English
A classroom puts more wear on a display than almost any other room. It runs six to eight hours a day, students write on it constantly, and it has to stay sharp from the front row to the back. If you are shopping for an interactive panel board for classroom use, the specs that matter are not the same ones you would check for a meeting room. For a broader look at the buying decision that applies to both, see our complete interactive panel board buying guide.
What Size Works in a Classroom?
Size comes first because it is hard to change later. The rule of thumb is simple: the farther the back row sits, the larger the panel needs to be.
For a classroom of 20 to 30 students, 65 to 86 inches is the common range. A 65-inch panel works in a standard room where the back row is about 6 meters from the board. An 86-inch panel is the better choice for a larger room or a lecture-style setup where students sit farther back. If the class is small or the room is tight, 55 inches is enough, but most schools settle on 65 to 75 inches.
A 4K resolution (3840 × 2160) matters more in a classroom than in a meeting room. Students are often standing close to the screen, and a lower-resolution panel looks soft up close.
The Specs That Matter Most in a Classroom
Touch. A classroom panel needs 40-point infrared touch. That is the difference between one student writing at a time and several students solving a problem together at the board. Look for a response time under 10 ms and accuracy within 1 mm, so handwriting stays natural instead of lagging behind the pen.
Durability. The glass takes real abuse in a classroom. Anti-glare, scratch-resistant tempered glass with MOHS 7 hardness holds up to pens, erasers, and the occasional knock. It also cuts glare from ceiling lights and windows, which keeps the screen readable from every seat.
Brightness. 350 cd/m² is the practical standard for indoor classrooms. Combined with anti-glare glass, it keeps the board readable even with the lights on and blinds open. If your room gets strong direct sunlight all day, placement matters more than raw brightness.
System and software. Most classroom panels run Android built in, with an optional OPS slot for Windows 11 Pro. The Android side handles annotation and screen sharing. Built-in teaching software saves teachers from juggling extra apps between lessons. Check that the panel comes with the teaching tools your staff will actually use.
Budget: Where the Price Really Comes From
Two panels can list the same specs and differ sharply in price, and the gap usually comes from two places. The first is the panel inside. Reputable manufacturers name the supplier, usually BOE or CSOT; sellers who only write "4K" often use lower-grade screens. The second is the middleman. Buying factory-direct removes the distributor markup, which on a classroom order of several units adds up fast.
We manufacture classroom panels in-house at Lonton. The factory covers over 100,000 square meters with 15 production lines and a 23,000 square meter Class 10,000 cleanroom. Panels come from BOE and CSOT, and a 55-person R&D team handles the touch tuning and firmware. The result is a 98% first-pass yield and a 99.95% quality pass rate, backed by ISO 9001, ISO 14001, ISO 45001, CE, FCC, and RoHS.
Our boards already run in classrooms for Shenzhen University and Lexue Education, and we have built displays since 2005. We support OEM and ODM, so school districts that want their own logo and boot screen get that as standard. Small trial orders start at MOQ 5 units, lead time runs 15 to 25 days, and every panel carries a 2-year warranty.

FAQ
What size interactive panel board do I need for a classroom?
For 20 to 30 students, 65 to 86 inches is standard. A 65-inch panel suits a back row about 6 meters away; go 86 inches for larger rooms or lecture layouts.
Can more than one student write on the board at once?
Yes. 40-point infrared touch lets several students write at the same time, which is useful for group work and problem-solving.
Does a classroom panel need a computer?
No. It runs Android on its own. You only need a computer (via the OPS slot) if your teachers rely on Windows desktop apps.
How durable is the screen?
With anti-glare, scratch-resistant tempered glass at MOHS 7 hardness, the screen withstands daily classroom use for years.
How long does a classroom panel last?
A well-built panel with a reputable panel supplier typically lasts 5 to 7 years in daily classroom use.
