Apple was 3 copies of sapphire related patents: production screen, light-emitting button?

Many sources pointed out that Apple will be released this fall with sapphire glass screen iPhone. Today, the United States Patent and Trademark Office (USPTO) released three copies of Apple patents, these patents are associated with sapphire glass technology, patent refers to the use of sapphire glass production equipment and technology of light emitting screen iOS button. The first patent was called the "sapphire glass components" residual pressure, this patent describes a method on alumina ceramic (sapphire) material shaping and selective generation of residual pressure, this method can make the sapphire glass on the fragile areas of stronger.

Earlier this month, a meaning iPhone 6 sapphire glass display video, although the video iPhone 6 screen material is not confirmed, but tests show that can deal with all kinds of materials to withstand extreme scratching and bending, these attributes are not the Corelle gorilla glass. Patents mentioned in this enhanced sapphire glass technology suitable for use in the front panel or the back of the shell. In order to improve the shock and impact, the residual compressive stress can be applied to the outer layer of sapphire glass.

Any suitable technique can be used to create residual compressive stresses, such as heat treatment, tempering, quenching or other such techniques. Laser heating or strengthening can also be used for more precise control. Depending on the installation of sapphire glass equipment, resistance to residual compressive stresses can be implemented at the edge or center.

Apple's second patents related to sapphire is known as the ceramic insert control mechanism, the patent describes the use of sapphire material for physical control, such as the Home button, volume keys, etc.. The patent describes the operation of the sapphire parts by pressing, sliding and manually switching components. These controls can be installed on the shell of the device, or insert a sapphire glass screen, such as the iPhone Home key.

In order to prevent damage, bearings, insulators or gaskets can be installed around the sapphire parts. These parts can be opaque or identical to the refractive index of sapphire. Currently, the use of Touch ID sapphire glass material, this material can protect the internal sensitive circuit. Apple referred to the use of LED lights in the patent for the sapphire component.

The third patent is known as an "ion - implanted label for a screen - protected glass or display module, which creates a mark at the bottom of the sapphire glass screen, such as a serial number or a trademark.". Through the use of ion implantation technology, the change of the sapphire material of the light or color in the subsurface layer, can leave a mark, it is easy to read, but also. The possible ions used in the process include chromium, titanium, or iron, which are then accelerated in the electric field and injected into the sapphire element. Different ions can be used to create different color markings, while some methods may only slightly change the perception of the optical quality of the glass.
