Samsung has long been a leader in the commercialization of flat display HDTV sets; it is one of the most desired brands available. Their most recent sets include Light Emitting Diode back-lighting technology, which replaces the fluorescent systems that were used as a part of the first generation of LCD TV sets. The use of this LED back-lighting technique has made it possible for them to manufacture sets that are thinner, and lighter than previous sets, but still produce significantly higher picture quality. The UN40D6420UFXZA Samsung LED 3D HDTV is an excellent example of this technical excellence.
As a result of the fact that an LCD (Liquid Crystal Display) can not produce any light, but instead functions like a shutter that varies the passage of light through the display, all LCD displays require a back-light to be seen in dim lighting conditions. The LCD aspect of the display simply provides as a “shutter” that either permits light to pass through the display panel, or blocks it.
The first LCD TV sets had the back-lighting provided by a series of cold-cathode fluorescent lights, which emit a white light. Each picture element, or “pixel making up a TV picture is spot on the display that has 3 tiny filters that create each of the primary TV colors: red, green, and blue (RGB). Each color TV frame is created by controlling the level oftransparency of the LCD spot that controls the light that passes through each individual filter in each pixels that constitute the complete picture.
The Samsung UN40D6420UFXZA LED 3D HDTV set is equipped with an “edge lighting” system to provide the back-light for the LCD display. In this method of back-lighting, very bright white-light LEDs (Light Emitting Diodes) are placed around the edge of the screen frame. A diffuser plate distributes that light across the entire face of the display. The employment of the LED lighting frame means that the TV requires a lot less energy to operate. This Samsung set is quite efficient: assuming a usage rate of 5 hours each day, and an electricity rate of $0.11 per Kwh, it would cost about $14/year to operate this set. When the set is not running, it uses just 0.07 Watts of power. That adds up to 0.6 Kwh/yr, which is less than $0.07, assuming the same power rates – no “electricity vampire” here!
The Samsung UN40D6420UFXZA set is packed with what Samsung calls “Smart Apps” – applications that make up the foundation of their “Smart TV” platform. These “Apps” permit you to employ your TV to interact with the internet, and to download Web content from providers like Netflix, Hulu Plus, Pandora, and others.
Another aspect of this set is its “Allshare DLNA Technology”. DLNA refers to the “Digital Living Network Alliance”. It represents an “interoperability protocol” that enables different electronic devices to be linked together to enable file sharing and data communication. Samsung’s “Allshare” feature makes it a cinch to link most of your DLNA-enabled components with your Samsung TV set, which means that you can use all the media files that are on your computer, and iPhone, and other components on your HDTV set. Add to that the optional LinkStick, and you can have wireless access as well.
The Samsung UN40D6420UFXZA set also has something called 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 do is to insert the drive into the USB port on the TV set, and you are able to access the files.
The quality of the picture you see on the Samsung UN40D6420UFXZA is improved by the Ultra Clear Panel which makes up the front of the screen. This panel absorbs ambient light from the surroundings, which in turn almost totally eliminates those bothersome reflections that would likely appear on the front of thescreen. This in turn provides a picture that has darker blacks and enhanced contrast, resulting in a cleaner, crisper picture with great shadow detail.
Owning this TV set will significantly improve your TV viewing experience, as well as making it easy to interface with all your other media sources, including your your computer and other personal devices, and the Internet.
