There are currently several television models. In the market are still the traditional ones, in tube, however, those that are in high, are the televisions of plasma, LCD or LED. In the year of 2002 appeared the plasma TVs in the Brazilian market, the great sensation. It was possible to see sharper, brighter and more colorful images than the space it occupied, much less than the traditional tube.
Shortly after the plasma TV came the LCD (liquid crystal display). Apparently, the image of the two models has no difference, however the difference is in the technology used. The big difference of the plasma TV and the LCD is the thickness of the screen, the LCD is thinner than the previous one. For most people the screen thickness was already good on the LCD TV, however, the LED TVs got thinner still. The thickness of the screen is only the thickness of a finger.
The process of forming the image of the LED TV is the same as the LCD TVs, however, the difference in the great reduction of thickness is in the type of light emission behind the screen, so-called, backlight. LCD TVs have fluorescent threads behind the liquid crystal, while the LED TVs have small LEDs at the edges of the screen, thus generating even higher picture quality than LCD TVs. The explanation for this is that the lamp used allows the process called “dimmer”, which dims the light in darker images, and thus improving the contrast of the TV. Another advantage compared to LCD TVs is power consumption. LED technology significantly reduces energy expenditure.
Normally on LED TVs there are the following items: Full HD (high definition images), bluetooth (wireless data transmission), HDMI inputs, PC audio input, DivX HD USB input, headphone jack, Wireless input Control, RGB input, Time Machine Ready, among others. With so many functionalities, then, what should we observe when buying an LED TV? First you need to choose the best TV size for your environment. Choose a suitable one that is not hidden or exaggerated. Your taste has a lot to do with this.
So when choosing the TV, you need to watch the TV brand. There are brands seen as more reliable and less reliable. Be sure to observe the mark that has technical assistance for a longer time. Choose a TV that has more HDMI inputs, it will make it easier for you to use one day. Be sure to know the contrast ratio, the more contrast, the better the image. For those who do not give up watching a good movie, make sure the desired television can be seen in 3D.
There are other options for those who want a complete handset, such as: Games, On / Off Timer, PIP, Clock, Skype, Wireless, among others. So, at the time of purchase, it is worth a good research on the product. The LED TVs, it seems, have come to stay. So if you want an appliance to be used for a long time and be able to enjoy several features, it is worth investing a little more. There are TVs in the market that range from $ 1,400 to over 10,000. For this, a good search in stores, internet forums and people who have the product is an excellent alternative to be sure which product to choose.
