70 inch infrared touch frame
70 inch frames go to lecture rooms and boardrooms where the display is wall-mounted and the frame has to be lifted into place by two people. It ships crated with corner blocks and a lifting strap, because a 70 inch frame is awkward rather than heavy.
FOB Shenzhen, frame only, 1–50 pcs. Add $72 for 3 mm tempered glass. Volume tiers quoted on request.
What is in the 70 inch box
One frame at 1576 × 902 mm, one controller board, a 1.8 m USB cable and four mounting brackets. Glass is separate — add it only if your housing does not already carry a front sheet.
- 1576 × 902 mm outer, 1550 × 872 mm active area
- 2–40 touch points, USB HID, no driver for Windows, Android or Linux
- 284 pcs in stock, leaves in 3–7 days
Ships knocked down. Four extrusions and four corners in one tube. Flat-packed freight runs about a third cheaper than a crated assembled frame.
Spare LED tubes. Tubes and filter strips are stocked for every size listed, so a dead emitter is a part swap rather than a new frame.
What the 70 inch frame fits
The active area is 1550 × 872 mm — a standard 70 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: 1576 × 902 mm, 9.5 mm deep
- Housing cut-out: leave 1580 × 906 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 room, boardroom, training centre.
70 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.

IR frame, infrared touch screen, overlay — the same part
Older drawings call this an IR overlay or simply a touch overlay: a frame that drops over an existing display without touching it. That is exactly the behaviour here — no bonding, no new firmware, no change to the LCD you already qualified. It is also the reason an infrared frame is the cheapest way to add touch to a product that is already in production.
Worth saying plainly: this frame does not need the display to be a touchscreen model, and it does not care what brand the TV is. It sits outside the glass and reads a finger through it. That is why a 2015 monitor and a 2024 signage panel take the same part.
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 →
