Abstract: A controllable privacy structure, such as a window or door, may include an electrically controllable optically active material connected to a driver. The driver can control the application and/or removal of electrical energy to the optically active material to transition from a scattering state in which visibility through the structure is inhibited to a transparent state in which visibility through the structure is comparatively clear. The driver may need to be located in relatively close physical proximity to the privacy structure the driver is intended to control. Devices, systems, and techniques are described for discretely positioning a driver relative to a privacy structure to be controlled.

Abstract: An electronic device such as a head-mounted device may have a display that produces a display image. The head-mounted device may have an optical system that merges real-world images from real-world objects with display images. The optical system provides the real-world images and display images to an eye box for viewing by a user. The optical system may use time interleaving techniques and/or polarization effects to merge real-world and display images. Switchable devices such as polarization switches and tunable lenses may be controlled in synchronization with frames of display images. Geometrical phase lenses may be used that exhibit different lens powers to different polarizations of light.

Abstract: A display device includes a pixel layer disposed on a base substrate, a first inorganic insulating layer disposed on the pixel layer, a first switch electrode disposed on the first inorganic insulating layer, a liquid crystal layer disposed on the first inorganic insulating layer and the first switch electrode, a second inorganic insulating layer disposed on the liquid crystal layer, and a second switch electrode disposed on the second inorganic insulating layer to face the first switch electrode. The liquid crystal layer converts light emitted from the pixel layer into about 90 degree linearly polarized light by an electric field formed between the first switch electrode and the second switch electrode in the private mode.

Abstract: The present invention is to enable avoidance of a reduction in external appearance quality, and stable driving, and prevent diffracted light from being discerned by avoiding a reduction in transmittance and a deterioration in liquid crystal alignment. A light control film is provided with: a first laminate in which an alignment layer is provided; a second laminate in which an alignment layer is provided; a liquid crystal layer which is sandwiched between the first and second laminates and contains liquid crystal molecules; a spacer disposed in the liquid crystal layer to hold the thickness of the liquid crystal layer; and electrodes provided in the first laminate and/or the second laminate, and controls transmitted light by controlling the alignment of the liquid crystal molecules driven by the electrodes. The proportion of an area occupied by the spacer per unit area in a light controllable-region of the liquid crystal layer is 0.1-10%.

Abstract: An electronic device has an electrically adjustable shutter. The shutter may be placed in a transparent state or a nontransparent state. The shutter may overlap a portion of a display, may overlap a liquid contact indictor or a structure with text in a device, or may overlap an optical component such as an optical proximity sensor, ambient light sensor, visible light-emitting diode or laser, infrared light-emitting diode or laser, visible light image sensor, or infrared light image sensor. Control circuitry in the electronic device may place the shutter in an opaque state to hide an overlapped component from view or may place the shutter in a transparent state to allow the overlapped component to transmit or receive light. The adjustable shutter may exhibit changes in its transmission spectrum in different modes of operation and may be used as a camera filter or neutral density filter.

Abstract: Systems and methods for guiding a vehicle occupant's attention are disclosed herein. One embodiment selects automatically a particular region of an environment external to a vehicle and guides an occupant of the vehicle to look at the particular region by automatically adjusting the transparency of one or more windows of the vehicle such that a first portion of the one or more windows through which the occupant is able to see the particular region is more transparent than a second portion of the one or more windows that is adjacent to the first portion.
