I posted some of these informations here ==> Mauricemeyer's Chest Display Project but because there are much to say about the chest display, I decided to do a new thread.
It's hard to tell how many sequences are (were) in total, but looking to the ESB stills from the Gallery and the screen captures (my own too) I managed to do a 7 step sequence and even to calculate a time period between most of these sequences.
Note that the images in the right side are not included in the final sequence because I didn't saw it used in any of the scenes.
The first six sequences are from one of the carbon chamber scenes while the 7th sequence is from the dining room scene:
Other scenes that prove these sequences are the following ones:
I can't tell for sure wich kind of digi characters they used, but for me is this type:
(Note: as described in the update, the correct LED character is the same for the ESB and ROTJ, and the one presented above is a good replacement, but not accurate)
This is the sequence with the time periods between them, wich I calculated watching the first scene (the carbon chamber one) frame by frame.
Note that the first and the last two sequence's time period is approximated because the scene didn't show the full sequence.
Non ESB Hero chest display facts
--------------------------------
It seems that for ROTJ they used other type of digital characters:
The first chest display is the ROTJ Hero (a repainted ESB Promo #1 chest plate) while the second image is a ROTJ Stunt (the repainted ESB Hero chest plate)
(Note: as described in the update, the LED character used on the ROTJ is the same as the ESB Hero)
Another strange thing is that for the Supertrooper/Pre-Pro #1 they used only 4 digits (these were only prototypes), and the same scheme was present on the Pre-Pro #3 too (if the images don't lie):
But for the Pre-Pro #2 (and maybe for the other two ESB Promo suits too?) it seems that they already used the 5 digit chest display:

Did some digging regarding the chest display components using this MoM image as an example:
Here is what I found as correct parts for the chest light board:
On the first image the 7 segment display is noted with 7.62mm height but the graphical representation has a 9mm height (possibly for a better view of each segment).
These images shows the perfect fit of the found parts:
And some comparison images of the ESB Hero chest light:
The only chest lights that is close to this setup is the ShackMan style board which had 5 piece of 7 segment LED display (with the dots positioned vertical) and 20 piece of 2mm wide LED bars:

Although there are some pretty good and cheap replacement parts for these boards, I would love to see a chest light made with these components.

This is my interpretation of the ESB (and non ESB) chest display and its sequence and is in no way a 100% proven statement.

This is the sequence I came up with, by no means is it perfect but I did spend some decent time going through stills and the movie in HD.
