1. A near-eye display device, comprising:
- a holographic display system comprising;
a light source configured to emit light that is converging or diverging;
a waveguide configured to be positioned in a field of view of a user'"'"'s eye; and
a digital dynamic hologram configured to receive the light and spatially modulate the light for coupling into the waveguide such that the light propagates through the waveguide.

Abstract
Examples are disclosed that relate to a near-eye display device including a holographic display system. The holographic display system includes a light source configured to emit light that is converging or diverging, a waveguide configured to be positioned in a field of view of a user'"'"'s eye, and a digital dynamic hologram configured to receive the light, and project the light into the waveguide such that the light propagates through the waveguide.

14. A near-eye display device, comprising:
a holographic display system comprising; a waveguide configured to be positioned in a field of view of a user'"'"'s eye; a digital dynamic hologram configured to receive light from a light source, spatially modulate the light, and direct the light toward the waveguide for coupling into the waveguide such that the light propagates through the waveguide toward the user'"'"'s eye; a front light waveguide positioned intermediate the digital dynamic hologram and the waveguide; a front light input coupling hologram configured to receive the light from the light source and couple the light into the front light waveguide; and a front light output hologram configured to couple light out of the front light waveguide to the digital dynamic hologram and make the light converging or diverging. - View Dependent Claims (15, 16, 17)

18. A near-eye display device, comprising:
a holographic display system comprising; a light source comprising optics configured to output converging light; a waveguide positioned in a field of view of a user'"'"'s eye; a digital dynamic hologram configured to receive the converging light and spatially modulate the converging light for coupling into the waveguide such that the light propagates through the waveguide to form an image in the user'"'"'s eye; and a fixed aperture mask positioned between the digital dynamic hologram and the waveguide and configured to block converging light from the light source that is not diffracted by the digital dynamic hologram. - View Dependent Claims (19, 20)
