Key Features
- WXGA 1280 x 800
- 3,300 ANSI lumens
- 0.46:1 short throw
- 20,000:1 contrast ratio
- Dual-pen interactive projection
The Panasonic PT-TW381RU Interactive Short throw projector combines 3300 lumens of brightness with WXGA resolution to enhance your presentations. The Panasonic PT-TW381RU has a 0.46 throw ratio which will allow you to project an 85" image from only 3'3" away. Communicate more effectively by making notations on stills, graphics, and documents, adding new information as your meeting or lessons using the supplied Interactive Light Pen or optional Interactive Pointer. Companion LightPen3 Software for Windows or Mac improves writing smoothness for up to two presenters at once with support for high frame-rates. You can save modified images to your PC for distribution later on.
Auto calibration gets you started faster. If preferred, you can also set up manually just by touching four screen corners with the pen/pointer.
Faster refresh-rate lets you write with the smoothness of a real marker.
Dual Pen Mode (half- or full-screen modes) lets two presenters write at the same time.
The screen is divided vertically with individual color and line-width selection available on both panes.
Color and line-width for both pens is the same across the whole screen.
Lightly touch the included pens across the projection surface to write.
Need more functions? The Panasonic PT-TW381RU Interactive capabilities expand with Whiteboard Software for Windows PC. This software works with interactive-ready Panasonic projectors and Touch Screen LCD displays to greatly enhance your communication capabilities.
*1 Download free LightPen3 Software for Windows here or for Mac OS here. Please check the device, OS version, and driver requirements (if needed) before download and installation to your device.
*2 Additional pens/pointers are optionally available to support multiple presenters.
*3 Available for Windows operating systems.
*4 Download free Whiteboard Software for Windows 8.1 and Windows 10 here.
*5 Please note that some functions available to professional displays are not supported on projectors.




Give your presentation team an edge with bright and vivid 3,800 lm* images behind them. Thanks to 20,000:1 contrast—25 % more than our
PT-TW371R Series—graphics, text, and video are clear and sharp while color resists washout in natural or artificial light.
* Brightness is 3,300 lm for the Panasonic PT-TW381R/TW380, 3,200 lumens for the PT-TX350, and 3,800 lumens for the PT-TX440.
Communicate with flair almost anywhere with support for desktop or ceiling installation. The Panasonic PT-TW381R Series can be set up at arm’s length from the screen to reproduce a big 80-inch image*. As well as bringing large pictures to small spaces, the short-throw lens casts the image in front of the presenter so his or her shadow does not obscure the screen.
* Projection distance is 80 cm for the Panasonic PT-TW381R/PT-TW380 and 75 cm for the PT-TX440/PT-TX350 when projecting an 80-inch image.

Daylight View Lite optimizes color and brightness according to ambient lighting levels. This function is easily accessed using the supplied remote control.

A breakthrough in materials design has enabled development of a new low-degradation long-life lamp designed to operate for 20,000 hours* before recommended replacement. Enjoy lower running costs and excellent reliability.
* Lamp life is approximately 20,000 hours in Eco Mode and 10,000 hours in Normal/Quiet Mode. Replacement timing varies depending on operating environment and usage conditions.
Together with an extra-long-life lamp, the Panasonic PT-TW381R Series equips a durable air filter supporting up to 10,000 hours* service before suggested maintenance. The filter can be replaced in moments via a handy panel door even when the projector is mounted on the ceiling.
* Filter life is approximately 5,000 hours in Normal Mode, 6,000 hours in Eco Mode, and 10,000 hours in Quiet Mode. Replacement timing varies depending on operating environment and usage conditions.
Manage up to 2,048 devices via network with system map visualization and auto-search of unregistered devices. The free software is available with Early Warning functions* (free 90-day trial). These enable real-time monitoring, abnormality detection, and much more.

* Early Warning Functions (ET-SWA100 Series) are included free with Multi Monitoring & Control Software Ver. 2.0 and later, but require a paid license key and activation to continue usage after a 90-day trial period.
The PT-TW381R Series can connect up to four players at a time via dual HDMI and D-sub inputs*, so multiple presenters won’t have to share a cable, making transitions smoother.
* Computer In 2 is shared with Computer Out.
Create a collaborative space with our optional USB wireless modules for mobile*2 and PC*3 screen-mirroring, or power a media streaming module*4 via USB DC terminal for media casting from PC or mobiles without cable clutter.
*1 Optional ET-WML100/AJ-WM50 series wireless module is subject to regional availability and requires Wireless Projector app for iOS or Android™ or Presenter Light (for Windows® PC) to enable wireless projection. ET-WML100 Series and AJ-WM50 Series devices are both compatible with all projectors in this series, and either can be used to enable the wireless network function.
*2 When using the Wireless Projector app, display resolution differs depending on your iOS/Android device and the display device. The maximum supported display resolution is WXGA (1280 x 800).
*3 When using Presenter Light Software, images are projected with 1280 x 800 dots or 1024 x 768 dots onto the screen. Also, your PC display resolution may be forcibly changed, and audio playback disrupted or become noisy, while images and sound are being transmitted.
*4 Panasonic cannot guarantee compatibility with third-party media streaming devices.

V/H Keystone Correction (H: ±15 ° auto/manual, V: ±15 ° manual) provides some leeway for image geometry adjustment when projecting off-axis to the screen center, while Curved Screen Correction tames distortion when shooting onto convex or concave surfaces.

Intended for easy room-to-room portability or as an on-ceiling solution supporting Panasonic software and third-party control protocols over LAN, the Panasonic PT-TW381R Series’ light 3.9 kg (8.6 lbs) weight makes handling a breeze. Manual controls let presenters set up quickly and easily on-site and commence their workshop almost immediately with less wasted time.
Choose your preferred mix of high brightness, extended maintenance, or quiet operation. Normal Mode prioritizes picture quality in bright environments, while Quiet Mode projects at a virtually inaudible 30 dB*1 with an extended filter replacement cycle. Eco Mode strikes a useful balance between the two with 20,000-hour*2 lamp-life and 35 dB*1 operation.
*1 38 dB in NORMAL Mode.
*2 Lamp life is approximately 20,000 hours in Eco Mode and approximately 10,000 hours in Normal/Quiet Mode. Replacement timing varies depending on operating environment and usage conditions.
Insert a USB memory device into the USB port and start projecting stored content straight away without need of a connected PC. The USB media player supports a variety of image files, such as JPEG and PNG. Start your presentation right away without having to connect to a computer.
Note: Still images only. Video reproduction is not supported.
Projectors with Direct Power Off function allow you to switch off the projector and unplug the power cord right after use. You can safely turn off the room’s breaker switch without waiting for the projector to cool down. This is useful in applications where the projector is mounted on the ceiling, or in time-critical situations.
