  • Patent number: 9818351
    Abstract: A LCD includes the sub-pixels arranged at least in two adjacent rows. The sub-pixels of the same color are interleaved with each other along the column direction. When the LCD displays a pure color frame, within the even-number arranging periods of the sub-pixels arranged along the column direction, a number of the sub-pixels of the same color being applied with the data signals having positive polarity are the same with the sub-pixels of the same color being applied with the data signals having negative polarity. In this way, the common electrode coupling caused by the transition of the data signals may be avoided. This eliminates the flicker issues and enhances the display performance of the LCD.
