You send the ILI9481 to sleep with the "Sleep In" command (0x10)
And you wake it up with a "Sleep Out" command (0x11)

I would guess that Einstein could have managed to look that up in the datasheet.

Incidentally, these are the same commands for all modern TFT controllers.

It is fairly pointless sending a controller to sleep unless you can control the backlight LEDs.
That is where most of the power goes.
