Liquid Crystal Display (LCD) projection technology has, in recent years, led the way in large area displays because of its potential to deliver scalable, high resolution images at a low cost. Since large displayed images demand high brightness and contrast, a full understanding of polarization, and how to manage its effects, is essential for the development of quality systems. Using the example of LCD projection technology, this practical text provides a thorough coverage of polarization engineering problems, with appropriate solutions and mathematical tools for analysis. Key features include: a comprehensive introduction to the basics of polarization, LCDs, projection technologies and LCD projection system engineering; a detailed examination of optical system components, including polarizers and retarder stack filters; a full treatment of system contrast and color management issues; and, in depth analyses of how to manage polarization in the major LCD projection systems. Display engineers, scientists and technicians active in this field will find this a valuable resource, as will developers of large screen projection displays and microdisplays. It is also useful for graduate students and researchers as an accessible introduction to the technology.
