Patent ID: 8013824

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel to display an image; a panel driving unit configured to drive the liquid crystal display panel in response to panel driving voltages and a control signal; a timing controller configured to transmit a pixel data signal to the panel driving unit and to generate a control signal in response to a reference voltage; a direct current/direct current (“DC/DC”) converter configured to generate the panel driving voltages and the reference voltage; and a sequence control unit comprising: a voltage input/output unit configured to receive the panel driving voltages and the reference voltage from the direct current/direct current converter and to output the panel driving voltages and the reference voltage; a memory configured to store output timing data signals of the panel driving voltages and the reference voltage; a clock generating unit configured to generate a clock; a clock counter configured to count the clock in response to a counting signal, and configured to generate clock counting information; and a sequence controller configured to receive the output timing data signals of the panel driving voltages and the reference voltage from the memory, to supply the counting signal to the clock counter according to the output timing data signal of each of the panel driving voltages and the reference voltage, to control the voltage input/output unit in response to the clock counting information to delay the output of each of the panel driving voltages and the reference voltage.
