Advanced Multi-Field-Driving Method for Low Power TFT-LCDs

Abstract

An advanced multi-field-driving method that reduces not only the dynamic power consumption, but also the static power consumption of LCD driving circuits has been developed. The applicability of this method was confirmed by using a 9.5″ VGA TFT-LCD. Total driving circuit power consumption was reduced to less than half that of a conventional 60 Hz driving method for all displayed images. In addition, the displayed images obtained were sufficient for practical use and had no visible image degradation, such as flicker and crosstalk.
