ABSTRACT:
A display driver is provided including: a code generator that generates pseudo random number sequences by a linear feedback shift register LFSR; a signal generator that receives the random number sequences output from taps Q3and Q4of the LFSR and generates field selection signals F1and F2that randomly vary field selection sequences; and a scan driver that outputs scan signals corresponding to the fields selected by the field selection signals F1and F2to the scan lines, and selectively drives the scan lines by a multi-line drive method. A field counter FDCT, whose load value is set by K bits of data with each bit configured based on random number sequences from K taps, increments or decrements its count value.
