Liquid crystal display device and driving method thereof

A liquid crystal display device, characterized in that:

• comprising:
• a scan driving module for generating a first scan signal;
• a data driving module for generating a gray scale signal;
• pixels, each of which displays the gray scale signal according to the first scan signal, each pixel comprising at least two sub-pixels and pixel capacitors for re-assigning the gray scale signal to the sub-pixels;
• data lines connected with the data driving module and the pixels, respectively, each of the data lines controlling a charging voltage for the pixel according to the gray scale signal;
• shift register modules, each of which generates a second scan signal corresponding to one of the first scan signal based on the first scan signal;
• and
• scan lines including:
• type 1 scan lines connected with the scan driving module and the pixels, respectively, each of the type 1 scan lines controlling charging time for the pixel according to the first scan signal;
• and
• type 2 scan lines connected to the pixels, each of the type 2 scan lines controlling driving time for the sub-pixels of the pixel according to the second scan signal;
• the shift register module is connected with the type 1 scan line and the type 2 scan line corresponding to the type 1 scan line, respectively.

A liquid crystal display device driving method, characterized in that, the liquid crystal display device comprises:
