Sim2 Multimedia DLP Video Projector C3X Link - Manual (Page 5)

How it works and advantages:
DLP® technology-enabled projectors
for very high image quality or high
brightness applications such as cinema
and large venue displays rely on
a 3 DMD-chip configuration
to produce stunning images, whether
moving or still. In a 3-chip system,
the white light generated by the lamp
passes through a prism that divides it
into red, green and blue.
Each DMD chip is dedicated to one of
these three colors; the colored light
that the micromirrors reflect is then
combined and passed through the
projection lens to form an image.
3-chip DLP®-system:
The Grand Cinema™ C3X series
utilizes Texas Instruments’ HD2+
DarkChip™3, commonly referred
to as the DC3 chip. The DC3 chip
embraces a series of refinements
aimed at enhancing performance
and delivers all the detail available
from today’s high definition
sources without the usual
‘pixilation’ or ‘screen door’ effects
that afflict other projector
technologies.
DC3 chip in detail:
A DMD chip contains an array of
hinged microscopic mirrors that
recreate a video or graphic image
by reflecting light onto a projection
surface (screen). When a DMD
mirror tilts away from its light
source, a tiny space is opened into
which stray photons can stumble.
In first-generation DMD systems,
these particles of light occasionally
escaped to screen, subtly
affecting the contrast ratio of the
projected image. In the
DarkChip™ DMD generation, a
light-eating "dark metal" coat is
applied to the interior of each chip,
preventing stray light from
traveling to screen when the
mirrors are switched off. The
unique features of the
DarkChip3™ (reduced via size and
pixel gap) reduce the scattering of
light, resulting in increased image
contrast (+25%) and an improved
black color point / perception of
black. Also, the DarkChip3™ is a
Fast Track Pixel (FTP) chip that
allows approximately 50%
reduction of the detrimental
‘dithering’ effect, for an
exceptionally natural, crystal clear
image.
