D-ILA and LCOS are synonymous, D-ILA being the JVC tradname,
LCOS - Liquid Crystal on Silicon being the generic name.
DLP is the Texas Instruments tradename, while
MMD - Micro Mirror Device is the generic name.
That 1365 X 1024 native resolution is the same as the
JVC 0.9 inch SXGA+ chip found in the JVC badged projectors.
If memory serves, in reading JVC's literature, the new
0.7 inch SXGA+ chip has a different pixel structure than
the 0.9 inch chip. Hitachi may be using the same 0.9 inch
chip that the JVCs use - not the smaller one.
If I recall, Hitachi's "progressive scan technology"
is a way of utilizing a single LCOS chip instead of the
3 chips in a JVC unit. The different colors are
progressively scanned across the chip in lieu of a color
wheel as used in 1 chip DLP units - but is functionally
equivalent.
It would also be nice to know what type of lamp the
Hitachi uses. If they use Xenon like JVC, then they have
the same nice high color temperature - but have the same
cooling problems as a JVC. If they use a cooler lamp
technology - as JVC does in the DS1 [ formerly 3010Z ],
the lamp is easier to cool, but you sacrifice the nice
high color temperature. [ The moral of that story is that
there's no free lunch. ]
