Abstract
Abstract There is disclosed a gas discharge display and memory panel having parallel row and parallel column conductor arrays carried on support plates in which both ends of the conductors in the arrays are connected to selection and addressing circuitry so that, in effect, the conductors are made a part of the selection and addressing circuitry. In one embodiment, a dielectric coating on the conductors in the active area of the panel is extended a distance beyond the spacer sealant for the gas chamber and holes are formed in a pattern in the dielectric, which holes contain circuit components as, for example, resistance elements and/or diodes. In another embodiment, various integrated circuit packages, such as LIDS, MSI, and LSI packages, are secured to the conductor ends, respectively.
