Eagle Touch Technologies Co. Ltd was established in 2007. We started with resistive touch screen production in the beginning and engaged in the Touch Industrial field for more than a decade. With the progress of the touch technology and touch products market expansion, touch screens are used everywhere in our life, public and private spaces like Shopping Malls, Restaurants, Multi-Media, Phones, Computers, Cars, Smart Homes, Hospitals and so on.
Around 10 years ago, the main touch technology was resistive touch Technology and surface acoustic wave touch technology. Then, Infrared touch technology was popular for a while. Nowadays, in today’s market, most consumers are using projected capacitive touch Technology, which features the touch function having advanced from single Touch to real Multi-touch.
Projected Capacitive Technology (PCT) is fast becoming one of the most prevalent touch technologies for an expanding variety of applications ranging from consumer devices to commercial applications in retail, gaming and signage.
Projected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When anger or a conductive stylus approaches an electrode, it disturbs the electromagnetic eld and alters the capacitance. This change in capacitance can be measured by the electronics and then converted into X,Y locations that the system can use to detect touch.
