Laminate with printed visual impairment showing better strength and optical quality

摘要

The use of camera-based systems is growing rapidly in modern vehicles. At the same time, the windshields in which many of the cameras are mounted are becoming larger and more complex in their shape. As the industry moves on vehicles with full automatic capability, both the number of cameras required and the resolution of the cameras increase. However, the optical quality of the windshield is not optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass prior to heating and bending to hide or hide the camera hardware. The abrupt thermal gradients during bending caused by the heat absorbing black frit result in a high level of distortion in the camera field of view. It is an object of this invention to provide a laminated vehicle glazing having a visual obstruction area created by creating a visual obstruction after heating and bending of the glass, by printing the visual obstruction on one or more of the surfaces of the curved glass in or close to the camera field of view (camera visual obstruction) or / and in the edges of the windshield (black stripe) instead of printing and burning an enamel frit on the glass a laminate having a higher optical quality, a higher strength and a lower probability of breakage compared to a laminate with a visual obstruction made of black enamel frit.
