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.
