And the problem with that is..?
I'm sure Dave will (if only out of necessity/MOQ) have plenty of displays available
The cost of buying parts (whether from Dave or making your own batch) has no bearing on the open-sourceness or otherwise.

I agree 'cost' has no baring, that is not my 'issue'.  My 'issue' (a term grossly exaggerated, as I will not personally be affected, but do feel is worth mentioning), is that the part relies on purchasing a part only available via the designer of the 'open source' project.  Obviously other parts are also proprietary, but they are not affiliated with he designer. i.e you can only follow the free design by Dave, by purchasing the display from Dave.  It does seem a bit borderline to me.

LCD character displays used to be expensive for lithography, glass - high NRE, high min. order quantities and long lead times. For a basic display like this, I don't see it worth it.
You'd always have a box of 10,000 displays lying around.

Had a product with similar custom LCD display from GPEG in UK and very low cost, no big MOQ, and their own graphic design software. Hit'em up and see. It was refreshing to not have to spend big bucks.


OP's LCD display has no innovation, it's just some numbers.
A power supply from 40 years ago has the same numbers, just on an analog panel meter. Yawn.

This small OLED meter I buy for $7 and put on my bench power supplies. Popular meter in china.
It has extra measurements I find useful, such as Ahr, run time, temperature from a STM32.

I do not know the project here but wonder if it's to be low cost or what the goal is.

Example of a terrible UI.

What's terrible about it?
One button, press and hold to reset integrators. Press again to do calibration.
