Abstract:
A vehicular video mirror system includes an interior rearview mirror assembly having a transflective reflective element. The mirror system includes a video display device at a casing of the mirror assembly rearward of the transflective reflective element, with the video display device having a video screen and a plurality of individual white light emitting light sources operable for backlighting the video screen. The intensity of light emitted by the white light emitting light sources is variable responsive to detection of light by at least one photosensor. The video screen may be operable to display video images captured by a rear back-up camera of the equipped vehicle during a reversing maneuver of the equipped vehicle. Light emanating from the white light emitting light emitting diodes may pass through a brightness enhancement film and a light diffuser to be incident at a transflective reflector of a second substrate of the mirror assembly.
Abstract:
There are provided a display that can block light so that a display on an image display device is invisible from a wide range of view angles in an oblique direction, and a view angle control element employed therein. In a narrow view angle state, a view angle control liquid crystal panel (2) prevents light in a predetermined wavelength region that has been incident at a polar angle of φH or more from being transmitted through a polarizing plate (22) by using a phase difference imparted by a liquid crystal cell (21). In the narrow view angle state, a view angle control liquid crystal panel (3) prevents light that has been incident at a polar angle of φL or more, among light that has been transmitted through the polarizing plate (22), from being transmitted through a polarizing plate (32) by using a phase difference imparted by a liquid crystal cell (31). Consequently, light forming a polar angle of φL or more is blocked as a whole, which allows the narrow view angle state to cover a wide range.

Abstract:
A video mirror system for a vehicle comprising an interior rearview mirror assembly having a transflective electro-optic reflective element that transmits at least about ten percent of visible light incident thereon and reflects at least about sixty percent of visible light incident thereon. A display module is disposed at a rear of the transflective electro-optic reflective element and comprises a plurality of individual light sources. A thermally conductive element may be in substantial thermal contact with the display module and is exposed at a rear casing portion of the mirror assembly so as to draw heat generated by the display module away from the display module and to the exterior of the interior rearview mirror assembly. The exposure of the thermally conductive element at the rear casing portion may be substantially not discernible to a viewer viewing the rear casing portion of the interior rearview mirror assembly.
