Mobile phones formed a huge market of more than 1.2 billion units in 2008, and they are products that can affect touch screens and even many components. The basic function of a mobile phone is a call function, but other functions (email, Web, camera, navigation, etc.) have been added to the mobile phone, and multi-functionality has been gradually developed. On the other hand, digital cameras, portable game consoles, and other dedicated digital machines have also added communication functions, and they have begun to develop in the direction of new services and functions.
Therefore, the boundaries of portable digital devices are becoming blurred. At the same time, many new products targeting this type of product have been launched.
From the point of view of the products derived from mobile phones, the most popular products are smartphones. On the one hand, the standardization of smart phone operating systems such as Windows, Symbian, Mac, and Google can reduce manufacturers' development costs. On the other hand, smart phones have also become a symbol of multifunctional phones. Smart phones can be divided into compact products for PCs represented by Windows phones and multi-functional large-screen products for mobile phones. On the one hand, PC-derived smartphones are centered on commercial use, and their demand is expanding. On the other hand, smartphones derived from multi-functional mobile phones will show an upward trend in the number of integrated touch screens with the improvement of multimedia performance and the standardization of mobile phone operating systems.
With the multifunctionalization of smart phones, various parts are incorporated into the phone.
Therefore, with the development of multi-functionality, the operability has also been reduced, so that more and more consumers are unable to use all its functions fully and flexibly. Application-oriented products that integrate touch screens and small buttons that conform to human operation habits are gradually becoming a key device for improving operability and attracting attention.
Touch screens have been used in mobile phone products for a long time, but most of the integration is to record people with a touch pen. For portable devices including mobile phones, many consumers believe that after integrating a touch screen, in terms of operability, using a touch screen will make people feel that their hands are bound. Also, some people are tired of touching the screen with their hands and smudging the screen. Therefore, touch screens are generally integrated in the Chinese circle with a large number of text strokes and on PDA phones.
In addition to pen input, the Widget function of the smart phone also takes advantage of other features of the touch screen. Widget is a small-capacity client application installed on a mobile phone. It can create application icons for frequently used functions (time, calendar, news, etc.) so that consumers can use custom tools. Most digital devices, including mobile phones, can be connected to the Internet, consumers can freely download application software, and the demand for custom screens is also increasing. The Widget function has a relatively high linkage with the touch screen, which can be said to be different from the touch screen requirements of pen input.
