HDTV refers to the signal being transmitted. It the latest standard that has better a better picture and sound than the old standard which is called SDTV.
LCD, LED, and Plasma refers to the the type of televisions which displays these HDTV signals. HD-Ready TVs mean they have a high resolution display and can have a built-in over-the-air HDTV tuner.
LCD uses liquid crystals and a flucent tube backlight to display the image. Pros of LCD are bright picture and low power consumtion. Cons of LCD are low contast, motion blur, narrow viewing angle.
LED tvs are similar to LCD because they both use crystals to display the picture. The differences is that LED uses LED for the backlight instead of flucent tubes. Pros of LED are better color. Con of LED is poor uniformity, which means the brightness is uneven.
Plasma uses charged gas to display the picture. Pros of Plasma: best contrast, no motion blur. Cons: more power consumption, less detail in picture, minor problem of burn-in.
Now, the thing to remember is that technology is always changing and in some cases improving, so the cons of some TVs are less of problem than they used to be. For example, LCDs now have faster refresh rates which reduce noticable motion blur.
So the one you choose for your home depends on a lot of factors. If you have bright room, you may want a tv with lower contrast(the difference between light and dark). If you have a lot of money and want the latest technology, you may want LED.
If you want an overall good picture but aren’t concerned with sharpness, you may want Plasma.
