A bit about the origins of LED technology
Light-emitting diodes (LEDs) were an accidental discovery at first. At the beginning of the 20th century, it was discovered that when electricity was applied to the semiconductor Silicon Carbide (SiC) it produced a light. This light was too dim to be of any use so the research was never distributed. This could have been the end for the LED, but it wasn't content to die out.
Nearly 20 years later Russian and German scientists revisited the idea of light produced this way. The light was still of such poor luminance that the idea nearly died again. A report published in 1936, which helped to invent the term electroluminescence, revived the research for light from this source. The science of electroluminescence languished in obscurity for a while. It began to gain favor again in the 1950s when some British scientists started experimenting with it again. This led to the first infrared LED. From this technology came the first visible spectrum LED, in red, from Gallium Phosphide (GaP).
This was the start of the LED revolution. From that point each decade brought advances in the technology of light-emitting diodes. The use of different substrates brought brighter lights of different colors. The colors advanced from red to orange and on to pale green, then yellow and on to a brighter green. By the 1990s the use of Gallium Nitride helped usher in the era of blue LEDs. These blue lights became the basis for white light. The use of fluorescent phosphors helped change that blue light into high intensity white lights. Now LEDs can be found in almost every visible color of light.
This technology has led to additional uses for the LED as well. Due to their low light output they started out in indicator lights and display light applications only. The cost of materials was an issue at first and, therefore, they were used only in expensive laboratory and test equipment. They later began to be used in appliances, calculators and watches. The advent of additional colors increased their use in displays. They could be used in signs and digital display equipment.
The first LED flat panel television prototype was produced in 1977, by James P. Mitchell. This prototype was a red, monochromatic display. Later, in the 1990s, low-cost, efficient blue LEDs emerged moving this use along. Once a full spectrum of colors was realized in the late 1990s the flat panel LED television became a fully functional and popular option.
As the LED technology advanced and the luminescence increased, the uses for LEDs increased. LEDs began popping up in devices used to illuminate areas. Flashlights, landscape lighting, and other lighting sources became popular. Emergency lights began to use this technology. Traffic lights were replaced with LEDs. Interior lighting and headlights in vehicles became a common home for these lights, as well. As the cost of producing the lights decreased, and the availability of colors and brightness increased, the uses exploded.
From an accidental discovery to a common household name, the history of LEDs is a long one. The early discovery and limited uses of the light-emitting diode did not show much promise. Very few early researchers would probably have predicted the many, varied uses for this technology. The LED certainly earned its prominent spot in today's society.

Samsung 3D plasma vs Samsung 3D LED...?
I have a samsung 63 inch Plasma 3D television, and I am returning because of the brightness levels in 3D. Im switching for the 65 inch LED samsung 8000 series for better 3D brightness. Questions:
1) Is this a smart choice? Money is not an issue.
2) Does the LED version have more crosstalk? If so is it constant or only sometimes slightly noticeable?
Thanks in advance to those who can help me out!
Cnet has a round-up of five 3D tvs here, including the two series you mentioned (the models they reviewed had smaller screen sizes, but otherwise are identical in quality to the same models you referred to): http://reviews.cnet.com/2795-6482_7-419.html?tag=centerColumnArea1.2;buyAdvice .
The plasma TVs showed the least amount of crosstalk and were rated the best for 3D. The table below the article also has links to the more detailed reviews for each TV.
Keep in mind that sometimes crosstalk can be an issue with the video file on the Blu-ray, and can not be eliminated by even the best 3D TV. Reviews for 3D discs usually mention any presence of crosstalk for that disc.
Here are some excellent choices for
