Panasonic unveils two cost-efficient LCD projector series today at ISE 2020, comprising six PT-LB426 Series portable and four PT-TW381R Series short-throw LCD projector models. The new series update existing lines with higher contrast images and wider connectivity options, and are due to ship in April 2020.

Both series deliver brilliantly clear images in well-lit classrooms and meeting spaces with virtually no maintenance required during their lifetime. Easy to carry, with intuitive operation and set-up flexibility, these new projectors ensure that all staff can easily benefit from convenient, high-quality visuals.

“These practical updates and operational cost-savings represent a win-win for businesses, educational institutions, and their staff,” said Hartmut Kulessa, European Marketing Manager at Panasonic Business. “Presenters can deliver professional images with point-and-shoot convenience, while administrators enjoy high reliability and less maintenance. These products demonstrate Panasonic’s commitment to providing world-beating A/V solutions at all levels of the market, from the largest global events to the smallest meeting rooms and classrooms.”

Natural Image Quality in Artificial Light

With the update all models have a 25% higher contrast than their predecessors to ensure image quality in well-lit environments. High 20,000:1 contrast is reinforced by up to 4,100 lm[1] (XGA) brightness and detailed HD image reproduction (WXGA models). Panasonic’s Daylight View Lite automatically senses ambient light and optimises projection for comfortable viewing where images would otherwise wash out.

Low Maintenance and Long Life

Both series push Total Cost of Ownership to negligible levels. An original low-degradation lamp lasts 20,000 hours[2] in ECO Mode (10,000 hours*4 at full brightness), while filter replacement is recommended at 10,000 hours[3]. Replacement takes moments via a side-panel door that’s accessible when the projectors are ceiling-mounted. Using these units reduces consumable part inventories, saving money, while Multi Monitoring & Control Software with Early Warning Functions[4] (available on network models) can send alerts before a problem arises, resulting in fewer emergency callouts and less unscheduled downtime.

Flexible Installation, Easy Operation

These flexible projectors are easy to set up on a table or from the ceiling. All models (excluding the PT-LB306) have dual HDMI® inputs and dual D-sub computer inputs[5], while network models gain a 5 V/2 A USB outlet[6] to support media streaming sticks or optional AJ-WM50[7] modules for wireless screen-mirroring from PC or mobile.

The TW381R’s interactive capabilities expand with Whiteboard Software for PC, which supports on-screen notation and the ability to save work as an image file for later distribution. The TW381R Series can project an 80-inch image from a distance of 80 cm or less[8] without screen shadowing. PJLink™ and PC browser control are also available on network models.

The LB426 Series includes a 1.2x zoom lens for freedom of installation; expanded V/H Keystone Correction[9] (H: ±35 °, V: ±35 °); and Curved Screen Correction for distortion-free projection (excluding the LB306). A built-in 10 W[10] speaker, mic input, and audio pin-out are designed in a self-contained media presentation package that’s easy to carry from room to room.

The PT-LB426 Series and PT-TW381R Series are available from April 2020. For more information, please visit Booth 1-H20, Hall 1, ISE2020, Amsterdam RAI, February 11–14, or visit  or
