    Abstract: A reflective device wherein the device reflectivity is adjustable via automatic or manual means. The variable reflectance element includes a metallic mirror reflector on one side of a substrate and additional substrate layers consisting of a polarizer and a LCD whose material characteristics have been optimized for dimming. The mirror assembly provides alternate trigger mechanisms for initiating the dimming function, the dimming function being automatically referenced to ambient light levels (day or night) or manually adjusted or selected. In the automatic mode the dimming mirror assembly provides the user immediate eye protection from reflected high intensity glare by effecting near instantaneous adjustment in mirror reflectivity, such that the intensity of the reflected light impinging on the eyes is automatically adjusted so as to be at comfortable levels. The mirror assembly construction is in one piece, and allows the viewing of a display or TFT monitor located adjacent to the mirror.

A liquid crystal display includes first and second substrates. A spacer maintains a distance between the first and second glass substrates. A liquid crystal layer is provided between the first and second substrates. A pixel electrode film and a common electrode film are formed over a base insulation film of the first substrate so as to sandwich a pixel insulation film in between. The common electrode film, the pixel electrode film or both of them are partly removed in a region corresponding to the spacer, and the pixel insulation film is partly removed in that region. It prevents the film structure from being broken due to deformation of the base insulation film made of a soft material caused by a pressure applied onto the spacer.

  • Patent number: 7572017
    Abstract: A signal mirror system for a vehicle includes a reflective mirror element comprising a semitransparent nondichroic mirror reflector coated onto a light-transmitting substrate. The visible light transmission through the reflective mirror element is in the range of from about 1% visible light transmission to about 30% visible light transmission and the visible light reflectance is in the range from 40% visible light reflectance to 80% visible light reflectance for visible light incident upon the front side of the reflective mirror element. A turn signal display having at least one light emitting diode is disposed to the rear of the reflective mirror element and configured to emit light that light passes through the semitransparent mirror reflector to be viewed by a viewer viewing from the front of the reflective mirror element with a display luminance of at least about 30 foot lamberts.

  • Patent number: 7543947
    Abstract: A rearview mirror element for a motor vehicle includes a light transmitting substrate having a visible light reflecting and visible light transmitting mirror reflector disposed on a surface thereof. A display-on-demand display device is disposed behind the substrate such that light emitted by the display device when powered passes through both the light transmitting substrate and the mirror reflector. The display device exhibits, when powered during day time driving conditions, a display luminance of at least about 60 foot lamberts. When not emitting light, the disposition of the display device to the rear of the light transmitting substrate is not substantially distinguishable to the driver of the equipped vehicle when viewing the mirror element. To the rear of the light transmitting substrate is rendered substantially opaque by a light absorbing element that is disposed at least adjacent to where, and except at where, the display device is disposed therebehind.

  • Publication number: 20080247046
    Abstract: Proposed is a glare free pan for a rear view service in motor vehicles, possessing a curved transparent substrate, the front surface of which forms the exposed surface of the said mirror. Upon the rear surface of said substrate is applied, in appropriate thicknesses, by sputtering at least four successive and contiguous layers of respectively niobium pentoxide, silicon dioxide, chromium and a protect covering of lacquer. The chromium layer provides the effective reflecting quality of the said mirror. The composition and thicknesses of the layers allows the mirror to reflectively function in visible light wavelengths suitable for both night and day service. Proposed also is a method for the manufacture of the above as well as its assembly into a rear view mirror ready for vehicle installation.

  • Patent number: 7427140
    Abstract: The present invention relates to a sunlight readable computing device, especially, to a full color direct-view and projection-view computing device. When the computing device works in the direct-view mode, the display panel tilt up to the conventional display position and it has a wide, open viewing angle; when the computing device works in the projection view mode, the display panel tilt down and forms a projection image via a mirror plate with a sufficient high contrast ratio and superior readability even directly under sunshine. The solar ambient light can be utilized as the lighting source in both direct-view and projection-view display modes, thus remarkably reduces the power consumption and substantially prolongs the operation time of the computing device.

  • Patent number: 7320525
    Abstract: A rearview mirror reflects ambient light and dims when light from headlights of a following motor vehicle is detected. Electrochromic mirror glass is fixedly secured to a frame within an opening. A sensor is fixedly secured to a housing for sensing ambient light and focused or glare light directed toward the rearview mirror. A light guide is disposed between the housing and the sensor for directing the ambient light and glare light outside the housing toward the sensor. The rearview mirror also includes a switching device for periodically disrupting the transmission of the light to identify a presence of the glare light, such that the sensor creates a dimming signal upon the identification of the presence of the glare light to dim the electrochromic mirror glass. The use of the switching device minimizes the number of sensors required by using the same sensor for measuring ambient light and glare light.
