Apple seems to be gearing up to develop a crack resistant and stiffer glass, as seen in the new patent which was published today. The patent states this as “A glass with enhanced stiffness for portable electronic devices like iPhone and iPad.”
The transparent article can form a part of a housing of the portable electronic device and can provide an outer surface for a portion of the housing. The transparent article can be provided over a display of portable electronic device to provide a protective outer cover over the display.
The patent also spoke about the inclusion of sapphire coating to improve strength:
n still another embodiment, a sapphire coating can be deposited on the transparent article to improve it strength. Advantageously, the transparent article is able to be not only thin and lightweight but also provide sufficient stiffness for use as a cover glass.
Apple engineers are constantly exploring newer ways to come up with better glass designs where this patent speaks one of those ideas.
