Abstract: The emitter plate 60 of a field emission flat panel display device includes a layer 68 of a resistive material and a mesh-like structure 62 of an electrically conductive material. A conductive plate 78 is also formed on top of resistive coating 68 within the spacing defined by the meshes of conductor 62. Microtip emitters 70, illustratively in the shape of cones, are formed on the upper surface of conductive plate 78. With this configuration, all of the microtip emitters 70 will be at an equal potential by virtue of their electrical connection to conductive plate 78. In one embodiment, a single conductive plate 82 is positioned within each mesh spacing of conductor 80; in another embodiment, four conductive plates 92 are symmetrically positioned within each mesh spacing of conductor 90. Also disclosed is an arrangement of emitter clusters comprising conductive plates 102 having a plurality of microtip emitters 104 formed thereon, or spaced thereform by a thin layer of resistive material, each cluster adjacent and laterally spaced from a stripe conductor 100 by a region 106 of a resistive material. The conductive stripes 100 are substantially parallel to each other, are spaced from one another by two conductive plates 102, and are joined by bus regions 110 outside the active area of the display.

Abstract: 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.
