    • A power supply device of a video display apparatus and a method thereof is capable of improving operation reliability of a video display apparatus, preventing erratic operation of the video display apparatus caused by higher harmonics and preventing erratic operation of other apparatus caused by unnecessary transmitted radiative wave. The power supply device can include a rectifying section for converting AC power into DC power, a harmonics suppressor for cutting off higher harmonics included in the DC power and a smoothing circuit for smoothing the higher harmonics cut-off DC power. A standby power supplier is for supplying the smoothed DC power to the video display apparatus as standby power, a main power supplier is for supplying the smoothed DC power to the video display apparatus as main power and a control unit is for controlling an operation of the harmonics suppressor.

    • A liquid crystal display device and a driving method thereof for preventing a color distortion phenomenon in a field-sequential driving system are disclosed. In the liquid crystal display device, a data driver sequentially supplies a green data signal, a red data signal and a blue data signal to the data lines. A gate driver applies a scanning pulse to gate lines. A light source irradiates a green light onto a liquid crystal cell during a time interval when the green data signal is maintained at the liquid crystal cell, irradiates a red light onto the liquid crystal cell during a time interval when the red data signal is maintained at the liquid crystal cell, and irradiates a blue light to the liquid crystal cell during a time interval when the blue data signal is maintained at the liquid crystal cell.
    • 公开了一种用于防止场顺序驱动系统中的颜色失真现象的液晶显示装置及其驱动方法。 在液晶显示装置中,数据驱动器向数据线依次提供绿色数据信号,红色数据信号和蓝色数据信号。 栅极驱动器将扫描脉冲施加到栅极线。 在绿色数据信号保持在液晶单元的时间间隔期间,光源将绿色光照射到液晶单元上,在红色数据信号保持在时间间隔期间将红色光照射到液晶单元上 在蓝色数据信号保持在液晶单元的时间间隔期间,向液晶单元照射蓝色光。
