Patent ID: 8098220

Claim:
A liquid crystal display, comprising: a plurality of data lines configured to be provided with two-step signals sequentially, each of the two-step signals comprising a first voltage signal and a second voltage signal different from the first voltage signal; a plurality of scan lines crossing said data lines, wherein said scan lines are grouped into a first group and a second group, and scan lines of the first group and scan lines of the second group are alternatively arranged; a plurality of pixels each defined by two neighboring data lines and two neighboring scan lines crossing the two neighboring data lines, the two neighboring scan lines comprising a first scan line in the first group and a second scan line in the second group; a plurality of common electrodes disposed in corresponding pixels to define said pixels into a plurality of first sub-pixels and a plurality of second sub-pixels; a plurality of first switching devices respectively disposed in the first sub-pixels and electrically connected to corresponding data lines; a plurality of second switching devices respectively disposed in the second sub-pixels, electrically connected to corresponding data lines through said first switching devices disposed in the first sub-pixels respectively, wherein the first voltage signal is written to the first sub-pixel in one of said pixels through said first switching device when the first scan line and the second scan line coupled to the same one of said pixels are both driven, and the second voltage signal is written to the second sub-pixel in the same one of said pixels through said second switching device when the second scan line within the same one of said pixels and the first scan line coupled to a next one of said pixels are both driven; a plurality of first pixel electrodes electrically coupled to said first switching devices respectively, wherein said first pixel electrodes receive data from data lines through said first switching devices; and a plurality of second pixel electrodes electrically coupled to said second switching devices respectively, wherein said second pixel electrodes receive data from data lines through said first switching devices disposed in the first sub-pixels and said second switching devices disposed in the second sub-pixels.
