DISPLAY
First Claim
1. A display having a first multiple view mode of operation and a second single view mode of operation, comprising:
- a transmissive spatial light modulator arranged, in the first mode, to display a plurality of spatially multiplexed images for viewing in respective different viewing regions and, in the second mode, to display a single image for viewing in a single relatively large viewing region, the modulator having an input polariser arranged to pass light of a first polarisation; and
a backlight having a light output surface comprising first regions spaced apart by second regions and being electronically switchable between the first mode, in which only the first regions emit light containing the first polarisation, and the second mode, in which both the first and second regions emit light containing the first polarisation.

Abstract
A display is provided having a multiple view mode of operation and a wide angle single view mode. The display comprises a transmissive spatial light modulator which displays spatially multiplexed images in the multiple view mode and a single image with full resolution in the single view mode. The modulator has an input polariser which passes light of a first polarisation. A backlight has a light output surface with alternating first and second regions of parallel strip shape. The backlight is electronically switchable between the multiple view and single view modes. In the multiple view mode, only the first regions emit light containing the first polarisation. In the single view mode, both regions emit light containing the first polarisation.

7. A multiple view display comprising:
- a spatial light modulator comprising a plurality of pixels and being arranged to display N spatially multiplexed images simultaneously in each time frame of a cyclically repeating set of N time frames, where N is an integer greater than one, such that each pixel displays an image pixel of different ones of the images in different time frames of each set; and
a parallax optic cooperating with the modulator to make each of the N images visible in the same respective one of the N viewing regions during all of the time frames. - View Dependent Claims (8, 9, 10, 11, 12, 13, 36, 37)
