Cathode Ray Tube Technology (CRT)

CRT is an analog device that is used by a digital device - computer. The interface between these two devices is described. The major components of CRT are given below :

Electron Gun

This generates a narrow beam of electrons (cathode rays) which passes through the focusing and deflection systems.

Focusing System

It produces a non-blurred picture by focusing the electrons of the cathode ray into a narrow beam.

Deflection System

Deflection directs the beam towards specified positions on the phosphor-coated screen.

Phosphor-coated Screen

This screen emits a small spot of light at each position contacted by the cathode ray.
