Interactive Display Boards for Classrooms & Meeting Rooms
A 4K touchscreen, a whiteboard and a computer in one wall-mounted panel. Teachers write on it, annotate over anything, and record the lesson; meeting rooms share screens to it wirelessly. Supplied and installed, with the mount and training included.

An interactive display board — the trade calls it an interactive flat panel — replaces the projector, the whiteboard and the classroom PC in one panel. It is the same purchase decision whether the room is a classroom, a coaching hall or a boardroom: size for the room, touch that keeps up with writing, and software the people in the room will actually use.
The two ranges we supply
We quote against two lines: LG CreateBoard, which reaches down to 55 inches and adds remote fleet management and the security controls a shared room needs, and LOGIC INFINITY, an Indian-market line with the loudest built-in sound of the two and a specified Core i5 Windows module. Both are 4K on every size, both take up to 40 touch points, and both accept a slot-in OPS PC, so the choice is about the room and the IT department rather than about picture quality.

Which size for which room
| Size | Room | Rule of thumb |
|---|---|---|
| 55" | Huddle rooms, staff rooms, small labs | Only where 65 will not fit — text gets hard past the fifth row |
| 65" | Classrooms to about 40 students | Readable to roughly 8 m — most school classrooms |
| 75" | Large classrooms, training halls | The most common choice for coaching institutes |
| 86" | Auditoriums, boardrooms | Only worth it when the last row is past 10 m |
What to check before buying — any brand
- Touch points that hold up in use: 20 true simultaneous writers is plenty; 40 is headroom
- Android alone, or a slot-in Windows PC module — decide by the software your teachers or team already use
- Anti-glare glass, not glossy: a window behind the class makes a glossy panel unusable
- On-site warranty terms in writing — a classroom panel that leaves for repair is a classroom offline
- Who installs and who trains: a panel nobody was shown how to use becomes a very expensive whiteboard
What it costs
Quoted per unit against size and configuration rather than from a per-square-foot rate. In the current Indian market, entry 65-inch panels start under ₹1 lakh and feature-heavy 86-inch corporate configurations run well past ₹2 lakh — where a specific model lands depends on touch spec, the Windows module, and the service terms behind it. Send us the room size and how it will be used, and we will quote a configuration with the mount, installation and training included.

Common questions
What does an interactive display board cost in India?
Entry 65-inch panels start under ₹1 lakh in the current market; 75-inch classroom configurations typically land between ₹1.2 and ₹1.8 lakh, and large or Windows-equipped corporate panels go higher. We quote per unit with the mount, installation and training included, after understanding the room.
Interactive panel or projector for a classroom?
For a standard classroom, the panel: brighter in daylight, no lamp costs, and writing that keeps up with a teacher. A projector still makes sense where you need an image larger than about 120 inches, such as a hall or auditorium.
Android only, or with Windows?
Android built in covers teaching apps, browsing and whiteboarding. Add the slot-in Windows module when your institution runs Windows-only software — ERP clients, specific exam or CAD tools. It can be added later, so you are not locked in on day one.
Which makes do you supply?
LG CreateBoard (TR3DK series, 55 to 86 inch) and LOGIC INFINITY (AX series, 65 to 86 inch). Both are 4K with up to 40-point touch and both take a slot-in Windows PC module, so most rooms can be quoted either way; we quote the configuration that suits the room rather than pushing one badge.
LG CreateBoard or LOGIC INFINITY — which should I choose?
Choose LG if you need a 55-inch size, if IT wants to manage a fleet of boards remotely, or if the room is shared and you want screen lock, USB lock and scheduled file deletion. Choose INFINITY if built-in sound matters — it carries 2 × 16 W front speakers — or if you want the Windows module specified up front as a Core i5 with 8 GB and a 256 GB SSD. Picture quality is not the deciding factor; both are 4K panels.
Is the board Wi-Fi ready out of the box?
Both connect by wired LAN as standard. On the INFINITY range Wi-Fi comes from an optional wireless module, so say if the room has no network point and we will include it. LG supports wireless screen sharing from phones and laptops on the same network, and Bluetooth for a keyboard, mouse or speaker.
