S-LEC™ Wedge Shaped Film

Interlayer films used for windshields and other automobile glass are required to have various additional functions beyond the basic shatterproof function.

Meanwhile, as on-board electronic devices and their processing capabilities evolve, the functions and roles of on-board displays are also evolving. One such display is the Head-Up Display (HUD). By putting the display function on windshields and other areas, the necessary information such as vehicle speed, directions, and alerts can be obtained without having to significantly change one’s driving posture and line of sight, which is expected to enhance driving safety.
Standard windshields with interlayer films typically pose the problem of double images projected from the HUD due to light refraction, resulting in reduced visibility.
In addition, the more advanced augmented-reality Head-Up Display (AR HUD) needs to precisely control the refraction of light over the entire projected area in order to display information on top of the actual sight of the road.

Windshields with S-LEC™ Wedge Shaped Film can control light refraction with high precision and project images clearly. The film is also compatible with the wide-angle view of an AR HUD and can project images clearly over the entire display area.
The film can be used in a wide variety of HUDs, such as dual-screen display HUDs and an AR HUD, as well as in various types of vehicle bodies with windshields at different angles.
It can be combined with different solutions such as sound and heat insulation.
