This book investigates the principles and technologies behind glasses-free 3D displays, known as autostereoscopic displays. It covers fundamental concepts, including the parallax-barrier method, and progresses to advanced multi-view and multi-projection systems. The text also provides foundational knowledge on 2D display technologies, as their advancement influences 3D display development, and includes detailed explanations of techniques like the slanted lens method for those with prior expertise.

The book is structured to cater to a broad audience, from students beginning their study of display technologies to professionals already working in the field. Its comprehensive approach, starting with fundamentals and moving to advanced topics, suggests it serves as both an introductory text and a reference for current and emerging autostereoscopic technologies. The inclusion of both 2D and 3D display principles indicates a thorough grounding in the subject matter.
