Abstract

An Adjustable Segmented Dual Function Mirror with video display (ASDFM) suitable for providing alternatively or simultaneously both a conventional reflected image and a video image under a wide range of ambient lighting condition is disclosed. The ASDFM comprises a two-dimensional connection of traditional mirror segments and dual function mirror segments. Each dual function mirror segment can be rotationally and adjustably connected to the rest of the ASDFM to achieve an optimal visually relevant image-to-ambient contrast for viewing. Alternatively, a position adjustable variable transmissivity screen, a controllable variable transmissivity film or a controllable variable reflectivity film can be included in a dual function mirror segment that is rigidly connected to the rest of the ASDFM for the same purpose. Numerous mechanical, fluid dynamical and electrical implementations are described.
