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.
