    摘要: A liquid crystal display driving circuit and method. A data register block of a controller applies in advance a polarity control signal to data before the data are stored in latches of a data driver, exchanges the data, and then stores the exchanged data in the latches. Thereby, it is possible to provide multiplexers, which are otherwise required for respective channels, to one controller and to decrease the size of a chip.
