Turn LCD off when printer is not in use

I have a working #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER connected to my Arduino. It stays on whenever the Arduino has power, including the backlight.

How can I disable the LCD entirely, or just the backlight, using gcodes or some other software feature? Even better: Is there some way to make it timeout and shut itself off when the printer has been idle for a certain period of time?

It doesnt do either

You would have to hack the firmware and hardware to add this feature

Try a different LCD? Mine has a light button on the far right instead of the encoder as well as a potentiometer for controlling how long the backlight stays on for (upto 30 seconds I believe). There is then a jumper in the back to keep the light on all the time or to rely on the button / potentiometer. I want to say it is a Greetech design based on the original RRD schematics, but I honestly don't know.
