18.5 inch capacitive touch panel
18.5 inch is the smallest size that reads as a "wall panel" rather than an instrument screen — common for access control and building directories.
FOB Shenzhen, G+G panel with controller and 1.8 m USB cable, 1–50 pcs. Custom coating, glass thickness and printed border quoted on drawing.
How the 18.5 inch leaves the line
Glass bonded to sensor, FPC bonded to the tail, then touched at the centre and all four corners before vacuum packing. The printed border on this size is 11 mm, which is what you have to leave free in the housing.
- OD 432 × 252 mm · VA 410 × 230 mm · border 11 mm
- 6 H glass, 10-point, USB / I2C / RS232 controller included
- 394 pcs in stock
FPC tail. The tail can leave on any of the four sides, same-side or opposite-side contact, without changing the outline.
Cable and tail. 1.8 m USB cable as standard. I2C, RS232 and longer tails are the same price, specified at the drawing stage.
Three numbers, not one
Unlike an infrared frame, a capacitive panel is defined by three dimensions. The OD is the outside of the glass and is what your housing is cut to. The VA is the visible area your UI is designed against. The sensor is the ITO pattern inside the printed border.
| Outline (OD) | 432 × 252 mm |
| Active area (VA) | 410 × 230 mm |
| Sensor | 424 × 244 mm |
| Printed border | 11 mm typical, 6 mm minimum |
Typical builds at this size: access control, building directory, fitness machine.
Solid outline = OD 432 × 252 mm · dashed = VA active area 410 × 230 mm

What happens after the carton is open
A capacitive panel needs no calibration — the sensor is bonded to the glass, so the coordinates are geometry rather than measurement. What it does need is the right settings for your glass stack, and a bonding process that does not trap air.
Plug and play over USB
Windows, Android, Linux and ChromeOS pick it up as a HID touch digitizer with nothing installed. I2C and RS232 versions available for boards without a USB host.
Firmware tuned to your stack
Threshold, report rate, edge suppression and ESD level are set for the cover glass you specify — then shipped as a settings file you can clone across a batch.
Bonding and install guidance
OCA versus tape versus air gap, FPC bend radius, shield grounding under 4 Ω. We will join the first bonding run by video if it is your first one.
18.5 inch panel questions
What are the OD, VA and sensor sizes of the 18.5 inch panel?
Can I change the cover glass thickness?
Is a controller and cable included?
What is the lead time?
Is this a capacitive touch screen or only a panel?
Reading a capacitive drawing without guessing
When the outline is not standard, the enquiry usually says custom capacitive touch panel or capacitive touch screen custom size. That is the normal way to order: send the outline, the active area, or the glass you already buy, and the sensor and tail are re-laid to match. Tooling is a drawing and a sample, not a mould.
