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

1. A vehicle display system (10) having an optical system (1), having a first display device (2) and having a second display device (3), wherein the optical system (1) is provided in an at least partially transparent or translucent fashion for the purpose of displaying information provided by the first display device (2), in that the optical system (1) is provided at least partially in a reflecting fashion for the purpose of displaying information provided by the second display device (3), the optical system (1) having a first region (6) whose light transmission and light reflection coefficient is changeable, and the optical system (1) having a second region (4) whose light reflection coefficient is provided in a fashion reduced by means of an antireflection layer.

2. The vehicle display system (10) as claimed in claim 1, wherein the optical system (1) has a transparent element, in particular a glass element, between the first region (6) and the second region (4).

3. The vehicle display system (10) as claimed in claim 1, wherein the optical system (1) is of substantially flat or planar design.

4. The vehicle display system (10) as claimed in claim 1, wherein the first display device (2) is provided as an analog display device, and in that the second display device (3) is provided as a digital display device.

5. The vehicle display system (10) as claimed in claim 1, wherein the optical system (1) has an electrochromic region in the first region (6).

6. The vehicle display system (10) as claimed in claim 1, wherein the optical system (1) has the electrochromic first region (6) between a further layer (7), as support layer, and a layer (5) made respectively from a glass material.
