Pros and Cons of different technologies


LCD
Pros:
Low power consumption.
Can give good pictures
HD capable screens are easy to get
Cost
Size (Large screens are still relatively thin)

cons:
Cheaper screens can suffer smearing in scenes with a lot of action.
Screens can have bad contrast
Can have a bad viewing angle (the picture may be good if you are looking straight at it, but what happens when you are slightly off centre).

Plasma
Pros:
Good picture quality
Excellent viewing angle
HD screens easy to obtain
Size (Large screens are still relatively thin)

cons:
Power consumption (Plasma uses twice the power of an equivalent size CRT and 4 times the power of an equivalent size LCD).
Cost

CRT
Pros:
Excellent picture quality (IMO beats plasma assuming the resolution is the same).
Good viewing angle.
Cost (it's seen as "Yesterday's Tech" so it's a lot cheaper)

Cons:
Power Consumption
Size (CRTs tend to be a lot deeper than LCDs or plasmas so take up a lot more space).
Availabilty (CRTs are increasingingly hard to obtain, especially HD compatible ones). Partly because of this, CRTs aren't really practical for screen sizes larger than 32 inch.

Can't really comment on OLED, as there aren't a lot of TVs using it at the moment, and I haven't seen one in the flesh.

Supposedly it offers a picture comparable to CRT with a power consumption lower than that of LCD, and even at large screen sizes should be thinner than LCDs or Plasmas.

Also, just to confuse you further, I read a while back that one of the large Electronics companies (Samsung I think) was working on "Short Necked CRTs" that offered all of the advantages of CRT, and HD but in a package that is considerably thinner than a standard CRT.
