发明名称 Laser repair structure and method for TFT-LCD
摘要 A laser repair structure and method for TFT panel. A first metal conductor is located in the source-drain layer and having a contact hole to the pixel electrode, and the region of the first metal conductor is within the region of the storage capacitance line. To repair a white defect of a pixel, make extending portions of the first metal conductor to overlap with the gate line of the previous pixel so as to electrically connect them by the laser irradiation. Another choice is setting two second metal conductors located in the gate-electrode layer and partially overlapped with the data line and the first conductor separately, then using laser irradiation to electrically connect one second metal conductor to repair the white defect of a pixel or electrically connect two second metal conductors to repair an open-circuited data line.
