28.0 inch capacitive touch panel
28 inch panels are ordered for signage and gaming cabinets that want a flush glass front at a size where infrared starts to look dated. The sensor is one piece — there is no splicing at this diagonal.
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.
Panel, controller and cable in one carton
One G+G panel at 644 × 373 mm, the matched controller, a 1.8 m USB cable and the FPC tail you specified. Below 32 inch this ships from stock; above it, panels are built per order in two to three weeks.
- OD 644 × 373 mm · VA 620 × 349 mm · border 12 mm
- 6 H glass, 10-point, USB / I2C / RS232 controller included
- 358 pcs in stock
Cable and tail. 1.8 m USB cable as standard. I2C, RS232 and longer tails are the same price, specified at the drawing stage.
Controller included. Every panel ships with a matched controller, flashed and tested against that panel — not a generic board.
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) | 644 × 373 mm |
| Active area (VA) | 620 × 349 mm |
| Sensor | 636 × 365 mm |
| Printed border | 12 mm typical, 6 mm minimum |
Typical builds at this size: signage, gaming cabinet, retail display.
Solid outline = OD 644 × 373 mm · dashed = VA active area 620 × 349 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.
28.0 inch panel questions
What are the OD, VA and sensor sizes of the 28.0 inch panel?
Can I change the cover glass thickness?
Is a controller and cable included?
What is the lead time?
Our BOM says capacitive touch TP - is that the same part?
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.
