Augmented Reality (AR) devices optically superimpose information over the real world through an optical channel which angular resolution is limited by total internal reflection in the image guide. This limitation is governed by packaging size, Field of View, resolution, and the brightness. We discuss two multiplexing and de-multiplexing methods to address this challenge. By applying wavelength and time multiplexing, like, what is used in optical communication. Along with diffraction multiplexing via an array of facets, an increase in the effective optical bandwidth for the AR display is demonstrated. The demonstrated hybrid approach NED projection system combines multiple domains of multiplexing to enhance the FOV of displays without the typical package volume and energy consumption trade-offs. Showing the untapped potential of multiplexing on Digital Micro-mirror Devices based near-to-eye displays.
