摘要：
A method for producing multi-figure luminescent display tubes comprising a step of baking a frit glass for fixing parts such as grid electrodes and filament supports onto a substrate which is provided with segment electrodes having phosphor layers applied thereon. The baking process is carried out in a non-oxidizing environment and an infrared heater is used prior to baking to eliminate the frit binder.
