Abstract

Conventionally, LCoS, μ-LEDs, and LBS are the principal micro-displays used in Near-Eye displays. We propose an alternative display concept, which offers increased flexibility for its integration with the optical combiner, resulting in a more efficient energy yield. The concept is based on photonic integrated circuits (PIC) in the visible range, active light extraction components using liquid crystals, and pixelated holograms. The combination of these elements enables the generation of an emissive point, whose properties: position, emission angle, and divergence are adjustable. We describe our concept and compare the expected performances with conventional solutions.
