ABSTRACT:
A graphic display is provided which is suitable for use in an instrument panel of an automobile. The graphic display includes a display lens and a number of backlit buttons which are formed by a unitary optically-conductive member, wherein both the display lens and the backlit buttons are illuminated by a single illuminated display located behind the unitary member. As such, the unitary member eliminates the requirement for a separately formed lens and buttons. Furthermore, the illuminated display generates graphics for both the display lens and the buttons, eliminating the requirement for insignia formed in the surface of the buttons and lights or light pipes behind the buttons for backlighting the buttons.
