Abstract
In a sensing method using self-capacitance and mutual-capacitance alternatively to reduce touch noises, a control device configures a first driving and sensing device and a second driving and sensing device to perform an initialization. The control device configures the first and second driving and sensing devices to perform at least one self-capacitance sensing for producing a first possible touch point range during a first work mode. Then, the control device configures the first and second driving and sensing devices to perform at least one mutual-capacitance sensing for producing a second possible touch point range during a second work mode. The control device determines if there is range conjunction between the first and second possible touch point ranges. The control device produces a possible touch point range conjunction and calculates coordinates of touch points based on the possible touch point range conjunction.
