All flat panel sets, LCD, DLP or Plasma, are progressively scanned. That means every pixel is updated 60 or 120 times a second. All interlaced 480i or 1080i inputs from the tuner or any other input is converted by the set to a progressive signal before being displayed on the screen.
All LCD sets on the market today have either 768p or 1080p panels. Some of the 768p sets can accept 1080p signals from HDMI or component sources. All 1080p sets today can accept 1080p signals on their HDMI inputs. This may be true of all DLP and plasma sets and is certainly true of most of them.
A 1080i flatpanel set is simply a set which cannot accept 1080p signals and today is a 768p set. If the set did not have a 1080p panel there would be no value in its accepting a 1080p signal since it would still have to convert the signal to 768p. All HD sources can can provide 1080i and 720p signals. For this reason even an older set with a 1080p panel which cannot accept 1080p functions just fine using the 1080i signal from a BD player. (I have an excellent 46 in 1080p JVC made in 07 which won't accept a 1080p signal but works great with my Toshiba HD player.) I hope this helps explain the "1080i" set.
