摘要:
A testing apparatus for fixing and testing a LCD panel is provided. It mainly comprises a location frame (3) and an adjustable base (6) for fixing a camera set (7). The location frame and the adjustable base are connected together via a holder set (1). The adjustable base is able to be adjusted a distance between the location frame on the holder set. The location frame comprises a framework (33) with adjustable plates (4) on the edges of the backside of the framework. The adjustable plates are adjusted according to different sizes of the LCD panels (8) for placing LCD panels with different sizes. The LCD panel is supported by top-supporting devices (5) on the backside of the framework and located at the backside of the framework. Each edge of the framework is set with a movable shade (34) which is adjusted according to different sizes of the LCD panels for shading metal rims of the LCD panel. When the camera set takes pictures of the LCD panel, the boundaries of the screen area and the rims are clearly defined to make the testing module accurately test the defects of the LCD panel and to improve testing quality.
摘要:
In a product-quality inspection system and a method thereof, the system comprises: an inspection machine for positioning a product; a photographing apparatus for taking an iconology of the product, said photographing apparatus being mounted on the inspection machine so as to align the product, and constantly positioned relative to the product; and an inspection module for digital signal processing, said inspection module being connected to the photographing apparatus, wherein inspection data can be generated by using the photographing apparatus taking an iconology of the product irradiated or fed with typical signals for testing, and the iconology of the product can be converted into digital signals. The method comprises: dividing the iconologies of the products each into a plurality of pixel regions; and absolutely or relatively comparing the data of the product for inspection with the data of the qualified product per each corresponding pixel regions of the iconologies, with the latter being as a comparison level for the former, so as to realize the types and locations of defects in the product for inspection and to determine the product quality according to the criteria that has been input from outside through an interface and stored in the inspection module.
