ABSTRACT:
In a passive liquid crystal display, frames or fields are displayed for different time periods to achieve gray scale. The voltage pulses applied to the column electrodes have substantially constant values during row scanning periods or field scanning periods to reduce power consumption. The lines of the display may be divided into odd and even fields in an interlaced configuration to suppress flicker and to further reduce power consumption by reducing frame rate.
