A field emission device (100, 200) includes a cathode plate (102) having a plurality of electron emitters (532), an anode plate (104) disposed to receive electrons emitted by plurality of electron emitters (532), a frame (109) interposed between cathode plate (102) and anode plate (104) and defining a central opening (112), a mating member (110, 210, 310, 410, 510) coextensive with frame (109) and disposed within central opening (112), and a getter structure (114, 214, 314, 414, 514, 614) mated with mating member (110, 210, 310, 410, 510).

Field emission device having component capture frame

A method for in situ cleaning of electron emitters (126, 226, 326, 526) in a field emission device (100, 200, 300, 400, 500) includes the steps of controllably providing hydrogen gas (142, 242, 342, 542) within the field emission device (100, 200, 300, 400, 500) at a time during the operational life of the field emission device (100, 200, 300, 400, 500) and, thereafter, emitting electrons from the electron emitters (126, 226, 326, 526), thereby forming hydrogen free radicals, which decontaminate and condition the emissive surfaces of the electron emitters (126, 226, 326, 526).

Method for in situ cleaning of electron emitters in a field emission

A field emission display (200) includes a cathode plate (202); a substrate (102) opposing the cathode plate (202); a conductive matrix (104) disposed on the substrate (102) and having via walls (103) defining a plurality of phosphor vias (105); a phosphor (106, 108, 110) disposed within each of the phosphor vias (105); and a gas-adsorption material distributed within the conductive matrix (104). A method for fabricating the field emission display (200) includes the steps of silk-screening onto the substrate (102) a screenable suspension, which is made from a glass, a metal, a gas-adsorption material, and a photo-sensitive material, to form a film; photo-patterning the film to form a phosphor via (105); depositing a phosphor material into the phosphor via (105) to form an anode plate (100); and affixing the cathode plate (202) to the anode plate (100).

Node plate for field emission display

A field emission device (100, 200) includes a cathode plate (110, 210), an anode plate (112, 212) spaced from the cathode plate (110, 210) to define an interspace region (114, 214) therebetween, a hole (144, 244) defined by the device package and in communication with the interspace region (114, 214), and a hydrogen-selective membrane (140, 240) disposed in registration with the hole (144, 244).

Field emission device having means for in situ feeding of hydrogen

An improved resolution electron gun for a cathode ray tube(CRT) is provided having a cathode, a control grid and an anode. A positive voltage is applied to the anode for the purpose of drawing the electron beam from the cathod, which emits the electron beam along its principal axis. The control grid between the cathode and the anode has a modulating drive voltage to modulate the emitted beam. The anode and the grid are aligned along the principal axis of the cathode and are adjacent to one another. A limiting aperture is mounted along the principal axis to clip the beam and reduce its diameter. A screen is provided along the principal axis within the CRT to receive the projected beam. To obtain increased resolution, the modulating drive voltage is increased while the aperture size is decreased. More specifically, the modulating drive voltage is increased beyond 25% of a predetermined maximum cutoff value, and the limiting aperture permits less than 50% of beam current to transmit.
