Methods of fabricating AMLCD tiled displays are disclosed, in which variations in the width and the SIP location of seals are controlled. The seals can be controlled by using either a trench or a dam that guides the flow and/or the position of the sealing epoxy between the upper and lower glass plates. The purpose of the dam or trench is to prevent the flow of epoxy towards the pixels of the display. The article made by the above method is a substantially flat-panel display (FPD) having a mosaic of individual, hermetically-sealed tiles disposed adjacent one another upon the lower plate or substrate. The tiles have visually imperceptible seams between them. The individual tiles have pixels and edges that are sealed in position, relative to the substrate, by means of a sealing material, such as an epoxy. The dams or trenches are disposed along the individual tiles, adjacent the pixels.
