| Summary: | 碩士 === 國立交通大學 === 光電工程學系 === 98 === Recently, many researchers invest in developing 3D display technology to produce more natural images from displays. Since most of display applications use the fixed optical components to display 3D images, the 2D images cannot be provided by the same displays. Thus, a 2D/3D switchable display is needed.
In this thesis, we designed an optical component which was driven by low operating voltage and can switch between 2D and 3D modes within a fast rate. In simulation, an optimized structure was designed to fit the Fresnel lens-like distribution to reduce the cell gap and achieve a fast switching rate. In experiment, the measurement result indicated that the Fresnel lens-like distribution and a fast switching rate (less than 1s) without using over-drive method were both achieved. Besides, with over-drive method, the switching time could be reduced to 0.2s, which was much shorter than the conventional structures (~ 4~10s). Moreover, the operating voltage (~5volts) was much lower than the conventional structures (~30volts).
In conclusion, the 3D display with the proposed structure not only has effective focusing ability and low operating voltage, but fast switching rate.
