  • Device and method for inspecting a sealing member
    Patent number: 9568303
    Abstract: A sealing inspection device includes a scan unit through which a display device substrate including a top plate coupled to a bottom plate by a sealing member in the sealed area passes; and a photographing unit through which the display device substrate which has passed through the scan unit, further passes. The scan unit generates coordinate values of the sealed area of the display device substrate, detects a defective region in the sealed area of the display device substrate, and includes a plurality of scan cameras. The photographing unit generates an image of the sealed area of the display device substrate using the generated coordinate values, measures an effective sealing width of the sealed area using the generated image, and comprises a measuring camera.
