Apparatus And Method For Displaying Information Within A Vehicle Interior
First Claim
1. An apparatus for displaying information within a vehicle interior, the apparatus comprising:
- a display surface having a coating that is adapted for emitting visible light when said coating is excited by an ultraviolet (UV) light beam having a predetermined wavelength; and
a laser projection device (LPD) operable for generating said UV light beam and for directing said UV light beam onto said coating;
wherein the information is displayed on said display surface when said visible light is emitted by said coating.

Abstract
An apparatus for displaying information within a vehicle interior includes a surface having a coating for emitting visible light when excited by an ultraviolet (UV) light beam, and a laser projection device (LPD) for generating and directing the UV light beam onto the coating to display information on the surface. The LPD generates one or more UV laser beams, and the coating has one or more light-emitting layers each excitable by a different UV wavelength. Each layer emits a different color of light when excited. The surface is a transparent windshield or lens, or an opaque surface. A method for displaying information within a vehicle interior includes applying a light-emitting coating to a surface in at least one layer, and generating and projecting a UV light beam onto the coating to present information in at least as many colors as there are layers.

13. A method for displaying information within a vehicle interior, the method comprising:
-
applying a coating to a display surface of the vehicle interior, said coating being configured for emitting visible light when excited by an ultraviolet (UV) light beam having a predetermined wavelength; generating said UV light beam; and projecting said UV light beam onto said coating to thereby excite said coating to emit said visible, thus causing the information to be displayed on said display surface using said visible light. - View Dependent Claims (14, 15)
