Abstract

The invention discloses a defect detection device and method for a substrate. According to one aspect of the present invention, there is provided a defect detection device, which is used to detect defects of a substrate, and is characterized in that it includes: a substrate transfer part, which transfers the above-mentioned substrate along a preset direction; an image generation part, which is used to generate an image of the substrate; a unit pixel identifying unit that identifies unit pixels included in the substrate from the image of the substrate; a storage unit that stores a reference image of the unit pixel; an image comparison unit that compares the generated images of each unit pixel and The reference images stored in the storage unit are compared; the defect detection unit detects whether there is a defect in each unit pixel according to the comparison result; and the control unit is used to control each component in the defect detection device.

Description

technical field [0001] The present invention relates to an apparatus and method for detecting defects existing in a substrate in an Auto Repair System. Background technique [0002] What is described in this section merely provides background information about the present embodiments and does not constitute prior art. [0003] With the remarkable development of display equipment technology, the related technologies of various image display devices such as liquid crystal display or plasma display have been greatly improved. In particular, in an image display device that realizes large-scale and high-precision display, a high degree of technological innovation is progressing to reduce manufacturing costs and improve image quality. Glass substrates mounted on these various devices and used for displaying images are also required to have higher dimensional quality and higher-precision surface properties and conditions than ever before. When manufacturing glass for applications...
