What is LED TV Technology

Find the answer to the frequently asked LED Lights related question: What is LED TV Technology?
So everyone, from the media to your tech-savvy friends, tells you that you need to upgrade your prehistoric television to an LED TV. What exactly is the difference, though? What is this LED TV technology that everyone is so keen on?

LED vs. LCD. vs. Plasma

Actually, an LED is just a specific type of LCD television. LCD stands for Liquid Crystal Display. LCD is one of the two major high-resolution formats for flat-screen TV sets. The other one is the plasma TV. An LCD television works by providing electric volts to liquid-crystal filled areas on the screen sandwiched in between a pair of identical sheets of glass. When these areas are hit with the voltage, the crystals start untwisting a bit, allowing white light to filter through (this is the light that comes from the lamp which sits behind the screen). The range and intensity of the backlight produces the range of colors that is desired.

Advantage of the LED Backlight

Even among all of the LCD high-definition televisions, there are variations- specifically in how the screen is lit. One of the preferred methods is through LED technology. LED simply means Light Emitting Diode. The LED TV is a new and still-developing phenomenon in lighting technology. As it relates to television technology, the main differences between fluorescent and LED lighting are the fact that the back lights in a fluorescent television must always stay on and the fluorescent TV does not offer the range of colors offered by the LED television.

What this means in practical terms is that a fluorescent backlight is incapable of producing true, deep blacks, because a small amount of the light always leaks through the screen's cells. The image, therefore, appears to be not very sharp. LED televisions eliminate this problem because the backlights don't always need to be on. Therefore, the LED TV provides a locally dimmed panel of LED lights that helps to make the image sharp in all areas.

Edge-Lit vs. Backlit LED TVs

Currently, there are two primary LED technologies available for the high-definition television. One is the edge-lit LED. On these, there is an array of lights around the display's perimeter. The benefit of the edge-lit TV is that it allows the set to be ultra-slim. Then there's the backlit LED TV. This television screen functions by placing a grid of LED lights behind the screen. This light grid can be controlled locally in order to produce rich color contrasts and deep blacks. Even if a scene requires complete blackness, then the LEDS in that spot can be totally shut off, so that zero light penetrates through the screen cells.

The Switch to LED TV

So is an LED TV worth it? Yes. It's true that it costs a bit more than fluorescent and plasma televisions. However, everyone who makes the switch has said that they appreciate the richer TV viewing experience it offers. You'll most likely consider it a worthwhile investment in your family's entertainment.
