The customer wanted to have a bigger display in their current portable device. Interface, pinning & mechanics had to be the same.

The customer asked for a sunlight and night readable display with better optical performance than the running one. They needed low power consumption and ruggedness for his handheld, battery powered underwater device.

The customer was in enormous time pressure and had a big requirement catalogue.

It takes very long to get all metric certifications in each country, so that a very long product lifecycle was mandatory and a defined last time buy procedure.
The customer was interested in low integration effort, same electrics & mechanics for different devices and a budgetary price.
