You will need to clarify this question to get a good response.
Remember that the BB only displays one screen at a time, each screen is pushed onto the display stack and popped off the stack when closed.
Also you must distinguish between a Screen - which is the Fields/Controls you want to display, and the Display, which is the actual LCD. Also note that Screens contain Managers to manage the Fields and Managers contain Fields, which is what is actually displayed.
Can you restate your question, perhaps with an example?
