We have analyzed a displayed image of TFT-LCD three-dimensionally in case of low power drive using Multi-Field Driving Method (MFD). We have also proposed a concept of multi-media driving method using MFD in which a displayed image was divided into some interlaced subfield images and the number of interlaced subfields can be changed depending on the moving quantities of displayed images. This method made it possible not only to reduce a driving power consumption in case of still images to less than half, compared to that with conventional methods, but also to maintain high moving image quality.
