GT-CTS-Y27

Yes — with the right firmware the 27" panel tracks independent gestures, so one person zooming a map and another writing notes won't fight each other. Tell us your app (whiteboard, CAD review, game) and we'll set the touch-point split and palm-rejection accordingly.

Mostly optical. The touch layer just needs the right surface: AG (anti-glare) cuts harsh window reflections, AR (anti-reflection) boosts contrast, AF (anti-fingerprint) keeps it clean. We can combine AG+AR on the cover glass so the LCD underneath stays readable without changing the touch performance.

For indoor meeting rooms, a 1–2 mm air gap is fine and cheaper. For semi-outdoor kiosks or bright showrooms, OCA optical bonding removes the double-image reflection and makes the image look "closer" to the finger — better perceived accuracy. We'll advise based on where the unit will live, not just the budget.

Don't clamp the glass directly. Use a frame that supports the cover-glass edge with uniform pressure and leaves a 2–3 mm soft gasket between metal and glass. The sensor itself is fragile only at the very edge — the center takes normal load fine.

Yes, the active sensor can go within ~3 mm of the glass edge. But the last few mm near the frame need special border printing and controller tuning, otherwise the very edge feels dead. Send your ID render and we'll tell you the realistic active-margin we can achieve.

The cover glass surface handles regular alcohol wipes and glass cleaner — just don't spray liquid directly at the FPC exit. For hospitals or food courts we add an AF coating so smudges don't build up, and the controller ignores a damp cloth dragged across it.
