Samsung SCH-A950

it seems that some people on here have the opposite problem i do. can anyone tell me if the external lcd screen (a950) can be set to be blank until you press a button? i want a picture to be on it, but not visible at every second. i have my backlight set to 5seconds but when it shuts off, a bright picture is still on that front lcd. is that just the way the phone is? it practically has my whole room bright while im trying to sleep...
