A [=/screen=] has a label, which is a string that meaningfully describes the screen to a user.
-Note: The [=screen/label=] can be an arbitrary string selected by the user agent. It could describe the screen relative to the device, e.g. `"internal"` vs. `"external"`, it could include the dimensions, e.g. `"640×480"`, it could include hardware model information, e.g. `"Acme Telletube 1000x"`, it could include a distinguishing number, e.g. `"screen 1"` vs. `"screen 2"`, or all of the preceding.

The label can be an empty string if underlying display details are unknown or the user agent chooses to hide that information.
Advisement: While many screen attributes could be used for [=/active fingerprinting=], the strings used as [=screen/labels=] in particular should be considered carefully to minimize the uniqueness. For example, it would be a poor choice to include the serial number of the device.
