摘要： A predrive circuit, a drive circuit and a display device which are capable of driving output elements so as to transmit control signals stably even when reference potentials generated on the output elements side turn to high voltage. A first level shift circuit outputs a flow signal which is an input signal according to a first level shift potential. A second level shift circuit outputs a flow signal which is the flow signal output from the first level shift circuit, according to a second reference potential. A level shift power supply circuit supplies the level shift potential based on a prescribed power supply voltage and the second reference potential to the first level shift circuit and the second level shift 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 ramp waveform generation circuit for generating a ramp waveform to be applied to a capacitive load serving as a display element is connected between the ground and a signal line for supplying a high-level voltage generated by a power supply circuit for generating a voltage to be applied to the capacitive load, thereby operating the ramp waveform generation circuit with reference to the ground potential. Hence, without using a plurality of power supply circuits or a signal transmission circuit for converting the reference potential of a control signal for the ramp waveform generation circuit, a stable ramp waveform can be output with a simple circuit arrangement.

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.

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。
