What is the difference between LCD and LED TVs?

With technology changing and advancing at a rapid pace, it's easy it lose track of new or improved electronics. Television is a great example of this -- in the past five years, liquid crystal display (LCD) televisions have overtaken a market that was dominated by cathode ray tube (CRT) televisions for nearly a century. Though LCD TVs are the best-selling in the world, light emitting diode (LED) TVs are quickly rising in popularity. While the two types of televisions might seem similar, there are many things that set them apart. In this webcast, learn about the differences between LCD and LED TVs, and which one might be right for your next television purchase.

Cathode Ray Tubes can display HD images. Resolutions much bigger than 1080P as well. Their demise was the LCD becoming better/cheaper and allowing much bigger screen sizes. CRTs will still produce a much better image. So your comment that CRT could not achieve HD image is incorrect.

You are comparing LED and LCD to CRT rather than than LED to LCD. Bad presentation. Confusing since I have to sort out of it the difference between LCD and LED. CRT are a history so why to bother to even mention it in this presentation.
