The HOPping Field Emission Display (HOPFED) is a new architecture for field emission displays. The main difference between a conventional Field Emission Display (FED) device and a ItOPFED lies in the spacer structure. In a HOPFED, two dielectric plates, named hop and flu spacer, are sandwiched between the emitter and the front plate. The objective of this spacer structure is to improve the performance oF a FED substantially with notable contrast, color purity and luminance uniformity. In order to optimize the structure of the device and to make the electron spot on the screen match the requirement of the phosphor dot dimension, the influence of electrical and structural parameters of the device on the electron spot profile was studied by numerical simulation in this paper. Monte Carlo method was employed to calculate the potential distribution inside hop and flu spacers due to secondary electrons mechanism plays an important role in HOPFED. The results indicated that the potential distribution in the spacers and spot profile depended strongly on the hop voltage, anode voltage and spacer's layout. This study may provide a useful theoretical support for optimizing the structure in HOPFED. 相似文献

The Field Emission Display (FED) is one of the most promising flat panel displays for the future. Currently this has been demonstrated using Very Large Scale Integrated circuit (VLSI) thin film technology to manufacture the key component of the FED, which is the Spindt type molybdenum micro-cone-shape field emitters. These are normally produced on glass or silicon substrates. In this paper, a new approach has been successfully developed to fabricate micro-field emitters on ceramic substrates. The significance of this development is that it provides the possibility to integrate small size FEDs into large dimensions. 相似文献

Carbon nanotubes/nanofibers (CNTs) used as emitters, diode-type field emission display (FED) prototypes of dot matrix and character images were fabricated by low-cost techniques and equipments, respectively. The technical development in the design and fabrication of the cathode, the anode, and the panel, is described. CNTs were produced by a simple, low-cost and easily-controllable thermal chemical vapor deposition. The cathode was prepared by the screen-printing method. The field emission characteristics were enhanced by a heat post-treatment in H2 gas atmosphere. The panel structure was packaged by a vacuum fluorescent display-like process and vacuum-sealed through an exhaust glass tube. The fully-sealed CNTs FED (c-FED) showed good emission properties. The brightness of 600 cd/m2 was achieved from the yellow phosphor at a relatively low applied electric field. The developed technology has a potential practical application in c-FED. 相似文献
