RTC_WAKEUP will not switch on the screen, all it does is wakes up thee cpu so that your job is done. For the Screen to be turned on you need a FULL wakelock to be acquired.

PowerManager pm = (PowerManager)mContext.getSystemService(Context.POWER_SERVICE);
 PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK
                                      | PowerManager.ON_AFTER_RELEASE,
                                      "wakeup");
 wl.acquire();
 // ... do work...
//show toask
 wl.release();
