Abstract
Electronic flat panel displays (FPDs) including liquid crystal displays (LCDs) may be resized to meet custom size requirements for applications in aerospace and elsewhere. During the resizing process, pixel line defects may occur in the image due to electrical short circuits at the resized cut edge. Methods for repairing such short circuits are described, including use of mechanical, electrical, chemical, thermal, and/or other methods, and any combination thereof, to open the short circuits. The methods may be applied to the sealed cut edge to ruggedize the seal, even if image defects are not exhibited initially. The repaired short circuits may be stress tested to ensure the defects will not recur during the life of the display, and the repaired areas may be resealed.
