They are flat screen and are much skinnier than the CRT. The LED monitor is the newest type of monitor on the market. The LED is also a flat screen like the LCD monitor but uses different technology than the LCD. All three monitors share the same purpose but what are their differences?
The CRT monitors, also known as “Cathode Ray Tubes” are the monitors of the past, but still used by companies today. CRT monitors are big monitors looking like old TV’s. They use three electron guns to beam three electrons beams the color of red, blue and green. These beams are then focused by focusing coils to display the colors and pictures on a fluorescent screen.

They are bright but not as bright as LCD or LED monitors. Also, older CRT monitor’s screens are rounded, but newer CRTs are flat screened.
The LCD monitor also known as “Liquid Crystal Display” monitors are newer in the market, but not the newest. LCDs work by blocking light emitted by backlight.

The viewing angle of the LCD is very bad and you have to view it straight on to have a comfortable feeling. The lower end ones can also have a slower response time.
The LED monitor, also known as “Light Emitting Diodes” monitors are the newest in the markets. LED monitors function like LCD’s except they use LED lighting rather than cold cathode fluorescents. There are many advantages to the LED monitor. They use less energy than any other monitor meaning if you are using an LED monitor, your electricity bill would be cheaper. They also have less impact to the environment when you get rid of it. Also, LED monitors have a longer lifespan than CRT and LCD monitors. And, the LED monitor is very thin and light weight. The disadvantages to the LED monitor are they are very expensive. Also, like the LCD monitor, it would be uncomfortable to view the LED monitor at an angle.
