Patent ID: 7535524

Claim:
A display system, comprising: a display panel operably connected to a control interface configured to provide control signals thereto defining at least one primary image and at least one secondary image for projection from the display panel; a wavelength converting material that absorbs light of a first wavelength and emits light of a second wavelength, the wavelength converting material defining the secondary image when the wavelength converting material is illuminated by the light of the first wavelength, the wavelength converting material being substantially transparent to light of a third wavelength; a first light source configured to cause the wavelength converting material to be illuminated by the light of the first wavelength and project the secondary image from the display panel; a second light source configured to illuminate at least portions of the display panel and cause the display panel to project the primary image therefrom; wherein the first, second and third wavelengths are different from one another, and the control interface is configured to switchably control independent projection or non-projection of the primary and secondary images from the display panel.
