Abstract

A vehicle indication system is proposed having an optical system ( 1 ), having a first indication device ( 2 ) and having a second indication device ( 3 ), wherein the optical system is intended to indicate information, which is provided by the first indication device, in an at least partially transparent or translucent form, wherein the optical system is intended to indicate information, which is provided by the second indication device, in an at least partially reflective form, wherein the optical system has a first area ( 6 ), the light transmission coefficient and light reflection coefficient of which are variable, and wherein the optical system has a second area ( 4 ), the light reflection coefficient of which is provided in a reduced form by means of a non-reflective layer.

Claims (11)

1. A vehicle display system comprising:

a first display device;

a second display device; and

an optical system configured to switch from being at least partially transparent or translucent to display information provided by the first display device to being at least partially reflective to display information provided by the second display device,

wherein the optical system includes:

an electrochromic first region including a light transmission and a light reflection coefficient that are changeable, wherein the electrochromic first region switches the optical system from being at least partially transparent or translucent to at least partially reflective,

a second region including a light reflection coefficient reduced by an antireflection layer; and

wherein the electrochromic first region is between a further layer that serves as a support layer and a layer, each of the further layer and the layer comprising a glass material.

2. The vehicle display system as claimed in claim 1 , wherein the optical system is substantially one of flat and planar design.

3. The vehicle display system as claimed in claim 1 , wherein the first display device is an analog display device, and wherein the second display device is a digital display device.

4. The vehicle display system as claimed in claim 1 , wherein the electrochromic first region is directly between the further layer that serves as the support layer and the layer.
