AU Optronics 10.1-inch G101EAN TFT-LCD Module Incoming Inspection Specification A Specification IIS Standard
AU Optronics G101EAN series LCD module feeding inspection standard
In the production and application of LCD display modules, incoming inspection is a key link to ensure product quality and reliability. AU Optronics, as a leading global supplier of TFT-LCD, has developed detailed incoming inspection specifications (Grade A) for its 10.1-inch G101EAN series modules. This article will be based on the core content of the AU 10.1-inch G101EAN series (A) specification, outlining its main framework and key points to help readers understand the practical significance of this standard in quality control.
1. Scope of application and inspection responsibilities
The G101EAN series (A) IIS standard specification clearly states that it applies to the G101EAN series TFT-LCD modules supplied by AU Optronics, covering inspection requirements for electrical performance, appearance, and external dimensions. The buyer (customer) shall complete the inspection within 20 natural days from the date of delivery and bear the corresponding costs. If unacceptable defects are found in the entire batch of products, the buyer shall notify the seller in writing within the inspection period, and no later than three working days after the end of the inspection period. If the buyer does not raise any objections within the specified period, it shall be deemed as acceptance of the batch of products by default.
2.Sampling method and judgment criteria
The inspection sampling is based on MIL-STD-105E standard, using normal inspection and single sampling plan, with an inspection level of Level II. The acceptable quality level (AQL) is set at 1.0% for major defects and 2.5% for minor defects. When sampling, if the sample size is equal to or exceeds the batch size, perform a full inspection. The acceptance number (Ac) and rejection number (Re) are strictly determined according to the standard table. This hierarchical defect management approach ensures inspection efficiency while also considering the impact of defects of different severity levels on product use.
3.Testing environment and instruments
In order to ensure comparability and repeatability of the results, the specifications have put forward clear requirements for environmental conditions: room temperature of 20-25 ℃, relative humidity of 65 ± 5%, display screen surface illumination of 300-700 lux (standard 500 lux), observation distance of about 35 ± 5 centimeters, line of sight perpendicular to the module surface, and allowable viewing angle deviation of ± 10 °. The inspection instruments include pattern generators (such as LD-2000), video boards that comply with AU signal specifications, and luminance colorimeters (such as Topcon BM-7). These conditions minimize the interference of external factors on inspection and judgment to the greatest extent possible.
4. Defect classification and electrical inspection rules
Defects are divided into primary defects and secondary defects. Major defects may lead to product failure or significantly reduce the usability of its intended use; Minor defects have a relatively small impact on effective use.
In terms of electrical inspection, the specifications provide detailed allowable limits for point defects:
Number of highlights ≤ 2
Number of dark spots ≤ 3
Total number of defects ≤ 5
Continuous defects: It is not allowed to have three or more consecutive bright spots, dark spots, or mixed spots; Two consecutive dark spots are allowed to not exceed one pair; The distance between bright and dark spots should be ≥ 5mm
Of particular note is the introduction of a 5% neutral density filter for small bright spots: if visible through the filter, it is considered a bright spot; If it is not visible, it shall be counted as a small bright spot, and the total number of small bright spots shall not exceed 10. The inspection pattern includes five standard modes: black (detecting bright spots), white (detecting dark spots), red, green, and blue (detecting both bright and dark spots).
Regarding Mura (uneven display), the specification requires it to be invisible under a 5% ND filter or determined by equivalent samples (JND2.5). When working at ambient temperatures exceeding 50 ℃, Mura should not be visible even with a 1% ND filter applied. In addition, the image residue must disappear within 5 seconds after switching the test pattern.
5. Appearance Inspection Specification
The appearance inspection covers defects such as particles, linear foreign objects, scratches, dents, bubbles, etc. within the effective display area. For example, when the average diameter D of circular particles is ≤ 0.15mm, it is ignored; 0.15 ＜ D ≤ 0.50mm and quantity ≤ 3 are acceptable; D>0.50mm is not allowed to exist. When the width W of linear defects is ≤ 0.05mm, ignore it; 0.05 ＜ W ≤ 0.10mm and a length between 0.5~2.0mm is acceptable. The border must not have burrs, dents, or assembly failures that may cause harm to the human body. In terms of labels, it is prohibited to have no labels, incorrect label content, or incorrect position. Labels are allowed to overlap but must not be blurred or damaged to the point where barcodes cannot be scanned.
6. Precautions for use
At the end of the G101EAN series (A) IIS standard, more than 15 operating precautions are listed, emphasizing avoiding twisting or bending modules, dust and oil mist prevention, correct power timing, avoiding long-term display of fixed patterns (to prevent image residue), anti-static, anti strong vibration impact, and avoiding use in high temperature, high humidity, or direct sunlight. Special reminder to users not to disassemble the module by themselves, and to be aware that high backlight voltage may cause electric shock.
Conclusion
The AU Optronics G101EAN series feed inspection standard is a rigorous and detailed technical document that complies with the internationally recognized MIL-STD-105E sampling logic and combines the unique point defects of the LCD display industry Mura、 Professional judgment methods such as image residue. For enterprises that purchase and use this series of modules, strictly following this standard for incoming inspection not only helps maintain product quality, but also effectively defines the responsibility boundaries between supply and demand, reducing quality disputes.
