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.

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 a capacitor plate that facilitates electrostatically moving the pixel plate. 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.
摘要:
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.
