Abstract
A head-up display has a display element, a projection system, a diffusing plate, and a mirror element. In such head-up displays, frequently irritations due to stray light occur. A head-up display that produces less irritation from incident stray light is therefore desirable. The diffusing plate has focusing elements on its side facing the projection system and a light-blocking mask on its side facing away from the projection system.
Claims18
A head-up display comprising:
- a display element;
- a projection system;
- a mirror element;
- and
- a diffusing plate having focusing elements on a side facing the projection system a light-blocking mask on a side facing away from the projection system.

2 more elements
A method for producing a head-up display, having the steps of:
- producing a focusing element on a first side of a diffusing plate;
- applying a coating on the second side of the diffusing plate that lies opposite the first side;
- exposing the first side to a beam having defined geometric properties with a wavelength, an intensity and a duration suitable for producing openings in the coating;
- and
- combining the diffusing plate with a projection system that is able to produce a beam having the stated defined geometric properties and with a display element.
