LED TV a Tweaked LCD?
All LED TVs contain an LCD display element (front panel). The difference of LED TVs lies in the backlight. Rather than the standard florescent backlighting systems of the past, LED TVs have LED bulbs (light emitting diode) as the backlight for the LCD panel. This has been a boost for LCD TV manufacturers as it has allowed them to better compete in picture quality against Plasma TV technology. Essentially a LED TV is an LCD TV with LED lights instead of the florescent bulbs.
In plasma displays, each pixel contains red, green, and blue elements, which work in conjunction to create billions of colors. Because each pixel contains all the elements needed to produce every color in the spectrum, color information was more accurately reproduced with plasma technology than it was with other display technologies. The chromaticity coordinates were more accurate on most plasma displays however lately LED TVs have closed this gap through manipulation of the new backlighting system.
Due to the 120/240 refresh rates of many new LED TVs, there is much improvement in reducing motion related blur. Plasma displays have always been excellent in this area. There is more background information coming forward. Foreground images really pop off the screen.
LED = More Green?
As the consumer market becomes more “Green Conscious”, so have the marketers of TVs. Though there are new energy saving technologies present on both LED and plasma TVs, most will not be used by the consumer due to the simple fact that they reduce the brightness of the picture.
