Abstract :
Power consumption in liquid-crystal displays is analyzed by including frequent polarity reversals and duty-cycle control. A multistep voltage profile is proposed to reduce the power consumption of multiplexed and nonmultiplexed displays. The authors have also shown that the reduction in the power consumption can be achieved with a minimal increase in hardware complexity of the drive electronics
