About DEIF

DEIF A/S is a Danish company that produces controllers for use on land and water and marine bridge instrumentation. For DEIF A/S, innovation is the foundation upon which all products are based. Covering just under half of the world market, the company is a market leader in marine bridge instrumentation.

Challenge

Marine bridge instrumentation has high demands to cover glass solutions, as they require maximum readability from all angles out on the water. For instruments placed outside, weather-sealing, resistance to salt water, and an ability to withstand all types of weather are crucial. That is why DEIF continuously works on improving its solutions to achieve the best performance possible. It is also here that the company has its competitive advantage, as the individual instruments can be tailored to the customer's need for scale displaying.

 

Solution

To improve the readability of the instruments, DEIF A/S has changed its solution from an injection-molded cover to a cast acrylic cover glass solution in front of an LCD-TFT display. The new design and display solution avoids color differences in the display. The company has invested in a cover glass solution for the display from PSC A/S. The solution is called Fine Hard MatTM.

The cover glass solution is based on acrylic, on which a surface treatment has been applied on both sides. The front side of the acrylic cover glass has a hard mat coating, while the rear side has a hard coating.

Martin Gudbjerg, the Senior Hardware Designer at DEIF A/S, comments on the new solution:

There is better optical performance in the PMMA with the Fine Hard MatTM. Less haze and better transmission.”

By applying this solution from PSC, the display achieves a mat surface with anti-reflective properties, providing optimal readability from all angles due to the hard mat coating on the front side.

The Fine Hard Mat microparticles are more refined than in other mat coatings, which satisfies DEIF A/S’ requirement about the TFT display. In addition, it is dirt-repellent and thus perfect for the environment that can be found on ships. The acrylic is easier to handle because of the hard coating on both sides since it protects the cover glass from scratches during assembly.
