  • Patent number: 5134548
    Abstract: A backlight assembly for a liquid crystal display (LCD) supported on a printed circuit board with the pin sockets on either side of an opening in the printed circuit board so that the LCD straddles the opening. The assembly includes a snap-in reflector having a back wall and a plurality of forwardly extending peripheral walls which can be compressed to permit the backlight reflector to be inserted into the opening and released to hold it in position. A lamp in the backlight assembly shines light through the opening and through the LCD. The reflector has an inner surface that is highly reflective and non-specular, so that ambient light rays entering the front of the opening are captured and reflected forwardly back through the liquid crystal display.

  • Patent number: 5098179
    Abstract: A light modifying device for a liquid crystal display mounted on a PC board is provided with a filter and/or reflector of sheet material which is conveniently releasably installed between the liquid crystal display and the PC board to effect alteration of the properties of light passing through the liquid crystal display. Externally originating light which does not pass through the filter is reflected back to help light the LCD. For this purpose the surface of the filter adjacent the LCD includes a coating that is reflective, as well as light transmissive. The device is provided with securement means for holding the filter in place, but facilitating simple installation and removal.
