    Abstract: A privacy display comprises a spatial light modulator and a compensated switchable guest-host 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.

  • Patent number: 11249350
    Abstract: Method of forming and patterning in situ on a film component of a layer of spacer structure material to define spacer structures in at least active areas of a liquid crystal (LC) cell array. Applying counter component to the film component after dispensing sealant material onto one or more of the components in areas around each active area of the array, and after dispensing one or more drops of LC material onto one or more of the components in each active area of the array. The components are pressed together to spread the drops of LC material over the active areas so the sealant material for each LC cell interfaces with the LC material for the respective LC cell. Each deposition area has an inner perimeter, which is controllably varied across the array to compensate for variations in one or more properties of the spacer structures across the array.
