Abstract

Two techniques to reduce the power needed for driving 1-pixel LCDs (liquid crystal displays) are proposed. The first one is the use of multiple capacitors and the second is dividing the LCD into two to lower the drive voltage. Simulations show that large capacitance and many capacitors can reduce the power, and stacking two thin LCDs driven by lower voltage maximizes the effect of the proposed technique, especially for small LCDs. An experiment on the former technique using actual PDLCDs (polymer dispersed liquid crystal displays) confirms that it works as effectively as the simulation implies. The overall energy consumption of large PDLCDs is reduced more than 70%.
