Partitionable display system
First Claim
1. An apparatus for displaying images on a liquid crystal display having partitionable selectively visible regions, comprising:
- first polarizing means for forming planer polarized light background from incident light;
a liquid crystal display panel for forming images cross-polarized with polarized light background in substantially parallel alignment with said first polarizing means having a front side displaying said images;
moveable polarizing means for selectively covering at least a region of liquid crystal display panel, disposed in substantially parallel alignment with said liquid crystal display panel, disposed at the front side of said liquid crystal display panel, opposite said first polarizing means;
remote polarizing means disposed away from said liquid crystal display having polarization relative to said movable polarizing means which is one of planar-polarization or cross-polarization;
said remote polarization means operative for enabling a viewer looking through said remote polarizing means to view said images both covered and uncovered by said movable polarizing means; and
wherein said regions uncovered by said movable polarizing means are invisible for viewing without said remote polarizing means;
moving means connected to said movable polarizing means for displacing said movable polarizing means.

Abstract
An apparatus to display images with partitionable regions allowing visible, invisible, and narrow field of view of displayed information includes a polarizing means to form a plane polarized light background from incident light, a liquid crystal panel capable of forming cross-polarized images against a plane polarized background, and a proximal movable polarizing means to distinguish images on liquid crystal panel from its plane polarized background. Linear translation of the movable polarizer partitions the liquid crystal panel into regions that are visible where there is optical alignment of the liquid crystal panel, background polarizer, and movable cross-polarizer. An optional remote polarizer complements the movable polarizer and provides a narrow viewing angle of images not visible on the liquid crystal panel. By creating a user defined visible, invisible, and narrow field of view of displayed information on an LCD assembly, electronic devices incorporating such a display can be made to provide computing privacy, accessibility to the device, strategic information separation, and information separation to multiple users.

16. An apparatus for displaying images having partitionable regions, including selectively visible and invisible regions of displayed information comprising:
-
polarizing means for forming a plane-polarized light background from incident light; a liquid crystal panel for forming cross-polarized images in parallel alignment with said plane-polarized background; movable polarizing means for selectively distinguishing at least one of said images on said liquid crystal panel from said plane-polarized background by cross-polarization of one of said images or by cross-polarization of said background, including linear translation means connected to said polarizing means for forming partitions on said liquid crystal panel into regions that are visible where there is optical alignment of said liquid crystal panel with said background polarizing means, and with said movable polarizing means; retaining means for retaining alignment of said movable polarizing means in linear movement of said movable polarizing means; and
translation means connected to said movable polarizing means for providing linear displacement of said movable polarizing means. - View Dependent Claims (17, 18, 19, 20, 21)
