Description
Technical Field
The utility model relates to a 3D shows, more specifically says, the utility model relates to an integrated formation of image double vision 3D display device based on rectangular polarization array.
Background
The integrated imaging double-vision 3D display is the fusion of a double-vision display technology and an integrated imaging 3D display technology. It may enable the viewer to see different 3D pictures in different viewing directions.
In a conventional integrated imaging dual view 3D display based on a polarized array:
(1) the micro image array comprises two groups of image elements which are arranged alternately in the horizontal direction and the vertical direction.
(2) Both groups of picture elements are square, i.e. the horizontal pitch of the picture elements is equal to the vertical pitch.
(3) The pinholes corresponding to the image elements are square and the horizontal pitch of the pinholes is equal to the vertical pitch.
(4) The polarizing elements corresponding to the picture elements are square shaped and the horizontal pitch of the polarizing elements is equal to the vertical pitch.
For televisions and displays, the ratio of the horizontal width to the vertical width of the television and display is 4:3, 16:10, or 16: 9. The disadvantages are that:
(1) the ratio of 3D pixels in the horizontal direction to 3D pixels in the vertical direction of a single 3D image is 4:3, 16:10 or 16: 9. The number of 3D pixels of a single 3D image in the integrated imaging dual view 3D display is half of the number of 3D pixels of a single 3D image in the integrated imaging 3D display. Therefore, the uneven distribution of the 3D pixels further affects the viewing effect.
(2) The horizontal viewing angle is much smaller than the vertical viewing angle.
For a handset, the ratio of the horizontal width to the vertical width of the handset is 3:4, 10:16, or 9: 16. The disadvantages are that: the ratio of 3D pixels in the horizontal direction to 3D pixels in the vertical direction of a single 3D image is 3:4, 10:16, or 9: 16. The number of 3D pixels of a single 3D image in the integrated imaging dual view 3D display is half of the number of 3D pixels of a single 3D image in the integrated imaging 3D display. Therefore, the uneven distribution of the 3D pixels further affects the viewing effect.
