							Bright, Easy-to-Use, Dust-Resistant 
Portable Projectors
The Panasonic LB90 Series is designed for people who want 
a projector with excellent basic performance and ease of use — in 
both portable and ceiling-mounted applications. This versatile series 
ensures solid performance with a  dust-resistant structure, which 
minimizes any dust-related image degradation, and a low standby 
power consumption of 0.9 W*
1 to reduce environmental impact. 
The PT-LB90NTU also features a  network function that allows 
wireless/wired LAN con gurations. Connecting the projector to 
a wireless LAN system further boosts the layout  exibility during 
presentations.  Wired LAN connection enables remote operation, which is 
especially  ideal for ceiling-mounted use. 
Multi Projector Monitoring and Control Software, which lets 
you monitor and control several Panasonic projectors from a single 
computer, is also available.  The compact body of the LB90 Series is  lled with Panasonic 
projector technologies to meet needs of many kinds.

Dust-Resistant Structure Minimizes 
Image Degradation
After a projector has been used for some 
time, dust particles that have entered the 
interior accumulate on the optical compo-
nents and lower their performance. The 
LB90 Series prevents this with a unique 
dust-resistant structure. The LB90 Series 
has touch-sensor controls that eliminate 
the gaps around conventional buttons, and 
a lens cover. The design also incorporates 
a cover that protects the zoom/focus ring 
when not in use. These features combine 
to help reduce dust entry. And they all work 
together with the high-performance Micro 
Cut Filter, which effectively traps dust parti-
cles, to minimize brightness degradation. 
Daylight View 4 Offers Clear, Crisp 
Images Even in Bright Surroundings*2
Daylight View 4 meas-
ures the surrounding 
illumination with a 
built-in ambient light sensor, and corrects 
the image in real-time to project clear, 
crisp images even in brightly lit rooms. It 
improves perceived sharpness, brightness 
and contrast, and projects lifelike images 
with remarkable depth. 
Low Standby Power Consumption of 
0.9 W*1
The ecological design of the LB90 Series 
greatly reduces its environmental impact. In 
Eco Standby mode, power consumption is 
only 0.9 W
*2. This reduction brings standby 
power consumption down to about 1/3 the 
level of previous Panasonic models
*3. As 
examples of other environmental design 
features, no styrofoam is used in packing 
materials, no halogenated flame retardants 
are used in the cabinet, lead-free glass is 
used for the lens, and an Auto Off Timer 
switches the projector to Standby mode 
when no input signal is received for a pre-
set time. The LB90 Series also complies 
with the standards of the RoHS Directive
*4.

*2  There is no actual change in the rated brightness or contrast ratio. 
*3  Reduced from 3 W in the PT-LB80NTU to 0.9 W in the PT-LB90NTU.
*4  Restriction of the use of certain Hazardous Substances. The specified toxic substances used in the electrical and electronic equipment that is manufactured and distributed within Europe are controlled (the 
six substances are lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl esters (PBDE)), and all Panasonic projectors comply with the standards of 
the European RoHS Directive.

							Quick and Easy Set-Up for Flexible 
Presentations
The Wireless Manager ME5.5 application 
that is included with the projector makes it
 
