LCD or LED TV?

I was with my cousin yesterday when we hit the mall to grab for some highly discounted products when i decided to visit an appliance center shop. I really love going here and check the high tech gadgets being showcased there. I saw that they are offering huge discount for their LCD TV. I am really confused about the difference between an LCD TV and a LED TV. I wonder which is much better too. I did some research online and i found out that LED TV is the improved version of LCD. I also heard that LED TV is much better because it is more energy efficient than LCD. They are also made to provide high quality pictures that are greater than what LCD TV can provide.
But of course, LCD televisions are way cheaper than the LED TV but other than that, i cannot see too much of a difference between the LCD and the LED TV. Both of them are great and will definitely give you that entertaining watching experiences that you've been looking for.
There's nothing too much difference between the two unless we are referring about the brand. Some gadgets today are being imitated by other companies so it is better to buy your item from well trusted online shop or tv dealer.
So how about you? Which do you prefer? LCD or LED TV?

Evolution of Technology

Technology evolves from time to time and it’s very uncontrollable. We can do a lot of stuffs using the internet. From a simple Search engine, it turns out to become a multi-purpose tool for everyone. Some used the Internet for business purposes while others used it for fun and entertainment. For game lovers, we can download computer games with a great and wide selection using the net. You can also buy mac games if you’re using Macintosh. For music lovers, there are sites that offer great production music online and allow you to download music files for your mp3. For aspiring writers, there are plenty of social networking sites that offer micro blogging that allows them to express their thoughts and share their articles online. We can do a lot of things through Internet and I wonder what will happen to this technology ten years from now.
