Abstract
An anti-glare head-up display system for vehicles includes a projection imaging unit and a curved mirror. The projection imaging unit is in an upper region of a cabin of the vehicle. The curved mirror is on a top surface of an instrument panel of the vehicle. The curved mirror includes a doped glass, a high-reflection coating and a dark coating. The doped glass and the dark coating absorb visible light. The high-reflection coating is on a surface of the doped glass facing the projection imaging unit and has a high-reflection effect at wavelengths corresponding to light sources used by the projection imaging unit. The dark coating is on another surface of the doped glass opposite with the projection imaging unit. Light rays emitted by the projection imaging unit are projected onto the curved mirror, and light rays reflected from the curved mirror are projected onto the windshield to form a virtual image in front of the windshield. Light rays of ambient light projected onto the curved mirror which do not belong to the wavelengths corresponding to the light sources pass through the high-reflection coating and are absorbed by the doped glass and the dark coating.
