Abstract

The invention provides a learning-based intelligent detection method and device for display screen defects, wherein the method comprises the following steps of: obtaining an image to be detected of ascreen; determining suspicious defect information of the image to be detected according to preset network parameters; extracting a defect characteristic value according to the suspected defect information; determining a final detection result according to the defect characteristic value; collecting all the final detection results as a result set; randomly selecting the final detection result in the result set as a sampling sample, re-detecting the sampling sample, and determining that the detection result is different from the final detection result as a result to be fed back; feeding back theresult to be fed back, learning and generating the next preset network parameter according to the result to be fed back; according to the next preset network parameter, the preset network parameter being updated, and according to the updated preset network parameter, the next image to be detected being detected.

Description

technical field [0001] The present application relates to the technical field of screen detection, in particular to a learning-based intelligent detection method and device for display screen defects. Background technique [0002] "New display industry", as one of the emerging strategic industries supported by the Chinese government, has made great progress in recent years with the active support of the government. At present, my country's liquid crystal display industry is experiencing a stage of constant expansion, increased shipments, and technological improvement. Display defect detection is an important link for display manufacturers to ensure the quality of shipments. At present, there are mainly two methods of screen inspection: manual inspection and AOI equipment inspection. Among them, the AOI equipment detection method has gradually replaced the traditional manual detection and become the mainstream detection method, but it also faces unstable defect benchmarks, ...
