    • A display panel of the liquid crystal type provides a positive color display of segments or unit display areas using a reduced number of divided electrodes and an increased number of different driving signals. On one side of the panel there is a separate electrode encompassing each display area and all such electrodes include a display area. On the other side there are several common electrodes, each encompassing at least one display area and all cumulatively encompassing all of the display areas. A display area is selected for display by applying driving signals to its opposed electrodes such that substantially zero voltage is across the selected display area thereby leaving colored appearance in the selected display area. All other display areas and background areas are decolored by applying to the respective opposed electrodes driving signals resulting in a liquid crystal threshold voltage being applied across said non-selected display areas and said background areas.
    • 液晶型显示面板使用减少数量的分割电极和增加不同的驱动信号数量来提供段或单位显示区域的正彩色显示。 在面板的一侧,存在包围每个显示区域的单独电极,并且所有这些电极包括显示区域。 另一方面,存在几个公共电极,每个电极包括至少一个显示区域,并且全部累积地覆盖所有的显示区域。 通过向其相对的电极施加驱动信号来选择显示区域,使得显示区域上的电压基本为零,从而在所选择的显示区域中留下彩色外观。 所有其它显示区域和背景区域通过施加到相应的相对电极驱动信号而被去色,导致在所述未选择的显示区域和所述背景区域上施加液晶阈值电压。
