Since the touch screen is off, it isn't listening for events, so that won't work. If the touchscreen (not even display) were always on and listening, it would obliterate any chance of good battery life. Also, I assure you that you don't actually want to do what you just said, even if you could. A double tap would invariably trigger while the phone is your pocket, and have the same result -- killing the battery. – Jameson Nov 15 '15 at 13:36
