摘要： Disclosed are a display system and a method of producing the same. In the present invention, a hexagonal pyramid shaped GaN semiconductor light-emitting device selectively crystal-grown is fixed on an upper surface of a substrate by embedding it in an insulation layer formed of an epoxy resin. Then the insulation layer is selectively dry etched in an oxygen plasma atmosphere to expose an upper end portion of the GaN semiconductor light-emitting device. A conductor film is formed on the entire surface, and a required portion of the conductor film is left as a lead-out electrode while the unrequired portion is removed by lithography.

摘要： This disclosure is directed toward field emission surfaces, and is more particularly directed toward improvements in cold, low field, high current, low noise field emission devices and surfaces. Such devices are used in field emission display devices such as video displays and information displays. The device utilizes a cermet with graded concentration of insulative and conductive particles deposited on the truncated point of a conical emitter. The emission surface of the cermet is insensitive to gases that oxidize or poison the emission surface. Such gases and other contaminants emanate from a phosphor when the emission device is used in phosphor display devices. The field emission device is operated at lower potentials thereby reducing power requirements and minimizing heat dissipation requirements. Further, the field emission device which operates at lower field in order to reduce mechanically and temporally unstable emission sites which result in current bursts and current deficits at these sites. Still further, the field emission device incorporates internal resistors which provide series resistance to limit noise at affected emission areas thereby eliminating the need to limit noise by incorporating high-valued resistors, typically in series with the cathode terminal of the emission device, which reduce the potential to the entire emission surface and increasing potentials required to produce current sufficient to excite display phosphor.

摘要： A cathode arrangement for emitting electrons includes an electrode-conductive emission body that defines an emission surface from which the electrons propagate. A slit pattern is cut into the emission body for dividing the emission body into a current path. Two spaced apart conductive terminals on the emission body connect opposite ends of the current path for carrying current along the emission body that is used to heat the emission body by Joule heat.

摘要： A device is disclosed which produces high current, low noise, low lateral energy, stochastic electron emission from a multiplicity of insulative particles subjected to a field. The insulative particles are in and of a surface thickness comprised of a random mixture of insulative and conductive particles in ohmic contact. Emission is achieved at applied potentials of about 5 volts which produce a field sufficient to emit electron currents of nanoamperes to milliamperes. Single devices or arrays of devices may be batch fabricated. Each device has an imtegral, implicity self-aligned electron optic system comprising means for modulating, focusing and deflecting the formed current beam, and means shielding the device from ambient magnetic fields.
