Abstract
Provided are a head up display system and a vehicle. The head up display system includes a control module, an image source module and an imaging module. The image source module includes a display component and a dimming component, and the dimming component includes a polarization state adjusting unit, a metal wire grid and a reflector. The display component is electrically connected to the control module. The polarization state adjusting unit is configured to modulate the imaging light into polarized light in a first polarization direction and polarized light in a second polarization direction. The imaging module is configured to transmit the polarized light in the first polarization direction or the polarized light in the second polarization direction to a windshield, and the windshield reflects the first polarization direction or the polarized light in the second polarization direction into a human eye for imaging.
