75 Inch Interactive Flat Panel Display
A 4K UHD 75-inch interactive flat panel with 20-point infrared touch, Android 13 and a standard OPS slot — the size most education tenders specify for a standard classroom. Built for system integrators: full specifications published, OEM from 10 units, sample shipped in 3 business days.
The standard classroom size
The T-IFP-75 is a 4K UHD 75-inch interactive flat panel — the size most education projects standardise on for a standard classroom of roughly 30 to 40 students. It is large enough to stay legible from the back row without the cost, weight and wall space of an 86-inch or larger display. Tender documents describe the same product in several ways: interactive flat panel display, interactive panel board, interactive display or simply a smart screen. They are all this category.
It pairs a 20-point infrared touch surface with Android 13, anti-glare tempered safety glass as standard, and a standard OPS slot for optional Windows. For system integrators it slots straight into a Tralltech classroom design: add a T-CPU OPS module for Windows, an active speaker for full-room audio, and a wall mount or mobile stand matched to the wall construction.

How an interactive panel is usually specified
An interactive display gets described through the same set of parameters wherever the document comes from, in roughly the same order. This is that list with the standard T-IFP-75 value against each one, so you can match it against whatever schedule you are working from. It is a reference for whoever has to put the panel on paper — not a claim about any particular document.
| Parameter | Standard build | What to watch when you write the line |
|---|---|---|
| Screen size | 75" | 86", 98" and 110" in the same series. Size follows viewing distance, not floor area. |
| Resolution and refresh | 3840 × 2160 at 60 Hz | State the refresh rate as well. A 4K panel limited to 30 Hz is a different product. |
| Brightness | 350 cd/m² | Standard for a classroom panel behind anti-glare glass. A requirement above this needs a custom build — ask us before quoting. |
| Contrast ratio | 5000:1 | Comfortably above what is normally asked for. |
| Viewing angle | 178° / 178° | — |
| Surface glass | Anti-glare tempered safety glass, standard | Hardness rating supplied on request. Safety glass is often a separate clause from anti-glare — we meet both. |
| Simultaneous touch points | 20 | Infrared, built-in rather than an overlay frame. Overlay frames are sometimes excluded by name. |
| Touch accuracy | ±1 mm across 90%+ of the area | Accuracy is usually written without stating over how much of the surface. Ours is stated. |
| Touch response time | ≤ 15 ms | See the note below. |
| Operating system | Android 13 | Google EDLA licensing is available. It is a clause worth including — it is hard to fake and not every supplier has it. |
| Slot-in PC | Standard OPS slot; T-CPU-i5 / i7, Windows 10/11 | Specify the OPS slot separately from the module. The slot is standard; the module is an option. |
| Built-in software | Whiteboard, annotation, screen recording, split screen, wireless share | — |
| Ports | HDMI 2.1, USB-A, USB-C, RJ-45, dual-band Wi-Fi — see the Ports tab | Front-accessible ports are worth naming as their own line; a teacher cannot reach the rear panel of a wall-mounted display. |
| Control interface | RS-232 | Needed wherever a room control system is in the same package. |
| Built-in speakers | 2 × 10 W front-firing | See the note below. |
| External audio output | Line-level + SPDIF | This is the line that decides room coverage, not the built-in speaker wattage. See engineering note 2 above. |
| Mounting pitch (VESA) | 600 × 400 mm | See the note below. |
| Mains supply | 190–260 V, 50/60 Hz | See the note below. |
| Power consumption | ≈ 288 W typical, standby ≤ 0.5 W | Write the real figure. On generator or solar sites the evaluator is adding up the whole room. |
| Operating temperature | -10 °C to 55 °C | Wide enough for unconditioned classrooms in hot climates. |
| Panel lifespan | ≥ 50,000 hours | — |
| Warranty | 2 years from shipment date | Where a bidder must transfer the manufacturer's warranty, we issue it directly. |
| Certifications | CE · FCC · RoHS | Certificates issued on request for inclusion in a bid. |
| Bidder qualification | Manufacturer authorisation and factory inspection both available | We manufacture the panel rather than resell it, so authorisation letters come from us and the factory can be inspected. |
Four lines where the standard build needs a decision
None of these stop the panel being specified. All four cost money or time if they are found after the order rather than before it.
Send us the actual schedule and we return a completed compliance table, a room wiring diagram and a bill of materials, usually within 24 hours. Where a schedule reads equivalent or superior, that is the clause that lets a compliant panel be offered against a specification written around one supplier's data sheet.
Build the full room around the T-IFP-75
A panel on its own is not a classroom. These are the lines that normally sit alongside it in a bill of materials.

Explore Conference Room →Frequently asked questions
Q.What size interactive flat panel is best for a standard classroom?
A 75-inch panel suits a standard classroom of roughly 30 to 40 students, where the back row sits within about 8 metres of the screen. The rule that decides it is viewing distance, not floor area: for detailed content the furthest viewer should be no more than about four times the image height away. Step up to 86 inches or larger when the room is deeper than that.
Q.Does the T-IFP-75 include a built-in camera?
The camera is a factory option on the T-IFP-75 — either none, or a 48MP AI camera — and it is chosen at time of order. It cannot be fitted after the panel ships, so the choice has to be made on the purchase order. If no camera is specified, budget a T-VID-CAM PTZ camera and a T-AUD-SPK conference speaker in the same bill of materials. The 110-inch panel is the model that carries a camera and microphone array as standard.
Q.Can a 75 inch interactive flat panel run both Windows and Android?
The T-IFP-75 runs Android 13 built in, and accepts an optional T-CPU-i5 or T-CPU-i7 OPS module that adds Windows 10/11. Touch passes between the two systems, so a teacher can switch from the Android whiteboard to a full Windows desktop without rewiring.
Q.What audio output does an interactive flat panel use?
The T-IFP-75 has two 10 W front-firing speakers for near-field sound, plus a line-level audio output. For full-room volume the line-level output must be connected to an active speaker or an amplifier — never directly to a passive speaker. Built-in panel speakers are not how a classroom gets even coverage, whatever wattage a specification quotes for them.
Q.How do I write the T-IFP-75 into a tender specification?
Use the specification table above: it lists the parameters education and donor-funded tenders normally ask for, with the corresponding T-IFP-75 value. The lines that are hardest for a weaker bidder to match are line-level audio architecture with a stated amplifier output, Google EDLA licensing on the Android system, whether the camera is built in or external, and a requirement that the bidder supply a room wiring diagram and full bill of materials rather than a display price alone.
Q.What if the tender specifies something the standard panel does not meet?
Talk to us. We manufacture the panel rather than resell it, so a custom build is usually possible — touch response, speaker output, port layout and the software interface are all build decisions rather than fixed limits. Every project is different, so send us the specification line and we will tell you whether it can be done and what it changes.
Q.Can a 75 inch interactive flat panel be supplied under our own brand?
Yes. OEM customisation on the T-IFP-75 starts from 10 units, including a custom logo, boot screen and launcher interface, with a sample shipped within 3 business days. Because we manufacture the panel ourselves we can also issue manufacturer authorisation letters and accept factory inspection, both of which appear as bidder qualification requirements in donor-funded tenders.
Q.What certifications and warranty does the interactive flat panel carry?
The T-IFP-75 is CE, FCC and RoHS certified and carries a 2-year warranty from the shipment date, with manufacturing defects covered by a free replacement. Certificates are issued on request for inclusion in a bid, and every unit passes a three-stage factory quality control process.
