Abstract
Abstract Methods of making complex panel structures having precision dimensions. Glass tubes, rods, plates or other large glass structures are redrawn individually or in groups to filamentary or capillary size tube or glass continuums which are assembled as a monolayer to form a gas discharge panel, for example. Complex glass structures having precision uniform cross-sectional dimensions are constructed. Various novel glass structures and/or conductor configurations and methods of assembling are disclosed.
