A display device includes a glass pane, a display panel which is transmissive, and a glass panel unit. The display panel faces a prescribed area of the glass pane and is within the prescribed area. The glass panel unit is disposed between the prescribed area of the glass pane and the display panel and is within the prescribed area. The glass panel unit has an internal space which is in a pressure-reduced condition.

A mirror device includes: a mirror including a rotation shaft pivotably supported, a coupling shaft separated from the rotation shaft, and a reflecting surface that reflects display light; a coupling member including a first coupling portion coupled to the rotation shaft and a second coupling portion coupled to the coupling shaft, and configured to pivot integrally with the mirror; a motor that is connected to the coupling member via a gear and that pivots the coupling member; and a first spring having one end side immovably fixed and another end side coupled to the coupling member, and configured to apply force to the coupling member in one rotation direction.

A display device includes a circuit board including a first circuit portion, a second circuit portion, and a third circuit portion, a first display panel on the first circuit portion, and configured to emit a first light, a second display panel on the second circuit portion, and configured to emit a second light, a third display panel on the third circuit portion, and configured to emit a third light, and an optical combiner configured to combine the first light, the second light, and the third light to output a light.

A method for calculating an overlay of additional information for a display on a display unit, in particular, a head-up display of a transportation vehicle or data glasses. The overlay of additional information supports the driver in the longitudinal control of a transportation vehicle. The position of an upcoming waypoint is detected, which is specified by the navigation system. When the observer transportation vehicle approaches the waypoint, an animation graphic is calculated, wherein the animation graphic has a grid shape. The animation graphic is calculated so that distance markers are inserted from the observer transportation vehicle to the waypoint, which permit estimation of the distance to the waypoint.

A system for controlling a vehicle display based on an occupant's gaze includes: a first occupant gaze recognition unit to recognize a gaze of a first occupant in a vehicle; a second occupant gaze recognition unit to recognize a gaze of a second occupant in the vehicle; an interest information display area crossover confirmation and priority determination unit to determine interest information from the gaze of the first occupant and the gaze of the second occupant, to confirm whether areas for displaying interest information on a windshield are mutually crossover with each other, and to determine a priority for display; and a display control unit to control a display in accordance with the priority for display.

A switchable backlight for a switchable privacy display apparatus comprises a collimated waveguide and an optical turning film comprising first and second arrays of elongate prismatic elements. High image luminance and image visibility is provided for off-axis viewers in a public mode of operation while in a privacy mode of operation visual security level above a perceived privacy threshold may be achieved for off-axis snoopers.

A vehicle head-up display device may include a plurality of first image generation parts embedded in a vehicle body, and configured to provide flat and stereoscopic images in multiple directions, a first optical induction part configured to guide an image signal, provided by the first image generation parts, in one direction, and a first display part configured to implement the image signal, provided by the first optical induction part, as an image recognizable by a driver, thereby implementing augmented reality of a head-up display.

Provided are a content visualizing device and method that changes positions and shapes of route guidance content and driving related content based on a distance to an adjacent object, a current driving state, and an occurrence of a driving related event.

A reflectance/transmittance of an optical device disposed at a position through which image light emitted from a liquid crystal display displaying an icon passes is changed according to an anti-glare level to achieve anti-glare of the reflected image. A color of the icon displayed on the liquid crystal display is adjusted such that the higher the transmittance of the optical device is, the lower the lightness is, so that the icon of a similar color is visually recognized regardless of the reflectance/transmittance of the optical device.

A vehicle display system is disclosed. The system comprises an electro-optic device configured to switch between a mirror state and a light-transmissive state. The electro-optic device comprises a first substrate and a second substrate forming a cavity. The cavity is configured to retain an electro-optic medium that is variably transmissive such that the electro-optic device is operable between substantially clear and darkened states. The system further comprises a substantially transparent display disposed adjacent to the electro-optic device. The electro-optic device is converted to the darkened state when the substantially transparent display is emitting light.
