1. A display device for a vehicle, comprising:
- a display unit to emit a luminous depiction of variable image information including at least one of a text and a symbol, wherein the display unit includes a projection display unit;
a display layer, including a back surface and a front surface, to receive the luminous variable image information depiction at the back surface and to display the luminous variable image information depiction on the front surface, wherein the display layer includes a touch-sensitive surface adapted to generate electrical signals indicating a position where a user touches the front surface, and wherein the projection display unit is adapted to project the luminous variable image information depiction on the back surface of the display layer;
a light guide, comprising a fiber optic light pipe having a first surface and a second surface, to guide light received at the first surface to the second surface, with the first surface mounted on the front surface of the display layer to receive at least a part of the luminous variable image information depiction, wherein the light guide is fitted through a cavity that extends through the back surface of the display layer such that the light guide is illuminated by the projection display unit; and
a control knob mounted on the front surface of the display layer, the light guide arranged in the control knob, the second surface of the light guide being exposed at a surface of the control knob.

17. A method of displaying variable image information in a vehicle, comprising:
-
emitting light depicting variable image information including at least one of a text and a symbol with a projection display unit, wherein the projection display unit projects the emitted light on a back surface of a display layer; transferring the emitted light from the back surface of the display layer to a front surface of the display layer, wherein the display layer includes a touch-sensitive surface adapted to generate electrical signals indicating a position where a user touches the front surface; and guiding the transferred light, using a fiber optic light pipe having a first surface mounted on the front surface of the display layer, to a second surface of the fiber optic light pipe, wherein a control knob is mounted on the front surface of the display layer, the fiber optic light pipe is arranged in the control knob, and the second surface of the fiber optic light pipe is exposed at a surface of the control knob, and wherein the fiber optic light pipe is fitted through a cavity that extends through the back surface of the display layer such that fiber optic light pipe is illuminated by the projection display unit. - View Dependent Claims (19)
