OLED (Organic Light Emiting Diode) technology is truly amazing and many manufacturers speak for a while about the ability to launch large diagonal HDTVs that LED flood lightuse it. It is one of the reasons why there was so much interest when LG launched its new 55 inch OLED TV at CES 2012. It is gorgeous, both exterior and interior.
You will not find it in the nearest store at the moment I am writing this article (March 2012), but very soon you will and then you would better know the difference between OLED and LED TV on the market today. However, don't get me wrong, LED's are amazing too.
First, what is the difference? The main difference is that OLED TVs do not need a light source (backlight). They produce their own light, with the help of electrical current passing through the organic diodes. On LED TVs, the diode light created passes through a liquid crystal display. So although it eliminates the traditional light source, there are several layers that increase the thickness.
What happens when you compare an OLED TV with a normal LED TV?
Thickness
LG 55 inches OLED HDTV is not only the largest OLED TV at the moment, but is also the thinnest and lightest TV. Although he is 55 inches, it weighs only 7.5 kg and profile measuring is less than 4mm. Instead, even the largest thin LED TV does not measure less than 30 mm.
Contrast and black level
Adjustable LED TVs use technology to create dark areas. This means that black levels are dark but they can never be truly black. OLED screen may close areas needed depending on the scene. Besides, OLED TVs boast infinite contrast ratio, showing even the smallest details with the greatest accuracy and clarity. Together gives you the best experience. Because this we cannot compare the contrast in those two technologies.
Color Accuracy
Again, because OLED technology emits its own light, OLED TVs can create virtually any color in the spectrum. Not as is the case LED TVs which have to pass light through a matrix color LCD to produce the color. The process of creating color for OLED TV's is much easier and more accurate, resulting in a much richer experience. LEDs do a good job but OLEDs are always on top.
Viewing angle
Nothing can competes with OLED technology when it comes to viewing angles. Viewed from any angle and any position played OLED colors remain the same. LED technology represented a significant advance compared to normal LCDs, but you cannot compare with OLED technology.
Truly Green
LED TVs are quite energy efficient. Based on low power consumption, the packaging is easier, technology is more environmentally friendly than CCFL or LCD. But it cannot do what OLED technology can make. Because it does not need a light source, OLED technology uses significantly less energy during operation and standby. In addition, due to low weight and small size, the packaging is lighter and transportation costs are lower.
