At Brownopto, quality control is a crucial part of the production process. In order to ensure that each TFT display module meets the highest quality standards, we have implemented a comprehensive and strict inspection process. Here are the eight key inspection methods we perform during the production process:
Surface Quality, Frame, Connectors, Labeling, Uniformity, and Dimensions are thoroughly inspected for defects, integrity, and compliance.
It's a crucial part of our comprehensive inspection process, where we test for various electrical parameters to ensure the product meets required specifications. Any defects or abnormalities found are addressed before shipment.
It's an important step in our comprehensive inspection process, where we conduct various tests to ensure the product meets required specifications and performs as intended. Any issues found are addressed before shipment to ensure customer satisfaction.
We use specialized equipment to test visual performance, focusing on appearance, optics, and compliance with standards. This ensures our products meet optical performance standards and exceed customer expectations.
Environmental Reliability Testing ensures our TFT displays perform reliably in various conditions, meeting standards and addressing any issues found.
Datasheet Verification is a critical step in our inspection process. It ensures the accuracy and completeness of product information, providing reliable and transparent specifications for our customers.
We rigorously apply these testing measures to all our products prior to shipment to ensure optimal performance and reliability. In addition to the outlined tests, certain displays may undergo supplementary quality assurance processes tailored to their specific requirements and intended applications. These additional steps are designed to further enhance the durability and robustness of our products before they are shipped to our customers.

Our quality inspection equipment includes six fully automated production lines, each equipped with online particle AOI inspection equipment and automatic LCM defect AOI inspection systems. These devices utilize high-resolution imaging technology and advanced image processing algorithms to accurately detect small particles and pressure marks on the surface of the product, including those from FPC/IC bonding. They also achieve 100% inspection of particle quantity and positional deviation, ensuring that our products meet the highest standards of quality. Through the use of these advanced devices, we can guarantee the quality and reliability of our products, providing our customers with dependable products.
Our inspection equipment includes six fully automated production lines with online particle AOI and automatic LCM defect AOI systems. These advanced devices accurately detect small particles and pressure marks on the product surface, achieving 100% inspection of particle quantity and positional deviation for all COG and FOG products. This ensures the highest quality standards for our products.
Our AOI inspection equipment is designed to replace manual inspection, eliminating the impact of human fatigue and significantly reducing the likelihood of human error. After undergoing AOI testing, our products have a functional failure rate of less than 300 PPM, greatly improving product quality. Our systems can accurately detect various defects, including point defects (bright or dark spots) with a size of 5μm, foreign object defects with a size of 50μm, 2% detection accuracy for Mura defects on gray screens, and ±0.0002 accuracy for low contrast color defects. They can also detect a variety of other defects, such as line defects, backlit foreign objects, display abnormalities, edge light leakage, color temperature deviation, and various types of Mura defects.
Our reliability testing equipment includes a wide range of tools to ensure the highest quality and durability of our products. Key equipment includes:
To ensure our products meet the most stringent reliability standards, we use advanced testing equipment, including spray chambers, UV aging chambers, luminance meters, spectrometers, and thermal shock test chambers, among others.
Every product undergoes rigorous aging tests on our Product Aging Machine prior to shipment, ensuring reliability and quality. This process simulates extended usage scenarios to identify and address any potential issues before the products reach our customers.
