| The invention relates to a method for producing a field emission display (FED) during which the electrodes (5) of the anode structure (4) are fixed on a first substrate (6) and a layer (7) made of a luminescent material covers said electrodes. The electrodes (2) of the cathode structure (1) are fixed on a second substrate (3) and field emitters (19) are placed, at least in sections, on said electrodes (2). The anode structure (4) and the cathode structure (1) are parallelly aligned with one another in an interspaced manner and are interconnected in a gas-tight manner along their lateral edges (11, 14), whereby, before placing the field emitters (19) on the electrodes (2) of the cathode structure (1), the cathode structure (1) and anode structure (4) are interconnected in a gas-tight manner with the exception of at least one gas inlet and one gas outlet opening (16, 17). The field emitters (19) are only produced after the cathode and anode structures (1, 4) are connected in a gas-tight manner by depositing field emitter material onto the electrodes (2) out of a carrier gas that is introduced between the cathode and anode structures (1, 4). | ||||||

A projection system is constructed using a field emission device 10. A single monochrome FED 10 can be used with projection system electronics 40 and lens 20 to create a monochrome picture on screen 30. Alternatively, a single monochrome FED 10 can project the proper image through color wheel 150 to create a color image which is projected by a lens 20 onto a separate surface 30. In yet another embodiment, a first FED 10 which projects a red image, a second FED 10 which projects a green image, and a third FED 10 which projects a blue image, and three clear focusing lenses 20 create a full color image on screen 30. In this configuration, if the three lenses 20 are colored red, green and blue, then the three FEDs 10 need only present the image data for each color in black, grey, and white. The FED projection system could also utilize a color FED 10 and a clear focusing lens 20 to create a full color image on screen 30. This full color FED 10 could create its color image by using red, green, and blue phosphor stripes 90 which are energized by its cathode 80 configured with full pixels or sub pixels 160. In another embodiment the FED projection system provides a three-dimensional display image on screen 30. The use of FED 10 facilitates a projection system which has low power consumption, reliable electronics, consumes less space, and interfaces to multimedia input signals 50. |
