Cover Glass
The cover glass is made from scratch-resistant, coated polycarbonate (PC) and forms the top cover of the HUD. The cover glass protects the interior of the HUD against dust and objects accidentally placed on it.
The glass combined with the HUD trim are curved so that any incident light is not reflected back to the driver.
It also guarantees unobstructed projection of the display information onto the windshield without interference from stray light effects, for instance.
