75 inch infrared touch frame
A 75 inch frame spans 1.7 m, so we stiffen the extrusion with a reinforced corner block — the frame stays flat across the span instead of bowing in the middle.
FOB Shenzhen, frame only, 1–50 pcs. Add $80 for 3 mm tempered glass. Volume tiers quoted on request.

Inside the 75 inch frame
1686 × 964 mm outside with a 13 mm side bezel and a 19 mm bottom rail. This is the same extrusion profile we run from 32 to 110 inch — the cut length changes, the section does not, so the frame in the photo is what arrives at every size in the range.
- 1686 × 964 mm outer, 1660 × 934 mm active area
- 2–40 touch points, USB HID, no driver for Windows, Android or Linux
- 336 pcs in stock, leaves in 3–7 days
Packing. One frame per cardboard tube with foam ends. Crates start at 98 inch, where a tube stops being practical.
Corner joint. Cast corner block pinned into the extrusion — this is what keeps an 86 inch frame flat instead of bowing in the middle.
What the 75 inch frame fits
The active area is 1660 × 934 mm — a standard 75 inch 16:9 panel. The frame adds 13 mm on three sides and 19 mm at the bottom, which is where the controller PCB and USB cable sit.
- Outer frame: 1686 × 964 mm, 9.5 mm deep
- Housing cut-out: leave 1690 × 968 mm plus 3 mm clearance for the cable
- Glass clearance: up to 5 mm thick; 8 mm with the wide-gap version
- Mounting: front-flush with M3 inserts, or side brackets
Typical builds at this size: lecture hall board, large meeting room, showroom display.
75 inch frame — options and unit price
Indicative FOB Shenzhen prices at 10-point configuration. Higher touch counts add controller cost, not sensor cost, so the jump is smaller than most buyers expect.

What happens after the carton is open
A frame is not finished hardware until it is calibrated against the display it sits on. Three things ship with this size to get you there, and none of them are extras.
No driver, on any system
USB HID digitizer. Windows 10/11, Android, Linux and ChromeOS enumerate it without installing anything. macOS reports single point only — worth knowing before you commit.
Calibration tool and profile
Windows and Linux builds, 4/9/25-point runs, written to the controller so it survives a power cycle. Stuck? A ten-minute remote session with our engineer calibrates it with you.
Installation sheet for this size
Clearance, 0.5 N·m torque, ground under 4 Ω, 3 m passive USB limit — plus the symptom table that covers most first-install problems.

75 inch frame questions
What is the outer size of a 75 inch frame?
Can I get this size with a different bezel?
How many units of the 75 inch frame fit in a carton?
Do you supply the tempered glass with the frame?
Can this be used as a touch overlay on a display I already own?
What to write on the PO so it arrives correctly
In a BOM this line usually reads infrared touch frame kit or IR frame kit, because what ships is not just the aluminium: four extrusions, four corner blocks, one controller, one 1.8 m USB cable and four mounting brackets. The kit wording matters for customs and for your assembly line — a knocked-down frame is a component, not a finished appliance.
The most common build we ship is not a product at all — it is a retrofit. A shop, a school or a factory has a screen, and someone wants to press it. An overlay frame is the cheapest way to get there: no new display, no new mounting, no firmware.
If your enquiry uses a name not listed here, send it anyway — a photo of the old part or the housing opening settles it faster than any glossary. Full terminology list →
