Frequently Asked Questions

Q: What is the typical lifecycle and supply continuity for these modules?

A: Guaranteed minimum 5-year production availability with strict component change notification protocols issued 6 months prior to any internal material revision.

Q: Can the touch panel function reliably when exposed to rain or water splashes?

A: Yes. The onboard capacitive touch controller features specialized firmware algorithms that filter out false touch inputs caused by flowing water droplets or high surface moisture.

Q: Is optical bonding required for indoor access control terminals?

A: Optical bonding is optional for indoor use, but strongly recommended for semi-outdoor terminals to eliminate internal parallax distortion and suppress ambient glare under direct sunlight.

Q: What is the minimum order quantity for custom FPC or cover glass printing?

A: Customizations involving logo printing or FPC pinout modifications start at modest batch quantities, with specific thresholds dependent on the exact display diagonal size.
