I'm working on an application using a msp430f6458 and I'd like to add a LCD.
Power consumption is very important to me, and I need to display 4 characters (4*8-segments).
Those characters need to be displayed 24/7, and will almost never change (twice a day at most).
Obviously, I won't include a backlight.
I've searched for passive segmented LCDs online, but I couldn't find any with power consumption information (other than "low power"), and whether I need to refresh them (i.e. wake the microcontroller) often.
I would appreciate it if you could point me towards some suitable LCDs, and maybe help me understand how the LCD refresh process works, how much power it uses, and whether I need to wake the CPU.
Thanks a lot in advance,
