The touch screen market will have higher growth

Apart from the mobile phone and personal entertainment market, the application of touch screen is also increasing in the car multimedia, laptop and e-book industries. The resistance type touch screen has been used for many years, but the capacitive type will be the trend of future development, because its operation is more humane. The iPhone cell phone and iPad laptop use the capacitive type, and its application is more and more wide.

The resistance type touch screen technology is cheap and mature, which is more used in the small size cell phone. The growth rate of cell phone touch panel will be thirty-three percent from 2009 to 1013. The demand for touch panel is three hundred million, the demand for resistance type and capacitive type is 198 million and 96 million respectively in the year. of 2010. Thus, it can be seen that the capacitive type is going to replace the resistance type. With the cost reduction of the capacitive type and its application in smartphones, the market share of the resistance type will shrink rapidly.

From the point of view of the laptop, the permeability of the touch screen of the capacity type in the laptop and netbook is 3.7% and 25%, respectively. With the emergence of Windows 7 and iPad, the application of the capacitive type will be more and more on the laptop.

There are two main development directions of touch screen technology; one is the multi-point touch which is close to induction technology. Multi-point touch allows many people to work on the same screen, such as playing games, drawing, engineering design, and image processing. The other trend is to integrate the touch screen with the LCD screen. Currently, many manufacturers have started the development of embedded products to reduce the cost and thickness. The related integrated circuit is K102P.
