[Prior Art] [0002] With the advancement of technology and the improvement of the quality of life, information products have penetrated into every corner of life, and liquid crystal display devices play an important role in them. The main component of the liquid crystal display device is a liquid crystal panel. The liquid crystal panel is composed of a plurality of pixels. Each pixel includes three sub-pixels displaying three primary colors of red, green and blue. Each sub-pixel is provided with a scanning signal by a scanning line. The data voltage is provided by a data line, and the light and dark of each sub-pixel are controlled by the driving circuit, so that the three primary colors are proportionally adjusted to display the color of the full color mode. [0003] A plurality of sub-pixels of a liquid crystal panel are arranged in a plurality of ways, and the most commonly used ones are a stripe and a mosaic, as shown in FIG. 1 and FIG. 2, respectively. Each sub-pixel of each column of the liquid crystal panel arranged in a straight line is arranged in the order of red, green and blue, and each sub-pixel of each row is one of red, green and blue sub-pixels at the same time. In the order of red, green, blue, red, green, blue, etc., each sub-pixel of each row is red, blue, green, red, blue, green. The order of .... [0004] In the straight strip arrangement, each row is a sub-pixel of the same color, so that when a straight line is used to display a monochrome line, the display effect is better. However, when a straight line is used to display a monochrome diagonal line, since two different color sub-pixels are always spaced between two sub-pixels along the diagonal direction of the liquid crystal panel, the display surface is obviously discontinuous, as shown in the figure. 3 is shown. 095143007 Form No. A0101 Page 3 of 25 0993437443-0 1339284

[0005] In the mosaic arrangement: the same color sub-pixels are along each diagonal direction, so when the monochrome display is used for the mosaic, the display effect is better. However, when a mosaic line is used, since the two sub-pixels of the same color are always spaced by two different color sub-pixels, the display screen will have a distinct zigzag shape as shown in FIG. _ [0006] The above is to analyze the shortcomings of the straight-line and Marseille styles in the prior art by displaying the simplest picture, and the above problems are more prominent when displaying more complicated pictures.
