Eyewear display device with improved beam splitter units

Abstract

The disclosure relates to an eyewear display device (1) for displaying a virtual image in a field of view of a user, comprising a screen unit (1) with a line-shaped display (2) for emitting light (3) in a first direction; at least two partially transparent beam splitter units (4) arranged at respective vertical positions (y1-y6), which are designed to be operated as scanner units, for deflecting the light (3) emitted in the first direction from the screen unit (1) into a second directional range corresponding to the field of view of the user, where respective reflection surfaces (4a) of the beam splitter units (4) are configured to oscillate about an axis of rotation (R) running transversely to the first direction; wherein a vertical size (V) of the reflection surfaces (4a) of the different beam splitter units (4), which is measured in a direction perpendicular to the axis of rotation (R), decreases along the first direction so as to provide an eyewear display device (1) for displaying a virtual image in a field of view of a user with reduced optical complexity while maintaining a form factor as close to the form factor of ordinary glasses as possible.
