Enhanced wavelength converting structure

Abstract

The present disclosure provides an enhanced wavelength converting structure. The enhanced wavelength converting structure includes a first crosslinked cholesteric liquid crystal layer and a plurality of first quantum dots dispersed in the first crosslinked cholesteric liquid crystal layer. When a first light is incident into the enhanced wavelength converting structure, the plurality of first quantum dots are excited and emit a second light of a wavelength different from a wavelength of the first light, and the second light is toned up via multiple reflections in the first crosslinked cholesteric liquid crystal layer. The present disclosure further provides a luminescent film and a display backlighting unit.
