Abstract

Official abstract text for this publication.

A vehicle projection display system including a transparency, a rearview display, a display aid layer positioned on the transparency and a projector coupled to the rearview display and configured to project light onto the display aid layer. The display aid layer is configured to scatter the light to form a projected image on the display aid layer.

First claim

Opening claim text (preview).

What is claimed is: 1 . A vehicle projection display system, comprising: a transparency; a rearview display; a display aid layer positioned on the transparency; and a projector coupled to the rearview display and configured to project light onto the display aid layer, wherein the display aid layer is configured to scatter the light to form a projected image on the display aid layer. 2 . The vehicle projection display system of claim 1 , wherein the transparency is a windscreen. 3 . The vehicle projection display system of claim 2 , wherein the projector is configured to project the light onto a driver-side portion of the windscreen. 4 . The vehicle projection display system of claim 2 , wherein the projector is configured to project the light onto a passenger-side portion of the windscreen. 5 . The vehicle projection display system of claim 1 , wherein the transparency is a side window. 6 . The vehicle projection display system of claim 1 , further comprising: an orientation sensor configured to detect the orientation of the rearview display within the vehicle. 7 . The vehicle projection display system of claim 6 , wherein the projector is configured to alter a direction of the emitted light in response to the orientation sensor detecting a change in orientation of the rearview display. 8 . A vehicle projection display system, comprising: a transparency; a display aid layer positioned on a surface of the transparency; and a projector positioned to project light onto the display aid layer, wherein the display aid layer is configured to scatter light to form a projected image on the display aid layer. 9 . The vehicle projection display system of claim 8 , wherein the projector is positioned above the transparency in a headliner. 10 . The vehicle projection display system of claim 8 , wherein the projector is positioned below the transparency in a door trim. 11 . The vehicle projection display system of claim 8 , wherein the projector is a laser projector. 12 . The vehicle projection display system of claim 8 , wherein the projector is a digital light processing projector. 13 . The vehicle projection display system of claim 8 , wherein a plurality of display aid layers are positioned on the transparency. 14 . The vehicle projection display system of claim 8 , wherein the display aid comprises a plurality of resonant nanoparticles. 15 . The vehicle projection display system of claim 14 , wherein the resonant nanoparticles comprise at least one of silver, gold, copper, aluminum, lithium and tantalum. 16 . A vehicle projection display system, comprising: a screen; a display aid layer positioned on a surface of the screen, wherein the display aid layer comprises a plurality of resonant nanoparticles; and a projector positioned to project laser light onto the display aid layer, wherein the display aid layer is configured to scatter the laser light to form a projected image on the display aid layer. 17 . The vehicle projection display system of claim 16 , wherein the screen is transparent. 18 . The vehicle projection display system of claim 16 , wherein the screen is translucent. 19 . The vehicle projection display system of claim 16 , wherein the screen is opaque. 20 . The vehicle projection display system of claim 16 , wherein the resonant nanoparticles comprise at least one of silver, gold, copper, aluminum, lithium and tantalum.
