<P>PROBLEM TO BE SOLVED: To provide a driving circuit which decreases a grayscale error by improving linearity by preventing a voltage drop caused across an analog switch, and an organic electroluminescence display apparatus using the same. <P>SOLUTION: The driving circuit which generates a data voltage includes: a first decoder adapted to output a plurality of first decoding signals using upper bits of a digital data signal; a switch unit adapted to select a first reference voltage and a second reference voltage corresponding to the plurality of first decoding signals; a second decoder adapted to output a plurality of second decoding signals using lower bits of the digital data signal; and a data voltage generation unit which includes a plurality of voltage distribution units adapted to receive and distribute the selected first and second reference voltages, where one voltage distribution unit is adapted to receive two second decoding signals to generate a data voltage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
