There are a number of industrial displays which use 23-segment columns to show semi-rounded alphanumeric characters and simple icons. An example photo:
I cannot find anything about this system, like its name or a concrete product.

3\$\begingroup\$ It may not have a name : it looks like a custom product with segments designed to took reasonably good on European languages. I've certainly never seen small LED based devices like you can for n-character 7 segment displays, for example. You can have custom LCDs and possibly electroluminescent (EL) made to your own drawings. Maybe that's what happened here. (The design may be copyrighted or patented; search for patents from the manufacturer) \$\endgroup\$– user16324Commented Aug 15, 2020 at 11:54

1\$\begingroup\$ What famous painting is this from? Or maybe this one? Do you see my point? \$\endgroup\$– Andy akaCommented Aug 15, 2020 at 12:06

\$\begingroup\$ @Brian Yes it might be a proprietary solution. It would explain why I have found nothing about it. \$\endgroup\$– scriptfooCommented Aug 15, 2020 at 12:17

1\$\begingroup\$ @Andy Not quite. The image shows a complete column to the right. Do you mean that it is not any common standard like the sixteen-segment display? \$\endgroup\$– scriptfooCommented Aug 15, 2020 at 12:23

1\$\begingroup\$ The first one is "Girl with a Pearl Earring" by Vermeer. The second is "The Birth of Venus" by Botticelli. Both recognizable to a non-expert (me) even in the extremely cropped versions. In the same way the cropped images in the question are recognizable to anyone who has seen them. \$\endgroup\$– JRECommented Aug 24, 2020 at 15:25

The example in your question shows a text in German, and is either from a bus or streetcar.
This German company makes LCD displays for buses. The LCD panels appear to be custom made - either ADITECH orders them made that way, or makes them in house.
In any case, they are LCD panels with custom drivers for the unusual "pixel" shapes.
The shapes used in the LCD pixels are based on shapes used in earlier "flip dot" displays.
I have been on buses that used the mechanical flip dots, but that was long ago (more than 20 years.)
If you want that kind of panel, you'll have either order them from an LCD panel manufacturer, or buy a used bus display (if you just want it for a hobby kind of thing.)
