The invention is applicable to the field of electronic equipment, and provides a method for preventing mistakenly touching the edge of a touch control screen. The method comprises the following steps: enabling the edge of the touch control screen to extend outwards to be shaped like a curve surface to be used as the edge of electronic equipment; detecting whether the left edge of the electronic equipment has two or more contact points and the right edge of the electronic equipment has a long contact point or not, so as to judge whether to enter a right hand holding mode or not; if the left edge of the electronic equipment has two or more contact points and the right edge of the electronic equipment has a long contact point, entering the right hand holding mode; detecting whether the pressure of one contact point on the edge of each of the two sides of the electronic equipment is increased or not, so as to judge whether to enter a right hand mistaken-touch prevention mode; if the pressure of one contact point on the edge of each of the two sides of the electronic equipment is increased, starting the right hand mistaken-touch prevention mode, and determining a mistaken touch area as the right edge position of the touch control screen; detecting whether the pressure on the right edge of the electronic equipment is reduced to zero or not, so as to judge whether to terminate the right hand mistaken-touch prevention mode or not; if the pressure on the right edge of the electronic equipment is reduced to zero, terminating the right hand mistaken-touch prevention mode. Through the adoption of the method, when a user operates the touch control screen by one hand, the edge of the touch control screen can be effectively prevented from being touched mistakenly.
