    • 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. The pixel signal is not output to the data line during the masking interval.
    • 液晶显示装置包括液晶面板,栅极驱动器,数据驱动器和初始驱动控制单元。 液晶面板包括多个液晶单元。 每个液晶单元由栅极线,数据线和薄膜晶体管限定。 栅极驱动器根据栅极控制信号控制连接到每个液晶单元的栅极线的薄膜晶体管。 数据驱动器根据数据控制信号将像素信号输出到每个液晶单元的数据线。 数据驱动器包括连接到每个液晶单元的数据线的开关。 初始驱动控制单元被构造为将时钟计数与预定参考值进行比较,并且可操作以基于该比较交替地产生第一状态信号和第二状态信号。 在屏蔽间隔期间,该单元将第一状态信号施加到开关。 在屏蔽间隔期间,像素信号不输出到数据线。
