A display 1201 includes an array of light modulators 1208 that define a display plane, a light guide 1204 and front- and rear-facing reflective surfaces. The light guide 1204 includes a plurality of geometric light redirectors 1206, and at least 50% of the light guide's rear surface is parallel to the display plane. The rear-facing reflective surface is parallel to the display plane and includes a plurality of apertures.

Display apparatus with optical cavities

The invention relates to methods and apparatus for forming images on a display utilizing a control matrix to control the movement of MEMs-based light modulators.

Display methods and apparatus

Circuits for controlling display apparatus

The invention relates to MEMS-based display devices. In particular, the display devices may include actuators having two mechanically compliant electrodes. In addition, bi-stable shutter assemblies and means for supporting shutters in shutter assemblies are disclosed inclusion in the display devices.

Methods and apparatus for actuating displays

Display devices incorporating shutter-based light modulators are disclosed along with methods of manufacturing such devices. The methods are compatible with thin-film manufacturing processes known in the art and result in displays having lower power-consumption.

Display apparatus and methods for manufacture thereof

A new class of compact high-definition electronic projection systems has emerged that are based on microdisplays. Very large scale integration process technology is adapted to fabricate the three classes of microdisplays: (1) transmissive liquid crystal on high-temperature polysilicon/quartz; (2) microelectromechanical devices on silicon; (3) and reflective liquid crystal on silicon. A variety of system architectures are discussed. Key ancillary technologies include small arc lamps, color separation and recombination optics, and rear-projection screens.
