Abstract:
A privacy display comprises a spatial light modulator and a compensated switchable liquid crystal retarder arranged between first and second polarisers arranged in series with the spatial light modulator. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction over a wide polar field. In a wide angle mode of operation, the switchable liquid crystal retardance is adjusted so that off-axis luminance is substantially unmodified.

Claim (Index 3):
A switchable display device according to  claim 1 , wherein the at least one passive compensation retarder comprises a pair of passive retarders have optical axes that are crossed and extend at 45\u00b0 and at 135\u00b0, respectively, with respect to an electric vector transmission direction that is parallel to the electric vector transmission of the display polariser.
