Saflex® VIEW ST

HUD Interlayer Resolves Driver Height Challenges

HUD (heads up display) systems are an effective method to help combat driver distraction. Today’s systems enhance the overall driving experience by allowing drivers to keep their eyes on the road and still view critical vehicle data. The Saflex® VIEW ST interlayer offers an advanced solution for the complex curved or steep angled windshields commonly used in trucks and SUVs.

One challenge with automotive HUD systems is projecting a well-focused image on the windshield. When the image is reflected through multiple layers of glass at an angle, visual distortion — commonly known as ghosting — can occur.

And while a larger number of automotive OEM platforms employ HUD systems, there are some limitations. Not every driver is the same height.

Conventional, single-angle HUD PVB solves ghosting for drivers at a nominal height, but may not meet levels needed for short or tall drivers. The problem becomes even more problematic in vehicles with a complex windshield curvature or steeper rake angle.
 

A Dynamic Wedge Interlayer for Complex Windshields

Eastman’s Saflex  VIEW ST is a next-generation interlayer that helps eliminate HUD ghosting in trucks and SUVs. VIEW ST’s wedge angle can be calculated and tailored to the HUD box. This increases the usable HUD zone for short and tall drivers, improving image clarity by minimizing ghosting.
 

For successful growth, HUD systems of today and tomorrow require innovation like the VIEW ST dynamic wedge interlayer.

Saflex® HUD / QHUD

Saflex® HUD

Forward-Looking Innovation

Driver control is looking ahead in the automotive industry. Head-Up Display (HUD) technology, once reserved for fighter jets and luxury cars, is now available due to advances in polyvinyl butyral (PVB) interlayers.

HUD technology enhances the overall driving experience by allowing drivers to keep their eyes on the road and still be able to view critical vehicle data.
Traditional PVB interlayers have a flat uniform surface. Using a proprietary process, Saflex® HUD interlayers feature nonparallel surfaces to create a windscreen that provides better optical correction. This has resulted in the highest quality projected image in the market (see image below for illustration).


 

A Pioneer in Head-Up Display

OEMs and glass laminators trust Saflex HUD to be the best. We helped pioneer the development of HUD interlayers more than 20 years ago. Working jointly with HUD channel partners provides us with a robust understanding of how to enable best-in-class HUD optics performance and ensure the smooth launch of each HUD vehicle program.
Saflex HUD interlayer technology provides automotive engineers cost-effective, easy-to-implement HUD features. Saflex HUD products deliver this high quality while also decreasing cabin noise, reducing vehicle weight, improving gas mileage, and lowering CO2 emissions.
Saflex provides a variety of HUD products to suit any make and model’s unique image requirements:

  • Saflex HUD
  • Saflex QHUD (acoustic HUD)
  • Saflex VIEW ST — made specifically for complex windscreens to fix short/tall image

Saflex® QHUD - Same Benefits. Even Better Acoustics.

Saflex® QHUD is an enhanced acoustic PVB interlayer that provides all the benefits of Head-Up Display technology with even better acoustics. The noise level within the cabin is reduced by up to 3 dB versus a standard windscreen and up to 5 dB compared to tempered side windows. The selection of Saflex QHUD provides drivers with less sound distraction so they can keep a sharper focus on the road ahead.

Applications:

Windscreen

Product Benefits:

  • Improves acoustic comfort: Reduces exterior noise by up to 3 dB
  • Reduces Weight: Implements thinner, lighter glass without increasing noise
  • Increases fuel efficiency: Lighter weight glass lowers fuel consumption
  • Reduces CO2 emissions: Improved fuel efficiency helps meet U.S. EPA targets
  • UV protection: Blocks more than 96 percent of harmful UV radiation
