Product Overview

The LG 86TR3DJ-B is an 86-inch 4K UHD interactive touch display for classrooms and meeting rooms. It uses an IPS panel with 330-nit brightness and 20-point infrared multi-touch (up to 10-point writing), with dual pen and dual color support.

Product Description

This interactive display delivers a 3,840 x 2,160 IPS image with 178-degree viewing angles for wide seating. Infrared multi-touch supports up to 20 simultaneous touch points and 10-point writing, while a 1 mm gap to the tempered glass keeps parallax low for precise input. Dual pens allow two colors to be used at once, and annotation works over virtually any input source. Air Class connects up to 30 student devices on the same network with voting, answering, and text-sharing tools. ScreenShare Pro shows up to six shared screens in real time and supports Chromecast and Apple device mirroring across iOS, macOS, Windows, Android, and Chrome OS. The integrated OPS slot accepts an optional PC module, an embedded web browser runs without an external device, and Bluetooth connects speakers, a mouse, or a keyboard. Front-bezel speakers deliver clear audio, and USB Block mode restricts data copying for secure environments.
