For example, the weight value of the writing circle may be determined by the radius of the writing circle and the distance between the center of the writing circle and the corresponding test point. For another example, the farther the distance between the center of the written circle and the test point, the smaller the weight value of the written circle, the larger the radius of the written circle, and the smaller the weight value of the written circle.

Or determining the coefficient of the standard deviation corresponding to the writing circle by utilizing the radius of the writing circle and the distance between the center of the writing circle and the corresponding test point. For example, the farther the distance between the center of the written circle and the test point, the larger the coefficient of the standard deviation corresponding to the written circle, the larger the radius of the written circle, and the larger the coefficient of the standard deviation corresponding to the written circle. The coefficient of the standard deviation may be a positive integer.

S all ＝S D +3*S σ
wherein S is all Representing touch accuracy of a touch screen, S D Mean value of accuracy of touch points on touch screen is represented, S σ And representing the standard deviation of the precision of the touch point on the touch screen.
According to the embodiment, the product of the standard deviation of the precision of all the touch points on the touch screen and the second coefficient is summed with the average value of the precision of all the touch points on the touch screen, so that the touch precision of the touch screen is accurately obtained.

Or, when the total number of the test points with the precision smaller than the second precision is larger than the set quantity threshold value, adjusting the touch detection application program of the touch screen. Wherein the first precision may be less than or equal to the second precision.
