Problems solved by technology

At present, only CCD can be used to detect whether there are scratches or stains on the surface of the original glass substrate, but it cannot effectively detect the internal defects of the substrate, and internal defects are likely to cause damage to the substrate such as fragments in the subsequent manufacturing process

Abstract

An embodiment of the invention provides a glass detection device used for solving the technical problem of absence of an effective detection method for inside of an original glass substrate. The glass detection device comprises a microwave-transparent carrier, a microwave transmitting antenna and a microwave receiving antenna, wherein the microwave transmitting antenna and the microwave receiving antenna are located on two sides of the microwave-transparent carrier respectively, and opening surfaces of the microwave transmitting antenna and the microwave receiving antenna are opposite. A detection structure for glass inside is formed by the glass detection device, and a defect position of the original glass substrate can be detected accurately through combination with a scanning position of microwave beams. The glass detection device provided by the embodiment of the invention is high in detection speed and has certain detect type distinguishing performance, and a defect in the glass is positioned accurately. The embodiment of the invention further provides a glass detection method.

Description

technical field [0001] The invention relates to a display panel detection system and method, in particular to a glass detection device and detection method. Background technique [0002] In the production process of AMOLED (ie, Active-matrix organic light emitting diode) and other types of display panels, quality inspection is carried out on the original glass substrate (ie, bare glass) carrying the display unit and circuit to find quality defects. At present, only CCD can be used to detect scratches and stains on the surface of the original glass substrate, but it cannot effectively detect internal defects of the substrate, and internal defects are likely to cause damage to the substrate such as fragments during the subsequent manufacturing process. Contents of the invention [0003] In view of this, embodiments of the present invention provide a glass detection device and detection method, which are used to solve the technical problem of lack of effective detection means...
