Abstract

A rigid substrate, a touch panel including the rigid substrate, and a processing method of the rigid substrate are provided. The rigid substrate includes an ion strengthened surface layer completely covering the entire outer surface thereof. The rigid substrate has an etched wall, wherein an average depth of the ion strengthened surface layer on the etched wall is substantially equivalent to an average depth of the ion strengthened surface layer outside of the etched wall.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority benefit of Taiwan application serial no. 101119366, filed on May 30, 2012. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND

[0002] 1. Field of the Invention

[0003] The invention relates to a substrate, a touch panel, and a processing method of the substrate. More particularly, the invention relates to a rigid substrate, a touch panel including the rigid substrate, and a processing method of the rigid substrate.

[0004] 2. Description of Related Art

[0005] As probabilities for users to be in direct contact with panel devices significantly increase, possibilities of damaging the panel devices due to lack of mechanical strength may also increase. Therefore, the mechanical strength of the panel devices has become an important factor in indicating a durability of electronic products. Currently, a strengthened substrate (...

Embodiment Construction

[0033]It is noted that a depth of an ion strengthened surface layer of a glass in embodiment of the invention is referring to an average depth of potassium ions diffusing from the outer surface into the interior of the glass, and a better definition is referring to an average value of maximum diffusion depths of the potassium ion when a plurality of areas are divided out on the entire outer surface of the glass. The depth of the ion strengthened surface layer generally may be obtained by utilizing an instrument to detect whether the potassium ions are present. Since even under a same manufacturing process the diffusion depths of the ions would still vary, the invention adopts the average value of the diffusion depths as a standard for determining the depth of the ion strengthened surface layer.

[0034]Namely, in an embodiment, the depth of the ion strengthened surface layer may be defined as a value obtained from averaging the corresponding measured depths of a plurality of measuring ...
