摘要： Provided is a technique of a PDP device capable of preventing error display arising from changes in discharge characteristics in a reset period particularly due to a long-period operation. In the PDP device, a slope of a slope waveform in the reset period is changed corresponding to operation time of the PDP device. And, the slope waveform is made to have a configuration having a stepwise plurality of slopes in a predetermined reset period. For example, when the operation time becomes long, rising and falling slope waveforms of a reset waveform are configured by two steps, and a first slope thereof is made steeper than a slope before the change, and a second slope is made gentle than the slope before the change. When the operation become longer, the first slope is made further steeper and the subsequent second slope is made further gentler.

摘要： This invention is directed to a technique capable of achieving image quality improvement by the control of reset thinning drive (second drive) in a PDP drive control and of restricting or reducing the generation of hunting in ON/OFF control of the second drive and flickering of background luminance particularly in the case of low-luminance display. In this PDP apparatus, in addition to the control of the second drive using the SF load ratio, the APL value (k) and APL variation value (q) of the field are used, and when the APL variation value (q) is less than a predetermined threshold value, even when the SF load ratio is changed from zero to a value other than zero between SFs, the execution of the first drive is not started, and the execution of the second drive is continued.
