Quality Control

Reliable display products begin with disciplined quality control at every stage of manufacturing.

At ZC Display, quality control is integrated into product development, component management, assembly, functional testing, and final shipment inspection. Our objective is to deliver display solutions that meet agreed specifications and perform reliably in commercial and industrial applications.

For standard products and customised OEM/ODM projects, we apply practical inspection procedures based on the product type, configuration, and project requirements.

Quality Control Throughout Production

Our quality process includes key checks before, during, and after production:

  • Incoming inspection of displays, touch panels, PCBs, power supplies, enclosures, cables, and other major components

  • Verification of approved materials and configured components before assembly

  • Process inspection during mechanical assembly, wiring, integration, and finishing

  • Functional testing of display performance, touch response, power operation, interfaces, network connectivity, and system functions

  • Cosmetic inspection for screen condition, enclosure finish, labels, logos, and overall appearance

  • Mechanical checks for dimensions, mounting points, assemblies, and accessories

  • Final product inspection before packaging and shipment

  • Packaging verification to help protect products during transportation

Functional Testing

Every display project has different functional priorities. Testing can be aligned with the agreed product configuration and application needs.

Depending on the product, functional checks may include:

  • Screen brightness, colour display, backlight operation, and image quality

  • Touch accuracy, response, and multi-touch performance

  • Android, Linux, or Windows system startup and basic operation

  • HDMI, USB, LAN, Wi-Fi, Bluetooth, RS232, and other interface functions

  • Audio, camera, scanner, printer, NFC, RFID, or other integrated peripherals

  • Power stability and system restart performance

  • Basic aging or burn-in testing when required by the project

  • Installation and mounting compatibility checks for customised products

Quality for Customised Projects

Customised display projects require additional attention because the final product may include application-specific hardware, software, structural, or branding requirements.

Before mass production, we work with customers to confirm key project details, including:

  • Approved product drawings and dimensions

  • Display and touch specifications

  • Mainboard and operating system configuration

  • Interface and peripheral requirements

  • Enclosure finish, logo placement, and labelling

  • Packaging requirements and accessory lists

  • Product inspection requirements and acceptance criteria

This early confirmation process helps reduce production risk and supports more consistent results during volume manufacturing.

Compliance Support

For projects requiring market-specific compliance, ZC Display can support product configurations designed around applicable standards and documentation requirements, including CE, FCC, and RoHS where relevant.

Certification availability and scope can vary by product model, hardware configuration, destination market, and customisation level. Please confirm the required compliance standards with our team during project evaluation so that they can be considered in the proposed solution.

Continuous Improvement

Quality control does not end with shipment. Feedback from customers, field applications, service cases, and repeat orders helps us improve product designs, production procedures, and technical support over time.

Our goal is to provide not only a compliant product at delivery, but also a stable supply solution that supports your project throughout its lifecycle.
