ABSTRACT:
A liquid crystal display comprises a liquid crystal display panel having a plurality of scanning electrodes and data electrodes, the data electrodes driving circuit has a latch at a front stage for fetching a display data of two lines for partial driving and a latch at a post stage for storing the display data of two lines. The display data from the latch at the post stage is compared with the scanning function supplied from the scanning driver, one of the voltages at three levels is selected in accordance with the result of the comparison, and the selected voltage is applied to the data electrodes. Further, the data electrode driving circuit has a latch for storing the result of the comparison for a period of one line and a correction voltage is applied to the data electrode in accordance with a value obtained by comparing an output of the latch and the comparison result.
