("panels" means "flat" in the display business) were select models from Hitachi and Fujitsu because they were based on the two companies' Alis and eAlis technologies. These panels were in fact interlaced plasma displays.

The only other 1080i displays are CRT, which can be found in rear projection, front projection and direct view models.

If a display is an actual/true 1080i display, then it cannot be a 1080p30 display. The reference to 1080p in display presentation can only be a progressive display -- interlaced displays cannot present 1080p by definition. That doesn't mean a 1080i display cannot accept a progressive signal (such as 720p or 1080p) and perform processing to present the progressive signal as an interlaced signal (its native mode).

Are you sure you're not confusing display type with the type of signal that a display can accept?

By the way, 1080p signals from satellite and cable (though slower to adopt) are not far off. Several companies are issuing converters that incorporate video decoders (mostly AVC/H.264) which will accept 1080p signals. For backward compatibility, these converters will be able to output a signal that's older-model-display friendly.
