Abstract

The invention discloses a detection system and a detection method for foreign matters in CG and OCA interlayers of a display screen. The detection system and the detection method are used for improving the yield of finished display screens. The system comprises a light source control module, a first coaxial illumination module, a second coaxial illumination module, a first industrial imaging module, a second industrial imaging module, a motion control assembly, a CG supporting platform and an image processing workstation. The light source control module is connected with the first coaxial illumination module, the second coaxial illumination module and the image processing workstation; the first coaxial illumination module and the second coaxial illumination module are fixed to the upper portion and the lower portion of the CG supporting platform respectively. The image processing workstation is connected with the first industrial imaging module and the second industrial imaging module. The first industrial imaging module is fixed above the first coaxial illumination module, and the second industrial imaging module is fixed below the second coaxial illumination module; the motion control assembly is connected with the first industrial imaging module and the image processing workstation.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a detection system and detection method for foreign objects interlayered between CG and OCA of a display screen. Background technique [0002] Cover glass (CG, Cover Glass) is a structure that exists in LCD and OLED liquid crystal display panels. It is attached to the top of LCD and OLED liquid crystal panels to protect the display panels. Before bonding, a protective film will be attached to the upper surface of the CG with static electricity, and a layer of OCA optical adhesive will be attached to the lower surface of the CG. There is a layer of heavy film outside the OCA adhesive layer to protect the OCA adhesive from secondary pollution by the environment. When it needs to be attached, the heavy film under the OCA optical glue is torn off and attached to the surface of the LCD or OLED display panel, and the lamination process is completed. [0003] At present, CG is...
