Problems solved by technology

[0014] However, the conventional touch panel manufacturing process using tempered glass substrates with a thickness of 1.8mm or less cut the original glass into individual panes and then required a substrate forming process (transparent electrode layer formation, etc.) on the individual panes, so Process yield is lower than that of the original board

Embodiment Construction

[0033] The preferred embodiments, advantages and features of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] use figure 2 A manufacturing process of a strengthened glass plate using a touch panel with a thickness of 1.8 mm or less according to an embodiment of the present invention will be briefly described. Strengthening treatment (ST200) for multiple original glass sheets. The glass substrate used in the present invention has a thickness of less than 1.8mm, so it is better to apply chemical strengthening method. As explained in the background technology, the chemical strengthening method removes the Na contained in the glass + ions while implanting K + Substance substitution to strengthen glass.

[0035] Thereafter, as a preliminary step before cutting into the size of a cell, chemical etching is performed on the upper and lower surfaces of the original glass along the thickness direction to form the edge o...

Abstract

The present invention relates to a tempered glass sheet for a touch panel, and to a method for manufacturing the tempered glass sheet for a touch panel. The method for manufacturing the tempered glass sheet for a touch panel consisting of tempered glass includes: a first step in which mother glass, including cell glass for a plurality of touch panels, is tempered; a second step in which a process for forming a substrate is performed, which includes forming a transparent electrode by the mother glass unit; and a third step in which, after the substrate-forming process and a half-etching process are completed, the mother glass is cut for the mother glass unit and the cut surface is ground after cutting.

Description

technical field [0001] The present invention relates to a tempered glass plate for a touch panel and a method for manufacturing a tempered glass plate for a touch panel using the same, more specifically, the tempered glass plate for a touch panel of the present invention and the tempered glass for a touch panel using the same The panel manufacturing method chemically etches the edge region of the tempered glass panel for touch panels to form a half-etched state, and then performs a substrate molding process with the original glass plate and cuts it in units of cell glass for use. Background technique [0002] Recently, the advent of touch screen panels (Touch Screen Panel: TSP), which integrates strengthened glass and transparent electrodes, has led to an increasingly competitive structure in the touch screen market. [0003] A touch screen panel (TSP) is a panel that adds a touch function to a flat panel display device such as an electronic manual, a liquid crystal display ...
