ivid colors in a Bright Room
V
Panasonic designed and adjusted its projector
image display based on use in a well-lit room in
developing Daylight View technology. This technology 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 displa
ed images.
Auto Operation with Ambient
Light Sensor
The top panel of the unit is equipped
with an ambient light sensor (
The ALS detects changes in the

2-Second Speed Start
Speed Start slashes the time it takes to get your
presentation under way. The image appears within two seconds after you press the power button.
Behind this breakthrough is Panasonic’s high-precision lamp and lamp power supply—an
advantage made possible by our
advanced production technology.
ouch Auto Setup with
One-T
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 gravity sensor detects the projector’s angle relative to
the floor and corrects for vertical keystone distortion accordingly.
Direct Power Off
When the presentation is completed, Direct Power
Off lets you disconnect the power cable and move
the projector right away*

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
11-11/16˝ (297 mm)
2-9/16˝
(65 mm)
8-1/4˝
(210 mm)
2-9/16˝ high. It slips easily into a bag or briefcase. 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 notebook PC as well. Convenient size and weight are
just two reasons why the PT-LB20U is the logical
choice for mobile presentations.

N O TES ON USE
• The projector uses a high-voltage mercur y 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 during 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.
