Samsung has become one of the leaders in the commercialization of flat panel HDTV technology. Their latest sets include LED back-lighting, which replaces the fluorescent lighting systems that were used previously for LCD TV sets. The use of LED technology has made it possible to produce HDTV sets that are lighter and thinner than previous sets, and also produce significantly better picture quality. The Samsung UN40D6420UFXZA LED 3D HDTV is an example of this high quality.
Because an LCD (Liquid Crystal Display) does not produce any light, but rather acts as a shutter that controls the passage of light through the display, all LCD displays require a back-light in order to be seen in dim lighting conditions. The LCD part of the display simply acts as a "shutter" that either allows light to pass through the display panel, or blocks it. It is like a microscopic venetian blind: when the crystals in a display cell are aligned in a perpendicular direction relative to the screen, light can pass through. When the crystals are aligned parallel to the display, the passage of light is blocked.
While an LCD display can be seen in bright light (for example, a digital watch or clock face), in order to be seen in dim lighting conditions there must be a light source behind the LCD display screen that provides illumination, in other words, a back-lighting system. The first LCD TV sets were back-lit by a fluorescent tubes, which provide white light. Each picture element or"pixel", that is used to create a TV picture is small spot in the display that contains three microscopic filters that provide the primary TV colors: red, green, and blue (the familiar RGB you've seen in TV specs).
The color TV picture is then created by adjusting the transparency of the LCD element that controls the light passing through each of the filters in each of the pixels that make up the entire picture. For a typical HDTV picture, there are 1080 lines of pixels, each with 1920 pixels per line - a total of over 2 million pixels in the picture. Each pixel has three filters, and must be controlled individually to create a single frame of a TV picture, which refreshes at a rate of either 120 Hz, or 240 Hz, depending on the model. The notation Hz refers to "Hertz", which is a measure of the number of "cycles per second" - 1 Hz is equal to 1 cycle per second.
The Samsung UN40D6420UFXZA LED 3D HDTV set uses an "edge lighting" technique to supply back-lighting for the picture. In this method of back-lighting, high intensity white-light LEDs (Light Emitting Diodes) are placed along the edges within the display screen . A diffuser plate distributes that luminescence through the entire face of the display. The employment of an LED illumination system means that the TV requires a lot less power to use. This set is quite efficient: based on an operating rate of 5 hours each 24-hour interval, and an electricity rate of $0.11 each Kwh, it will cost you about $14/yr to operate it. When the tv set is not running, it consumes just 0.07 Watts of electricity. That amounts to 0.6 Kwh/yr, which is cheaper than $0.07, assuming on the very same power prices - no "electricity vampire" here!
Among all the other great Specifications, this UN40D6420UFXZA Samsung set is loaded with something that Samsung refers to as "Smart Apps" - apps which are the actual foundation of their "Smart TV" system. All these "Apps" permit you to use the Television set to interact with the Internet, and download content from the Web from providers like Hulu Plus, Netflix, Pandora, and many others.
An additional feature of this set is its "Allshare DLNA Technology". DLNA is an abbreviation that stands for "Digital Living Network Alliance". It represents an "interoperability protocol" that enables various electronic products to be linked with each other to allow file sharing and data communication. Samsung's "Allshare" renders it a cinch to link your DLNA-enabled devices with this Samsung TV set, which allows you to use the various media files on your pc, iPhone, along with other components with your HDTV set. Add to that the optional LinkStick, and you will be able to enjoy wi-fi accessibility in addition.
The Samsung UN40D6420UFXZA set also includes the ConnectShare Movie feature. This makes it possible to play music, watch videos, or look at pictures from any USB Flash Drive. All you need is to is to plug the drive into the USB port on the set, and you are ready to go.
The clarity of the picture you will see on the Samsung UN40D6420UFXZA is enhanced by the Ultra Clear Panel which forms the front of the screen. This panel absorbs ambient light from the surroundings, which in turn almost totally eliminates the annoying reflections that would otherwise appear on the screen. This in turn provides a picture with deeper blacks and enhanced contrast, providing a cleaner, crisper image with great shadow detail.
Having this set will greatly improve your TV watching enjoyment, and will make it easy to interface with all your other media, including your computer, other personal devices, and the Internet.
