Pengertian Monitor Dan Jenis-Jenisnya

Monitor is one of the computer hardware that is used to display the output results of the processing performed by the graphics card or the computer's memory so it can be viewed by the user, whether it be the data view text, images, and video. Well, here are the types of monitor you need to know, namely:

1. Monitor CRT (Cathode Ray Tube)

Maybe this monitor can be categorized in the category of old school monitor. Why is that? Because this type of monitor is long enough to fly in the world of electronics. Display monitor emission generated from high-speed electron beam in a vacuum tube. Then the beam of cathode ray screens this will pound that is flouroscent (fluoresce when subjected to light). The collision of electrons or the cathode to form a pattern on the screen. Meanwhile, the cathode ray will continually pounding the screen according to the input that has previously been converted into units of electromagnetic waves.

The advantage of using this type of monitor is a relatively cheap price. In addition to having the advantage, CRT type monitor also has the disadvantage of a large enough electrical power usage of about 300-400 watts and eyes get tired because of the emission of electromagnetic radiation exposed to this type of monitor.

2. Monitor LCD (Liquid Crystal Display)

LCD Monitor is a media type that uses liquid crystal display as the main ingredient. LCD type is already very popular used in many electronic goods such as televisions, computer screens, calculators, etc. Currently the LCD screen has been dominating for notebook or laptop because it requires low power, very light weight, thin shape, the heat generated little and has high resolution.
An LCD consists of many pixels which are the fruit of a liquid crystal as a point of light. Although it is called a point of light, the liquid crystal was not able to emit light. Light produced by an LCD sourced from a fluorescent lamp that has a white color which is located at the rear of the liquid crystal composition earlier.
The advantage of using this LCD monitor is in addition to the model is sleek and does not take place, another advantage is the highly-efficient LCD monitors use about 20 watts of electrical power and low radiation. The disadvantage is the type of LCD monitor prices are relatively more expensive, and in case of damage the LCD monitor is much more expensive in terms of spare parts than any CRT monitor. Monitor type LCD is also vulnerable because it is easily scratched, dead pixels, so that the position of the pixel leaked image can not be displayed.

3. Monitor LED (Light Emiting Diode)

The monitor type LED (Light Emitting Diode) technology with nearly the same as the LCD. LED is a further development of LCD display which has the effect of an increase in color display that has a quality and more color variation.
Some types of LED monitors have a function and the more advanced features in the appeal as their type of LCD monitor touch screen technology, the internet and digital TV Digital TV tuner. LED monitors are also considered to be able to save the power consumption up to 40% -70% if compared to the LCD with the ability to produce extremely sharp images. Some of the advantages of LED monitors is such a contrast, sharp images up to millions of pixels, use much less power efficient than LCDs, the service life is longer, more slim and better lighting in the appeal monitor LCD type. In terms of types of LED monitors shortage of course the price is still relatively more expensive that many users who still prefer CRT type monitor or LCD, LED monitor shortfall next is likely to be more sensitive.

4. Monitor Plasma

Type plasma monitor is a combination between CRT and LCD technology. The presence of plasma monitor is able to make the screen becomes thinner resemble LCD and CRT-wide viewing angle. Some of the advantages of plasma monitor type is found in the quality of which resembles a CRT display with a high contrast is 10000: 1. Besides plasma also has excellent color and shape look slimmer.


In terms of disadvantages, of course, the plasma has a relatively expensive price, so that users often still choose to use the old type monitor it more affordable, than that of plasma also has a large pixel pitch size and power consumption and high temperature operasioanl. How it works plasma monitor is a flat-screen emisif where the light is generated by phosphorus detected a plasma discharge between two flat screens. The released gases do not release mercury. Type plasma monitor using a full color flat panel phosphor to display images and color reproduction so the combination that produced very good's qualitative and interactive.

5. Monitor OLED (Organic Light-Emitting Diode)

Monitor Type OLED is a light-emitting semiconductor as made from the organic layer. OLED itself is used in technologies such elektroluminesasi on screen display and sensor applications, is famous for its technological sophistication over felxibel with attenuation of less than 1 mm.


OLED created from structures consisting of layers of glass made of tin oxide-indium as the positive electrode, or anode, an organic layer of diamine aromatic having a thickness of 750 nm, a layer of light-emitting made of compound metal complexes such as 8-hydroxyquinoline aluminum and electrode layer negative or cathode is made from magnesium alloy and silver by atomic ratio of 10: 1. Overall construction layer is not more than 500 nm, which means that the same OLED thin sheet of paper.


The use of OLED monitor is still very rarely used, because the price is still quite expensive. OLED monitors are widely used in mobile phone technology such as the latest smartphone that the screen uses OLED technology where pixels are supported approximately 16 million colors that make images or the results of the resulting photo looks very clear, sharp as if it looks like the original image.
