Benefits of technology

This technology helps identify any issues or flaws on the surface of an electronic device's display screens quickly without requiring human interference. It involves taking images through special lenses mounted at various locations around it for analysis purposes. By comparing these taken frames against reference maps stored within memory, errors may appear due to imperfections such as uneven surfaces between them. Additionally, this method allows us to estimate how well they work over their entire range of viewing angle (their normal direction). Overall, this system makes sure we have accurate results even when there aren’t perfect details about what happened during testing.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the accuracy and effectiveness of conventional methods that rely on human visual observation alone for inspecting LC (Liquid Crystal Display) panels due to limitations like spot size issues caused by poor image resolution compared to other areas around them.

Abstract

The invention provides a display screen defect monitoring system based on image recognition and a detection method thereof, and relates to the technical field of screen defect detection. The display screen defect monitoring system comprises a detection assembly line and a main control computer, and the detection assembly line comprises at least one detection station used for detecting a display screen; the detection station is a darkroom in which a lighting jig for loading a display screen and an image acquisition module are arranged, the main control computer comprises an image processing module, an image comparison module, a good product estimation module and a sample library, and a plurality of illuminating lamps are arranged in the detection station. According to the invention, the camera is used for photographing, the image processing module is used for processing the obtained picture, and the image comparison module is used for comparing the processed picture with a non-defective product pre-estimated picture, so that the defective products in the display screen can be effectively detected, compared with the traditional manual detection, the omission ratio and the false detection ratio are greatly reduced, the detection speed is high, the detection precision is high, and the detection efficiency of the display screen is effectively improved.
