    摘要: A capacitive touch device includes a capacitive touch panel, a driving control unit, k ADCs, a multiplex network and a processing unit. The capacitive touch panel has an m×n sensing point matrix formed by m driving line and n sensing lines. The driving control unit is coupled to the m driving lines. The multiplex network connects the n sensing lines and the k ADCs by time-domain multiplexing. The processing unit is coupled to the k ADCs. At least a part of the driving lines and at least a part of the sensing lines are assigned to be electrically connected. The processing unit senses according to multiple frequencies to obtain multiple signal strength values, and selects the frequency corresponding to a smallest signal value to be a sensing frequency of the capacitive touch device.

    摘要: A gesture detecting method capable of filtering a panel mistouch includes following steps is provided. First, an area of a touch region for a touch event on a touch panel is detected. Next, it is determined whether the area of the touch region is greater than a minimum predetermined area value and smaller than a maximum predetermined area value. When a result of the above determination is affirmative, whether a shape of the touch area is a mistouch shape is determined. Finally, when the shape of the touch region is the mistouch shape, a set of touch coordinates is not reported.