easy to send and display a computer screen 
when the PC and projector are connected to 
a wired or wireless *
5 LAN system. You can 
also send audio*6 and video*7 files. The 
application is compatible with both Win-
dows
® and Macintosh, and can be used 
with a wide range of computers. Wireless 
Manager ME 5.5 operation can be con-
trolled with the launcher that is displayed 
on the PC screen. Its graphic display further 
simplifies operation. When connected to a 
wireless LAN *
5 system, you don’t need to 
connect a VGA cable to the PC, so set-up is 
quick and easy, and the layout is highly 
flexible. You can also project several PC 
screens, so meetings with a large number 
of participants can proceed smoothly.
  Multi-Live Mode
You can simultaneously display up to 16 
computer screens, opening the door to a 
variety of new projector applications.
 Projector Signal Map (S-MAP)
The Projector Signal Map graphically dis-
plays all of the presently connectable pro-
jectors in three levels that indicate the 
strength of the wireless signals between the 
projectors and your computer. This lets you 
easily search for the projectors you want 
even when wireless projectors are being 
used in adjacent conference rooms or 
classrooms.  Easy Remote Operation
A Web browser on a computer connected 
through a wireless*
5 or wired LAN system 
lets you remotely operate projectors and 
check their status. An e-mail messaging 
function can also notify you when a lamp 
needs replacement, and indicate the overall 
projector status. In addition, Multi Projector 
Monitoring and Control Software *
8 is avail-
able for monitoring and controlling multiple 
Panasonic projectors from a single PC. The 
wired LAN terminal is compatible with 
PJLink™(Class1), an open protocol that is 
used by many manufacturers, to enable 
integrated control of systems that contain 
different brands of projectors.

							Convenient and Easy Functions for 
Portable Use
 The compact, lightweight body (approxi-
mately 2.96 kg (6.5 lbs)) makes it easy to 
move the projector from one classroom or 
conference room to another.
  With Speed Start, the image appears in 
about three seconds*9 after you press the 
power button.
  Auto Setup automatically corrects the 
image position, dot clock and clock phase 
when the projector’s input signal changes.
  Auto Signal Search automatically detects 
what kind of source is connected and 
begins projection.*
10
  With Real-Time Keystone Correction, the 
projector automatically senses if you 
adjust its angle (in the vertical direction) 
during operation and instantly makes 
whatever keystone correction is necessary 
for optimal viewing.
  Whiteboard and 
Blackboard modes 
are convenient when 
projecting in rooms 
that don’t have a 
screen.
  Direct Power Off uses accumulated power 
to keep the cooling fan operating until the 
lamp is cooled, so you can disconnect the 
power cable immediately after use.
  A soft carrying 
case with shoulder 
belt is supplied.
Convenient Functions for 
Ceiling-Mounted Use
  Versatile interfaces: Interfaces include two 
computer (RGB) inputs, a wired LAN ter-
minal*
11, and a serial (RS-232C) terminal 
for external control. The serial terminal 
has an emulator function that lets you 
continue using existing control systems 
when replacing a previous Panasonic 
model. It is also possible to output audio 
during Standby mode. This is convenient 
when connecting an external audio sys-
tem *
12 through the projector.
 The lamp can be 
easily replaced from 
the  rear panel with-
out having to remove 
the projector from 
the ceiling mount 
bracket.
  Direct Power Off lets you turn off the 
room’s main power switch without turning 
off the projector individually, so you can 
leave the room right after a meeting ends.
Effective Theft Prevention with the 
Startup Logo
You can change the default Panasonic start 
up logo to any logo you want.
  A new logo  
can be easily uploaded by connecting a 
computer to the LB90 Series through the 
LAN *
13 or serial connection by using the  
Logo Transfer Software*14. An abundance of 
other security measures are also included, 
such as a security anchor, a user password, 
a control panel lock,   and text superimposing. 
Quiet, 29dB*
15 Silent Design
This helps maintain people’s attention on 
the discussion taking place or the screen
  
image during quiet scenes. Easy-to-Use Remote Control
The large buttons and long 
operating range of the wireless

 
remote control make it easy to 
use. During Wireless Live 
mode on the PT-LB90NTU, you 
can also shift between Micro-
soft
® PowerPoint® pages by

NOTES ON USE The projector uses a high-volt-
age mercury lamp that contains 
high internal pressure. This 
lamp may break, emitting a 
large sound, or fail to illumi-
nate, due to impact or extend-
ed 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 projector includes consum-
able parts. The frequency of 
replacement for the lamp and 
other consumable parts will 
increase if the projector is sub-
jected to extended, continuous 
use. For details, please consult 
a service representative.Project size
