Abstract

A data driver outputs image data to a liquid crystal panel, using a trailing edge of a timing signal as a trigger. When a user operates a remote control for power-off, a main controller outputs, to a driver controller, a stop signal for stopping the timing signal, and a power switching signal for switching the image data to a low power for output after a predetermined time from the stop signal. Accordingly, the image data is switched to a low power for standby mode after the supply of the timing signal to the data driver is completely stopped. Thus, when the data driver outputs image data to the panel in response to a last pulse of the timing signal, the data driver is prevented from outputting image data having been switched to a low power, so that noise can be prevented from appearing on the screen of the panel.
