18.5 inch infrared touch frame
18.5 inch is the smallest size that still reads as a wall-mounted panel instead of an instrument screen. Access control, gym equipment and building directories use it because the cut-out matches the 18.5 inch signage LCDs already sitting in distribution.
FOB Shenzhen, frame only, 1–50 pcs. Add $22 for 3 mm tempered glass. Volume tiers quoted on request.
What is in the 18.5 inch box
One frame at 436 × 260 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.
- 436 × 260 mm outer, 410 × 230 mm active area
- 2–40 touch points, USB HID, no driver for Windows, Android or Linux
- 424 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 18.5 inch frame fits
The active area is 410 × 230 mm — a standard 18.5 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: 436 × 260 mm, 9.5 mm deep
- Housing cut-out: leave 440 × 264 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: access control panel, gym console, building directory.

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.

18.5 inch frame questions
What is the outer size of a 18.5 inch frame?
Can I get this size with a different bezel?
How many units of the 18.5 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?
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 →
