3D Light-Field Display Technologies

Abstract

We describe an advanced technique for implementing glasses-free three-dimensional (3D) displays, namely the light-field display. We explain why 3D displays need to control many more pixels than two-dimensional displays with the same resolution, and thus have more processing and light modulation capabilities. We discuss the rationale and design considerations for scalable light-field displays, the relationships and trade-offs between image resolution, field of view, field of depth, and horizontal and vertical motion parallax, as well as describe the current implementations and future research directions. Content creation methods for these 3D displays are also described. The chapter closes with a discussion of the requirements for creating the "perfect" 3D display of the future. © 2013 by John Wiley & Sons, Ltd.
