Abstract

A non-black dead front display assembly is provided which includes a first plastic layer which in the absence of backlighting is opaque to a viewer, a transparent structural plastic layer, a mask layer with light transparent windows defining at least one graphic, and a support component for supporting a light source for backlighting.

Claims

1. A non-black dead front display assembly comprising:

a first plastic layer having outer and inner surfaces, the first plastic layer in an absence of backlighting being opaque to a viewer resultant from diffused reflective light from the outer surface;

a transparent structural plastic layer having a fiat and second surface the first surface contacting the inner surface of the first plastic layer;

a mask layer with an array of light transparent windows defining at least one graphic and having a front and a rear side, the front side contacting the second surface of the structural plastic layer; and

a support component comprising a light source for backlighting, the support component arranged behind the rear side of the mask layer.

2. The display assembly according to claim 1 wherein the graphic is selected from the group consisting of a symbol, a numeral, an alphabet letter, a word and combinations thereof.

3. The display assembly according to claim 1 wherein the support component is a printed circuit board supporting a plurality of light emitting diodes.

4. The display assembly according to claim 3 wherein the printed circuit board further comprises data storage elements controlling electrical energy levels delivered to the light emitting diodes.

5. The display assembly according to claim 1 wherein the first plastic layer has a smaller cross-sectional thickness than that of the transparent structural plastic layer.

6. The display assembly according to claim 1 wherein the transparent structural plastic layer is formed of polycarbonate.

7. The display assembly according to claim 1 wherein the light source is a liquid crystal display.

8. The display assembly according to claim 1 wherein the transparent structural plastic layer has a cross-sectional thickness ranging from 0.3 to 20 mm.

9. The display assembly according to claim 1 wherein the first plastic layer has a cross-sectional thickness ranging from 3 to 10 mil.

10. The display assembly according to claim 1 wherein the support component is a printed circuit board supporting a plurality of quantum dots to emit light.
