  • Patent number: 9632336
    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.

  • Publication number: 20130115845
    Abstract: Pre-manufactured electronic displays and, in particular, liquid crystal flat-panel displays, may be cut to a new size and resealed while preserving their originally-manufactured properties. A display may be cut, and the exposed edge of a target portion may be sealed, e.g., to preserve the integrity of the target portion of the display. It may be desirable to cause a sealant to go in between the plates of the panel, e.g., to achieve improved yield, chemical isolation, dimensional integrity, and/or strength of the seal. Apparatus and methods are disclosed where the sealant is injected or otherwise forced into the region between the plates adjacent the exposed edge. This sealing process may achieve more sealant surface contact area inside the panel in between the plates, e.g., to achieve better bonding strength, chemical isolation, and/or improved yield.
