Hey Filip,

this is not a LED display. This is a vacuum-fluorescent type (sometimes called Batron) Need a heating voltage 1,5V and anode voltage about 50V DC. The driver chip designed direct for this arrangemet, but not impossible driving with discretes. You need couple of transistors, and some reverse engineering to discover the pinout.

Without a schematic it will probably be impossible to assist you and I assume that is why you have not got any responses.

It is like showing a blind man an engine and pointing out the carburator and asking him how to make it run.
