Capacitive touch screen technical specifications

Capacitive touch technology is the use of fingers close to the capacitive touch panel when the capacitance change of touch technology. Capacitive touch has two important capacitance parameters, one is the inductive capacitance between the finger and the upper sensing material (such as ITO), and the other is the parasitic capacitance between the sensing material (such as the upper and lower layers of ITO) or between the sensing material and the optical panel (such as ITO and LCD). Parasitic capacitance is generated between conductors and conductors, and induced capacitance changes when a finger conductor approaches a sensing conductor of different voltages. The capacitive sensing effect is how the larger parasitic capacitance value (30 pico Farad; pF), the detection of 0. 1 to 2 pF units of the small inductive capacitance change. Capacitive touch technology is more stable and reliable, by the human body is an Atmel marketing director Christopher Ard pointed out that the sensor design can be a single-sided ITO graphics for the minimum functional interface, such as a single touchpoint for large virtual buttons, sliders, and other applications, but the more common implementation is a two-layer design (separate X and Y layer), which requires a higher degree of complexity. This then requires a higher level of complexity for performance and accuracy.
