Claim:
1. A display drive method for driving a 3D display device, the 3D display device comprising: a pixel array and a grating array, the pixel array comprising: a plurality of first view pixel groups; and a plurality of second view pixel groups; wherein the plurality of first view pixel groups and second view pixel groups are arranged alternately in both a row direction and a column direction, wherein each view pixel group includes M*N subpixels arranged in one column, wherein N represents a number of types of subpixel colors and M is an integer greater than or equal to 3 wherein the grating array shields a first side of the first view pixel group and a second side of the second view pixel group in the column direction, and wherein the first side and the second side are two opposite sides, the method comprising: dividing a first view and a second view to be displayed into a plurality of theoretical pixel units, respectively; determining a respective gray value corresponding to a color of each type of subpixels in original display information corresponding to each theoretical pixel unit; and for each subpixel of each view, determining brightness of the subpixel based on respective gray values corresponding to the color of the subpixel in the original display information corresponding to respective theoretical pixel units which are covered by a rectangular sampling region of the subpixel and belong to the view, wherein a midpoint of a connection line between a center of each subpixel and a center of each of respective neighboring subpixels of the same type is located on a boundary of the rectangular sampling region of the subpixel, subpixels being of the same type as one subpixel referring to the subpixels which belong to the same view and are in the same color as the subpixel.
