ABSTRACT:
An automotive decorative display panel is devised to provide a reflective black insignia on a bright field during daylight conditions and illuminated insignia on a dark field during night-time conditions. The illuminated display panel is comprised of a lens panel having a reflective, opaque field and a translucent insignia field. A screen is disposed behind the insignia field. The screen is characterized by being partially reflective and partially transmissive. During the day, light is reflected from the screen through the insignia portion to form a black insignia field against the bright reflective field. During the night the screen is back lit to form a bright insignia field against a relatively dark background. A solid state electroluminescent panel is used as the light source in a hermetically sealed package. In addition, the screen is composed of a plurality of line print screens of decreasing line density wherein each screen is rotated with respect to the adjacent screen in order to remove moire patterns.
