Stereoscopic display

Abstract

A stereoscopic display includes: a display panel in which sub-pixels of a plurality of colors are arranged in a predetermined arrangement pattern; and a parallax barrier having a barrier pattern including transmission sections allowing light to pass therethrough and a shielding section shielding light. The arrangement pattern and the barrier pattern are configured in such a manner that stereoscopic vision is achieved when the display panel and the parallax barrier are both in a first arrangement state and in a second arrangement state, the first arrangement state and the second arrangement state having such a positional relationship that vertical direction and horizontal direction are interchanged with each other.

The invention is claimed as follows: 
     
         1 . A stereoscopic display comprising:
 a display panel in which sub-pixels of a plurality of colors are arranged in a predetermined arrangement pattern; and   a parallax barrier having a barrier pattern including transmission sections allowing light to pass therethrough and a shielding section shielding light,   wherein the arrangement pattern and the barrier pattern are configured in such a manner that stereoscopic vision is achieved when the display panel and the parallax barrier are both in a first arrangement state and in a second arrangement state, the first arrangement state and the second arrangement state having such a positional relationship that vertical direction and horizontal direction are interchanged with each other, and   wherein the sub-pixels arranged in a repeating pattern includes four different pixel groups that are arranged in triangular shapes and that are offset from one another.   
     
     
         2 . The stereoscopic display according to  claim 1 , wherein in the second arrangement state, stereoscopic vision is achieved by using each sub-pixel in the horizontal direction and using sub-pixels in every other vertical line in the vertical direction. 
     
     
         3 . The stereoscopic display according to  claim 1 , wherein in the second arrangement state, stereoscopic vision from two viewpoints is achieved with use of first pixel groups for the first viewpoint and third pixel groups for the third viewpoint, and the barrier pattern is configured to shield the second and fourth pixel groups. 
     
     
         4 . The stereoscopic display according to  claim 1 , wherein
 when in the first arrangement state, sub-pixels for different respective viewpoints in stereoscopic vision are cyclically arranged along the horizontal line in such a manner that a first sub-pixel in a first horizontal line and a second sub-pixel in a second horizontal line immediately adjacent to the first horizontal line, the second sub-pixel immediately adjacent to the first sub-pixel in the vertical direction, are arranged for respective viewpoints different from each other.   
     
     
         5 . The stereoscopic display according to  claim 4 , wherein
 when in the first arrangement state, the transmission sections are arranged in such a manner that one transmission section is allocated for every a plurality of sub-pixels in the horizontal direction, and   the transmission sections in the first and second horizontal lines are arranged in a staggered configuration in such a manner that each of the transmission sections in the first horizontal line is arranged at a position shifted from the corresponding transmission section in the second horizontal line by an offset distance of the predetermined number of sub-pixels.   
     
     
         6 . The stereoscopic display according to  claim 5 ,
 the display panel displays, both in the first and second arrangement state, utilizes a combination of sub-pixels of multiple colors forming a triangle as a unit pixel.   
     
     
         7 . The stereoscopic display according to  claim 1 , wherein in the second arrangement state, the number of viewpoints in stereoscopic vision is smaller than that in the first arrangement state. 
     
     
         8 . The stereoscopic display according to  claim 1 , wherein in the second arrangement state, the number of viewpoints in stereoscopic vision is smaller than that in the first arrangement state.
