New LG Interactive Displays Designed for Maximum Versatility in Post-Pandemic Classrooms


As schools reopen for in-person education and hybrid learning, LG Business Solutions has introduced a series of cost-competitive, technology-agnostic interactive displays designed to take teaching and learning to the next level. 

The new LG TR3DJ series is available in 65-, 75- and 86-inch models, helping to ensure students can see what the teacher is presenting—even if still sitting socially distant—and supports virtually any learning management system, cloud drive, or online conferencing platform a school adopts to facilitate in-person or hybrid/remote learning.

“As schools welcome students back into classrooms, many are also in a technology refresh cycle, seeking ways to enable interactive learning without tying their IT departments to any single platform, and doing it in a way that puts the latest tools in the hands of the most students and teachers,” said Victoria Sanville, education account lead at LG Business Solutions USA. 

“These new solutions work with virtually any software they choose, making them ideal replacements for the latest-generation technology. Teachers can display, annotate and share content from a wide variety of sources, while technology managers will appreciate the devices’ plug-and-play ease of deployment,” said Sanville, who also highlighted LG’s role as a champion for social-emotional learning in K-12 schools across America.

All three interactive displays feature IPS display panels for wide viewing angles—critical in classrooms where students may be more spread out than usual—and 4K Ultra HD resolution for presenting detailed content at a large scale. The TR3DJ series’ 20-point, multi-touch surface makes it easy to collaborate on-screen, while the ultra-thin (1 millimeter) gap between the IPS screen and anti-glare, tempered glass screen helps assure highly precise touch and on-screen writing experiences. Each TR3DJ interactive display is available with two stylus pens in differing colors and tip sizes, allowing users to draw or write simultaneously.

The TR3DJ series comes embedded with the Android 8.0 operating system and is compatible with other major operating systems. With its built-in web browser and OPS (Open Pluggable Specification) slot for conveniently adding a computer module, the TR3DJ series displays are designed to support virtually any application, content management system, learning platform or online conferencing solution that a school uses to engage students in-class and remotely.

Each TR3DJ interactive display is WiFi-enabled for easy connectivity out of the box. When teachers and students join the same network, these displays enhance collaboration thanks to built-in software. ScreenShare Pro allows educators to show up to six screens at once, including from any mobile device that supports wireless mirroring, while Air Class supports group features such as polling, interactive Q&As and messaging for up to 30 connected students. The built-in software, plus the ability to annotate virtually all file types, is accessible from an on-screen toolbar. There are even countdown and stopwatch functions for managing class time effectively.

“With these new models, LG now has a full family of classroom products that support a wide variety of pedagogies while remaining budget-friendly for schools trying to do the most for students in challenging times,” Sanville continued. “The interactivity offered by the TR3DJ series is especially important now as students get back to normal and rediscover learning alongside their peers.”

Each TR3DJ display includes two built-in 10-watt speakers for delivering audio content. Embedded Bluetooth allows users to connect wireless peripherals, such as external speakers, keyboards, mice and more. Additional connections include three HDMI ports, one RS-232C port, audio in/out, RJ-45 LAN ports and six USB 2.0/3.0 ports. For enhanced security, the TR3DJ features USB Block Mode to prevent copying data to unauthorized devices.

Every TR3DJ interactive display is backed by a three-year limited warranty, with extended five-year coverage available through select LG dealers serving the education market. For more information about LG’s commercial display portfolio, please visit To download hi-res images, click here.

Dovetailing with the launch of these displays, LG is supporting thousands of schools across the United States with the Life’s Good: Experience Happiness program, which equips youth with skills to better cope with stress and anxiety, build resilience, and support a life-long happiness mindset. This award-winning LG initiative – developed and implemented with experts in social-emotional learning, education and the science of happiness – already has reached more than 4 million students with science-based curriculum teaching sustainable happiness skills.
