[0004] On the other hand, sheet-shaped glass can be produced by the float process (Float Process), or can be produced by methods such as fusion draw process (fusion draw process) and slot draw process (slot draw process). In the case of the melt drawing method or the groove method, there is a disadvantage that the manufacturing cost is expensive

Abstract
A glass article and a method for fabricating the same are provided. The glass article includes a first surface; a second surface opposed to the first surface; a side surface connecting the first surface to the second surface; a first surface compressive region extending from the first surface to a first depth; a second surface compressive region extending from the second surface to a second depth; and a side compressive region extending from the side surface to a third depth, where the first surface and the side surface are non-tin surfaces, the second surface is a tin surface, and a maximum compressive stress of the second surface compressive region is greater than a maximum compressive stress of the first surface compressive region.
Description
technical field [0001] The present invention relates to glass articles and methods of making the same. Background technique [0002] Glass products are widely used in electronic equipment including display devices, building materials, and the like. For example, glass products are suitable for substrates of flat panel display devices such as liquid crystal display (LCD: liquid crystal display), OLED (organic light-emitting diode), and electrophoretic display (EPD; electrophoretic display) or windows for protecting them. [0003] With the increase of portable electronic devices such as smartphones and tablet PCs, glass products suitable for them are also frequently exposed to external shocks. For portability, it is necessary to develop a glass product that is thin and has good strength to withstand external impact. [0004] On the other hand, sheet-shaped glass can be produced by the float process (Float Process), or can be produced by methods such as fusion draw process (fu...
