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 multi-layer stack and a first substrate configured to support the first light source. The multi-layer stack includes an organic phosphor film or a quantum dot (QD) based phosphor film configured to emit a first light having a first peak wavelength. The first substrate includes a first control circuitry configured to independently control the first light source. 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 microLED or a miniLED configured to emit a second light having a second peak wavelength that is different from the first peak wavelength. The second peak wavelength can be in the blue wavelength region of the visible spectrum. The second substrate includes a second control circuitry configured to independently control the second light source.
