Abstract: A method is provided for fabricating an emissive display color conversion film. An emissive substrate top surface is conformally coated with an optically transparent carrier film, covering an array of emissive elements. A suspension, including a fluid and a color conversion material (e.g., QDs), is then selectively deposited in absorption regions overlying the emissive elements, for example, using inkjet patterning. After the suspension is absorbed into the absorption regions, the fluid is removed from the suspension, leaving the color conversion material in the absorption regions, and forming the color conversion film. The removal of the fluid encapsulates the color conversion material in the absorption regions. Typically, the conformal coating is thick enough to form a planar top surface. The conformally coating of carrier film may also act to encapsulate both properly aligned emissive elements, as well as misaligned emissive elements that may be located on the emissive substrate top surface.
