Method, device and mobile terminal for preventing false-touch on touch screen

A device for preventing a false-touch on a touch screen, comprising:

• an area comparison module configured to compare an area of a touch area corresponding to a touch event with a preset area threshold, when the touch event is detected;
• an area determination module configured to determine whether the touch area corresponding to the touch event overlaps with a touch button area, when the area of the touch area is smaller than the preset area threshold;
• and
• a reporting module configured to mark touch points corresponding to the touch event inside the touch button area as invalid touch points, shield location coordinates of invalid touch points and location coordinates of the touch points inside a preset area, and report location coordinates of remaining touch points, when the touch area corresponding to the touch event partially overlaps with the touch button area;
• and
• report location coordinates corresponding to the touch event, when the touch area corresponding to the touch event does not overlap with the touch button area.

A mobile terminal, comprising a memory, a processor, and a computer program stored in the memory and operable in the processor, wherein the processor implements the following blocks when executing the computer program:

• comparing an area of a touch area corresponding to a touch event with a preset area threshold, when the touch event is detected;
• determining whether the touch area corresponding to the touch event overlaps with a touch button area, when the area of the touch area is smaller than the preset area threshold;
• marking touch points corresponding to the touch event inside the touch button area as invalid touch points, shielding location coordinates of the invalid touch points and location coordinate of the touch points inside a preset area, reporting the location coordinates of remaining touch points, when the touch area corresponding to the touch event partially overlaps with the touch button area;
• and
• reporting location coordinates corresponding to the touch event, when the touch area corresponding to the touch event does not overlap with the touch button area.
