    • In a liquid crystal display (16) having rows and columns of pixels (22), one or more selected rows of pixels are turned off (put in a standby mode) in a manner that saves power. A row of pixels is turned off by applying to the row a cyclical two-level voltage (BP2) having a magnitude that, when combined with voltages (FP3) applied to columns, results in each pixel in the selected row receiving a combined voltage (BP2-FP3) having a reduced number of transitions (30), having a magnitude that is insufficient to turn on a pixel, and having an average value of substantially zero over a cycle. The method is incorporated in a liquid crystal display apparatus (32) having a mode control (54) for switching selected rows of pixels between an active mode and a standby mode.
    • 在具有行和列的像素(22)的液晶显示器(16)中,以节省功率的方式将一个或多个所选择的像素行关闭(处于待机模式)。 通过向行施加具有幅度的周期性二电平电压(BP2)来关闭一行像素,该电平当与施加到列的电压(FP3)组合时导致所选行中的每个像素接收组合电压 BP2-FP3)具有减少的转换次数(30),具有不足以打开像素的量值,并且在一个周期上具有基本为零的平均值。 该方法结合在具有用于在活动模式和待机模式之间切换所选行像素的模式控制(54)的液晶显示装置(32)中。
