Abstract
A glass pane of a vehicle glazing, wherein the glass pane has a print containing scattering particles that scatter light, and wherein light coupled in at the side of the glass pane is coupled out via the print by means of the scattering particles. According to the invention, the glass pane has a curvature or a critical curvature which excludes reversible deformation of the glass pane into a planar configuration, and wherein the print formed with a printing ink in a digital printing process is situated over part of the surface, or the entire surface, of the outer curvature or the inner curvature of the glass pane.
Claims16
A glass pane of a vehicle glazing,
- where the glass pane has a print containing light-scattering particles, and
- where light coupled laterally into the glass pane is outcoupled via the print by the light-scattering particles,
- wherein the glass pane has a critical curvature that rules out reversible deformation of the glass pane to a planar configuration and in that the print formed by a printing ink in a digital printing method is disposed over part of the area or the whole of the area on the outer curvature or the inner curvature of the glass pane.
A method of producing a glass pane of a vehicle glazing and having a print containing light-scattering particles, comprising:
- outcoupling light coupled laterally into the glass pane via the print by the scattering particles,
- providing a glass pane having a critical curvature that rules out reversible deformation of the glass pane to a planar configuration,
- applying the print formed by a printing ink containing the light-scattering particles over part of the area or the whole of the area on the outer curvature or the inner curvature of the glass pane, and
- applying the printing ink in a digital printing method disposed over part of the area or the whole of the area on the outer curvature or the inner curvature of the glass pane.
