Holographic head-up display apparatus

摘要

In a head-up display such that display images of instruments within a dashboard can be projected upon part of a windshield of an automotive vehicle, the holographic head-up display apparatus comprises a light emitting display unit; a transmissive hologram plate; and a reflective hologram plate. Since visible display images can be seen by the driver after having been passed through the transmissive hologram plate and reflected from the reflective hologram plate, blur of the display image due to chromatic aberration can be cancelled out, thus providing clear head-up instrument images.
