Abstract

See full text

A display device includes a light source device, and a color converter optically coupled with the light source device. An array of regions of the light source device is configured to emit light of a first color. The color converter includes an array of color conversion regions including color conversion regions of a first type and of a second type. The color conversion regions of the first type are configured to convert the light of the first color into light of a second color. The color conversion regions of the second type are configured to convert the light of the first color into light of a third. A respective color conversion region of the array of color conversion regions includes a respective photonic crystal structure defining a respective two-dimensional pattern including one or more induced defects, and a color conversion matrix that includes color converting nanoparticles.
