Abstract

This invention provides a display means such as a television or computer monitor which uses time sequenced addressing to physically segment user space into segments which each receive different respective full resolution image streams (or television programs). The display uses a pixel generation mechanism such as a DMD to generate a rapid succession of pixels which are rapidly swept across the user space using a variable deflector operating in rapid iterations in cooperation with the DMD. First frame pixels from a first program are directed to a first user space segment, first frame pixels from a second program are directed to a second user space segment, and so on until all first frames are sent to applicable use space segments. Then the second frame is sent to each respective user space segment, and so on iteratively. A positionally segmented image display enables multiple users to each see full resolution programs on the same display at the same time. Alternately, a positionally segmented image display enables multiple users to each a different full resolution view of the same 3D image on the same display at the same time.

Claims

1. An image display system for providing a first image to a first portion of user space and a second image to a second portion of user space wherein a user in the first portion of space can see the first image but can not see the second image and wherein time sequencing is used to direct images to each respective user space.
