Abstract
A head-up display system including a polarizing optical engine and a first rotatable diffuser is provided. The polarizing optical engine is configured to provide a polarized image beam. The first rotatable diffuser is disposed on a path of the polarized image beam and configured to rotate when the polarized image beam passes through the first rotatable diffuser. The first rotatable diffuser is made of isotropic material, and the polarized image beam from the first rotatable diffuser obliquely strikes a windshield and is then reflected by the windshield to an eye of a user.
