Display 对象表示一个连接到系统的物理显示。 一个伪 Display 可能存在于无图形界面（Gui）系统上, 或者 一个Display 可能与一个远程的虚拟显示相对应。

Display Object

• id Number - Unique identifier associated with the display.
• rotation Number - Can be 0, 90, 180, 270, represents screen rotation in clock-wise degrees.
• scaleFactor Number - Output device's pixel scale factor.
• touchSupport String - Can be available, unavailable, unknown.
• monochrome Boolean - Whether or not the display is a monochrome display.
• accelerometerSupport String - Can be available, unavailable, unknown.
• colorSpace String - represent a color space (three-dimensional object which contains all realizable color combinations) for the purpose of color conversions
• colorDepth Number - The number of bits per pixel.
• depthPerComponent Number - The number of bits per color component.
• bounds Rectangle
• size Size
• workArea Rectangle
• workAreaSize Size
• internal Boolean - true for an internal display and false for an external display

The Display object represents a physical display connected to the system. A fake Display may exist on a headless system, or a Display may correspond to a remote, virtual display.
