What does 1080i&1080p mean of lcd tvs?

• Answer:

  LCD TVs, like plasma TVs and other forms of modern TVs, offer images in high definition. The numbers "1080i" and "1080p" refer to specific levels of high definition: basically explaining how crisp and clear the picture is.Standard DefinitionOlder tube TVs offered 480 lines of pixels on each screen. That's considered standard definition.1080An LCD with 1080i or 1080p resolution has 1080 lines of pixels on each screen--twice as many as standard definition. That offers a correspondingly sharper and more vivid picture with any programs that broadcast in high definition.InterlacedThe "i" after the1080 means "interlaced." That means the image flickers back and forth between one half of the pixel lines and the other so quickly that the eye cannot distinguish the difference.ProgressiveThe "p" after the 1080 means "progressive." All 1080 lines broadcast simultaneously, producing the sharpest and clearest picture possible.The DifferenceThe difference between 1080p and 1080i is very subtle, but 1080p purportedly offers a slightly better image than 1080i.Source:http://reviews.cnet.com/1080i-vs-1080p-hdtv/http://www.bigscreen.com/about/help.php?id=47
