Projection Displays, Second Edition

Projection is a technology for generating large, high resolution images at a price point end users can afford. This allows it to be used in a wide variety of large-screen markets such as television and cinema. In addition, there are emerging small screen markets where a pocketable miniaturized projector can display images from mobile information devices such as smart phones or portable media players.

Fully revised, this second edition of Projection Displays provides up-to-date coverage of the optical and mechanical systems in electronic projection displays. It takes into account major new developments in the many technologies needed to manufacture a projector display system. It presents a comprehensive review of projector architectures, systems, components and devices. Key new and updated features include:

• new material on light sources for projection displays;
• updated information on the human factors of projection displays including color gamuts, resolution and speckle;
• coverage of new image generating systems including LCOS and scanned laser systems;
• up to date information on front and rear projection screens;
• practical examples of projection display applications;
• models for predicting the performance of optical and mechanical systems

This book is aimed at practicing engineers and researchers involved in the research, development, design and manufacture of projection displays. It includes key aspects from the many technologies contributing to projection systems such as illumination sources, optical design, electronics, semiconductor design, microdisplay systems and mechanical engineering. The book will also be of interest to graduate students taking courses in display technology and imaging science, as well as students of the many other engineering, physics and optics disciplines that lead into the field of projection displays.

About the Authors

Mr. Matthew Brennesholtz has worked in the display field since receiving his Masters of Engineering degree from Cornell University in 1978. He has worked on direct view CRT systems and projection systems based on CRTs, Talaria oil-film light valves, DMDs, LCDs and LCoS. In addition to system level development work, he was involved in the design and testing of optical components for projection systems. He helped develop both the imagers and the optical systems for the Philips single-panel LCoS system. He also has experience in the manufacturing of CRTs, Talaria and LCoS systems. Currently he is at Insight Media providing consulting and other services to the display industry. Mr. Brennesholtz is a Senior Member of the SID, plus a member of SMPTE and the SPIE.

Dr. Edward H. Stupp is a display consultant with nearly 30 years' experience in many display-related technologies, including projection and direct-view systems and components. Specific experience includes system architectures, single crystal Si-, polycrystalline Si- and amorphous Si-based microdisplays, liquid crystal materials and phenomena, cathode ray tube projectors and electrophoretic devices and systems. He was previously Department Head, Display Systems at Philips Research, Briarcliff Manor, NY. He is a Fellow of the SID.
