Abstract: Apparatus and method of making an improved moisture-resistant package for a MEMS device having movable parts, the package including a substrate, a translucent cover over the substrate, a seal and moisture barrier and a plurality of parallel sidewalls around the periphery of the substrate and cover. The sidewalls have ends and an area between the sidewalls, and the sidewalls separate the substrate and cover by a sufficient distance to provide clearance for the movement of the movable parts. The package is sealed using a glue layer that at least partially fills the area between the sidewalls, and lies between the ends of the sidewalls and one of the substrate or cover. The glue layer causes the substrate or cover, respectively, to adhere to the ends of the sidewalls. The glue layer and the sidewalls together prevent moisture from entering the package.

Abstract: A color video projection display system having an improved contrast ratio is disclosed. At least one reflective or transmissive panel, e.g., a liquid crystal on silicon (LCoS) panel, is arranged within the system to receive incident light of one or more designated colors via an input optical path. The reflective or transmissive panel modulates the incident light in accordance with corresponding applied signals, and the resulting modulated light is further processed via an output optical path to generate a viewable display. At least one low-retardance film is arranged within one of (i) the input optical path of the system between an input optical path polarizer and the panel, and (ii) the output optical path of the system between the panel and an output optical path polarizer, so as to increase a contrast ratio of the viewable display. The invention can be implemented in single-panel or multi-panel configurations.
