The Samsung Company has been in the forefront of the development of HDTV flat panel sets; it is one of the top brands available. Their newest sets include LED back-lighting technology, which eliminates the cold-cathode fluorescent tube systems that were included in the first generation of LCD TV sets. The development of this LED technology has enabled them to produce sets that are thinner, and lighter than previous sets, yet produce significantly higher picture quality. The Samsung UN46D6900W LED 3D HDTV is a good example of this technical superiority.
As a result of the fact that an LCD (Liquid Crystal Display) does not produce any light, but rather functions as a shutter that varies the visibility of light through the screen, any LCD display requires a back-light in order to be seen in dim lighting conditions. The LCD part of the display 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.
Therefore, while an LCD display can be viewed in bright light (a digital watch or clock face, for example), in order to be visible in conditions - or to produce a usable TV picture - there has to be a source of light behind the LCD display that supplies the necessary illumination - in other words, 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.
Using LED lighting makes it possible for Samsung to gain much tighter control over the brightness of specific areas of the screen. They have developed a system they refer to as "Micro Dimming", which permits them to change the level of the back-light from one area of the image to another, which means that the picture has more intense whites, and that the black areas are much darker and deeper than you will see with the older LCD sets, which are lighted with fluorescent lamps extending across the full width of the set.
6This TV set is extremely energy efficient: based on a watching the set for five hours per day, and an electricity charge of 11 cents per Kwh, it would only cost about $15/year to operate this set. When the set is not in use, it consumes just 0.07 Watts of power. That amounts to 0.6 Kwh/yr, which would cost less than $0.07 based on the same electric cost!
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.
While some of the "Apps" must be purchased for one or two dollars (similar to iPhone apps), there is a very wide selection of Apps that are free, including games and children's material. Apps categories cover areas such as Lifestyle, Videos, Sports, Education, Information, and Games.
Having this set will significantly enhance your TV watching experience, and will make it easy to interface with all your other media needs, from your computer to the Internet. There are many other great features to be found in this set - check the website linked in the resource box for lots more information.
