Abstract: This disclosure provides devices, apparatuses and methods of providing an optical filter with quantum dot films for converting a first wavelength of light to a second wavelength of light. The optical filter includes a plurality of high refractive index layers and a plurality of low refractive index layers alternatingly disposed between the high refractive index layers. Quantum dots are dispersed in either the high refractive index layers or the low refractive index layers. In some implementations, the quantum dots are capable of absorbing blue light and emitting green light. Thus, the optical filter can be part of a red-green-blue lighting device that includes a first blue LED optically coupled with the optical filter to produce green light, a red LED and a second blue LED.

Abstract: This disclosure provides systems, methods and apparatus for image displays incorporating color selective reflectors. The display apparatus includes a substantially monochromatic light source capable of outputting a substantially monochromatic light. The display apparatus incorporates a color conversion material capable of converting at least a portion of the substantially monochromatic light output by the substantially monochromatic light source into light associated with at least one subfield color. The display device also includes a plurality of pixels, each pixel including at least two color-selective reflectors, each color-selective reflector being capable of passing light of a respective subfield color and reflecting light associated with at least two other subfield colors.
