A method to realize arbitrary views for the lenticular lens array based on autostereoscopic three-dimensional display system is demonstrated. Normally, the number of views is proportional to pitch of the lenticular lens array. Increasing the number of views will result in reducing resolution and enhancing of granular sensation. 32 dense views can be achieved with one lenticular lens pitch covering 5.333 sub-pixels, which does significantly increases the number of views without affecting the resolution. But the structure of pitch and the number of views are fixed. Here, the 3D display method that the number of views can be changed artificially for most structures of lenticular lens is presented. Compared with the previous 32 views display method, the smoothness of motion parallex and the display depth of field are significantly improved.
A lenticular-type super multi-view (SMV) display method with narrow structure pitch and small light intensity ripple is presented. Normally, increasing the number of viewing zones can reduce the amplitude of the light intensity ripple. The viewing zones’ number is proportional to the structure pitch of the lenticular lens array. However, wide structure pitch will decrease the spatial display resolution. Here, a lenticular lens array with one pitch covering 2.2 sub-pixels and novel arrangement of left and right sub-pixels groups are designed. The proposed display method can provide twenty-two viewing zones. By the introduction of tracking device, both binocular parallax and motion parallax are experienced. By measuring with the photometer, the light intensity ripple is 0.7%, which is far smaller than the traditional SMV display with 8 viewing zones. As the fluctuation of light intensity is reduced, the 3D perception effect is improved.
