The Samsung Company has been a leader in the development of HDTV flat panel sets; it is one of the premier brands on the market. Their latest sets feature LED back-lighting technology, which replaces the linear fluorescent tube systems that were used by the first generation of LCD TV sets. The use of LED technology has made it possible for them to design sets that are thinner, and weigh less than previous sets, yet produce substantially better picture quality. The Samsung UN46D6420U LED 3D HDTV is a perfect example of this technical superiority.
The 3D capability is one of the outstanding features of this set. Samsung uses the Active 3D method for displaying 3D images on their LED HDTV sets. The secret to creating the 3D effect is to be certain that each of the stereoscopic 3D images is visible only to the correct eye. This is done by one of two different methods, known as “passive” and “active”. Passive systems employ glasses that have polarized lenses that work in tandem with polarizing filters that are part of the TV screen.
These filters polarize two sets of alternating horizontal lines on the screen in one of two different patterns. Each eye then sees only the set of lines displayed on the screen (and therefore sees an image that has only half the full-screen resolution!) that matches the polarization of the lens on the right or left side in the glasses, insuring that each eye sees only one image.
With an Active system, the glasses “actively” alternate between being transparent, then opaque, by activating the LCDs in the lenses. Each eye is blocked sequentially, as the stereo image for the right or left eye is displayed on the screen. The synchronization is accomplished using a bluetooth signal provided by the TV set. These alternating images are shown at the rate of 120 HZ, so that each eye will see 60 images per second. Because each eye sees a full-screen image, there is no reduction of resolution in the 3D picture.
As mentioned earlier, Samsung’s 3D LED Tvs employ an Active 3D system. There are two types of glassed that can be used with these sets. The first type needs batteries, the other type uses rechargeable batteries, which can be charged using any USB connection. The rechargeable glasses are very lightweight, weighing only one ounce, and will work for tens of hours with just one charge.
The Active 3D system in the UN46D6420U also makes it possible to “up-convert” regular 2D content and programming to “near 3D” appearance. This means that the 2D program, whether network broadcasts, DVDs, or home movies can be given an appearance of depth that was not otherwise present in the original material.
The size of the TV screen is an important consideration when evaluating a 3D television purchase. The best seating distance, to avoid eye strain, is three times the vertical size of the TV screen. Based on that, for a 46″ screen (which has a vertical dimension of about 23″), the minimum suggested viewing distance should be approximately 67″, or approximately 5.5 feet. For a 55″ screen, the minimum suggested distance would be just slightly under seven feet. So, for this Samsung 46 LED HDTV model, the optimum viewing distance is about six feet from the screen.
The Active 3D system in this Samsung UN46D6420U LED TV is just the tip of the iceberg when listing its great technical features. This UN46D6420U Samsung set is packed with what Samsung calls “Smart Apps” – applications that form what they refer to as their “Smart TV” platform. These “Apps” allow you to use the TV to work on the Internet, and to download Web content from sites like Netflix, Hulu Plus, Pandora, and many others.
Although certain “Apps” must be purchased for a dollar or two (much like iPhone apps), there is a generous list of Apps that are free, such as children’s material and games. Apps categories include areas like Sports, Lifestyle, Videos, Games, Education, and Information.
Another great feature of this UN46D6420U TV is “Allshare DLNA Technology”. DLNA is an abbreviation for “Digital Living Network Alliance”. It represents a technical standard that makes it possible for a variety of electronic appliances to link to each other, in order to make possible file sharing and data transmission. Samsung’s “Allshare” makes it simple to synch up various DLNA-enabled devices with your Samsung TV set, which means that you can enjoy all the media files on your computer, iPhone, and other devices on your new HDTV set . Add the available LinkStick from Samsung, and you will have wireless access too.
The list of great features above is just the starting point for understanding what this set has to offer. Take a look at the specifications for the UN46D6420U, and you’ll begin to appreciate just what a great piece of technology it is.
