1. A method for driving a liquid crystal display (LCD) device, comprising: A 1 : extracting one image frame from a video; A 2 : dividing the one image frame into one left-eye image and one right-eye image according to different image arrangements, comparing a color data of the left-eye image with a color data of the right-eye image, and calculating a similarity degree between the left-eye image and the right-eye image of the different image arrangements according to the comparison; and A 3 : choosing the image arrangement having a maximum similarity degree between the left-eye image and the right-eye image as a film resource format of a three-dimensional (3D) image of the video, to drive the LCD device, wherein the image arrangement having the maximum similarity degree between the left-eye image and the right-eye image is the image arrangement of the one image frame, wherein the color data is a data code of red-green-blue (RGB) primary color of each of pixels, and the similarity degree is obtained through directly comparing the data code of RGB primary color of the pixel, wherein in calculating the similarity degree, a pixel difference value of each of the pixels is obtained, and a total difference value of one image frame is obtained, wherein in calculating the similarity degree, an exclusive-or (XOR) algorithm is used to calculate the pixel difference value, wherein a formula of the XOR algorithm is: 
 P ( x, y )=XOR(left( x, y ), right( x, y )) wherein the left (x, y) is regarded as the data code of the RGB primary color of the pixel positioning coordinate site (x, y) of the left-eye image, the right (x, y) is regarded as the data code of the RGB primary color of the pixel positioning coordinate site (x, y) of the right-eye image, and the P (x, y) is regarded as the pixel difference value between the pixel positioning coordinate site (x, y) of the left-eye image and the pixel positioning coordinate site (x, y) of the right-eye image; the XOR algorithm is performed for each of bits of the data code of the RGB primary color of the pixels of the left-eye image and the right-eye image, and the pixels of the left-eye image and the right-eye image are corresponding in position; when values of corresponding bits of the pixels of left (x, y) and right (x, y) are same, number 0 is output; when the values of corresponding bits of the pixels of left (x, y) and right (x, y) are different, number 1 is output; XOR values of different bits of the pixels of left (x, y) and right (x, y) are accumulated to obtain the pixel difference value P between the two corresponding pixels.
