What is Monitor and its types?

Do you know what is computer monitor ? Perhaps you must have heard about it. Because all of us are very familiar with these computer monitors. We spend most of our time sitting in front of these monitors such as gaming, watching movies and many other things. In the same way the monitor is used as a display unit in the computer system. A good display can be very effective in any user experience. The qualities of display devices have also improved a lot due to the innovation in Display Technologies. There are many types of desktop computers available right now, using technology used in them such as CRT monitors to latest slim LCD, LED and OLED monitors etc.

There are many parameters to measure the performance of a monitor such as luminance, contrast ratio, resolution, dot pitch, response time, refresh rate and power consumption. Also common problems that often arise in monitors are dead pixels, blurred screen, phosphor-burn etc. So today I thought why not give people information about the monitor . You will also be able to know the things that you will not know. Then without delay, let’s start and know in the will of Computer Monitor.

What is Monitor?

Computer monitor is technically called visual display unit. It is an output device that shows all the information of the CPU in the Monitor Screen. It is like an interface between CPU and user. A cable is connected with a video adapter or with a video card that is set up with the computer’s motherboard.

Monitors look very similar with televisions. The main difference between these two is that it does not have television tuner in its monitor to change the channels, while it is in television. Monitors have a higher display resolution than television. A high display resolution provides convenience for viewing short letters and fine graphics.

A monitor is known as screen, display, video display, video display terminal, video display unit, or video screen.

Who invented the monitor?

The first cathode ray monitor was invented by Karl Ferdinand Braun in 1897 when he invented the first cathode ray tube.

What does Monitor do?

A computer monitor is a type of display adapter that displays information processed from the computer’s video card. When a video card or graphics card converts binary information from 1s and 0s to images, then images can be displayed easily and directly in the connected monitor.

Therefore, the main function of computer monitor is to display video and graphical information which is generated from the computer’s graphics adapter . This allows the user to interact with the computer. It is categorized according to an output device. A monitor is a very important part of the entire computer system. It is also sometimes called video display unit (VDU).

Type of computer monitor

There are many types of computer monitors to use. Here I am going to tell you about some types of monitors that were used earlier, some are still being used. Then let us know more about them.

CRT Monitors

These monitors use a cathode ray tube to display images. A vacuum tube, heaters, electron guns, deflection circuits and a glass screen are used to construct this cathode ray tube. When electrons are produced inside the cathode ray tube, the screen is bombarded by these electrons, from which they glow and produce images. CRT monitors resemble older television sets. They are bulky and also consume a lot of energy.

LCD Monitors

These LCD screens use monochrome pixels to project images. These pixels are arranged systematically between transparent electrodes and polarizing filters. Images are when pixels are polarized. LCD monitors consume very little energy and provide much better graphics quality. Most computer monitors that we currently use use Liquid Crystal Display. The screen sizes range from 17 inches to 60 inches .

LED Monitors

LED monitors are the most recent types of monitors which are now available in the market. These are flat panels, or slightly curved displays that use light-emitting diodes for back-lighting, while cold cathode fluorescent (CCFL) back-lighting is used in LCDs. LED monitors use very less power compared to CRT or LCD. Apart from this, they are also more environmentally friendly.

The advantages of this are that they produce such images in which there is a higher contrast, and also it does not make much negative environmental impact when it is dispose, and they are also more durable CRT and LCD monitors. Compared to. Their design is also very thin. They do not produce much heat. The downside of this is that they are more expensive.

Plasma Monitors

Plasma technology is another latest technology of display devices. The basic idea behind this is that it illuminates the tiny colored fluorescent lights that create image pixels. Each pixel is made of three fluorescent lights – red, green and blue lights. Which produces many varieties of colors, along with intensity of these lights also vary accordingly.

OLED Monitors

The full form of OLED is Organic Light Emitting Diode . This is also a latest technology of display devices. As the name suggests, it is made of organic material (such as carbon, wood, plastic or polymers), and is used to convert electric current into light. Since these LEDs are capable enough to produce different colored light, they can be used directly to produce the correct color and there is no need for any backlight, which saves both power and space. . With its fast response time, wide viewing angles, outstanding contrast levels and perfect brightness, these OLED displays are considered to be the best display technologies yet.

Advantages of latest display technology over traditional display technologies:

There are many works of Conventional Display Technologies, which can be accomplished using the latest Display Technologies. Let us learn about some such advantages.

  • Their fabrication process is very easy and display devices are very thin compared to conventional display devices.
  • In comparison to LCD devices, OLED displays can be viewed from different angles because they are ” emissive ” devices meaning that they emit light rather than modulate them transmitted or reflected light.
  • She does not use backlight.
  • Their driving voltage and total power consumption are very low compared to other display technologies.
  • The materials that are used are eco-friendly and do not use lead or some such harmful materials.


I hope I have given you complete information about what is a computer monitor and I hope that you guys have understood about what a monitor is. If you have any doubts about this article or you want that there should be some improvement in it, then for this you can write down comments. With these ideas, you will get a chance to learn something and improve something. If you liked my information about this post monitor in Hindi or you have got something to learn from it, then to show your happiness and eagerness, please share this post on social networks such as Facebook , Google+ and Twitter etc.
