A new optical lithography method for fabricating humpbacked pattern arrays was developed. The patterns were printed by adopting intentionally defocused projection exposure under the condition of very low numerical aperture of 0.089. As a resist, approximately 100-µm thick SU-8 (MicroChem) was used, and appropriate defocuses were 1400-2000 µm. When the exposure time and the defocus were changed, curvature radiuses of lens patterns were controllable in a wide range of 70-300 µm. The curvature radii became large when the exposure time was extended, and the defocus was reduced. The patterns will be usable as original molds of lenticular lens arrays. In addition, the patterns will also be usable as temporal lenticular lens arrays as they are, because the SU-8 is almost transparent for visible light.

“…On the other hand, for autostereoscopic multi-view 3D display, the parallax barrier and lenticular lens approaches which mainly employ the spatially multiplexing concept, are the commonly used methods. For lenticular lens approach, the current market requirement is how to let viewers have the capability to change the focal length of the lenticular lens [5,6], adjust the lens pitch, and real-time switch the 2D/3D modes [7][8][9][10]. At present, the autostereoscopic display technologies have common limitations like the fixed range of the viewing distance, view position, and the fixed IPD value (usually 65mm).…”

“…Because there is an extremely large calculation demand in sub-pixel allocating, masks are usually pre-made containing allocated sub-pixels suitable for the barriers front for each viewpoint, and manipulated with parallax frames indirectly arranging their sub-pixels to obtain a real-time stereoscopic image [1], [2] . Therefore mainly computation in these real-time displaying steps turns into the operation between masks and parallax frames.…”

With the progress of 3D technology, the huge computing capacity for the real-time autostereoscopic display is required. Because of complicated sub-pixel allocating, masks providing arranged sub-pixels are fabricated to reduce real-time computation. However, the binary mask has inherent drawbacks. In order to solve these problems, weighted masks are used in displaying based on partial sub-pixel. Nevertheless, the corresponding computations will be tremendously growing and unbearable for CPU. To improve calculating speed, Graphics Processing Unit (GPU) processing with parallel computing ability is adopted. Here the principle of partial sub-pixel is presented, and the texture array of Direct3D 10 is used to increase the number of computable textures. When dealing with a HD display and multi-viewpoints, a low level GPU is still able to permit a fluent real time displaying, while the performance of high level CPU is really not acceptable. Meanwhile, after using texture array, the performance of D3D10 could be double, and sometimes be triple faster than D3D9. There are several distinguishing features for the proposed method, such as the good portability, less overhead and good stability. The GPU display system could also be used for the future Ultra HD autostereoscopic display.
