Title:
GLASS LAMINATE WITH PRINTED OBSCURATION HAVING SUPERIOR STRENGTH AND OPTICAL QUALITY
Document Type and Number:
WIPO Patent Application WO/2019/064275
Kind Code:
A3
Abstract:
The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of the windshield is less than 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 obscure the camera hardware. The abrupt thermal gradients during bending, caused by the heat absorbing black frit, result a high level of distortion in the camera field of view. The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by creating an obscuration, after heating and bending of the glass, by printing the obscuration on one or more of the surfaces of the bent glass in or near the camera field of view (camera obscuration) or / and in the edges of the windshield (black band) rather than printing and firing an enamel frit on the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.
