21.5 inch infrared touch frame
21.5 inch is where small all-in-ones start. Queue terminals, self-order kiosks and compact query stations converge on this diagonal because the enclosure stays under 600 mm wide and still fits a readable UI.
FOB Shenzhen, frame only, 1–50 pcs. Add $24 for 3 mm tempered glass. Volume tiers quoted on request.
The 21.5 inch, photographed before packing
Every unit is powered up and touched at nine points before it goes into the tube. At 502 mm wide the finished frame weighs about 2.8 kg, which is why it travels in a tube with foam ends rather than a flat carton.
- 502 × 298 mm outer, 476 × 268 mm active area
- 2–40 touch points, USB HID, no driver for Windows, Android or Linux
- 466 pcs in stock, leaves in 3–7 days
Corner joint. Cast corner block pinned into the extrusion — this is what keeps an 86 inch frame flat instead of bowing in the middle.
Packing. One frame per cardboard tube with foam ends. Crates start at 98 inch, where a tube stops being practical.
What the 21.5 inch frame fits
The active area is 476 × 268 mm — a standard 21.5 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: 502 × 298 mm, 9.5 mm deep
- Housing cut-out: leave 506 × 302 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: queue terminal, self-order kiosk, query station.
21.5 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.

21.5 inch frame questions
What is the outer size of a 21.5 inch frame?
Can I get this size with a different bezel?
How many units of the 21.5 inch frame fit in a carton?
Do you supply the tempered glass with the frame?
Is this an IR touch frame or an infrared touch screen?
Naming, for the benefit of your purchasing team
Multi touch frame, infrared multi-touch frame, IR touch panel — all of them refer to the same assembly described on this page. The touch count is set by the controller and the LED pitch, not by the name, so a 10-point and a 40-point version are physically identical from the outside.
Two questions decide the fit on a retrofit: the lit area of the display (not the diagonal on the box) and whether the USB port stays alive when the screen sleeps. Get those right and the install is fifteen minutes with a screwdriver.
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 →
