  • Publication number: 20240104717
    Abstract: A defect detection method includes obtaining a first screen image and a second screen image of a screen module, in response to determining a defect area in the first screen image, determining an image feature correlation between the first screen image and the second screen image, and determining a defect detection result of the screen module based on the image feature correlation. The first screen image is an image displayed by a display screen collected when the display screen of the screen module is in a first test state. The second screen image is an image displayed by the display screen collected when the display screen is in a second test state. The defect area indicates that the screen module has a display defect.
