See-Through Near-Eye Display with Built-in Prescription and Two-Dimensional Exit Pupil Expansion
Applied Sciences, 2020 We propose a see-through near-eye display featuring an exit pupil expander (EPE), which is composed of two multiplexed slanted gratings. Via a two-dimensional expansion, the exit pupil (EP) is able to be enlarged up to 10 × 8 mm2.

Depth-Enhanced Holographic Super Multi-View Maxwellian Display Based on Variable Filter Aperture
Micromachines, 2023 The super multi-view (SMV) near-eye display (NED) effectively provides depth cues for three-dimensional (3D) displays by projecting multiple viewpoint images or parallax images onto the retina simultaneously. Previous SMV NED suffers from a limited depth
