Abstract
A display device and to transport having a display device of this type. The display device has an image-forming unit for generating an image and an optical unit for projecting the image using a mirror unit. The image-forming unit has a folding mirror, which is arranged between a light source and a display element transilluminated by the light from the light source. The folding mirror has microstructures having first mirror surfaces, which are arranged at a first angle relative to a direction of propagation of the light and are spaced apart from one another to form gaps. Second surfaces are arranged in the gaps, at a second angle relative to the direction of propagation of the light. The width of the gaps varies over a surface of the folding mirror.

A display device, comprising:
- an image-forming unit configured to generate an image, comprising:
- a folding mirror arranged between a light source and a display element that is transilluminated by a light of the light source, wherein the light that is incident on the folding mirror is collimated,
- wherein the folding mirror has microstructures having:
- first mirror surfaces that always have a same orientation and extent, which are arranged at a first angle relative to a direction of propagation of the light and are spaced apart from one another so as to form gaps;
- and
- second surfaces at a second angle relative to the direction of propagation of the light and are arranged in the gaps,
- wherein a width of the gaps varies over a surface of the folding mirror;
- and
- an optical unit configured to project the image by a mirror unit.
A transport comprising:
- a display device, comprising:
- an image-forming unit configured to generate an image, comprising:
- a folding mirror arranged between a light source and a display element that is transilluminated by a light of the light source, wherein the light that is incident on the folding mirror is collimated,
- wherein the folding mirror has microstructures having:
- first mirror surfaces that always have a same orientation and extent, which are arranged at a first angle relative to a direction of propagation of the light and are spaced apart from one another so as to form gaps;
- and
- second surfaces at a second angle relative to the direction of propagation of the light and are arranged in the gaps,
- wherein a width of the gaps varies over a surface of the folding mirror;
- and
- an optical unit configured to project the image by a mirror unit.
