Process and tool for maintaining three-dimensional tolerances for manufacturing tiled AMLCD displays

摘要

There is provided an improved method for laminating the components of a tiled display such as an AMLCD tiled display. In conventional laminating processes, forces are applied to the two parallel glass plates (i.e., the cover and back plates) separated by a liquid adhesive film. The two plates are squeezed together over their entire area forcing liquid laterally out from between the glass plates and tiles until the desired spacing or gap (filled with liquid adhesive) between the cover and back plates and the tiles is obtained. However, this process may require several hours to complete for large panels and, in addition the process is susceptible to trapping air bubbles in the adhesive. Consequently, the traditional process is not well suited for the mass production of large panels. The “pseudo” rolling-like lamination process of the present invention replaces the traditional lamination process and requires significantly less time.
