    • A display apparatus includes a display panel having a matrix structure formed by a scan electrode group and a data electrode group, a scan electrode drive unit for operating the scan electrode group, a data electrode drive unit for operating the data electrode group, and a switching unit for switching on/off the electrical connection between a drive voltage generating unit for supplying drive voltage to the drive unit and a power supply source for supplying power to the drive voltage generating unit. Also included is a detection unit for detecting that the switching unit has been switched off, and a control unit for controlling the scan electrode drive unit and data electrode drive unit to apply a display drive signal for causing the display panel to display a desired image according to image information when the switching unit is switched on and to apply, to the scan electrode group and the data electrode group, non-pixel portion control voltage signals for controlling the optical state of liquid crystal in non-pixel portions which are regions except for intersection portions between the scan electrode group and the data electrode group immediately after or after the switching unit has been switched off.
    • 显示装置包括具有由扫描电极组和数据电极组形成的矩阵结构的显示面板,用于操作扫描电极组的扫描电极驱动单元,用于操作数据电极组的数据电极驱动单元,以及切换 用于接通/关闭用于向驱动单元提供驱动电压的驱动电压产生单元和用于向驱动电压产生单元供电的电源之间的电连接的单元。 还包括用于检测切换单元已被关闭的检测单元,以及控制单元,用于控制扫描电极驱动单元和数据电极驱动单元,以施加显示驱动信号,使显示面板根据 当切换单元被接通并且向扫描电极组和数据电极组施加用于控制非像素部分中的液晶的光学状态的非像素部分控制电压信号时,图像信息是除了 在切换单元关闭之后或之后的扫描电极组和数据电极组之间的交叉部分。
