SOURCE DRIVER, METHOD FOR DRIVING DATA LINE, AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME

摘要

PROBLEM TO BE SOLVED: To easily adjust timing between a data signal and a clock. SOLUTION: A waveform shaping unit 20 shapes wave form of at least either each bit of a luminance data DL or a clock. A data latch unit 30 receives the luminance data DL and the clock CK output from the waveform shaping unit 20 and latches each bit of the luminance data DL by the clock CK. The waveform shaping unit 20 shapes wave form of at least either each bit of the luminance data DL or the clock CK in such a manner that the latched data of a calibration data Dc included in at least one bit of the luminance data DL by the clock CK is equal to the expected value.
