Title:
FIELD EMISSION BACKLIGHT FOR LIQUID CRYSTAL TELEVISIONS
Document Type and Number:
WIPO Patent Application WO2006032950
Kind Code:
A3
Abstract:
A field emission device for use as a backlight of a liquid crystal display comprises a conductive anode having a light-emitting layer and a cathode separated from the anode by a spacer. The cathode comprises nanofiber electron emitters. For example, the nanofiber electron emitters comprise a substrate, a conductive film adhered to the substrate and a plurality of isolated, hemispheroidal nanofiber clusters that are capable of emitting electrons at high current density and low field strength.
