3. What mounting and bonding options are available?
Standalone touch panels can be evaluated for frame bonding or optical bonding with compatible LCD modules. Suitable assembly methods depend on mechanical structure, available bonding space and application conditions. MAXEN can review mounting requirements and recommend appropriate integration methods.
Q
4. Which components can be customized for OEM projects?
▼
4. Which components can be customized for OEM projects?
Customization options include cover glass dimensions, border printing, FPC routing, connector position and selected surface treatments. Changes to sensor structure or controller configuration require additional engineering review. Tooling requirements, feasibility and development costs are confirmed before sampling.
Q
5. How is touch performance verified under industrial operating conditions?
▼
5. How is touch performance verified under industrial operating conditions?
Touch performance should be evaluated under actual operating conditions, including temperature changes, electrical interference and intended input methods. Glove operation, moisture tolerance and multi-touch functionality require configuration-specific validation. MAXEN recommends testing samples with final host hardware and enclosure design.
