- * Manages the properties, media routing and power state of attached displays.

- * The display manager service does not own or directly control the displays.
- * Instead, other components in the system register their display adapters with the
- * display manager service which acts as a central controller.
+ * The {@link DisplayManagerService} manages the global lifecycle of displays,
+ * decides how to configure logical displays based on the physical display devices currently
+ * attached, sends notifications to the system and to applications when the state
+ * changes, and so on.
+ * </p><p>
+ * The display manager service relies on a collection of {@link DisplayAdapter} components,
+ * for discovering and configuring physical display devices attached to the system.
+ * There are separate display adapters for each manner that devices are attached:
+ * one display adapter for built-in local displays, one for simulated non-functional
+ * displays when the system is headless, one for simulated overlay displays used for
+ * development, one for wifi displays, etc.
+ * </p><p>
+ * Display adapters are only weakly coupled to the display manager service.
+ * Display adapters communicate changes in display device state to the display manager
+ * service asynchronously via a {@link DisplayAdapter.DisplayAdapterListener} registered
+ * by the display manager service. This separation of concerns is important for
+ * two main reasons. First, it neatly encapsulates the responsibilities of these
+ * two classes: display adapters handle individual display devices whereas
+ * the display manager service handles the global state. Second, it eliminates
+ * the potential for deadlocks resulting from asynchronous display device discovery.
+ * </p><p>
+ * To keep things simple, display adapters and display devices are single-threaded
+ * and are only accessed on the display manager's handler thread. Of course, the
+ * display manager must be accessible by multiple thread (especially for
+ * incoming binder calls) so all of the display manager's state is synchronized
+ * and guarded by a lock.
