English
People call these things by a lot of names. Interactive panel, interactive board, smart board, digital whiteboard. If you searched for "interactive panel board," you are looking for the same device: a large touchscreen you can write on, present from, and use for video calls, without needing a projector or a separate computer.
Schools put them in classrooms. Offices put them in meeting rooms. The hardware is basically the same. What changes is which specs you should care about.
What Is an Interactive Panel Board?
An interactive panel board is an all-in-one touchscreen display, usually 55 to 110 inches, that runs its own operating system. You turn it on and start writing with your finger or a stylus. You can share a laptop screen to it wirelessly, run video calls on it, and install apps directly on the device.
The key word is all-in-one. A projector needs a bulb, a screen, a computer, and cables. An interactive panel board replaces all of that with a single device. That is why schools and companies have been switching over for the past few years.
If you want a quick overview of the basics before we get into specs, we also have a plain-English guide on what an interactive panel board is and how to choose one.
The Specs That Actually Matter
Most spec sheets look the same, so it helps to know which numbers change how the device feels in daily use.
Touch. The standard today is infrared (IR) touch with 40 simultaneous touch points. That means two students can write at the same time during a lesson, or several people can annotate a document in a meeting. Look for a response time under 10 ms and accuracy within 1 mm. If you plan to wear gloves or use a stylus, IR handles both with no calibration.
Brightness. 350 cd/m² is the realistic standard for indoor use. Some sellers quote higher numbers that do not hold up in a bright room. For a classroom or a meeting room with windows, 350 cd/m² with anti-glare glass is enough. If the panel faces direct sunlight all day, you need to think about placement, not just brightness.
Resolution. 4K UHD (3840 × 2160) is the baseline for anything 65 inches and up. At that size, a 1080p panel looks soft when you are standing close to it, which is exactly what happens in a classroom.
System. Most panels run Android built in, with an optional OPS slot for a Windows 11 Pro module. The Android side handles quick annotation and screen sharing. The OPS slot lets you drop in a full Windows PC when you need desktop apps. Check whether the model offers this slot before you commit, because it is the difference between a display and a full computer.
Camera and audio. Built-in speakers (2 × 15W is common) cover a normal room. If you run hybrid meetings, look for a model with a built-in camera and microphone array, or budget for a separate one.
Classroom vs Meeting Room: What Changes
The same panel works in both places, but the priorities shift.
In a classroom, teachers care about writing feel and durability. The screen takes pens, erasers, and the occasional knock. Anti-glare, scratch-resistant glass (MOHS 7 hardness) matters. Multiple students writing at once needs 40-point touch. Built-in teaching software saves a teacher from juggling extra apps.
In a meeting room, the priorities are screen sharing and video calls. Wireless casting from a laptop or phone, a fast USB-C port with power delivery, and a camera for hybrid meetings matter more than the whiteboard app. The panel spends more time displaying a deck than it does being written on.
What to Look For in a Supplier
This is where the price differences between vendors actually come from. A panel can look identical on a spec sheet and feel very different in a classroom a year later.
Two things to check before you order. First, the panel inside. Reputable manufacturers name the panel supplier, usually BOE or CSOT. Sellers who only say "4K" and skip the brand are often using lower-grade screens. Second, the factory behind the product. A manufacturer with its own production lines and cleanroom can control quality in a way a trading company cannot.
We manufacture interactive panels in-house at Lonton. The factory covers over 100,000 square meters with 15 production lines, including a 23,000 square meter Class 10,000 cleanroom. Panels come from BOE and CSOT. A 55-person R&D team handles the firmware and touch tuning. The result is a first-pass yield of 98% and a 99.95% quality pass rate, backed by ISO 9001, ISO 14001, and ISO 45001 plus CE, FCC, and RoHS.
The company has been building displays since 2005. Our panels run in classrooms and meeting rooms for clients like China Mobile, China Unicom, T-Mobile, Shenzhen University, and Lexue Education. We support OEM and ODM, so if you want your own logo, boot screen, and packaging, that is standard for us, not an extra service.

FAQ
Is an interactive panel board the same as a smart board?
Yes, in most cases. "Smart board" is a brand name that became generic, like Kleenex. An interactive panel board is the same category of all-in-one touchscreen display.
What size interactive panel board do I need?
For a classroom of 20 to 30 students, 65 to 86 inches is the common range. For a small meeting room, 55 to 65 inches works. For a large boardroom, 86 inches and up.
Does an interactive panel board need a computer?
No. It runs Android on its own. You only need a computer (via the OPS slot) if you rely on Windows desktop apps.
Can two people write on an interactive panel board at the same time?
Yes, with 40-point infrared touch. Multiple students or colleagues can annotate at once without interference.
How long does an interactive panel board last?
A well-built panel with a reputable panel supplier typically lasts 5 to 7 years in daily classroom use. The backlight and touch frame are the parts that matter most.
