    摘要: In the driving circuit for a display apparatus according to the present invention, a charging circuit applies a voltage equal to or higher than the highest positive gradation voltage to each data line for a predetermined period of time before the start of a period for applying a positive gradation voltage. After that, a positive gradation voltage in accordance with data is applied to each data line. Then, a period for the applying a negative gradation voltage is started, when a negative gradation voltage in accordance with data is applied to each data line. Accordingly, after being charged with a voltage applied by the charging circuit at the beginning of each cycle of the AC driving, each data line is applied with an equal or lower gradation voltage. Alternatively, a discharging circuit first applies a voltage equal to or lower than the lowest negative gradation voltage to each data line for a predetermined period of time before the start of a period for applying a negative gradation voltage. After that, a negative gradation voltage in accordance with data is applied to each data line. Then, a period for applying a positive gradation voltage is started, when a positive gradation voltage in accordance with data is applied to each data line. Accordingly, after being discharged with a voltage applied by the discharging circuit at the beginning of each cycle of the AC driving, each data line is applied with an equal or higher gradation voltage.

    摘要: An inverter system which converts DC input into AC output and supplies the AC output to a load such as an FL tube detects change in a circuit current due to anomaly such as discharge without contacting with a current route. Relating to an inverter which converts DC input into AC output and supplies the AC output to a load, change in a circuit current of the inverter is detected through the medium of magnetic flux change due to the change in the circuit current caused by discharge. For example, if change in a current occurs in the circuit current of the inverter by disconnection discharge or ground-fault discharge occurring in a current route including a load of the inverter, magnetic flux change occurs in circuit wiring and a space of a core gap of a transformer of the inverter. The change in the circuit current is detected through the medium of the magnetic flux change without contacting with the circuit wiring or the transformer.
