Looks good hifi, & you believe theres a home cinema version coming out?
Try this technology comparison:
"Other imaging devices, especially those based on liquid crystals, suffer
quality losses with increasing operating hours. The symptoms vary; there
may be fading colors, gradual increase of defects in color (“discolored
edges”), losses of homogeneity (the background becomes speckled), etc.
The introduction about five years ago of reflective liquid crystals based on
inorganic materials has brought discernibly higher image stability. However,
there is no secure testimony for long-term stability. It can be expected
that after two to three years of continual operation, similar degradation
effects will also influence the newer LCoS systems. In addition, LCoS
necessitates polarized light, which requires about double the wattage
of illumination, and accordingly, double the power consumption to
achieve the same brightness. The LCoS projection technology requires
special filters, which are wearing parts that need replacement after a
few thousand operating hours. Costs for filter cleaning and replacements
do not arise with DLP® technology."
