Abstract:
An optical element drive mechanism is used for a projection optical system constructed from a display element and projecting an image in an enlarging manner, and the mechanism vibrates an optical element constructing a part of the system. The optical element drive mechanism has a vibration member (29) for vibrating the optical element while holding the element and an actuator for driving the vibration member (29) to vibrate the optical element. The vibration member (29) has a pair of stationary sections (23), a movable section (25) capable of vibrating relative to the stationary section (23) while holding the optical element, and a pair of hinge sections (22) for connecting the stationary section (23) and the movable section (25). The movable section (25) receives force from the actuator and rotatingly vibrates about the straight line, as the center axis, connecting the centers of the pair of hinge sections (22).

Abstract:
There is provided a system and method for restricting the movement of a television screen. More specifically, in one embodiment, there is provided a display unit (10) comprising a screen (34), and a frame member (10) connected without a bezel to the screen (34), wherein the frame member (10) comprises a first channel (14) configured to receive a bracket (32) and a second channel (12) configured to receive the screen (34).
Abstract:
A micromechanical mirror combined with a photoluminescent screen is able to efficiently use light from the light source. In such a device, the light source produces light that is directed onto the micromechanical mirror. The micromechanical mirror then selectively reflects the light onto a photoluminescent screen. The light excites the photoluminescent screen to produce the desired picture. The photoluminescent screen may include sets of pixels that convert light from the light source to provide the desired picture. Typically, each pixel set includes a red, green and blue portion although any suitable combination of colors and number of pixels may be used. Each pixel set portion converts the light received from the light source into its respective color by photoluminescence. Alternatively, the photoluminescent screen may include transparent and/or scattering portions instead of photoluminescent portions of a certain color when the light source has a spectrum which is limited to one color.

Abstract:
A projection display is described having two structural support arms for mounting the projection display on a stand or on a bracket. A light engine generates a light pattern to be displayed by the projection display. A bridge plate is positioned between the two support arms and the light engine is mounted on the bridge plate.
Abstract:
A portable multimedia projection system (100, 200, 300, 400) includes a portable housing (120, 220, 320, 420), a media player (27), a sound system (32/34/36), an image projection device (22), a controller (90) and a vibration dampening device (50, 60). The sound system (32/34/36) has at least one internally-mounted speaker (32, 34, 36). The image projection device (22) externally projects images. The controller (90) is electrically coupled to the media player (27), the sound system (32/34/36) and the image projection device (22). The controller (90) directs audio signals from the media player (27) to the sound system (32/34/36) and directs video signals from the media player (27) to the image projection device (22). The vibration dampening device (50, 60) is coupled between the housing (120, 220, 320, 420) and at least one of the media player (27), the at least one internally-mounted speaker (32, 34, 36) and the image projection device (22).
