Abstract:
PROBLEM TO BE SOLVED: To provide a MEMS-based display device.SOLUTION: The MEMS-based display device is described, wherein an array of interferometric modulators are configured to reflect light through a transparent substrate. The transparent substrate attached to a back plate via a seal and the back plate can contain electronic circuitry for controlling the array of interferometric modulators. The back plate can be a physical support for device components (for example, electronic components etc.) which can be used to control the state of the display. The back plate can also be utilized as a primary structural support for the device.
Abstract:
PROBLEM TO BE SOLVED: To provide an interferometric modulator in which a higher bit depth is available with fewer pin outs. SOLUTION: A light modulator is arranged as an array of rows and columns of interferometric display elements 40. Each element is divided into sub-rows of sub-elements 42, 44, 46. Array connection lines transmit operating signals to the display elements, with one connection line corresponding to one row of display elements in the array. Sub-array connection lines electrically connect to each array connection line. Switches 56, 58 transmit the operating signals from each array connection line to the sub-rows to effect gray scale modulation. COPYRIGHT: (C)2011,JPO&INPIT

The electronic circuit 114 electrically communicates with the array 102 of the interferometric modulator and is configured to control a status of the array 102 of the interferometric modulator.
Abstract:
PROBLEM TO BE SOLVED: To provide an analog interferometric modulator device with electrostatic actuation and release.SOLUTION: A microelectromechanical system (MEMS) device includes a first electrode, a second electrode electrically insulated from the first electrode, and a third electrode electrically insulated from the first electrode and the second electrode. The MEMS device also includes a support structure which separates the first electrode from the second electrode and a reflective element located and movable between a first position and a second position. The reflective element is in contact with a portion of the device when in the first position and is not in contact with the portion of the device when in the second position. An adhesive force is generated between the reflective element and the portion when the reflective element is in the first position. Voltages applied to the first electrode, the second electrode, and the third electrode at least partially reduce or counteract the adhesive force.
