US 2014/0232707 A1 · DEVICE FOR GENERATING A DISPLAY IMAGE ON A COMPOSITE GLASS PANE

Abstract

A device for generating a display image on a composite glass pane is described. The device has: a composite glass pane with a first pane and a second pane, which are connected to each other via an intermediate layer that contains at least one luminescent pigment; a laser projector, which contains at least one laser and an optical system for deflecting a radiation of the laser, the radiation being directed within a region of the composite glass pane; a photodetector, which detects luminescent radiation of the luminescent pigment; and a control unit, which electronically connects the photodetector and the laser projector.

A device for generating a display image on a composite glass pane, comprising:

a composite glass pane with a first pane and a second pane, which are connected to each other via an intermediate layer containing at least one luminescent pigment;
a laser projector, which contains at least one laser and an optical system for deflecting a radiation of the at least one laser, wherein the radiation is directed within a region of the composite glass pane;
a photodetector, which detects luminescent radiation of the at least one luminescent pigment;
and
a control unit, which electronically connects the photodetector and the laser projector,
wherein the control unit interrupts an emission of radiation from the laser projector when no luminescent radiation is detected by the photodetector.
