Samsung UN40D6420UFXZA 3D HDTV LED Television, A Clear Winner

Samsung has been a force in the commercialization of flat screen HDTV sets; it is one of the top brands available. Their most recent sets are equipped with Light Emitting Diode back-lighting technology, instead of the cold-cathode fluorescent tube methods that were featured in the first LCD TV sets. The use of this LED technology has made it possible for them to produce sets that are thinner, and more lightweight than previous sets, but still produce substantially higher picture quality. The UN40D6420UFXZA Samsung 3D LED HDTV is a good example of this technological excellence.

Since an LCD (Liquid Crystal Display) doesn't produce any light, but instead acts as a shutter that varies the visibility of light as it passes through the display, any LCD display requires a back-light to be visible under dim lighting conditions. The LCD part of the display simply acts as a "shutter" that either allows light to pass through the display panel, or blocks it.

The first generation of LCD TV sets had the back-lighting provided by a set of miniature fluorescent tubes, which provide a white light. Each picture element, or pixel making up a TV picture is a location on the display that has 3 tiny filters that will create each of the primary TV colors: red, green, and blue (RGB). Each color TV image is then created by controlling the level of transparency of the LCD spot that controls the light that passes through each individual filter in each pixels that make up the entire image.

The UN40D6420UFXZA Samsung 3D LED HDTV set uses an edge lighting system to supply the back-light for its picture. In this system, very bright white-light LEDs (Light Emitting Diodes) are set around the edge of the screen . A diffuser plate then distributes this light across the full face of the picture. This use of an LED lighting system results in the TV requiring a lot less electricity to operate. This set is quite efficient: assuming an operating rate of 5 hours each day, and an electricity rate of $0.11 per Kwh, it would cost about $14/year to run this set. When the set is turned off, it uses only 0.07 Watts of electricity. That adds up to 0.6 Kwh/yr, which would cost less than $0.07, assuming the same electric rates!

This UN40D6420UFXZA Samsung set is loaded with what Samsung calls "Smart Apps" - the applications that form the basis of their "Smart TV" platform. These "Apps" allow you to use the TV to interact with the internet, and download content from the Web from sources like Pandora, Hulu, Netflix, and many others.

Another feature of this set is its use of "Allshare DLNA Technology". DLNA stands for "Digital Living Network Alliance". It is an interoperability protocol that enables a variety of electronic devices to link together to enable file sharing and data communication. Samsung's "Allshare" makes it a cinch to link your DLNA-enabled devices with your Samsung TV set, which means that you can use all the various media files that are on your computer, iPhone, and other devices on your HDTV set as well. Add to that the optional LinkStick, and you will be able to have wireless access as well.

This UN40D6420UFXZA Samsung TV also has the ConnectShare Movie feature. This makes it possible to look at pictures, watch videos, or play music 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 able to access the files.

The quality of the images you will see on the UN40D6420UFXZA Samsung is improved by the Ultra Clear Panel which makes up the front panel of the screen. This panel absorbs incident light that strikes it, which almost totally does away with the annoying reflections that would otherwise appear on the front of thescreen. This in turn provides a picture that has deeper blacks and improved contrast, giving you a cleaner, crisper image with wonderful shadow detail.

Owning this set will significantly your TV watching experience, as well as making it easy to interface with all your other media sources, including your computer, your other personal devices, and the Internet.
