AUTOMOTIVE DISPLAY ON WINDSHIELD Russian patent published in 2020 - IPC G02B27/01 

FIELD: image forming devices.

SUBSTANCE: invention relates to electronic engineering, particularly, to displays on car windshield. Display on vehicle windshield includes arranged in series along optical axis LED backlight consisting of at least one light-emitting diode with peak wavelength of blue radiation 475–490 nm, system of optical films, including diffusively scattering and raster prismatic films, intended to ensure uniformity of illumination emission, and composite (zoned) composite photoluminescent film containing in a transparent base photoluminescent substances for conversion of blue light-emitting diode radiation to green-blue radiation for the augmented reality display area and red radiation for the warning information display area, a monochrome liquid crystal display, a Fresnel lens projecting, with magnification, an image formed on the liquid crystal display into the space in front of the vehicle windshield.

EFFECT: technical result consists in reduction of harmful effect of display radiation on body of driver and passengers of car, simplified design, increased reliability and efficiency of display on car windshield.
