Gray-Scale: A special type of monochrome monitor capable of displaying different shades of gray.
Color: Can display anywhere from 16 to over 1 million different colors. Sometimes called RGB monitors.
Monitor Quality:-
Manufacturers describe quality by dot pitch.
Smaller dot pitches mean pixels are closely spaced which will yield a sharper image.
Most monitors have dot pitches that range from 0.22mm to 0.39mm.
Monitors (Display Screens)
Monochrome monitors
Composite monochrome monitors
Composite color monitors
TV sets
RGB monitors
VGA mono monitors
VGA color monitors
Advantages of CRT:-
The cathode rayed tube can easily increase the monitor’s brightness by reflecting the light.
They produce more colours
The Cathode Ray Tube monitors have lower price rate than the LCD display or Plasma display.
The quality of the image displayed on a Cathode Ray Tube is superior to the LCD and Plasma monitors.
The contrast features of the cathode ray tube monitor are considered highly excellent.
Disadvantages of CRT
They have a big back and take up space on desk.
The electromagnetic fields emitted by CRT monitors constitute a health hazard to the functioning of living cells.
CRTs emit a small amount of X-ray band radiation which can result in a health hazard.
Constant refreshing of CRT monitors can result in headache.
CRTs operate at very high voltage which can overheat system or result in an implosion.
Within a CRT a strong vacuum exists in it and can also result in a implosion.
They are heavy to pick up and carry around.
