Patent Images
1. A vehicle backlit panel comprising:
- a base substrate;
an electroluminescent element disposed on one side of the base substrate; and
an outer substrate overlying the electroluminescent element, the outer substrate including a translucent substrate portion having a planar side surface and a contoured side surface, the translucent substrate portion having a plurality of areas of different thicknesses as measured between the planar side surface and the contoured side surface in a direction of illumination of light from the electroluminescent element through the outer substrate to form a three-dimensional graphic image with a three-dimensional appearance resulting from different translucency levels of the plurality of areas of different thicknesses,with the direction of illumination being generally perpendicular to both the planar side surface and the contoured side surface.

Abstract
A vehicle backlit panel includes a base substrate, an electroluminescent element and an outer substrate. The electroluminescent element is disposed on one side of the base substrate. The outer substrate overlies the electroluminescent element. The outer substrate includes a translucent substrate portion having areas of different thicknesses as measured in a direction of illumination through the outer substrate to form a three-dimensional graphic image with a three-dimensional appearance resulting from different translucency levels of the areas of different thicknesses.

24. A vehicle backlit panel comprising:
-
a base substrate; an electroluminescent element disposed on one side of the base substrate, the electroluminescent element having an electroluminescent material having a generally uniform thickness and a prescribed two dimensional shape; and an outer substrate overlying the electroluminescent element, the outer substrate including a translucent substrate portion having a plurality of areas of different thicknesses as measured in a direction of illumination of light emitted by the electroluminescent element, the areas of different thicknesses being in registration with the prescribed shape of the electroluminescent material such that the plurality of areas of different thicknesses are measured parallel to the direction of illumination.
