Abstract: A pixel array, a display driving device and a driving method thereof, and a display device are provided. The pixel array includes multiple columns of sub-pixel groups, each column of sub-pixel groups includes M×N sub-pixels arranged along a column direction, wherein the sub-pixel groups in odd numbered columns and the sub-pixel groups in even numbered columns offset in the column direction by ½ of a width of each sub-pixel in the column direction; each sub-pixel in each column of sub-pixel groups distorts in the column direction, and a distortion direction of the sub-pixel groups in the odd numbered columns is opposite to that of the sub-pixel groups in the even numbered columns. The crosstalk between the two views during 3D image displaying is improved by distortion of sub-pixels. A rendering method of the sub-pixels and 3D display are combined through the algorithm design, and the virtual resolution for each view is increased by algorithm compilation of 3D input signals, so as to make the display effect of 3D better.
