Abstract:
Emissive micro-pixel spatial light modulators with non-telecentric emission are introduced. The individual light emission from each multi-color micro-scale emissive pixel is directionally modulated in a unique direction to enable application-specific non-telecentric emission pattern from the micro-pixel array of the emissive spatial light modulator. Design methods for directionally modulating the light emission of the individual micro-pixels using micro-pixel level optics are described. Monolithic wafer level optics methods for fabricating the micro-pixel level optics are also described. An emissive multi-color micro-pixel spatial light modulator with non-telecentric emission is used to exemplify the methods and possible applications of the present invention: ultra-compact image projector, minimal cross-talk 3D light field display, multi-view 2D display, and directionally modulated waveguide optics for see-through near-eye displays.
