CRT (Cathode Ray Tube) Monitor

CRT discovered by German physicist Ferdinand Braun in 1897 and became known as the "Braun Tube". CRT is a vacuum tube containing an electron gun and a heating element (heater), which serves to accelerate and deflect the electron beams. This is because in a vacuum hot, the electron beam is easy to move from the cathode toward the anode.
