When you are ranking the Manufacturers of flat panel LED HDTV sets, Samsung is clearly the Industry leader. It has had the highest sales volume of all the manufacturers of flat screen TVs for quite a few years. For the first quarter of 2011, Samsung’s lat panel TV set sales were 30% more than its closest competitor. If you ever had the chance to see a Samsung HDTV in operation set you will not find that at all surprising.

[I:http://autorepairarticles.com/autorepairarticles/wp-content/uploads/2012/01/CarltonTDriver15.jpg] 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’s 3D sets employ an “Active” 3D approach. This employs glasses with LCD lenses which serve like shutters. These lenses alternately lighten and darken for one eye or the other as the picture frame for the particular eye is being shown on the screen.. The other way of approaching the 3D problem is called “Passive 3D”. There is a very big difference between the two methods, and it becomes apparent in the perceived quality of the images that are you see on the sets.

The ability to create an image on a screen that has the appearance of depth – what is commonly called 3D – relies on the stereoscopic visual effect that results from viewing a different image with each eye. To understand how this works, try this simple experiment. Hold up an object (or just your finger) at arm’s length, and observe it with just the right eye, and then with only your left eye. As you do this, take note of the apparent position of that object when compared to objects that are further away.

You will notice that when looking through your right eye, the object will appear to be to the left of certain objects in the background, but when looking through your left eye, the apparent position of the object will seem to have shifted to the right, relative to that same background object. This illusion is referred to as “parallax”, and it is the basic principle of the two systems used to create the 3D effect on a television or movie screen.

The key difference between the two systems, the Active system and the Passive system, is in the way the two stereoscopic images are presented to the appropriate eyes. A three-dimensional effect will only occur if each eye sees only the correct image. (Think back to your old View-Master). As you may have experienced, if you look at a 3D movie or TV image without the proper glasses, all you see is a double image. The 3D effect requires that your brain sees a distinctly different image from each eye, and that the images have the proper parallax.

The Passive system for creating 3D images uses glasses with polarizing filters that are set at 90 degrees relative to each other. The image on the screen is also passed through polarizing filters, with alternating scan lines being polarized in the two different directions. This means that for an HDTV picture, with 1080 horizontal lines per frame, that 540 lines are polarized in one direction to create the image seen by the right eye, and the other 540 alternating lines are polarized in the 90 degree direction, for the left eye. The result of this is that you see an image which has an effective resolution of 540 lines, just half of what is required for true HDTV, which is 1080 lines.

With the Active 3D system, the lenses in the glasses “actively” become alternately opaque, then transparent, through control of the LCDs that are used in the lenses. Each eye is blocked in sequence, as the image frame for the right or left eye is being shown. The coordination of the images with the glasses is achieved by synchronizing the 3D glasses with a signal that is transmitted by the TV set. The different frames are displayed at the rate of at least 120 HZ, that means that each eye will see at least 60 images per second. Since each eye sees the full-screen, 1080i HDTV image, there is no loss of resolution in the screen image.

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 a wide range something they call “Smart Apps” – small “applications” that run on their TVs. These Apps are small programs (similar to iPhone Apps) that actually run on the TV set. (It’s worth noting that these TVs have a large amount of processing power at their disposal.) Although some of these Apps must be purchased, the cost is pretty much pocket change, and there are quite a few free Apps. These Apps cover a very broad range of subject areas including Videos, Sports, Lifestyle, Education, Games, and Information. There are also some Apps that will allow you to browse the Internet, and to make use of services like Netflix, Pandora, Hulu Plus, and many others.

The Samsung UN40D6400 set also has a feature called “ConnectShare” Movie feature. This will allow you to view videos, listen to music, and browse pictures straight from a USB flash drive. You simply plug the drive into the set’s USB port, and you are ready to watch or listen to all of your entertainment media files.

In addition to all the great electronic features, Samsung has designed this set to improve your viewing experience by minimizing reflections from the room environment on the TV screen. The set features Samsung’s “Ultra Clear Panel” at the front of their screens. This special panel has a treated surface that will absorb light from around the room. This helps to eliminate those distracting reflections that would otherwise interfere with the TV picture.

Samsung has long been a force in the improvement of HDTV flat panel sets; it is one of the leading brands on the market. Their newest sets employ LED back-lighting technology, which eliminates the cold-cathode fluorescent lighting systems that were included in the first generation of LCD TV sets. The use of this LED technique has made it possible for them to produce sets that are thinner, and lighter than earlier sets, yet they produce significantly higher picture quality. The Samsung UN46D6420U LED 3D HDTV is a good example of this technical superiority.

