摘要
介绍DLP背投电视机的基本原理与结构,以及基于笔记本电脑平台和DVD播放机、SpyderTV套件调校DLP背投电视机的方法;包括调校前的基本设定以及精确地检测DLP背投电视机投影画面的色温、亮度、对比度、色饱和度等光度特性,并指导调整,从而显著地改善投影画质。并对单片式DLP背投电视机特有缺陷"彩虹效应"的判断进行了探索。研究表明,使用该方案具有很高的可靠性与易用性,依据观赏环境把DLP背投电视机调整到最优化的设定值,使DLP背投电视机发挥它的最佳性能。
The basic principle and structure of DLP rear projection TV and the methods of modulating DLP rear projection TV based on notebook computer, DVD player and SpyderTV software＇s are introduced. The methods include the fundamental assume setting before modulation, testing precisely and guiding the adjustment of the optical characteristics such as color temperature, bright, contrast and chromaticity. Furthermore, the methods of testing the special fault ＇Rainbow Effect＇ of singlechip DLP rear projection TV are analyzed. Research indicates that the methods have better reliability and availability, and can adjust the picture quality of DLP rear projection TV to highest level according to the visible environments.
