ABSTRACT:
This driving device for a display apparatus includes display driving circuit element regions, which are physically separated for a plurality of display data, respectively. In each of the display driving circuit element regions, the driving device includes at least a display data capturing portion for capturing display data corresponding to the region; a holding portion for latching the captured display data for a predetermined period of time; a reference voltage generating portion for generating a predetermined number of reference voltages for gray-scale display; and a selecting portion for selecting a reference voltage corresponding to the latched display data from the generated reference voltages for gray-scale display, wherein the reference voltage selected for each of the plurality of display data is output to the display apparatus as a display driving signal.
