Abstract

A color converter device includes an array of color conversion regions. The array of color conversion regions includes color conversion regions of a first type and color conversion regions of a second type that is distinct from the color conversion regions of the first type. A respective color conversion region of the array of color conversion regions includes a respective photonic crystal structure defining a respective two-dimensional pattern. The respective color conversion region includes a respective color conversion matrix. The color conversion regions of the first type converts light of a first color into light of a second color that is distinct from the first color and the color conversion regions of the second type converts the light of the first color into light of a third color that is distinct from the first color and the second color.
