摘要： A compact and efficient optical system featuring planar multi-layered LED light source arrays concentrating their polarized or unpolarized output within a limited angular range. The optical system manipulates light emitted by a planar light emitters such as electrically-interconnected LED chips. Each light emitting region in the array is surrounded by reflecting side-walls whose output is processed by elevated prismatic films, polarization converting films, or both. The optical interaction between light emitters, reflecting sidewalls and the elevated prismatic films create overlapping virtual images between emitting regions that contribute to the greater optical uniformity. Practical illumination applications of such uniform light source arrays include compact LCD of DMD video image projectors, as well as general lighting, automotive lighting, and LCD backlighting.

摘要： A display is provided which includes an interferometric modulator, and a driving circuit (22) coupled to the interferometric modulator. The driving circuit (22) is configured to provide actuation signals to drive the interferometric modulator based on a temperature of the display. A method of driving an array having a plurality of interferometric modulators configured into a display is also provided. According to this method, a temperature at a predetermined location in the display is sensed (102). A sensor signal is communicated (104) to a display driver based on the sensed temperature. A drive signal is generated (106) in the display driver based on the sensor signal and a physical characteristic of an interferometric modulator of the array and is then provided (108) to the interferometric modulator.

摘要： An electromechanical systems device includes a plurality of supports disposed over a substrate and a deformable reflective layer disposed over the plurality of supports. The deformable reflective layer includes a plurality of substantially parallel columns extending in a first direction. Each column has one or more slots extending in a second direction generally perpendicular to the first direction. The slots can be created at boundary edges of sub-portions of the columns so as to partially mechanically separate the sub-portions without electrically disconnecting them. A method of fabricating an electromechanical device includes depositing an electrically conductive deformable reflective layer over a substrate, removing one or more portions of the deformable layer to form a plurality of electrically isolated columns, and forming at least one crosswise slot in at least one of the columns.

摘要： An apparatus and method for updating a display comprising means (12a, 12b) for modulating light, such as interferometric modulators. First and second potential differences having opposite polarity and an approximately equal magnitude sufficient are applied to actuate the modulating means (12a, 12b). The potential differences are applied to the modulating means (12a, 12b) at defined times and for defined time durations that depend on a rate at which image data is written to modulating means (12a, 12b), and are applied for an approximately equal amount of time over a given period of display use.

摘要： Various embodiments of a display device described herein include an optical propagation region (97), at least one optical loss structure (93), an optical isolation layer (95), and a plurality of display elements (91). The propagation region includes a light guide in which light is guided via total internal reflection and turning features configured to redirect the light out of the propagation region. The loss structure would disrupt the total internal reflection of at least some of the light guided within the propagation region if disposed directly adjacent thereto. The optical isolation layer includes a non-gaseous material between the propagation region and the loss structure, and is configured to increase an amount of light that is totally internal reflected in the propagation region. The plurality of display elements are positioned to receive the light redirected out of the propagation region. The loss structure is positioned between the plurality of display elements and the propagation region.
