Radar-Compatible External Display Device for a Vehicle

A radar-compatible external display device for a vehicle includes a display element for producing a light display external to the vehicle. The display element is disposed in the beam path of a radar system of the vehicle. Each pixel of the display element includes a transparent diffuser assembly and an electrically controllable light source or a deflecting element. Linear dimensions of the display light sources/deflecting elements are several times smaller than a predefined radar wavelength used in the radar system, while distances between adjacent light sources/deflecting elements are greater than said radar wavelength. As a result, radar radiation of the radar system of the vehicle propagates through the display element undisturbed.
