversion layer (200) comprising an isolation structure (210), a plurality of accommodation spaces (211) enclosed by the isolation structure (210), openings in communication with the accommodation spaces (211), and light conversion units (220) arranged at at least a portion of the openings in the accommodation spaces; a Bragg filter layer (400) comprising a curved filter (410) corresponding to the light conversion units (220), wherein the curved filter (410) is bent in a direction away from the light conversion units (220). The curved filter (410) corresponds to the light conversion units (220), so that light emitted from the light conversion units (220) is directed to the curved filter (410). The curved filter (410) is bent in a direction away from the light conversion units (220) to ensure that the incident angle of light emitted from the light conversion units (220) tends towards being consistent when it enters the curved filter (410), thereby ensuring that the optical path of the light within the curved filter (410) tends towards being consistent, improving the filtering effect of the curved filter (410), reducing light leakage, and preventing light mixing.
