    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: 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 first time period. Third and fourth voltage signals are received through two sets of receiving lines selected from the N receiving lines in response to third and fourth charge/discharge signals respectively transmitted through the two sets of transmitting lines, respectively, during a second time period. A characteristic value is generated according to the first, second, third and fourth 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.

    Abstract: A touch-sensing electronic device with a press-sensing function includes a cover lens formed with a shielding structure at a first side thereof; a display formed with a first group of sensing electrodes and a second group of sensing electrodes at a second side thereof, wherein the second group of sensing electrodes are spaced from and electrically shielded with the shielding structure while the first group of sensing electrodes are unshielded from the shielding structure; and a control chip electrically connected to both the first group of sensing electrodes and the second group. The control chip senses a first capacitance change occurring in response to a touch-sensing operation at a third side of the cover lens, which is opposite to the second side and senses a second capacitance change occurring in response to a press-sensing operation at the third side of the cover lens.

The biological feature-sensing device includes a capacitive touch panel and a control circuit. The capacitive touch panel includes signal transmitting lines and signal receiving lines. A first pitch of the signal transmitting lines or a second pitch of the signal receiving lines is greater than or equal to a minimum on-center spacing of the biological feature. The control circuit receives first and second voltage signals through two sets of signal receiving lines in response to first and second charge/discharge signals transmitted through two sets of signal transmitting lines, and generates a characteristic value according to the first and second voltage signals. Many characteristic values corresponding to different combinations of the signal transmitting lines and signal receiving lines are generated accordingly to form a characteristic value matrix representing the biological feature information.

    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.
