Abstract: an 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 pixels 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.
