Abstract

The embodiment of the disclosure discloses a method and a device for preventing a false-touch on a touch screen, a mobile terminal and a storage medium. The method may include comparing an area of a touch area corresponding to the touch event with a preset area threshold, when the touch event in response to receiving a touch input 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 a preset area threshold, and reporting or shielding location coordinates corresponding to the touch event, according to the determination result. The embodiment of the disclosure solves the problem that the touch input in the touch button area of the touch screen cannot be accurately detected thereby the anti-missing function is invalided. Improving the accuracy of the contact reporting in the multi-touch input and implement the effect of improving the processing accuracy of the screen touch event of the mobile terminal are achieved.

Claims

21. A method for preventing a false-touch on a touch screen, comprising:

comparing an area of a touch area corresponding to a touch event with a preset area threshold, when the touch event in response to receiving a touch input is detected, the touch input comprising at least one touch point;

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; and

reporting or shielding location coordinates corresponding to the touch event, according to the determination result.

22. The method as claimed in claim 21, wherein the step of comparing an area of a touch area corresponding to a touch event with a preset area threshold comprises:

determining whether the touch input is outside a preset area, according to the location coordinates corresponding to the touch event; and

if the touch input is inside the preset area, comparing the area of the touch area with the preset area threshold.

23. The method as claimed in claim 22, wherein the step of comparing an area of a touch area corresponding to a touch event with a preset area threshold, further comprises:

if the touch input is outside the preset area, reporting the location coordinates corresponding to the touch event.

24. The method as claimed in claim 22, wherein before the step of determining whether the touch input is outside an preset area, according to the location coordinates corresponding to the touch event, the method further comprises:

setting the preset area according to a holding manner and a posture of the touch screen.

25. The method as claimed in claim 22, wherein the step of comparing an area of a touch area corresponding to a touch event with a preset area threshold comprises:

calculating a sum of areas of touch points of the touch input corresponding to the touch event; and

comparing the sum with the preset area threshold.

26. The method as claimed in claim 22, wherein the preset area is located on a left side or a right side of the touch screen, or located on a bottom left corner or a bottom right corner of the touch screen.

27. The method as claimed in claim 21, wherein the step of determining whether a touch area corresponding to the touch event overlaps with a touch button area comprises:

determining the touch area according to the touch input corresponding to the touch event;

comparing the touch area with the touch button area; and

if at least one of the touch points is inside the touch button area, determining that the touch area corresponding to the touch event overlaps with the touch button area.

28. The method as claimed in claim 21, wherein the step of reporting or shielding location coordinates corresponding to the touch event, according to the determination result comprises:

marking the touch point inside the touch button area as an invalid touch point, when the touch area partially overlaps with the touch button area;

shielding the location coordinates of the invalid touch point and the location coordinates of the touch point inside the preset area; and

reporting the location coordinates of the remaining touch points of the touch input.

29. The method as claimed in claim 21, wherein the step of reporting or shielding location coordinates corresponding to the touch event, according to the determination result comprises:

shielding the location coordinates of the touch input when the touch area completely inside or overlaps with the touch button area.

30. The method as claimed in claim 21, wherein the step of reporting or shielding location coordinates corresponding to the touch event, according to the determination result comprises:

reporting the location coordinates of the touch input when the touch area does not overlap with the touch button area.

31. The method as claimed in claim 21, wherein the touch button area comprises a touch button, a blank portion between the touch button and a frame of the touch screen.

32. 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 report or shield touch coordinates corresponding to the touch event according to the determination result.

33. A mobile terminal, comprising a memory, a processor, and a computer program stored on the memory and operable on 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 in response to receiving a touch input is detected, the touch input comprising at least one touch point;

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; and

reporting or shielding location coordinates corresponding to the touch event, according to the determination result.

34. The mobile terminal as claimed in claim 33, wherein the step of comparing an area of a touch area corresponding to a touch event with a preset area threshold, comprises:

determining whether the touch input is outside a preset area, according to the location coordinates corresponding to the touch event; and

if the touch input is inside the preset area, comparing the area of the touch area with the preset area threshold

35. A non-transitory computer readable storage medium, storing a program comprising instructions executable by a processor to cause the processor to perform operations including:

comparing an area of a touch area corresponding to a touch event with a preset area threshold, when the touch event in response to receiving a touch input is detected, the touch input comprising at least one touch point;

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; and

reporting or shielding location coordinates corresponding to the touch event, according to the determination result.
