Overview
The LG CreateBoard TR3DK is an interactive digital board for classrooms and meeting rooms: a 4K IPS panel behind 9H toughened anti-glare glass, 40-point touch that works with pens or fingers, and Android 13 with Google EDLA certification so Google apps run natively. An OPS slot and USB-C with power delivery bring a Windows PC or laptop onto the same screen, and CreateBoard Share handles wireless sharing from any device.
Fleets are monitored and controlled remotely with LG ConnectedCare, which reports status and pushes settings to every board on the network. Siddhi Global supplies the TR3DK in 55 to 98 inch through its ISMS (Integrated Systems Management Services) partnership, and can still source the earlier TR3DJ and TR3BF boards for schools standardising on an existing model.
