Abstract:
The disclosed examples relate to various implementations of a micro-light emitting diode upon which is built a controllable variable optic to provide a chip-scale light emitting device. An example of the controllable variable optic described herein is a controllable electrowetting structure having a leak-proof sealed cell with a first fluid having a first index of refraction and a second fluid having a second index of refraction. The controllable electrowetting structure may be integrally formed on or in a substrate or semiconductor material associated with the micro-light emitting diode in alignment with one or more of the light emitting diodes of the micro-LED device to provide a controllable lighting distribution.
