If you have looked at all the fabulous photos of an LED TV from this year’s catalogues and are set to buy one for yourself, it will really be helpful in your purchase if you know a few facts about the technology first. The LED TV had a great reception at this year’s CES Trade Show and Samsung was the first one to actually have brought the technology into the market with its Samsung 7000 television set range.
Simply put an LED TV is actually an LCD television which incorporates an additional technology. LEDs are light emitting diodes which are an efficient light source and while previously other methods of lighting up the LCD screen were used such as fluorescent tubes, now the LEDs are utilized to light up the LCD display.
While fluorescent tubes provide light, they have a few drawbacks. They take up more space and are heavy in weight. Also they do not provide sufficient color quality because the blacks displayed are not true blacks and this reduces the vibrancy of all other colors. This is basically why the LED technology came along – so they could provide a lighting source that can show the purest blacks and whites.
At the present there are a couple of LED TVs available to the consumer. One of them is back-lit model which allows the LCD display to be lit up by back lighting through a number of LEDs placed behind the television panel. The other one is the break through edge lit version which uses LEDs as a light source positioned around the edges of the television screen. Using LEDs as back lights requires a lot of space in the back of the television set, making the LED TV thicker in size. The edge lit LED display however, requires less back panel space and hence the designs are much slimmer and sleek.

The long awaited Apple tablet has finally been revealed. Steve Jobs pulled the wraps off on January 27th in a tense morning for Apple and tech fans all over the world. Now with the specifications and information out there it’s time to preview the iPad and its potential.
First of all the design is pretty spectacular. The front is dominated by the large 9.7″ LCD Led lit display that without a doubt will look great. Just below the screen you get the iPhone home button that allows you to go back to the beginning at all times. One less pretty feature for me are the black borders around the screen. They are a bit too wide for my taste, it would’ve been better if Apple was able to stretch the display a little and remove the borders. On the top you get the sleep button that will deactivate the display. On the right side you get the volume buttons and the silence switch, interesting is that the buttons have been moved from left (iPhone) to the right. On the back you get the large black Apple logo in the middle of a big gray (aluminum?) mass. It also says iPad on the back, the number of GBs and a few FCC things that are required to be there I think. It’s not impossible to assume that the new iPhone will feature a similar back. The tablet is really thin, in fact it’s just 0.5 inch thick, that’s as thick as an iPhone. Height and width measures come in at: 9.6 inches and 7.47 inch.
Now lets talk about the software of the iPad. It works very similar to an iPhone. Slide to unlock and you’re in the main screen with the typical iPhone icons. You get: YouTube, mail, Safari, contacts, iPod, iTunes, app store, video, settings, maps (by Google!), calendar, photos and last but not least notes.
The apps have been modified a bit for the new capabilities though. For example photos are now arranged by event blocks. Tapping on a block of photos will show you a preview of the photos in that event (or map for windows users). However you can also view your most treasured memories by list, location, faces or date. We can imagine that it will look really fantastic to manipulate the photographs on a huge touchscreen and to show it to your friends.
