The structure may comprise a spacer structure between the parallel plates along the outer perimeter of the plates. The spacer structure may include a conductive member. The conductive member may shunt anode to cathode flashovers to a sink outside of the array before they reach the cathode. The conductive member may be provided by a conductive frit made of a metal/glass mixture, a metal foil, or a metal coating that extends through or next to the spacer structure.

A field emitter device including an insulator structure provided on an upper gate line layer of the device. The insulator structure may surround groups of emitters arranged on adjacent gate lines, groups of emitters arranged on the same gate lines, and/or entire regions of a larger array of field emitters. The insulator structure may reduce the occurrence of flashovers to and from the gate lines and emitters when the field emitter device is used in a display. The insulator structure may also enhance the focus of electrons emitted by the field emitter device on the display screen. Focus may be further enhanced by the addition of a resistive coating on the insulator structure. Methods of making the insulator structure and resistive coating are also disclosed.

摘要:
A visible light spectrum and light source apparatus are described that provide over 90% of their total radiant power within the 385 nm-530 nm and the 570 nm-820 nm spectral ranges, collectively. The objective of the light spectrum and apparatus is to improve the visibility and shape of a wider range of objects than is practical using conventional LED white light sources at similar radiant power conditions. The new light source can provide good Scotopic or Mesopic at low power levels compared to most other light sources for illumination. One illustrative embodiment of this new spectrum and light source provides a full visible light spectrum with at least 6% of the highest peak radiant power of all wavelengths between 405 nm-730 nm, and another illustrative embodiment provides a similar full spectrum between 440 nm and 730 nm. In both embodiments, the average radiant power in the 475-510 nm cyan spectral region is at least 2-times the average radiant power in the 530-570 nm spectral region.

摘要:
A structure to reduce the likelihood of flashover in a parallel plate electron beam array is disclosed. The structure may comprise a means for generating a low intensity electric field in the vicinity of a spacer separating the parallel plates of the array, and the anode. The presence of the electric field in the vicinity of the spacer is not conducive to the occurrence of a surface supported flashover on the gates and emitters. The electric field means may be provided by a conductive coating on one or more surfaces of the spacer. Alternatively, the electric field means may be provided by a conductive coating on a guard ring located within the array in the vicinity of the spacer. Methods of making the structure are also disclosed.
摘要:
A high performance novel electron emitter material for use in field emission devices is disclosed. The high performance electron emitter material of the invention may comprise a high Cr and SiO mixture. This material may be formed into high aspect ratio, low work function tips which maintain their shape, thus minimizing flash over risks and electron scattering problems, while at the same time permitting a high level of fabrication process flexibility, and minimizing film stresses. One or more impurities which are conductive oxides or will form conductive oxides may be added to the Cr--SiO composition so that a net low work function emitter may be maintained under oxidation. A class of semi-conductive and conductive metal oxides comprises another embodiment of the invention. These materials include oxides of Cr, Mo, Ni, Fe, and Sc, which have current emitting properties desirable for applications where improved electron emission infirmity is desired among emitters within a pixel. Emission from these more resistive emitter tip materials may be optionally enhanced with the addition of low work function impurities such as alkali metals enabling more stable devices while still permitting low turn-on voltages. Methods of making the emitter are also disclosed.
