Description

Integrated imaging double-vision 3D display device based on rectangular polarization array
Technical Field
The present invention relates to 3D displays, and more particularly to an integrated imaging dual vision 3D display device based on a rectangular polarizing array.
Background
The integrated imaging dual-view 3D display is a fusion of the dual-view display technology and the integrated imaging 3D display technology. It may enable a viewer to see different 3D pictures in different viewing directions.
In conventional integrated imaging dual vision 3D displays based on polarizing arrays:
(1) The micro-image array comprises two groups of image elements, and the two groups of image elements are arranged at intervals in the horizontal and vertical directions.
(2) Both sets 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 picture elements are square and the horizontal pitch of the pinholes is equal to the vertical pitch.
(4) The polarization units corresponding to the picture elements are square, and the horizontal pitch of the polarization units 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 defects 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 the number of 3D pixels of a single 3D image in the integrated imaging 3D display. Thus, the uneven distribution of 3D pixels further affects the viewing effect.
(2) The horizontal viewing angle is much smaller than the vertical viewing angle.
For a cell phone, the ratio of the horizontal width to the vertical width of the cell phone is 3:4, 10:16, or 9:16. The defects 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 the number of 3D pixels of a single 3D image in the integrated imaging 3D display. Thus, the uneven distribution of 3D pixels further affects the viewing effect.
