| Abstract: | The point defects such as bright points, dark points, flash points and broken bright point that often occur in the process of TFT-LCD production are analyzed. The device, method and process of the poinl defects detection are ex- plained. The point defects are detected and repaired by using bomb and ITO insulation. Among them, ITO insulation is most effective in repairing the defects. The success rate of point defects repairing is improved from 450A to 80%. |
