Quality System: Uncompromising Standards, Reliable Performance Introductory 

At Wandisplay, quality is the foundation of everything we do. As a dedicated manufacturer of small and big-sized LCMs, we have established a comprehensive, closed-loop quality management system. From stringent incoming material inspections to precision manufacturing in Class 100 cleanrooms, and rigorous reliability testing, every step is meticulously controlled. We are committed to delivering superior display modules that meet the highest international standards and exceed customer expectations.

1. Quality Policy & Certifications

• Quality Policy: Our core philosophy is "Quality First, Integrity Foremost."
• Authoritative Certifications: We hold internationally and domestically recognized certifications, including ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System), and ISO 13485 (Medical Device System), demonstrating our capability to deliver highly reliable products.

2. Strict Incoming Quality Control (IQC)

• Core Material Inspection: We enforce rigorous inspection standards for all critical materials.
• Supplier Management: Through our Approved Vendor List (AVL) management system, we eliminate defective materials at the source.
• Inspection Methods: We utilize Automated Optical Inspection (AOI) and high-precision measuring instruments to strictly screen dimensions, appearance, and electrical performance.

3. Precision Manufacturing & In-Process Quality Control (IPQC)

• Cleanroom Environment: Core processes, including COG/FOG bonding and lamination, are conducted in a Class 100 Cleanroom. Strict control over temperature, humidity, and micro-particles prevents Mura (display non-uniformity) and foreign object defects.
• Critical Process Control:
  • Bonding Process: Real-time monitoring of temperature, pressure, and time parameters during ACF thermal compression ensures optimal pin conductivity and peel strength.
  • Optical Bonding: Strict control over bubble removal, dust-free spots, and lamination precision for full-bonding processes.
• Traceability: We guarantee full traceability of material batches for every product run.

4. Comprehensive Reliability & Outgoing Quality Control (OQC)

• Environmental & Life Testing: Our laboratory is equipped to conduct tests such as High-Temperature/High-Humidity storage & operation (e.g., 85℃/85%RH), Thermal Shock, Vibration, and Drop tests.
• Optoelectronic Testing: We perform 100% full inspection or high-ratio sampling on optical metrics, including brightness, contrast, color gamut, viewing angle, and response time.
• Outgoing Standards: We strictly adhere to international sampling standards (MIL-STD-105E) to ensure every batch delivered meets AQL requirements.

5. Continuous Improvement & Customer Service
We are committed not only to current quality but also to long-term optimization and service excellence.

• Customer Complaint Response: We offer a rapid response mechanism (7×24 hours) and utilize 8D reports to ensure closed-loop problem resolution.
• Data Analysis & Optimization: We conduct in-depth analysis of production yield and customer feedback data to drive continuous process iteration and improvement.
