PROBLEM TO BE SOLVED: To provide a method of reducing power consumption in a display device comprising two or more rows of display elements.SOLUTION: A method and system for reducing power consumption in a display includes driving a display comprising a plurality of display elements characterized by a display state. In a first mode of operation, the display state of substantially all the display elements is periodically re-set so as to display a first series of image frames. Upon changing to a second mode of operation, the second mode of operation includes displaying a second series of image frames at a display element resolution which is less than said display element resolution used to display said first series of image frames.

PROBLEM TO BE SOLVED: To provide a device that selectively absorbs and/or reflects light using the principles of optical interference.SOLUTION: Described herein is the use of a diffusion barrier layer between metallic layers in MEMS devices. The diffusion barrier layer prevents mixing of two metals, which may alter desired physical characteristics and complicate processing. In one example, the diffusion barrier layer may be used as part of a movable reflective structure in interferometric modulators.

PROBLEM TO BE SOLVED: To provide a display device where mechanical components in a device, such as a microelectromechanical device, and/or in an interferometric modulator are configured to be insusceptible to damage.SOLUTION: A packaging system for an electronic device includes one or more spacers 730 that prevent or reduce damage to the electronic device arising from contact between the electronic device and a backplate 750. In addition, a packaged electronic device comprising spacers is thinner than a comparable electronic device manufactured without spacers.
Abstract:
PROBLEM TO BE SOLVED: To provide spatial light modulators having an integrated optical correction structure.SOLUTION: In this method or device, light 202 emitted by a remote light source 100 is maintained within a front light plate 200 by total internal reflection until the light 202 contacts a surfaces 204, from which the light is reflected through a substrate 300 and into elements 310. The light plate 200 may comprise a number of grooves 210 that provide surfaces 204 off of which light 202 may be reflected. Advantageously, light 202 may be redirected into the elements 310 in a narrow beam that is substantially perpendicular to a front surface of the substrate 300.
Abstract:
PROBLEM TO BE SOLVED: To provide methods of writing display data to MEMS display elements for minimizing charge buildup and differential aging.SOLUTION: The methods may comprise writing data with opposite polarities, and periodically releasing and/or actuating MEMS elements during a display updating process. Actuating MEMS elements with potential differences higher than those used during normal display data writing may also be utilized. The minimization is achieved by actuating the MEMS display elements with potential differences having a first polarity during a first portion of a display writing process, and with potential differences having the polarity opposite to the first polarity during a second portion of the display writing process.

PROBLEM TO BE SOLVED: To provide a system and a method of illuminating interferometric modulators using backlighting. SOLUTION: An interferometric modulator array device with backlighting is disclosed. The interferometric modulator array device includes a plurality of interferometric modulator elements, wherein each of the interferometric modulator elements includes an optical cavity. The interferometric modulator array includes an optical aperture region, and at least one reflecting element is positioned so as to receive light passing through the optical aperture region and reflect at least a part of the received light to the cavities of the interferometric modulator elements. In some embodiments, the interferometric modulator elements may be separated from each other such that an optical aperture region is formed between the plurality of adjacent interferometric modulator elements.
