Do rear projection televisions have inherently different scan and
flicker characteristics than single tube direct view televisions? I
notice the rear projection models seem easier on the eyes than even
big tube direct view sets. Is this because the RPTV units have 3 guns
vs. one big tube?

direct view screens have three guns too... just in one glass envelope

but the big difference is that RP's don't have shadow masks - thus no dead
space around pixels

BUT those dead spaces tend to add a artifact, a very high spatial frequency
pattern overlaid on the image - like plasma or LCD while RP's tend to
smoothly transition from pixel to pixel (due to less-than-perfect focus in
both electron beams and optics).

Most RP's also put out less light per square inch than a direct view.
