| Summary: | 碩士 === 國立中興大學 === 機械工程學系所 === 96 === The traditional CRT Monitor is large and it will harm human body because of radiation. By comparison with the traditional CRT screen, the TFT-LCD screen is economical electricity, light-thickness, low-level radiation and doesn’t occupy volume so the TFT-LCD screen will substitute for the CRT screen. TFT-LCD screen has overcome the low response time and high cost with the improvement of the Science and Technology. So the TFT-LCD Display will be the key point of the Flat Panel Display in the future.
Better performance product and perfect quality will be the main target for the TFT-LCD manufacturer. The defects of TFT-LCD contain point defect, line defect, the outward-appearance defect and Mura. Mura is the most difficult to be solved and inspected. There are two kinds of inspection which are human-inspection and auto optical inspection. The auto optical inspection is not so good to screen out Mura. How to use human-inspection more effectively will be the first priority. The thesis will research the factor of the human-inspection that will influence your judgment. By the experiment, the root cause will be found out and the yield will be improved in the factory.
