  • Liquid crystal display device and method with a reduced number of delay devices for discharging remaining pixel charges
    Patent number: 8253719
    Abstract: A liquid crystal display device and a method of driving the same is disclosed, which can minimize the number of delay devices to delay a discharging time by a preset period of time. The liquid crystal display device comprises a first pumping unit that first pumps a high-potential power source voltage applied; a second pumping unit that generates a gate high voltage by pumping the high-potential power source voltage first pumped in the first pumping unit; a level shifter that shifts an input high voltage to a level corresponding to that of the gate high voltage from the second pumping unit, and supplies the gate high voltage to a discharging circuit; and a delay device, connected between input and output sides of the second pumping unit, that maintains the gate high voltage output from the level shifter for a preset period of time.
