Data on Display Technology Detailed by Researchers at Fuzhou University

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Display Technology. According to news reporting out of Fuzhou, People's Republic of China, by VerticalNews editors, research stated, "Common projection optics use Kohler illumination to achieve a required lighting. These systems always prevent the realization of a compact optical configuration along with a high lumen output."

Our news journalists obtained a quote from the research from Fuzhou University, "Based on conventional Kohler illumination, a modified Kohler illumination system for LED-based projection display is presented in this paper, which can significantly reduce the system volume while allowing for adequate and homogeneous illumination. Equipped with the proposed system, a pocket-sized CF-LCoS projector with a physical dimension of 27.4 mm x 19.4 mm x 9.6 mm is designed, simulated and analyzed. Compared to conventional approaches, this design could offer an average 43% volume reduction with acceptable tolerance."

According to the news editors, the research concluded: "To the best of our knowledge, the screen uniformity of 90.2% and the light efficiency of 56.5% are competitive as compared with those of the currently commercialized pocket-sized CF-LCoS projectors."
