DEVICE AND METHOD FOR MANUFACTURING PET FILM FOR TOUCH PANEL USING LASER ETCHING METHOD

摘要

The present invention relates to a device for manufacturing a PET film for a touch panel using a laser etching method. The present invention provides the device for manufacturing a PET film which comprises: a PET film supply unit supplying a PET film coated with a transparent conductive matter and wound around on a first roller, by unwinding the PET film; a laser etching unit forming a signal pattern by etching the PET film coated with the transparent conductive matter supplied from the PET film supply unit with a laser; and a PET film accommodation unit rewinding the PET film on which the signal pattern is formed by the laser etching unit with a second roller. According to the present invention, the device can form a signal pattern in one etching operation by forming an X axis and a Y axis on a transparent conductive matter layer of the PET film using the laser etching method. The device also can perform an automatic etching operation by supplying the PET film in a roll-to-roll method and accommodating the PET film which is laser etched.;COPYRIGHT KIPO 2014
