Display device e.g. head-up display, for motor vehicle, has piezo-motor comprising piezoelectric unit and surface that is connected directly or over grating flange with unit, where position or geometry of image forming device is adjusted

摘要

The device has a piezo-motor that includes a piezoelectric unit (1a), and a surface (3a) that is connected directly or over a grating flange (2a) with the piezoelectric unit. A position or geometry of an image forming device (4), which produces real and virtual images within a motor vehicle, is adjusted. The virtual image is projected against a combiner over an optical path, such that the virtual image is perceived behind the combiner.
