sharp, clear picture with the smooth, high-definition
quality you see in a movie theater. The ALIS Method
employs a screen surface comprised of vertical channels
of continuous phosphor material. The pixels are defined
electronically rather than physically, allowing each
picture element to be smaller than normal. This creates a
higher pixel count for a smoother, seamless picture, with
edges and curves clearly defined. The PDM-4210 uses the
latest ALIS Method technology, which features new
plasma gas and luminescent material that are more
effective than previous types. The result is a brighter
picture (1,100 cd/m
2
) and higher color temperature,
which makes white areas such as clouds in the sky stand
out more vividly. The panel can also display a wider range
of colors (16.7 million), with enhanced color purity.
Natural Black Drive System
The Natural Black Drive System automatically
determines the brightness of the screen and applies the
gray scale (contrast) best suited to the scene in order to
reproduce both bright and dark areas with small details
clearly visible. The contrast ratio is an outstanding
1,000:1 under daylight condition, making it possible for
the PDM-5520/PDM-4210 to deliver sharp, natural-
looking images.
Digital Linear Color Control
Digital Linear Color Control continually maintains the
ideal balance between the three main colors (red,
green, blue) for optimum color reproduction in every
scene from very dark to very bright. The sharpness and
tint of each color are independently controlled, so you
can adjust the tint more precisely.
Long Life of 60,000 Hours
Another benefit of the e-ALIS/ALIS Method Panel
technologies are lower power consumption and longer
panel life. The Yamaha Plasma Display Monitors will
provide high quality images for 60,000 hours,* about
twice as long as a typical CRT monitor.
* Until panel brightness reduced to 40%. Yamaha measurement.

DPX-1200: Advanced technologies
deliver extraordinary performance.
"Natural Black" Concept
To provide superior
contrast, Yamaha has developed the Natural Black
concept, combining advanced technologies, parts and
functions to achieve truer, deeper levels of black than
ever before.
Taking Projector Performance to a New Level
The DPX-1200 makes use of a wide range of new
technologies to deliver extraordinary video
performance. Contrast is an incredible 5,000:1,
brightness is 800 ANSI lumens, picture sharpness is
outstanding and color reproduction is stunningly
natural.
Newest Light Engine: 720P
DarkChip3™
This DLP chip is Texas Instruments
newest and most advanced Digital
Micro Mirror Device. As the name
implies, it provides deeper blacks and
improved contrast in dark areas.
Seven-Segment Color Wheel
The DPX-1200 incorporates a
seven-segment color wheel, with
an ND filter-equipped green
segment, resulting in excellent
color reproduction. The seven-
segment structure reduces dither,
while color reproduction is excellent, with greens
being more true to life than ever (achieving the HD
monitor “green” standard). Green resolution is 10-bit,
which also improves the representation of black tones.
LPX-510: “Natural Black” and
advanced functions for enjoying
widescreen movies.
High Performance LCD Panels
The LPX-510 uses LCD panels capable of projecting
high resolution 720p HDTV images and 10-bit video
processing gives it the ability to reproduce 1.07 billion
colors. 16:9 aspect ratio compatibility means that
widescreen movies can be viewed in their entirety.
3D Linear Color Balance
The 3D Linear Color Balance function maintains the
proper balance between the three signals from the
LCD panels, adjusting color irregularities through a
range of 15,360 correction points for accurate color
in any type of scene.
Lens Shift, Motorized Iris and Zoom
Vertical and horizontal
lens shift capability means
that the projector does
not have to be positioned
directly in front of the
screen. The motorized iris
control can be used to
improve contrast and
focusing, and the motor-
ized Zoom will expand the
image up to 1.5 times.
PDM-5520 and PDM-4210: Yamaha
Plasma Display Monitors use the most
advanced technologies to deliver
superb performance.
e-ALIS Method Panel Technology (PDM-5520)
The PDM-5520 uses a highly advanced e-ALIS
Method (extended Alternate Lighting of Surface)
panel whose pixels are defined electronically rather
than physically, allowing each picture element to be
smaller than normal. This creates a higher pixel count
for a smoother, seamless picture. The panel employs
new plasma gas and luminescent material that are
more effective than previous types, and the area
coated with the luminescent material is greater. This
results in the industry’s highest level of brightness,
1,000 cd/m2, with the ability to display 1.07 billion
colors for spectacular color richness and purity.
ALIS Method Panel Technology
This plasma display panel uses an advanced ALIS
(Alternate Lighting of Surface) Method to deliver a
Black reproduction by DPX-1200 and conventional projectors.
Yamaha Natural Black makes
subtle degrees of black in
textures, shadows stand out
more clearly.
With other projectors, black
contrast may be soft and
fuzzy rather than sharp
and clear.

e-ALIS Method Panel Technology
The e-ALIS (extended ALIS) Method Panel technology was developed
to enable the use of the ALIS Method on large screens. Adopting
the shared electrode structure that is a special feature of ALIS on
the front panel permits the display of highly detailed images of 768
lines with 384 electrodes. 1/60 second (1 field) is divided twice into
odd number lines and even number lines to perform address, then
emits all pixels. During the next 1/60 second, the same operation is
done to display a 1/30 second image (1 frame).
The Natural Black Drive System allows the PDM-5520/PDM-4210
to outperform other plasma displays with deeper blacks and
sharper overall contrast.
