The Head-up Display (HUD) eliminates the driver’s need to shift his/her line of vision by showing the necessary information on the windshield, and significantly enhances driving safety. SEKISUI’s high performance interlayer film for HUD has succeeded in adding the sound insulation and solar control functions to the HUD display glass. The film is a leading technology of the era and the newest solution supporting a safer and more comfortable automobile experience.

A world’s first created by combining three types of technology

SEKISUI has succeeded in the development of a wedge-shaped interlayer film for HUD that controls the appearance of double images, while also providing both sound insulation and solar-heat reducing functions for the first time in the world. Through the combination of multi-layer extrusion and nano-dispersal technologies, along with the newly-developed wedge angle control technology, SEKISUI has created a five-layer interlayer film for HUD with sound insulation and solar control functions achieved in a single sheet.

[Visibility] Clearly displays information necessary for driver

Standard windshields cause projector images to appear as double images due to the inflection of light. HUD windshields control for the inflection of light by adopting a wedge-shaped cross-section and enable images to be projected clearly. The film for HUD thus enhances visibility and contributes to a more comfortable and safer driving experience.

[Sound Insulation and Solar Control Performance] Shields noise and heat unnecessary to driver

As clearly demonstrated by the graphs, SEKISUI has made it possible to have a film for HUD that combines a high level of sound insulation and solar-heat reducing performance.
