What display technology and make?
(OP)
Needs: 4 rows 16 or 20 characters. No graphics. Light-emitting or reflective with background light. Light on/off/intensity selectable. Colour OK but not necessary. Mature technology.
Constraints: Shall work from -20C to around +50C. Lowest possible (<10 mA) power consumption. Life better than 50 000 h. Cost lower than USD 30 in 100+ quantity.
I have quite a few candidates, but may have missed a few. Suggestions?

Half full - Half empty? I don't mind. It's what in it that counts.

RE: What display technology and make?
You probably know this already. Useful search terms for those characters counts are "1604" or "2004", combined with terms like LCD and/or Arduino. Problem is, the market is ~99% the same old LCD with the usual LED backlighting. I did find an OLED exception.
Swapping out the backlight technology in an existing module might be a bit intricate.
Good luck.
RE: What display technology and make?
I've learned that these development boards (I'm using Arduino) can be programmed to turn off the LCD completely by powering it from the digital output pins, rather than constantly on the 5VDC power supply, which is always on. When a button is pushed, the digital pin used is set to HIGH, permitting power to the LCD. I haven't tried this yet, but will once I have the hardware all sorted out.
The LCD I bought (Ladyada) is an energy hog so I won't recommend it for your job.
No I'm not making anything slick like your silk-screened touch panels, which look very professional, BTW.
