COMPOUND BACKLIGHT WITH EDGE LIGHTING

Abstract: display devices, display systems, backlight assemblies, and methods described herein provide compound backlights with edge lighting. in an aspect, the backlight includes a waveguide, first lights, and an array layer. the first lights are arranged along an edge of the waveguide. each of the first lights transmits light into the waveguide. the array layer is coupled to the waveguide and comprises a reflective layer and second lights. the reflective layer reflects the light transmitted by the first lights into the waveguide. the second lights are arranged between the waveguide and the reflective layer. each of the second lights transmits light into the waveguide layer through the first surface. in a further aspect, the second lights are oriented away from the waveguide and toward the reflective surface. in another aspect, a compound backlight includes a reflective surface, arranged between a waveguide and second lights, that reflects a portion of received light.
