A method of displaying data or images on a multi-level screen display, assigns screen designation codes to respective software components, to determine the physical screen on which the corresponding images or software components are displayed. The screens may include layered liquid crystal displays. The method allows a user to see overlaying objects at the same time, e.g., toolbars or menus can be displayed on a front screen, and a drawing image can be displayed on a background screen.
