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.

Abstract: A display device and an imaging system are provided. The display device includes a double-sided display module, a reflective component, and a curved mirror. The double-sided display module includes first and second light-exiting surfaces. In a first direction, light emitted from the first light-exiting surface is projected to a first position on the curved mirror. The reflective component at least reflects light emitted from the second light-exiting surface to a second position on the curved mirror. In a second direction, the curved mirror reflects the light emitted from the first light-exiting surface and the light emitted from the second light-exiting surface and reflected by the reflective component, to form a first virtual image and a second virtual image. Along the first direction, the first virtual image is spaced apart from the second virtual image, and the first direction intersects the second direction.
