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 [start italics]Projection Displays[end italics] 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.read more

Analysis of color profile quality of digital projector
Iva Molek,Dejana Javoršek +1 more
TL;DR: Javorsek et al. as discussed by the authors analyzed the display of colors in digital projection using an eye-one spectrophotometer and showed that a digital projection displaying standardized sRGB color space could not be comparable to a high quality CRT or LCD computer screen.
Patent
Optical system for image projectors
TL;DR: In this article, a projector system consisting of a laser light source, a collimating lens, a fly-eye lens, an integrating rod and a first modulator is described, where the light from a laser source/fiber illuminates a collimator to substantially collimate the light and then is transmitted through a fly's eye lens.
