Hours of
Continuous Operation
This new light source requires no maintenance
for approximately 20,000 hours.

In many
cases, this means no maintenance until your
next refresh cycle. Naturally, there are no lamp
burnout problems during use, so reliability is
further increased. There is also no filter to clean
due to carefully engineered sealed optics. As
a consequence, running cost is dramatically
lowered because of the savings on lamp
costs, maintenance labor and hassle of
stocking lamps.
Bright, Beautiful Picture Quality for a
Long Period of Time
The PT-RZ370/RW330 features 3,500 lumens of
brightness. Rate of brightness deterioration in
the LED/Laser-combined light source is extreme-
ly slow compared to lamp based projectors. The
SOLID SHINE drive uses a built-in sensor to
constantly detect the light intensity of the light
source and correct corresponding changes in
white balance. This all helps to maintain excel-
lent picture quality for a long period of time.
Contrast is outstanding too, at 10,000:1, and
images are reproduced with a wide dynamic
range. The PT-RZ370 features a Full-HD (1920
× 1080) DLP
™
chip, allowing highly detailed
Full-HD images without resizing.
Superior Color Reproduction
The LED/Laser-combined light source has a
higher level of color purity than an ordinary
lamp, allowing it to achieve color production
with wider color space. Colors are more vibrant
than those of conventional projectors.

Switching Prevents Color
Breaking
In 1-chip DLP
™
system projectors with conven-
tional lamp, a color wheel is used for time-divi-
sion multiplexing in a method where the human
eye combines the result to achieve a full-color
palette. In the PT-RZ370/RW330, this is done by
on/off switching of the LED/Laser-combined light
source. A unique Panasonic power supply circuit
provides time-division multiplexing with ultrafast
30× drive.

The resulting, high-definition images
exhibit virtually no color breaking.

Heat Pipe Cooling System Maintains Stable
Operation up to 45 °C (113 °F)
*
5
Laser cooling is performed by releasing the heat
to cooling fins, then cooling with a heat pipe
cooling system. This suppresses temperature
rises inside the projector and allows stable
operation up to an ambient temperature of
45 °C (113 °F).

The use of this heat pipe-
cooled system also achieves quiet operation of
29 dB,
*

enabling viewers to concentrate on the
presentation or on quiet movie scenes.
Dust-Resistant Structure with an Airtight
Optical Block
The area between the LED/Laser to the DLP
™
chip and prism is hermetically sealed to form an
airtight structure for the optical block, the heart
of the projector. This resists the effects of dust
and other particles in the air, and enables use of
the projector in a wide range of environments.
The Daylight View Basic Ensures Clear
Images Even in Brightly Lit Rooms
0ANASONICS $AYLIGHT 6IEW "ASIC TECHNOLOGY
achieves sharp, easy-to-see images by clearly
reproducing the details in dark image areas,
which were previously difficult to see in brightly
lit rooms. A built-in sensor measures the ambi-
ent light, and the Daylight View Basic function
adjusts the halftone color and brightness level
according to the surrounding illumination.
DICOM Simulation Mode
*

This imaging mode is similar to DICOM part 14,
which is a medical imaging standard. It repro-
duces X-ray images with remarkable clarity.
Rec. 709 Mode for HDTV Projection
Optimal color reproduction can be achieved by
selecting this mode, compliant with ITU-R Rec-
ommendation BT.709, when images from an
HDTV source are projected.
