Are you currently developing any displays with USB connections? And what about this new oled technology, are you planning to create backplates for them?

OK
But how's with the lifetime? Can it be on 24/7?

What is the lifetime of a VFD compared to a LCD?
As you can see here , it looks as if the BLK202A isn't made for the VK202-25, but does fit nevertheless. There is some space right next to the last characters of the VFD. Or is this just a visual illusion?
If not, is this fixed in the MK2021?

Thanx ...
