iPhone6 ​​care sapphire shortcomings

With iPhone6 ​​market soon, Apple is also actively seeking innovative technologies to make iPhone6 ​​specifications and features more attractive. Among them, the rumors will replace the sapphire glass Gorilla Glass become iPhone6 ​​protection glass, sapphire material leaving much market attention. As a result, its suppliers GT Advanced's share price over the past year continued to rise, and the related supply chain, even if the use of unsold also followed Apple profitable, attracting many investors attention. 
In fact, before Apple's big move investment sapphire glass, its market under the LED lighting applications and handheld devices are two demands, which have allowed the sapphire substrate manufacturers to actively expand production. Then, Apple will be applied to the rear of the camera lens sapphire protection and fingerprint chip, so the market began to focus on the application of this material. However, the real cause of the market's continuing concern is that Apple will likely generation iPhone on a protective glass, sapphire replacing aluminum silicate glass material, and the size will be 4.7 inches or more. 
One of the most significant sapphire material hardness characteristic is due to its high inherent physical hardness to withstand the daily life of dust, grit and to wear than the glass impact force is more tolerant. However, NPD DisplaySearch noted that the sapphire to become a cell phone screen than with a protective glass or fingerprints on the lens to protect the chip, a higher degree of complexity. In addition to the cost of upgrading beyond reason, not only to consider the protective glass to prevent scratching, optical penetration is also very important factor, because of its impact on the LCD backlight intensity required, thereby affecting the phone's power consumption. 
DisplaySearch said band of light penetrating the material is sapphire most important drawback in the ultraviolet band, although sapphire better penetration than glass, but not as good as in the visible light (390-700nm) Optical transmittance glass, only the former is greater than about 80%, while the latter is greater than 90%. Poor penetration implies backlit LCD panel must be strengthened at the expense of power consumption, which is obviously not desirable smartphone. In addition, the sapphire production is energy-intensive, other refractive index, specific gravity and other factors include higher wisdom will affect the overall size of the phone. Therefore, DisplaySearch believes that the overall smart phone production, the glass is still the more balanced choice. 
Even so, Apple still insist on using sapphire because of patents, technology and supply chain achieved. DisplaySearch said that as long as Apple can be formed through a very special advanced glass processing and downstream manufacturers to protect the supply chain to achieve its patent, then Apple will be able to adopt Hyperion technology that allows sapphire thin protective glass cover on the iPhone as "surface hardness strengthen the function of treatment, "rather than using the entire piece of sapphire material. So, will be able to play hard and wear sapphire advantage, while not overly apparent shortcomings sapphire.
