Patent ID: 7619815

Claim:
A parallax barrier for a three-dimensional display device, the three-dimensional display device including an image display unit having sub-pixels for displaying a display image having a left-eye image part and a right-eye image part, the sub-pixels including a plurality of left-eye sub-pixels for displaying the left-eye image part and a plurality of right-eye sub-pixels for displaying the right-eye image part, the sub-pixels being organized into a sub-pixel array of rows and columns, each of the rows extending in a row direction and each of the columns extending in a column direction, wherein the parallax barrier is configured to provide the display image to a viewer as a three-dimensional image at a visual range by separating the display image to the left-eye image part and the right-eye image part, the parallax barrier comprising: a plurality of light interception portions and a plurality of light transmission portions arranged in a plurality of parallax barrier rows corresponding to the rows of the sub-pixel array, the light transmission portions having respective centers in the row direction, such that the centers of the light transmission portions in each of the parallax barrier rows are fixedly offset from the centers of the light transmission portions in at least one other row of the parallax barrier rows during at least one frame of the display image, and each of the light transmission portions corresponds to a region between at least one of the left-eye sub-pixels and at least one of the right-eye sub-pixels that are adjacent each other, so as to transmit the left-eye image part toward a left eye of the viewer and to transmit the right-eye image part toward a right eye of the viewer.
