Method for manufacturing a pad for a touch panel, and pad for a touch panel manufactured by same

Abstract

The present invention relates to a method for manufacturing a pad for a touch panel and to a pad for a touch panel manufactured by same, wherein the method comprises the steps of: preparing a pad, which includes a light-transmitting insulator layer made of an organic insulator or an inorganic insulator, a light-transmitting conductor coating layer formed at a top of the light-transmitting insulator layer, and a metal coating layer formed at a top of the light-transmitting conductor coating layer, for manufacturing a touch panel; etching, from the metal coating layer of the pad for manufacturing the touch panel, at least a portion of the metal coating layer corresponding to a window, while leaving a portion of the metal coating layer corresponding to a lead line unetched; and etching the etched pad for manufacturing the touch panel to form the lead line and a touch pattern.; Through such operations, residual defects, consisting of metal dots left due to defective etching of the metal coating layer, are removed from a window portion, which is required to be transparent without blemishes when the pad is coupled to a display device such as an LCD, and thus the manufacturing yield of the pad for a touch panel can be improved.

Description

technical field [0001] The present invention relates to a method for manufacturing a sheet for a touch panel and a sheet for a touch panel manufactured according to the same, and particularly relates to a window part capable of being cleanly and transparently displayed without stains or the like when it is required to be combined with a display device such as an LCD at a later stage. A method of producing a touch panel sheet that improves the productivity of a touch panel sheet due to a residue defect in which metal remains in dots due to poor etching of a metal coating layer, and a touch panel sheet produced therefrom. Background technique [0002] As a raw material sheet before processing for making a conventional touch panel, a laminated sheet coated with ITO on an insulating layer such as glass or insulating resin is used. In order to realize the ITO (Indium Tin Oxide, Indium Tin oxide) pattern layer is electrically connected to the outside, generally using silver paste....

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above problems, the object of the present invention is to provide a method of manufacturing a sheet for a touch panel and a touch panel manufactured according to the same, so that when a display device such as an LCD is combined with the lower part of the touch panel, there is no stain when required. In the window part that is displayed cleanly and transparently, it eliminates the residue defect that the metal remains in the form of dots caused by the poor etching of the metal coating, and improves the productivity of the touch panel sheet
