  • Imaging equipment vacuum fluorescence displays and organic light-emitting LEDs known. Disadvantage of the head-up displays with liquid crystal display is the poor contrast ratio between the displayed information and the image background. Disadvantage of the head-up displays with Vaku ⁇ umfluoreszenzdisplay or organic light-emitting diode are their low overall brightness and their low Auf ⁇ solution.

  • a dot matrix is achieved, wherein, depending on the position of the micromirrors, the light from the light source reaches or does not reach the combiner via the individual micromirrors. So a very strong contrast is achievable.
  • the field with the movable micromirrors can, for example, have 800 rows each with 480 micromirrors arranged next to one another.
  • a dot matrix can be reached whose number of points corresponds to the number of micromirrors.

  • the contrast should not be so extreme in individual cases, it is possible, for example, to change the individual pixels several times depending on the desired brightness in the position, so that the light of the individual pixels in the time course only partially reaches the combiner and thus the brightness lower fails.

  • the light source is particularly simple when it emits monochrome light of a color. But then only a monochrome representation is possible. If the light source emits monochrome light of different colors sequentially, multicolor display is possible. Here, the available colors are successively sent to the micromirrors one after the other. The human eye superimposes these individual colors when the change between the individual colors is faster than the resolving power of the human eye.
  • an aforementioned light source is a light source, which sends different colored light via alternating color filters of different colors. As a result, only one light source is required, but also additional different color filters.
  • an adjustable mirror is arranged in the beam path between the imaging device and the combiner, so that the position of the virtual image and the perception can be changed ness of head-up displays, which at ⁇ adjustment to different sized driver is easily possible.
