ABSTRACT:
A liquid crystal display apparatus for presenting a high-quality image at a reduced power consumption comprises a liquid crystal display panel having scanning-signal electrodes and information-signal electrodes arranged in a matrix configuration, liquid crystals interposed between the scanning-signal electrodes and the information-signal electrodes, information electrode driving means for applying an information-signal voltage waveform to the information-signal electrodes, and scanning electrode driving means for applying a scanning-signal voltage waveform to the scanning-signal electrodes. The frequency of information-signal voltage waveform is lowered without changing the frame frequency of the apparatus by allowing two lines of scanning-signal electrodes to scan during a write pulse having a pulse length of .DELTA.T within one scanning period to select presentations of two pixels for each information-signal electrode.
