• Display Driver Component
  The Display Driver component (also known as the Display Channel Driver) is new in Symbian^3 and is for use in ScreenPlay only. The Display Driver component includes a reference implementation, which a composition implementation can use to display the composited output on the screen without tearing. However, the use of the Display Channel Driver is optional. Implementers of the Composition Interface are not required to use it.
• Surface Manager Component
  The Surface Manager component manages the lifetime and use of graphics composition surfaces in system memory.
