Patent ID: 7161591

Claim:
A driving device for a display apparatus, comprising: a plurality of display driving circuit element regions physically separated from one another and each for a plurality of display data, each of the display driving circuit element regions including 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 given period of time; a reference voltage generating portion for generating a given number of reference voltages for gray-scale display, a selecting portion for selecting a reference voltage corresponding to the latched display data from the generated reference voltages for gray-scale display, and a plurality of terminals including a pair of reference power supply terminals arranged between two pairs of output terminals along a top surface of each display driving circuit element region, and including two pairs of data input terminals arranged along a bottom surface of each display driving circuit element region, and wherein the reference voltage selected for each of the plurality of display data is output to the display apparatus as a display driving signal.
