The present invention relates to generate the device of display image on composite glass, it comprises: have the composite glass (1) of the first plate (3) and the second plate (4) interconnected via the intermediate layer (2) containing at least one luminous pigment (8)；Laser-projector (5), it contains at least one laser instrument (9) and the optical system (10) being used for making the radiation (11) of laser instrument (9) to turn to, and wherein radiation (11) guides composite glass (1) in a region (7) of composite glass (1)；Photodetector (6), the luminous radiation (12) of its detection luminous pigment (8), and control unit (13), its electronics connects photodetector (6) and laser-projector (5).Can detect the barrier between laser-projector (5) and composite glass (1), because in this case, photodetector (6) is not detected by luminous radiation (12).Therefore the harm that people is caused by the radiation (11) of laser instrument (9) can advantageously be reduced. |
