The ratio between number of image primitive is 9:16,10:16 or 3:4 in the number and vertical direction of image primitive on direction.Its shortcoming is that:
(1) the ratio between the 3D pixel in horizontal direction and the 3D pixel in vertical direction are 9:16,10:16 or 3:4.Since 3D schemes
The 3D pixel total amount of picture is not high, therefore the 3D pixel in horizontal direction is very few, to affect viewing effect.
In addition, in traditional integration imaging 3D display based on gradual-change bore diameter pinhole array, horizontal and vertical viewing view
Number of the angle respectively with image primitive in micro- pattern matrix is inversely proportional.
