A projection screen for use in a projection system is described. In an embodiment of the present invention, a projection system includes a projector and a projection screen. The projector is configured to project an image composed of visible light in one or more ranges of wavelengths. The projection screen has a plurality of sub-pixels that reflect and/or transmit the one or more ranges of wavelengths to display the image and absorb visible wavelengths of light in at least one other range not included in the one or more ranges. One or more spaces are defined between adjacent sub-pixels that reflect and/or transmit the one or more ranges and the at least one other range.
Abstract:
A charge control circuit for controlling a micro-electromechanical system (MEMS) device having variable capacitor formed by first conductive plate and a second conductive plate separated by a variable gap distance. The charge control circuit comprises a switch circuit configured to receive a reference voltage having a selected voltage level and configured to respond to an enable signal having a duration at least as long as an electrical time constant constant of the MEMS device, but shorter than a mechanical time constant of the MEMS device, to apply the selected voltage level across the first and second plates for the duration to thereby cause a stored charge having a desired magnitude to accumulate on the variable capacitor, wherein the variable gap distance is a function of the magnitude of the stored charge.
Abstract:
A micro-display has a device chip with a transparent layer overlying one or more micro-electromechanical system devices. A transparent cover overlies the transparent layer. An index-of-refraction-matching medium is interposed between the transparent layer and the transparent cover. An index of refraction of the index-of-refraction-matching medium is substantially equal to an index of refraction of the transparent layer and the transparent cover.

Systems, methodologies, and other embodiments associated with a micro-electrical-mechanical system (MEMS) Fabry-Perot interferometric device (FPID) are described. Fabricating a MEMS FPID may include fabricating a pixel plate and a reflector plate so a Fabry-Perot cavity is defined therebetween.

Fabrication may include producing electrical connections between plates and producing circuitry to control plate voltages to facilitate creating an electrostatic force between plates. The MEMS FPID may include stops fabricated from a conductive material and circuitry for maintaining the stops and plates at an electrical potential that will yield a zero electric field contact event.

Abstract:
Ambient light that is modified for use in a projection system is described. In an embodiment of the present invention, a projection system includes a projection screen and an ambient light source. The projection screen reflects and/or emits one or more ranges of wavelengths of visible light. The projection screen also absorbs visible wavelengths of light in at least one other range that is not included in the one or more ranges. The ambient light source outputs visible wavelengths of light in the at least one other range. The at least one other range of wavelengths have a greater intensity as weighted by the sensitivity of a human eye than that of the wavelengths of light output by the ambient light source in the one or more ranges.
Abstract:
An electronic device of an embodiment of the invention is for at least partially displaying a pixel of a displayable image. The electronic device includes a first reflector and a second reflector that define an optical cavity therebetween, and which is selective of a visible wavelength at an intensity by optical interference. The electronic device also includes a mechanism to allow optical properties of the optical cavity to be varied. The visible wavelength and/or the intensity are thus variably selectable in correspondence with the pixel of the displayable image.

An antireflection surface formed using a plurality of nanostructures of a first material on a surface of a second material. The first material is different from the second material. The distribution of spatial periods of the nanostructures is set by a self-assembly operation. The surface of the second material is converted to operate as a graded index surface that is substantially antireflective for the wavelength of interest.
