Abstract:
A privacy display comprises a polarised output spatial light modulator, reflective polariser, switchable liquid crystal retarder and polariser. 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. Further, display reflectivity is reduced for on-axis reflections of ambient light, while reflectivity is increased for off-axis light. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction and increased frontal reflectivity to ambient light. In a wide angle mode of operation, the liquid crystal retardance is adjusted so that off-axis luminance and reflectivity are unmodified.

Claim (Index 25):
A switchable display device according to  claim 24 , wherein the collimating waveguide comprises\n (i) a plurality of elongate lenticular elements; and (ii) a plurality of inclined light extraction features, wherein the plurality of elongate lenticular elements and the plurality of inclined light extraction features are oriented to deflect input light guided through the directional waveguide to exit through the first guide surface.
