Abstract
A color conversion film includes a substrate, a number of first and second indentations defined in the substrate, and a number of quantum dot blocks received in the first and second indentations. The substrate includes a first surface and a second surface parallel to the first surface. The first indentations are defined in the first surface and extended towards an interior of the substrate. The second indentations are defined in the second surface and extended towards an interior of the substrate. The quantum dot blocks converts an incident light to a light with a specific color.
Claims7
A color conversion film comprising:
- a substrate, the substrate comprising a first surface and a second surface, the first surface and the second surface being on two opposite sides facing away from each other;
- and
- a plurality of quantum dot blocks;
- wherein the first surface is an outer topmost surface of the substrate, and the second surface is an outer lowest surface of the substrate;
- wherein a plurality of first indentations is defined in the first surface and a plurality of second indentations is defined in the second surface;
- and
- wherein the plurality of quantum dot blocks is positioned in the plurality of first indentations and in the plurality of second indentations to convert an incident light on the color conversion film to colored light;
- the color conversion film further comprises a first passivation layer on the first surface and a second passivation layer on the second surface to seal the quantum dot blocks in the plurality of first indentations and the plurality of second indentations;
- wherein each of the plurality of first indentations does not extend through to the second surface, a first distance is defined between a bottom of each of the plurality of first indentations and the second surface, each of the plurality of second indentations does not extend through to the first surface, and a second distance is defined between a bottom of each of the plurality of second indentations and the first surface.
A display panel comprising:
- a backlight module emitting a monochromatic light;
- and
- a color conversion film set at a light output side of the backlight module, the color conversion film comprising:
