LED TV - not to deceive the first technology figure

Thinking of buying a TV LED as well .... Stop! Before spending more than $ 1500, you must cut through the jargon and hype to really understand the technology spending your hard earned money. Manufacturers of TV and media are actually very good, convincing us that newer products integrate the latest technologies and are a must. Lets get real here for the average consumer, most of these jargon is just down right confusing.

A newRange of LED televisions, the market took a big sum. Samsung sneaking out the back door and release the 7000 series range has boasting of LED technology.

How nice ... but what the LED technology is thats boasts?

Current TV LED - The truth, the term "LED is Light Emitting Diode and LED are available as you may know that many of our products are compared to the current line of LED TVs, the actual lights used to be, but for theBacklight of the TV and not just the TV show itself. If one considers that the current TV technology) used CCFL (cold cathode fluorescent lamps, there is no doubt that an LED-backlit backlit is a more efficient form.

But the important point here is that the LED display is actually the LCD (Liquid Crystal Display), it's just the backlight, which consists of LEDs. So there are two important technologies to be used here, as the LCD and LED the backlight. Essentially an advanced form of LCD TVs.

If you compare this technology in a real TV LED. View as OLED (Organic Light Emitting Diode) is self-illuminated, using a thin internal LED for display only.

The fact that the 'TV LED the word was "used to describe a type of LCD TV is a clever move by Samsung, but genius in marketing, as they hum performance in the current> LED display TV market of the real TV like Sony XEL-1 OLED TV.

LCD TV with LED backlight - The improvements now that we found this LCD TV with LED backlight allows us, as this new series of TV technology improves current TV, LCD and plasma as standard in three main areas:

1. Image quality Very simply, the image quality was improved plasma and LCD standard, because theChoice of colors is increased. The use of LEDs as light source instead of conventional lamps offer a higher contrast ratio, because the LED produces deeper blacks and whiter whites, which is the key to a high-quality images on the screen.

2. Environmental LED technology consumes less power than the current TV backlight technology, which is a saving on electricity bills.

3. Slender models. Since no provision fortraditional source of light is needed, LED TVs are made to be ultra thin, this makes for a thin, smooth, the model more attractive.

Decisions, decisions that are in the market for television and now want a quality image in advance of the standard current LCD and plasma ranges on the market, then you can not do much wrong with a TV LED.

However, if you are in no hurray to present the art of buying a TV at this time and that require a TV with thatkeep in the forefront of cutting edge technology in terms of LED, OLED TV the real deal. Laser TV is another option to explore.

Both are new technologies require patience and how to find their place in the market with the right screen size for the home. This TV can also ask that you dig a little 'more in your account.

The moral of the story is the technology behind the product in great detail before figuring in part with your money,You have a choice.

Panel TV technology

The world of today, beating dozens of TV technology, the other to fight the trumpet. But it flows to the user, because it decides the fate of all things new on the market. TV-panel TV can be divided into two types, namely direct-view TV and Flat. Also known as CRT televisions, direct view televisions have been replaced by flat-screen TVs in most homes. Bulky and can release heat over repeated use, have a lot of CRT TVDisadvantages. The next category most attractive flat-screen TV. These are classified into two types, namely, plasma and LCD TV.

LCD stands for Liquid Crystal Display. There is a thin flat screen for display of electronic information, such as text, using moving images, etc. And 'one of the fastest growing technologies of video-display in the market today. Sales of liquid crystal devices took tube set some years ago. An LCD panel is composed of pixelstransparently between the two electrodes and two polarizing filters down. When light is passed between them, the filters get excited and crystal clear images can be displayed. The electrodes are made of indium tin oxide (ITO) has been prepared. At the request of an electric field the liquid crystal molecules are oriented in alignment of the electrodes. Their surface orientation perpendicular to each other and the molecules are arranged in a spiral-shaped structure. This method, which is used in LCD glassis polarizing. This improves response times, higher resolution and better contrast and brightness. LCD panels using four techniques, namely SSFLC (surface stabilized ferroelectric liquid crystal), FLC (ferroelectric liquid crystal display), DSTN (Dual Scan Twisted Nematics) and STN (Super Twisted Nematics).

The other type of flat-screen TV and plasma TV. This is a flat screen with a screen size of 32 inches begins. It is composed of small cells instead of twoGlass plates. The glass is a mixture of noble gases. When electric current is passed, the gas is turned into plasma cells, excited phosphors to emit light. Much thinner than CRT, the image quality varies depending on the type of video-scale. In its first days, plasma televisions more definition with a resolution of 840 x 180 pixels native. But the high-definition televisions, plasma 42 inches today usually have a resolution of 1024 x 768 pixels.

Both technologies mentioned above(LCD and plasma) have their share of advantages and disadvantages. The screen size of plasma TV 32 "LCD TV while the smallest 10" are available. Plasma TVs can tend to suffer from "burn-in of static images, while LCDs are free of them. Plasma TVs are not good at high altitudes and are heavy and bulky as compared to the LCD TV. However, plasma TVs better manage the movement of LCD TVs and LCD-shine when it comes to color saturation and detail. In fact, it isNot an easy task to choose between the two. But, as a user, you should always go for the atmosphere and needs of your ad is the best.
