What are the approx dimensions? 

mariush:
Just for fun, you could just order thousands of those 0603 leds and make your own seven segment digits at the size you want.

Then just use some of that brown/black foil (display film) that improves contrast and spreads the led light more uniformly and maybe laser cut the segments from a transparent plastic foil you can stick to this display film.

Probably costs more in leds and pick and place and all that, but no MOQ, no tooling costs, you can iterate through several layouts faster etc etc 

ebclr:
LCD main reason is cost, if cost is not an issue a TFT will fit much better than a lot of Leds, one LCD like that will cost less than 1USD, in 1K units, plus 300Usd for tooling

I quite agree, for over the years I've seen many a piece of otherwise excellent kit made virtually unusable by a poorly thought out display, assuming there was any thought put into the design beyond cramming on as much display information as possible. Sometimes less is more, as Whale's improvement over the  original, while relatively minor in of itself, leads to a significantly more readable display,at least IMO. 


Unfortunately, over the years, I found that for all their other good qualities, engineers were often the last people you wanted in charge of designing displays and UIs. For unless they had some training in display/UI design, the tendency was to cram every piece of information they could onto the display. Something I have been guilty of myself in my early years in engineering before I was lucky enough to work for some multi-disciplinary teams that included members who maybe had little or limited engineering experience, initially anyway, but did understand what worked in displays and UIs with many often coming from a graphic arts or design background.

KNSSoftware:
Is this not suppose to be an open source project though?  As much as I would love to follow the experience of getting a custom display designed and produced, does it not go against the point of this particular project, if we can't build our own one without buying one of your custom displays?
