Parameters for improving reliability of full color field emission display devices

Abstract

Field emission display devices of 100 mmϫ100 mmϫ2.4 mm in size are fully developed with the 80 cd/m 2 of brightness. Full color real images are characterized by using structural analysis and electron trajectory profiles. No cross talk between pixels is confirmed by a simulation and a process integration. As a reliable process integration, phosphor screening integration of full color phosphors and conditions of high vacuum packaging are extensively investigated as a basis of mass production. In addition, the electrical reliability with a phosphor effect due to an electron excitation is studied with a lifetime test at various condition. Especially, the stability inside narrow vacuum space between anode and cathode plates is fully demonstrated with various process control parameters.

Electrophoretic Deposition of Phosphors for Information Displays and Solid State Lighting

“…In another study, process variables to improve the reliability of full color FEDs were investigated [67]. A full color FED panel consisted of pixels of 500 µm × 120 µm, 100 µm, and 120 µm for red (Y 2 O 2 S:Eu), green (ZnS:Cu,Al), and blue (ZnS:Ag,Cl) phosphor, respectively, each electrophoretically deposited.…”
