Abstract: PURPOSE: A driving method of an LCD device having a backlight is provided to control a backlight according to a change of data, to realize high brightness on still images, thereby being applicable to both monitor having many still images and TV having many moving images. CONSTITUTION: When RGB data, synchronous, and clock signals are inputted(502), a device performs a data sampling process in a predetermined position(504). The device compares sampled data with previously sampled data(506). If two sampling values are different, the device increases a count value by 1(508). If the two sampling values are identical, the device stores new data in a previous data memory(510). The procedure is repeated for all sampling positions(512). The device decides whether the count value is more than 2(514). If so, the device sets the count value to 0(520), and generates a backlight off signal(522). If the count value is less than 2, the device sets the count value to 0(516), and generates a backlight on signal(518). The backlight on signal and the backlight off signal are transmitted to a timing controller(524).
