Hopping-Electron Transport in a Field-Emission Display

摘要

Field-emission displays (FEDs) have been discussed for almost 20 years, and substantial efforts have been made in the last decade to begin production of these displays. Those efforts have not yet led to successful market introductions. This lack of success has led some to conclude that the "failing" product is better suited to a museum of oddities than to serving actual market needs. Actually, the opposite is true. We estimate that in 2003 $100 million was spent worldwide on FED research and development, and, at the SID International Symposium and other conferences, many FED-related R&D projects are presented and continue to attract a lot of attention. This continuing interest shows that despite the dominance of liquid-crystal displays (LCDs) and plasma-display panels (PDPs) in the world of flat-panel-display (FPD) technologies, many believe in the commercial viability of FEDs.
