Plasma Display Device

摘要

Provided is a plasma display device for controlling the power voltage of a pre-drive circuit in a manner to correspond to the change in a display percentage. The plasma display device is characterized in that the display percentage of a display screen is detected from a signal inputted, so that the amplitude of a drive pulse to be fed to a sustain output element is controlled on the basis of the display percentage, and in that a sustain current to flow for a sustain period is detected by a sustain current detection circuit so that the amplitude of a drive pulse to be fed to the sustain output element is controlled on the basis of the detection result.
