摘要： A controller for position detection is disclosed. At least one first 1-D position corresponding to at least one external object is determined based on signals of a plurality of first sensors by self-capacitance detection. Each first 1-D position is determined based on a differential sensing information whose each value is based on signals of two first sensors by self-capacitance detection. Then, at least one second 1-D position corresponding to the at least one first 1-D position is determined based on signals of a plurality of second sensors by mutual-capacitance detection.

摘要： A method and device for dual-differential sensing is disclosed. The sensing information can be generated from signals provided by a sensing device with a plurality of sensors. Each value of the sensing information corresponds to signals of three sensors, respectively. The sensing device is flexible and configured on a display. The noise effect of the display on the signal of each sensor corresponds to the distance between the display and the sensor. Besides, the noise effect of the display on each value of the sensing information corresponds to the distances between the display and the three sensors, respectively.
