Lumens and contrast ratio in relation to the Digital Micromirror Device [tm]

Image improvement is of major concern for all projection devices. The Digital Micromirror Device (DMD) has dominated image quality since its introduction just a few years ago. The competition is starting to match the lumens and contrast outputs of this device. In order for the DMD to maintain a competitive advantage, the lumens and contrast ratios have to improve. The thesis covers some aspects of the DMD that are open to change to improve the lumens and contrast ratio. The goal of the project was to see what parameters are really affecting lumens and contrast ratio and to possibly develop an equation that would model future predictions. This was done by using a design of experiments and analyzing the data using several methods. Hopefully, the information will be useful to future decisions about improving lumens and contrast ratio
