You are trying to mix to totally different things.
LCD stands for liquid crystal display. It is describing the mechanics of how the picture is displayed. Some LCD TV's are HD and some are not. Mechanically you have different types of displays; Plasma, LCD, DLP, Projection, and CRT.
Just about all manufacturers make lower model (non HDTV) and higher model (HDTV) The quality is what determines the HD or not. Older models provide approximately 720x420 which translates to 720 dots per row and 420 rows. In older sets the lines are interlaced, it put line 1,3,5,7 and so on then comes back and puts lines 2,4,6,8 and so on. It does this very fast so the human eye doesn't notice it.

The true format of an HDTV is 1920x1080p, that is 1920dots across each line and there are 1080 lines and the line format is progressive, in other words it puts out line 1,2,3,4,5 and so on. Remember the i was interlaced1,3,5... and then 2,4,6...
For a TV to be classified it only has to meet a portion of the final and that is 1280x720p. Still much, much better than standard tv (SDTV). I know that this is confusing, and it will probably change again before everyone understands it, and there are a lot who don't understand yet.

There really isn't a difference between LCD and HDTV's. Many LCD tv's are able to project HD images. HDTV's are simply able to show HD programming, LCD tv's are simply a type of television.

It's the difference between SDTV and HDTV.

HDTVs have, at optimum, 6 millon RGB dots for a total of 2 million pixel clusters.

SDTV needs only 1 million RGB dots for 333,333 pixel clusters.

For any TV, LCD, Plasma, etc., to be considered HDTV it must have an HDTV tuner and at least 1 million pixels (3 million dots).

They also need to play 720p or 1080i scanning rates.

LCD is "Liquid Crystal Display, they are alternative to a color tube television. You can get HD LCD tv's or you can just have regular LCD tv's.

LCD and HDTV is not comparable, because one is actually a feature of another.
