The disclosure relates to an optical waveguide for a display device and to a device for generating a virtual image using such an optical waveguide. The optical waveguide has two or more partial optical waveguides adapted to different wavelengths. At least one of the partial optical waveguides in this case has an optical filter. The optical filter is adapted to the wavelengths used.

Provided are a vehicle control apparatus and a control method thereof. The vehicle control apparatus includes a display device provided in a vehicle body, in which the display device includes a display including a first area, a second area and a third area to display visual information, a drive assembly configured to change at least one of a shape of the display and a position of the display, and a controller configured to control the display and the drive assembly, and in which the controller is further configured to control brief information displayed in the second area to be specified and displayed as detailed information in the first area or control detailed information displayed in the first area to be simplified and displayed as brief information in the second area.
