I am not an engineer so forgive me if I am saying something stupid, but
is not the goal to switch off the backlight if and only if there is no
difference between the switched on and switched off state? I mean that
this implies that you have to measure the mV at a light level when you
cannot see the difference (what can be a much fainter light than the sun).
