Abstract: An electron-emitting device manufacturing method includes a first step of forming a conductive film on an insulating layer having an upper surface and a side surface connected to the upper surface via a corner portion so as to extend from the side surface to the upper surface and cover at least a part of the corner portion, and a second step of etching the conductive film in a film thickness direction. At the first step, the conductive film is formed so that film density of the conductive film on the side surface of the insulating layer becomes the same as or higher than film density of the conductive film on the upper portion of the insulating film.

Abstract: In an electron beam device employing an electron-emitting device in which a gate and a cathode are provided to sandwich a recess portion formed on an insulating member, electrons are scattered after the collision against the gate and then extracted, it is made possible to easily obtain stable electron emission characteristics and also to prevent the electron-emitting device from being deteriorated or being fractured due to overheating even when an excessive heat has been generated. The electron-emitting device includes the cathode having a protrusion 30 positioned astride the outer surface of the insulating member and the inner surface of the recess portion formed in the insulating member, and the gate including a layered structure of at least two electroconductive layers. A thermal expansion coefficient of the electroconductive layer which is arranged at a part facing to the protrusion is larger than that of the other electroconductive layer.

Abstract: A method of operating and process for fabricating an electron source. A conductive rod is covered by an insulating layer, by dipping the rod in an insulation solution, for example. The rod is then covered by a field emitter material to form a layered conductive rod. The rod may also be covered by a second insulating material. Next, the materials are removed from the end of the rod and the insulating layers are recessed with respect to the field emitter layer so that a gap is present between the field emitter layer and the rod. The layered rod may be operated as an electron source within a vacuum tube by applying a positive bias to the rod with respect to the field emitter material and applying a higher positive bias to an anode opposite the rod in the tube. Electrons will accelerate to the charged anode and generate soft X-rays.

Abstract: The present invention relates to a display device that employs edge emitters as a source for pixel electrons. The edge emitters allow the viewing glass plate to be made very small or eliminated, thereby substantially reducing the size of or eliminating the spacers typically utilized in conventional display devices and thereby enabling a simple and compact assembly structure. In one embodiment a pixel configuration comprises a phosphor area disposed between a plurality edge emitters, each of which are associated with tynes that are adapted to reduce the distance between the emitters and that separate the phosphor area into segments such that the emitters emit electrons when the voltage between a phosphor segment and the an emitter exceed a threshold voltage to cause the phosphor segment to emit light.

Abstract: A field emission element has a gate electrode stacked on a substrate, an emitter electrode stacked on the gate electrode via an interlayer insulating layer, and an anode electrode formed on another substrate facing the emitter electrode. Further, the field emission element includes an anode pixel formed by the anode electrode and a generally rectangular fluorescent body formed thereon and a plurality of wells, each being formed in the emitter electrode and the interlayer insulating layer in a form of a narrow elongated hole. Here, the wells are disposed within a generally rectangular electron emitting area and at least a majority of the wells are arranged parallel to each other, and a length direction of the majority of the wells is substantially normal to that of the fluorescent body and the electron emitting area.

In the FED system disclosed, each pixel elements is composed of at least one edge emitter that is operable to emit electrons and at least one reflector that is operable to first attract and then reflect the emitted electrons onto a transparent layer that is operable to attract the reflected electrons. The transparent anode layer is oppositely positioned with respect to the cathode or emitter edge. In a one aspect of the invention, a phosphor layer interposed between the transparent layer and the pixel element produces a light photon as reflected electrons are attracted to the transparent layer. In another aspect of the invention, a plurality of phosphor layers are applied to the transparent layer to produce a color display when reflected electrons are attracted to the transparent layer.
