Processing a Plate-Like Workpiece having a Transparent, Glass, Glass-Like, Ceramic and/or Crystalline Layer

摘要

A plate-like workpiece having a transparent, glass, glass-like, ceramic and/or crystalline layer, such as for use in an electronic display screen, is processed into separate segments by first incompletely severing the workpiece along outer contours of bounded segments, by forming holes through the layer with a laser beam, leaving the segments interconnected at narrow connections, and then separating the segments by severing the web-like connections.

主权项

1. A method for processing a plate-like workpiece having a layer of a transparent, glass, glass-like, ceramic and/or crystalline material to form a plurality of partial segments of the plate-like workpiece, the method comprising:
incompletely severing the partial segments from the rest of the workpiece by forming holes along an outer contour of each partial segment, the formed holes each extending completely through a thickness of said layer, leaving each partial segment connected to other portions of the workpiece by at least one web-like connection; and then separating the partial segments by severing the web-like connections.
