摘要

隨著時代科技的進步，投影顯示器不論在商用會議、家用電視或是大尺寸的用途，都是具有一定的市佔率，但是傳統投影機光源的壽命、體積及色彩，都是令人垢病的地方，所以本論文提出一個新型投影顯示器光源，具有壽命長、色彩豐富、效率高、體積小及均勻度佳的投影顯示器光源，在目前都是微小化的時代，具有一定優勢。
本論文介紹及比較目前常見的四種投影顯示器，挑出數位微鏡式投影顯示器當做設計目標，且針對數位微鏡式投影顯示器的架構做比較，設計雷射投影機光源系統，建構在全內反射式稜鏡式數位微鏡投影顯示器內，並且跟傳統燈泡光源在傳統的投影顯示器架構下作比較，所設計出的光源系統，具有73.55％系統效率、99.3％的ANSI Uniformity和131％的NTSC面積大小(在CIE1931系統下)，雖然在光展量匹配上有很大的損耗，不過這是在傳統投影機架構下，若未來將投影機微小化時，情況將會被改善。

With the progress of science and technology of the times, the projection display is no matter at commercial meeting, home theater or larger use; all have certain taking rate of market. But the traditional projector has some defects which are life-time and color. So we propose a novel projection light source of display in this paper, has long life-time, color, high efficiency and high performance of uniformity in the projection display. In the microfabrication the times, that will be an advantage.
We introduced and compared the four types of projector and regard as our design in the digital micro-mirror device type of the projector, this is called DLP. We design the illumination system with new light source which is built in digital micro-mirror device projection display of TIR prism type and compare the traditional lamp light source and laser light source system with the same projector structure in this paper. Our system has 73.55% of the system efficiency, 99.3% of the ANSI Uniformity and 131% of the NTSC area (under CIE1931 system). We have loss in the Étendue matched but that based on convention structure of projector. If we reduce the size of projector in the future, that defect will be reformed.
