摘要： A capacitive load drive circuit that has reduced power consumption due to residual carriers, and a PDP apparatus using the same, have been disclosed. In the drive circuit, the power consumption due to the residual carriers, which are formed when a diode provided in parallel to a switch circuit of the capacitive load drive circuit is brought into conduction, is reduced and the switch circuit connected in parallel to the diode is brought into conduction during a period of time from when the diode is brought into conduction until when the potential of a terminal to which the diode is connected changes. By bringing the switch circuit connected in parallel into conduction, a closed circuit is formed by the diode and the switch circuit and the residual carriers formed in the diode are reduced. The voltage of the closed circuit is substantially zero V and, therefore, power consumption is very small even if a current due to the residual carriers flows through the closed circuit.

摘要： A signal transfer circuit in a pre-drive circuit converts the reference potential of a control signal, supplied from a drive control circuit, to the reference potential of an output element. The control signal is then amplified in a signal amplifier circuit and thereafter supplied to the output element. This makes it possible to isolate the reference potential and transfer the control signal to the output element even when the reference potentials of the drive control circuit and the control signal are different from that of the output element. The drive control circuit can also be prevented from being affected by variations in potential of the output element or the like.

摘要： A driving apparatus comprises switches SW1 to Sw3, a first signal line OUTA, and a second signal line OUTB. By ON/OFF control of the switches SW1 to Sw3, the voltage of the first signal line OUTA is changed between a positive voltage (+1/2V) level, which is smaller than a voltage V to be applied to a load 20, and the ground level, and the voltage of the second signal line OUTB is changed between the ground level and a negative voltage (−1/2V). By ON/OFF control of switches SW4 and SW5, the positive and negative voltages given by the first and second signal lines are selectively applied to the load 20. The maximum voltage applied to each element in the driving apparatus can be thereby lowered to the voltage (1/2V), which is smaller than the voltage V to be applied to the load 20. This makes it possible to hold down the breakdown voltage of each element to half the conventional value.
摘要翻译：驱动装置包括开关SW1至Sw3，第一信号线OUTA和第二信号线OUTB。通过开关SW1〜Sw3的ON / OFF控制，第一信号线OUTA的电压在小于施加到负载20的电压V的正电压（+ 1 / 2V）电平之间变化，以及接地电平和第二信号线OUTB的电压在接地电平和负电压（-1 / 2V）之间变化。通过开关SW4和SW5的ON / OFF控制，由第一和第二信号线给出的正电压和负电压被选择性地施加到负载20.施加到驱动装置中的每个元件的最大电压可以由此降低到电压（1 / 2V），其小于施加到负载20的电压V.这使得可以将每个元件的击穿电压压制成常规值的一半。

摘要： A PDP not posing the problem that previous display data appears at the time of activation, and a wave generating circuit capable of generating a complex wave without the necessity of expanding a quantity of ROM data and of increasing a reading speed have been disclosed. A plasma display panel display comprising a plasma display panel that includes a plurality of cells to be selectively discharged to glow, a reset unit for bringing the plurality of cells to a given state, an addressing unit for setting the plurality of cells to states associated with display data, and a sustaining discharge unit for enabling the plurality of cells to glow according to the set states further comprises an operation halt factor detector for detecting the fact that a factor of halting the operation of the plasma display panel has occurred, and an initialization unit that when it is detected that the operation halt factor has occurred, initializes memory information in the plasma display panel. In a wave generating circuit for generating a wave on the basis of ROM data that is stored in a ROM and concerned with a wave and its generation, the ROM data is stored while being split into basic period data that changes at intervals of a basic period and long period data that changes at intervals of a long period data. The basic period data and long period data are read at intervals of associated periods and converted at intervals of associated periods.

摘要： A method of driving a plasma display is disclosed, in which the deterioration of the display quality which otherwise might be caused by the light emission due to a reset pulse is prevented thereby to improve the display quality. The voltage of the reset pulse is set taking the voltage due to the accumulated charge into consideration in accordance with a specific display. In this way, the self-erasure discharge is not caused in all the cells but only in the cells involved in display. The display brightness is set also for the self-erasure discharge as a discharge involved in display like the sustaining discharge.
