An instrument panel for a motor vehicle is provided. The instrument panel includes an instrument panel surface and a plurality of indicia disposed on the instrument panel surface. The plurality of indicia comprises holographic ink.

An image display device includes a light source, a scanner, a screen, a virtual image optical system and a screen incident angle correcting optical system. The light source emits laser light. The scanner scans the laser light. An image is formed on the screen by the scanned laser light. The virtual image optical system generates a virtual image of the image by the laser light having transmitted through the screen. The screen incident angle correcting optical system orients the scanned laser light toward the screen. The scanner performs at least first scanning and second scanning that has a scanning direction different from a scanning direction of the first scanning. The screen includes a lenticular lens having a lens pitch in a direction parallel to the first scanning.

Indication systems for the drivers of vehicles and cars include a data display device that combines two optical systems of the image displaythe virtual image display system and the real image display system. The display device may be configured to provide a maximum of displayed information and to ensure safe driving, by controlling the level of details and the content of the data displayed for the vehicle driver, depending on the speed, and by choosing the optical system of data display to minimize the accident risk. Image quality and safe driving may be improved due to the combination of two systems and control of the level of detail of displayed data.

A vehicle display system displays information on a road surface. The vehicle display system includes an other-entity detector, an intersection detector, and a display device. The other-entity detector detects whether or not another entity approaches a vehicle mounted with the vehicle display system. The intersection detector detects whether or not the vehicle approaches an intersection. When the other-entity detector detects that said another entity approaches the vehicle or when the intersection detector detects that the vehicle approaches the intersection, the display device displays a predetermined shape in a predetermined region of a road surface ahead of the vehicle while moving the predetermined shape.

There is provided a system of displaying an augmented reality (AR) image on a viewable surface of a vehicle, the system comprising a processing circuitry configured to: receive data indicative of a location of a target external to the vehicle; determine a line-of-sight to the target in accordance with, at least, an operator viewing position and an operator viewing orientation; and control a scanning projector to display the AR image on a location of the viewable surface that is located substantially along the line-of-sight.
