UN40D6420UFXZA 3D HDTV LED TV from Samsung, A Clear Winner

Samsung is a force in the commercialization of flat display HDTV sets; it is one of the top brands available. Their latest sets are equipped with Light Emitting Diode back-lighting technology, which replaces the cold-cathode fluorescent designs that were used as a part of the first generation of LCD TV sets. The use of this LED technique has made it possible for them to produce sets that are much thinner, and more lightweight than earlier sets, but still produce substantially better picture quality. The UN40D6420UFXZA Samsung LED 3D HDTV is an excellent example of this technical excellence.



Since an LCD (Liquid Crystal Display) can not produce any light, but instead functions like a shutter that controls the passage of light through the display, all LCD displays require a back-light to be seen in dim lighting conditions. The LCD element of the display simply functions as a "shutter" that either allows light to pass through the display panel, or prevents it.

The first generation of LCD TV sets had the back-lighting provided by a set of cold-cathode fluorescent tubes, which provide a white light. Each "pixel" or "picture element" making up a TV picture is spot on the display that has three microscopic filters that create each of the primary TV colors: red, green, and blue (RGB). Each color TV image is then created by controlling the level oftransparency of the LCD spot that controls the light that passes through each individual filter in each of the pixels that make up the entire picture.

The UN40D6420UFXZA Samsung LED 3D HDTV set has an "edge lighting" system to supply the back-light for its picture. In this method, bright white-light LEDs (Light Emitting Diodes) are placed around the edges of the screen . A diffuser plate then disperses this light through the entire face of the picture. The use of the LED lighting frame results in the TV requiring much less energy to operate. This Samsung set is extremely efficient: assuming an operating rate of 5 hours each day, and a cost of electricity of $0.11 per Kwh, it would cost about $14/year to operate it. When the set is not running, it uses just 0.07 Watts of electricity. That adds up to 0.6 Kwh/yr, which would cost less than $0.07, assuming the same power rates!

The UN40D6420UFXZA Samsung set is loaded with what Samsung refers to as "Smart Apps" - theapplications that make up the basis of their "Smart TV" platform. These "Apps" permit you to employ your TV to interface with the internet, and to download Web content from sources like Hulu Plus, Netflix, Pandora, and many others.

An additional aspect of this set is its "Allshare DLNA Technology". DLNA stands for "Digital Living Network Alliance". It is an "interoperability protocol" that enables a variety of electronic devices to be linked together to enable them to share files and data transmission. Samsung's "Allshare" feature makes it simple to link your DLNA-enabled devices with this Samsung TV set, which allows you to use all the media files on your computer, and your iPhone, and other devices on your HDTV set as well. Add in the optional LinkStick, and you will be able to have wireless access as well.

The UN40D6420UFXZA Samsung TV also has the ConnectShare Movie feature. This gives you the ability to play music, watch videos, or look at pictures from any USB flash drive. All you need to do is to plug the drive into the USB port on the set, and you are ready to go.

The quality of the images you see on the UN40D6420UFXZA Samsung is increased by the Ultra Clear Panel which forms the front of the screen. This panel absorbs ambient light from the surroundings, which in turn almost totally does away with those annoying reflections that would otherwise be present on the front of thescreen. This then provides a picture that has deeper black areas and better contrast, giving you a cleaner, crisper picture with wonderful shadow detail.

Owning this set will significantly enhance your television watching experience, and will make it easy to connect with all of your other media files, for example your your computer and other personal devices, and the Internet.
