Abstract: With regard to a learning method for a smartwatch to prevent a metal hand from lightening the screen by unintended touch, a mainboard chip firstly finds and learns points which unintendedly touch the screen. Then, the mainboard chip reserves the time Tm which leads to unintended touch on the screen. The mainboard chip judges the present state: at the reserved time Tm, if the display screen is in an ON state, the display screen will keep the ON state. If the display screen is in an OFF state, the display screen will keep the OFF state.
