Claim Text:
1. A liquid crystal display (LCD) fixing flicker in 3D image display, comprising: a scan line for sending a scan signal; a data line for sending a grey level signal; pixel units comprising a first sub-pixel and a second sub-pixel; a data controlling signal generator for generating a first data controlling signal and a second data controlling signal; a controlling signal generator for generating a first controlling signal, a second controlling signal, a third controlling signal and a fourth controlling signal; a charge sharing signal source for generating a charge sharing signal; a first data switch, electrically connected to the data line and the first sub-pixel, for conducting the grey level signal to the first sub-pixel when receiving the first data controlling signal; a second data switch, electrically connected to the data line and the second sub-pixel, for conducting the grey level signal to the second sub-pixel when receiving the second data controlling signal; a first switch unit, electrically connected to the scan line and the first sub-pixel, for conducting the scan signal to the first sub-pixel when receiving the first controlling signal; a second switch unit, electrically connected to a constant voltage and the first sub-pixel, for conducting the constant voltage to the first sub-pixel when receiving the second controlling signal; a third switch unit, electrically connected to the scan line and the second sub-pixel, for conducting the scan signal to the second sub-pixel when receiving the third controlling signal; a fourth switch unit, electrically connected to the constant voltage and the second sub-pixel, for conducting the constant voltage to the second sub-pixel when receiving the fourth controlling signal; and a charge sharing switch, electrically connected to the charge sharing signal source, the first sub-pixel and the second sub-pixel, for electrically connecting the first sub-pixel to the second sub-pixel when receiving the charge sharing signal and turning on, wherein a process of the scan line sending the scan signal to the pixel units comprises a first period of time, a second period of time and a third period of time when the LCD is under 2D image mode; during the first period of time, the first data switch, the first switch unit and the fourth switch unit are turned on while the second data switch, the second switch unit, the third switch unit and the charge sharing switch are turned off, resulting in the first sub-pixel displaying grey level according to the grey level signal; during the second period of time, the second data switch, the second switch unit and the third switch unit are turned on while the first data switch, the first switch unit, the fourth switch unit and the charge sharing switch are turned off, resulting in the second sub-pixel displaying grey level according to the grey level signal; and during the third period of time, the second switch unit, the fourth switch unit and the charge sharing switch are turned on while the first switch unit and the third switch unit are turned off, resulting in the first sub-pixel electrically connecting to the second sub-pixel.
