Abstract:
1. A method of fabricating a display comprising: stacking a layer of display media and at least two layers of thermoplastic polymer, said display layer being disposed between said polymer layers; and simultaneously cutting and welding said polymer layers in a presence of said display media as a contaminant to a bond between said polymer layers using a laser beam by continuously moving said laser beam in a first direction within a plane of said layers and in a second direction transverse to said first direction within said plane, thereby forming a cut pattern, wherein said cut pattern has an amplitude in said second direction that ranges from 20 to 500 micrometers and a period in said first direction that ranges from 50 to 1000 micrometers, wherein said cut and welded polymer layers formed in said cut pattern enable said display to avoid delamination when subjected to forces propagated in various directions.
