    • 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.
    • 在根据本发明的显示装置的驱动电路中,充电电路在施加正的周期开始之前的预定时间段期间向每个数据线施加等于或高于最高正灰度级电压的电压 灰度电压。 之后,根据数据的正的灰度级电压被施加到每个数据线。 然后,当根据数据的负灰度电压被施加到每个数据线时,开始施加负灰度电压的周期。 因此,在交流驱动的每个周期开始时,由充电电路施加的电压充电之后,对每个数据线施加相等或更低的灰度电压。 或者,放电电路首先在施加负灰度电压的周期开始之前的预定时间段向每个数据线施加等于或低于最低负灰度电压的电压。 之后,根据数据的负灰度电压被施加到每个数据线。 然后,当根据数据的正的灰度级电压被施加到每个数据线时,开始施加正的灰度级电压的周期。 因此,在AC驱动的每个周期开始时,由放电电路施加的电压放电后,每个数据线被施加相等或更高的灰度电压。
