The difference Plasma TVs with LCD TVs

The difference Plasma TVs with LCD TVs
Television tube model with technology Cathoda Ray Tube (CRT) or cathode ray tubes that have been aged 75 years, gradually been replaced by hi-tech flat-screen TVs LCD or plasma TV.
The biggest drawback of CRT TVs are perceived electronics manufacturer that has reached its size limit. This causes the magnification of the size of the TV means also have to change the dimensions of the tube. TV size 29 inch alone account for a large room especially for the thickness of the tube.
Though the audience requires a large TV for the convenience of the eye. No wonder the tube TV technology is not currently developed.
On the other hand, LCD televisions and plasma TVs have a size smaller. Thickness of the TV is only a few inches that makes it easily placed anywhere in the room. Could stand on the floor, taped like painting on the wall there is even a TV manufacturer could advertise their products on display high on the ceiling.
The main cause of this model is more compact TV is not needed on screen projection unit. Utilizing conventional tube TV technology as a treatment of electron particles. A gun-shaped tool, while the TV is connected to the mains, will shoot a beam of charged electrons or negative atomic particles to the screen. The electron is then captured different screen phosphor layer and the color intensity, so the picture emerges.
DIFFERENT with conventional TVs, LCD TVs use the same technology with a laptop screen or flat screen monitors. In addition to compact size and lightweight also has a higher resolution screen. LCD screen consists of millions of crystals wrapped in a thin glass layer. Each of these crystals have different responses to electrical energy. This is what makes the display on the screen was so varied in color.
Plasma TV screen using the technology in the form of small glass balls that contains a gas called plasma. When energized electrical energy, gas, plasma is out ultraviolet rays that burn the layer of glass on the screen. As a result, the screen changed from black to colorless.
That's the fundamental difference of plasma TV technology with LCD TVs. There are many other differences of both technologies, such as size and flat screen technology.
LCD TVs have limitations in terms of its dimensions, because the LCD is actually designed as a computer monitor. Currently, the largest screen is a Samsung 46-inch size. TV was launched mid-2004, after previously shown at an exhibition of electronic and household appliances in New York, April. Therefore, the size LCD TVs are generally located in the market currently ranges between 15, 17, 20, to 22 inches.
Plasma TVs have a screen size is much bigger, designed for audiences who liked the TV screen above 37 inches. The size of plasma TV can reach 76 inches. So it is not surprising that the fans chose to put together a big screen with your home theater.
But once owners of plasma TVs should be prepared with a soaring utility bills. This is because plasma TVs power consumption doubled from LCD TVs. The main cause is? Is the cooling system of the screen.
Plasma TVs need a fan to 'cool' plasma TV screen that is not too hot when used in a long time. Therefore do not use the combustion process, the LCD screen has a longer life than plasma screens.
FROM the side view the TV picture, both have different characteristics. Screen plasma TVs tend to not able to display black properly. In fact, compared to CRT TVs though, plasma TVs are still lost in producing a dark black color and dark gray shades. Another problem that static images for long periods such as logo of the TV station could not quickly disappear from the screen. Shadow still remains even though the TV broadcast has been moved to other impressions.
In the matter of the quality movement of the picture, plasma TVs have the advantage capable of displaying fast moving images. So the displacement image as an action movie (action) is more comfortable to watch at the plasma TVs. Then viewed from the point of view, plasma TV to have the benefits can be watched from every angle, just like conventional TV.
Usually, plasma TVs sold in the form of video displays, so that remains to be burdened with buying a TV tuner (tuning wave) and speakers.
Conversely LCD TVs are sold complete with speakers and tuner. LCD TV screen has the ability to display a clear black color. To find comfort in watching, eyes must be directed straight at the screen. When viewed from the other side, who looked only a shadow only. LCD TV profits are not require excessive cooling system, so that his voice is more smooth than plasma TVs. So, could be an option for those who need a screen for computer and watch TV.
For those who intend to replace his TV with a large size, some other aspect to consider is contrast ratio, aspect ratio and resolution. Contrast plays an important role in producing images that comfortable to watch. The value refers to the dark or bright screen. The higher the ratio, the better the picture display.
Average LCD TV has a contrast ratio ranging from 400:1 to 800:1. Plasma TVs ranging from 600:1 to the most sophisticated has the ability to 1.500:1.
The size aspect ratio describes the ratio of width to height screen. Conventional TV uses 4:3 format, while the large-screen TV use 16:9 ratio. This ratio does not vary much with the format used in cinema industry, which is very comfortable to watch DVD movies on the big screen, considering the comparison is not much different from 1.85:1 16:9.
In choosing a TV should be considered also aspects of the resolution. Plasma and LCD TV products already use the technology for fixed-pixel arrays. This means that this product already has rows and columns are fixed for a specific image format. In general, a good quality TV that is classified as high definition, if a resolution value of more than one million, ie starting from 1280 x 720, 1366 x 768 and 1024 x 1024.
Resolution for conventional TV's most high 852 x 480 so-called enhanced definition. Standards for TV tubes is generally located at a resolution of 640 × 480 and 720 × 480.
The difference is what makes these two technologies memunyai respective markets, as needed. Moreover, in terms of pricing is also much different.
