High temperatures, vibrations, and tight tolerances: Display bonding placed the highest demands on materials and workmanship. The first choice of material failed due to vibration damping—the second due to price. INNO TAPE accompanied the development from the outset, optimizing the material, liner, and

grip tabs and developed a tailor-made application concept. The result: stable processes, reduced variety, and lower costs. Find out in our case study how material testing and presentation ensure series production capability.

Today's modern vehicle displays must do much more than just look good—they are both central control elements and information surfaces. As the interface between driver and vehicle, they control navigation, assistance systems, and infotainment, and must therefore function precisely and reliably at all times.

Specifically, this means: 

High temperatures, vibrations, dust, moisture, or light reflections—all these factors have a direct impact on the bonding technology used and make the connection between the display and the component a complex challenge.

Only when all components work together perfectly can a vehicle display function reliably, safely, and visually convincingly over the long term—even under the most demanding conditions.

Challenges in the project

• different substrates and tolerances
• precise adherence to the gap dimension
• tightness against dust, dirt, liquids, and creams
• vibration and impact resistance
• self-extinguishing, non-dripping materials
• temperature resistance from –40 to +80 °C

Objective

The goal was to develop a display adhesive that would meet these diverse requirements—technically robust, visually precise, and reliable in assembly.

Based on the drawing provided by the customer, an application concept was developed in collaboration with the development team. The focus was not only on the adhesive tape itself, but also on the entire assembly process.

Several test runs were carried out with materials  from different manufacturers. The  material initially used did not fully meet the  requirements for vibration damping. Therefore, a switch was made to another material with an even better price-performance ratio.

Originally, four grip tabs were planned, but by optimizing the assembly process, two were ultimately sufficient. This not only reduced costs but also simplified handling. An additional liner reinforcement with recesses also ensures precise positioning in the assembly fixture.
