Abstract
A field emission display panel 20, 80, and 90 is used as a projection system. Display panel 90 can be used as a stand-alone projector. Alternatively, display panel 20 can be placed on a base 10 of a standard overhead projection system 60 and the image can be projected by a lens 50 onto a surface separated from display 20. In yet another embodiment, a lens system 70 can be attached to display panel 80 to project the image on a surface separated from display 80. Display panels 20, 80, and 90 operate at a increased luminance to facilitate projection of the images displayed on the panels. The use of FED display panels 20, 80, and 90 facilitates a projection system which has low power consumption, is portable, and interfaces to a computer.
