Abstract

The invention provides a method of repairing the defects in an electrode pattern, containing: executing a detecting program to detect if the electrode pattern on the plasma display has defects, executing a first repairing program to fill the sunk parts and executing a second program to eliminate the raised parts. In the first repairing program, it uses conductive plasma to fill the sunk parts and in the second one, uses a laser beam to eliminate the raised parts, so as to give full play to stable discharge of the electrode.

Description

Technical field

[0001] The present invention provides a method for repairing defects, especially a method for repairing electrode pattern defects by using conductive materials and laser beams. Background technique

[0002] With the development of the electronic information industry, the application and demand for flat panel displays (FPD) continue to expand. Among them, plasma display panes (PDP) have been developed due to their small size, large size, and wide viewing angle. It has become a product with great development potential in flat panel displays.

[0003] The plasma display mainly includes a front substrate, a back substrate, an ionized gas (not shown) filled between the front substrate and the back substrate to generate ultraviolet rays, and a plurality of pairs of sustain electrodes parallel to each other ( The sustain electrode) is set on the surface of the front substrate for discharge. The front substrate further includes a plurality of auxiliary electrodes (bus ele...
