Abstract
A touch compensation method includes: for at least one line, estimating coordinates of a point to be compensated at a current moment according to coordinates of n touch recognition points at n previous moments, and n being an integer greater than or equal to 2; calculating compensation data of a touch model corresponding to the point to be compensated according to first touch data of a touch model corresponding to a touch recognition point of a previous 1st moment T1; obtaining all touch data of a touch screen at the current moment, and obtaining second touch data at the current moment at a place where the touch model corresponding to the point to be compensated is located from the all touch data according to the coordinates of the point to be compensated; and compensating the second touch data according to the compensation data.
