Types of Monitor
The different types of monitor are as shown below:
- Cathode Ray Tube Monitors: are those monitors that were used in earlier versions of computer. They are heavier and consume more energy. These monitors produce images through manipulation of electronic beams.
- LCD: stands for Liquid Crystal Display. These monitors are thinner as compared to Cathode Ray Tubes. They have higher resolution, consume less energy and take up less space.
- LED: stands for Light Emitting Diode. As the name suggests it uses light emitting diode for backlighting. LED Monitor provides upto 4K resolution and is much more environment friendly as it consumes less energy.
- OLED: It stands for Organic Light Emitting Diode. It uses organic materials to convert electronic current to light. Organic materials include wood, plastic, polymers etc. These monitors are foldable as compared to traditional LCD or LED. It is thinner and is excellent for watching movies. However its lifespan is very less and are expensive.
What is a Monitor?
During ancient times, before the introduction of monitors, devices like Abacus and mechanical calculators were used. After the development of the Analytical Engine by Charles Babbage, the theory of computers came into existence. Now the latest computers comprise basic components like Output Devices, Input Devices, RAM, ROM, CPU, Motherboard, Hard Disk Drives, Cooling Systems, etc. Output Devices are components of the computer. It converts electronic data to a readable format. This readable format can either be displayed to the user as end result or can be used by any other equipment. Some examples of Output Devices are monitors, printers, speakers, headphones, projectors, etc.
