[20] In addition, a paste container 10 in which the paste 8 is stored is positioned within a movement range of the shaft on which the coating needle 2 is installed, and the paste container 10 has the coating needle 2 in addition to the paste 8. The detergent 12 used for washing) is stored.
[21] Only one coating needle 2 of a predetermined size is installed in the paste coating apparatus as described above, and the coating needle 2 is immersed in the paste container 10 so that the paste 8 is buried. The paste 8 is applied to 6).
[22] Looking at the operation of the paste coating device of the repair system for a flat panel display according to the prior art configured as described above are as follows.
[23] First, when the coordinate information on the defect of the flat panel display 4 is confirmed in the previous process, the defect observing apparatus moves to the coordinates to determine the type and size of the defect.
[24] When the defect is judged to be an open defect 6 by the defect observing apparatus and the size of the open defect 6 is detected, the paste applying apparatus pastes the open defect 6 to the open defect 6 using the application needle 2. 8) is applied to correct the defects of the flat panel display 4.
