Abstract

A point-of-purchase display having a display board with a front surface and a rear surface. A graphical element, having an illuminated element, is disposed on the front surface, and an optical waveguide is positioned to be visible through an opening in the board to provide an illuminated pattern corresponding with the illuminated element.

Claims (19)

1. A display comprising:

a display board comprising a front surface and a rear surface;

a graphical element disposed on the front surface, wherein the graphical element comprises an illuminated element;

one or more openings in the display board that pass from the front surface to the rear surface; and

an optical waveguide positioned to be visible through the one or more openings, the optical waveguide being capable of redirecting ambient light from a source external to the display to provide an illuminated pattern, corresponding to the illuminated element.

2. The display of claim 1 wherein the illuminated element represents a projected laser beam.

3. The display of claim 1 wherein the illuminated element represents a laser beam.

4. The display of claim 1 wherein a substantial portion of the waveguide extends beyond the rear surface.

5. The display of claim 1 wherein at least a portion of the waveguide extends from the rear surface to the front surface and is approximately flush with the front surface.

6. The display of claim 1 wherein the waveguide is illuminated using natural or ambient light.

7. The display of claim 1 wherein the waveguide is an acrylic or polycarbonate sheet.

8. The display of claim 1 wherein the illuminated pattern corresponds to a size and location of the illuminated element.

9. The display of claim 1 wherein the device depicted by the graphical element is a power tool.

10. A display comprising:

a display board comprising a front surface and a rear surface;

a graphical element disposed on the front surface, wherein the graphical element represents a laser tool;

an opening in the display board that passes from the front surface to the rear surface;

an optical waveguide, having at least one illuminating edge, wherein the optical waveguide is positioned so that the at least one illuminating edge is visible through the opening; and

wherein the optical waveguide is further adapted to receive ambient light from a source external to the display, and emit the ambient light through the at least one illuminating edge to represent a projected laser beam, a laser beam, or a light source associated with a power tool.
