Patent ID: 8462080

Claim:
A display device, comprising: a display cell having a plurality of sub-pixels to make a single image or dual images, the plurality of sub-pixels including a first group for displaying a first image of the dual images and a second group for displaying a second image of the dual images; and a control cell for passing through the single image, and guiding the first image toward a first direction and the second image toward a second direction different from the first direction, wherein the control cell includes a plurality of first electrodes spaced apart from each other and a plurality of second electrodes spaced apart from each other, wherein the plurality of first electrodes face the plurality of second electrodes, wherein the control cell includes first and second regions alternately arranged, the first and second regions are transparent for the single image, and the first and second regions are alternatingly transparent and opaque, respectively, for displaying the dual images, wherein a width of the first region is determined according to a first number of the plurality of first and second electrodes that a voltage is not applied and a width of the second region is determined according to a second number of the plurality of first and second electrodes that the voltage is applied, wherein the first and second directions are controlled by the widths of the first and second regions, wherein the plurality of sub-pixels include first and second alternately arranged sub-pixels, and the first and second sub-pixels make the first and second images, respectively, wherein each of the first and second sub-pixels has first, second and third colors such that the first sub-pixel of the first color, the second sub-pixel of the first color, the first sub-pixel of the second color, the second sub-pixel of the second color, the first sub-pixel of the third color and the second sub-pixel of the third color are sequentially arranged, wherein the first and second sub-pixels having the same color adjoin each other, and wherein the first region overlaps the two adjacent first and second sub-pixels having the same color and the second region overlaps the two adjacent first and second sub-pixels having the different color.
