for that first you need unlock the screen then update display and again lock the screen. you can lock or unlock screen by using, window.addFlags(LayoutParams.FLAG_DISMISS_KEYGUARD); and DevicePolicyManager lockNow() method.

Actually when screen locks ,your application goes to onPause() but the services of the application keeps running as they runs in background.Hence, to solve your problem you need to wakeup your application for fraction of second then update the screen and then again lock the screen.
