Three-dimensional image display device

Abstract

A three-dimensional (“ 3 D”) image display device includes a display panel assembly which displays a two-dimensional (“ 2 D”) image including a left region and a right region, which are divided by an axis, and the display panel assembly repeatedly rotates back and forth by a predetermined angle with respect to the axis.

What is claimed is: 
     
         1 . A three-dimensional image display device comprising:
 a display panel assembly which displays a two-dimensional image comprising a left region and a right region, which are divided by an axis, and   wherein the display panel assembly repeatedly rotates back and forth by a predetermined angle with respect to the axis.   
     
     
         2 . The three-dimensional image display device of  claim 1 , further comprising:
 a first holder disposed at a side portion of the display panel assembly, and   a second holder disposed at a side portion of the display panel assembly.   
     
     
         3 . The three-dimensional image display device of  claim 1 , further comprising:
 a supporting member disposed at a side end of the display panel assembly, and   a moving member which repeatedly moves while being in contact with the supporting member,   wherein the display panel assembly is rotated by the supporting member and the moving member.   
     
     
         4 . The three-dimensional image display device of  claim 3 , wherein
 the moving member comprises:
 a body, 
 a bar which reciprocally moves within the body, and 
 a spring member which is fixed to an end portion of the bar, wherein the spring member is compressed and relaxed, and 
 wherein the spring member moves along the supporting member while being in contact with the supporting member. 
   
     
     
         5 . The three-dimensional image display device of  claim 3 , wherein
 the moving member comprises:
 a body; 
 a bar which rotates in a clockwise direction or a counterclockwise direction; and 
 a first protrusion which is fixed to a first end of the bar; 
 a second protrusion which is fixed to a second end of the bar, 
 wherein the first protrusion and the second protrusion alternately push or pull the supporting member while the first protrusion and the second protrusion are rotated while being fixed to the bar. 
   
     
     
         6 . The three-dimensional image display device of  claim 3 , wherein
 the moving member comprises:
 a body; 
 a bar which rotates in a clockwise direction or a counterclockwise direction; 
 a protrusion which is fixed to an end of the bar; and 
 a spring member which is fixed to the supporting member, 
 wherein the protrusion alternately pushes or pulls the supporting member while the protrusion is rotated being fixed to the bar. 
   
     
     
         7 . The three-dimensional image display device of  claim 3 , further comprising:
 a fixing member which fixes the display panel assembly and rotates back and forth by the predetermined angle by a repeated movement of the moving member,   wherein the moving member has a sinusoidal rail shape, and   wherein a rotation angle of the display panel assembly is substantially the same as a rotation angle of the fixing member.   
     
     
         8 . The three-dimensional image display device of  claim 1 , wherein
 the display panel assembly displays a compensated two-dimensional image, and   the compensated two-dimensional image is one of an image, in which the left region of the two-dimensional image is expanded and the right region of the two-dimensional image is reduced, and an image, in which the left region of the two-dimensional image is reduced and the right region of the two-dimensional image is expanded.   
     
     
         9 . A three-dimensional image display device comprising:
 a display panel assembly which displays a two-dimensional image comprising a left region and a right region,   wherein a front surface of the display panel assembly repeatedly moves back and forth by a predetermined distance.   
     
     
         10 . The three-dimensional image display device of  claim 9 , further comprising:
 an axis which fixes the display panel assembly, and   a guide member along which the axis moves back and forth.   
     
     
         11 . The three-dimensional image display device of  claim 9 , wherein
 the display panel assembly displays a compensated two-dimensional image, and   the compensated two-dimensional image is an image, in which an entire size of the two-dimensional image is expanded or reduced.
