| 1 | Manufacturer Identity and Capability | Confirm whether the supplier manufactures the interactive display, assembles it, or sources finished products from another factory. Check that the proposed production site matches the supplier’s documentation. | Current business registration details, factory address, production-line overview, and a live or recent factory audit. Verify the legal entity and site independently. |
| 2 | Quality Management | Check whether the supplier has a valid ISO 9001 quality-management-system certificate covering the relevant manufacturing site and product scope. ISO 9001 does not, by itself, certify a particular screen model. | Certificate number, issuing certification body, covered site and scope, validity dates, and a way to verify the certificate with its issuer or accreditation database. |
| 3 | Electrical and Product Safety | Identify the applicable safety requirements for the intended destination market. IEC 62368-1 is a safety standard for audio/video and information and communication technology equipment; applicability depends on the product and market. | Test report or certificate for the exact model, including model number, tested configuration, standard edition, laboratory details, and report date. |
| 4 | Market Access and EMC | For products placed on the EU market, check applicable CE obligations, including relevant electromagnetic-compatibility requirements. CE marking is the manufacturer’s declaration of conformity, not a general independent quality certification. | EU Declaration of Conformity listing the exact model and applicable legislation, plus supporting EMC test reports. For other destinations, request documentation for the applicable local requirements. |
| 5 | Hazardous-Substance Compliance | Where required by the destination market, check RoHS-related documentation for the finished product and relevant materials. A supplier statement alone may not establish compliance for every component or configuration. | Model-specific declaration and supporting test or supplier-chain records. Confirm the document’s scope, date, product configuration, and applicable market rules. |
| 6 | Display Performance | Compare the offered screen size, resolution, brightness, contrast, viewing angle, refresh rate, and rated operating hours against the required use case. Brightness and other performance can vary by panel and configuration. | Datasheet for the exact configuration, panel specification, measurement conditions, and sample-unit measurements where performance is critical. |
| 7 | Touch and Compatibility | Check touch technology, supported touch points, response behavior, palm rejection if needed, and compatibility with the intended operating systems, computers, and conferencing equipment. | Touch-controller and driver details, compatibility list, interface specifications, and a trial sample tested with the buyer’s actual devices and software. |
| 8 | Customization and Integration | Confirm which changes are available, such as screen size, ports, camera or microphone modules, operating system, interface language, logo placement, packaging, and mounting options. Clarify minimum order quantities and any engineering charges. | Written configuration sheet, approved drawings or samples, interface and software requirements, tooling or setup costs, minimum order quantity, and change-control process. |
| 9 | Production and Inspection Controls | Ask how incoming components, assembly, firmware loading, calibration, burn-in, and final inspection are controlled. Agree on acceptance criteria before production rather than relying on a general quality claim. | Quality-control plan, inspection checklist, sample inspection report, serial-number traceability process, defect-handling procedure, and agreed pre-shipment inspection plan. |
| 10 | Warranty and After-Sales Support | Compare warranty duration and coverage, exclusions, repair or replacement process, spare-parts availability, technical support hours, response targets, and responsibility for shipping costs. Warranty terms are supplier-specific and should be confirmed in writing. | Written warranty policy and sales contract defining coverage start date, service process, turnaround expectations, spare-parts terms, support contacts, and remedies for recurring or batch-level defects. |
