Projected Capacitive Touch Technology
With the recent explosion in popularity of the smart phones, projected capacitive touch has grown extremely rapidly from obscurity to the top-notch touch technology.
Projected capacitive, the touch technology used in the iPhone touch screen, has become the first choice for many small-to-medium, generally smaller than 10 inches, touch-equipped products now in development.Projected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When a finger or a conductive stylus is near the electrode, it disturbs the electromagnetic field and changes the capacitance of the electrode. 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. There are two main types of sensing methods, self-capacitance and mutual capacitance.
P-Cap touch screen includes features such as 10ms response time, no touch pressure required, making touch response accurate, fast and sensitive.
Compared to traditional surface capacitive touch screen, P-Cap touch screen is completely flat, offering sleek, refined appearance. That can prevent dust gathering effectively and make cleaning easier.
Whether in consumer electronics application or commercial application, P-Cap touch screen with multi-touch capability can bring better interactive experience to users.
After years of development, P-Cap technology widely used in portable mobile devices such as mobile phones, tablets and so forth has been very mature and recognized by the consumer electronics market. Meanwhile, P-Cap technology has also been applied in commercial field.
