Abstract: A sense signal is continuously received from a capacitive touch-sensing panel. A reference signal is set or adjusted to have a level of the sense signal be in a first relation to that of the reference signal in an initial state, and the sense signal is compared with the reference signal to generate a comparison signal in a sensing state. The comparison signal is outputted with a first logic level when a level of the sense signal is in the first relation to a level of the reference signal, and outputted with a second logic level when a level of the sense signal is in a second relation to a level of the reference signal. Whether a touch action is conducted is determined according to a compared result of occurrences of the first and second logic levels of the comparison signal generated within a preset time period.

Abstract: A floating touch method and a touch device are provided. The touch device includes a capacitive touch panel and a sensor circuit. The capacitive touch panel includes separate electrode units and connecting traces corresponding to the separate electrode units one-on-one. At first, the sensor circuit controls the capacitive touch panel to sense a control object within different sensing ranges at different time points to determine a distance-related value between the control object and the capacitive touch panel. Then, the sensor circuit controls the capacitive touch panel to detect a floating touch action of the control object based on the distance-related value. Subsequently, the sensor circuit issues a control signal corresponding to the floating touch action to enable the touch device or the capacitive touch panel to perform a specific function.

Abstract: For sensing a control point on a capacitive-type panel, first and second voltage signals are respectively received through two sets of receiving lines selected from N receiving lines in response to first and second charge/discharge signals transmitted through two sets of transmitting lines selected from M transmitting lines, respectively, during a specified time period. A characteristic value is generated by operating the first and second voltage signals. Repeat the steps to generate characteristic values for neighboring regions defined by different combinations of transmitting lines and receiving lines. Position information of control point(s) on the capacitive-type panel is estimated accordingly.
