摘要： An electronic device control method applied to an electronic device can operate in a display mode and a touch sensing mode. The method comprises: (a) controlling the electronic device to have a first mode switch frequency; and (b) controlling the electronic device to have a second mode switch frequency different from the first mode switch frequency. The first mode switch frequency and the second mode switch frequency are frequencies for switching between the display mode and the touch sensing mode.

摘要： A touch panel includes a cover lens located at top of the touch panel, plural touch sensor units, and plural sensing channels. The touch sensor units are disposed below the cover lens and arranged in rows and columns. The touch sensor units are disposed on the sensing channels. Each of touch sensor units acquires a sensing magnitude for identifying a position of the cover lens that touched by the stylus according to signals outputted by the sensing channels. The sensing magnitude of one of the touch sensor units is composed of the signals of the adjacent sensing channels located within a vertical projection of the one of the touch sensor units.
