PLASMA DISPLAY UNIT, AND METHOD FOR DRIVING PLASMA DISPLAY PANEL

摘要

A plasma display unit performs the heat automatic power control to set up a total number of luminescent pulses, that is a total number of sustain pulses per one display frame according to a display load ratio, while decreasing the setup total number of luminescent pulses in the event of detection of a condition on which thermal destruction or burning may occur in a plasma display panel. In generating first sustain pulses to be clamped to a specified voltage before generation of sustain discharging and second sustain pulses to be clamped to the specified voltage after generation of sustain discharging, a ratio of a number of the first sustain pulses to a number of the second sustain pulses is made different in OFF state (Heat APC OFF) and in ON state (Heat APC ON) of the heat automatic power control.
