The Screen tab present in the right panel has the Draw area in which the developers can drag and drop the bean components and build their applications. The Screen tab consists of two panels.
The top panel is the Draw area is for visible bean components and the bottom panel, in white, the 'Invisible bean area' is for invisible bean components. Visible beans are visible in the screen and they have user interface. Invisible beans are represented by a rectangle in the screen and does not have a user interface.
The below image shows the Screen view with visible components in the Draw area and an invisible component in the Invisible Bean Area.

Although the screen area is demarcated between visible and invisible beans, you can place the invisible components anywhere on the screen. While running the application or applet, only the visible beans are displayed. However, if the visible components are placed in the 'Invisible bean area', they are not displayed during runtime.
