近年微型顯示器(Micro Display)發展蓬勃，尤其是以微機電(MEMS)技術的數位光學處理器(Digital Light Processor， DLP)倍受青睞。本篇論文研究單片式數位光學處理器(One chip DLP)投影系統中顏色處理技術及改善的方法。在單片式數位光學處理器投影系統中，係將投射燈產生的光線經由色輪(Color Wheel)將紅，綠，藍三原色循序分離出來，以數位光學處理器同步成像;再因視覺暫留而重組彩色畫面。由於現有系統的超高壓投射燈紅光頻譜多很弱，往往造成投影畫面純紅色彩不足。針對這個缺點，本論文嚐試以調整投射燈驅動器的暫態輸出功率，強化通過色輪的紅光能量。期以最少的時間及資源而得到最佳化的顏色設計結果。

　　首先吾人探討投射燈驅動器工作原理及紅光強化的理論，根據此理論以數位光學處理器應用軟體COMPOSER進行模擬。然後進行紅色強化投射燈驅動系統的設計及驗證。經比對實際測驗結果，證實本設計確實可行;能有效強化紅光輸出及提昇單片式數位光學處理器投影系統的顏色性能表現。

　　Recently, micro display systems, especially, the Digital Light Processor (DLP) developed by TI based on MEMS technology, have been developed successfully for video projection applications. For the application, the color manage system is the key technology and has been studied extensively. In general, red, green and blue-three colors are separated sequentially, as the output light of projection lamp passes through color wheel in one chip DLP projector. Then the three colors are managed to generate a color image by the synchronized Digital Light Processor. However, due to the inherent weak intensity of red light in the color spectrum of conventional projection lamp, result in the degraded red color performance. In this thesis, we try to enhance the red color by only setting parameters of firmware in projection lamp driver and to optimize the color design with less cost and developing time.

　　Firstly, we study the operation principle of general projection lamp driver and develop the mechanism of red color enhanced projection lamp driver. Then use the DLP Composer to simulate and modify the mechanism. Finally, design and test the red color enhanced projection lamp driver system. Experimental results evidence the developed lamp driver not only possesses the higher output of red color and improves the color performance of projection system, but also is feasible for real application in color separate projector.
