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 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.

Technologies and techniques for displaying information for an occupant of a motor vehicle. The display position of a head-up display is able to be varied flexibly depending on the context. To this end, both a displacement of the X and/or Y position and a color selection adapted to the background may be implemented and be performed automatically. Information from the steering angle, speed, map data and also head tracking by the interior camera may be combined to determine the X and/or Y position. In order to achieve optimum visibility for any load case, sensor fusion from the position data and an exterior camera may take place: Content or information (24) may thus be displayed depending on the current display position, so as to be more visible. If only some of the information is on a background, only some of the color may also change.

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.

The present invention relates to a vehicle display device comprising: a light synthesizer which reflects incident light to form a first image, transmits incident light to form a second image, and synthesizes the first and second images to form a synthesized image; at least one first display outputs an image to be reflected; at least one second display outputs an image to be transmitted; a position changer which moves at least one of the first and second displays in a direction close to or away from the light synthesizer; and a processor which controls the position changer to move at least one of the first and second displays such that, among the first and second images, one including a background image and the other including image information to be displayed overlappingly with the background image are away from or close to each other.
