Patent ID: 8766882

Claim:
An apparatus for displaying a three-dimensional image, comprising: a display unit including a plurality of first and second groups of sub-pixels respectively colored, each of the first and second groups of sub-pixels being arranged in an array of rows in a first direction and the first and second groups of sub-pixels being adjacently arranged in columns in a second direction, each of the sub-pixels having an opening area and first and second light shielding areas, the first light shielding area extending in the first direction between the first and second groups of the sub-pixels to separate the opening areas in the first group of the sub-pixels from the opening areas in the second group of the sub-pixels, and the second light shielding areas being located between the opening areas of the adjacent sub-pixels in each of the first and second groups to separate the opening areas of the adjacent sub-pixels, wherein each opening area has a plurality of opening lengths extending in the second direction; opening lengths of opening areas in each of the first and second groups of the sub-pixels, as distributed along the first direction, are substantially inconstant; and integrated lengths of opening areas in the first and second groups of the sub-pixels, as distributed along the first direction, are more constant than the opening lengths of opening areas in each of the first and second groups of the sub-pixels, each of the integrated lengths corresponding to a sum of the opening lengths of two immediately adjacent opening areas separated by the first light shielding area in the first and second groups of sub-pixels; and a light ray control unit, facing the display unit, configured to control light rays from the sub-pixels of the display unit, the light ray control unit including a plurality of optical openings extending substantially linearly in the second direction and arranged in the first direction.
