Presentations in Light
Micro Portable XGA LCD Projector
PT-LB20U
XGA
2000lm

Many people want to use spe-
cial colors and designs in
their presentations, but these
colors change when they’re
projected onto the screen in a lighted
room. So they just use plain, basic colors.
As a result, the presenta-
tion is visually
boring and looks
just like their
competitor’s.
Panasonic
solves this prob-
lem with our
micro-portable pro-
jector featuring
innovative Daylight
View technology. The
PT-LB20U greatly
improves image per-
formance in brightly lit
places. In fact, the
2,000-lumen brightness
of the PT-LB20U achieves a level of image
performance that equals many 3,000-
lumen projectors.*1*2
Image Performance rivaling
3,000-Lumen Projectors
Daylight View technology significantly improves
image performance. Our new 2,000-lumen pro-
jectors have attained a level of image perform-
ance that equals or exceeds that of our previous
3,000-lumen models
in brightly lit envi-
ronments.*2
Vivid colors in a Bright Room
Panasonic designed and adjusted its projector
image display based on use in a well-lit room in
developing Daylight View technology. This tech-
nology greatly improves color perception in bright
rooms. Pale colors are divided into six basic color
components (red, green, blue, yellow, cyan and
magenta) for more precise control. Daylight View
achieves a superb level of image performance
that produces less of a difference
between PC display images and project-
ed images.
Auto Operation with Ambient
Light Sensor
The top panel of the unit is equipped
with an ambient light sensor (ALS).
The ALS detects changes in the
ambient light intensity and optimizes
color compensation in four steps
according to the environment. The
Daylight View mode also provides
white balance adjustment settings
for both fluorescent and incandes-
cent lamps to match the room
lighting.

Daylight View technology
enables Panasonic projectors to
achieve the same image per-
formance as projectors a class above
them, while consuming less power. This
helps to save energy resources that
would otherwise be wasted.

tions of 400 lux, when projecting an 80-inch image (meas-
ured diagonally)
*2The Daylight View effect may vary depending on screen size,
screen gain, and surrounding brightness.
*3The projector cannot be placed into a bag until the
cooling fan stops operating.
2-Second Speed Start
Speed Start slashes the time it takes to get your
presentation under way. The image appears with-
in two seconds after you press the power button.
Behind this breakthrough is Panasonic’s high-pre-
cision lamp and lamp power supply—an
advantage made possible by our
advanced production technology.
One-Touch Auto Setup with
Digital Keystone Correction
This function assures quick and easy
setup. The projector handles the basic
image adjustments, from phasing to
vertical and horizontal position. The built-in gravi-
ty sensor detects the projector’s angle relative to
the floor and corrects for vertical keystone distor-
tion accordingly.
Direct Power Off
When the presentation is completed, Direct Power
Off lets you disconnect the power cable and move
the projector right away*3because the cooling fan
keeps operating until the lamp is cooled.
Notebook-Size Compact Body
PT-LB20U is 11-11/16˝ wide by 8-1/4˝ deep—
about the size of a sheet of paper—and only
2-9/16˝ high. It slips easily into a bag or brief-
case. The compact size makes the PT-LB20U
highly mobile and minimizes the space required
for presentations or storage.
Ultra-Lightweight: 4.6 lbs (2.1 kg)
At only 4.6 lbs, PT-LB20U won’t weigh you
down — even when you’re toting along a note-
book PC as well. Convenient size and weight are
just two reasons why the PT-LB20U is the logical
choice for mobile presentations.

Panasonic meticulously works to minimize environmental impact in the prod-
uct design, production and delivery processes, and in the performance of the
product itself over its life cycle. The PT-LB20U reflects the following ecological
considerations.
• Lead-free solder is used to mount components to the printed circuit boards.
•No halogenated flame retardants are used in the cabinet.
• No styrofoam is used in the packing materials.
•Lead-free glass is used for the lens.
•The packing case and operating manual are made from recycled paper.

NOTES ON USE
• The projector uses a high-voltage mercury lamp that contains high
internal pressure. This lamp may break, emitting a large sound, or fail
to illuminate, due to impact or extended use. The length of time that it
takes for the lamp to break or fail to illuminate varies greatly depending
on individual lamp characteristics and usage conditions.
•The brightness of the lamp will gradually decrease with use.
• The lamp, LCD panel, polarizing plate, and polarizing beam splitter
(PBS) are consumable parts. These parts may need to be replaced dur-
ing the guarantee period if the projector is used for six or more hours
per day.
• The replacement cycle of the LCD panel, polarizing plate, and polarizing
beam splitter (PBS) will be shortened if the projector is subjected to
continuous use for six or more hours. Likewise, the replacement cycle
of the lamp will be shortened if the power is frequently turned on and
off or the projector is subjected to continuous use for 10 or more hours.
