Technology - what is computer monitor and types of monitor
Monitor
Monitor is an output device. This is also called a visual display unit. This is like watching TV. Monitor is one of the most important output devices. Without it the computer is incomplete. It displays the output as a soft copy on its screen. These are of three types depending on the colors displayed by the monitor.
Monochrome
This word is made up of two words mono (i.e. Single) and chrome (i.e. color) which is why it is called single color display and it displays the monitor output as black and white |
Gray-scale
These monitors are like monochrome but it displays any type of display in gray shades. These types of monitors are mostly used in handy computers such as lap tops (Laptop).
Color Monitors
Such monitor displays the output as the adjustment of RGB (Red-Green-Blue) radiation, due to the theory, such monitors are capable of displaying graphics in high resolution, at the same time as the memory of computer memory such monitor 16 Ranging from 16 million to the display of the output.
Types of Monitor
- CRT Monitor
- Flat Panel Monitor
- LCD (Liquid Crystal Display)
- LED ( Light Emitting Diode)
CRT Monitor
CRT Monitor is the most commonly used Output Device, also called VDU (Visual Display Unit), its main part is cathode Ray tube, which is called Generally Picture tube. Most of the monitors have Picture Tube Elements, which are TVs. This tube is similar to the set. Is called CRT The technique provides output in affordable and colorful colors. CRT has an Electron gun, which emits electrons beam and cathode rays, it is passed electron beam, Electronic grid, so that electron speed can be reduced CRT Monitor Phosphorus is screened on the screen, so as soon as the electronic beam strikes the screen, the pixels are shining and the image or layout appears on the screen.
LCD (Liquid Crystal Display)
With the development of technology, the Monitor also changed its way with the development of CRT Monitor, and in the exchange of the CRT Monitor, LCD Monitor has come into vogue now. Monitor is very attractive. Also known as Liquid Crystal Display, LCD. It is Digital Technology which creates a shape through a liquid crystal on a flat surface, it takes less space, it takes less energy and produces less heat than conventional Cathode ray tube monitors. This display is first used in the Laptop. Breakfast was, but now it seems to be used to screen Desktop Computer
Flat panel Monitor
This technique was developed in place of CRT technology, in which chemicals and gases are placed in a plate and used in the display. It is a very thin screen. Flat Panel is light weight and reducing power consumption, in which Liquid Crystal Display-LCD technology is used. LCDs have less clarity than CRT technology, they are used in Use Laptop etc.
Monitor Signs
There are special features inside any type of monitor, depending on which quality is tested. The main symptoms of monitor are resolution refresh rate do not pitch interlacing non interlacing bit mapping, depending on which quality is tested.
Resolution
Significant attributes of the monitor - Resolution This illustrates the clarity of the picture's Picture (Picture), in most Display Devices, the small screen of Small Screen (Dots) These small small dot pots of the screen are called pixels. Here the pixels are the short form of the Picture Element. The more pixels on the screen, the resolution of the screen is equally a That will that image (Image) will be equally clear is composed of a display resolution (Resolution) to be 640 * 480, this means that the screen column of 640 dots (Column) and rows of 480 dots (Row) |
Refresh Rate
The monitor continues to work. The image on the computer screen keeps on removing the left and right from top to bottom. Which is arranged with electron guns. We can only experience this when the screen is clicked or when the refresh rate is low. The refresh rate in the monitor is measured in Hartz.
Dot Pitch: - A type of data pitch is technical. Which displays it. What is the horizontal difference or distance between the two pixels. It is measured in millimeters This reflects the quality of the monitor. Datapitch should be low in monitor. This is also called a phosphor pitch. The color pointer of color monitor ranges from 0.15 MM to 30mm.
Interlacing or non Interlacing
This is such a display technology. Which increases the quality of the resolution in the monitor. The electron gun used to draw only half line in the intrusion monitor because the introderator monitor only refreshes only half the line at a time. This monitor can display more than two lines in each refreshed bicycle. It was only lacking that it was slow to slow down. The resilience of both types of monitor is good. But the nan intrusion monitor is much better
Bit mapping
Only the managers used to be able to display the tex were limited and their number of pixels was limited. Where Tex was manufactured. The technique used to develop graphics in which texts and graphics can both be displayed, it is called bit mapping. In this technology bit map graphics are controlled by each pixel's apparatus. This allows the operator to make any shape on the screen.
Video Standard or Display Modes
Video standard refers to the technique used in the monitor. The video technology of personal computer is improving day by day. Following are the few examples of standard video standards
- Color graphics Adapter
- Enhanced Graphics Adapter
- Video graphics Array
- Extended Graphics Array
- Super Video graphics Array
