    • An inspection apparatus and inspection method for liquid crystal display devices are disclosed, wherein a final inspection for completely manufactured liquid crystal display devices is performed using a visual-light inspection apparatus, whereby high productivity due to improved inspection accuracy and reduced inspection time can be accomplished. With the inspection apparatus and inspection method, defects of a plurality of glass panels can be automatically inspected based on analyzed information of an entire screen of each glass panel using a plurality of vision cameras, whereby improved inspection accuracy and improved product quality can be accomplished and reduced inspection time can result in improved productivity of liquid crystal display devices. Further, by quantifying screen defects of the plurality of glass panels, defects of glass panels due to failures of manufacturing processes or design failures and other problems attendant on the defects can be prevented.
    • 公开了一种用于液晶显示装置的检查装置和检查方法,其中使用视光检查装置进行完全制造的液晶显示装置的最终检查,从而可以实现由于提高检查精度和减少检查时间而产生的高生产率 。 利用检查装置和检查方法,可以基于使用多个视觉摄像机的每个玻璃面板的整个屏幕的分析信息来自动检查多个玻璃面板的缺陷,从而可以实现提高的检查精度和提高的产品质量, 减少的检查时间可以提高液晶显示装置的生产率。 此外,通过量化多个玻璃面板的屏幕缺陷,可以防止由于制造过程的失败或设计失败导致的玻璃面板的缺陷以及与缺陷有关的其他问题。
