dc.description.abstract	Power consumption in liquid crystal displays is analyzed by including frequent polarity reversals and duty cycle control. A multi-step voltage profile is proposed to reduce the power consumption in multiplexed and non-multiplexed displays. The present invention relates to a method to optimize power consumption in Liquid Crystal Display, wherein said method comprises steps of: applying multi-step waveform for selecting pre-determined address lines, maintaining ratio of step-width (Ts) and pulse width (T) between 0.02 to 0.25, and making final step duration (Tf) greater than or equal to twice the step width (Ts) to optimize power supply of the Liquid Crystal Display and apply a correction voltage if the distortion is significant and modifying the step sizes to reduce the supply voltage of the driver.	en
