UN40D6420UFXZA 3D LED HDTV TV from Samsung, A Definite Winner
Samsung is a force in the improvement of flat panel HDTV sets; it is one of the most desired brands on the market. Their latest sets feature Light Emitting Diode back-lighting technology, instead of the fluorescent methods that were featured by the first generation of LCD TVs. The use of this LED back-lighting technology has enabled them to manufacture sets that are much thinner, and more lightweight than earlier sets, yet produce significantly better pictures . The Samsung UN40D6420UFXZA LED HDTV with 3D is an excellent example of this technological excellence.
As a result of the fact that an LCD (Liquid Crystal Display) doesn’t produce any light, but instead acts as a shutter that adjusts the passage of light through the screen, all LCD displays require a back-light in order to be visible under dim lighting conditions. The LCD part of the screen simply acts as a “shutter” that will allow light to pass through the display panel, or prevents it from doing so.
The first LCD TV sets were back-lighted by a set of miniature fluorescent tubes, which produce a white light. Every picture element, or “pixel making up a TV picture is spot on the screen with 3 filters that produce the primary TV colors: red, green, and blue (RGB). Each color TV picture is then created by controlling the level oftransparency of the LCD element that controls the light that passes through each of the filters in each of the pixels that make up the complete image.
The UN40D6420UFXZA Samsung LED HDTV with 3D set is equipped with an “edge lighting” system to supply back-lighting for the LCD display. In this method, very high intensity white-light LEDs (Light Emitting Diodes) are set around the edge of the screen . A diffuser plate then spreads this light through the full surface of the picture. This use of the LED lighting frame results in the TV requiring much less energy to operate. This set is quite efficient: assuming a usage rate of five hours each day, and an electricity rate of $0.11 per Kwh, it would cost around $14/year to run this set. When the set is off, it consumes only 0.07 Watts of electricity. That amounts to 0.6 Kwh/yr, which is less than $0.07, assuming the same electric rates – no “electricity vampire” here!
This UN40D6420UFXZA Samsung set is packed with what Samsung calls “Smart Apps” – theapplications that make up the foundation of their “Smart TV” platform. These “Apps” allow you to use the TV to interact with the internet, and download Web content from sources like Netflix, Hulu Plus, Pandora, and many others.
An additional feature of this set is its “Allshare DLNA Technology”. DLNA stands for “Digital Living Network Alliance”. It is an “interoperability protocol” that enables different electronic devices to link together to enable them to share files and data communication. Samsung’s “Allshare” feature makes it easy to link most of 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, and iPhone, and other devices on your HDTV set as well. Add in the optional LinkStick, and you can have wireless access in addition.
This UN40D6420UFXZA Samsung set also includes 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 set, and you are ready to go.
The sharpness of the picture you see on the UN40D6420UFXZA Samsung is increased by the Ultra Clear Panel which forms the front panel of the screen. This panel absorbs ambient light from the surroundings, which in turn almost totally does away with those annoying reflections that could otherwise be present on the screen. This in turn gives you a picture with darker black areas and better contrast, giving you a cleaner, crisper picture with wonderful shadow detail.
Getting this set will substantially improve your TV viewing experience, as well as making it easy to connect with all your other media files, including your computer, your other personal devices, and the Internet.
