Detection background:

In the manufacturing process of modern display panels, the requirements for product quality are extremely stringent. Defects such as dust, foreign matter and dirt can seriously affect the performance and service life of display panels. Therefore, an efficient foreign object detection system is essential to ensure product quality.

Testing Requirements:

• High sensitivity：capable of detecting tiny dust and foreign objects.

• High accuracy：accurately distinguish between foreign objects and normal patterns or markings on the panel.

• High speed：fast scanning of large panel areas, adapting to the speed of production lines.

• Ease of operation：simple to operate and easy to integrate into automated inspection processes.

Detection programme:

POMEAS Line Laser Sensors

• High-precision scanning: scanning accuracy of 1um enables detection of extremely small defects.

• High resolution: provides clear scanning images for subsequent image processing and analysis.

• Fast response: fast scanning of large-size panels without affecting production line efficiency.

• Stability: maintains stable scanning performance under a variety of operating conditions.

Supporting software analysis system

• Intelligent analysis: using image processing algorithms to intelligently identify defects such as foreign matter and impurities.

• Classification identification: able to distinguish between different types of defects, such as dust, foreign matter and dirt.

•  

  Report Generation: automatically generates inspection reports, recording the type, location and number of defects.

   

Combined with a high-definition industrial camera and intelligent analysis software, the POMEAS line laser sensor provides an efficient and accurate solution for foreign object detection in display panels. This solution not only improves the accuracy and efficiency of the inspection, but also helps to reduce the production cost and enhance the market competitiveness of the products.
