  • Patent number: 9087493
    Abstract: A liquid crystal display device includes a liquid crystal panel, a gate driver, a data driver, and an initial driving control unit. The liquid crystal panel includes a plurality of liquid crystal cells. Each liquid crystal cell is defined by a gate line, a data line and a thin film transistor. The gate driver controls the thin film transistor connected to the gate line of each liquid crystal cell according to a gate control signal. The data driver outputs a pixel signal to the data line of the each liquid crystal cell according to a data control signal. The data driver includes a switch connected to the data line of the each liquid crystal cell. The initial driving control unit is structured to compare a clock count with a predetermined reference value and operable to alternately generate a first state signal and a second state signal based on the comparison. The unit applies the first state signal to the switch during a masking interval.
