# About graphic displays

In FactoryTalk View Studio, there are three kinds of graphic displays:

- Standard displays - stored in the Displays folder. These are the displays that the operator sees at run time. They present views of automated plant activity or processes. They can show system or process data and provide operators with a way to write values to a real-time database or an external device such as a programmable controller.
- Global object displays - stored in the Global Objects folder. Global object displays let you link the appearance and behavior of a graphic object on a global object display to multiple copies of that object in standard displays. When you make changes to the original object, the changes are automatically applied to the copies.
- Library displays - stored in the Libraries folder. A library display contains ready-made graphic objects that you can use in other displays.

The elements that make up a graphic display are called graphic objects. The Objects menu in the Graphics editor provides simple drawing elements such as line, rectangle, and ellipse, as well as ready-made objects such as push buttons, input and display fields, and alarm banners and lists. Use these elements to create visual representations of processes and activities. Then animate the display by linking objects to tags so that the appearance of the objects change as the values of the tags do.

The maximum number of displays an application can have is determined by the type of activation the user has purchased for FactoryTalk View Studio. PanelView Plus 7 Standard applications have a limit of 100 displays (50 On Top displays and 50 Replace displays). Compact Machine Edition applications (applications running on PanelView Plus 6 Compact or PanelView Plus Compact terminals) have a limit of 25 displays.
