Abstract
Display panels having at least one suspended fibrous cathode containing an electron field emitter are disclosed. The fibrous cathode is supported by a substrate (10) containing two sets of parallel rows of crests and valleys. The first set of parallel crests (11) and valleys (12) provide the valleys along which the fibrous cathode is aligned. The second set of parallel crests (13) and valleys (14) is perpendicular to the first set. The valleys (14) provide the means for suspending the fibrous cathode. The display panels can be produced in large sizes while still maintaining high quality and efficiency.
