What Is Monitor And What Is Its Full Form?

A computer monitor is an electronic device that is also called a visual display unit. It consists of a screen, a circuit system, a power supply, buttons for screen settings, and a casing inside which the entire circuit is installed.

Many people do not know what the display used on the computer is called. Many people consider it only a means of entertainment. Today we thought of telling you what a computer monitor is. And what are its functions?

If this question has come to your mind then it is good because you will get the answer in this post.

Nowadays, all types of display technology include the use of Super LCD 3 and Super AMOLED, even if the display is a mobile or television display.

What is a computer monitor, and what is its specialty? We will know through this post, if you like the post, then share it with your friends.

Introduction To Monitor

A monitor is also called an output device because it shows all the information on the computer screen. The monitor is connected to the central processing unit, which displays every movement of the user on the screen at the same time as the work is done. 

For example, whatever data we input through the mouse and keyboard, we can only do it by seeing it in this output device. A monitor is an output device that shows us information in the form of text, images, and video.

Earlier, cathode ray tubes (CRT) were used to make monitors, due to which they are very large and their weight is also high.

But nowadays, flat-screen LCDs are used a lot, whether it is a laptop, PDA, or computer monitor.

Which is also called flat panel display technology. Such display devices have become very light and thin in weight, they can be carried very easily, and they run on very little power.

Computer monitor definition in English 

A monitor is an electronic device that is called the output device of a computer system. It works as an interface between a user and a CPU. It shows all the information in the form of text, images, and video. It is also called a Visual Display Unit, or VDU.

Definition of the monitor in Hindi 

It is an electronic device that is also called the output device of the computer system. It works as a medium between the user and the central processing unit.

It shows us information on its screen in the form of photos, text, and videos. It is known as the Visual Display Unit, which is abbreviated as VDU.

What Is The Full Form Of Monitor?

Well, the word monitor has its meaning, which means a device that shows or displays. There are many types of it which have short names and also have full forms.

Well, if we say it like this, then its full form is:

M: Machine

O: Output

N: Number of

I: Information

T – To

O: Organize

R: Report

CRT Monitor – Cathode Ray Tube

Liquid Crystal Display

LED – Light Emitting Diode

Who Invented The Monitor

The cathode ray monitor was invented by Karl Ferdinand Braun.

He invented it in 1897 AD when he created the cathode ray tube for the first time. He was a German scientist.

How Does A Monitor Work?

A monitor is a visual output device that is a very important part of the computer. It shows us pictures, images, and written words in real-time.

With the help of this, a user can interact with the computer and can open and work on any application as per his wish.

Friends, you already know what it does. If you don’t know, then today you should know that the main function of the monitor is to display, That is why it is also known by different names like screen, display unit, visual unit, video display, video screen, etc.

A video graphics card is installed on the computer. This graphic card converts the information and displays it in visual form on this device.

Whenever we input any data with the help of an input device, it goes to the CPU, and after being processed from there, it sends it to the output device, i.e., the monitor, to display it in the CPU.

Features Of Monitor: Features In Hindi

Today you are surrounded by a new market where you often hear new words related to monitors like LCD, OLED, TN, IPS, etc.

But today, people must be asking you what size the monitor is in your house. So does your device also have 1080 resolution, and do you need a 4K or 5K display?

Do you want to set up dual monitors? People choose their devices based on many such features. So let’s see some of its special features.

Monitor Size

You must have heard that bigger is better. Now very good quality displays come in Full HD (1920 * 1280) size.

The time when people used to work on 15-inch displays is rapidly being left behind. Instead of this, larger-size displays have started being used.

Display Resolution

With the increase in display size, the most important feature is good picture quality, For this reason, 4K-range devices have started appearing in the market. 27-inch 16:9 4K Ultra HD displays are being used.

Panel Type, Viewing Angles

If we talk about display, there are many types of panels.

  • TN-Twisted nematic,
  • IPS- In-Plane Switching),
  • MVA: Multi-domain vertical arrangement,
  • PVA-patterned vertical arrangement,
  • SPVA (Super PVA) is quite famous.

There are some displays whose viewing angle is as low as 90/60 degrees, and some are as high as 170/180 degrees.

Aspect Ratio

Till some time ago, the aspect ratio of 4:3 was used, but now those days are gone, nowadays, no one likes such displays.

Monitors with a 16:9 aspect ratio are the most comfortable and also a lot of fun to work on.

What Are The Types Of Monitors? Types Of Monitors in Hindi

Most people use desktops to work in their offices and homes. Nowadays, there are many types of monitors on the market that come in different shapes, sizes, and designs.

Here we will know how many types there are and how they are different from each other. So let us know in detail.

CRT (Cathode Ray Tube)

CRT technology is used in this type of monitor. Cathode-ray tube technology is also used in making television screens.

A stream of very high-energy electrons is used to show the image in the fluorescent screen of CRT.

A cathode ray tube is mainly a vacuum tube that has an electron gun on one side and a fluorescent screen on the other side.

