A couple of weeks ago, we were hoping in this blog that spring would soon arrive and promised that the next display blog posts would be about other kind of extremes than the cold.

We take it back. The spring has not come to Finland yet (it is actually still really cold here – challenging climate, you know) so we decided to do one more post about our rugged displays in demanding conditions.
Displays for extreme cold
When we meet people and discuss what “Displays for extreme conditions” really means, one typical topic is how our rugged Lumineq TFEL displays and the transparent and in-glass laminated TASEL displays function in cold environments.
Instant on, no motion blur in -60 degrees Celsius. That’s how. It is unique performance for a display without heating or any extra hardening, but we appreciate the fact that it is difficult to imagine what this means in practice without actually seeing. Last month we showed the cold performance of our displays in Alaska and the results were impressive, but most people obviously don’t have the possibility to just go outside in -40 degrees and start testing displays.
A comparison test: Lumineq TFEL vs. LCD display in the cold chamber
So how well does a Lumineq display really run in extreme cold? Is it really true that the Lumineq displays don’t have any motion blur in -40 degrees? How big is the difference with an LCD display? What does it look like when the LCD display fails in -40?
To show you this, we made a quick video in one of our cold chambers we use for testing our displays at our factory in Espoo, Finland. In the video, you can see one of our standard TFEL displays in the cold chamber side by side with an industrial grade LCD display. The difference is crystal-clear: The rugged Lumineq TFEL display maintains perfect readability in -40 degrees while the LCD display – well, does not.
But don’t just take our word for it. See for yourself!
