Hi,
for all that are using the touchscreen display in sel constructed mobile
devices (i.e. running on battery power), it would be great to have an
option to put the screen and its backlight into standby after a certain
time.
It seems that this is not really trivial, as the touchscreen needs to be
present at boot time and can't simply be switched off and on after
booting. There are lots of threads on this, e.g.
https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=120968&start=150
The power saving mode integrated into PCP/jivelite only works with the
official display.
I found the pinout here:
https://diyhacking.com/raspberry-pi-touchscreen-lcd-tutorial/ - its for
the 3.2 Inch display, but I suppose that its identical for the 3.5. 
Has anybody succeeded in finding a solution for a power saving mode for
the touchscreen?
Best regards
Martin
