  • Patent number: 11874576
    Abstract: A switchable privacy display apparatus comprises a polarised output spatial light modulator, and an additional polariser. A reflective polariser, switchable liquid crystal polar control retarder, passive polar control retarders and air gap are arranged between the display output polariser and additional polariser. The passive retarders are arranged to provide no phase difference to polarised light from the spatial light modulator for on-axis light; and simultaneously provide a non-zero phase difference for polarised light in off-axis directions. The polar control retarders are further arranged to achieve low reflectivity for light propagating through the air gap. A switchable privacy display that can be conveniently assembled at low cost can be provided with high contrast images for display users while maintaining high visual security level for off-axis snoopers.

  • Patent number: 11874541
    Abstract: A switchable privacy display comprises an emissive SLM, a parallax barrier, a switchable LC retarder, and passive retarders arranged between parallel output polarisers. In privacy mode, on-axis light from the SLM is directed without loss, whereas the parallax barrier and retarder layers cooperate to increase the VSL to off-axis snoopers. The display may be rotated to achieve privacy operation in landscape and portrait orientations. In public mode, the LC retardance is adjusted so that off-axis luminance is increased so that the image visibility is increased for multiple users. The display may also switch between day-time and night-time operation, for example for use in an automotive environment. A low reflectivity emissive display for use in ambient illumination comprises a SLM with emissive pixels, an absorptive parallax barrier and a high spectral leakage optical isolator. Head-on light from the pixels is directed with increased transmission efficiency while ambient light is strongly absorbed.

  • Patent number: 11860339
    Abstract: The present invention provides an optically anisotropic layer which has a plurality of regions in which alignment states of a liquid crystal compound are different in a thickness direction and in which peeling is unlikely to occur in the layer. The optically anisotropic layer of the present invention is an optically anisotropic layer formed of a liquid crystal compound, in which the optically anisotropic layer contains a leveling agent and satisfies a predetermined requirement in a profile of a secondary ion intensity derived from the leveling agent in a depth direction, which is obtained by analyzing components of the optically anisotropic layer in a depth direction by time-of-flight secondary ion mass spectrometry while irradiating the optically anisotropic layer with an ion beam from one surface of the optically anisotropic layer to the other surface of the optically anisotropic layer.

  • Patent number: 11840130
    Abstract: A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The virtual visor system advantageously adopts a gradient blocking mode for the optical state of the visor that includes a blocker and a transition gradient, which has the effect of making updates to optical state of the visor less distracting. Additionally, the transition gradient in the optical state of the visor makes the virtual visor system more robust against errors in positioning the blocker on the visor.
