Abstract
A TFT array substrate for a TFT LCD includes a plurality of pixels each consisting of a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel arranged in a 2×2 matrix. Two data lines are located between each two neighboring columns of the sub-pixels. A scan line is located between two neighboring rows of the sub-pixels. The sub-pixels are driven by column inversion. The scan lines in electrical connections with different rows of the pixels are turned on successively along a vertical direction. Two neighboring same colored sub-pixels in a same row of the sub-pixels have opposite polarities and two neighboring same colored sub-pixel in a same column of the sub-pixels respectively have the same polarity when the TFT LCD is operated to output a screen having a color the same as the color of the two neighboring same colored sub-pixels.
