There is an error in your link, so I'm posting the images.

I would vote for the 5 LED chip, similar to the HP displays, and more appealing in my opinion than the 9 LED model.
A 14 segment LED in the same style would be very original.

If I had just seen the pictures without any text to accompany them, I would have been convinced that what we are looking at is an old HP buble LED module and an east German LEDs mate by RFT.
Now I am confused, did the Chinese make 1:1 copies of those 40 year old designs?!?

Edit: Guess I was wrong: the second picture is of a Commodore Minuteman display : http://www.vintagecalculators.com/html/c...plays.html

Edit 2: I read the original post again and think that these are only examples, not the real units. So we'll have to wait and see.
