    • Apparatus, systems and methods for improving strength of a thin glass cover for an electronic device are disclosed. In one embodiment, the glass member can have improved strength by chemical strengthening in a series of stages. The stages can, for example, have a first ion exchange stage where larger ions are exchanged into the glass cover, and a second ion exchange stage where some of the larger ions are exchanged out from the glass cover. Optionally, in one embodiment, the glass cover can improve its strength by forming its edges with a predetermined geometry. Advantageously, the glass cover can be not only thin but also adequately strong to limit susceptibility to damage. In one embodiment, the glass member can pertain to a glass cover for a housing for an electronic device. The glass cover can be provided over or integrated with a display, such as a Liquid Crystal Display (LCD) display.
    • 公开了用于提高电子设备的薄玻璃盖的强度的装置,系统和方法。 在一个实施例中,玻璃构件可以通过一系列阶段中的化学强化具有改善的强度。 这些阶段可以例如具有第一离子交换阶段,其中更大的离子被交换到玻璃盖中,以及第二离子交换阶段,其中一些较大的离子从玻璃盖交换出来。 可选地,在一个实施例中,玻璃盖可以通过以预定的几何形状形成其边缘来提高其强度。 有利地,玻璃盖不仅可以是薄的,而且可以是足够强的,以限制对损坏的敏感性。 在一个实施例中,玻璃构件可以涉及用于电子设备的壳体的玻璃盖。 玻璃盖可以设置在诸如液晶显示器(LCD)显示器之类的显示器上或集成在一起。
