Backlight
Some drivers use the fbtft backlight support to control backlight.
These drivers will have backlight power control exposed in the sysfs filesystem.
# Turn off backlight
echo "1" > /sys/class/backlight/<drivername>/bl_power
# Turn on backlight
echo "0" > /sys/class/backlight/<drivername>/bl_power
Brightness is currently not supported (need a kernel PWM driver for the Raspberry Pi).

Note: The old fbtft way of controlling backlight was using fbtftops.blank()
