Difference between Display Object and Display Object Container
In ActionScript 3.0, anything that appears on the application screen are types of display objects and display object containers are special types of display objects. Though both are visually represented in the application in the same way, the difference between them is that one can add child display objects to a display object container. That means, you can use a Sprite as a display object container and can add shapes, bitmaps, texts,… as child display objects.
