PROJECTION SYSTEM FOR WINDSHIELD INDICATOR (WSI) WITH AREAS OF P-POLARIZED LIGHT Russian patent published in 2021 - IPC G02B27/01 

Abstract RU 2748645 C1

FIELD: windshield indicator.

SUBSTANCE: invention relates to a projection system for a windshield indicator (WSI), comprising composite glazing panel (10) containing external glazing panel (1) and internal glazing panel (2) that are connected to each other by thermoplastic intermediate layer (3), having upper edge (O) and lower edge (U), and display area (B) on the windshield, electrically conductive coating (20) on surface (II, III) of external glazing panel (1) or internal glazing panel (2) facing to intermediate layer (3) or formed inside intermediate layer (3), and projector (4), which is directed to display area (B) on the windshield. Light of projector light (4) has at least one p-polarized area, and conductive coating (20) has only one local maximum of reflection of p-polarized light in the spectral range from 400 to 650 nm, which is in the range from 510 to 550 nm.
EFFECT: invention is aimed at obtaining a projection system for a windshield indicator.
