Abstract

An improved addressing scheme for plasma display panel control comprises partitioning the panel into a number of sections and splitting the addressing period into correspondingly small addressing periods for each section. By varying the time distance between successive addressing periods of the sections from one sub-field to the other, at least for the sub-fields with higher weights, a better spread of the energy input and output of the plasma display panel is achieved and the power supply circuit for the display panel may be constructed with less expensive components.
