Thanks in part to the pitch of the SXRD pixels, Sony projectors do not use
an optical actuator. Each pixel has its own, unique space on the screen, not
shared with any other pixel. And the SXRD system displays all the pixels, all the
time.
Spatial Dithering. Some projection systems use electronic processing to
conceal resolution limitations and deliver a subjectively pleasing picture on
typical moving images. But the action of these circuits can be glaringly obvious
during motion picture credits and other fine text applications. The Sony 4K
projectors do not use this type of processing. In addition, as a natural
consequence of their lower resolution, 2K projectors will also exhibit aliasing and
black dither noise on images while SXRD 4K projectors do not.
With three separate microdisplay panels and no optical actuator, Sony
SXRD projectors display all the colors, on all the pixels, all the time. And with a
minimum of electronic tricks, those pixels are extremely faithful to the original
source. Unwanted artifacts are kept to a minimum.
