  • Patent number: 6137213
    Abstract: A field emission device (100, 150) includes a cathode plate (102, 180) having electron emitters (116), an anode plate (104, 170) having a phosphor (107, 207, 307, 407) activated by electrons (119) emitted by electron emitters (116), and a vacuum bridge focusing structure (118, 158, 218, 318) for focusing electrons (119) emitted by electron emitters (116). Vacuum bridge focusing structure (118, 158, 218, 318) has landings (121, 122, 221, 322), which are attached to cathode plate (102, 180), and further has bridges (120, 220, 320), which extend above and beyond landings (121, 122, 221, 322, 421) to provide a self-supporting structure that is spaced apart from cathode plate (102, 180).

  • Patent number: 5727977
    Abstract: A process for manufacturing of a field emission device (100, 200) including the steps of i) providing a substrate (101, 201), ii) forming a conductive row (106, 206), ii) forming a dielectric layer (102, 202), iv) forming a resist layer (116, 216), v) forming a self-assembled monolayer (112, 212) of a self-assembled monolayer-forming molecular species on the resist layer (116, 216) so that the self-assembled monolayer (112, 212) defines an etch pattern for an emitter well (107, 207), vi) etching the resist layer (116, 216), vii) etching the dielectric layer ((102, 202), viii) forming conductive column (103, 203), and ix) forming the electron-emitter structure (105, 208) within the emitter well (107, 207).

  • Patent number: 5726529
    Abstract: A spacer (200) for a field emission display (201) is disclosed. The spacer (200) includes a lower resistive region (220) and an upper insulative region (222). The spacer (200) has a member (210) which is coated with a resistive coating (212) extending between the lower end of the member and a height (h.sub.2) less than the total height (h.sub.1) of the spacer (200). An insulative coating (218) is formed on the member (210) and extends between the upper end of the resistive coating (212) and the upper end of the member (210). The resistive coating (212) has a secondary electron yield less than 2 over the lower resistive region (220) of the spacer (200). The insulative coating (218) has a secondary electron yield between 0.75-2 over the upper insulative region (222) of the spacer (200).

  • Patent number: 5698941
    Abstract: An optical correction layer for a light emitting apparatus having gaps in brightness at the light-emitting surface. The optical correction layer includes a plurality of optical correction regions centered over the gaps, and a plurality of optically transparent regions which overlay the remainder of the light-emitting surface. The optical correction regions include appropriately formed grooves which collect and redirect light adjacent the gap. The light is redirected to cover and effectively conceal the gap. The optically transparent regions permit light to travel through, without redirection.

  • Patent number: 5669303
    Abstract: An apparatus (100) including a support structure (104), a flexible stamp (106) having a stamping surface (110) including a predetermined pattern disposed opposite the support structure (104), a pressure controlled chamber (112) disposed above the support structure (104), and a mechanical attachment (114) affixed to the flexible stamp (106).
