Abstract
Rib structures for containing plasma in electronic displays are formed by redrawing glass preform into fiber-like rib components. The rib components are then assembled to form rib/channel structures suitable for use in flat panel displays, such as plasma emissive displays, field emissive displays and plasma addressed liquid crystal displays.
