AI Technical Summary

Problems solved by technology

However, displays (such as LCDs) with pixels that radiate as an extended light source and have a wide pattern do not generally provide collimation of the beam
Therefore, it is problematic to use (utilize) such pixel-radiative displays in time-sequential 3D display devices using known optical imaging systems

Abstract

An optical imaging system and related 3D display apparatus for forming different perspective views of a 3-dimensional image by transforming optical beams emanating from pixels located on a display pixel surface displaying 2-dimensional patterns and projecting the transformed optical beams in a field of view is disclosed herein. The optical imaging system comprises: an array of selecting light guide elements for reducing a radiating aperture of each pixel; a lens array of converging micro-lenses; a displacement mechanism for moving the lens array relative to the array of light guide elements in a respective plane; and a sensor system for sensing the position of the lens array relative to the array of light guide elements. The lens array together with the array of light guide elements are configured to provide at least one viewing zone in the field of view and form respective perspective views in each viewing zone by projecting therein the transformed optical beams.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 586,809, filed January 15, 2012, the entire contents of which application are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates generally to a time-sequential autostereoscopic display system, and more particularly to an optical imaging system and 3D display device utilizing the system to form a perspective view of a three-dimensional (3D) image of an object or scene. The invention is useful for displays (such as LCDs) with pixels that radiate as extended light sources and have wide directional diagrams. Background technique [0004] An advantage of a time-sequential autostereoscopic display system over a space-sequential autostereoscopic display system is that a time-sequential autostereoscopic display system provides high resolution of the 3D image regardless of the number of perspective views ...