[I:http://autorepairarticles.com/autorepairarticles/wp-content/uploads/2012/01/CarltonTDriver13.jpg] One of the most impressive features of this set is its 3D display capability. Samsung has adopted what is termed the Active 3D method for creating the 3D pictures on their LED TV sets. The key to achieving the 3D effect is to insure that each left or right image is visible by the proper eye. This is achieved by one of two methods, which are termed “active” and “passive”. Passive systems employ glasses that have polarized lenses that work together with polarizing filters that are built into the TV screen.

These filters polarize alternating horizontal lines in one of two different polarization patterns. Each eye then can see 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 over the left or right eye in the glasses that corresponds to the screen polarization for those lines.

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 said previously, Samsung’s 3D sets use the Active 3D system. They have two types of glassed available. One set requires batteries, and the other type is rechargeable, using a USB connection. The rechargeable glasses are very light, weighing only one ounce, and last for many hours of use per charge.

Samsung’s Active 3D system also enables you to “up-convert” standard 2D content and programming to what is called “near 3D” appearance. This means that the 2D programming, whether network broadcasts, DVDs, or your own home movies can be displayed with the appearance of depth that isn’t otherwise present in the original material.

The dimensions of the screen and the size of the room are important factors to consider when choosing a 3D television set. The optimal seating distance, to avoid eye strain is 3x the vertical dimension of the screen. On that basis, for a 46″ screen (which is about 23 inches high), the closest distance should be about 67″, or approximately 5.5 feet. For a 55″ screen, the closest distance would be slightly less than seven feet.

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 some of the “Apps” must be purchased for a dollar or two (much like iPhone apps), there is a broad list of free Apps, such as children’s material and games. Apps categories cover areas such as Videos, Sports, Games, Lifestyle, Information, and Education.

Another really nice feature of this model UN46D6420U is its use of “Allshare DLNA Technology”. DLNA is an abbreviation for “Digital Living Network Alliance”. It represents what is called an “interoperability protocol” that enables different electronic devices to link together in order to make possible file sharing and data transmission between the devices. Samsung’s “Allshare” makes it simple to synch up various DLNA-enabled components with your Samsung TV set, which means that you can access all the various media files on your computer, iPhone, and other devices on your HDTV set . Add the optional LinkStick, and you will have wireless access too.

The use of this LED technique has made it possible for them to produce sets that are thinner, and lighter than earlier sets, yet they produce significantly higher picture quality. The Samsung UN46D6900W LED 3D HDTV is an excellent illustration of this technical superiority.

[I:http://autorepairarticles.com/autorepairarticles/wp-content/uploads/2012/01/CarltonTDriver12.jpg] Because an LCD (Liquid Crystal Display) doesn’t produce any light, but instead functions like a shutter that adjusts the visibility of light as it passes through the display, all LCD displays require a back-light in order to be seen under dim lighting conditions. The LCD element of the screen simply functions as a “shutter” that either permits light to transmit through the display screen, or prevents it.

It is like a very tiny venetian blind: if the crystals in a display cell are arranged perpendicular to the screen, light is able to pass through, and it will be bright. When the crystals are aligned parallel to the display, the passage of light is prevented, and the cell will appear black.

Consequently, while an LCD display can be seen in bright lighting conditions, to be seen in low intensity lighting situations – or to create a usable TV picture – there must be a light source behind the LCD display screen that provides the needed illumination, what is known as a back-lighting system.

The first models of LCD TV sets were back-lit by a series of cold-cathode fluorescent tubes, which produce a white light. Each picture element, or “pixel” that constitutes a TV picture is a position on the display screen with three microscopic filters that produce the primary TV colors: red, green, and blue (RGB).

The UN46D6900W Samsung LED HDTV with 3D set uses an “edge lighting” method to provide the back-lighting for its image. With this approach, extremely intense white-light LEDs (Light Emitting Diodes) are located around the edges of the screen frame. A diffuser plate is used to distribute the light across the full face of the display. The use of an LED lighting system results in much lower energy consumption.

The use of LED technology makes it possible for Samsung to have much better control over the brightness of each area of the image. They have created a system they refer to as “Micro Dimming”, which permits them to vary the intensity of the back-light from one area of the screen to another, which means that the picture has more brilliant whites, and that the black areas are much darker and deeper than was the case with the older LCD sets, which were lighted with fluorescent lights which stretch the entire width of the screen.

This set is highly energy efficient: based on a using the set for five hours every day, and an electricity rate of 11 cents per Kwh, it would cost about $15/year to operate this set. When the set is turned off, it uses only 0.07 Watts of power. That adds up to 0.6 Kwh/yr, which adds up to less than $0.07 per year based on the same electric rates – no “electricity vampire” here!

This Samsung UN46D6900W set is packed with what Samsung refers to as “Smart Apps” – applications that make up their “Smart TV” platform. These “Apps” allow you to use the TV to interface with the Internet, and to download Web content from sites like Hulu Plus, Netflix, Pandora, and others.
