"textContent": "A sunshade assembly of a vehicle includes a sunshade including a frame, and a polymer-dispersed liquid crystal (PDLC) film secured in a frame. A drive apparatus is operably connected to the sunshade to urge the sunshade between a retracted position between a roof panel and a headliner of the vehicle and an extended position protruding from the headliner. A method of operating a sunshade of a vehicle includes determining a level of sunlight glare on an operator of the vehicle and comparing the level of sunlight glare to a predetermined threshold. A sunshade, including a PDLC film, is moved between a retracted position between a headliner and a roof panel of the vehicle and an extended position partially across a windshield of the vehicle. The PDLC film is selectably energized to change the opacity of the PDLC film in response to the determined level of sunlight glare.",
