Abstract:
1. A method for sampling coordinates of a touched point on a touch panel, comprising: (a1) detecting a touched point on a touch panel at a low detection frequency to obtain two touch coordinates sequentially in time series; (a2) calculating a distance between the two touch coordinates at the low detection frequency; (a3) determining whether the distance between the two touch coordinates at the low detection frequency is greater than a first threshold distance; (a4) detecting a touched point on the touch panel at a high detection frequency to obtain a subsequent touch coordinate in time series when the distance is greater than the first threshold distance in the step (a3); (a5) calculating a distance between two touch coordinates sequentially in time series at the high detection frequency; (a6) determining whether the distance obtained in the step (a5) is less than a second threshold distance, wherein the second threshold distance is less than the first threshold distance; and (a7) detecting a touched point on the touch panel at the low detection frequency when the distance is less than the second threshold distance in the step (a6).
