After a projector has been used for some time, dust particles that have entered the interior accumulate on the optical components 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 particles, to minimise brightness degradation. 

Daylight View 4 measures 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.

The ecological design of the LB90 Series greatly reduces its environmental impact. In Eco Standby mode, power consumption is only 0.9 W^*1. 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 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 preset time. The LB90 Series also complies with the standards of the RoHS Directive^*4. 

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 Windows® and Macintosh, and can be used with a wide range of computers. Wireless Manager ME 5.5 operation can be controlled 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. 

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 available 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.  

• The compact, lightweight body (approximately 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.

• Versatile interfaces: Interfaces include two computer (RGB) inputs, a wired LAN terminal^*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 system^*12 through the projector. 
• The lamp can be easily replaced from the rear panel without 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.
