摘要:
A control system for a variable transmittance optical filter assembly includes a controller in communicatively coupled to a pair of load terminals, and a memory communicatively coupled to the controller and having encoded thereon statements and instructions executable by the controller to transition the optical filter assembly between operating states when coupled to the pair of load terminals. The controller is operable to perform any one or more of: allowing the optical filter assembly to transition to a dark state by shorting the load terminals together, maintaining the optical filter assembly in a hold mode by applying a pulse width modulated voltage signal across the load terminals, and transitioning the optical filter assembly between operative states by applying a voltage signal having voltage pulses of opposite polarities to the load terminals.

A variable reflectance vehicular electro-optic rearview mirror reflective element assembly includes a front substrate and a rear substrate and a perimeter seal disposed therebetween. The front substrate has a first surface and a second surface that has a transparent electrically conductive coating disposed thereat. The rear substrate has a third surface and a fourth surface, with the third surface having a conductive coating disposed thereat. The perimeter seal spaces the front and rear substrates apart and forms an interpane cavity therebetween. The third surface conductive coating includes a plurality of layers, which includes a first layer of nickel chromium. The first layer of nickel chromium is overcoated with a silver or silver alloy layer, and the silver or silver alloy layer is overcoated with a second layer of nickel chromium, and the second layer of nickel chromium is overcoated with a reflective layer.

Electro-wetting display devices are disclosed. The electro-wetting display may include an upper structure and a lower structure opposite to each other, a hydrophobic insulating layer covering a bottom surface of the upper structure, hydrophilic partitions disposed between the hydrophobic insulating layer and the lower structure to define pixel regions, and a colorless conductive fluid and a colored non-conductive fluid filling each of the pixel regions. A specific gravity of the colored non-conductive fluid may be smaller than a specific gravity of the colorless conductive fluid.

Exemplary methods, systems and components enable an enhanced direct-viewing optical device to include customized adjustments that accommodate various optical aberrations of a current user. A real-time adjustment of transformable optical elements is sometimes based on predetermined corrective optical parameters associated with a current user. Customized optical elements are incorporated with the direct-viewing optical device to produce a specified change in optical wavefront at an exit pupil. Possible transformable or replacement optical elements may have refractive and/or reflective and/or diffractive and/or transmissive characteristics that are selected based on current performance viewing factors for a given field of view of the direct-viewing device. Some embodiments enable dynamic repositioning and/or transformation of corrective optical elements responsive to a detected shift of a tracked gaze direction of a current user. Replacement corrective optical elements may be fabricated for current usage or retained in inventory for possible future usage in the direct-viewing device.

This methods and devices described herein relate to displays and methods of manufacturing cold seal fluid-filled displays, including MEMS. The fluid substantially surrounds the moving components of the MEMS display to reduce the effects of stiction and to improve the optical and electromechanical performance of the display. The invention relates to a method for sealing a MEMS display at a lower temperature such that a vapor bubble does not form only at temperatures about 15° C. to about 20° C. below the seal temperature. In some embodiments, the MEMS display apparatus includes a first substrate, a second substrate separated from the first substrate by a gap and supporting an array of light modulators, a fluid substantially filling the gap, a plurality of spacers within the gap, and a sealing material joining the first substrate to the second substrate.