You must have often seen that in the earlier televisions also a picture tube was used, due to which they are quite bulky and their weight is also very high. It also consumes a lot of electricity to run them.

Even today, there are many organizations where you can see CRT. Their use has now been stopped in many government offices.

The main reason for this is that they are quite heavy and costly, hence, lighter and cheaper monitors are being used in their place.

Liquid Crystal Display (LCD)

LCD monitors are one of the most developed and best devices in today’s time. It is also known as a liquid crystal display or liquid crystal diode.

If we talk about it, it consists of a layer of color or monochrome pixels that are arranged schematically between 2 transparent electrodes and 2 polarizing filters.

To create the optical effect, different amounts of light are polarized and passed through the liquid crystal layer.

In this way, images are formed and visible to us on the screen. Currently, two types of LCD technology are available. One of these is an active matrix or TFT, and the other is a passive matrix.

Recently, LCD monitors have become quite popular and are the first choice of people. The reason for this is that they are compact. These are light in weight.

It does not require much space to keep them on the desk. A big advantage of these is that they do not consume much electricity, and they can also run on batteries.

Light-emitting diode (LED)

Today, LEDs are the newest displays available in the market. Like LCDs, these also have flat panel displays or slightly curved displays.

In this, light-emitting diodes are used for backlighting. Whereas cold cathode fluorescent is used for backlighting in LCDs.

LEDs use less electricity to operate than both CRTs and LCDs. That is why it is also called eco-friendly. These create images in very high contrast. Even after disposing of them, there is not much pollution.

The lifespan of LED is very long, that is, its durability is much greater than that of LCD and CRT. This is such a technology, due to which it is made very thin.

They do not get very hot when they run. If you look at CRTs, they produce a lot of heat, due to which they become very hot. LEDs are a little more expensive than other monitors.

Plasma

Plasma screens, or plasma displays are high-contrast screens that have vibrant colors and brightness.

These make the visual experience even better. It works on the principle of plasma discharge, which is ideally discharged into a flat panel of glass.

This discharge has two compositions: xenon and neon, in which mercury is not used.

A small portion of plasma, or charged gas, is used to illuminate each pixel of the screen.

Plasma displays are thinner in design than CRT displays and are brighter than LCDs.

Plasma displays have almost disappeared from the market. This is because, at this time, LCDs were also available in the market at very low prices. Whereas plasma is much more expensive than LCD,.

SED: Surface Conducted Electron Emitted Display

The full form of SED is the surface-conducted electron-emitted display. These are screens with very high-resolution and flat panel displays.

If some of these are measured diagonally, they are more than 40-inch display units. In SED, colored phosphorus is energized using nanoscopic-scale electron emitters to form an image.

To make this type of display unit, an electron-emitted array and a phosphorus layer are used. A thin sheet between the array and the phosphorus layer helps pass air.

SEDs are displays that consume less power and provide higher-resolution pictures than CRTs.

OLED – Organic Light light-emitting diode

An organic light-emitting diode (OLED) is also an LED display in which an emissive electroluminescent organic compound is in the form of a film.

When electric current is passed through it, it produces light. This organic layer is between 2 electrodes, one of which is transparent.

OLED technology is also used in television screens, smartphones, game consoles, and PDAs.

An OLED display does not require a backlight to function because it produces visible light.

That is why they can be made, and they are being made much thinner than LCD. And they are very light in weight.

Its picture quality is very good. These will become even cheaper in the future. OLEDs consume very little power to operate.

Dual Monitors

Instead of using one big monitor, you can also use 2 separate display units.

This is a feature of the video card used on the computer. By using the video card, we can do some video-related tasks on the computer that we cannot do in the commonly used system.

As the name suggests, it has two display units, which are placed one next to the other. In the form of a clone, the same image is shown in both places.

By using a dual view, one monitor becomes an extension of the other. In which we can move the mouse cursor from one monitor to another.

The clone feature is used in places where there are many viewers, but if the screen is small, then the same video can be shown to everyone by installing multiple output devices.

Using dual-view mode is very beneficial when multiple tasks are being done, like opening multiple windows, spreadsheets, and documents at the same time.

History Of Monitor

Cathode Ray Tube was the first computer monitor that people used to see information about the processes happening inside the computer.

A CRT is a vacuum tube whose one end is coated with phosphorus. When electrons strike them, a light emerges.

At that time, only CRT was available on the market as a display; hence, people used to use it only.

Early computer operators rarely saw text on CRTs, but instead saw colorless vector graphics.

As technology progressed, colorful CRTs were introduced, in which graphics and diagrams along with text also became colorful.

Within a few years, technology advanced further, and personal computers were created with built-in terminals.

These devices could output composite video to inexpensive CCTV monitors. In 1976, Apple company introduced a monitor in front of the people in which the game console can be connected directly to the computer and TV.

CRT used to be heavy and also consumed a lot of energy. In comparison to this, LCD used less energy, and the size was also reduced.

In 2007, LCD replaced CRT and dominated the market.

It was not built in the same year but the work of making it has been going on since 1980. However, at that time LCDs were quite expensive and their performance was also not good.
