Abstract
Projection system based on microdisplays have the advantage of lower cost and weight due to the reduction in size of the image generating devices and associated optics. Reflective devices are favored because the pixel aperture remains high for small pixels. However, at high resolution the performance is compromised by the reduction in size of the pixel. Increased diffraction loss with reduction in pixel size reduces the optical throughput of the projector. Electric field fringing is enhanced for smaller pixels in liquid crystal devices, sacrificing throughput in general. Computed diffraction losses are presented for a range of pixel geometry and projection f/numbers. An approximation for fringe field modulation is used to estimate throughput losses associated with field fringing.
