摘要
隨著科技發達，行動通訊普及，影音娛樂的電子產品需求大增。從以前的隨身聽，變成現在可以隨身觀看影音的MP4、隨時上網的手機等等，加上商務上的需求，筆記型電腦需求大增。但由於這些電子產品大多提供畫面於個人使用，必須外加投影機才能供眾人一起看到畫面。本論文提出整合前投影以及背投影的雙模投影系統以便於達到以上所要的目的。 本論文將探討微型投影機的模擬設計並應用於可攜式元件的雙模投影，投影機設計分別探討其照明及成像兩部分，照明部分利用非序列性的光學模擬軟體做模擬分析，主要是模擬分析並設計出一個光學架構，將RGGB 四個chip的二極體Lambertian光源收入一微型顯示器。成像部份，則是利用序列性的光學模擬軟體，根據微型顯示器的規格，設計一組投影鏡頭將影像投影出去。並作系統整合成雙模投影。 並且本論文將提出兩種不同的方法來達成雙模投影顯示系統，希望藉投影的方式為單一影像源達到可攜式產品個人使用及眾人觀看畫面的目標。

The portable electronic products become more and more popular, because people can use these products for Video Entertainment and Business everywhere. The consumers can only receive the information from display images themselves. To share the image, they have to set up another projection device. This thesis proposes dual-mode projection display system to solve the aforementioned issue. This thesis will discuss the design of pico-projector applied in dual-mode projection display system. There are two parts in the design of pico-projector, one part of illumination use the non-sequential optical software for optimization. The other is the design of projection lenses. And then integrate the front projection and rear projection into dual-mode projection display system. This thesis will propose two methods to achieve dual-mode projection display, and discuss them respectively.
