Question Regarding LCD and plasma TVs
LCD TVs use the same technology with a laptop screen or flat screen monitor. 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 screens using the technology in the form of small glass balls that contains a gas called plasma. When energized electrical energy, the plasma gas is released 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 still many other differences of both technologies, such as size and flat-screen technology.
LCD TVs have limitations in terms of dimensions, because the LCD is actually designed as a computer monitor. Currently, the biggest screen is a Samsung 46-inch size. TV was launched mid-2004, having previously shown at the exhibition of electronics and household appliances in New York, April. Therefore, the size of LCD TVs are generally located in the market currently ranges between 15, 17, 20, to 22 inches.
Plasma TVs have a screen size 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 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 the power consumption of plasma TVs twice that of LCD TVs. The main cause is there? Cooling system is on 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 look of the TV picture, both have different characteristics. Plasma TV screens tend not to be able to display black properly. Even though compared to CRT TVs, 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. Her image remains even though TV broadcasts have moved to other impressions.
In the matter of the quality movement of the image, to have the benefits of plasma TV capable of displaying the image of fast-moving images. So the displacement image as an action movie (action) is more comfortable to watch on a plasma TV. Then from the point of view, plasma TVs have the advantage can be viewed from all angles, just like conventional TV.
Usually plasma TVs sold in the form of video displays, so it remains to be burdened with buying a TV tuner (tuner wave) and speakers.
By contrast 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 toward the screen. When viewed from the other side, who looked only a shadow only. The advantage is an LCD TV does not require excessive cooling system, so that his voice is more smooth than plasma TVs. So, it could be an option for those who need a screen for the computer and watching TV.
For those who intend to replace his TV with a large size, several other aspects to consider is contrast ratio, aspect ratio and resolution. Contrast plays an important role in generating an image that is comfortable to watch. The value refers to the dark or bright screen. The higher the ratio the better the picture display.
The average LCD TV has a contrast ratio ranging from 400:1 to 800:1. Plasma TVs ranging from 600:1 to the art has the ability to 1.500:1.
The size aspect ratio describes the ratio between the width of the screen height. Wearing conventional 4:3 TV format, while the large-screen TV use 16:9 ratio. This ratio is not much different from the format used by the movie theater industry, so it is very comfortable to watch DVD movies on widescreen, 1.85:1 per banding considering not much different from 16:9.
In choosing the TV aspect of the resolution should be considered as well. Plasma and LCD TV products already use the technology of fixed-pixel arrays. That is, this product already has rows and columns are fixed for a specific image format. In general, a good quality TV that is classified as a 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 of conventional TV for the highest 852 x 480 so-called enhanced definition. Standards for tube TVs generally are at a resolution of 640×480 and 720×480.
The difference is what makes these two technologies have respective markets, as needed. Especially in terms of price too much different.
