摘要： Head-up display (HUD) glass and a head-up display system are provided in the disclosure. The Head-up display glass includes an outer surface and an inner surface opposite to the outer surface. A transparent nanofilm used for reflecting P-polarized light is disposed on the inner surface, and the transparent nanofilm includes a first high-refractive-index-layer, a second high-refractive-index-layer, a first low-refractive-index-layer, a third high-refractive-index-layer, and a second low-refractive-index-layer which are sequentially stacked on the inner surface. A refractive index of each of the first high-refractive-index-layer, the second high-refractive-index-layer, and the third high-refractive-index-layer is greater than 1.8, and a refractive index of each of the first low-refractive-index-layer and the second low-refractive-index-layer is less than or equal to 1.8. The technical solutions of the disclosure can solve the problem that a HUD image presented by the traditional head-up display glass is not clear, so that a driver or passenger can see a clearer HUD image, improving visual comfort and user experience.
