iPad mini How to keep the lockscreen on?

[Shadyriley]

I want to have the lock screen on with the dynamic wallpaper, ipad mini running ios 7, after like 30 seconds the screen turns to black, how do I make it stay on?

You can't.

Why do you want to? Just curious. Seems like a waste of energy/battery life.
