Hoffmann + Krippner offers display solutions suitable for applications in bright environments. A special bonding technique, known as optical bonding, ensures a clear view even in low light conditions.
An air gap is commonly located between a filter wheel or a touch screen and the display behind. This causes the image to lose its brilliance and distracting reflections to develop. The bonding fills the air gap using a high-quality, transparent adhesive, eliminating it completely. The light refraction caused by the gap can be reduced significantly.
The liquid adhesive also prevents moisture from gathering in between the display and touch screen and prevents possible condensation. Screen clouding after longer operating times is therefore no longer an issue.
In addition to these benefits, the entire optical system is much more robust to temperature fluctuations and mechanical stress due to the air-filled gap. Bonded screens, otherwise more sensitive, can now also be used in industrial and outdoor applications.
