As an important part of smart phones, the quality of mobile phone screens directly affects the user experience. Therefore, in the production process, it is particularly important to conduct strict quality inspections on mobile phone screens.
[0003] At present, the automatic optical inspection (AOI) technology is widely used in the quality control of mobile phone screens.
