Evolution of Monitor

~~~ Monitor ~~~


A monitor or a display is an electronic visual display for computers.The computer monitor, also known as the visual display unit, displays the images created by a computer.In recent years, monitors have evolved at a rapid speed that has seen quality go up and prices go down.


Evolution:

Cathode ray tube (CRT) monitors

CRTs dominated the PC monitor industry for over 20 years since 1980s. CRT monitors use magnets and cathode ray emitters to produce pictures on a screen. Because of this, they have to be relatively large and heavy. CRTs are reliable and inexpensive; but they are extremely heavy and take up a lot of space.


Liquid Crystal Display (LCD) monitor


By the early 2000s, LCDs had effectively replaced CRTs as the dominant PC.LCD monitors have become the standard in computer monitors for laptops and desktop computers. The advantages of LCD monitor are lighter and it has long service life.




Plasma Monitor
Plasma monitors are not commonly used as computer monitors because of their expense, weight, power consumption and size. However, they offer a wide range of contrasts, colors and have a long display life so it can be used for years without going dead.



Touchscreen Monitor

Touchscreen monitors are built by combining touch-sensitive materials.The touchscreen enables user to interact directly with what is displayed, rather than using a mouse or any other intermediate device.




Organic Light Emitting Display (OLED) Monitor



OLED displays are extremely thin and light and offer the promise of portable, lightweight displays. OLED technology is still new, the price of OLED monitors is much more expensive than traditional CRT or LCD monitors, and the life of the monitor is relatively low.
