Triode type or diode type cathode structure for use in field emission flat panel display, has slots dimensioned to subsist isolating layer`s zone that is not covered by gate electrode, and resistive layer covered by gate conductors

摘要

#CMT# #/CMT# The structure has an electrical isolating layer (24) and an gate electrode (25) that comprise slots which are dimensioned to subsist the electrical isolating layer`s zone that is not covered by the gate electrode. A width of the slot in the electrical isolating layer has a dimension that is restrained for guiding carbon nanotudes (28) in a direction perpendicular to a support (21). A resistive layer (31) partially covers the gate electrode, and is covered by gate conductors. #CMT#USE : #/CMT# Used in a field emission flat panel display (claimed). #CMT#ADVANTAGE : #/CMT# The cathode structure permits to optimize the leakage current. The resistive layer is covered by gate conductors, thus reducing the power consumption of the display with respect to the structure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a cathode structure. 21 : Support 24 : Electrical isolating layer 25 : Gate electrode 28 : Carbon nanotudes 31 : Resistive layer.
