Title: Low Cost Field Emission Flat Panel Displays Final Report CRADA No. TC-0774-94

Abstract

The ion accelerator at LLNL enabled the fabrication of field emitter cathodes with unique physical attributes not previously avaiIabIe. These properties enabled Candescent to fabricate field emission displays in a low cost, manufacturable manner with cathode performance (efficienq and emission quality) unprecedented in the industry. Candescent and LLNL delivered to ARPA, at the end of the 15 month program, a 3" diagonal black and white display with 80 lines per inch resolution, greater than 20 footlamberts brightness, and at least 16 levels of gray. Additionally, there was a like 3" diagonal color display DOE deliverable. In comparison to liquid crystal displays, the field emission display was brighter, sharper, and consumed 1/3 to 1/2 the power per unit area. The objective of the project was to confirm the efficacy of a new technology (ion tracking) for making efficient, cost effective cathodes for flat panel displays. LLNL was to provide the ion tracking system and experfise and Candescent was to provide the requirements, complete the fabrication of the cathodes, and incorporate them in flat panel displays. The program was quite successful. Candescent is now on the verge of commercializing 5.3 inch diagonal full color flat panel displays using this technology.
