    Abstract: 摘要 為了因應數位視訊時代、運用網際網路與資訊世界溝通,並提供大尺寸、畫質清晰、性能優異的影音產品,是未來影像娛樂與廣播事業與消費者之間最重要的橋樑。在目前大尺寸顯示器的激烈競爭中,投影顯示器以其優越性能與最符合消費大眾之需求,被視為未來數位電視的明日之星。在投影顯示技術中,整合光學、機構、電子、熱流之系統整合,充分展現其技術之複雜性與挑戰性。 本文的研究在於創新一種有別於以往側投影顯示器的機箱架構,使其能不只具有傳統側投影顯示器的優越條件外,還有效的縮減投影顯示器的機箱厚度,使機箱的厚度尺寸(19公分)比傳統的側投影顯示器 (35公分) 薄了約40%以上。 A new technique, which based on polarization optics application, can be used to reduce the depth of the rear projection display housing. In traditional, the light path of the projection image in the display housing was using two mirrors to reduce the dimension of it. In traditional method, the light path cannot pass through or reflect from the screen before the focus plan. Beside, the view angle of the projection lens cannot be increased unlimited. So, the depth of the display housing cannot be reduced efficiently in traditional structure. In this research, we will create a new structure, which based on polarization optics method to reduce the rear projection display housing efficiently. The depth of the display housing can be reduced from 35 cm in traditional structure to 19 cm in new structure. It will be reduced at least 40%. It will be a great help to reduce the current rear projection display housing. In the last chapter, we will also use a new technique, which based on the moiré technique and wavelet transform to do auto alignment for R/G/B panels. This technique is also a real time, online inspection and economic technique for align the R/G/B panels in LCD projector production line.
