Projection Displays (eBook)

Matthew S. Brennesholtz, Insight Media, Pleasantville, NY Dr Brennesholtz is currently a Senior Analyst at Insight Media in the USA. In this position, he works on a variety of topics relating to display systems, including supply chain issues, emerging display technologies and new applications for microdisplay technology. He has also headed research projects on illumination systems for projection displays, covering lasers and conventional lamps, and on a new type of liquid crystal on silicon (LCoS) backplane. In addition to this, he has authored 18 conference and journal papers, and the first edition of Projection Displays (Wiley, 1998) with Edward Stupp. Previous to his employment at Insight Media, Dr Brennesholtz has had positions at Philips and General Electric, and he currently holds 23 patents. Edward H. Stupp, Stupp Associates, Display Consultation, Jackson, NJ Edward Stupp currently runs his own consulting company, advising on display technology for industry. He authored the first edition of Projection Displays (Wiley, 1998) but is not directly contributing to the revision of the second edition. He will be listed as a co-author due to his involvement in the first edition.
