Samsung has long been in the forefront of the improvement of HDTV flat panel sets; it is one of the leading brands available. 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 UN46D6900W LED 3D HDTV is an excellent illustration 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 works like a very tiny venetian blind: when the crystals in a display element are lined up perpendicular to the screen, light is able to pass through the cell, and it will be bright. If the crystals are aligned parallel to the display, the transmission of light is stopped, and the element 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 very efficient: based on a usage rate of five hours per day, and an electricity charge of $0.11 per Kwh, it will cost approximately $15/year to operate this set. When the set is on standby, it uses 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.
Owning this set will substantially enhance your TV viewing experience, as well as making it easy to work with all your other media, from your computer to your iPhone to the Internet.
