DISPLAY PANEL INSPECTION DEVICE AND ITS INSPECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a display panel inspection device and its inspection method to automate a visual inspection process. SOLUTION: A loading section puts a display panel on a stage of a 1st position out of two or more stages and recognizes an inherent number of the display panel. A 1st image photographing section photographs the image of the display panel on the stage moved to a 2nd position to obtain 1st image data. A 2nd image photographing section photograph the image of the display panel on the stage moved to a 3rd position to obtain 2nd image data. The system controller finds defects on the display panel on the basis of the 1st image data, and finds defective appearance of the display panel on the basis of the 2nd image data. An unloading section takes out the display panel on the stage moved to a 4th position. Thus, the man-hours and the costs are saved while improving the reliability of the products.
