    • PURPOSE: A plasma display device facilitates a touch operation without arranging a separate touch device on the front of a panel by setting at least one subfield as a vertical scan subfield and at least one subfield as a horizontal scan subfield among multiple subfields of a frame. CONSTITUTION: A plasma display device includes a plasma display panel with a front substrate in which a scan electrode (202) and a sustain electrode (203) are arranged and a back substrate (211) in which an address electrode crossing the scan electrode and the sustain electrode is arranged; a touch means for touching a predetermined position on a screen of the plasma display panel or a predetermined object displayed on the screen of the plasma display device; and a drive unit for forming images by supplying a drive signal to the plasma display panel corresponding to a frame including multiple subfields. The drive unit supplies the drive signal to the plasma display panel at a first point according to a normal mode and supplies the drive signal to the plasma display panel at a second point different from the first point according to a touch mode.
    • 目的:通过在帧的多个子场中设置至少一个子场作为垂直扫描子场和至少一个子场作为水平扫描子场,等离子体显示装置便于触摸操作,而不需要在面板前面设置单独的触摸装置。 等离子体显示装置包括:等离子体显示面板,其具有配置有扫描电极(202)和维持电极(203)的前面基板和背面基板(211),其中与扫描电极交叉的寻址电极和 维持电极; 用于触摸等离子体显示面板的屏幕上的预定位置或显示在等离子体显示装置的屏幕上的预定对象的触摸装置; 以及驱动单元,用于通过向对应于包括多个子场的帧的等离子体显示面板提供驱动信号来形成图像。 驱动单元根据正常模式在第一点处将驱动信号提供给等离子体显示面板,并且根据触摸模式在不同于第一点的第二点处将驱动信号提供给等离子体显示面板。
