I managed to get my OMD to work like this: - Back LCD off, unless I hit MENU (toggles menu on/off) or INFO (cycles round SCP, then level gauge, then off) - EVF auto-on via eye proximity This makes a HUGE difference to battery life. This is what you do: 1) Menu -> Gears -> Menu K (Utility) -> Touch screen settings -> OFF 2) Menu -> Gears -> Menu D (Disp) -> Control Settings -> PASM -> Live control Off + Live SCP On 3) Menu -> Gears -> Menu J (Built-in EVF) -> EVF Auto Switch -> On Now, press the button on the right of the 'prism' and you can switch between EVF and LCD. When EVF is selected, it will turn off automatically when you remove your eye - so both displays off. EDIT - > I've found that I can turn touch-screen back on and it continues to work in this way, but not sure if this is a necessary step or not so I've left it in the instructions. Hope this is helpful.
