More Information
Summary:A windshield of a vehicle includes a reflective polarizer. The windshield is configured to receive and reflect an image light emitted by a display toward a passenger of the vehicle, such that for a substantially normally incident light, the windshield has first and second reflection spectra versus wavelength for the incident light polarized along respective first and second directions. The first reflection spectrum includes a plurality of reflection bands. Each of the reflection bands has a maximum reflectance R1max between 20% and 80%. Between each pair of adjacent reflection bands in the plurality of reflection bands, the first reflection spectrum has a minimum reflectance R1min between 5% and 25%. In the visible wavelength range, the second reflection spectrum has a maximum reflectance R2max and a minimum reflectance R2min, such that R2max and R2min are within 15% of each other.
