DISPLAY APPARATUS HAVING AUTOSTEREOSCOPIC 3D OR 2D/3D SWITCHABLE PIXEL ARRANGEMENT

An autostereoscopic 3D display apparatus including a display panel having an array of pixels, and a lenticular device positioned above the display panel. The lenticular device includes an array of lenticular components extending in parallel with a line slanted at an angle of tan-1(a/mb) with regard to columns of the pixels, where m refers to the number of adjacent rows before an identical viewpoint on the same line appears, and a and b refer to horizontal and vertical lengths of each pixel. When n is 0 or a natural number, the number of viewpoints is 2m(2n+1), pixels corresponding to the given viewpoints are repeated at every m rows in each lenticular component, the number of parallel lines extending through pixels in parallel with the slant line inside each lenticular component is identical to the number of viewpoints, and each of the parallel lines lies on the repeated pixels.
