MANUFACTURING PROCESS AND STRUCTURE OF EDGE-CHAMFERED ONE-GLASS-SOLUTION TOUCH PANEL

摘要

A method for manufacturing an edge-chamfered OGS touch panel is disclosed. Before a pre-prepared glass substrate is subjected to etching, an upper lamination film and a lower lamination film are respectively laminated on upper and lower surfaces of the glass substrate. The upper lamination film is smaller than the lower lamination film so that when the upper lamination film is laminated on the surface of the glass substrate, an edge exposure zone is preserved on the glass substrate at a location adjacent to a substrate edge. When the substrate edge of the glass substrate is subjected to etching, a chamfered edge is formed on the touch operation surface of the glass substrate that is adjacent to the substrate edge.

1. A method for manufacturing an edge-chamfered one-glass-solution touch panel, comprising the following steps:
(a) providing a large-sized glass panel, which has a first surface and a second surface; (b) forming a plurality of touch units on the second surface of the large-sized glass panel and defining a cutting line between adjacent ones of the touch units, wherein each of the touch units comprises a touch circuit and an edge frame corresponding to the touch circuit; (c) cutting the large-sized glass panel along the cutting lines to form a plurality of glass substrates, wherein the first surface of each of the glass substrates serves as a touch operation surface and the second surface thereof serves as a circuit formation surface and the glass substrate has two opposite substrate edges; (d) laminating an upper lamination film and a lower lamination film respectively on the touch operation surface and the circuit formation surface of each of the glass substrates, wherein the upper lamination film has a first width and the lower lamination film has a second width and the first width of the upper lamination film is smaller than the second width of the lower lamination film so that the upper lamination film is laminated on the touch operation surface of the touch unit to form an edge exposure zone on the touch operation surface of the glass substrate at a location adjacent to each of the edges; (e) subjecting the edges of each of the glass substrates to etching with an etchant agent so that the substrate edges of the glass substrate are etched off and the touch operation surface of the glass substrate is formed with a chamfered edge at a location adjacent to each of the substrate edges; and (f) peeling the upper lamination film and the lower lamination film from the touch operation surface and the circuit formation surface of each of the glass substrates.
