I need to have a project that will require as low of a power consumption as possible. I want to add am LCD but it will really only be looked at during setup and periodic monitoring. So I don't really need a a back light.
I could probably drive the LED with PWM and turn it off when not needed but why go through all of the trouble.
I was looking at this LCD. It has a TN, STN display. Do I really need to hookup that backlight to be able to view the LCD or will it work fine without the light?
Wht is it listed at both TN and STN?
Is there a reference that I can go to that talks about the pros and cons of the various types?
