| 20100039370 | METHOD OF MAKING A LIGHT MODULATING DISPLAY DEVICE AND ASSOCIATED TRANSISTOR CIRCUITRY AND STRUCTURES THEREOF - An Interferometric Modulator (IMod) is a microelectromechanical device for modulating light using interference. The colors of these devices may be determined in a spatial fashion, and their inherent color shift may be compensated for using several optical compensation mechanisms. Brightness, addressing, and driving of IMods may be accomplished in a variety of ways with appropriate packaging, and peripheral electronics which can be attached and/or fabricated using one of many techniques. The devices may be used in both embedded and directly perceived applications, the latter providing multiple viewing modes as well as a multitude of product concepts ranging in size from microscopic to architectural in scope. | 02-18-2010 |
| 20110095973 | INTERFEROMETRIC MODULATOR ARRAY WITH INTEGRATED MEMS ELECTRICAL SWITCHES - An iterferometric modulator array is integrated with collapsible cavity MEMS electrical switches. The electrical switches may have similar physical geometry as the display elements. The switches may form row or column select functions for the display. | 04-28-2011 |
| 20110148751 | METHOD AND DEVICE FOR MANIPULATING COLOR IN A DISPLAY - A method and device for manipulating color in a display is disclosed. In one embodiment, a display comprises interferometric display elements formed to have spectral responses that produce white light. In one embodiment, the produced white light is characterized by a standardized white point. | 06-23-2011 |
| 20110169724 | INTERFEROMETRIC PIXEL WITH PATTERNED MECHANICAL LAYER - Interferometric modulators and methods of making the same are disclosed. In one embodiment, an interferometric display includes a sub-pixel having a membrane layer with a void formed therein. The void can be configured to increase the flexibility of the membrane layer. The sub-pixel can further include an optical mask configured to hide the void from a viewer. In another embodiment, an interferometric display can include at least two movable reflectors wherein each movable reflector has a different stiffness but each movable reflector has substantially the same effective coefficient of thermal expansion. | 07-14-2011 |
| 20110193770 | DEVICE AND METHOD FOR WAVELENGTH FILTERING - Embodiments include devices and methods for wavelength filtering. For example, one embodiment includes a display comprising a plurality of the display elements each comprising a movable reflector, a first partial reflector, and a second partial reflector. The first partial reflector is positioned at a first distance from the movable reflector and forms a first optical resonant cavity therebetween. The second partial reflector is positioned at a second distance from said first partial reflector and forming a second optical resonant cavity therebetween. In various embodiments, the movable reflector is movable with respect to the first partial reflector to alter the first optical cavity. Other embodiments include a method of making devices. | 08-11-2011 |
| 20120256819 | INTERFEROMETRIC MODULATOR ARRAY WITH INTEGRATED MEMS ELECTRICAL SWITCHES - An array of display elements, such as interferometric modulators, is integrated with collapsible cavity microelectromechanical system (MEMS) electrical switches. The electrical switches and the display elements may be at least partially formed with the same manufacturing operations. The switches may form row or column select functions for the display elements. | 10-11-2012 |
| 20130063335 | METHOD AND SYSTEM FOR WRITING DATA TO MEMS DISPLAY ELEMENTS - Charge balanced display data writing methods use write and hold cycles of opposite polarity during selected frame update periods. The transitions between voltages of opposite polarity are sufficiently brief that the display elements do not change state. A release cycle may be provided to reduce the chance that a given display element will become stuck in an actuated state. | 03-14-2013 |
| 345109000 | Having shutters | 3 |
| 20080303781 | Shutter Device For Pixel Element and Pixel Arrangement - A micro electromechanical shutter device and a pixel arrangement in which respective shutter elements are configured to controllably take a first geometrical state open and a second geometrical state closed by different degrees of actuation, and wherein the first geometrical state of the shutter element is configured to correspond to a non-actuated rest state of the shutter element. | 12-11-2008 |
| 20090002313 | Lighting apparatus and projection type display, and driving method therefor - A lighting apparatus used for a projection type display is provided, which can change the incident ray volume to an optical modulation device without changing the optical output intensity of the lamp, and can exhibit excellent effects in expressive power of an image and adaptability to the use environment. The lighting apparatus of the present invention comprises; a light source, two fly-eye lenses constituting a uniform lighting device, and a shading plate arranged between these fly-eye lenses and constituting a dimming device for adjusting the amount of light of the outgoing light from the light source. The angle of inclination of the shading plate is controlled based on an image signal supplied to the optical modulation device, thereby enabling adjustment of the amount of light. | 01-01-2009 |
| 20140266999 | MULTI-STATE SHUTTER ASSEMBLY FOR USE IN AN ELECTRONIC DISPLAY - This disclosure provides systems, methods and apparatus for a multi-state shutter assembly. The multi-state shutter assembly can be used in an electronic display. The shutter assembly can include a movable light obstructing component. The shutter assembly also can include first and second actuators configured to move the light obstructing component between three states, including a fully light obstructive state, a substantially transmissive state, and a partially transmissive state. At least one of the three states is a neutral state in which both the first and second actuators are in an unactuated state. The shutter assembly also can include a controller configured to control the first and second actuator to selectively move the light obstructing component into each of the three states. | 09-18-2014 |
