Interactive Flat Panel for Classrooms: Sizes and What to Check
Short answer: an interactive flat panel (IFP or IFPD) is a large touch screen with a built-in computer that replaces the blackboard and projector: teachers write, annotate, play videos and save lessons on it. Choose the size by the distance to the last row (a 55 inch panel suits rooms where the farthest student sits within about 4 metres), then check touch points, the built-in Android version and memory, brightness, a commercial 24x7 panel and the warranty. Our 55 inch T291194-A IFPD costs ₹1,27,050 with a wall mount and 3-year onsite warranty. Prices include GST and delivery across India is free.
What is an interactive flat panel and how is it different from a projector?
A projector throws a picture onto a wall or screen. It needs a dark room, the bulb dims with age, and the teacher's shadow falls on the picture. An interactive flat panel is a bright LED screen with a touch layer and an Android computer built in, so it works with the lights on and the windows open, and the teacher writes directly on the glass with a finger or stylus.
It is also different from touch digital signage. Signage is built to play ads and notices for passers-by. An IFP is built for writing and teaching: more touch points, more memory, a whiteboard app and a panel rated for long school days.
What size interactive panel do I need for a classroom?
The size that matters is the distance from the screen to the farthest student. A common rule used in classroom audio-visual planning is that for reading text and detail, the farthest viewer should sit no more than about six times the screen's height away. For a 16:9 panel, the height is roughly half the diagonal. That gives:
| Panel size | Screen height (approx.) | Farthest seat for reading text (approx.) | Typical room |
|---|---|---|---|
| 55 inch | 69 cm | 4.1 m | Tuition room, small classroom, meeting room |
| 65 inch | 81 cm | 4.9 m | Standard classroom of 30 to 35 |
| 75 inch | 93 cm | 5.6 m | Larger classroom |
| 86 inch | 107 cm | 6.4 m | Large classroom, seminar room |
These are planning figures, not limits. Students further back can still see videos and pictures; it is small handwriting that becomes hard to read. Measure your room before you buy. Our current stock is the 55 inch model; for a bigger room, send us your room length on WhatsApp and we will advise.
What should I check before buying an interactive flat panel?
- Touch points. This is how many fingers or pens the screen tracks at once. With 20-point touch, several students can write or solve problems on the board together.
- Built-in computer. Look at the Android version, RAM and storage. Newer Android and more memory mean whiteboard apps, browsers and videos run without lag, and lessons can be saved on the panel. The T291194-A has Android 14, 8GB RAM and 128GB storage.
- Resolution. 4K UHD keeps text sharp when students sit close, especially on larger panels.
- Brightness. Classrooms are bright. A panel around 400 nits is comfortable in a normally lit room; avoid placing it opposite an open window or direct sunlight.
- Zero bonding. In a zero-bonded panel the touch glass and the display sit with no air gap between them. The ink appears right under the pen tip instead of slightly off to one side, which makes writing feel natural, and the picture shows less reflection.
- 24x7 commercial panel. A school runs the screen for six to eight hours a day. A commercial panel rated for continuous use lasts far longer than a home TV with a touch frame added.
- Warranty and service. Onsite warranty means a technician comes to the school rather than the school shipping a heavy panel. The T291194-A carries a 3-year onsite warranty.
- Mounting and ports. Check what stand or bracket is included (the T291194-A includes a wall mount) and confirm the ports you need, such as HDMI for a laptop or a slot for an OPS computer, on the product page or with us.
Where and how should I install it?
- Wall position: the front wall, centred, with no window directly behind the students' line of sight to the screen.
- Height: mount it so the teacher and students can reach at least the lower two-thirds of the screen comfortably. For young children, keep the bottom edge lower.
- Power: give it a dedicated socket on the inverter line so a power cut does not interrupt a lesson.
- Network: a LAN point or good Wi-Fi near the panel helps with online content and updates.
- Laptop at a distance: if the teacher's laptop sits away from the panel, an HDMI extender can carry the picture over a LAN cable; see video baluns and HDMI extenders.

FAQ
What is the price of an interactive flat panel for a classroom?
Our 55 inch T291194-A interactive flat panel costs ₹1,27,050 including GST, with a wall mount and 3-year onsite warranty, and free delivery across India.
Which size interactive panel is best for a classroom?
Size by the distance to the last row. As a planning rule, a 55 inch panel suits rooms where the farthest student is within about 4 metres; bigger rooms need 65 to 86 inch panels.
Does an interactive flat panel need a computer?
No. All-in-one panels such as the T291194-A have a built-in Android 14 computer with 8GB RAM and 128GB storage, so they work on their own. You can still connect a laptop if you prefer.
Is an interactive panel better than a projector?
For most classrooms, yes. A panel is bright enough to use with the lights on, has no bulb to replace, casts no shadow and lets the teacher write directly on the screen.
What does 20-point touch mean?
The screen can track 20 touch points at the same time, so several students can write or draw on it together.
Can an interactive flat panel run all day?
The T291194-A uses a commercial-grade panel rated for 24x7 operation, which suits a full school day of use.
