Abstract
A display defect detection method, includes: collecting at least one display image of at least one display to be detected; extracting a plurality of band-limited intrinsic mode function components from a display image in the at least one display image by using a complex variational mode decomposition method; extracting and fusing the plurality of band-limited intrinsic mode function components of the display image by using a convolutional neural network, so as to obtain an average brightness value and a brightness uniformity of the display image; and determining whether a display to be detected in the at least one display to be detected corresponding to the display image is qualified according to a preset classification rule and the average brightness value and the brightness uniformity of the display image.
