摘要: 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.

摘要: A xerographic printing system is constructed using a field emission device 120 as a modulated light source. Alternatively, a lens 122 may be disposed between the field emission device 120 and the photoreceptor drum surface 106. The field emission device 120 may project a single pixel row, or may project multiple pixel rows which provide gray scale capability. The field emission device 120 may also provide color print capability.

摘要: A dual mode projection system 30 includes a standard field emission device (FED) display panel 44 within a projector base 32. In this way, the light source of a standard overhead projector is replaced by FED panel 44. FED panel 44 is positioned within projector base 32 such that the viewing surface of panel 44 is substantially flush with the top surface of projector base 32. Thus, in a first mode of this dual mode projection system 30, FED panel 44 provides the light source for projecting an image of graphics 48 printed on transparency 46 onto another surface such as a projection screen or wall. FED panel 44 is coupled via connector 36 in projector base 32 and signal cable 38 to host system 40. Host system 40 may comprise the processing unit of a standard notebook computer including a keyboard 42 for data entry. Display information created by the electronics in host system 40 is transmitted through cable 38 to FED display 44. An image 50 created on FED display 44 is projected via lens system 34 onto a large surface such as a screen or wall. The luminescence needed to display image 50 created by FED panel 44 onto a separate surface is provided by the FED panel 44, and no additional light source is required for this projection function. Thus, in the second mode of this dual mode projection system 30, FED panel 44 provides a display of computer-generated images projected onto another surface. The first and second operational modes may be combined to provide a concurrent transparency and computer-generated video display.
