Status and Accomplishments
Joint PTCOE/SI Diamond study resulted in breakthrough on low-voltage phosphor performance - this advance considerably lessens the risks in manufacturing low-voltage FED flat panel displays.
System operational requirements for FED phosphors comprehensively defined to give phosphor specifications for manufacturing.
Change injection layer in EL devices shown to give a 20% increased brightness at 20V lower threshold voltage.
New characterization techniques and modeling of TFELs have identified paths for device improvement.
Zn addition to blue thiogallate phosphor increases brightness and lowers threshold voltage (15-30% improvement).
Identified new EL material structures that promise very low-voltage EL devices.
Identified high quantum efficiency R,G,B phosphors for plasma display.
Optimized green phosphor for plasma displays.
University/Industry/National Lab network formed.
Student-Industry exchange program is in its third year.
