Patent ID: 11101410

Abstract:
Light emitting diode (LED) devices and systems include a superstrate (e.g., a light-transmissive layer), at least one region of wavelength-conversion material in the light-transmissive layer, and LEDs attached to the superstrate at the location of the wavelength-conversion material. An encapsulant layer is formed over and/or around the LEDs with an opaque or clear material. Additional color filter layers are optionally applied to the light-transmissive layer. A method for producing LED devices and systems includes providing a superstrate with a wavelength-conversion material region formed therein, attaching LEDs to the superstrate at the die-attach layer, forming conductive surfaces on a side of the LED opposite the die-attach layer, dispensing an encapsulant layer to at least partially encapsulate the LEDs, and forming one or more electrical traces to electrically interconnect the conductive surfaces of at least some of the LEDs with each other.
