LIQUID CRYSTAL DISPLAY DEVICE

摘要

By dynamically adjusting the DAC performance so that irregularities of liquid crystal panel characteristics are compensated, it is possible to provide a liquid crystal display device not increasing power consumption due to excessive DAC performance or not lowing display quality due to insufficient DAC performance. The liquid crystal display device includes: a digital/analog conversion circuit (4) for converting a data signal inputted as a digital signal into an analog signal; a source driver (3) inputting the analog signal outputted from the digital/analog conversion circuit (4) while distributing it into a plurality of source lines Y; a differential amplifier (5) for comparing voltage V<SUB>1</SUB> detected at the input side of the source line Y to voltage V<SUB>2</SUB> detected at the opposite side of the input side of the source line Y; and a correction circuit (6) for correcting the output of the digital/analog conversion circuit (4) according to the comparison result of the differential amplifier (5).
