samsung 40d6400 led 3d hdtv set - a good choice for small rooms
It has been a top-selling manufacturer of flat-screen televisions for years.
By the beginning of 2011, Samsung had sold 30% more flat-screen TVs than its closest rivals.
Anyone who has seen Samsung hd TV will not be very surprised by the fact.
The clarity and clarity of the photos they took were amazing.
Combining this with very high technical complexity and the wide range of features Samsung has included in its set, you can offer a very compelling package for anyone considering buying a hd TV. . . .
This is before you consider the active 3D aspect!
Samsung uses what it calls \"active 3D\" for its full range of HD TVs \".
This is one of the ways to create 3D TV images in TV sets currently on the market.
Another way to solve the 3D problem is called \"passive 3D \".
There is a very important difference between the two, which is displayed in the observed quality of the displayed image.
The process required to create an image on a screen with a depth sense is often called 3D dependent on the stereo principle, viewing the visual effects of different images with each eye.
To see an example of how this works, try this quick experiment.
Raise an object (
Or just your fingers)
At the length of the entire arm, look at it with your right eye and then look at it with your left eye.
Alternate the eyes you look back and forth.
When you do this, when you compare an object with an object farther away from you, please pay attention to its obvious position.
You will notice that when looking through the right eye, the object appears to be positioned on the left side of certain objects in the background, but when you look through the left eye, relative to that background object, the relative position of the object will be treated as moving to the right.
This visual illusion is called, and it is the basic principle of two systems used to produce 3D effects on a TV or movie screen.
The important difference between active and passive systems is how to pass the two stereo images to the correct eyes. The three-
Only when each eye sees the correct image and only the correct image can the size effect be seen. (
Think back to your previous point. Master).
As you may have seen, if you watch 3D movies or TV images without 3D glasses, you will see double images.
To achieve a 3D effect, your brain must see images that are completely different from each eye, and the images you see have the appropriate parallax.
Glasses used by passive systems for displaying 3D images have a polarization filter of 90 degrees relative to each other.
The picture on the screen is also polarized through a polarized filter, alternating scan lines in two directions corresponding to the lens in the glasses.
For hd TV images of 1080 horizontal lines per frame, therefore, 540 lines are polarized in one direction to produce images seen in the right eye, the other 540 alternating lines are polarized in the opposite direction of 90 degrees, for the left eye.
The result of this is that what you see is an image with an effective resolution of 540 lines, just half the resolution needed for a 1080 line Real hd TV.
Using the activity system, the image of each eye is alternately displayed, first the right eye and then the left eye.
These alternate frames appear on the screen at least 120 frames per second.
Obviously, if these alternate images are observed without proper filtering to ensure that only the appropriate eyes can see the appropriate images, the result must be a double image.
To ensure that only the correct image is visible to each eye, the active system uses the glasses of the LCD filter.
By turning on or off the LCD filters, these can change from transparent to opaque.
Glasses use Bluetooth signals sent by the TV to coordinate the switching of lens filters and the display of images on the screen.
Since the image of each eye uses all 1080 lines on the screen, each eye can see the full 1080 lines of the image, just half the time.
Like all Samsung 3D HD TVs, the Samsung UN40D6400 uses an active 3D approach.
In addition to the excellent 3D TV, this TV has a range of other elegant features that make it your complete media center.
It uses LED edge lighting to provide lighting for pictures (
Because the LCD does not produce any light).
Replace the fluorescent lamp in this system (yes, really! )
Used in the last generation of LCD flat panel TVs.
There are a variety of smart apps on Samsung\'s TV.
These applications are small programs (
Running on the TV.
While some of these apps have to charge a small amount, there are quite a few free apps.
These courses cover a wide range of subject areas such as lifestyle, video, sports, education, games and information.
There are also apps that give you access to the Internet and use services like Hulu Plus, Netflix, Pandora, etc.
Samsung also launched the \"ConnectShare\" movie feature.
This makes it easy to listen to music, run videos or browse pictures from a USB thumb drive.
Simply plug the drive into the USB port on the TV and you\'ll be able to enjoy the media files.
In addition to all the electronic features, Samsung also considers minimizing the impact of the room environment around the TV screen.
They have a \"super clear panel\" in front of their screen \".
This panel has a specially treated surface that absorbs light from the room.
This greatly eliminates the annoying reflections that may appear on the screen, which will interfere with your enjoyment of those very clear pictures.
There are many interesting features in the Samsung Series that cannot be introduced here.
These sensors include Eco sensor, wide color booster Plus, DLNA all share, fine-tuning light, Eco sensor, etc.
