ABSTRACT:
A display apparatus in which the light transmittance of a pixel selected by a scanning electrode and a data electrode is changed in correspondence with a difference of voltages applied to the scanning electrode and the data electrode has a display panel having a plurality of scanning electrodes and a plurality of data electrodes, a signified video signal forming device for forming signified video signals by distributing digital video signals in a picture to subpictures having the same number as bits each having a bit significance; an orthogonal function generator for generating orthogonal function signals having substantial orthogonality; an orthogonal transformation signal generator for receiving the signified video signals and the orthogonal function signals to operate and output data signals; a scanning voltage generator for receiving scanning signals to apply scanning voltages to the scanning electrodes of the display panel; and a data voltage generator for receiving data signals to apply data voltages to the data electrodes of the display panel, wherein the scanning voltage generator and the data voltage generator are such ones that the peak value of a driving voltage, in each of the subpictures, applied to the display panel as a voltage difference between the scanning voltage and the data voltage corresponds to a significance value of a bit of the digital video signals.
