Mobile electronic device, method for entering screen lock state and recording medium thereof

A method for entering a screen lock state, suitable for a mobile electronic device in an operational state, wherein the mobile electronic device has a touch screen, and the touch screen comprises a status bar display area and an operation area, the method comprising:

• receiving an input signal through the touch screen;
• determining whether a starting point of the input signal is located in the status bar display area;
• obtaining a movement track of the input signal if the starting point is located in the status bar display area;
• calculating a vertical displacement of the input signal when the movement track comprises a specific direction;
• and
• switching the mobile electronic device to the screen lock state when the displacement reaches a predetermined value.

A mobile electronic device, comprising:

• a touch panel, for receiving an input signal, wherein the touch panel comprises a non-display area and a display area;
• an input signal movement detecting module, coupled to the touch panel, for determining whether a starting point of the input signal is located in the non-display area, obtaining a movement track of the input signal if the starting point is located in the non-display area, and calculating a vertical displacement of the input signal when the movement track comprises a specific direction;
• and
• a processor module, coupled to the touch panel and the input signal movement detecting module, for switching the mobile electronic device to a screen lock state when the displacement reaches a predetermined value.
