Abstract:
1. A 3D (3Dimensional) image display device comprising: An image display panel having a pixel array with a plurality of pixels arranged in a grid pattern and outputting image signals wherein a plurality of vertical columns of the pixel array are alternatively arranged to comprise columns for a left eye image only and for a right eye image only and each of the pixels is configured with a red sub-pixel, a green sub-pixel and a blue sub-pixel arranged in a vertical direction, a parallax barrier arranged in front of the image display panel, and having alternatively arranged a plurality of opaque vertical strips extended from top to bottom of the parallax barrier and a plurality of transparent strips each comprises a plurality of transparent portions being displaced alternately on a first side and a second side of a vertical line with a corner of each transparent portion adjacent a corner of another transparent portion on an opposite side of the vertical line, the parallax barrier being located so that each eye of a viewer can perceive one pixel of the pixel array through one of the transparent portions, and wherein when the image display panel is selected to operate odd horizontal rows of the pixels of the pixel array, whereby a left eye of the viewer at a first position can only perceive the operated pixels in the alternate vertical columns for left eye image only through the transparent portions on the first side of the vertical line and a right eye of the viewer at the first position can only perceive the operated pixels in the alternative vertical columns for right eye image only through the transparent portions on the first side of the vertical line, and wherein when the image display panel is selected to operate even horizontal rows of the pixels of the pixel array, whereby the left eye of the viewer at a second position can only perceive the operated pixels in the alternate vertical columns for left eye image only through the transparent portions on the second side of the vertical line and the right eye of the viewer at the second position can only perceive the operated pixels in the alternative vertical columns for right eye image only through the transparent portions on the second side of the vertical line.
