In 2008, the mobile phone market reached 1.25 billion units, and it is expected to exceed 1.4 billion units in 2010. With the advent of the iPhone in 2008, the form of touch has also changed, and various mobile phone manufacturers are committed to increasing the integration rate of touch screens. In 2010, mobile phones with integrated touch screens are expected to exceed 200 million. In 2009, the integration rate of mobile phones' touch screens was almost close to 20 percent , and the touch screens used were mainly capacitive touch screens.
Among the touch screen products, in addition to capacitive touch screens, resistive touch screens are also developed. In 2010, the integration rate of touch screens will enter a new year.
Speaking of glass before, the most representative one is the watch cover. In order to realize the thinness and high-end sense of mobile phones, the screen materials of mobile phones are gradually shifting from plastic covers to glass. The use of glass materials in computer monitors and digital cameras has also become a matter of course.
Recently, due to the influence of the iPhone, the surface of the capacitive touch screen is mostly made of glass, and the shape has become more complicated. At the same time, higher requirements have been placed on the strength of the glass. In short, the surface glass is required to have more functions.
Glass processing location distribution: Previously, factories producing glass used in watches were mainly in South China. The main surface glass manufacturers were Fuji Optics, BYD, Vitalink, and Shenzhen lens, but they have recently expanded to East China. With the increase of glass manufacturers, the competition has become increasingly fierce.
The glass materials are mainly Al203 and Si02. The cost of alkaline glass is relatively low, so it is expected that more emphasis will be placed on alkaline glass products. In terms of appearance, because it is integrated on the top, it has strict requirements on appearance specifications such as scratches and foreign matter adhesion. With the improvement of product appearance performance requirements, glass manufacturers are encouraged to improve glass quality management.
In Japan, although the habit of using plastic as a surface is deeply rooted, considering factors such as thinness and high quality, it is better to choose glass, so the use rate of glass is very high. However, there is a risk of breaking when glass is used, so higher requirements are placed on the bonding method and the structure of the anti-scattering film.
