does somebody know if it is possible to turn off the Neo's display?
Currently only the backlight is disabled and the display still stays
on (what's totally useless and a waste of energy).
Does anybody have any idea how much energy just updating/driving the
display without backlight consumes?
I would guess it is relatively little - the discussions on the wiki:
http://wiki.openmoko.org/wiki/Neo1973_GTA01_Power_Management
all seem to be about the power usage of the backlight. So I would think
that efforts to reduce power consumption might be better used elsewhere.
IMHO, the critical power consumption parameter is how much the GSM
subsystem uses while idle, but connected to the network. This is
apparently quite high on the GTA01 (50 mW?) making long standby times
impossible. Hopefully the GTA02 will use less (<10 mW) (see the
neo1973-hardware archives for a discussion this month (December 2007).
Anything that uses substantially less than this will have a marginal
impact on standby time.
