摘要： The present disclosure provides a laser etching system for electrode layer patterning, which can perform electrode layer patterning on the conductive layer of a first surface of the substrate of a double-sided structure touch panel by means of employing a laser beam without damaging the conductive layer on the second surface of the substrate. The system comprises a laser emitter for generating and emitting laser beams, and a laser etching platform for supporting and fixing the touch panel substrate, with the first surface facing the laser beam and the second surface adhering to the laser etching platform. The laser etching system further comprises optical elements, which ensure that the ratio of the spot size of the laser beam irradiated on the second surface to that irradiated on the first surface is not less than 1.2.
