Display devices with different light sources

Abstract

Embodiments of a display device are described. A display device includes first and second sub-pixels. The first sub-pixel includes a first light source having a quantum dot (QD) film, a blocking layer disposed on the QD film, and a first portion of an organic phosphor film disposed on the blocking layer and a first substrate configured to support the first light source. The blocking layer is configured to prevent emission of light from the first portion of the organic phosphor film and the QD film is configured to emit a primary emission peak wavelength in a red, green, cyan, yellow, or magenta wavelength region of an electromagnetic (EM) spectrum. The second sub-pixel includes a second light source and a second substrate configured to support the second light source. The second light source has a second portion of the organic phosphor film disposed adjacent to the QD film. The second portion of the organic phosphor film is configured to emit a primary emission peak wavelength in a blue, violet, or ultraviolet wavelength region of an EM spectrum.
