Help,Can ordinary LEDs replace thin-film LEDs?

For now, remove Q1 and Q2 in the schematic and connect a low voltage source to the VD pin. 3.3-5V is about right.
Connect the anode of the LED to one of the SEGs in the schematic and the cathode to GND. Attach a limiting resistor in series to keep the current below 0.5mA.
The cathode of the LED should be connected to the BP of the HV6506, but I do not know how the BP is controlled.
You can either connect it to the BP or to GND, whichever is better.

If this were an LCD, it would need a bias circuit to operate at about 1/3 bias, but no such thing seems to exist, rather it is an odd display, like an EL, that uses high voltage.

I once saw a video of an electric curtain used for house windows and doors. I believe it was one of those things that would be translucent when turned on, and transparent when turned off.
Maybe that is it. I believe it used high voltage as well.

But you should definitely first clarify if it´s a LC- or EL-Display. If it´s LCD then current will be far too low.

FYI, in English we never say "LC-Display". ;) We say either "LCD" or "LCD display", or the full "liquid crystal display". (Any examples you may find are invariably from non-native speakers.)

In Germany we have too many pedants who teach you "A LCD display is a liquid crystal display display"... But thanks for the hint!  :-+

Heheheh. We occasionally get that in English regarding "PIN number", "HIV virus", "ATM machine", etc. :P

The one that REALLY irks me in German is "ISB-Nummer" (for ISBN, which is "International Standard Book Number"), because it violates the internal hierarchy of that compound noun. Indeed, it ignores the fact that compound nouns have internal hierarchies, and are not flat lists of constituent words!

If you diagram it, the "head" of the compound is "Number". That compounds to (Book+Number), and that in turn is compounded to "Standard Book Number" (the originally British predecessor to the ISBN), (Standard+(Book+Number)). And when that standard was adopted by ISO and extended to an international standard, it became (International+(Standard+(Book+Number))).

So when German says "ISB-Nummer", it's violating the hierarchy by pulling out an element from the innermost set, creating a new hierarchy that makes no sense: ((Internationales+(Standard+Buch))+Nummer). There is such thing as a "Standardbuch" (=Standardwerk), but that actually changes the meaning entirely, to a number specific to international definitive books...

But alas, Duden or whatever decided that ISB-Nummer is what is officially correct, so we live with it...

I drew a simple schematic, is this what you mean?
