Detection method and device of display panel

Abstract

The embodiment of the invention discloses a detection method and device of a display panel. The detection method comprises the steps of collecting a first detection image of the display panel and obtaining gray-scale values of all pixels in the first detection image; determining the pixels of which the gray-scale values surpass a preset gray-scale range in the first detection image as first pixels, determining a first communication area formed by all the first pixels in the first detection image, and calculating the aspect ratio of the first communication area; searching for target parameters matched with the aspect ratio of the first communication area, in a preset established database, and determining the target type corresponding to the target parameters as the type of the display panel. According to the embodiment of the invention, the full automatic detection of the display panel types is achieved, the detection device can be used for automatically detecting and judging the type of the display panel, so that no manpower consumption is needed, and the manpower cost is reduced; besides, the full automatic detection process of the detection device is high in speed, and the detection efficiency can be effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to a display panel detection technology, and in particular, to a display panel detection method and device. Background technique [0002] During the manufacturing process of existing display panels, various inspections need to be carried out to confirm that the display panels being manufactured are free of defects, so as to prevent defective products from flowing to the back-end to continue operations, resulting in a lot of waste of module consumables and production time. Various inspections of the existing display panel include at least data test, visual inspection, overall test, final test and the like. [0003] Visual inspection is light on inspection, mainly for display inspection of formed panels. The existing lighting inspection procedure is: automatically take pictures of the forming panels placed on the lighting machine; then the staff judges whether there are defects in the forming panels according ...
