Abstract: Described are methods for making, and resultant structures of, a field emission display with soft luminescence and a comfortable image for a viewer of the display. The field emission display is formed with a baseplate and an opposing face plate. Field emission microtips are formed in openings in a conductive and insulating layer on the baseplate. An anode is formed on either the faceplate, or on the conductive layer surrounding each opening. Phosphorescent material is formed over the anode, A blocking layer is formed between the phosphor and the faceplate, such that during operation of the display direct light emission from the phosphor is blocked, resulting in indirect phosphorescence and a more comfortable display image. An optional reflective layer may be added over the conductive layer to increase phosphorescence.

Abstract: A field emission display includes electrostatic discharge protection circuits coupled to an emitter substrate and an extraction grid. In the preferred embodiment, the electrostatic discharge circuit includes diodes reverse biased between grid sections and a first reference potential or between row lines and a second reference potential. The diodes provide a current path to discharge static voltage and thereby prevent a high voltage differential from being maintained between the emitter sets and the extraction grids. The diodes thereby prevent the emitter sets from emitting electrons at a high rate that may damage or destroy the emitter sets. In one embodiment, the diodes are coupled directly between the grid sections and the row lines. In one embodiment, the diodes are formed in an insulative layer carrying the grid sections. In another embodiment, the diodes are integrated into the emitter substrate.

Abstract: A field emitter device formed by a veil process wherein a protective layer comprising a release layer is deposited on the gate electrode layer for the device, with the protective layer overlying the circumscribing peripheral edge of the opening of the gate electrode layer, to protect the edge of the gate electrode layer during etching of the field emitter cavity in the dielectric material layer on a substrate, and during the formation of a field emitter element in the cavity by depositing a field emitter material through the opening. The protective layer is readily removed subsequent to completion of the cavity etching and emitter formation steps, to yield the field emitter device. Also disclosed are various planarizing structures and methods, and current limiter compositions permitting high efficiency emission of electrons from the field emitter elements at low turn-on voltages.

Abstract: In a source for the generation of large-area pulsed ion or electron beams from an anode discharge electrode which has openings receiving discharge electrodes forming a vacuum arc plasma source, the discharge is safely triggered by a load which determines the total current and which consists of a parallel circuit including an ohmic resistor and a capacitor wherein the load output is adapted to the internal resistance of the pulse voltage generator. With a dimensioning of the electrical components taking into consideration given limits, a homogeneous beam of charged particles is obtained wherein the particle composition can be all the same or a homogeneous mixture of different particles depending on the choice of electrode materials.

Abstract: A field emission device (10) is made with a lateral emitter (100) substantially parallel to a substrate (20) and with a simplified anode structure (70). The lateral-emitter field-emission device has a thin-film emitter cathode (100) which has a thickness not exceeding several hundred angstroms and has an emitting blade edge or tip (110) having a small radius of curvature. The anode's top surface is precisely spaced apart from and below the plane of the lateral emitter and receives electrons emitted by field emission from the blade edge or tip of the lateral-emitter cathode, when a suitable bias voltage is applied. The device may be configured as a diode, or as a triode, tetrode, etc. having one or more control electrodes (140) positioned to allow control of current from the emitter to the anode by an electrical signal applied to the control electrode. In a particularly simple embodiment, a single control electrode (140) is positioned in a plane above or below the emitter edge or tip (110) and automatically aligned to that edge. The simplified devices are specially adapted for use in arrays, including field emission display arrays.

Abstract: A cold cathode field emission device is described. A key feature of its design is that groups of microtips share a single conductive disk with a reliable ballast resistor being interposed between each of these conductive disks and the cathode conductor. Additionally, a resistor, rather than a conductor, is used to connect the gate conductive disk to the gate electrode. The latter is arranged so as not to overlap with the cathode electrode. The cathode and gate conductive disks ensure that the ballast resistance asociated with each microtip is essentially the same.
