Abstract: An anti-interference driving method of touch panel has steps of providing a touch panel and outputting multiple excitation signal sets to the respective driving lines of the touch panel. The touch panel has multiple driving lines and multiple receiving lines. Each driving line has multiple sub-driving lines. Each excitation signal set has multiple excitation signals sequentially outputted to the corresponding sub-driving lines. The excitation signals outputted to any adjacent two sub-driving lines are reversed in phase and a time gap between the excitation signals with reverse phases is less than a cycle of each excitation signal. Accordingly, two sensing signals having coupled capacitance values of a noise with different signs is obtained by using a receiving line to sense any adjacent two sub-driving lines and can be directly processed to remove the coupled capacitance value of the noise.

Abstract: A multi-functional touchpad remote controller has multiple functional modes to select therefrom and has a touchpad to support touch input. Different patterns may be shown on the touchpad for different functional modes. For the current operation mode, the specific pattern shown on the touchpad allows simple and intuitive to use the multi-functional touchpad remote controller.

Abstract: A method of detecting floating mode of a touch panel has steps of reading a sensing cluster and presetting a detection window; taking each sensing point of the sensing cluster as a center point of the detection window; after determining that the center point has a negative sensing value qualifying to be generated under a floating mode, further determining a count of the sensing points other than the center point having the sensing values generated under a grounding mode and incrementing an accumulative number by one if the count exceeds a first critical value; keeping incrementing the accumulative number until each sensing point in the sensing cluster has been taken as the center point of the detection window for scanning; and determining if the accumulative number exceeds a second critical value, and if positive, further determining that the current sensing cluster is generated under the floating mode.

Abstract: A method for prevention against remiss touch on a touchpad includes dynamically adjusting the scope of an activating area on the touchpad according to a history record of operating the touchpad by the current user, so as to have the protection mechanism against remiss touch automatically adjusted to fit the current user.
