<P>PROBLEM TO BE SOLVED: To provide a driving system of a display apparatus in which display unevenness originated in an output current value of a current conversion circuit is prevented. <P>SOLUTION: The driving system of the display apparatus comprises; a plurality of pixels including a current driving element arranged in a m-column and n-row matrix; n-pieces of current conversion circuits DAC1 to DACn that convert digital display signals D1 to Dn inputted from outside, to corresponding analog currents to output the currents; a first selector circuit 10 for selectively inputting the digital display signals D1 to Dn, to the n-pieces of current conversion circuits DAC1 to DACn; and a second selector circuit 20 for selectively supplying current outputs of the n-pieces of current conversion circuits DAC1 to DACn, to pixel groups of respective lines. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
