Abstract

The invention provides a screen defect filtering method and device and a storage medium. The method is used for filtering detected defects, and the method comprises at least one of the following steps: determining whether to filter the defects or not according to comparison between a probability value of the unfiltered defects and a preset card control threshold value; determining whether to filter the defect or not according to comparison between the area of the unfiltered defect and a preset area threshold value; and calculating the similarity between the unfiltered defects and the sample picture, and determining whether to filter the defects or not according to the comparison between the similarity and a preset similarity threshold. The method has the advantages of low labor cost, highfiltering precision, high efficiency and few subjective influence factors.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a screen defect filtering method, device and storage medium. Background technique [0002] Display screens such as LCDs are widely used in industries such as computers, communications, and consumer electronics. The manufacturing process of the display screen is relatively complicated, which may lead to defects in the display screen, so it is necessary to perform display screen defect detection. In the prior art, algorithms are usually used for defect detection. [0003] However, various minor defects or untrue defects with interference will inevitably appear in production, transshipment or other links. For example, fine dust in the air will cause bubbles to form on the LCD screen, or the screen will be stained during the production process, or there will be slight bruises during handling, or minor or unreal defects caused by uneven coating of the top glue. The existence of th...
