Capacitive touch technology and pressure sensing technology have been promoted for many years. Although capacitive touch technology has become the standard equipment of smart phones many years ago, the development of pressure sensing technology in smart phones has been tepid. Even since the beginning of 2018, it has been reported that some new generation iPhone models will cancel the use of this technology, which has a great impact on the supply chain.
In smart phone applications, capacitive touch technology is becoming more and more important. In addition to spanning the display field and biometrics, various functions realized through capacitive touch chip algorithms also affect people’s use habits. For example, pressure sensing technology can enable users to operate various functions of smart phones more finely. After Apple introduced the pressure sensing technology into the iPhone in 2015, the relevant supply chain had expected this technology to flourish. However, not only has the Android camp not adopted it on a large scale, but there are even rumors that some iPhone models may abandon this technology, and the subsequent development deserves close attention.
Since the introduction of capacitive touch screen into iPhone, whether it has finger touch interface technology has become an indicator for consumers to distinguish between smart phones and functional phones. It also brings relevant manufacturers of capacitive touch technology across Asia, and capacitive touch chip is the key role to promote this trend. With the annual decline in the price of mobile phone capacitive touch chips and the transfer of capacitive touch chips, the output value of global smart phone capacitive touch chips has remained at about US $1.4 billion in the past few years.
According to the latest research of Tuo long, the output value of capacitive touch chip of smart phone will be sharply reduced to US $1.1 billion in 2018, mainly because most new mobile phone cases have long replaced single touch technology with multi touch technology, the growth space of product unit price is limited, and the large number of cases of introducing display touch integration chip scheme in 2018, As a result, the output value of smart phone capacitive touch chip was negative 8% from 2015 to 2018.
