What is a Monitor? | How the Monitor Work | CRT, LCD, LED, Plasma And OLED Monitor

Do you know what a computer monitor is? Perhaps you've heard about it. Because we are all very familiar these computer monitors. We spend most of our time sitting in front of these monitors, such as gaming, seeing movies. Similarly, monitors are used like a display unit in Computer system.

A good display can have too much effect pulse sein experience any user. The qualities of display devices has also become very improve with the innovation in the Display Technologies. Now desktop computers are getting a lot of variety, from the use of technology, such as CRT monitors to latest slim LCD, LED and OLED monitors, etc.

There are many parameters to measure a Monitor's performance such as luminance, contrast ratio, resolution, dot pitch, response time, refresh rate and power consumption. The common problem that are often generated at the same time are dead pixels, blurred screen, phosphor-burn, etc. in monitors. So today I wondered why you should neither inform people about what a monitor is. This will also let you know what you don't know. Then let's start without delay and know the Computer Monitor.

What is a Monitor ?

Computer monitor is called technically visual display unit. It is a output device that show in Monitor Screen in all information of CPU. It happens like a interface between CPU and user. A cable is connect with video adaptor or with video card that is set up with the motherboard of computer.

What is a Monitor? And type of computer monitor?

Monitors look very similar with televisions. The main difference that occurs in both of them is not television tuner in the monitor channels to change, the same happens in the television. Monitors higher display resolution than television. A high display resolution facilitates small letters and fine graphics to view.

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

Who invented the Monitor?

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

What works Monitor?

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

Therefore, Computer Monitor has a main function display video and graphical information that generate graphics adapter computer. This allows user to interact with computer. It is categorized according to a output device. A monitor is a very important part of the whole computer system. It is sometimes called video display unit (VDU).

Different types of Monitors

Lots of Computer Monitors are types mehded to use. Here I am going to mention about the Monitors of some types that were used earlier, some are still being used. Then let's know more about them.

CRT Monitors

This monitors uses a cathode ray tube to images display. A vacuum tube, heaters, electron guns, deflection circuits and a glass screen are used to construct this cathode ray tube. When electrons produce within the cathode ray tube, the screen is bombard by these electrons, making them glow and images produce. let's resemble CRT monitors older television sets. They are bulky and do a lot of energy consume at the same time.

LCD Monitors

They use LCD screens monochrome pixels to project images. These pixels are systematically arrange between are transparent electrodes and polarizing filters. Images form occur when pixels polarized.

LCD monitors consumption very little energy and provide much better graphics quality. Most computer monitors we use now use Liquid Crystal Display. The range of screen sizes varies from 17 inches to 60 inches.

LED Monitors

LED monitors are monitors of the very latest types of the present time which are now available in market. These are flat panel, or slightly curved displays that use light-emitting diodes back-lighting, the same cold cathode fluorescent (CCFL) back-lighting is used in LCDs.

Very few power are used in LED monitors as compared to CRT or LCD. They are also more environmentally friendly.

The advantages of this is that they images produce that have higher contrast, and at the same time, they don't put much negative environmental impact when it is dispose, and they are also more durable than CRT and LCD monitors.

Their design is also very thin. They don't create much heat. The downside is that they are more expensive.

Common types of Active Matrix LCD panels:

IPS Panels

In-Plane Switching panels were created to solve the poor viewing angles and low-quality color of the TN panels.

They are more commonly used in professional environments because the refresh rates aren’t the best for gaming.

But when it comes to image quality, it delivers great results. And, it comes with a little extra on the price.

The response times are faster than VA panels but slower than the TN panels.

TN Panels

Twisted Nematic panels are the most common purchased by consumers. They deliver reasonable response times at a reasonable price.

Plasma Monitors

Plasma technology is another latest technology display devices. The basic idea behind it illuminate tiny colored fluorescent lights that image pixels create.

Each pixel are made up of three fluorescent lights – red, green and blue lights. Which creates many variety color, as well as intensity of these lights vary accordingly.

OLED Monitors

"OLED has a full form Organic Light Emitting Diode."

It is also a latest technology of display devices. As the name suggests, it is made up of organic material (such as carbon, wood, plastic or polymers), which are used to convert electric current in light. 

Since these LEDs are capable enough to produce different colored light, they produce can be used directly correct color and it does not require any backlight to protect 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 ever.

Above the advantage conventional display technologies of the latest display technology:

Conventional Display Technologies has many things that can be completed using Latest Display Technologies. Let's learn about some such advantages.

• their fabrication process is much easier and display devices is much thinner than conventional display devices.

In • LCD devices comparison, OLED displays can be viewed angles differently because they are devices "emissive" so that they emit light and not transmitted or reflected light them modulate.

• she doesn't use backlight.

• their driving voltage and total power consumption are very low as compared to other display technologies.

• the material that is used are eco-friendly and do not use lead or harmful materials anything like that.


And there you have it. You know what a monitor is, and more than that, what the different types are.

I hope you enjoyed the information and knowing more about them.
