Abstract: Provided are a display device and a preparation method thereof. The display device includes a display panel and a first antireflection structure and a second antireflection structure successively stacked on a side of a display functional layer facing away from a driving substrate, where the display panel includes the driving substrate and the display functional layer. The first antireflection structure includes a first graded-index layer, a conductive layer and a second graded-index layer which are successively stacked; the first graded-index layer includes at least two first sublayers, and the second graded-index layer includes at least two second sublayers. The second antireflection structure includes a third graded-index layer, a first dielectric layer and a fourth graded-index graded layer which are successively stacked; the third graded-index layer includes at least one third sublayer, and the fourth graded-index layer includes at least two fourth sublayers.

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.
