TYPES OF COMPUTER MONITOR

TYPES OF COMPUTER MONITOR

1. Monitor CRT

Monitor CRT

CRT (Cathode Ray Tube) is a kind of old monitors are popular and commonly found on older computers, for now the use of CRT monitor type is not used much anymore considering has been the emergence of new technologies such as LCD monitors and plasma quality and ability is much better.   CRT works by emitting cathode rays (electrons) high speed inside the vacuum tube. Next emission from the cathode ray will memanulkan screen that is flouroscent (when wearing fluorescent light).   The reflection of electrons or the cathode to form a pattern on the screen, and while the cathode ray will continue to reflect the screen according to the input that has previously been in the conversion into an electromagnetic wave.   Adapaun advantages of using a CRT monitor types is the price that is cheaper and economical when compared to other types, while some of the disadvantages of using a CRT type monitor is power consumption is high at about 300-400 watts so it is often less convenient for the user's eyes, especially if used in a long time.   To cope with the radiation of a CRT monitor is usually the kind of glass can add additional filters to reduce light radiasai pancarkaan elektormagnetik that in the monitor, so it will also make the user's eyes more comfortable when interacting with CRT type monitor.   The physical size which tend to be large and heavy also become one of the shortcomings of the CRT monitor, it will be take place when the user is wearing it.

2. Monitor Liquid Crystal Display (LCD)

Monitor LCD

Next monitor type of LCD (Liquid Crystal Display) monitor that is collated using a liquid crystal display that can deliver quality color dihasilakannya which is much better than the CRT type monitor.   LCD monitor technology types have more light, or we are familiar with pixels consisting of a single liquid crystal as a point of light. Although referred to as a point of light, this liquid crystal does not emit light. The light source in an LCD device is a white fluorescent lights at the rear of the liquid crystal composition earlier.   Points of light or pixel numbering tens of thousands or even millions will be formed in the image display. Polar liquid crystals through which electric current will change due to the influence of magnetic field polarization arising and therefore will only let a few colors forwarded while other colors are filtered.   Some of the advantages of LCD monitor type is the picture quality looks more clear and sharp and more comfortable to the user's eye keetika use it, not only that the LCD is also more power efficient, more tips are physically and easier in terms of display settings.   While some deficiencies LCD monitor type is more sensitive cendeurung screen and limited viewing angle and color depth is limited and certainly more expensive than the type of CTR.

3. Monitor LED (Light Emiting Diode)

Monitor LED

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, power usage is much more efficient than the LCD, a longer service life, 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

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 a superb color as well as shape look slimmer.   In terms of shortages of course plasma have a price relatively expensive, so often users still prefer 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

enis Monitor OLED (Organic Light-Emitting Diode) is a semiconductor as a light-emitting layer made of organic. 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 is actually not overly used by computer users considering the price is relatively 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.
