Image display generator for a head-up display

摘要

An image display generator for use in a head-up display includes an array of light emitting devices such as LEDs or VCSELs formed on a semiconductor layer deposited on one surface of a glass like, e.g. Sapphire, sheet in which a plurality of lenses are formed on the opposite surface with each lens aligned with a respective one of the LEDs or VCSELs. A layer of transparent insulating material is disposed over the semiconductor layer and is coated with a reflecting material. Light emitted by the LEDs is directly incident onto respective over the lenses and is indirectly reflected onto the lenses by the reflecting material.
