Projection type capacitive touch IC trend continued good

Beijing time on July 10, news, China touch screen network, market research firm IHS pointed out that benefit from smart phones and tablet device market demand continued to be strong, and notebook computer uses the proportion rising, global projected capacitive touch IC market value, from $19 billion in 2013, $2.3 billion in 2014 increased to,, the annual growth rate of 21%; prediction in 2015, will continue to maintain double-digit growth, the scale of production is expected to reach $26 billion.

The current global touch screen market has been half the use of capacitive touch (surface capacitance or projected capacitive sensing mechanism), and widely used in many mobile consumer products, such as smart phones and tablet PCs; in addition, capacitive touch also began to be applied in its field, including home appliances, industrial control equipment and smart home.

Although the low cost of the resistive touch screen is also applicable to many other products, but with capacitive touch screen based human machine interface (HMI) can also enhance the brightness of the display and response time, which makes more and more engineers in droves, based on capacitive touch sense of measuring technology of multi touch features, in the next few years also is expected to become the mainstream of HMI.

Multi touch operation can detect many complex actions, and provide users with more intuitive, simple operation. In addition, multi touch allows more people to use the same man-machine interface, to create a multi user experience sharing. If capacitive touch can be realized as the above functions, it is clear that the engineering team will generally use the traditional human machine interface design architecture, to ensure that they can achieve this technology in the most effective way.
