Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a detection system, method, device and computer-readable storage medium. Background technique [0002] With the development of display technology, the resolution of display devices is getting higher and higher, and the requirements for the production process of display devices and defect detection in production are getting higher and higher. The traditional defect detection method of display devices is manual visual inspection, which consumes a lot of manpower and is inefficient. Due to the subjectivity of manual detection and visual fatigue caused by long-term work, the stability and accuracy of detection are poor, and it is impossible to form Unified testing standards. Therefore, using machine vision technology to perform high-efficiency, high-stability, and high-accuracy on-line detection of display devices has gradually become ...
