Abstract

The invention discloses a detecting method for defects of a display screen module. The detecting method comprises the following steps: S1, detecting and recording non-substantial defects on a surface protection film of a display screen module; S2, detecting and recording all found defects when the display screen module is lightened; S3, filtering the non-substantial defects recorded in S1 from all the found defects in S2, so as to obtain the rest parts which are the real defects of the display screen module. According to the detecting method, non-substantial defects such as bubbles, scratches, dirties and the like on the protection film of a product can be filtered to prevent false alarm, thereby improving the accuracy of detection for the defects of the display screen module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a defect detection method of a display screen module. Background technique [0002] In the defect detection process of the display screen module, defects such as bubbles, scratches, and dirt on the product protective film are not substantive defects of the display screen module, and in the traditional detection technology, the detection camera cannot detect the above Instead of filtering the non-substantial defects, such non-substantial defects are photographed and recorded, an alarm is issued, and the currently detected display screen module is determined to be a defective product. It can be seen that this traditional detection technology cannot filter the non-substantial defects in the display screen module, thus causing false alarms, causing troubles to the defect detection of the display screen module, and reducing the accuracy of detection.
