Abstract
In a liquid crystal display device that performs two-line inversion driving, a difference of a write period of a substantial video signal between a pair of pixel rows scanned with the same polarity is compensated. An input signal pre-processing circuitreceives display data DATA and an original data enable signal DTMG, generates and inputs a data enable signal DTMG_R and display data DATA_R to a driver control signal generation block. DTMG_R is reduced in the active period, and an interval of the active period between a (2n−1)-th row and a 2n-th row is set to be larger than an interval of the active period between the 2n-th row and a (2n+1)-th row. The input signal pre-processing circuitreads out DATA of each row from a buffer as DATA_R in an active period of DTMG_R.
