Samsung 40d6400 Led 3d Hdtv Set If you are looking for a flat panel HDTV set, you will certainly want to consider Samsung, almost certainly the Industry leader.
It has been the top selling manufacturer of flat screen TVs for many years. As of early 2011, Samsung had sold 30% more flat panel TVs than its closest rival. Anyone who has seen a Samsung HDTV set in operation will not be terribly surprised pandora charms official site at that fact. The clarity and sharpness of the pictures their sets produce are stunning. This is one of the approaches used to create 3D television images in the sets that are currently on the market. The other way to solve to the 3D problem is termed "Passive 3D". There is a very important difference between the two, and it shows up in the observed quality of the images that are displayed. The process required to create a image on a screen that has a sense of depth what is commonly called 3D relies on the stereoscopic principle, a visual effect that results from viewing a different image with each eye. To see an example of how this works, try this quick experiment. Hold up an object (or just your finger) at full arm's length, and look at it with just your right pandora necklace australia eye, and then with just your left eye. Alternate the eye you look through, back and forth. As you do this, take note of the apparent position of the object when you compare it to objects that are further away from you. You will note that when seeing through your right eye, the object will seem to be positioned to the left of certain objects in the background, but when you are sighting through your left eye, the relative position of the object will be seen to have shifted right, relative pandora charms katalog to that background object. This visual illusion is referred to as "parallax", and it is the fundamental principle of the two systems that are used to produce 3D effects on a television or movie screen. The important difference between the two systems, Active and Passive, is how the two stereoscopic images are delivered to the correct eyes. The three dimensional effect will only be seen if each eye sees the correct image, and only the correct image. (Think back to your old View Master). As you may have seen, if you look at a 3D movie or TV image without the 3D glasses, you see a double image. To achieve the 3D effect, it is essential that your brain sees a distinctly different image from each eye, and that the images that are seen have the proper parallax. The Passive system for displaying 3D images employs glasses that have polarizing filters set at 90 degrees relative to each other. The picture on the screen also passes through polarizing filters, with alternate scan lines being polarized in the two directions corresponding to the lenses in the glasses. For an HDTV picture with 1080 horizontal lines per frame, consequently, 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 degrees opposed direction, for the left eye. The result of this is that what you see is 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 system, the image for each eye is displayed alternately, first for the right eye, and then for the left eye. These alternating frames appear on the screen at a rate of at least 120 frames per second. Clearly, if these alternating images were observed without the proper filtration to insure that the proper image was seen only by the appropriate eye, the result certainly be a double image. To make certain that each eye can only see the correct image, the Active system employs glasses using LCD filters. These filters can changed from clear, to opaque, by switching the LCD filters on, or off. The glasses use a Bluetooth signal sent by the TV set to coordinate the switching of the lens filters with the display of the images on the screen. Since the image for each eye uses all of the 1080 lines on the screen, there is no sacrifice of resolution each eye can see the full 1080 line image, just half the time. The Samsung UN40D6400, like all Samsung 3D HDTV sets, utilizes the Active 3D approach. In addition to great 3D TV, this set has a broad range of other elegant features that will make it your complete media center. It uses LED edge lighting to provide the illumination for the picture (since LCD's do not produce any light). This system replaces the fluorescent pandora charms blog tubes (yes, really!) that were used in the previous generation of LCD flat screen TV sets. Samsung has a full array of Smart Apps that run on their TVs. These Apps are small programs (similar to iPhone Apps) that run on the TV set. While some of them must be purchased for a small charge, there are quite a few free Apps. These cover a wide range of subject areas such as Lifestyle, Videos, Sports, Education, Games, and Information. There are also Apps that enable you to access the Internet, and to use services like Hulu Plus, Netflix, Pandora, and many others. The Samsung UN40D6400 set also features the "ConnectShare" Movie feature. This makes it easy for you to listen to music, run videos, or browse pictures from your USB Thumb Drive. Just plug the drive in the USB port that's on the TV set, and you are ready to enjoy your media files. Aside from all the electronic features, Samsung has also taken into consideration minimizing the impact of the room environment around the TV screen. They feature the "Ultra Clear Panel" on the front of their screens. This panel has a specially treated surface that absorbs light from the room.
This greatly eliminates those annoying reflections that might otherwise be present on the screen, and that would interfere with your enjoyment of those incredibly sharp pictures. There are many more interesting features of the Samsung UN40D6400 set that can't be covered here. These include the Eco Sensor, the Wide Color Enhancer Plus, DLNA AllShare, Micro Dimming, the Eco Sensor, and others.
