3-DIMENSIONAL IMAGE-ANALYSIS OF MULTIFIELD DRIVING METHOD FOR REDUCING MULTIMEDIA LCD POWER-CONSUMPTION

We have analyzed a displayed image of TFT-LCD three-dimensionally in c ase of low power drive using Multi-Field Driving Method (MFD). We have also proposed a concept of multi-media driving method using MFD in wh ich a displayed image was divided into some interlaced subfield images and the number of interlaced subfields can be changed depending on th e 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 als o to maintain high moving image quality.
