Frequently Asked Questions

Q: What is the advantage of optical bonding over air bonding?

A: Optical bonding fills the air gap between the touch glass and LCD panel with a solid resin layer, eliminating internal light reflection, reducing parallax touch errors, and increasing structural impact resistance.

Q: Can the touch screen function reliably if liquid is spilled on the surface?

A: Yes. The integrated controller firmware features multi-frequency scanning algorithms that ignore static water pooling while maintaining active touch tracking for user fingers.

Q: What is the typical lifecycle availability for these industrial modules?

A: Components are selected from industrial semiconductor roadmaps to guarantee a minimum production availability and revision stability of 3 to 5 years, preventing unexpected redesigns.

Q: How are custom mechanical drawings submitted for review?

A: Engineering teams accept standard CAD formats including STEP, IGES, and DXF to verify mounting hole tolerances, cable exit locations, and bezel dimensions prior to sample fabrication.
