Daylight View Technology

any people want to use
special colours and designs

but

M

in their presentations,

these colours change when
they’re projected onto the screen in a
lighted room. So they just use plain,
basic colours. As a result, the presenta­tion is visually boring and looks just
like their competitor’s.

Panasonic solves

this problem with

-LB20 Series

our PT
projectors featuring
innovative Daylight
View technology.
These projectors
greatly improve image
performance in brightly
lit places. In fact, the
2,000-lumen brightness
of the PT-LB20 Series
achieves a level of
image performance that
equals many 3,000-lumen
projectors.

Starting with the

the one that best matches your
presentation needs.

Image Performance Rivalling
3,000-Lumen Projectors

Daylight View technology significantly improves
image performance. Our new 2,000-lumen
projectors have attained a level of image per­formance that equals
or exceeds that of our
previous 3,000-lumen
models in brightly lit
environments.*

Vivid Colours in a Bright Room

Panasonic’s unique Daylight View technology
greatly improves colour perception in bright
rooms. Pale colours are divided into six basic
colour 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

projected images.

Auto Operation with

Ambient Light Sensor

The top panel of the unit is

equipped with an ambient

light sensor (

detects changes in the

ambient light intensity and

optimises colour compensa-

tion in f

Daylight View mode also

provides white balance

adjustment settings for

both fluorescent and

incandescent lamps to

Wireless Manager Mobile
Edition 2, an original a pplication

or wireless presentations,
is supplied. This software makes it easy to use
a variety of wireless functions. In Motion
Streaming mode, moving-ima ge files*4can be
sent completel

y wireless, together with audio,
from the hard disk of a PC. There’s no need
to connect an external video source. Just set
up the PC somewhere in the room and imme­diately start into an effective presentation
using both moving images and sound.

Extended Index Style:
16 Thumbnails

This style projects images
from up to sixteen PCs as
small windows. Using the
projector’s remote control,
you can select any one of
the index windows and
display it on the main win­dow or on a full screen.

High-Speed Data Transfer

The IEEE 802.11b/g-compliant wireless LAN
function enables high-speed data transfer.*
Live mode and Multi Live mode, the content of
the PC screen is projected with the same

smooth image motion as you get with

a wired connection. The motion

also flows naturally in

PowerPoint animations.

Plus, the function com-

bines with an original

algorithm
to make mov­ing pictures in
Motion Streaming mode
extremely smooth too.

Flexible 16-Window Index Style

In Multi Live mode, a single projector unit can
receive data from multiple PCs and display
their images simultaneously on its multi­window screen. The projection style can be
selected from Four Window, Index and
Extended Index. It is also possible to send
images from a single PC to multiple
projector units.*

Compact Notebook-Size Body

PT-LB20 models are 297 mm wide by
210 mm deep—about the size of an A4
sheet of paper—and only 65 mm high. Each
slips easily into a bag or briefcase. The

297 mm (11-11/16˝)

compact size makes these models highly
mobile and minimises the space required for

Ultra-Lightweight: 2.1 kg (4.6 lbs)

the PT-LB20 series is the logical choice for
mobile presentations.

N OTES 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 pla te, 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.

• Interruptions may occur in the wireless connection due to signal
interference or PC conditions.
