  • Patent number: 11360254
    Abstract: An optical film, a fabrication method thereof, a windshield, and a driving apparatus, which pertains to the field of in-vehicle devices. The optical film includes a birefringent layer. The birefringent layer splits light transmitted through the optical film into two light beams, and exit directions of the two light beams are different from each other. A head up display is disposed above an instrument panel, and the optical film is disposed on a windshield. Light incident into an automobile through the windshield is split into two light beams. By adjusting relative positions of the head up display and the optical film, it is possible to enable only one of the light beams to be incident into the head up display. Since the total amount of light entering the head up display is reduced, the temperature rise inside the head up display can be mitigated.
