What is the monitor and its type?
Do you know what a computer monitor is? 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 like gaming, watching movies, 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 varieties of desktop computers available in them using the use of technology like CRT monitors to latest slim LCD, LED and OLED monitors.
There are several parameters to measure the performance of a monitor such as luminance, contrast ratio, resolution, dot pitch, response time, refresh rate and power consumption. Together, the common problems that often occur in monitors are those of dead pixels, blurred screens, phosphor-burn etc. So today I thought why not give people information about the monitor. This will allow you to know what you do 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 which 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 a television tuner in the monitor, to change the channels, the same happens in the television. Monitors have a higher display resolution than television. A high display resolution facilitates viewing small letters and fine graphics.
A monitor is known by names such 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.
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 images 1s and 0s into images, images can be easily and directly displayed in a connected monitor.
Therefore, the main function of Computer Monitor is to display video and graphical information that is generated from a computer’s graphics adapter. This gives the user the facility 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).
Types of computer monitors
There are many types of Computer Monitors to use Mehjud. Here I am going to tell about some types of monitors which were used before, some are still being used. Then let’s know more about them.
These monitors use a cathode ray tube to display images. To manufacture this cathode ray tube, a vacuum tube, heaters, electron guns, deflection circuits and a glass screen are used. When electrons are produced inside the cathode ray tube, then the screen is bombarded by these electrons, by which they glow and images are produced. CRT monitors resemble old television sets. They are bulky and consume a lot of energy together.
These LCD screens use monochrome pixels to project images. These pixels are systematically arranged between the transparent electrodes and polarizing filters. Images are form when the pixels are polarized. LCD monitors consume very little energy and provide a much better graphics quality. Most computer monitors that we use now have Liquid Crystal Display. The screen sizes range from 17 inches to 60 inches.
LED monitors are very recent types of monitors that are now available in the market. These are flat panels, or slightly curved displays that use light-emitting diodes, for back-lighting, cold cathode fluorescent (CCFL) back-lighting is used in LCDs. LED monitors use very little power compared to CRT or LCD. Apart from this, they are also more environmentally friendly.
The advantages of these are that they produce such images in which there is a high contrast, and together they do not even put negative environmental effects when it is dispose, and it is 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 technology is another latest technology of display devices. The basic idea behind it is that it illuminates the tiny colored fluorescent lights that create image pixels. In it each pixel is made of three fluorescent lights – which are red, green and blue lights. By which many colors of variety are produced, along with it also vary in intensity of these lights accordingly.
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 so capable they can produce different color light, so they can be used directly to produce correct color and there is no need of backlight in it so that it 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.
Latest Display Technology’s Advantages Above conventional display technologies:
There are many functions of Conventional Display Technologies, which can be completed 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 that 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.
