Abstract
A sequence control unit includes a voltage input/output unit to receive a driving voltage, and to output the driving voltage after a delay time. A memory stores an output time corresponding to the driving voltage, a clock generating unit generates a clock, a clock counter counts the clock in response to a counting signal, and a sequence controller supplies the counting signal corresponding to the output timing to the clock counter from the memory. The sequence controller receives the number of clock cycles or time associated with the number of clock cycles counted by the clock counter as clock counting information, and controls the delay time output of the driving voltage according to the clock counting information. A driving method for driving the sequence control unit is disclosed, and the sequence control unit may be included in a liquid crystal display device.
