Among Manufacturers of flat panel HDTV sets, Samsung is the Industry leader. It has had the best sales position among manufacturers of flat screen TVs for many years. For the first quarter of 2011, Samsung sold 30% more flat panel TV sets than its closest rival. If you have seen a Samsung HDTV set you will certainly not be surprised by that.
The images you will see on a Samsung HDTV are stunning in their sharpness and brilliance. Combine that with the high level of technical design and the broad range of features that Samsung includes in its sets, and you have a very strong argument for anyone thinking about purchasing of one of these sets....and that's without even considering the Active 3D capabilities of these sets!
Samsung has adopted what is termed "Active 3D" for their line of HDTV sets. This is one of two approaches to creating 3D television images that are currently in use. The other approach to the 3D problem is termed "Passive 3D". There is a significant difference between the two, and it shows up in the perceived quality of the images that are displayed.
Creating a 3D image requires that your left eye and your right eye must see an image which is slightly different, ones in which objects which are at various distances from you appear in a different place. To observe this effect, hold up one finger at arm's length, and observe it with only your right eye, and then with just your left eye. As you do this, notice the position of the object when compared to other objects that are at a greater distance.
You will note that when using your right eye, your finger is to the left of certain objects, but when using your left eye, the apparent location of your finger will appear to move to the right, relative to the same object. This effect is called "parallax", and it is the basis of the method used to produce the 3D effect on a television or movie screen.
The key distinction between the different systems, the Active system and the Passive system, is in the method used to present the different stereoscopic images to the appropriate eye. A three-dimensional perception will only be seen if each eye can see only the proper image. As you may have already observed, if you look at a 3D image without 3D glasses, you will see a double image. In order to observe the 3D effect, your brain must receive a different image from each eye, and those images must the proper parallax.
Passive systems employ glasses with polarized lenses that work in tandem with polarizing filters that are built in to the TV screen. These filters polarize two sets of alternating horizontal lines on the screen in one of two different polarization patterns. Each eye then sees only one of the two sets of lines on the screen (and therefore sees an image that has only half the full-screen resolution!) that match the polarization of the lens left or right in the glasses that matches the screen polarization for those lines.
With an Active system, the image for each eye is presented on the screen alternately, first for the right eye, and then for the left eye. These alternating frames appear at a rate of at least 120 frames per second. Obviously, if these alternating images were observed without some kind of filtration to insure that the proper image was seen only by the correct eye, the result would again be a double image. To make sure that each eye sees only the correct image, an Active system employs glasses with LCD filters. These filters can be made clear, or opaque, by switching the LCD filters on, or off. These glasses use a Bluetooth signal from the TV set to coordinate the switching of the lens filters with the display of the images on the screen. Because the image for each eye uses all the lines on the screen, there is no loss of resolution in the image - each eye sees the full 1080 line image, just half the time.
The Samsung UN40D6400, like all Samsung 3D HDTV sets, uses the Active system. In addition to great 3D TV, this set has a wide array of other great features that will make it your complete media center. It's screen uses LED edge lighting to provide the illumination for the picture (since LCD's do not produce any light). This system replaces the fluorescent tubes (yes, really!) that were used in previous generations of LCD flat screen TV sets.
Samsung has something on their HDTVs that they call "Smart Apps" - these are small programs that run on the TV. These "Apps" are similar to iPhone Apps, they are programs that actually run on the TV set itself. (It's clear that these TVs have a very large amount of processing power built into them.) While some of these Apps must be paid for, their cost is very much "pocket change", there are also quite a few Apps that are available totally free of charge. These Apps range over a long list of subject areas that include Education, Games, Videos, Sports, Lifestyle, and Information. There are some Apps that you can use to browse the Internet, and let you make use of services like Netflix, Pandora, Hulu Plus, and many others.
The Samsung UN40D6400 set has an interesting and useful feature called the "ConnectShare" Movie feature. This enables you to run videos, listen to music, or browse pictures from a USB Thumb Drive. Just insert the drive in the USB port on the TV, and you are ready to enjoy all of your media files.
Along with all the electronic features, Samsung has also designed this set to minimize the effects of the room environment on the TV screen. The set features their "Ultra Clear Panel" on the front of their screens. This panel has a specially treated surface that absorbs light from the room. This greatly reduces those distracting reflections that would otherwise be seen on the screen when there are windows or other lights in a bad position relative to the TV set, and which would interfere with your enjoyment of those crystal clear pictures.
