1. Field of the Invention
The present invention is directed to a structure of an enclosure of a portable electronic device, especially a structure of a glass enclosure of a portable electronic device having desired color and pattern decoration as well as durable impact resistance, and a process of preparing the structure of an enclosure.
2. Description of Related Art
Personal portable electronic devices such as mobile-phone, smart phone, tablet-PC, note book-PC, e-book reader had been commonly used now a days. As the market became mature and comparative, design of such device appearance has been diversified and demands to apply various materials such as plastic, metal, wood and glass became overt. Among such materials, there is a demand for glass especially for high grade models because of the superior aesthetic.
Colored glass can be made by adding additives to a glass composition, and it is also possible to make the glass opaque by crystallization of glass by adding proper chemical substances. However it is difficult to make variation of colors with economical ways.
Another issue was durability, especially the application to portable devices, which requires the strength against impact (such as falling down to floor). Chemically toughened glass is usually used for this type of applications. However, compositions of the chemically toughened glass are limited, giving difficulty for obtaining a glass composition that meets other requirement such as appearance.
The present invention gives a glass enclosure article with color and pattern decoration, which has the desired color or texture appearance and also a durable impact resistance. The present invention also provides a process for the preparation of the glass enclosure article with a simple and economical way.
