MEMS display

Light modulator for MEMS display

MEMS light modulator for display

Operating methods of an array of electromechanical pixels resulting in efficient and reliable operation of light modulating elements. The invention simplifies the design of electromechanical light modulators and permits the construction of large size displays with greater mechanical tolerances on glass substrates.

Method of operating an array of electromechanical pixels resulting in efficient and reliable operation of light modulating elements

A display including a light source for generating light, an optical waveguide for receiving and evenly distributing light in a light propagation direction by total internal reflections and a matrix of electromechanical picture elements for modulating light to produce an image.

Display including waveguide, micro-prisms and micro-shutters

A gas discharge addressed display comprising a matrix of micro-mechanical picture elements with optical properties.

Plasma addressed micro-mirror display

Display including waveguide, micro-prisms and micro-mirrors

A back-light assembly for uniformly illuminating large area displays. The back-light assembly includes a uniformly thin waveguide, a reflector and a plurality of light sources evenly distributed along the display area between the waveguide and the reflector. Prismatic facets are provided along the lower surface of the waveguide for effectively coupling light emitted from light sources into the waveguide.

Back-light assembly

A display including a light source for generating light, an optical waveguide for receiving and evenly distributing light in a light propagation direction by total internal reflections and a matrix of picture elements constructed on the upper surface of the waveguide, the picture elements including electrically activated micro-mechanical actuators having optical properties for modulating light to produce an image.

Display

Electromechanical display and backlight

A backlight assembly includes an array of optical waveguides that are arranged in rows and columns. The array of optical waveguides has a planar upper surface substantially comprised of light exit facet of optical waveguides and spaced-apart lower surface substantially comprised of light input facet of optical waveguides. Backlight assembly also includes a light reflector panel that is spaced-apart from the lower surface of the array. Disposed between reflector panel and the lower light input facet of the optical waveguides are light sources. Light sources comprise light emitting diodes having 120 degree emission angles.
