lcd display, led display,.... ??
for a led display things are fairly obvious
for lcd display, much relies on the polarisation frequency of the display
since it's the switching consuming the energy
so for a definite answer on lcd..... sorry
I just built a PIC circuit that turns off the LCD when it's not needed.
With the LCD on, the current was 2mA. With it off, the current was 0.75mA.
Now, invent a display that only turns on when you are looking at it. Or
better yet, only turns on when you are paying attention to it.
