  • a substrate; and

    a plurality of display units on the substrate, wherein each of the plurality of display units comprises;

    a first color sub-pixel, comprising a first quantum dot material and a first light source, wherein the first color sub-pixel is configured to provide a first color light by stimulating the first quantum dot material with the first light source, and the first quantum dot material encases the first light source;

    a second color sub-pixel, comprising a second quantum dot material and a second light source, wherein the second color sub-pixel is configured to provide a second color light by stimulating the second quantum dot material with the second light source, and the second quantum dot material encases the second light source; and

    isolating channels for optically isolating the first color sub-pixel and the second color sub-pixel, each of the isolating channels including an isolating layer below a corresponding light source and one or more isolating walls integrated with the isolating layer, and each of the first quantum dot material and the second quantum dot material being located in one of the isolating channels.
