Abstract

A retroreflective one way vision film applied to the rear window of a vehicle. This film provides high visibility from the outside looking at the vehicle due to the retroreflectivity and also allows the driver to see outside the rear window due to the one way vision perforations. The idea is to combine a perforated retroreflective film with black adhesive or black film with adhesive and apply this to the outside of a vehicle. Currently all school buses in Turkey are required to have a reflective material applied on the back window. School buses use reflective film to cover all rear windows which prevent the driver from seeing out of the back of the vehicle. The film meets the reflective requirement and also allows the drive to see out of the rear window.

Perforated reflective film for vehicle window application. Abstract:

A retroreflective one way vision film applied to the rear window of a vehicle. This film provides high visibility from the outside looking at the vehicle due to the retroreflectivity and also allows the driver to see outside the rear window due to the one way vision perforations. The idea is to combine a perforated retroreflective film with black adhesive or black film with adhesive and apply this to the outside of a vehicle. Currently all school buses in Turkey are required to have a reflective material applied on the back window. School buses use reflective film to cover all rear windows which prevent the driver from seeing out of the back of the vehicle. The film meet the reflective requirement and also allow the drive to see out of the rear window.

Detail:

It is mandatory to use reflective film on the back of school buses in Turkey. Unfortunately the current reflective film is opaque so it blocks the rear window view of the driver. The solution is to combine a reflective film with black adhesive or black primer or black film layer and an adhesive with all layers perforated.

How perforated film (one way vison or see-through graphics) works.

When looking at a vehicle with a perforated graphic (from the outside), the human eye will see the light that reflects from graphics printed on the film. The areas of the film with perforations appear darker than the graphics and the eye does not perceive...
