CRT – Cathode Ray Terminals

CRT, or Cathode Ray Terminals, are known as an older style of display type. They use a fluorescent tube and electrons to pain the screen one line at a time.

This lesson discusses CRTs and other types of display devices and examines their specifications and the technologies that support them.

For example, we’ll diagram how a CRT screen is configured and explain how the device delivers display images and why it works that way.  We’ll explain what is met by Red/Blue/Green (RBG), the role of coils in presenting a display, what a “Shadow Mask” is, and why technology has moved away from this display delivery model.
