Patent ID: 7964820

Claim:
A method for accurately laser scribing lines in thin coatings on a panel, utilizing a laser beam scanner unit including an optical system and a scanner lens, the method comprising the steps of: a) using the scanner unit to move a laser beam in a first direction (X) to scribe sections of lines on the panel that are running parallel to the first direction (X) and that are a fraction of a total line length required; b) moving the scanner unit continuously with respect to the panel in a second direction (Y), perpendicular to the first direction (X), to form a band of scribe lines, the band having a width in the first direction (X); and c) repeating the using and the moving steps to form a plurality of parallel bands of scribe lines to cover the full area of the panel with continuous scribe lines in that the scanner unit is positioned so that the starting position of scribe lines in each band next to be processed overlap exactly finishing position ends of scribe lines in a last band that has been processed so that all scribe lines interconnect to rows of scribe lines which run parallel to the first direction (X), the rows forming the continuous scribe lines.
