Advanced plasma panel technology

摘要

A drive system for a plasma display device includes a background sustain generator which is divided between a discrete analog circuit and an integrated driver chip. The integrated driver chip includes low impedance switch pairs controlled by a pair of comparators which prevent the sustain signal from being degraded during discharge of the panel. By partitioning the elements of the sustain signal generator between discrete and integrated elements, optimum integration cost, circuit performance and system reliability are achieved.
