Abstract
Three dimensional display is the major effort toward natural vision in the development of display technology. Current 3D display suffers from the issues of low resolution and narrow viewing angle due to the availability of high performance key components, which results in low acceptability of 3D displays in the consumer market. In this research, a novel concept of constructing high resolution and wide viewing angle autostereoscopic 3D display by using proximity projector array has been proposed for solving the issue with currently available technology. A pixel size down to a few tens micro can be achieved by projecting microdisplay with low magnification ratio, and a large screen can be made by tiling up an array of such projected screen. Accompanying with slant lenticular array, it becomes possible to make a high resolution and wide viewing angle 3D displays. The major work of the research are the design and evaluation on the proximity projection optics, and optimization of slant lenticular array. In this research, the single proximity projection optics has been designed with the MTF value up to 32% at the spatial frequency of 64lp/mm and the greatest distortion value smaller than 0.1% which value is in between half to one pixel size. Besides to polarization beam splitter, all the lens are made of plastic optics materials, such as PC and COC, and therefore it can be potentially fabricated with low cost.
