The invention relates to a method for processing a touch screen, in particular to the method for processing the touch screen to be used for reducing product deficiency and improving product productivity to the greatest extent by preventing etching, pattern deficiency and scratch damage caused by foreign matter in the forming process of a capacitance sensing mode. According to the method for manufacturing the touch screen, a conducting layer protective means is used for preventing the foreign matter from flowing into a transparent conducting layer of a touch panel membrane plate and for preventing scratch damage, laser irradiation is conducted on a PET membrane of the touch panel membrane plate to achieve etching processing of the transparent conducting layer. According to the method, the conducting layer protective means is formed on the transparent conducting layer of the touch panel membrane plate, laser irradiation is conducted on the PET membrane of the touch panel membrane plate to achieve the etching processing of the transparent conducting layer, the foreign matter is prevented from flowing into the transparent conducting layer in the laser irradiation etching processing so as to prevent product deficiency caused by etching and scratches, laser irradiation etching is completed on the surface of the conducting layer protective means, and the PET membrane of the touch panel membrane plate can be prevented from being damaged in the laser irradiation etching process.
Description
technical field [0001] The invention relates to a processing method of a touch screen. In more detail, the present invention is on the manufacturing method of touch screen, has the protective means of conductive layer to prevent foreign matter from flowing into the transparent conductive layer of touch panel membrane plate and prevents scratch damage, and then the PET film place of touch panel membrane plate Laser irradiation forms a method of etching a transparent conductive layer. In the process of forming a capacitive sensing pattern, it is a method of processing a touch panel to minimize product defects and improve product productivity by preventing etching defects, pattern defects, and scratch damage caused by foreign substances. Background technique [0002] A general capacitive touch panel is a method of sensing a position based on a change in capacitance that occurs when touched. The above capacitive touch screen is composed of a transparent conductive layer formed...
