摘要： A first and a second signal line respectively supplying a first potential and a second potential to one end of a capacitive load, a waveform output circuit whose input terminal is connected to a supply line supplying a third potential, whose output terminal is connected to the first or the second signal line, and whose control terminal is connected to a waveform generating circuit, and a reactive current preventing switch connected between the control terminal and the output terminal or the input terminal of the waveform output circuit are provided. During a period when a reactive current is prevented from flowing, the reactive current preventing switch is bought into conduction to make a potential difference between the control terminal and the output terminal of the waveform output circuit smaller so that the waveform output circuit cannot be operated, which prevents the reactive current from flowing, leading to an improvement in the reliability of a driving circuit.

摘要： A display apparatus includes a display panel including address electrodes and sustain electrodes crossing the address electrodes, with pixels being sandwiched between the address electrodes and the sustain electrodes. A sustain-electrode drive circuit selectively generates both sustain pulses and scan pulses and supplies them to the sustain electrodes. An address-electrode drive circuit generates address pulses based on a video signal and supplies the address pulses to the address electrodes. A control-signal generation circuit generates a control signal for controlling the sustain-electrode drive circuit to generate a selected one of the sustain pulses and the scan pulses and supplies the control signal to the sustain-electrode drive circuit. In order to display an image on the display panel, the sustain-electrode drive circuit both specifies addresses of pixels to be turned on and turns on the pixels at the specified addresses.

摘要： Sustain pulses are alternately applied to a pair of display electrodes of discharge cells provided in a plasma display panel (PDP) to generate a sustain discharge to display an image on the PDP. The sustain pulses include two-crests discharge voltage waveforms having a first maximum and second maximum values, in which discharges are generated twice in a half cycle. After applying a sustain pulse having a one-crest discharge voltage waveform to a pair of display electrodes, a predetermined number of sustain pulses of two-crests discharge voltage waveforms are consecutively applied. A time, from applying a second sustain pulse of a two-crests discharge voltage waveform to clamping a voltage of the second sustain pulse to the second maximum value, is made longer than a time, from applying a first sustain pulse of a two-crests discharge voltage waveform to clamping a voltage of the first sustain pulse to the second maximum value.

摘要： A method for driving a plasma display panel is provided in which wasteful power consumption is reduced and light emission efficiency is improved when the number of cells to be lighted is relatively small. The method includes classifying a display ratio into plural group ranges, selecting a suitable display pulse waveform for each group range, detecting the display ratio of an object to be displayed in a real display, and plural types of display pulses having different waveforms are used differently in accordance with the result of the detection. The display ratio means a ratio of the number of cells to be lighted to the number of cells of the screen.

摘要： Between a sustain circuit outputting a sustain pulse and a scan circuit (even) driving a Y electrode of an even display line, there is provided a first switch capable of making the Y electrode of the even display line be in a high impedance state, and between the sustain circuit and a scan circuit (odd) driving a Y electrode of an odd display line, there is provided a second switch capable of making the Y electrode of the odd display line be in the high impedance state. By first and second switches, the Y electrode of the even display line and the Y electrode of the odd display line can be independently controlled to be in the high impedance states, whereby discharge of the even display line can be restrained in a sustain period of an odd frame, while a discharge of the odd display line can be restrained in a sustain period of an even frame, thereby realizing an interlace drive without complicating a circuit configuration.
