Flat panel display devices having improved signal line repair capability |
摘要 |
Flat panel display devices having improved signal line repair capability utilize repair lines which have reduced parasitic capacitance with other active signal lines when connected to provide a repair function. This reduced parasitic capacitance is a result of a reduced number of overlaps between active signal lines (or other repair lines) and each repair line performing a repair function. A main repair line is provided on a display substrate to provide a repair function in the event one of the signal lines is defective. If a repair function is needed because a data line is defective (e.g., "opened"), this main repair line is electrically connected to a first end of the defective data line and indirectly electrically connected to a second end of the defective data line. The indirect electrical connection is provided by a sub-repair line, which can be electrically connected (i.e., "shorted") to the main repair line, and a data line extension which is electrically connected to a second end of the defective data line and the sub-repair line. To further reduce parasitic capacitance caused by overlaps between wiring patterns, the main repair line and data line extension are provided at a first wiring level and the data line and sub-repair line are provided at a second wiring level.
