Abstract
A pixel structure and a method of repairing the same are provided. The pixel structure comprises a first repairing pattern and a second repairing pattern formed together with scan lines and gates. The repairing method includes shorting the repairing patterns (or one of the repairing patterns) from a data line or a pixel electrode in a fusion process using a laser beam to repair the broken signal lines or defective pixels.
Claims19
A pixel structure, comprising:
- a substrate;
- a scan line and a data line, disposed over the substrate;
- a thin film transistor, disposed over the substrate, wherein the thin film transistor comprises a gate, a source and a drain such that the gate is electrically connected to the scan line and the source is electrically connected to the data line;
- a pixel electrode, disposed over the substrate and electrically connected to the drain;
- a contact block, disposed under the pixel electrode and electrically connected to the pixel electrode;
- a first repairing pattern, disposed over the substrate, wherein one end of the first repairing pattern is positioned under the data line while the other end of the first repairing pattern is positioned under the drain;
- a second repairing pattern, disposed over the substrate, wherein one end of the second repairing pattern is positioned under the data line while the other end of the second repairing pattern is positioned under the contact block;
- and
- a dielectric layer, disposed over the substrate covering at least the first repairing pattern and the second repairing pattern.
