Abstract:
A method is disclosed for the fabrication of a gas panel which includes depositing parallel lines as electrical conductors on a pair of glass plates, providing a protective coating of glass over the parallel lines, placing a sealing material between the glass plates around the periphery thereof, spacing the glass plates a given distance apart, firing the assembly in an oven to seal the glass plates together with a chamber therebetween, evacuating the chamber, filling it with an illuminable gas, and exposing each parallel lines at one end of each glass plate as an electrical contact.
Abstract:
Thin parallel electrical conductors are protected from attack during elevated temperature operations in gas panel fabrications by a method which involves depositing the parallel electrical conductors on a pair of glass plates with the parallel conductors terminating a given distance from the edges of each glass plate whereby each such plate extends beyond the ends of the parallel conductors, and covering the parallel conductors with a protective glass coating which covers completely the top, sides, and ends of each parallel conductor. Since the ends of the parallel conductors are covered completely, they are protected from attack and destruction during subsequent firing operations in the fabrication of a gas panel. After panel fabrication is completed one end of each glass plate may be cut off flush with the ends of the parallel conductors if desired. The protective glass coating is removed around the end or terminal regions of the parallel conductors whereby the exposed portions of the conductors may serve as electrical contacts.
