MULTILAYER GLASS FOR PROJECTION DISPLAY ON GLASS Russian patent published in 2020 - IPC B32B17/10 B32B3/26 

Abstract RU 2715871 C1

FIELD: manufacturing technology; image forming apparatus.

SUBSTANCE: invention relates to a multilayer glass for a projection display on glass (HUD-display) for use in vehicles, particularly a passenger car. Multilayer glass contains at least one first glass sheet and one second glass sheet, which are connected to each other with a composite layer, as well as a transparent electroconductive coating. Composite layer comprises first thermoplastic film, polyester film and second thermoplastic film with ratio of thickness of second thermoplastic film and first thermoplastic film from 1.5:1 to 20:1. First thermoplastic film and the polyester film have a common edge which is at least partially spaced from the edge of the second thermoplastic film, and the first thermoplastic film has thickness of 40 mcm to 110 mcm.

EFFECT: invention provides creation of multilayer glass for HUD-display, which minimizes disturbing effects caused by roughness of surface of layered structure.
