本論文提出一種創新的裸眼立體顯示器，係利用微稜鏡光學膜貼附於液晶面板上層，以實現明暗式裸眼立體顯示器。首先，在實驗設計中，選取2.4吋TFT面板作為基材面板的模擬實驗參數，經過初階設計與應用光學模擬軟體LightTools進行光線追跡；完成光跡模擬後，實際將微稜鏡光學膜貼附於面板上進行明暗視覺分析。從實驗結果得知雙眼影像亮度對比達1.17，並造成9毫秒的雙眼視覺延遲，如此一來，已達到文獻所指出觀賞者可感受到的立體感；另外，相較於傳統裸眼立體顯示技術，明暗式裸眼立體顯示技術具有將平面影像直接產生立體感、影像解析度高、光學元件不需要對位、無串音干擾甚至無觀看得不適與疲勞的問題現象。

An innovative autostereoscopic display, in which a micro-prism sheet is placed on the upper layer of the liquid crystal panel, is proposed to implement the Pulfrich autostereoscopic display. A 2.4” TFT panel is selected as the experimental parameter of the substrate panel. After the preliminary design, LightTools is utilized for ray tracing, and the designed micro-prism sheet is placed on the upper layer of the liquid crystal panel for the shading visual analysis. The experimental results show that the binocular image contrast between the bright image and the dark image on the Pulfrich autostereoscopic display achieves 1.17, allowing the viewer perceiving the stereoscopic perception, and the visual lag lasts for 9ms. Furthermore, The Pulfrich autostereoscopic display, in comparison with traditional autostereoscopic displays, presents the advantages of stereoscopic perception on plane images, high image resolution, and the optical element without counterpoint, crosstalk, and stereoscopic pairs to cause discomfort and fatigue.
