Abstract

A hybrid LED-OLED lighting device includes a waveguide layer, a light-emitting diode (LED) array optically coupled to the waveguide layer, and an organic light-emitting diode (OLED) array. Light emitted from the LED array is provided to an edge of the waveguide layer and light emitted from the OLED array is provided to a first surface of the waveguide layer. Light emitted from the LED array and light emitted from the OLED array passes through a second surface of the waveguide layer opposite the first surface of the waveguide layer, and light emitted from the lighting device comprises the light emitted from the LED array and the light emitted from the OLED array.
