There is a lot of innovation in the electronic field. First there were TVs, then there were flat TVs, then real flat TVs, LCDs and now Plasma. Can anyone out there tell the difference LCD and Plasma. They say Plasma is better than LCD. Is it true? Secondly, what is the ration like 50000:1 that we see on the ads?

LCD and Plasma are both different types of technologies. Plasma eliminates the need for a bulky picture tube and electron beam scanning of traditional televisions. But because it burns phosphors to generate an image, the screens of plasma tvs are known to have the images "burned" onto the screen. They also generate heat. LCD uses crystals. Less power is needed and LCD generates less heat. Plasma tvs have a larger screen availability, better contrast ratio and the ability to render deeper blacks, better color accuracy and saturation and better motion tracking. LCD tvs have no burn-in of static images, cooler running temperature, no high altitude use issues, increased image brightness over plasma, longer display life and lighter weight. As for plasma being better than LCD, it depends on what you watch on your tv and if you really need that super huge screen or not. I'm sorry but I don't know what the 50000:1 ration is about.
