Abstract
A rotating display, particularly for use as a point of purchase inducement to customers in a retail environment, includes a two-sided display panel with fluorescent printed indicia or graphics on at least one side which are illuminated by ultraviolet light. The panel is rotated about its central longitudinal axis at a rotational velocity of at least approximately 300 RPM. The spinning fluorescent indicia, when illuminated in this fashion, create the illusion of a solid through the persistence of vision.
Claims20
A display for creating a persistence-of-vision illusion comprising:
- a panel having first and second sides and a central longitudinal vertical axis passing along a length of said panel between said first and second sides;
- a first fluorescent pattern disposed on said first side of said panel;
- an ultraviolet light for illuminating said fluorescent pattern;
- and
- a drive mechanism for rotating said panel about said central axis at a speed of at least 300 revolutions per minute;
- whereby when the display is rotated at a speed of at least 300 revolutions per minute the pattern appears to be hanging motionless and may be viewed from all sides.
A method for creating a persistence-of-vision illusion in a display comprising the steps of:
- providing a panel having first and second sides, a central longitudinal vertical axis passing along a length of said panel between said first and second sides, and a first fluorescent pattern on one of said sides;
- illuminating said fluorescent pattern with ultraviolet light;
- and
- rotating said panel about said central axis at a speed of at least 300 revolutions per minute to generate said persistence-of-vision illusion;
- whereby when the display is rotated at a speed of at least 300 revolutions per minute the pattern appears to be hanging motionless and may be viewed from all sides.
